Evaluating outcome in osteoarthritis (OA) clinical research and practice requires reliable, valid and responsive patient-reported outcome measures (PROMs) and functional tests that reflect important problems experienced by people with OA. The goal of this work is to provide information to start to guide the reader in selecting measures for people with OA. In this narrative review, we begin by providing an overview of measurement properties that can help clinicians and researchers in making decisions about whether a measure might be appropriate for use in their research or clinical context. We then report evidence supporting the use of measures of pain (e.g., Pain Visual Analogue (VAS), Numeric Pain Rating Scale (NPRS), Intermittent and Constant Osteoarthritis Pain, PROMIS Pain Interference, and, for screening in research, the painDETECT and the Self-report Leeds Assessment of Neuropathic Symptoms and Signs) and fatigue (e.g., PROMIS-Fatigue) at a group level in clinical research. Several multi-dimensional joint-specific measures (e.g., Western Ontario McMaster Universities' Osteoarthritis Outcomes Scale, Knee/Hip Injury and Osteoarthritis Outcome Score, Oxford Hip/Knee Scale) also have evidence for group-level use. Functional tests (e.g., timed walk tests, 30 Second Chair Stand, Timed Up and Go, etc.) have measurement properties supporting their use at the group level in clinical research and at the individual patient level as do the pain VAS and NPRS. Other generic and disease-specific PROMs have been used in or could be used in OA studies but their measurement properties require further evaluation in people with OA.

Objective The objectives of this study were to: 1) identify predictors of subsequent surgery following initial treatment of proximal humerus fractures (PHF); and 2) generate valid risk prediction tools to predict subsequent surgery. Methods We identified PHF patients ≥ 50 years from 2004 to 2015 using health datasets in Ontario, Canada. We used procedural codes to classify patients into treatment groups of: 1) surgical fixation; 2) shoulder replacement; and 3) conservative. We used procedural and diagnosis codes to capture subsequent surgery within two years post fracture. We developed regression models for two thirds of each group to identify predictors of subsequent surgery, and the regression equations to develop risk tools to predict subsequent surgery. We used the final third of each cohort to evaluate the discriminative ability of the risk tools using c-statistics. Results We identified 20,897 PHF patients, 2,414 treated with fixation, 1,065 with replacement, and 17,418 treated conservatively. Predictors of reoperation following fixation included bone grafting, and nail or wire fixation vs. plate fixation, while poor bone quality was associated with reoperation following initial replacement. In conservatively treated patients, more comorbidities were associated with subsequent surgery, while age 70+, and discharge home following presentation lowered the odds of subsequent surgery. The risk tools were able to discriminate with c-statistics of 0.75-0.88 (derivation) and 0.51-0.79 (validation). Conclusion Our risk tools showed good to strong discriminative ability for patients treated with fixation and conservatively. These data may be used as the foundation to develop a clinically informative tool. Level of evidence Prognostic Level II.

Background The Episodic Disability Questionnaire (EDQ) is a generic 35-item patient-reported outcome measure of presence, severity and episodic nature of disability. We assessed the measurement properties of the Episodic Disability Questionnaire (EDQ) with adults living with HIV. Methods We conducted a measurement study with adults living with HIV in eight clinical settings in Canada, Ireland, United Kingdom, and United States. We electronically administered the EDQ followed by three reference measures (World Health Organization Disability Assessment Schedule; Patient Health Questionnaire; Social Support Scale) and a demographic questionnaire. We administered the EDQ only 1 week later. We assessed the internal consistency reliability (Cronbach’s alpha; >0.7 acceptable), and test-retest reliability (Intra Class Correlation Coefficient; >0.7 acceptable). We estimated required change in EDQ domain scores to be 95% certain that a change was not due to measurement error (Minimum Detectable Change (MDC95%)). We evaluated construct validity by assessing 36 primary hypotheses of relationships between EDQ scores and scores on the reference measures (> 75% hypotheses confirmed indicated validity). Results 359 participants completed the questionnaires at time point 1, of which 321 (89%) completed the EDQ approximately 1 week later. Cronbach’s alpha for internal consistency ranged from 0.84 (social domain) to 0.91 (day domain) for the EDQ severity scale, and 0.72 (uncertainty domain) to 0.88 (day domain) for the EDQ presence scale, and 0.87 (physical, cognitive, mental-emotional domains) to 0.89 (uncertainty domain) for the EDQ episodic scale. ICCs for test-retest reliability ranged from 0.79 (physical domain) to 0.88 (day domain) for the EDQ severity scale and from 0.71 (uncertainty domain) to 0.85 (day domain) for the EDQ presence scale. Highest precision was demonstrated in the severity scale for each domain (MDC95% range: 19–25 out of 100), followed by the presence (MDC95% range: 37–54) and episodic scales (MDC95% range:44–76). Twenty-nine of 36 (81%) construct validity hypotheses were confirmed. Conclusions The EDQ possesses internal consistency reliability, construct validity, and test-retest reliability, with limited precision when administered electronically with adults living with HIV across in clinical settings in four countries. Given the measurement properties, the EDQ can be used for group level comparisons for research and program evaluation in adults living with HIV.

OBJECTIVE To understand what sports orthopedic surgeons (OS), primary care physicians (PCPs) with sports medicine training, and physical therapists (PTs) managing nonelite athletes with anterior cruciate ligament (ACL) injury tell their patients about their osteoarthritis (OA) risk. METHODS An electronic survey was distributed by the Canadian Academy of Sport and Exercise Medicine (PCPs, OS), the Sports and Orthopedic Divisions of the Canadian Physiotherapy Association (PTs), and to OS identified through the Royal College of Physicians and Surgeons and the Canadian Orthopaedic Association. The survey included 4 sections: demographics, factors discussed, timing of discussions, and discussion of risk factors and their management. Proportions or means with 95% confidence intervals were calculated. RESULTS A total of 501 health care professionals (HCPs) responded (98 PCPs, 263 PTs, and 140 OS). Of those responding, 70-77% of physicians reported always discussing OA risk, but only 35% of PTs did. All HCPs reported that patient activities perceived as detrimental to knee health, ACL reinjury, and simultaneous injury to other structures in the knee were most often the reason for discussing OA risk. OA risk was discussed at initial management post-injury (65-94%), with few discussing risk subsequently. Eighty percent of physicians and 99% of PTs indicated that PTs were suited to provide OA risk and management information. CONCLUSION HCPs routinely managing people with ACL injury do not consistently discuss OA risk post-injury with them. Educational strategies for HCPs are urgently needed to develop care pathways inclusive of support for OA risk management following ACL injury.

ObjectivesThe Short-Form HIV Disability Questionnaire (SF-HDQ) was developed to measure the presence, severity and episodic nature of health challenges across six domains. Our aim was to assess the sensibility, utility and implementation of the SF-HDQ in clinical practice.DesignMixed methods study design involving semistructured interviews and questionnaire administration.ParticipantsWe recruited adults living with HIV and HIV clinicians in Canada, Ireland and the USA.MethodsWe electronically administered the SF-HDQ followed by a Sensibility Questionnaire (face and content validity, ease of usage, format) and conducted semistructured interviews to explore the utility and implementation of the SF-HDQ in clinical practice. The threshold for sensibility was a median score of >5/7 (adults living with HIV) and>4/7 (HIV clinicians) for ≥80% of items. Qualitative interview data were analysed using directed content analysis.ResultsMedian sensibility scores were >5 (adults living with HIV; n=29) and >4 (HIV clinicians; n=16) for 18/19 (95%) items. Interview data indicated that the SF-HDQ represents the health-related challenges of living with HIV and other concurrent health conditions; captures the daily episodic nature of HIV; and is easy to use. Clinical utility included measuring health challenges and change over time, guiding referral to specialists and services, setting goals, facilitating communication and fostering a multidisciplinary approach to care. Considerations for implementation included flexible, person-centred approaches to administration, and communicating scores based on personal preferences.ConclusionsThe SF-HDQ possesses sensibility and utility for use in clinical settings with adults living with HIV and HIV clinicians in three countries.

Summary Objective To report outcomes across three countries for patients with symptomatic knee or hip OA attending the evidence-based education and exercise therapy program Good Life with osteoArthritis from Denmark (GLA:D®). Design GLA:D® is a structured treatment program including 2–3 patient education sessions and 12 supervised exercise sessions delivered over 8 weeks by certified health care practitioners. The program was introduced in Denmark in 2013, in Canada 2015 and in Australia 2016. Absolute mean change in pain intensity, number of chair stands in 30 s, 40 m walk test time and Knee injury and Osteoarthritis Outcome Score (KOOS)/Hip dysfunction and Osteoarthritis Outcome Score (HOOS) QOL subscale scores from baseline to immediately after treatment were reported as means and 95 % CIs and proportion of responders for each country. Results Patients from the three countries improved 26–33% in mean pain intensity, 8–12% in walking speed, 18–30% in chair stand ability and 12–26% in joint-related quality of life from baseline to immediately after treatment, with no clinically relevant differences between patients with hip and knee OA. These improvements correspond with moderate to large within-group effect sizes and 43–47 % of the patients experienced clinically relevant pain reductions. Conclusion About half or more of patients across the three countries were categorized as responders for pain and objective function following the implementation of GLA:D®. These findings indicate positive patient outcomes associated with GLA:D® participation across varying health care systems from implementation of guideline-based patient education and exercise therapy for knee and hip OA.

This study compared the effectiveness of soft vs hard orthotics in treating heel pain and plantar fasciitis in adults. It also compared the level of function after orthotic use, cost, and number of visits for orthotics and explored whether age was a factor in orthotic effectiveness.Randomized controlled trial. Before randomization, patients were stratified by age (younger vs older adults) in blocks of 4 to ensure that there were an equal number of participants in each group (soft vs hard orthotics).An orthotic clinic in a community-based hospital and a private orthotic clinic.The participants were adults aged 18 years or older (N=44) with heel pain and plantar fasciitis.Participants received hard or soft customized orthotics.Participants rated their pain intensity and pain interference before and after orthotic use using subscales from the Brief Pain Inventory. Function was similarly measured using the Late Life Function and Disability Instrument: Function component. Analyses of age, cost, and number of visits were also compared.There was a reduction in pain intensity (P=.010) and pain interference (P.001) but no change in function over time (P=.333), and no difference between the groups who received hard vs soft orthotics. Age had no effect on orthotic effectiveness. Soft orthotics were less expensive (P.0001) and required fewer visits for fabrication (P.0001).Both soft and hard orthotics provided effective pain relief, but soft orthotics are less expensive.

Background Disability is an increasingly important health-related outcome to consider as more individuals are now aging with Human Immunodeficiency Virus (HIV) and multimorbidity. The HIV Disability Questionnaire (HDQ) is a patient-reported outcome measure (PROM), developed to measure the presence, severity and episodic nature of disability among adults living with HIV. The 69-item HDQ includes six domains: physical, cognitive, mental-emotional symptoms and impairments, uncertainty and worrying about the future, difficulties with day-to-day activities, and challenges to social inclusion. Our aim was to develop a short-form version of the HIV Disability Questionnaire (SF-HDQ) to facilitate use in clinical and community-based practice among adults living with HIV. Methods We used Rasch analysis to inform item reduction using an existing dataset of adults living with HIV in Canada (n = 941) and Ireland (n = 96) who completed the HDQ (n = 1037). We evaluated overall model fit with Cronbach’s alpha and Person Separation Indices (PSIs) (≥ 0.70 acceptable). Individual items were evaluated for item threshold ordering, fit residuals, differential item functioning (DIF) and unidimensionality. For item threshold ordering, we examined item characteristic curves and threshold maps merging response options of items with disordered thresholds to obtain order. Items with fit residuals > 2.5 or less than − 2.5 and statistically significant after Bonferroni-adjustment were considered for removal. For DIF, we considered removing items with response patterns that varied according to country, age group (≥ 50 years versus Results We removed 34 items, resulting in a 35-item SF-HDQ with domain structure: physical (10 items); cognitive (3 items); mental-emotional (5 items); uncertainty (5 items); difficulties with day-to-day activities (5 items) and challenges to social inclusion (7 items). Overall models’ fit: Cronbach’s alphas ranged from 0.78 (cognitive) to 0.85 (physical and mental-emotional) and PSIs from 0.69 (day-to-day activities) to 0.79 (physical and mental-emotional). Three items were rescored to achieve ordered thresholds. All domains demonstrated unidimensionality. Three items with DIF were retained because of their clinical importance. Conclusion The 35-item SF-HDQ offers a brief, comprehensive disability PROM for use in clinical and community-based practice with adults living with HIV.

Understand factors associated with pain intensity responder status following non-surgical hip OA intervention, according to sex.Data were from individuals with hip OA participating in the Danish GLA:D® 8-week education and exercise program. Factors captured at program entry: age, education, mental well-being, comorbidities, body mass index, symptoms in hip, knee and low back, and program-specific factors: education sessions, former participant lecture, supervised exercise sessions. Pain intensity was captured at baseline and 3-months (post-program) on a 0-100 visual analogue scale. Response was defined as pain intensity improvement ≥30% from baseline to post-program. Logistic regression was used and conducted separately in males and females.The sample included 791 males and 2,253 females. Females had a mean baseline pain of 47.2/100 (95% CL: 46.4, 48.1) and males 41.7 (95% CL: 40.3, 43.1). By post-program, the proportion of pain responders was 50.4% among females and 45.8% among males (difference p=0.025). Among females, program-specific factors (attending former participant lecture and more supervised exercise sessions) were positively associated with pain response, as were better mental well-being and fewer comorbidities, while symptoms in other joints/site were associated with a decreased likelihood of response. Among males, program-specific factors were not associated with response, while better mental well-being and fewer comorbidities were associated with being a responder.Findings suggest that the influence of some factors on pain response differ for males and females, and point to a potential need for targeted approaches for males and females who may require different key messages/approaches from healthcare providers.

Background:In patients undergoing cartilage restoration of the knee, limited information is available regarding clinically important difference (CID) and Patient Acceptable Symptomatic State (PASS) estimates for commonly used patient-reported outcome measures (PROMs).Purpose:The objective of this study was to determine the CID and PASS in the population with knee cartilage restoration for the Knee injury and Osteoarthritis Outcome Score (KOOS), the International Knee Documentation Committee Subjective Knee Form (IKDC) score, and the Lysholm score.Study Design:Cohort study (Diagnosis); Level of evidence, 2.Methods:Between 2012 and 2017, patients who underwent a cartilage restoration procedure were prospectively enrolled. Patients completed the KOOS, IKDC, and Lysholm, all of which were scored from 0 to 100, and completed relevant anchor questions at baseline and 1 year postoperatively. Receiver operating characteristic curve analyses were conducted to determine CID and PASS cutoff points. Multivariable regression analyses were performed to determine the effect of age, sex, and baseline score on likelihood of achieving CID and PASS.Results:Of the 113 patients enrolled, 53 (47%) were male, and the mean age was 36 years. The CID values for the PROMs were 10.7 for KOOS Symptoms, 8.3 for KOOS Pain, 8.8 for KOOS Activities of Daily Living (ADL), 30.0 for KOOS Sports and Recreation, 18.8 for KOOS Quality of Life (QOL), 9.2 for IKDC, and 13.0 for Lysholm. The PASS values were 71.5 for KOOS Symptoms, 72.2 for KOOS Pain, 86.8 for KOOS ADL, 43.8 for KOOS Sports and Recreation, 50.0 for KOOS QOL, 62.1 for IKDC, and 70.0 for Lysholm. Patients with higher baseline scores were more likely to achieve PASS for the IKDC (odds ratio, 2.28; P = .03). Baseline score did not have an effect on the likelihood of achieving CID. Younger age was an independent predictor of achieving PASS and CID across all outcomes ( P < .05), but sex did not have such an effect.Conclusion:This study determined CID and PASS values for the KOOS, IKDC, and Lysholm scores among patients treated with knee cartilage restoration. Younger age was a positive prognostic variable, and higher baseline scores implied achieving PASS for the IKDC. The information in this study can be used in designing randomized controlled trials, counseling individual patients as to anticipated outcomes, and conducting responder analyses when evaluating new cartilage technology from a regulatory perspective.

The aim of this narrative review was to summarize the beneficial effects of exercise for those with symptomatic hip and knee osteoarthritis (OA) utilizing data along the pipeline from translational to clinical studies to implementation into clinical practice. Exercise is first line treatment for managing symptomatic hip and knee OA. Aerobic, strengthening and neuromuscular approaches are all effective in reducing pain and improving function. Exercise dose and supervision may be more important. Twelve or more supervised exercise sessions seem superior to fewer sessions. Education about the condition, the role of exercise in reducing pain and improving function, and strategies for increasing physical activity is also key as long-term adherence to ongoing home exercise after program attendance is needed to maintain effects. The proposed mechanisms by which exercise improves pain and function in people with OA include general systemic effects and those local to the joint. General mechanisms include neural and systemic inflammation effects. Local mechanisms include exercise effects on muscle and other joint-related structures as well as local joint inflammation. Exercise effects on pain are as large or larger than for medications such as paracetamol and NSAIDs. Similar magnitude in pain relief and improvement in function from clinical trials has been shown immediately after the program and at 1-year follow-up in evidence-based structured education and exercise programs implemented into clinical practice in several countries. These programs are cost-effective. Although clinicians around the world are slowly adopting exercise as OA treatment, system changes are required to facilitate implementation of evidence-based exercise programs into clinical practice. Enhanced availability of education and supervised exercise programs and reimbursement schemes with support from publicly funded health services that reduce access barriers for patients are needed to support more universal evidence-based management and reduce the burden of symptomatic OA.

BACKGROUND AND OBJECTIVES Limb salvage surgery remains the standard treatment in bone and soft tissue tumors. Toronto Extremity Salvage Score (TESS) is the most used quality of life measure. Our objective was to perform cross-cultural adaptation and validation in Italian, testing test-retest reliability, construct validity, and responsiveness. METHODS We interviewed patients already treated for content validity. A total of 124 patients completed TESS and other questionnaires presurgery, at 3 months, 3 months + 2 weeks, and 6 months follow-up. We calculated intraclass correlation coefficients (ICCs) for reliability, associations with Pearson's r, and change over time with paired T tests. RESULTS A new item regarding touch-screen devices was added to the upper extremity (UE) questionnaire. ICC resulted of 0.99 for lower extremity (LE) and 0.98 for UE patients, Pearson's r between TESS and Musculoskeletal Tumor Society was .66 and .64, EuroQol-5D-5L r was .62 and .61, and r between TESS and short form-36 physical function subscale was .76 and .71 for LE and UE groups, respectively. Paired T test results were statistically significant to detect change over time (0.03, 0.04, and 0.04 for LE groups and 0.03, 0.01, and 0.04 for UE groups). CONCLUSION The Italian version of TESS can be used for the bone and soft tissue sarcoma population in clinical trials in Italy and with Italian speaking patients abroad to ensure patients' perspectives for efficacy and efficiency of treatments.

Objectives Breast cancer (BrC) and its treatments impair health-related quality of life (HRQoL). Utility is a measure of HRQoL that includes preferences for health outcomes, used in treatment decision-making. Generic preference-based instruments lack BrC-specific concerns, indicating the need for a BrC-specific preference-based instrument. Our objective was to determine dimensions of the European Organisation for Research and Treatment of Cancer (EORTC) general cancer (QLQ-C30) and breast module (BR45) instruments, the first step in our development of the novel Breast Utility Instrument (BUI). Methods Patients (n = 408) attending outpatient BrC clinics at an urban cancer centre, and representing a spectrum of BrC health states, completed the QLQ-C30 and BR45. We performed confirmatory factor analysis of the combined QLQ-C30 and BR45 using mean-and variance-adjusted unweighted least squares estimation. The hypothesized factor model was based on clinical relevance, item distributions, missing data, item-importance, and internal reliability of dimensions. Models were evaluated based on global and item fit, local areas of strain, and likelihood ratio tests of nested models. Results Our final model had 10 dimensions: physical and role functioning, emotional functioning, social functioning, body image, pain, fatigue, systemic therapy side effects, sexual functioning and enjoyment, arm and breast symptoms, and endocrine therapy symptoms. Good overall model fit was achieved: χ2/df: 1.45, Tucker-Lewis index: 0.946, comparative fit index: 0.951, standardized root-mean-square residual: 0.069, root-mean-square error of approximation: 0.033 (0.030–0.037). All items had salient factor loadings (λ>0.4, p Conclusions We identified important BrC HRQoL dimensions to develop the BUI, a BrC-specific preference-based instrument.

Fitness coaches need to understand the needs of people living with HIV engaged in community-based exercise (CBE) to be competent in developing exercises programs with this population. Our aim was to understand coaches’ experiences engaging in a CBE intervention with PLWH in an urban center in Canada. As part of a broader study, coaches supervised weekly hour-long individualized exercise sessions with PLWH over a six-month period. Using qualitative longitudinal methods, we interviewed coaches up to three times over six months. Transcribed interviews were analyzed cross-sectionally and longitudinally. Seven coaches participated in 15 interviews. Developing confidence, improving health and experiencing a sense of community were viewed as key benefits to PLWH by the coaches. Challenges included accommodating the episodic nature of HIV and ensuring they felt prepared to work with PLWH. Understanding the experiences of coaches engaged in CBE can assist in tailoring exercise programs to meet the needs of PLWH.

Purpose Our aim was to examine the impact of a community-based exercise (CBE) intervention on cardiorespiratory fitness, cardiovascular health, strength, flexibility, and physical activity outcomes among adults living with HIV. Methods We conducted a longitudinal intervention study with community-dwelling adults living with HIV in Toronto, Canada. We measured cardiopulmonary fitness (V̇O2peak (primary outcome), heart rate, blood pressure), strength (grip strength, vertical jump, back extension, push-ups, curl ups), flexibility (sit and reach test), and self-reported physical activity bimonthly across three phases. Phase 1 included baseline monitoring (8 months); Phase 2 included the CBE Intervention (6 months): participants were asked to exercise (aerobic, strength, balance and flexibility training) for 90 minutes, 3 times/week, with weekly supervised coaching at a community-based fitness centre; and Phase 3 included follow-up (8 months) where participants were expected to continue with thrice weekly exercise independently. We used segmented regression (adjusted for baseline age and sex) to assess the change in trend (slope) among phases. Our main estimates of effect were the estimated change in slope, relative to baseline values, over the 6 month CBE intervention. Results Of the 108 participants who initiated Phase 1, 80 (74%) started and 67/80 (84%) completed the intervention and 52/67 (77%) completed the study. Most participants were males (87%), with median age of 51 years (interquartile range (IQR): 45, 59). Participants reported a median of 4 concurrent health conditions in addition to HIV (IQR: 2,7). Participants attended a median of 18/25 (72%) weekly supervised sessions. Change in V̇O2peak attributed to the six-month Phase 2 CBE intervention was 0.56 ml/kg/min (95% Confidence Interval (CI): -1.27, 2.39). Significant effects of the intervention were observed for systolic blood pressure (-5.18 mmHg; 95% CI: -9.66, -0.71), push-ups (2.30 additional push-ups; 95% CI: 0.69, 3.91), curl ups (2.89 additional curl ups; 95% CI: 0.61, 5.17), and sit and reach test (1.74 cm; 95% CI: 0.21, 3.28). More participants engaged in self-reported strength (p Conclusion Adults living with HIV who engaged in this six-month CBE intervention demonstrated inconclusive results in relation to V̇O2peak, and potential improvements in other outcomes of cardiovascular health, strength, flexibility and self-reported physical activity. Future research should consider features tailored to promote uptake and sustained engagement in independent exercise among adults living with HIV.

Supplemental Digital Content is Available in the Text. Perineural local anesthetic and steroid injections do not confer an analgesic benefit for trauma- or compression-related peripheral neuropathic pain. A higher degree of catastrophizing reduces the analgesic benefit with treatments for neuropathic pain., Introduction: Trauma and compression are common causes of peripheral neuropathic pain (NP) refractory to conventional medical management (CMM). The role of perineural interventions in relieving this type of pain is unclear. Objectives: The objectives of this retrospective study were to determine the analgesic benefits of adding a combination of perineural local anesthetic and steroids (LA-S) to CMM compared with CMM alone in patients who had moderate-to-severe refractory NP after trauma to the ankle and the foot. Methods: Health care records of 60 patients in exposed (3 injections of perineural LA-S at weekly intervals with CMM) and 60 in unexposed (CMM) cohorts were reviewed. Data on patient characteristics, pain, and mental and physical function were extracted at baseline and at the postintervention follow-up. Data were analyzed to evaluate analgesic benefit from the study interventions and the impact of baseline characteristics. Results: Perineural LA-S with CMM cohort had lower pain numerical rating scale scores at 1 to 3 months after the intervention as compared to the CMM alone cohort (5.50 [interquartile range 4.00–7.00] and 7.00 [interquartile range 5.00–8.00], respectively; P < 0.01). However, multivariable analysis did not show an independent beneficial analgesic effect with the addition of perineural LA-S to CMM compared with CMM alone. A greater severity of preintervention catastrophizing (each unit increase in pain catastrophizing score increased pain score at follow-up by 0.04, 95% confidence interval: 0.01–0.07) was associated with reduction in the analgesic benefit. Conclusion: Perineural local anesthetic and steroid injections do not confer an analgesic benefit for trauma- or compression-related peripheral NP.

Objectives: This study aims to identify factors that influence older adults’ reintegration to normal living 2 years following a hip fracture and the association between caregiver burden and reintegration over time. Methods: This longitudinal cohort study followed 76 community-dwelling older adults and their caregivers for 2 years post-hip fracture. The primary outcome was Reintegration to Normal Living Index (RNLI), and the secondary outcome was caregiver burden. Results: Older adults scored significantly lower on RNLI at 18 to 24 months if they had few social interactions, cognitive impairment, or lower pre-fracture functional status. During follow-up, greater independence in activities of daily living and greater mobility were each positively associated with RNLI. Caregiver burden reduced if reintegration improved. Implications: Results suggest a need for targeted interventions for older adults’ post-hip fracture to improve their function to enhance their reintegration to normal living and to support caregivers in decreasing their burden of care.

Summary Objective To systematically review the minimal clinically important difference (MCID) and patient acceptable symptom state (PASS) estimates in pain and function measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) in patients who underwent primary total knee replacement (TKR) and primary total hip replacement (THR). Design The study was carried out following PRISMA recommendations. We searched five electronic databases. Two reviewers independently screened titles, abstracts and full-text papers using a priori inclusion/exclusion criteria. Data were extracted by two independent reviewers. Data were synthesized, with WOMAC values converted to 0–100 scores (0 = best, 100 = worst). Results Thirteen studies were included. Research methods used to calculate MCIDs and PASS varied across studies (e.g., using anchor-based or distribution methods, wording of anchor questions within anchor-based methods). Baseline WOMAC scores also varied across studies. Across studies and methods, MCIDs for the WOMAC in patients undergoing TKR ranged from 13.3 to 36.0 for pain and 1.8–33.0 for function; values for WOMAC in THR ranged from 8.3 to 41.0 for pain and from 9.7 to 34.0 for function. PASS cut-offs for TKR ranged from 25.0 to 28.6 for pain and 32.3–36.7 for function, and cut-offs for THR from 15.0 to 30.6 for pain and 28.0–42.0 for function. Conclusion Although the WOMAC is a commonly used measure for a single condition, the variability in methods used to calculate MCID and PASS estimates results in a range of values across studies making it unclear whether values reported in the literature can be applied with confidence. Future research is needed to refine methods used to calculate MCIDs and PASS.

Medical research increasingly makes use of embodiment concepts to understand how illness disrupts unity of body and self. However, few have applied embodiment concepts in total joint replacement (TJR), an effective treatment for end‐stage arthritis. In considering why a troubling proportion of TJR recipients have continued pain and functional limitation, we ask: what role might be played by the embodied experience of living with an implant? Relevant theoretical models and prior research on embodiment in musculoskeletal health and transplantation are reviewed. Our findings suggest a research agenda with implications for addressing suboptimal outcomes in TJR.

Objective: To compare and contrast the perspectives of patients with arthritis and those of rehabilitation professionals regarding starting and sustaining use of physical activity trackers (PATs). Methods: We conducted focus group sessions with patients, physiotherapists, and occupational therapists in Ontario, Alberta, or British Columbia, Canada. To be eligible, patients must have self-reported a diagnosis of inflammatory or osteoarthritis. Rehabilitation professionals reported that at least 40% of their caseload was dedicated to arthritis care. Participants had any level of experience with PATs. A thematic analytic approach was used. Results: The following 3 themes were identified: 1) anticipating sharing objective measures of physical activity. Participants agreed that use of PATs had the potential to improve consultations between patients with arthritis and rehabilitation professionals but were uncertain how to achieve this potential; 2) perceived or experienced barriers to start or continue using a PAT. Participants shared doubts about whether existing PATs would meet specific needs of patients with arthritis and expressed concerns about possible negative impacts; and 3) bolstering motivation? Although there was agreement that use of PATs could bolster the motivation of patients who were already active, patients and rehabilitation professionals had different opinions regarding whether use of PATs alone would motivate patients to start increasing activity levels. Conclusion: Our study highlights similarities and differences between the perspectives of patients and rehabilitation professionals regarding the potential value and risks of integrating PATs into arthritis self-management. Despite agreement about the potential of PATs, participants were uncertain how to effectively incorporate these tools to enhance patient–clinician consultations and had differing views about whether use of PATs would support a patient's motivation to be active. © 2018, American College of Rheumatology

Summary Introduction Anterior cruciate ligament (ACL) injury is a risk factor for developing knee osteoarthritis (OA). We developed an intervention to support people manage risk factors for OA. Methods We conducted one-on-one interviews with 20 individuals with OA symptoms 6–15 years post ACL injury and used a nominal group process during a workshop with 40 patients and healthcare professionals (HCPs) to elicit information on the intervention content and delivery characteristics (timing, HCPs, and methods). Interview data were analyzed using content analysis. Nominal group ideas with importance ratings ≥5 of 7 met criteria for inclusion. Results were integrated, considering similarities and differences. Results Eight content categories were identified: 1. understanding knee injury and expectations about recovery; 2. understanding OA risk; 3. understanding OA signs and symptoms; 4. managing OA risk; 5. managing knee OA symptoms; 6. information for influencers; 7. credible sources; and, 8. updates on new evidence and treatments. Delivery timing reflected a lifespan approach from time of injury through symptomatic knee OA management. Although multiple media for delivery were identified, introductory face-to-face discussions and opportunity for re-accessing HCPs were critical. All HCPs who treat people with ACL should be familiar with and able to deliver the intervention. Conclusions This co-development approach identified that an intervention to support people with ACL injury to limit and manage knee OA requires content embedded within an easily accessible, multi-media delivery model with capacity for check-back with HCPs that is appealing to different age groups and personal preferences over the lifespan post injury.

Background: Disability is an increasingly important health-related outcome to consider as more individuals are now aging with HIV and multimorbidity. The HIV Disability Questionnaire (HDQ) is a patient-reported outcome measure (PROM), developed to measure the presence, severity and episodic nature of disability among adults living with HIV. The 69-item HDQ includes six domains: physical, cognitive, mental-emotional symptoms and impairments, uncertainty and worrying about the future, difficulties with day-to-day activities, and challenges to social inclusion. Our aim was to develop a Short-Form version of the HIV Disability Questionnaire (SF-HDQ) to facilitate use in clinical and community-based practice among adults living with HIV.Methods: We used Rasch analysis to inform item reduction using an existing dataset of adults living with HIV in Canada (n=941) and Ireland (n=96) who completed the HDQ (n=1037). We evaluated overall model fit with Cronbach’s alpha and Person Separation Indices (PSIs) (≥ 0.70 acceptable). Individual items were evaluated for item threshold ordering, fit residuals, differential item functioning (DIF) and unidimensionality. For item threshold ordering, we examined item characteristic curves and threshold maps merging response options of items with disordered thresholds to obtain order. Items with fit residuals >2.5 or less than -2.5 and statistically significant after Bonferroni-adjustment were considered for removal. For DIF, we considered removing items with response patterns that varied according to country, age group (≥50 years versus Results: We removed 34 items, resulting in a 35-item SF-HDQ with domain structure: physical (10 items); cognitive (3 items); mental-emotional (5 items); uncertainty (5 items); difficulties with day-to-day activities (5 items) and challenges to social inclusion (7 items). Overall models’ fit: Cronbach’s alphas ranged from 0.78 (cognitive) to 0.85 (physical and mental-emotional) and PSIs from 0.69 (day-to-day activities) to 0.79 (physical and mental-emotional). Three items were rescored to achieve ordered thresholds. All domains demonstrated unidimensionality. Three items with DIF were retained because of their clinical importance.Conclusion: The 35-item SF-HDQ offers a brief, comprehensive disability PROM for use in clinical and community-based practice with adults living with HIV.

Aim To develop a patient-reported outcome measure that comprehensively captures the health-related priorities of children with Duchenne muscular dystrophy (DMD). Method Children with DMD and their parents completed the iteratively revised versions of the Caregiver Priorities and Child Health Index of Life with Disabilities (CPCHILD), followed by a cognitive interview to develop a pilot version of a new measure. Multidisciplinary health care professionals completed an item-by-item analysis of the measure and a 14-item sensibility questionnaire. Minimum content validity ratio for each item of the new measure and the mean score (0-7) for the items of the sensibility questionnaire were calculated. Results The CPCHILD underwent changes over 19 interviews with children and their parents, resulting in the pilot Muscular Dystrophy Child Health Index of Life with Disabilities (MDCHILD). The content validity ratio of each MDCHILD item ranged from 0.85 to 1 based on health care professionals' ratings. The mean score exceeded the threshold of four for all items of the sensibility questionnaire. Based on child, parent, and health care professional recommendations, 16 items were added, six eliminated, and 15 items modified from the original CPCHILD. The MDCHILD consists of 47 items over seven domains. Interpretation The MDCHILD met all sensibility criteria by children with DMD, their parents, and health care professionals, and is ready for psychometric evaluation. What this paper adds The Muscular Dystrophy Child Health Index of Life with Disabilities (MDCHILD) is a new patient-reported outcome measure for Duchenne muscular dystrophy (DMD). The Priority Framework of Outcomes underpins the content for the MDCHILD. The MDCHILD incorporates the health-related priorities of males with DMD and their parents. The MDCHILD was deemed sensible by children, their parents, and health care professionals.

Limitation of functional ability is a major feature of Huntington's disease (HD). The International Parkinson and Movement Disorder Society (MDS) commissioned the appraisal of the use and clinimetric properties of clinical measures of functional ability that have been applied in HD studies and trials to date, to make recommendations regarding their use based on standardized criteria. After a systematic literature search, we included a total of 29 clinical measures grouped into two categories: (1) performance-based measures (e.g., balance, walking, and reaching/grasping), and (2) rating scales. Three performance-based measures are rated as "recommended": the Tinetti Mobility Test for screening of fall risk and for severity assessment of mobility in patients with manifest HD (up to stage III); the Berg Balance Scale for severity of balance impairment; and the Six-Minute Walk Test for assessment of walking endurance (severity) in HD subjects with preserved ambulation. No rating scale targeting functional ability reached a "recommended" status either for screening or severity measurement. The main challenges identified in this review include applying widely accepted conceptual frameworks to the identified measures, the lack of validation of clinical measures to detect change over time, and absence of validated measures for upper limb function. Furthermore, measures of capacity or ability to perform activities of daily living had ceiling effects in people with early and pre-manifest HD. We recommend that the MDS prioritize the development of new scales that capture small, but meaningful changes in function over time for outcome assessment in clinical trials, particularly in earlier stages of HD.

The compromise of quality of life in Huntington's disease is a major issue, both for individuals with the disease as well as for their caregivers. The International Parkinson and Movement Disorder Society commissioned a review of the use and clinimetric validation status of measures used in Huntington's disease to assess aspects related with quality of life and to make recommendations on their use following standardized criteria. We included both patient‐centered measures (patient health‐related quality‐of‐life measures) and caregiver‐centered measures (caregiver quality‐of‐life measures). After conducting a systematic literature search, we included 12 measures of patient health‐related quality of life and 2 measures of caregiver quality of life. Regarding patient‐centered measures, the Medical Outcomes Study 36‐Item Short‐Form Health Survey is “recommended” as a generic assessment of health‐related quality of life in patients with Huntington's disease. The 12‐Item Short Form Health Survey, the Sickness Impact Profile, the 12‐item World Health Organization Disability Assessment Schedule, and the Huntington's Disease Health‐Related Quality of Life questionnaire are “suggested.” No caregiver‐centered quality‐of‐life measure obtained a “recommended” status. The Alzheimer's Carer's Quality of Life Inventory and the Huntington's Disease Quality of Life Battery for Carers are “suggested.” Recognizing that the assessment of patient health‐related quality of life can be challenging in Huntington's disease, as patients may lack insight and there is insufficient clinimetric testing of these scales, the committee concluded that further validation of currently available health‐related quality‐of‐life measures should be undertaken, namely, those Huntington's disease–specific health‐related quality‐of‐life measures that have recently been reported and used.

In contrast with other major chronic conditions such as heart disease and stroke, cancer care does not routinely integrate evidence-based rehabilitation services within the standard continuum. The objectives of the present project were to develop a rehabilitation planning consultation (rpc) for survivors of head-and-neck (hn) cancer, to test its feasibility, and to make refinements. Using intervention mapping, the rpc-alpha was developed by examining potential theoretical methods and practical applications relative to the program objectives. During feasibility testing, a single case series was conducted with survivors of hn cancer who had completed their cancer treatment within the preceding 11 months, iterative refinements were made after each case. The rpc-alpha was led by a rehabilitation professional and was based on self-management principles. The initial consultation included instruction in a global cognitive strategy, goal-setting, introduction to available resources, action planning, and coping planning. A follow-up consultation was conducted a few weeks later. Of 9 participants recruited, 5 completed post-intervention assessments. Participants reported that the rpc helped them to make rehabilitation plans. The rpc was feasible to use and satisfactory to a small group of hn cancer survivors. A pilot test of the refined version is in process.

Total knee replacement (TKR) is an increasingly common surgery among individuals with osteoarthritis (OA). Although the outcomes of this surgery are generally deemed positive, many are not fully satisfied with their return to pre-TKR occupations. The literature on pre-TKR occupational engagement is limited and primarily describes how the symptoms associated with OA restrict participation in occupation with little attention given to the significance occupations hold for individuals waiting for a TKR. A secondary analysis of eight purposively extracted transcripts from a primary study examining why people with OA do or do not re-engage in pre-operative occupations following hip or knee replacement was conducted. A qualitative thematic analysis approach was used to examine the pre-TKR experiences of these individuals from an occupational perspective. Three themes were identified: (1) living with OA: it is more than just the knee, (2) gradually losing my occupational identity, and (3) losing too much—...

To determine (a) clinical classes of injured workers with chronic low back pain (CLBP), (b) predictors of class membership and (c) associations of classes with baseline work status. Patients with CLBP from a tertiary care outpatient clinic in Toronto, Canada were sampled. Latent class analysis was applied to determine class structure using physical, psychological and coping indicators. Classes were interpreted by class-specific means and analyzed for predictors of membership. Lastly, association of the classes with being off work was modeled. A 3-class model was chosen based on fit criteria, theoretical and clinical knowledge of this population. The resultant 3 classes represented low, moderate and high levels of clinical severity. Predictors of being in the high severity group compared to the low severity group were

The Toronto Extremity Salvage Score (TESS) is a widely used disease-specific patient-completed questionnaire for the assessment of physical function in patients with musculoskeletal tumors; however, there had not been the validated Japanese version of the TESS. The aim of this study was to validate the Japanese version of the TESS in patients with musculoskeletal tumors in the upper extremity.After developing a Japanese version of the TESS, the questionnaire was administered to 53 patients to examine its reliability and validity in comparison with the Musculoskeletal Tumor Society (MSTS) scoring system and Short Form-36 (SF-36).Test-retest reliability with intraclass correlation coefficient (0.93) and internal consistency with Cronbach's alpha (0.90) were excellent. Factor analysis showed that the construct structure consisted of 3-item clusters, and the Akaike Information Criterion network also demonstrated that the items could be divided into 3 domains according to their content. The TESS strongly correlated with the MSTS rating scale (r = 0.750; P 0.001) and the SF-36 physical functioning scale (r = 0.684; P 0.001). However, as expected, the TESS had low correlations with the SF-36 mental health and role-emotional subscales and the MSTS scoring system manual dexterity domain.Our study suggests that the TESS is a reliable and valid instrument to measure patient-reported physical functioning in patients with upper extremity sarcoma.

Summary Objective Symptoms resembling neuropathic pain (neuropathic-like symptoms) are prevalent in osteoarthritis (OA) populations. Scales that measure neuropathic-like symptoms frequently were established in groups with true neuropathic pain conditions and have not been assessed in OA. We assessed the psychometric properties of the Neuropathic Pain Scale (NPS) in subjects with OA undergoing total knee replacement (TKR). Design In a prospective study of adults undergoing TKR for OA, we assessed baseline distributions, acceptability (completion rate), internal consistency (Cronbach's alpha), responsiveness 12 months post-TKR, and construct validity of the NPS. We performed factor analysis and created subscales from the items loading onto each retained factor. We evaluated subscale properties and calculated the proportion of total scores attributable to each subscale and compared this with the proportion expected if each item contributed equally. Results Mean baseline NPS score among 263 participants was 42.7 (SD: 15.9). Cronbach's alpha was 0.88. Factor analysis produced two factors: “bothersome” (items: intense/sharp/dull/unpleasant/deep; Cronbach's alpha = 0.87), and “dysesthetic” (items: cold/sensitive/itchy/surface; alpha = 0.77). Bothersome items contributed more to total NPS scores (74%) than would be expected if each item contributed equally (50%). NPS scores correlated moderately with baseline pain and function, and decreased after TKR, with standardized response means (SRMs) of: total NPS: 1.77, Bothersome subscale: 2.03, Dysesthetic subscale: 0.70. Conclusions The NPS had acceptable completion, internal consistency, and construct validity, but was not optimal for use in OA; Bothersome subscale items disproportionately drive total NPS scores and may fail to discriminate between nociceptive and neuropathic-like symptoms.

OBJECTIVES: To summarize and appraise any patient-reported or clinician-measured outcome measures based on their measurement properties in proximal humerus fracture patients. DATA SOURCES AND STUDY SELECTION: MEDLINE, EMBASE, and CINAHL were searched from January 2000 to August 2018 to identify all studies of proximal humerus fracture patients that reported a measurement property evaluation of an outcome measure. DATA EXTRACTION AND SYNTHESIS: Quality appraisal of each measure was completed using the Evaluating the Measurement of Patient-Reported Outcomes (EMPRO) tool. The EMPRO takes into account all studies of each measure, and the overall score is transformed linearly to a range of 0 (lowest) to 100 (best). RESULTS: Eleven instruments were identified. Intended concepts of the instruments included clinician-measured shoulder function, patient-reported function or disability, and patient-reported general health state. Only the Disabilities of the Arm, Shoulder and Hand (DASH), Oxford Shoulder Score, Constant Score, University of California, Los Angeles Shoulder Score, and EuroQol 5 Dimension (EQ5D) were evaluated in more than 1 study. The Shoulder Function Index (SFINX), DASH, and EQ5D had the highest EMPRO scores (80, 66, and 58, respectively). The SFINX and DASH consistently scored among the top 3 instruments for each attribute. CONCLUSIONS: Evidence on the measurement properties of outcome measures for proximal humerus fracture patients is limited. With the available evidence, the SFINX is recommended as a clinician-measured functional outcome measure, the DASH as a patient-reported functional outcome measure, and the EQ5D as a general health status measure.
