Background Despite international guideline recommendations, low back pain (LBP) imaging rates have been increasing over the last 20 years. Previous systematic reviews report limited effectiveness of implementation interventions aimed at reducing unnecessary LBP imaging. No previous reviews have analysed these implementation interventions to ascertain what behaviour change techniques (BCTs) have been used in this field. Understanding what techniques have been implemented in this field is an essential first step before exploring intervention effectiveness. Methods We searched EMBASE, Ovid (Medline), CINAHL and Cochrane CENTRAL from inception to February 1, 2021, as well as and hand-searched 6 relevant systematic reviews and conducted citation tracking of included studies. Two authors independently screened titles, abstracts, and full texts for eligibility and extracted data on study and intervention characteristics. Study interventions were qualitatively analysed by three coders to identify BCTs, which were mapped to mechanisms of action from the theoretical domains framework (TDF) using the Theory and Techniques Tool. Results We identified 36 eligible studies from 1984 citations in our electronic search and a further 2 studies from hand-searching resulting in 38 studies that targeted physician behaviour to reduce unnecessary LBP imaging. The studies were conducted in 6 countries in primary (n = 31) or emergency care (n = 7) settings. Thirty-four studies were included in our BCT synthesis which found the most frequently used BCTs were ‘4.1 instruction on how to perform the behaviour’ (e.g. Active/passive guideline dissemination and/or educational seminars/workshops), followed by ‘9.1 credible source’, ‘2.2 feedback on behaviour’ (e.g. electronic feedback reports on physicians’ image ordering) and 7.1 prompts and cues (electronic decision support or hard-copy posters/booklets for the office). This review highlighted that the majority of studies used education and/or feedback on behaviour to target the domains of knowledge and in some cases also skills and beliefs about capabilities to bring about a change in LBP imaging behaviour. Additionally, we found there to be a growing use of electronic or hard copy reminders to target the domains of memory and environmental context and resources. Conclusions This is the first study to identify what BCTs have been used to target a reduction in physician image ordering behaviour. The majority of included studies lacked the use of theory to inform their intervention design and failed to target known physician-reported barriers to following LBP imaging guidelines.

Background CT Imaging is often requested for patients with low back pain (LBP) by their general practitioners. It is currently unknown what reasons are common for these referrals and if CT images are ordered according to guidelines in one province in Canada, which has high rates of CT imaging. The objective of this study is to categorise lumbar spine CT referrals into serious spinal pathology, radicular syndrome, and non-specific LBP and evaluate the appropriateness of CT imaging referrals from general practitioners for patients with LBP. Methods A retrospective medical record review of electronic health records was performed in one health region in Newfoundland and Labrador, Canada. Inclusion criteria were lumbar spine CT referrals ordered by general practitioners for adults ≥18 years, and performed between January 1st-December 31st, 2016. Each CT referral was identified from linked databases (Meditech and PACS). To the study authors’ knowledge, guidelines regarding when to refer patients with low back pain for CT imaging had not been actively disseminated to general practitioners or implemented at clinics/hospitals during this time period. Data were manually extracted and categorised into three groups: red flag conditions (judged to be an appropriate referral), radicular syndrome (judged be unclear appropriateness), or nonspecific LBP (determined to be inappropriate). Results Three thousand six hundred nine lumbar spine CTs were included from 2016. The mean age of participants was 54.7 (SD 14 years), with females comprising 54.6% of referrals. 1.9% of lumbar CT referrals were missing/unclear, 6.5% of CTs were ordered on a red-flag suspicion, 75.6% for radicular syndromes, and 16.0% for non-specific LBP; only 6.5% of referrals were clearly appropriate. Key information including patient history and clinical exams performed at appointment were often missing from referrals. Conclusion This audit found high proportions of inappropriate or questionable referrals for lumbar spine CT and many were missing information needed to categorise. Further research to understand the drivers of inappropriate imaging and cost to the healthcare system would be beneficial.

Background Behavior change interventions have the potential to have a transformative effect on the health of populations. Allied health professionals have a key role to play in delivering these interventions. However, traditionally undergraduate allied health professional programs have not had a behavior change focus. The aim of this study was to assess the effectiveness of a training program on sport and exercise science students’ knowledge, confidence and skills in the provision of behavior change support. Method A mixed method convergent design was used to address the research question. Fifteen sport and exercise science students took part in a training program consisting of seven 90-min weekly face to face group sessions. Student satisfaction with training methods was assessed. Pre-to-post training changes in students’ confidence and knowledge in the provision of behavior change support was evaluated. Delivery of behavior change support was assessed by an audio recorded role-play rated by an expert using the Health Care Climate Questionnaire, and an adapted version of the Communication Evaluation in Rehabilitation Tool. Students also completed a reflective assignment. Results Students were satisfied with the training. There were increases in students’ confidence and knowledge of certain behavior change components post-training but not behavior change techniques. Students delivered behavior change support in a broadly needs supportive manner. The reflective assignment showed that students found particular behavior change strategies difficult to implement. Conclusion It is feasible to train undergraduate students in particular components of behavior change support. Academic institutions should embed behavior change training into the allied health professional curriculum to ensure graduates are job ready with the knowledge, confidence and skills to support health related behavior change within the wider health system.

Background Reducing computed tomography (CT) examinations of the lumbar spine is one of Choosing Wisely Canada's initial top 10 recommendations. This study's objective was to report the age- and-sex standardized rates of lumbar spine CT ordered by family physicians in 1 health region in Newfoundland and Labrador. Methods We conducted a retrospective study using local health data from Meditech, an electronic health record system, from 2013 to 2016 for the Eastern Health Region of Newfoundland and Labrador, the largest health region in the province. Records were included if the referral was for an adult aged 20 years or more, and CT was ordered by a family physician. Lumbar spine CT rates were contextualized with age- and sex-stratified estimates. Population estimates were provided by the Newfoundland and Labrador Centre for Health Information to calculate age- and sex-standardized rates per 100 000 people. We calculated rate ratios to test for statistical significance in differences in rates between years. Results A total of 14 370 records were examined. The age- and sex-standardized rates of lumbar spine CT per 100 000 were 1225 in 2013, 1393 in 2014, 1556 in 2015 and 1395 in 2016. The rate ratio was 1.137 (95% confidence interval [CI] 1.084-1.194) for the comparison between 2014 and 2013, 1.117 (95% CI 1.067-1.169) between 2015 and 2014, and 0.896 (95% CI 0.857-0.938) between 2016 and 2015. Interpretation The age- and sex-standardized rates suggest that there was a steady rate of lumbar spine CT examinations being ordered by family physicians in Newfoundland and Labrador in 2013-2016. Although all rate ratios were statistically significant, the magnitude of the difference between years is likely not clinically relevant. These rates are important because they serve as a benchmark for future initiatives to reduce unnecessary referrals for lumbar spine CT.

International clinical practice guidelines for low back pain (LBP) contain consistent recommendations including universal provision of information and advice to remain active, discouraging routine referral for imaging, and limited prescription of opioids. This systematic review describes usual care provided by first-contact physicians to patients with LBP. Studies that reported the assessments and care provided to people with LBP in family practice and emergency departments (EDs) from January 2000 to May 2019 were identified by searches of PubMed, EMBASE, and CINAHL. Study quality was assessed with reference to representativeness of samples, potential misclassification of patients, potential misclassification of outcomes, inconsistent data and precision of the estimate, and the findings of high-quality studies were prioritized in the data synthesis. We included 26 studies that reported data from almost 195,000 patients: 18 from family practice, and 8 from EDs. Less than 20% of patients with LBP received evidence-based information and advice from their family practitioner. Around 1 in 4 patients with LBP received referral for imaging in family practice and 1 in 3 in EDs. Up to 30% of patients with LBP were prescribed opioids in family practice and up to 60% in EDs. Large numbers of patients who saw a physician for LBP received care that is inconsistent with evidence-based clinical practice guidelines. Usual care included overuse of imaging and opioid prescription and underuse of advice and information. Suboptimal care may contribute to the massive burden of the condition worldwide.

Background The champion model is increasingly being adopted to improve uptake of guideline-based care in long-term care (LTC). Studies suggest that an on-site champion may improve the quality of care residents’ health outcomes. This review assessed the effectiveness of the champion on staff adherence to guidelines and subsequent resident outcomes in LTC homes. Method This was a systematic review and meta-analyses of randomised controlled trials. Eligible studies included residents aged 65 or over and nursing staff in LTC homes where there was a stand-alone or multi-component intervention that used a champion to improve staff adherence to guidelines and resident outcomes. The measured outcomes included staff adherence to guidelines, resident health outcomes, quality of life, adverse events, satisfaction with care, or resource use. Study quality was assessed with the Cochrane Risk of Bias tool; evidence certainty was assessed using the GRADE approach. Results After screening 4367 citations, we identified 12 articles that included the results of 1 RCT and 11 cluster-RCTs. All included papers evaluated the effects of a champion as part of a multicomponent intervention. We found low certainty evidence that champions as part of multicomponent interventions may improve staff adherence to guidelines. Effect sizes varied in magnitude across studies including unadjusted risk differences (RD) of 4.1% [95% CI: − 3%, 9%] to 44.8% [95% CI: 32%, 61%] for improving pressure ulcer prevention in a bed and a chair, respectively, RD of 44% [95% CI: 17%, 71%] for improving depression identification and RD of 21% [95% CI: 12%, 30%] for improving function-focused care to residents. Conclusion Champions may improve staff adherence to evidence-based guidelines in LTC homes. However, methodological issues and poor reporting creates uncertainty around these findings. It is premature to recommend the widespread use of champions to improve uptake of guideline-based care in LTC without further study of the champion role and its impact on cost.

Purpose: The purpose of this study was to determine current physiotherapy practice for managing chronic low back pain (LBP). Method: We administered a cross-sectional survey to all physiotherapists working in Eastern Health (EH) Regional Health Authority, Newfoundland and Labrador, by email. To ascertain how physiotherapists assessed and treated patients with LBP, the survey included multiple-choice and open-ended questions, along with case vignettes. We explored the respondents’ confidence about implementing all aspects of guideline-based care, as well as their use of treatment outcome measures. Results: A total of 76 physiotherapists responded to the survey (84% response rate); 56 (74%) reported that they treated patients with LBP as part of their regular practice. More than half had managed LBP for more than 10 years. The most frequently used treatments were self-management advice, followed by home and supervised exercise. The majority of respondents lacked confidence about implementing cognitive–behavioural treatment techniques. The Numeric Pain Rating Scale was the most commonly used outcome measure; disability outcome measures were not frequently used. Conclusions: The majority of LBP management in EH aligns with guideline recommendations. Increased uptake of guidelines recommending assessment and management of LBP using a bio-psychosocial approach will require training and support.

Background Imaging for low back pain is widely regarded as a target for efforts to reduce low-value care. Objective We aimed to estimate the prevalence of the overuse and underuse of lumbar imaging in patients presenting with low back pain to the emergency department (ED). Methods This was a retrospective chart review study of five public hospital EDs in Sydney, Australia, in 2019–20. We reviewed the clinical charts of consecutive adult patients who presented with a complaint of low back pain and extracted clinical features relevant to a decision to request lumbar imaging. We estimated the proportion of encounters where a decision to request lumbar imaging was inappropriate (overuse) or where a clinician did not request an appropriate and informative lumbar imaging test when indicated (underuse). Results Six hundred and forty-nine patients presented with a complaint of low back pain, of which 158 (24.3%) were referred for imaging. Seventy-nine (12.2%) had a combination of features suggesting that lumbar imaging was indicated according to clinical guidelines. The prevalence of overuse and underuse of lumbar imaging was 8.8% (57 of 649 cases, 95% CI 6.8–11.2%) and 4.3% (28 of 649 cases, 95% CI 3.0–6.1%), respectively. Thirteen cases were classified as underuse because the patients were referred for uninformative imaging modalities (e.g. referred for radiography for suspected cauda equina syndrome). Conclusion In this study of emergency care, there was evidence of not only overuse of lumbar imaging but also underuse through failure to request lumbar imaging when indicated or referral for an uninformative imaging modality. These three issues seem more important targets for quality improvement than solely focusing on overuse.

Background Low back pain (LBP) is one of the most common reasons for seeking health care and is costly to the health care system. Recent evidence has shown that LBP care provided by many providers is divergent from guidelines and one reason may be patient’s beliefs and expectations about treatment. Thus, examining the nature of patient beliefs and expectations regarding low back pain treatment will help coordinate efforts to improve consistency and quality of care. Methods This study was a cross-sectional population-based survey of adults living in Newfoundland, Canada. The survey included demographic information (e.g. age, gender, back pain status and care seeking behaviors) and assessed outcomes related to beliefs about the inevitable consequences of back pain with the validated back beliefs questionnaire as well as six additional questions relating beliefs about imaging, physical activity and medication. Surveys were mailed to 3000 households in July–August 2018 and responses collected until September 30th, 2018. Results Fout hundred twenty-eight surveys were returned (mean age 55 years (SD 14.6), 66% female, 90% had experienced an episode of LBP). The mean Back Beliefs Questionnaire score was 27.3 (SD 7.2), suggesting that people perceive back pain to have inevitable negative consequences. Large proportions of respondents held the following beliefs that are contrary to best available evidence: (i) having back pain means you will always have weakness in your back (49.3%), (ii) it will get progressively worse (48.0%), (iii) resting is good (41.4%) and (iv) x-rays or scans are necessary to get the best medical care for LBP (54.2%). Conclusions A high proportion of the public believe LBP to have inevitable negative consequences and hold incorrect beliefs about diagnosis and management options, which is similar to findings from other countries. This presents challenges for clinicians and suggests that considering how to influence beliefs about LBP in the broader community could have value. Given the high prevalence of LBP and that many will consult a range of healthcare professionals, future efforts could consider using broad reaching public health campaigns that target patients, policy makers and all relevant health providers with specific content to change commonly held unhelpful beliefs.

This article describes two patient advisory councils (PACs) in Canada in order to contribute to the limited evidence base on how they might facilitate patient engagement in health research. Specifically, members of PACs from Newfoundland and Labrador and Alberta describe their councils’ governance structure, primary functions, creation and composition, and recount specific research-related activities with which they have been involved. Key challenges of these councils and facilitators of their use are also presented. Finally, members from both councils recount lessons learned and offer suggestions for others interested in advisory councils as a mechanism for patient engagement in any health research project. Members believe patient engagement can result in better quality research and encourage decision makers and researchers to utilize patients’ valuable input to inform health system changes and drive priorities at a policy level.

Background Low back pain (LBP) rarely requires routine imaging of the lumbar spine in the primary care setting, as serious spinal pathology is rare. Despite evidence-based clinical practice guidelines recommending delaying imaging in the absence of red flags, chiropractors commonly order imaging outside of these guidelines. The purpose of this study was to survey chiropractors to determine the level of knowledge, adherence to, and beliefs about, clinical practice guidelines related to the use of lumbar radiography for LBP in Newfoundland and Labrador (NL), Canada. Methods A cross-sectional survey of chiropractors in NL (n = 69) was conducted between May and June 2018, including questions on demographics, awareness of radiographic guidelines, and beliefs about radiographs for LBP. We assessed behavioural simulation using clinical vignettes to determine levels of adherence to LBP guideline recommendations. Results The response rate was 77% (n = 53). Half of the participants stated they were aware of current radiographic guideline recommendations, and one quarter of participants indicated they did not use guidelines to inform clinical decisions. The majority of participants agreed that x-rays of the lumbar spine are useful for patients with suspected pathology, are indicated when a patient is non-responsive to 4 weeks of conservative treatment for LBP, and when there are neurological signs associated with LBP. However, a small proportion indicated that there is a role for full spine x-rays (~ 21%), x-rays to evaluate patients with acute LBP (~ 13%), and that patient expectations play a role in decision making (4%). Adherence rate to radiographic guidelines measured using clinical vignettes was 75%. Conclusions While many chiropractors in this sample reported being unsure of specific radiographic guidelines, the majority of respondents adhered to guideline recommendations measured using clinical vignettes. Nonetheless, a small proportion still hold beliefs about radiographs for LBP that are discordant with current radiographic guidelines. Future research should aim to determine barriers to guideline uptake in this population in order to design and evaluate tailored knowledge translation strategies to reduce unnecessary LBP imaging.

In many countries, there is a large amount of public money spent on health care. Some patient tests and treatments are not only unnecessary but also may be harmful, leading health researchers to look for the most effective interventions to change physician behaviour. The purpose of this chapter is to describe some of the interventions used to modify physician behaviour and highlight their challenges observed in a Canadian provincial context. We begin with a brief description of the increasing interest in behaviour change interventions in recent years and their theoretical basis. We then describe several interventions used to change physician behaviour ranging from nudges to choice restriction and the available evidence on their effectiveness. We provide examples of interventions and their challenges as we've experienced them in our research program, Quality of Care NL. We conclude with a summary of what the evidence tells us about interventions to change physicians' behaviours.

Objectives 1) Evaluate implementation of the Back Skills Training (BeST) programme, a group cognitive behavioural approach for patients with low back pain (LBP) developed for a clinical trial, into the National Health Service (NHS) in the United Kingdom; 2) Compare patient outcomes with the BeST Trial results. Design Two stage observational cohort implementation study. Participants Stage 1: NHS Clinicians enrolled in BeST online training. Stage 2: Patients with LBP attending NHS physiotherapy departments and enrolled in the BeST programme. Intervention An online training and implementation programme. Outcomes Stage 1: LBP attitudes and beliefs, self-rated competence, intention and actual implementation were collected before, immediately, 4- and 12-months post-training. Stage 2: Patients rated pain, function, recovery and satisfaction before and up to one year after attending the BeST programme. Results Stage 1: 1324 clinicians (157 NHS Trusts) enrolled in the training; 586 (44%) clinicians (101 NHS Trusts) completed training; 443/586 (76%) clinicians provided post-training data; 253/443 (57%) clinicians intended to implement the programme; 148/381 (39%) clinicians (54 NHS Trusts) provided follow-up data; 49/148 (33.1%) clinicians (27 NHS Trusts) implemented the programme. Attitudes and beliefs shifted towards a biopsychosocial model post-training. Stage 2: 923 patients were enrolled. Patients reported improvements in function (mean change: 1.55; 95%CI: 1.25, 1.86) and pain (−0.84; −1.1, −0.58) at follow-up. The majority rated themselves improved and satisfied with the programme. Conclusion Online training had good reach into NHS Trusts although, not everyone went onto implement the programme. Improvements in function that were consistent with the original trial were demonstrated.

IntroductionLow back pain accounts for more disability than any other musculoskeletal condition and is associated with severe economic burden. Patients commonly present with negative beliefs about low back pain and this can have detrimental effects on their health outcomes. Providing evidence-based, patient-centred education that meets patient needs could help address these negative beliefs and alleviate the substantial low back pain burden. The primary aim of this review is to investigate the effectiveness of patient education materials on immediate process, clinical and health system outcomes.Methods and analysisThe search strategy was developed in collaboration with a librarian and systematic searches will be performed in MEDLINE, EMBASE, CINAHL, PsycINFO and SPORTDiscus. We will also search trial registries and grey literature through the OpenGrey database. Study selection will include a title and abstract scan and full-text review by two authors. Only randomised controlled trials will be included in this review. Trials must include patients with low back pain or sciatica and investigate educational interventions with at least one of the following contrasts: (1) education alone versus no intervention; (2) education alone versus another intervention; (3) education in addition to another intervention versus the same intervention with no education. Data extraction, risk of bias and grading of the quality of evidence will be performed independently by two reviewers. Risk of bias will be assessed using the PEDro scale, and the quality of evidence will be assessed with the Grades of Recommendation, Assessment, Development and Evaluation approach. A random-effects model will be used for each contrast, and results will be pooled if the participants, interventions, and outcomes are homogeneous. If heterogeneity is high (I2>75%), we will evaluate the magnitude and direction of the differences in effect sizes across studies to determine if it remains reasonable to pool the results. Analyses of acute and subacute low back pain (less than 12 weeks duration) will be performed separately from chronic low back pain (12 weeks or greater duration). Likewise, analyses of short-term (less than 6 months) and long-term (6 months or greater) follow-up will be performed separately. Subgroup analyses will be performed on non-specific low back pain, sciatica and mixed populations.Ethics and disseminationEthical approval is not required for this review. This study, along with its results, will be published in a peer-reviewed journal.

Background The self-management of osteoarthritis (OA) and low back pain (LBP) through activity and skills (SOLAS) theory-driven group-based complex intervention was developed primarily for the evaluation of its acceptability to patients and physiotherapists and the feasibility of trial procedures, to inform the potential for a definitive trial. Methods This assessor-blinded multicentre two-arm parallel cluster randomised controlled feasibility trial compared the SOLAS intervention to usual individual physiotherapy (UP; pragmatic control group). Patients with OA of the hip, knee, lumbar spine and/or chronic LBP were recruited in primary care physiotherapy clinics (i.e. clusters) in Dublin, Ireland, between September 2014 and November 2015. The primary feasibility objectives were evaluated using quantitative methods and individual telephone interviews with purposive samples of participants and physiotherapists. A range of secondary outcomes were collected at baseline, 6 weeks (behaviour change only), 2 months and 6 months to explore the preliminary effects of the intervention. Analysis was by intention-to-treat according to participants’ cluster allocation and involved descriptive analysis of the quantitative data and inductive thematic analysis of the qualitative interviews. A linear mixed model was used to contrast change over time in participant secondary outcomes between treatment arms, while adjusting for study waves and clusters. Results Fourteen clusters were recruited (7 per trial arm), each cluster participated in two waves of recruitment, with the average cluster size below the target of six participants (intervention: mean (SD) = 4.92 (1.31), range 2–7; UP: mean (SD) = 5.08 (2.43), range 1–9). One hundred twenty participants (83.3% of n = 144 expected) were recruited (intervention n = 59; UP n = 61), with follow-up data obtained from 80.8% (n = 97) at 6 weeks, 84.2% (n = 101) at 2 months and 71.7% (n = 86) at 6 months. Most participants received treatment as allocated (intervention n = 49; UP n = 54). The qualitative interviews (12 participants; 10 physiotherapists (PTs) found the intervention and trial procedures acceptable and appropriate, with minimal feasible adaptations required. Linear mixed methods showed improvements in most secondary outcomes at 2 and 6 months with small between-group effects. Conclusions While the SOLAS intervention and trial procedures were acceptable to participants and PTs, the recruitment of enough participants is the biggest obstacle to a definitive trial.

Choosing Wisely (CW) campaigns globally have focused attention on the need to reduce low-value care, which can represent up to 30% of the costs of healthcare. Despite early enthusiasm for the CW initiative, few large-scale changes in rates of low-value care have been reported since the launch of these campaigns. Recent commentaries suggest that the focus of the campaign should be on implementation of evidence-based strategies to effectively reduce low-value care. This paper describes the Choosing Wisely De-Implementation Framework (CWDIF), a novel framework that builds on previous work in the field of implementation science and proposes a comprehensive approach to systematically reduce low-value care in both hospital and community settings and advance the science of de-implementation.The CWDIF consists of five phases: Phase 0, identification of potential areas of low-value healthcare; Phase 1, identification of local priorities for implementation of CW recommendations; Phase 2, identification of barriers to implementing CW recommendations and potential interventions to overcome these; Phase 3, rigorous evaluations of CW implementation programmes; Phase 4, spread of effective CW implementation programmes. We provide a worked example of applying the CWDIF to develop and evaluate an implementation programme to reduce unnecessary preoperative testing in healthy patients undergoing low-risk surgeries and to further develop the evidence base to reduce low-value care.

Background: Changing population demographics have led to an increasing number of functionally dependent older people who require care and medical treatment. In many countries, government policy aims to shift resources into the community from institutional care settings with the expectation that this will reduce costs and improve the quality of care compared. Objectives: To assess the effects of long‐term home or foster home care versus institutional care for functionally dependent older people. Search methods: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Library, MEDLINE, Embase, CINAHL, and two trials registers to November 2015. Selection criteria: We included randomised and non‐randomised trials, controlled before‐after studies and interrupted time series studies complying with the EPOC study design criteria and comparing the effects of long‐term home care versus institutional care for functionally dependent older people. Data collection and analysis: Two reviewers independently extracted data and assessed the risk of bias of each included study. We reported the results narratively, as the substantial heterogeneity across studies meant that meta‐analysis was not appropriate. Main results: We included 10 studies involving 16,377 participants, all of which were conducted in high income countries. Included studies compared community‐based care with institutional care (care homes). The sample size ranged from 98 to 11,803 (median N = 204). There was substantial heterogeneity in the healthcare context, interventions studied, and outcomes assessed. One study was a randomised trial (N = 112); other included studies used designs that had potential for bias, particularly due lack of randomisation, baseline imbalances, and non‐blinded outcome assessment. Most studies did not select (or exclude) participants for any specific disease state, with the exception of one study that only included patients if they had a stroke. All studies had methodological limitations, so readers should interpret results with caution. It is uncertain whether long‐term home care compared to nursing home care decreases mortality risk (2 studies, N = 314, very‐low certainty evidence). Estimates ranged from a nearly three‐fold increased risk of mortality in the homecare group (risk ratio (RR) 2.89, 95% confidence interval (CI) 1.57 to 5.32) to a 62% relative reduction (RR 0.38, 95% CI 0.17 to 0.61). We did not pool data due to the high degree of heterogeneity (I2 = 94%). It is uncertain whether the intervention has a beneficial effect on physical function, as the certainty of evidence is very low (5 studies, N = 1295). Two studies reported that participants who received long‐term home care had improved activities of daily living compared to those in a nursing home, whereas a third study reported that all participants performed equally on physical function. It is uncertain whether long‐term home care improves happiness compared to nursing home care (RR 1.97, 95% CI 1.27 to 3.04) or general satisfaction because the certainty of evidence was very low (2 studies, N = 114). The extent to which long‐term home care was associated to more or fewer adverse health outcomes than nursing home care was not reported. It is uncertain whether long‐term home care compared to nursing home care decreases the risk of hospital admission (very low‐certainty evidence, N = 14,853). RR estimates ranged from 2.75 (95% CI 2.59 to 2.92), showing an increased risk for those receiving care at home, to 0.82 (95% CI 0.72 to 0.93), showing a slightly reduced risk for the same group. We did not pool data due to the high degree of heterogeneity (I2 = 99%). Authors' conclusions: There are insufficient high‐quality published data to support any particular model of care for functionally dependent older people. Community‐based care was not consistently beneficial across all the included studies; there were some data suggesting that community‐based care may be associated with improved quality of life and physical function compared to institutional care. However, community alternatives to institutional care may be associated with increased risk of hospitalisation. Future studies should assess healthcare utilisation, perform economic analysis, and consider caregiver burden.

The purpose of this study was to test the feasibility of a theory-based self-regulation intervention to increase older adolescents' leisure time physical activity (LTPA) behavior. Forty-nine adolescents (M = 15.78 years; SD = 0.52; 31% female) from two schools agreed to participate. Participants were randomly assigned to the experimental or control arm at the school level. The experimental group (n = 24) underwent a brief self-regulation intervention for six weeks. The control group (n = 25) continued with standard classes. Intervention fidelity data was collected to assess feasibility. Outcome measures included self-reported LTPA behavior and self-regulation technique use. Intervention sessions were delivered as intended, participant attendance was high and compliance with intervention content was acceptable. The experimental group reported higher levels of LTPA behavior eight weeks post-intervention and increased use of self-regulation techniques. A brief theory-based self-regulation intervention delivered in a school-setting appears feasible and may increase LTPA behavior and self-regulation in adolescents.

Self-management interventions for persistent low back pain (LBP) promote active involvement of the patient in managing their condition. Such interventions can be characterised as behaviour change interventions, in that they are designed to help the patient learn and adopt a set of health behaviours that they can use in everyday life to benefit their condition by reducing or managing their symptoms. Self-management interventions are recommended in several key guidelines for the treatment of persistent LBP, but the evidence for the effectiveness of these types of interventions is inconclusive. In this article, we discuss the existing literature within self-management interventions for persistent LBP and make suggestions for how research in this area can be improved, specifically addressing areas where evidence is currently lacking. Existing definitions of self-management are examined, and the importance of the choice of an underlying theory and appropriate outcome measures are discussed.

Background Clinical guidelines exhort clinicians to encourage patients to improve their health behaviours. However, most offer little support on how to have these conversations in practice. Clinicians fear that health behaviour change talk will create interactional difficulties and discomfort for both clinician and patient. This review aims to identify how healthcare professionals can best communicate with patients about health behaviour change (HBC). Methods We included studies which used conversation analysis or discourse analysis to study recorded interactions between healthcare professionals and patients. We followed an aggregative thematic synthesis approach. This involved line-by-line coding of the results and discussion sections of included studies, and the inductive development and hierarchical grouping of descriptive themes. Top-level themes were organised to reflect their conversational positioning. Results Of the 17,562 studies identified through systematic searching, ten papers were included. Analysis resulted in 10 top-level descriptive themes grouped into three domains: initiating; carrying out; and closing health behaviour change talk. Of three methods of initiation, two facilitated further discussion, and one was associated with outright resistance. Of two methods of conducting behaviour change talk, one was associated with only minimal patient responses. One way of closing was identified, and patients did not seem to respond to this positively. Results demonstrated a series of specific conversational practices which clinicians use when talking about HBC, and how patients respond to these. Our results largely complemented clinical guidelines, providing further detail on how they can best be delivered in practice. However, one recommended practice - linking a patient’s health concerns and their health behaviours - was shown to receive variable responses and to often generate resistance displays. Conclusions Health behaviour change talk is smoothly initiated, conducted, and terminated by clinicians and this rarely causes interactional difficulty. However, initiating conversations by linking a person’s current health concern with their health behaviour can lead to resistance to advice, while other strategies such as capitalising on patient initiated discussions, or collaborating through question-answer sequences, may be well received.

Background Adoption of low back pain guidelines is a well-documented problem. Information to guide the development of behaviour change interventions is needed. The review is the first to synthesise the evidence regarding physicians’ barriers to providing evidence-based care for LBP using the Theoretical Domains Framework (TDF). Using the TDF allowed us to map specific physician-reported barriers to individual guideline recommendations. Therefore, the results can provide direction to future interventions to increase physician compliance with evidence-based care for LBP. Methods We searched the literature for qualitative studies from inception to July 2018. Two authors independently screened titles, abstracts, and full texts for eligibility and extracted data on study characteristics, reporting quality, and methodological rigour. Guided by a TDF coding manual, two reviewers independently coded the individual study themes using NVivo. After coding, we assessed confidence in the findings using the GRADE-CERQual approach. Results Fourteen studies (n = 318 physicians) from 9 countries reported barriers to adopting one of the 5 guideline-recommended behaviours regarding in-clinic diagnostic assessments (9 studies, n = 198), advice on activity (7 studies, n = 194), medication prescription (2 studies, n = 39), imaging referrals (11 studies, n = 270), and treatment/specialist referrals (8 studies, n = 193). Imaging behaviour is influenced by (1) social influence—from patients requesting an image or wanting a diagnosis (n = 252, 9 studies), (2) beliefs about consequence—physicians believe that providing a scan will reassure patients (n = 175, 6 studies), and (3) environmental context and resources—physicians report a lack of time to have a conversation with patients about diagnosis and why a scan is not needed (n = 179, 6 studies). Referrals to conservative care is influenced by environmental context and resources—long wait-times or a complete lack of access to adjunct services prevented physicians from referring to these services (n = 82, 5 studies). Conclusions Physicians face numerous barriers to providing evidence-based LBP care which we have mapped onto 7 TDF domains. Two to five TDF domains are involved in determining physician behaviour, confirming the complexity of this problem. This is important as interventions often target a single domain where multiple domains are involved. Interventions designed to address all the domains involved while considering context-specific factors may prove most successful in increasing guideline adoption.

What you need to know The past two decades have seen a paradigm shift in the way we use imaging when managing low back pain (LBP). Imaging was once a routine part of the diagnostic workup for most cases of LBP. Evidence now indicates that imaging is useful only in the small subgroup of patients for whom there is suspicion of red flag conditions. These conditions include cancer, infection, inflammatory disease, fracture, and severe neurological deficits—which together account for only 5-10% of LBP presentations in primary care.1 For the remaining 90-95% of LBP cases (called non-specific or uncomplicated LBP), imaging will not guide management and can cause more harm than benefit. International guidelines2 and “Choosing Wisely” campaigns now encourage a diagnostic triage approach to identify those patients who require imaging (box 1). Given these advances in knowledge, imaging rates for LBP should be decreasing, but recent systematic reviews show the opposite, reporting that imaging has increased over the past 20 years3 and that at least a third of all images are unnessary.4 Box 1 ### “Choosing Wisely” statements from different countries related to avoiding the use of routine imaging for low back painRETURN TO TEXT

Objectives There is evidence to support the effectiveness of tai chi for reducing pain-related symptoms across multiple musculoskeletal conditions, however, the mechanism(s) are unclear. This study explores the role of pain-catastrophising as a possible mediator in the relationship between practising tai chi and back pain symptoms. Design Exploratory mediation analyses using a Baron and Kenny approach and bootstrapping methods were employed as a secondary analysis of data from a previously published randomised controlled trial. Setting Adults with persistent low back pain were recruited via community advertisement in Sydney, NSW, Australia. Interventions A 10-week tai chi intervention and a wait-list control. Main outcome measures Patients completed self-assessments of pain intensity and bothersomeness using 0–10 numerical rating scales, disability using the Roland Morris Disability Questionnaire and pain catastrophising using the Pain Coping Strategies Questionnaire pre and post intervention. Results The results suggest partial mediation, by which a reduction in catastrophising explained approximately 1/3 of the effect on pain intensity and bothersomeness and 2/3 of the effect on disability. Conclusion As the first known mediation analysis of tai chi for reducing low back pain-symptoms, it provides initial evidence that it may do so by having an effect on cognitive appraisal outcomes such as pain-catastrophising and information for choosing appropriate process measures for future studies. As tai chi is growing in popularity as an alternative treatment for patients with chronic musculoskeletal conditions, it is important to gain a better understanding of how it might work using confirmatory mediation analysis alongside future RCTs.

Background Since 2000, guidelines have been consistent in recommending when diagnostic imaging for low back pain should be obtained to ensure patient safety and reduce unnecessary tests. This systematic review and meta-analysis was conducted to determine the pooled proportion of CT and x-ray imaging of the lumbar spine that were considered appropriate in primary and emergency care. Methods Pubmed, CINAHL, The Cochrane Database of Systematic Reviews and Embase were searched for synonyms of “low back pain”, “guidelines”, and “adherence” that were published after 2000. Titles, abstracts, and full texts were reviewed for inclusion with forward and backward tracking on included studies. Included studies had data extracted and synthesized. Risk of bias was performed on all studies, and GRADE was performed on included studies that provided data on CT and x-ray separately. A random effect, single proportion meta-analysis model was used. Results Six studies were included in the descriptive synthesis, and 5 studies included in the meta-analysis. Five of the 6 studies assessed appropriateness of x-rays; two of the six studies assessed appropriateness of CTs. The pooled estimate for appropriateness of x-rays was 43% (95% CI: 30%, 56%) and the pooled estimate for appropriateness of CTs was 54% (95% CI: 51%, 58%). Studies did not report adequate information to fulfill the RECORD checklist (reporting guidelines for research using observational data). Risk of bias was high in 4 studies, moderate in one, and low in one. GRADE for x-ray appropriateness was low-quality and for CT appropriateness was very-low-quality. Conclusion While this study determined a pooled proportion of appropriateness for both x-ray and CT imaging for low back pain, there is limited confidence in these numbers due to the downgrading of the evidence using GRADE. Further research on this topic is needed to inform our understanding of x-ray and CT appropriateness in order to improve healthcare systems and decrease patient harms.

Background By adaptation of the face-to-face physiotherapist-training program previously used in the Self-management of Osteoarthritis and Low back pain through Activity and Skills (SOLAS) feasibility trial, an asynchronous, interactive, Web-based, e-learning training program (E-SOLAS) underpinned by behavior and learning theories was developed. Objective This study investigated the effect of the E-SOLAS training program on relevant outcomes of effective training and implementation. Methods Thirteen physiotherapists from across Ireland were trained via E-SOLAS by using mixed methods, and seven physiotherapists progressed to implementation of the 6-week group-based SOLAS intervention. The effectiveness of E-SOLAS was evaluated using the Kirkpatrick model at the levels of reaction (physiotherapist engagement and satisfaction with E-SOLAS training methods and content), learning (pre- to posttraining changes in physiotherapists’ confidence and knowledge in delivering SOLAS content and self-determination theory-based communication strategies, administered via a SurveyMonkey questionnaire), and behavior (fidelity to delivery of SOLAS content using physiotherapist-completed weekly checklists). During implementation, five physiotherapists audio recorded delivery of one class, and the communication between physiotherapists and clients was assessed using the Health Care Climate Questionnaire (HCCQ), the Controlling Coach Behaviour Scale (CCBS), and an intervention-specific measure (ISM; 7-point Likert scale). A range of implementation outcomes were evaluated during training and delivery (ie, acceptability, appropriateness, feasibility, fidelity, and sustainability of E-SOLAS) using a posttraining feedback questionnaire and individual semistructured telephone interviews. Results With regard to their reaction, physiotherapists (n=13) were very satisfied with E-SOLAS posttraining (median 5.0; interquartile range 1.0; min-max 4.0-5.0) and completed training within 3-4 weeks. With regard to learning, there were significant increases in physiotherapists’ confidence and knowledge in delivery of all SOLAS intervention components (P.05). In terms of behavior, physiotherapists delivered SOLAS in a needs supportive manner (HCCQ: median 5.2, interquartile range 1.3, min-max 3.7-5.8; CCBS: median 6.6, interquartile range 1.0, min-max 5.6-7.0; ISM: median 4.5, interquartile range 1.2, min-max 2.8-4.8). Fidelity scores were high for SOLAS content delivery (total %mean fidelity score 93.5%; SD 4.9%). The posttraining questionnaire and postdelivery qualitative interviews showed that physiotherapists found E-SOLAS acceptable, appropriate, feasible, and sustainable within primary care services to support the implementation of the SOLAS intervention. Conclusions This study provides preliminary evidence of the effectiveness, acceptability, and feasibility of an e-learning program to train physiotherapists to deliver a group-based self-management complex intervention in primary care settings, which is equivalent to face-to-face training outcomes and would support inclusion of physiotherapists in a definitive trial of SOLAS.

Purpose: Evidence has suggested that patients' expectations influence the clinical course when they present with low back pain (LBP). However, little empirical evidence has outlined the nature of these expectations. The aim of this study was to describe LBP patients' expectations of physiotherapy. Method: Seventy-nine adult patients who had LBP for more than 16 weeks and were referred for physiotherapy at two hospital physiotherapy departments in St. John's, Newfoundland and Labrador, were included. They filled out a questionnaire detailing their expectations of treatment. Results: Before treatment, more than 90% of patients expected a physical examination, tests or investigations, a diagnosis, reassurance and advice, and clear explanations of causation, symptom management, and benefits and risks of treatment. Approximately half hoped for a prescription or referral to a specialist, and about 60% hoped to discuss problems in their life. Conclusions: The findings of this study indicate that patients attend physiotherapy with clear expectations about what information should be provided. Most expected tests or investigations leading to diagnosis and an explanation of causation; this presents a challenge for clinicians, given the current understanding of LBP reflected in international practice guidelines. The fact that more than half of the patients wanted to discuss problems in their life points to the need for physiotherapists to consider LBP from a bio-psychosocial perspective.

Background Online training is growing in popularity and yet its effectiveness for training licensed health professionals (HCPs) in clinical interventions is not clear. We aimed to systematically review the literature on the effectiveness of online versus alternative training methods in clinical interventions for licensed Health Care Professionals (HCPs) on outcomes of knowledge acquisition, practical skills, clinical behaviour, self-efficacy and satisfaction. Methods Seven databases were searched for randomised controlled trials (RCTs) from January 2000 to June 2015. Two independent reviewers rated trial quality and extracted trial data. Comparative effects were summarised as standardised mean differences (SMD) and 95% confidence intervals. Pooled effect sizes were calculated using a random-effects model for three contrasts of online versus (i) interactive workshops (ii) taught lectures and (iii) written/electronic manuals. Results We included 14 studies with a total of 1089 participants. Most trials studied medical professionals, used a workshop or lecture comparison, were of high risk of bias and had small sample sizes (range 21-183). Using the GRADE approach, we found low quality evidence that there was no difference between online training and an interactive workshop for clinical behaviour SMD 0.12 (95% CI -0.13 to 0.37). We found very low quality evidence of no difference between online methods and both a workshop and lecture for knowledge (workshop: SMD 0.04 (95% CI -0.28 to 0.36); lecture: SMD 0.22 (95% CI: -0.08, 0.51)). Lastly, compared to a manual (n = 3/14), we found very low quality evidence that online methods were superior for knowledge SMD 0.99 (95% CI 0.02 to 1.96). There were too few studies to draw any conclusions on the effects of online training for practical skills, self-efficacy, and satisfaction across all contrasts. Conclusions It is likely that online methods may be as effective as alternative methods for training HCPs in clinical interventions for the outcomes of knowledge and clinical behaviour. However, the low quality of the evidence precludes drawing firm conclusions on the relative effectiveness of these training methods. Moreover, the confidence intervals around our effect sizes were large and could encompass important differences in effectiveness. More robust, adequately powered RCTs are needed.

Objective To examine the effects of communication skills training on physiotherapists' supportive behavior during clinical practice. Design Randomized trial. Setting Hospital outpatient physiotherapy clinics. Participants Physiotherapists (N=24) and patients (N=24) with chronic low back pain. Interventions Two hospital clinics were randomly assigned to the intervention arm. Physiotherapists (n=12) received 8 hours of communication skills training focused on supporting patients' psychological needs. Physiotherapists (n=12) from 2 other hospital clinics formed a waitlist control arm. Main Outcome Measures Verbal communication between each physiotherapist and a patient was recorded on an audiotape, and independent, blinded raters used the Health Care Climate Questionnaire to assess physiotherapists' needs-supportive behavior (primary outcome). Results Independent raters' Health Care Climate Questionnaire scores favored the intervention arm (Cohen's d=2.27; P

Objective To assess the effect of an intervention designed to enhance physiotherapists' communication skills on patients' adherence to recommendations regarding home-based rehabilitation for chronic low back pain. Design Cluster randomized controlled trial. Setting Publicly funded physiotherapy clinics. Participants A sample (N=308) of physiotherapists (n=53) and patients with chronic low back pain (n=255; 54% female patients; mean age, 45.3y). Interventions Patients received publicly funded individual physiotherapy care. In the control arm, care was delivered by a physiotherapist who had completed a 1-hour workshop on evidence-based chronic low back pain management. Patients in the experimental arm received care from physiotherapists who had also completed 8 hours of communication skills training. Main Outcome Measures (1) Patient-reported adherence to their physiotherapists' recommendations regarding home-based rehabilitation measured at 1, 4, 12, and 24 weeks after the initial treatment session. (2) Pain and pain-related function measured at baseline and at 4, 12, and 24 weeks. Results A linear mixed model analysis revealed that the experimental arm patients' ratings of adherence were higher than those of controls (overall mean difference, .41; 95% confidence interval, .10–.72; d =.28; P =.01). Moderation analyses revealed that men, regardless of the intervention, showed improvements in pain-related function over time. Only women in the experimental arm showed functional improvements; female controls showed little change in function over time. The Communication Style and Exercise Compliance in Physiotherapy intervention did not influence patients' pain, regardless of their sex. Conclusions Communication skills training for physiotherapists had short-term positive effects on patient adherence. This training may provide a motivational basis for behavior change and could be a useful component in complex interventions to promote adherence. Communication skills training may also improve some clinical outcomes for women, but not for men.

Purpose: To determine if physiotherapist-led cognitive-behavioural (CB) interventions are effective for low back pain (LBP) and described sufficiently for replication. Method: Randomised controlled trials (RCTs) of patients with LBP treated by physiotherapists using a CB intervention were included. Outcomes of disability, pain, and quality of life were assessed using the GRADE approach. Intervention reporting was assessed using the Template for Intervention Description and Replication. Results: Of 1898 titles, 5 RCTs (n = 1390) were identified. Compared to education and/or exercise interventions, we found high-quality evidence that CB had a greater effect (SMD; 95% CI) on reducing disability (−0.19; −0.32, −0.07), pain (−0.21; −0.33, −0.09); and moderate-quality evidence of little difference in quality of life (−0.06; −0.18 to 0.07). Sufficient information was provided on dose, setting, and provider; but not content and procedural information. Studies tended to report the type of CB component used (e.g., challenging unhelpful thoughts) with little detail on how it was operationalised. Moreover, access to treatment manuals, patient materials and provider training was lacking. Conclusions: With additional training, physiotherapists can deliver effective CB interventions. However, without training or resources, successful translation and implementation remains unlikely. Researchers should improve reporting of procedural information, provide relevant materials, and offer accessible provider training. Implications for RehabilitationPrevious reviews have established that traditional biomedical-based treatments (e.g., acupuncture, manual therapy, massage, and specific exercise programmes) that focus only on physical symptoms do provide short-term benefits but the sustained effect is questionable. A cognitive-behavioural (CB) approach includes techniques to target both physical and psychosocial symptoms related to pain and provides patients with long-lasting skills to manage these symptoms on their own. This combined method has been used in a variety of settings delivered by different health care professionals and has been shown to produce long-term effects on patient outcomes. What has been unclear is if these programmes are effective when delivered by physiotherapists in routine physiotherapy settings. Our study synthesises the evidence for this context.We have confirmed with high-quality evidence that with additional training, physiotherapists can deliver CB interventions that are effective for patients with back pain. Physiotherapists who are considering enhancing their treatment for patients with low back pain should consider undertaking some additional training in how to incorporate CB techniques into their practice to optimise treatment benefits and help patients receive long-lasting treatment effects.Importantly, our results indicate that using a CB approach, including a variety of CB techniques that could be easily adopted in a physical therapy setting, provides greater benefits for patient outcomes compared to brief education, exercise or physical techniques (such as manual therapy) alone. This provides further support that a combined treatment approach is likely better than one based on physical techniques alone.Notably, we identified a significant barrier to adopting any of these CB interventions in practice. This is because no study provided a description of the intervention or accessible training materials that would allow for accurate replication. Without access to provider training and/or resources, we cannot expect this evidence to be implemented in practice with optimal effects. Thus, we would urge physiotherapists to directly contact authors of the studies for more information on how to incorporate their interventions into their settings.

Objective: To determine whether the effect of the ‘Strengthening And stretching for Rheumatoid Arthritis of the Hand' (SARAH) exercise programme on hand function was mediated by changes in the proposed active ingredients: strength, dexterity, and/or range of motion. Methods: The SARAH intervention included exercises hypothesized to improve potential mediators of grip strength, pinch strength, wrist flexion, wrist extension, finger flexion, finger extension, thumb opposition, and dexterity, which would theoretically improve self-reported hand function. All variables were measured at baseline and at 4 and 12 months. Structural equation modelling was used to assess mediation on change in hand function via change in potential mediators. Results: Change in grip strength partially mediated change in hand function. Grip strength mediated 19.4% (95% confidence interval: 0.9% to 37.8%) of the treatment effect. Discussion: Improvements in grip strength at 4 months are likely to mediate improved hand function at 12 months. The role of joint mobility exercises is less clear and is likely influenced by the choice of measurement tools for both mobility and function outcomes. More robust measurements of wrist and hand mobility for patients with rheumatoid arthritis may be necessary to determine the relationship between this variable and self-reported hand function. Conclusion: Using a large trial dataset, we have demonstrated that techniques used to target grip strength are key active ingredients of the SARAH exercise programme and mediate its effect.

Background The uptake of clinical practice guidelines (CPGs) is inconsistent, despite their potential to improve the quality of health care and patient outcomes. Some guideline producers have addressed this problem by developing tools to encourage faster adoption of new guidelines. This review focuses on the effectiveness of tools developed and disseminated by guideline producers to improve the uptake of their CPGs. Objectives To evaluate the effectiveness of implementation tools developed and disseminated by guideline producers, which accompany or follow the publication of a CPG, to promote uptake. A secondary objective is to determine which approaches to guideline implementation are most effective. Search methods We searched the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL); NHS Economic Evaluation Database, HTA Database; MEDLINE and MEDLINE In-Process and other non-indexed citations; Embase; PsycINFO; CINAHL; Dissertations and Theses, ProQuest; Index to Theses; Science Citation Index Expanded, ISI Web of Knowledge; Conference Proceedings Citation Index - Science, ISI Web of Knowledge; Health Management Information Consortium (HMIC), and NHS Evidence up to February 2016. We also searched trials registers, reference lists of included studies and relevant websites. Selection criteria We included randomised controlled trials (RCTs) and cluster-RCTs, controlled before-and-after studies (CBAs) and interrupted time series (ITS) studies evaluating the effects of guideline implementation tools developed by recognised guideline producers to improve the uptake of their own guidelines. The guideline could target any clinical area. Data collection and analysis Two review authors independently extracted data and assessed the risk of bias of each included study using the Cochrane 'Risk of bias' criteria. We graded our confidence in the evidence using the approach recommended by the GRADE working group. The clinical conditions targeted and the implementation tools used were too heterogenous to combine data for meta-analysis. We report the median absolute risk difference (ARD) and interquartile range (IQR) for the main outcome of adherence to guidelines. Main results We included four cluster-RCTs that were conducted in the Netherlands, France, the USA and Canada. These studies evaluated the effects of tools developed by national guideline producers to implement their CPGs. The implementation tools evaluated targeted healthcare professionals; none targeted healthcare organisations or patients. One study used two short educational workshops tailored to barriers. In three studies the intervention consisted of the provision of paper-based educational materials, order forms or reminders, or both. The clinical condition, type of healthcare professional, and behaviour targeted by the CPG varied across studies. Two of the four included studies reported data on healthcare professionals' adherence to guidelines. A guideline tool developed by the producers of a guideline probably leads to increased adherence to the guidelines; median ARD (IQR) was 0.135 (0.115 and 0.159 for the two studies respectively) at an average four-week follow-up (moderate certainty evidence), which indicates a median 13.5% greater adherence to guidelines in the intervention group. Providing healthcare professionals with a tool to improve implementation of a guideline may lead to little or no difference in costs to the health service. Authors' conclusions Implementation tools developed by recognised guideline producers probably lead to improved healthcare professionals' adherence to guidelines in the management of non-specific low back pain and ordering thyroid-function tests. There are limited data on the relative costs of implementing these interventions.There are no studies evaluating the effectiveness of interventions targeting the organisation of care (e.g. benchmarking tools, costing templates, etc.), or for mass media interventions. We could not draw any conclusions about our second objective, the comparative effectiveness of implementation tools, due to the small number of studies, the heterogeneity between interventions, and the clinical conditions that were targeted.

OBJECTIVES:Our objectives were two-fold: (i) to describe physiotherapists' experiences of implementing a cognitive behavioural approach (CBA) for managing low back pain (LBP) after completing an extensive online training course (iBeST), and (ii) to identify how iBeST could be enhanced to support long-term implementation before scale up for widespread use. DESIGN:We conducted semi-structured interviews with 11 physiotherapists from six National Health Service departments in the Midlands, Oxfordshire and Derbyshire. Questions centred on (i) using iBeST to support implementation, (ii) what barriers they encountered to implementation and (iii) what of information or resources they required to support sustained implementation. Interviews were transcribed and thematically analysed using NVivo. Themes were categorised using the Theoretical Domains Framework (TDF). Evidence-based techniques were identified using the behaviour change technique taxonomy to target relevant TDF domains. RESULTS:Three themes emerged from interviews: anxieties about using a CBA, experiences of implementing a CBA, and sustainability for future implementation of a CBA. Themes crossed multiple TDF domains and indicated concerns with knowledge, beliefs about capabilities and consequences, social and professional roles, social influences, emotion, and environmental context and resources. We identified evidence-based strategies that may support sustainable implementation of a CBA for LBP in a physiotherapy setting. CONCLUSIONS:This study highlighted potential challenges for physiotherapists in the provision of evidence-based LBP care within the current UK NHS. Using the TDF provided the foundation to develop a tailored, evidence-based, implementation intervention to support long term use of a CBA by physiotherapists managing LBP within UK NHS outpatient departments.

Introduction International clinical guidelines consistently endorse the promotion of self-management (SM), including physical activity for patients with chronic low back pain (CLBP) and osteoarthritis (OA). Patients frequently receive individual treatment and advice to self-manage from physiotherapists in primary care, but the successful implementation of a clinical and cost-effective group SM programme is a key priority for health service managers in Ireland to maximise long-term outcomes and efficient use of limited and costly resources. Methods/analysis This protocol describes an assessor-blinded cluster randomised controlled feasibility trial of a group-based education and exercise intervention underpinned by self-determination theory designed to support an increase in SM behaviour in patients with CLBP and OA in primary care physiotherapy. The primary care clinic will be the unit of randomisation (cluster), with each clinic randomised to 1 of 2 groups providing the Self-management of Osteoarthritis and Low back pain through Activity and Skills (SOLAS) intervention or usual individual physiotherapy. Patients are followed up at 6 weeks, 2 and 6 months. The primary outcomes are the (1) acceptability and demand of the intervention to patients and physiotherapists, (2) feasibility and optimal study design/procedures and sample size for a definitive trial. Secondary outcomes include exploratory analyses of: point estimates, 95% CIs, change scores and effect sizes in physical function, pain and disability outcomes; process of change in target SM behaviours and selected mediators; and the cost of the intervention to inform a definitive trial. Ethics/dissemination This feasibility trial protocol was approved by the UCD Human Research Ethics—Sciences Committee (LS-13-54 Currie-Hurley) and research access has been granted by the Health Services Executive Primary Care Research Committee in January 2014. The study findings will be disseminated to the research, clinical and health service communities through publication in peer-reviewed journals, presentation at national and international academic and clinical conferences. Trial registration number ISRCTN 49875385; Pre-results.

Background The Medical Research Council framework provides a useful general approach to designing and evaluating complex interventions, but does not provide detailed guidance on how to do this and there is little evidence of how this framework is applied in practice. This study describes the use of intervention mapping (IM) in the design of a theory-driven, group-based complex intervention to support self-management (SM) of patients with osteoarthritis (OA) and chronic low back pain (CLBP) in Ireland’s primary care health system. Methods The six steps of the IM protocol were systematically applied to develop the self-management of osteoarthritis and low back pain through activity and skills (SOLAS) intervention through adaptation of the Facilitating Activity and Self-management in Arthritis (FASA) intervention. A needs assessment including literature reviews, interviews with patients and physiotherapists and resource evaluation was completed to identify the programme goals, determinants of SM behaviour, consolidated definition of SM and required adaptations to FASA to meet health service and patient needs and the evidence. The resultant SOLAS intervention behavioural outcomes, performance and change objectives were specified and practical application methods selected, followed by organised programme, adoption, implementation and evaluation plans underpinned by behaviour change theory. Results The SOLAS intervention consists of six weekly sessions of 90-min education and exercise designed to increase participants’ physical activity level and use of evidence-based SM strategies (i.e. pain self-management, pain coping, healthy eating for weight management and specific exercise) through targeting of individual determinants of SM behaviour (knowledge, skills, self-efficacy, fear, catastrophizing, motivation, behavioural regulation), delivered by a trained physiotherapist to groups of up to eight individuals using a needs supportive interpersonal style based on self-determination theory. Strategies to support SOLAS intervention adoption and implementation included a consensus building workshop with physiotherapy stakeholders, development of a physiotherapist training programme and a pilot trial with physiotherapist and patient feedback. Conclusions The SOLAS intervention is currently being evaluated in a cluster randomised controlled feasibility trial. IM is a time-intensive collaborative process, but the range of methods and resultant high level of transparency is invaluable and allows replication by future complex intervention and trial developers.

To investigate the psychometric properties of the Working Alliance Inventory Theory of Change Inventory (WATOCI) in physical rehabilitation.RASCH analysis was used to examine the validity, internal consistency, reliability and discriminative properties of the 16-item WATOCI. Data was obtained from a randomized controlled trial, which employed the WATOCI to measure the alliance between physical therapists and patients with chronic low back pain.The results indicated that 7 items on the 16-item WATOCI should need to be improved for use in physiotherapy settings. The resulting 9-item version of the WATOCI was found to be a uni-dimensional tool for measuring alliance, however, demonstrated a ceiling effect.There are several items in the WATOCI that require re-wording and/or re-contextualization prior to its use in clinical practice. Specifically, items relating more to the element social interaction did not discriminate well in this population and one solution may be to provide a therapy-specific context. Items regarding how well the patient understood the purpose of the treatment discriminated best between patients and this area is recommended for further development in the tool's assessment. It is recommended that future research address these issues prior to its use in clinical settings.

Objective To determine the effect of tai chi exercise on persistent low back pain. Methods We performed a randomized controlled trial in a general community setting in Sydney, New South Wales, Australia. Participants consisted of 160 volunteers between ages 18 and 70 years with persistent nonspecific low back pain. The tai chi group (n = 80) consisted of 18 40-minute sessions over a 10-week period delivered in a group format by a qualified instructor. The waitlist control group continued with their usual health care. Bothersomeness of back symptoms was the primary outcome. Secondary outcomes included pain intensity and pain-related disability. Data were collected at pre- and postintervention and analyzed by intent-to-treat. Results Tai chi exercise reduced bothersomeness of back symptoms by 1.7 points on a 0–10 scale, reduced pain intensity by 1.3 points on a 0–10 scale, and improved self-report disability by 2.6 points on the 0–24 Roland-Morris Disability Questionnaire scale. The followup rate was >90% for all outcomes. These results were considered a worthwhile treatment effect by researchers and participants. Conclusion This is the first pragmatic randomized controlled trial of tai chi exercise for people with low back pain. It showed that a 10-week tai chi program improved pain and disability outcomes and can be considered a safe and effective intervention for those experiencing long-term low back pain symptoms.

Background The working alliance, or collaborative bond, between client and psychotherapist has been found to be related to outcome in psychotherapy. Purpose The purpose of this study was to investigate whether the working alliance is related to outcome in physical rehabilitation settings. Data Sources A sensitive search of 6 databases identified a total of 1,600 titles. Study Selection Prospective studies of patients undergoing physical rehabilitation were selected for this systematic review. Data Extraction For each included study, descriptive data regarding participants, interventions, and measures of alliance and outcome—as well as correlation data for alliance and outcomes—were extracted. Data Synthesis Thirteen studies including patients with brain injury, musculoskeletal conditions, cardiac conditions, or multiple pathologies were retrieved. Various outcomes were measured, including pain, disability, quality of life, depression, adherence, and satisfaction with treatment. The alliance was most commonly measured with the Working Alliance Inventory, which was rated by both patient and therapist during the third or fourth treatment session. The results indicate that the alliance is positively associated with: (1) treatment adherence in patients with brain injury and patients with multiple pathologies seeking physical therapy, (2) depressive symptoms in patients with cardiac conditions and those with brain injury, (3) treatment satisfaction in patients with musculoskeletal conditions, and (4) physical function in geriatric patients and those with chronic low back pain. Limitations Among homogenous studies, there were insufficient reported data to allow pooling of results. Conclusions From this review, the alliance between therapist and patient appears to have a positive effect on treatment outcome in physical rehabilitation settings; however, more research is needed to determine the strength of this association.

Objectives To identify measures of adherence to nonpharmacologic self-management treatments for chronic musculoskeletal (MSK) populations; and to report on the measurement properties of identified measures. Data Sources Five databases were searched for all study types that included a chronic MSK population, unsupervised intervention, and measure of adherence. Study Selection Two independent researchers reviewed all titles for inclusion using the following criteria: adult (>18y) participants with a chronic MSK condition; intervention, including an unsupervised self-management component; and measure of adherence to the unsupervised self-management component. Data Extraction Descriptive data regarding populations, unsupervised components, and measures of unsupervised adherence (items, response options) were collected from each study by 1 researcher and checked by a second for accuracy. Data Synthesis No named or referenced adherence measurement tools were found, but a total of 47 self-invented measures were identified. No measure was used in more than a single study. Methods could be grouped into the following: home diaries (n=31), multi-item questionnaires (n=11), and single-item questionnaires (n=7). All measures varied in type of information requested and scoring method. The lack of established tools precluded quality assessment of the measurement properties using COnsensus-based Standards for the selection of health Measurement INstruments methodology. Conclusions Despite the importance of adherence to self-management interventions, measurement appears to be conducted on an ad hoc basis. It is clear that there is no consistency among adherence measurement tools and that the construct is ill-defined. This study alerts the research community to the gap in measuring adherence to self-care in a rigorous and reproducible manner. Therefore, we need to address this gap by using credible methods (eg, COnsensus-based Standards for the selection of health Measurement INstruments guidelines) to develop and evaluate an appropriate measure of adherence for self-management.

Background Physical activity and exercise therapy are among the accepted clinical rehabilitation guidelines and are recommended self-management strategies for chronic low back pain. However, many back pain sufferers do not adhere to their physiotherapist’s recommendations. Poor patient adherence may decrease the effectiveness of advice and home-based rehabilitation exercises. According to self-determination theory, support from health care practitioners can promote patients’ autonomous motivation and greater long-term behavioral persistence (e.g., adherence to physiotherapists’ recommendations). The aim of this trial is to assess the effect of an intervention designed to increase physiotherapists’ autonomy-supportive communication on low back pain patients’ adherence to physical activity and exercise therapy recommendations. Methods/Design This study will be a single-blinded cluster randomized controlled trial. Outpatient physiotherapy centers (N =12) in Dublin, Ireland (population = 1.25 million) will be randomly assigned using a computer-generated algorithm to either the experimental or control arm. Physiotherapists in the experimental arm (two hospitals and four primary care clinics) will attend eight hours of communication skills training. Training will include handouts, workbooks, video examples, role-play, and discussion designed to teach physiotherapists how to communicate in a manner that promotes autonomous patient motivation. Physiotherapists in the waitlist control arm (two hospitals and four primary care clinics) will not receive this training. Participants (N = 292) with chronic low back pain will complete assessments at baseline, as well as 1 week, 4 weeks, 12 weeks, and 24 weeks after their first physiotherapy appointment. Primary outcomes will include adherence to physiotherapy recommendations, as well as low back pain, function, and well-being. Participants will be blinded to treatment allocation, as they will not be told if their physiotherapist has received the communication skills training. Outcome assessors will also be blinded. We will use linear mixed modeling to test between arm differences both in the mean levels and the rates of change of the outcome variables. We will employ structural equation modeling to examine the process of change, including hypothesized mediation effects. Discussion This trial will be the first to test the effect of a self-determination theory-based communication skills training program for physiotherapists on their low back pain patients’ adherence to rehabilitation recommendations.

The primary objective of this study was to determine which questionnaire, the Roland Morris disability questionnaire (RMDQ) or the patient-specific functional scale (PSFS), was better at detecting change in activity limitation in a large cohort of patients with low back pain undergoing rehabilitation. A secondary aim was to determine if the responsiveness of the questionnaires was influenced by the patient’s level of activity limitation at baseline. Responsiveness statistics, including effect size statistics, Pearson’s r correlations and receiver operative characteristic (ROC) curve analysis were used to determine ability to detect change in activity limitation on 831 patients with low back pain. Data were analysed at two time points; directly after treatment (termed short-term) and several weeks post-treatment (termed mid-term). The data were subsequently re-analysed on sub-sets of the full cohort according to the level of activity limitation from RMDQ baseline scores. In the total cohort we found that the PSFS was more responsive than the RMDQ; however, in the subgroup with high activity limitation this pattern was not observed. This is true for time points up to 6 months post-treatment. In conclusion, the RMDQ and PSFS both demonstrate good responsiveness according to the definitions given in previous guidelines. The PSFS is more responsive than the RMDQ for patients with low levels of activity limitation but not for patients with high levels of activity limitation.

Objective To determine whether Tai Chi improves pain, disability, physical performance, and/or health-related quality of life (HRQOL) in people with chronic musculoskeletal pain. Methods Eight databases were searched for randomized controlled trials (RCTs). Two independent reviewers rated trial quality and extracted trial data. Effect sizes and 95% confidence intervals were calculated for individual trials, and pooled effect sizes were calculated using a random-effects model. Results Seven RCTs were selected for inclusion in the review. Of these, 6 studied people with chronic arthritis and 1 studied people with chronic tension headaches. The trials were typically small and of low methodologic quality. The pooled effect size for arthritic populations on a 0–100 scale was 10.1 (range 6.3–13.9) points for pain reduction, and was 9.6 (range 5.2–14.0) points for disability reduction. Additionally, physical performance and HRQOL outcomes favored the Tai Chi intervention, but of these outcomes, only the level of tension and satisfaction with general health were statistically significant. Conclusion The available data on the effect of Tai Chi are sparse and derived principally from low-quality studies. These data suggest that Tai Chi has a small positive effect on pain and disability in people with arthritis. The extent to which it benefits other forms of musculoskeletal pain is unclear.

The dark current of Quantum Well Inter-subband Photodetectors is affected by 1/f noise that limits the detectivity. This paper applies for the first time conventional quantum 1/f noise expressions to calculate the expected level of 1/f noise in QWIPs and applies the resulting engineering formulas to the case of GaInAs/InP and GaN/AlGaN QWIPs. Both the collisionless and collision-dominated cases are considered. The elementary process causing the dark current is the transfer of an electron from one well to the neighboring well. This happens under the influence of the applied electric field, and has in general both thermally activated and tunneling components. The larger the applied electric field, the larger is the squared velocity change of the carriers, and the larger is the obtained conventional quantum 1/f effect. The detectivity of the devices is calculated on this basis. Quantum well intersubband photodetectors (QWIPs) can be extended in principle from infrared into the THz region.

GaN-based FETs, HFETs and MODFETs are ideally suited for use in high-power amplifiers and oscillators, due to their large band gap and high operating voltages. According to the quantum 1/f theory, the larger effective mass implied for the carriers also leads to lower fundamental 1/f noise and to lower resulting phase noise close to the carrier frequency. We have therefore studied the quantum 1/f noise sources in the channel and in the gate insulation. For the channel, a combination of conventional and coherent Quantum 1/f Effect (Q1/fE) is present, with the conventional Q1/fE dominant in the sub-threshold part of the channel toward the drain. It turns out that the quantum 1/f parameter "s" that determines the fraction of the two forms of Q1/fE, is no longer increasing proportionally to the width of the device w, when the latter exceeds the length of the channel. A logarithmic dependence on w is obtained for s instead. This is why an extremely large width w does not automatically lead to coherent Q1/fE in HFETs. Conventional Q1/fE applies for the gate insulation, with contributions of the much larger piezoelectric Q1/fE in spontaneously polarized AlGaN, if gate leakage is present. The noise figure is calculated, including all contributions. Finally, the minimal expected oscillator phase noise is calculated from the Q1/fE in the dissipative elements, even for perfectly linear amplifiers, by multiplication with the inverse fourth power of the quality factor, as was first done by us for quartz in 1979.

Objectives To assess whether cognitive behavioural (CB) approaches improve disability, pain, quality of life and/or work disability for patients with low back pain (LBP) of any duration and of any age. Methods Nine databases were searched for randomised controlled trials (RCTs) from inception to November 2014. Two independent reviewers rated trial quality and extracted trial data. Standardised mean differences (SMD) and 95% confidence intervals were calculated for individual trials. Pooled effect sizes were calculated using a random-effects model for two contrasts: CB versus no treatment (including wait-list and usual care (WL/UC)), and CB versus other guideline-based active treatment (GAT). Results The review included 23 studies with a total of 3359 participants. Of these, the majority studied patients with persistent LBP (>6 weeks; n=20). At long term follow-up, the pooled SMD for the WL/UC comparison was -0.19 (-0.38, 0.01) for disability, and -0.23 (-0.43, -0.04) for pain, in favour of CB. For the GAT comparison, at long term the pooled SMD was -0.83 (-1.46, -0.19) for disability and -0.48 (-0.93, -0.04) for pain, in favour of CB. While trials varied considerably in methodological quality, and in intervention factors such as provider, mode of delivery, dose, duration, and pragmatism, there were several examples of lower intensity, low cost interventions that were effective. Conclusion CB interventions yield long-term improvements in pain, disability and quality of life in comparison to no treatment and other guideline-based active treatments for patients with LBP of any duration and of any age.

For imaging and remote sensing applications, the noise of the THz detector must be minimized. The quantum 1/f theory is introduced and used to obtain analytical expressions of noise in n + p diodes, Schottky diode THz detectors and mixers, a new type of suggested MEMS resonator based Thz detectors, QWIPs and bolometers. For the DAR and for THz communications we also consider phase noise in RTD and GaN/AlGaN HFET based THz generators.

Background Clinical practice guidelines for the treatment of low back pain suggest the inclusion of a biopsychosocial approach in which patient self-management is prioritized. While many physiotherapists recognise the importance of evidence-based practice, there is an evidence practice gap that may in part be due to the fact that promoting self-management necessitates change in clinical behaviours. Evidence suggests that a patient’s motivation and maintenance of self-management behaviours can be positively influenced by the clinician’s use of an autonomy supportive communication style. Therefore, the aim of this study was to develop and pilot-test the feasibility of a theoretically derived implementation intervention to support physiotherapists in using an evidence-based autonomy supportive communication style in practice for promoting patient self-management in clinical practice. Methods A systematic process was used to develop the intervention and pilot-test its feasibility in primary care physiotherapy. The development steps included focus groups to identify barriers and enablers for implementation, the theoretical domains framework to classify determinants of change, a behaviour change technique taxonomy to select appropriate intervention components, and forming a testable theoretical model. Face validity and acceptability of the intervention was pilot-tested with two physiotherapists and monitoring their communication with patients over a three-month timeframe. Results Using the process described above, eight barriers and enablers for implementation were identified. To address these barriers and enablers, a number of intervention components were selected ranging from behaviour change techniques such as, goal-setting, self-monitoring and feedback to appropriate modes of intervention delivery (i.e. continued education meetings and audit and feedback focused coaching). Initial pilot-testing revealed the acceptability of the intervention to recipients and highlighted key areas for refinement prior to scaling up for a definitive trial. Conclusion The development process utilised in this study ensured the intervention was theory-informed and evidence-based, with recipients signalling its relevance and benefit to their clinical practice. Future research should consider additional intervention strategies to address barriers of social support and those beyond the clinician level.

Background Tai chi is recommended for musculoskeletal conditions; however, the evidence for its clinical effectiveness is uncertain. Purpose The aim of this study was to determine whether tai chi is beneficial for clinical outcomes in people with musculoskeletal pain. Data Sources Seven databases were searched: Embase, PEDro, AMED, MEDLINE, CINAHL, SPORTDiscus, and the Cochrane Central Register of Controlled Trials. Study Selection Randomized controlled trials of tai chi for people with a chronic musculoskeletal condition were included. Data Extraction Two reviewers extracted data and rated risk of bias. Standardized mean differences (SMDs) and 95% confidence intervals (CI) were calculated for individual trials and pooled effect sizes were calculated using a random-effects model. Data Synthesis Fifteen studies were identified; these studies included people with osteoarthritis (80%), back pain (13%), and headache (7%). Using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach, moderate-quality evidence was found that tai chi was more effective than no treatment or usual care at short term on pain (SMD=−0.66 [95% CI=−0.85, −0.48]) and disability (SMD=−0.66 [95% CI=−0.85, −0.46]). The evidence for other outcomes was of low or very low quality and there was little information regarding long-term effects. Thus, although the number of publications in this area has increased, the rigor has not, hindering physical therapists' ability to provide reliable recommendations for clinical practice. Limitations The evidence provided in this review is limited by trials with small sample sizes, low methodological quality, and lack of long-term assessment. Conclusions In order for tai chi to be recommended as an effective intervention, more high-quality trials with large sample sizes assessing tai chi versus other evidence-based treatments at short term and at long term are needed.
