Background: Clinical management of ventilator-assisted individuals (VAIs) was challenged by social distancing rules during the COVID-19 pandemic. In May 2020, the Long-Term In-Home Ventilator Engagement (LIVE) Program was launched in Ontario, Canada to provide intensive digital care case management to VAIs. The purpose of this qualitative study was to explore the acceptability of the LIVE Program hosted via a digital platform during the COVID-19 pandemic from diverse perspectives., Methods: We conducted a qualitative descriptive study (May 2020-April 2021) comprising semi-structured interviews with participants from eight home ventilation specialty centers in Ontario, Canada. We purposively recruited patients, family caregivers, and providers enrolled in LIVE. Content analysis and the theoretical concepts of acceptability, feasibility, and appropriateness were used to interpret findings., Results: A total of 40 individuals (2 VAIs, 18 family caregivers, 20 healthcare providers) participated. Participants described LIVE as acceptable as it addressed a longstanding imperative to improve care access, ease of use, and training provided; feasible for triaging problems and sharing information; and appropriate for timeliness of provider responses, workflows, and perceived value. Negative perceptions of acceptability among healthcare providers concerned digital workload and fit with existing clinical workflows. Perceived benefits accorded to LIVE included enhanced physical and psychological safety in the home, patient-provider relations, and VAI engagement in their own care., Conclusions: Study findings identify factors influencing the LIVE Program's acceptability by patients, family caregivers, and healthcare providers during pandemic conditions including enhanced access to care, ease of case management triage, and VAI safety. Findings may inform the implementation of digital health services to VAIs in non-pandemic circumstances., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Cryoablation is commonly used in the kidney, lung, breast, and soft tissue, but is an uncommon choice in the liver where radiofrequency ablation (RFA) and microwave ablation (MWA) predominate. This is in part for historical reasons due to serious complications that occurred with open hepatic cryoablation using early technology. More current technology combined with image-guided percutaneous approaches has ameliorated these issues and allowed cryoablation to become a safe and effective thermal ablation modality for treating liver tumors. Cryoablation has several advantages over RFA and MWA including the ability to visualize the ice ball, minimal procedural pain, and strong immunomodulatory effects. This article will review the current literature on cryoablation of primary and secondary liver tumors, with a focus on efficacy, safety, and immunogenic potential. Clinical scenarios when it may be more beneficial to use cryoablation over heat-based ablation in the liver, as well as directions for future research, will also be discussed., Competing Interests: Conflict of Interest None declared., (Thieme.

Background: Guidelines advocate for minimization of physical restraint (PR) use in intensive care units (ICU). Interprofessional team perspectives on PR practices can inform the design and implementation of successful PR minimization interventions., Aim: To identify ICU staff perspectives of contextual influences on PR practices and minimization strategies., Study Design: A qualitative descriptive study in a single ICU in Toronto, Canada. One-on-one semi-structured interviews were conducted with 14 ICU staff. A deductive content analysis of interviews was undertaken using the integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) framework., Results: Five themes were developed: risk-averse culture, leadership, practice monitoring and feedback processes, environmental factors, and facilitation. Participants described a risk-averse culture where prophylactic application of PR for intubated patients was used to prevent unplanned extubation thereby avoiding blame from colleagues. Perceived absence of leadership and interprofessional team involvement situated nurses as the primary decision-maker for restraint application and removal. Insufficient monitoring of restraint practices, lack of access to restraint alternatives, and inability to control environmental contributors to delirium and agitation further increased PR use. Recommendations as to how to minimize restraint use included a nurse facilitator to advance leadership-team collaboration, availability of restraints alternatives, and guidance on situations for applying and removing restraints., Conclusions: This analysis of contextual influences on PR practices and minimization using the i-PARIHS framework revealed potentially modifiable barriers to successful PR minimization, including a lack of leadership involvement, gaps in practice monitoring, and collaborative decision-making processes. A team approach to changing behaviour and culture should be considered for successful implementation and sustainability of PR minimization., Relevance to Practice: The establishment of an interprofessional facilitation team that addresses risk-averse culture and promotes collaboration among ICU stakeholders will be crucial to the success of any approach to restraint minimization., (© 2022 British Association of Critical Care Nurses.)

Background: Continuing professional development is an important means of improving access to effective patient care. Although pain content has increased significantly in prelicensure programs, little is known about how postlicensure health professionals advance or maintain competence in pain management., Aims: The aim of this study was to investigate Canadian health professionals' continuing professional development needs, activities, and preferred modalities for pain management., Methods: This study employed a cross-sectional self-report web survey., Results: The survey response rate was 57% (230/400). Respondents were primarily nurses (48%), university educated (95%), employed in academic hospital settings (62%), and had ≥11 years postlicensure experience (70%). Most patients (>50%) cared for in an average week presented with pain. Compared to those working in nonacademic settings, clinicians in academic settings reported significantly higher acute pain assessment competence (mean 7.8/10 versus 6.9/10; P < 0.002) and greater access to pain specialist consultants (73% versus 29%; P < 0.0001). Chronic pain assessment competence was not different between groups. Top learning needs included neuropathic pain, musculoskeletal pain, and chronic pain. Recently completed and preferred learning modalities respectively were informal and work-based: reading journal articles (56%, 54%), online independent learning (44%, 53%), and attending hospital rounds (43%, 42%); 17% had not completed any pain learning activities in the past 12 months. Respondents employed in nonacademic settings and nonphysicians were more likely to use pocket cards, mobile apps, and e-mail summaries to improve pain management., Conclusions: Canadian postlicensure health professionals require greater access to and participation in interactive and multimodal methods of continuing professional development to facilitate competency in evidence-based pain management., Competing Interests: The authors have no conflicts of interest to report., (© 2023 The Author(s).

Objective: Traumatic brain injury (TBI) has been increasingly linked in population research to psychiatric problems as well as substance use and related harms, suggesting that individuals with TBI may also present more frequently to mental health and addictions (MHA) services. Little is known, however, about TBI history among MHA service users. The objectives of this review were to understand (i) the prevalence of TBI history among MHA service users; (ii) how TBI history is identified in MHA service settings; and (iii) predictors or outcomes of TBI that have been reported in MHA service users., Methods: A scoping review was conducted in accordance with PRISMA Scoping Review Extension guidelines. A search for relevant literature was conducted in MEDLINE, PsycINFO, SPORTDiscus, CINAHL, and Embase as well as various gray literature sources., Results: Twenty-eight relevant studies were identified. TBI was defined and operationalized heterogeneously between studies, and TBI history prevalence rates ranged considerably among the study samples. The included studies used varied methods to identify TBI history in MHA settings, such as clinical chart audits, single-item questions, or structured questionnaires (eg, Brain Injury Screening Questionnaire or Ohio State University TBI Identification Method). TBI history was most consistently associated with indicators of more severe substance use problems and mental health symptoms as well as increased aggression or risk to others. Studies reported less consistent findings regarding the relationship of TBI to physical health, cognitive impairment, functioning, risk to self, and type of psychiatric diagnosis., Conclusion: Screening for TBI history in MHA settings may contribute important information for risk assessment and care planning. However, to be clinically useful, assessment of TBI history will require consistent operationalization of TBI as well as use of validated screening methods., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Purpose: To evaluate how Canadian clinicians involved in trauma patient care and prescribing opioids perceive the use and effectiveness of strategies to prevent long-term opioid therapy following trauma. Barriers and facilitators to the implementation of these strategies were also assessed., Methods: We conducted a web-based cross-sectional survey. Potential participants were identified by trauma program managers and directors of the targeted departments in three Canadian provinces. We designed our questionnaire using standard health survey research methods. The questionnaire was administered between April 2021 and November 2021., Results: Our response rate was 47% (350/744), and 52% (181/350) of participants completed the entire survey. Most respondents (71%, 129/181) worked in teaching hospitals. Multimodal analgesia (93%, 240/257), nonsteroidal anti-inflammatory agents (77%, 198/257), and physical stimulation (75%, 193/257) were the strategies perceived to be the most frequently used. Several preventive strategies were perceived to be very effective by over 80% of respondents. Of these, some that were reported as not being frequently used were perceived to be among the most effective ones, including guidelines or protocols, assessing risk factors for opioid misuse, physical health follow-up by a professional, training for clinicians, patient education, and prescription monitoring systems. Staff shortages, time constraints, and organizational practices were identified as the main barriers to the implementation of the highest ranked preventive strategies., Conclusions: Several strategies to prevent long-term opioid therapy following trauma are perceived as being effective by those prescribing opioids in this population. Some of these strategies appear to be commonly used in everyday practice and others less so. Future research should focus on which preventive strategies should be given higher priority for implementation before assessing their effectiveness., (© 2022. Canadian Anesthesiologists' Society.)

Purpose: Few quality improvement tools specific to patients with persistent or chronic critical illness exist to aid delivery of high-quality care. Using experience-based co-design methods, we sought consensus from key stakeholders on the most important actionable processes of care for inclusion in a quality improvement checklist., Methods: Item generation methods: systematic review, semi-structured interviews (ICU survivors and family) members, touchpoint video creation, and semi-structured interviews (ICU clinicians). Consensus methods: modified online Delphi and a virtual meeting using nominal group technique methods., Results: We enrolled 138 ICU interprofessional team, patients, and family members. We obtained consensus on a quality improvement checklist comprising 11 core domains: patient and family involvement in decision-making; patient communication; physical comfort and complication prevention; promoting self-care and normalcy; ventilator weaning; physical therapy; swallowing; pharmacotherapy; psychological issues; delirium; and appropriate referrals. An additional 27 actionable processes are contained within 6 core domains that provide more specific direction on the actionable process to be targeted., Conclusions: Using a highly collaborative and methodologically rigorous process, we generated a quality improvement checklist of actionable processes to improve patient and family-centred care considered important by key stakeholders. Future research is needed to understand optimal implementation strategies and impact on outcomes and experience., Competing Interests: Declaration of Competing Interest The authors have no declarations of interest to declare., (Copyright © 2022 The Authors.

Introduction: Student perspectives on interprofessional pain education are lacking., Objectives: The purpose of this study was to evaluate ratings of knowledge acquisition and effective presentation methods for prelicensure health professional students attending the University of Toronto Centre for the Study of Pain Interfaculty Pain Curriculum (Canada)., Methods: A 10-year (2009-2019) retrospective longitudinal mixed-methods approach comprising analysis and integration of quantitative and qualitative data sets was used to evaluate 5 core University of Toronto Centre for the Study of Pain Interfaculty Pain Curriculum learning sessions., Results: A total of 10, 693 students were enrolled (2009-2019) with a mean annual attendance of 972 students (±SD:102). The mean proportion of students rating "agree/strongly agree" for knowledge acquisition and effective presentation methods across sessions was 79.3% (±SD:3.4) and 76.7% (±SD:6.0), respectively. Knowledge acquisition or presentation effectiveness scores increased, respectively, over time for 4 core sessions: online self-study pain mechanisms module ( P = 0.03/ P < 0.001), online self-study opioids module ( P = 0.04/ P = 0.019), individually selected in-person topical pain sessions ( P = 0.03/ P < 0.001), and in-person patient or interprofessional panel session ( P = 0.03). Qualitative data corroborated rating scores and expanded insight into student expectations for knowledge acquisition to inform real-world clinical practice and interprofessional collaboration; presentation effectiveness corresponded with smaller session size, individually selected sessions, case-based scenarios, embedded knowledge appraisal, and opportunities to meaningfully interact with presenters and peers., Conclusion: This study demonstrated positive and increasing prelicensure student ratings of knowledge acquisition and effective presentation methods across multifaceted learning sessions in an interfaculty pain curriculum. This study has implications for pain curriculum design aimed at promoting students' collaborative, patient-centered working skills. See commentary: Trouvin A-P.

Context: Critically-ill patients with hematologic malignancies are increasingly admitted to intensive care units globally. Unrelieved symptoms during intensive care treatment may contribute to poor outcomes., Objective: To better understand the symptom experience(s) for critically-ill patients with hematologic malignancies., Methods: A scoping review was conducted searching Medline, CINAHL, PychInfo, Embase, and ProQuest databases, the Cochrane Library, and the grey literature between January 1st, 1990 and July 15th, 2020. Two authors independently reviewed articles for inclusion and verified abstracted data., Results: Seventeen articles met inclusion criteria, including 11 cohort studies, 1 case-control study, and five review articles. No qualitative or mixed-method studies were retrieved. Symptoms were reported as the primary outcome across two studies (17%). Reported hematologic malignancy subtypes included leukemia and/or myelodysplastic syndrome (9, 53%), lymphoma (8, 47%), multiple myeloma (7, 41%), and aplastic anemia (2, 12%). The principal indication for ICU admission was respiratory failure, followed by cardiogenic shock/cardiac failure, endocrine disturbances, sepsis, and neurological failure. Only one study used validated tools for evaluating symptoms. Thirty-four symptoms were reported: altered level of consciousness/coma (35%); diarrhea (35%); nausea (35%); dyspnea (35%); vomiting (29%); and pain (29%). Two articles (13%) identified symptom clusters., Conclusion: There is minimal research that measures and explores the symptom experiences of critically-ill patients with hematologic malignancies. New research in this domain is needed to inform targeted symptom care for this vulnerable patient population., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Background: Despite expert recommendations for use, limited evidence identifies effectiveness of mechanical insufflation-exsufflation (MI-E) in addressing respiratory morbidity and resultant health care utilization and costs for individuals with neuromuscular disorders. We examined the impact of provision of publicly funded MI-E devices on health care utilization, health care costs, and survival trajectory., Methods: This is a retrospective pre/post cohort study linking data on prospectively recruited participants using MI-E to health administrative databases to quantify outcomes., Results: We linked data from 106 participants (8 age < 15 y) and determined annualized health care use pre/post device. We found no difference in emergency department (ED) visit or hospital admission rates. Following MI-E approval, participants required fewer hospital days (median [interquartile range] [IQR]) 0 [0-9] vs 0 [0-4], P = .03). Rates of physician specialist visits also decreased (median IQR 7 [4-11] vs 4 [2-7], P < .001). Conversely, rates of home care nursing and homemaking/personal support visits increased. Following MI-E, total costs were lower for 59.4%, not different for 13.2%, and higher for 27.4%. Physician billing costs decreased whereas home care costs increased. Regression modeling identified pre-MI-E costs were the most important predictor of costs after approval. At 12 months, 23 (21.7%) participants had died. Risk of death was higher for those using more medical devices (hazard ratio 1.12, [95% CI 1.02-1.22]) in the home., Conclusions: Provision of publicly funded MI-E devices did not influence rates of ED visits or hospital admission but did shift health care utilization and costs from the acute care to community sector. Although increased community costs negated cost savings from physician billings, evidence suggests costs savings from reduced hospital days and fewer specialist visits. Risk of death was highest in individuals requiring multiple medical technologies., Competing Interests: The authors disclose a relationship with IQVIA Canada., (Copyright © 2022 by Daedalus Enterprises.)

Introduction: Delivery of interprofessional pain education for prelicensure healthcare professionals is strongly recommended to advance a workforce ready for collaborative practice and to improve the quality and outcomes of pain care., Objectives: We report a 10-year (2009-2019) longitudinal evaluation of a 20-hour undergraduate Interfaculty Pain Curriculum (IPC) delivered to students in the Faculties of Dentistry, Nursing, Pharmacy, and Medicine (also including the Departments of Physical Therapy, Occupational Therapy and Physician Assistant) at the University of Toronto, Canada. The IPC follows a constructivist approach to facilitate interactive and multifaceted learning., Methods: Evaluation methods based on the Kirkpatrick model were used to appraise changes in participating students' pain knowledge and beliefs and their ability to collaboratively develop an interprofessional pain management plan., Results: A total of 10,693 students participated over the 10-year study period. The mean annual attendance was 972 students and participation to the program increased significantly over the years. Overall, the IPC was effective in improving students' mean pain knowledge and beliefs scores; however, the mean knowledge score gains were negatively correlated with time, likely related to increased uniprofessional pain education. Although an increasing trend in mean interprofessional pain management plan scores was observed, the scores were not significantly correlated with time., Conclusions: The interactive and multifaceted IPC is consistently effective in improving knowledge and beliefs and interprofessional pain management care plan development among participating student cohorts. Future inquiry is required to better understand the mechanisms behind student learning in interprofessional pain education to enhance pain curriculum development and delivery., Competing Interests: The authors have no conflicts of interest to declare.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2021 The Author(s).

Purpose: Oral chlorhexidine is used widely for mechanically ventilated patients to prevent pneumonia, but recent studies show an association with excess mortality. We examined whether de-adoption of chlorhexidine and parallel implementation of a standardized oral care bundle reduces intensive care unit (ICU) mortality in mechanically ventilated patients., Methods: A stepped wedge cluster-randomized controlled trial with concurrent process evaluation in 6 ICUs in Toronto, Canada. Clusters were randomized to de-adopt chlorhexidine and implement a standardized oral care bundle at 2-month intervals. The primary outcome was ICU mortality. Secondary outcomes were time to infection-related ventilator-associated complications (IVACs), oral procedural pain and oral health dysfunction. An exploratory post hoc analysis examined time to extubation in survivors., Results: A total of 3260 patients were enrolled; 1560 control, 1700 intervention. ICU mortality for the intervention and control periods were 399 (23.5%) and 330 (21.2%), respectively (adjusted odds ratio [aOR], 1.13; 95% confidence interval [CI] 0.82 to 1.54; P = 0.46). Time to IVACs (adjusted hazard ratio [aHR], 1.06; 95% CI 0.44 to 2.57; P = 0.90), time to extubation (aHR 1.03; 95% CI 0.85 to 1.23; P = 0.79) (survivors) and oral procedural pain (aOR, 0.62; 95% CI 0.34 to 1.10; P = 0.10) were similar between control and intervention periods. However, oral health dysfunction scores (- 0.96; 95% CI - 1.75 to - 0.17; P = 0.02) improved in the intervention period., Conclusion: Among mechanically ventilated ICU patients, no benefit was observed for de-adoption of chlorhexidine and implementation of an oral care bundle on ICU mortality, IVACs, oral procedural pain, or time to extubation. The intervention may improve oral health., (© 2021. Springer-Verlag GmbH Germany, part of Springer Nature.)

Background: Inability to communicate in a manner that can be understood causes extreme distress for people requiring an artificial airway and has implications for care quality and patient safety. Options for aided communication include non-vocal, speech-generating, and voice-enabling aids., Objectives: To assess effectiveness of communication aids for people requiring an artificial airway (endotracheal or tracheostomy tube), defined as the proportion of people able to: use a non-vocal communication aid to communicate at least one symptom, need, or preference; or use a voice-enabling communication aid to phonate to produce at least one intelligible word. To assess time to communication/phonation; perceptions of communication; communication quality/success; quality of life; psychological distress; length of stay and costs; and adverse events., Search Methods: We searched the Cochrane Library (Wiley version), MEDLINE (OvidSP), Embase (OvidSP), three other databases, and grey literature from inception to 30 July 2020., Selection Criteria: We included randomised controlled trials (RCTs), quasi-RCTs, cluster-RCTs, controlled non-randomised parallel group, and before-after studies evaluating communication aids used in adults with an artificial airway., Data Collection and Analysis: We used standard methodological procedures recommended by Cochrane. Two review authors independently performed data extraction and assessment of risk of bias., Main Results: We included 11 studies (1931 participants) conducted in intensive care units (ICUs). Eight evaluated non-vocal communication aids and three voice-enabling aids. Usual care was the comparator for all. For six studies, this comprised no aid; usual care in the remaining five studies comprised use of various communication aids. Overall, our confidence in results regarding effectiveness of communication interventions was very low due to imprecision, measurement heterogeneity, inconsistency in results, and most studies at high or unclear risk of bias across multiple domains. No non-vocal aid studies reported our primary outcome. We are uncertain of the effects of early use of a voice-enabling aid compared to routine use on ability to phonate at least one intelligible word (risk ratio (RR) 3.03, 95% confidence interval (CI) 0.18 to 50.08; 2 studies; very low-certainty evidence). Compared to usual care without aids, we are uncertain about effects of a non-vocal aid (communication board) on patient satisfaction (standardised mean difference (SMD) 2.92, 95% CI 1.52 to 4.33; 4 studies; very low-certainty evidence). No studies of non-vocal aids reported quality of life. Low-certainty evidence from two studies suggests early use of a voice-enabling aid may have no effect on quality of life (MD 2.27, 95% CI -7.21 to 11.75). Conceptual differences in measures of psychological distress precluded data pooling; however, intervention arm participants reported less distress suggesting there might be benefit, but our certainty in the evidence is very low. Low-certainty evidence suggest voice-enabling aids have little or no effect on ICU length of stay; we were unable to determine effects of non-vocal aids. Three studies reported different adverse events (physical restraint use, bleeding following tracheostomy, and respiratory parameters indicating respiratory decompensation). Adverse event rates were similar between arms in all three studies. However, uncertainty remains as to any harm associated with communication aids., Authors' Conclusions: Due to a lack of high-quality studies, imprecision, inconsistency of results, and measurement heterogeneity,  the evidence provides insufficient information to guide practice as to which communication aid is more appropriate and when to use them. Understanding effectiveness of communication aids would benefit from development of a core outcome measurement set., (Copyright © 2021 The Cochrane Collaboration.

Introduction: Patients requiring invasive mechanical ventilation via an artificial airway experience sudden voicelessness placing them at risk for adverse outcomes and increasing provider workload. Infection control precautions during the COVID-19 pandemic, including the use of personal protective equipment (eg, gloves, masks, etc), patient isolation, and visitor restrictions may exacerbate communication difficulty. The objective of this study is to evaluate the acceptability of a codesigned communication intervention for use in the adult intensive care unit when infection control precautions such as those used during COVID-19 are required., Methods and Analysis: This three-phased, prospective study will take place in a medical surgical ICU in a community teaching hospital in Toronto. Participants will include ICU healthcare providers, adult patients and their family members. Qualitative interviews (target n: 20-25) will explore participant perceptions of the barriers to and facilitators for supporting patient communication in the adult ICU in the context of COVID-19 and infection control precautions (phase 1). Using principles of codesign, a stakeholder advisory council of 8-10 participants will iteratively produce an intervention (phase 2). The codesigned intervention will then be implemented and undergo a mixed method acceptability evaluation in the study setting (phase 3). Acceptability, feasibility and appropriateness will be evaluated using validated measures (target n: 60-65). Follow-up semistructured interviews will be analysed using the theoretical framework of acceptability (TFA). The primary outcomes of this study will be acceptability ratings and descriptions of a codesigned COmmunication intervention for use during and beyond the COVID-19 PandEmic., Ethics and Dissemination: The study protocol has been reviewed, and ethics approval was obtained from the Michael Garron Hospital. Results will be made available to healthcare providers in the study setting throughout the study and through publications and conference presentations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background: Pain assessment in brain-injured patients in the intensive care unit (ICU) is challenging and existing scales may not be representative of behavioral reactions expressed by this specific group. This study aimed to validate the French-Canadian and English revised versions of the Critical-Care Pain Observation Tool (CPOT-Neuro) for brain-injured ICU patients., Methods: A prospective cohort study was conducted in three Canadian and one American sites. Patients with a traumatic or a non-traumatic brain injury were assessed with the CPOT-Neuro by trained raters (i.e., research staff and ICU nurses) before, during, and after nociceptive procedures (i.e., turning and other) and non-nociceptive procedures (i.e., non-invasive blood pressure, soft touch). Patients who were conscious and delirium-free were asked to provide their self-report of pain intensity (0-10). A first data set was completed for all participants (n = 226), and a second data set (n = 87) was obtained when a change in the level of consciousness (LOC) was observed after study enrollment. Three LOC groups were included: (a) unconscious (Glasgow Coma Scale or GCS 4-8); (b) altered LOC (GCS 9-12); and (c) conscious (GCS 13-15)., Results: Higher CPOT-Neuro scores were found during nociceptive procedures compared to rest and non-nociceptive procedures in both data sets (p < 0.001). CPOT-Neuro scores were not different across LOC groups. Moderate correlations between CPOT-Neuro and self-reported pain intensity scores were found at rest and during nociceptive procedures (Spearman rho > 0.40 and > 0.60, respectively). CPOT-Neuro cut-off scores ≥ 2 and ≥ 3 were found to adequately classify mild to severe self-reported pain ≥ 1 and moderate to severe self-reported pain ≥ 5, respectively. Interrater reliability of raters' CPOT-Neuro scores was supported with intraclass correlation coefficients > 0.69., Conclusions: The CPOT-Neuro was found to be valid in this multi-site sample of brain-injured ICU patients at various LOC. Implementation studies are necessary to evaluate the tool's performance in clinical practice.

Background: In 2014, the Ministry of Health of Ontario, Canada, approved a program of public funding for specialist-prescribed mechanical insufflation-exsufflation (MI-E) devices for home use by individuals with neuromuscular respiratory insufficiency. Since 2014, 1,926 MI-E devices have been provided, exceeding device-use projections. Few studies describe the initial and ongoing education and support needs of home MI-E users and their family caregivers. This study aimed to explore the requirements of initial and ongoing education and support for MI-E device use, user confidence, and barriers and facilitators to home MI-E., Methods: We conducted semi-structured interviews with new (< 6 months) and established (6-48 months) MI-E users and family caregivers. Device users rated their confidence on a numeric rating scale of 1 (not confident) to 10 (very confident)., Results: We recruited 14 new and 14 established MI-E users and caregivers (including 9 dyads), and we conducted 28 interviews. Both new and established users were highly confident in use of MI-E (mean ± SD scores were 8.8 ± 1.2 and 8.3 ± 2.1, respectively). Overall, the subjects were satisfied with their initial education, which consisted of a 1-2 h one-on-one session at home or in the clinic with a device demonstration and hands-on practice. Subjects viewed hands-on practice and teaching of caregivers as more beneficial than written materials. Ongoing support for device use was variable. Most subjects indicated a lack of specific follow-up, which resulted in uncertainty about whether they were using the MI-E device correctly or whether MI-E was effective. Facilitators to device utilization were ease of use, initial training, support from formal or informal caregivers, and symptom relief. Barriers were inadequate education on MI-E purpose, technique, and benefit; lack of follow-up; and inadequate knowledge of MI-E by nonspecialist health providers., Conclusions: The current model of home MI-E education at initiation meets user and caregiver needs. Better ongoing education and follow-up are needed to sustain the benefits through assessment of MI-E technique and its effectiveness., Competing Interests: This study was supported by a grant from the International Ventilator Users Network.

Objectives: To assess the nature, quality and independence of scientific evidence provided in support of claims in industry-authored educational materials in oral health., Design: A content analysis of educational materials authored by the four major multinational oral health product manufacturers., Setting: Acute care settings., Participants: 68 documents focused on oral health or oral care, targeted at acute care clinicians and identified as 'educational' on companies' international websites., Main Outcome Measures: Data were extracted in duplicate for three areas of focus: (a) products referenced in the documents, (b) product-related claims and (c) citations substantiating claims. We assessed claim-citation pairs to determine if information in the citation supported the claim. We analysed the inter-relationships among cited authors and companies using social network analysis., Results: Documents ranged from training videos to posters to brochures to continuing education courses. The majority of educational materials explicitly mentioned a product (59/68, 87%), a branded product (35/68, 51%), and made a product-related claim (55/68, 81%). Among claims accompanied by a citation, citations did not support the majority (91/147, 62%) of claims, largely because citations were unrelated. References used to support claims most often represented lower levels of evidence: only 9% were systematic reviews (7/76) and 13% were randomised controlled trials (10/76). We found a network of 20 authors to account for 37% (n=77/206) of all references in claim-citation pairs; 60% (12/20) of the top 20 cited authors received financial support from one of the four sampled manufacturers., Conclusions: Resources to support clinicians' ongoing education are scarce. However, caution should be exercised when relying on industry-authored materials to support continuing education for oral health. Evidence of sponsorship bias and reliance on key opinion leaders suggests that industry-authored educational materials have promotional intent and should be regulated as such., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

We explore the intergenerational pattern of resource transfer and possible associated factors. A scoping review was conducted of quantitative, peer-reviewed, English-language studies related to intergenerational transfer or interaction. We searched AgeLine, PsycINFO, Social Work Abstracts, and Sociological Abstracts for articles published between Jane 2008 and December 2018. Seventy-five studies from 25 countries met the inclusion criteria. The scoping review categorised resource transfers into three types: financial, instrumental, and emotional support. Using an intergenerational solidarity framework, factors associated with intergenerational transfer were placed in four categories: (1) demographic factors (e.g., age, gender, marital status, education, and ethno-cultural background); (2) needs and opportunities factors, including health, financial resources, and employment status; (3) family structures, namely, family composition, family relationship, and earlier family events; and (4) cultural-contextual structures, including state policies and social norms. Those factors were connected to the direction of resource transfer between generations. Downward transfers from senior to junior generations occur more frequently than upward transfers in many developed countries. Women dominate instrumental transfers, perhaps influenced by traditional gender roles. Overall, the pattern of resource transfer between generations is shown, and the impact of social norms and social policy on intergenerational transfers is highlighted. Policymakers should recognise the complicated interplay of each factor with different cultural contexts. The findings could inform policies that strengthen intergenerational solidarity and support.

Background : Intubated and mechanically ventilated patients in the intensive care unit (ICU) may experience pain during routine oral procedures such as oral suctioning and tooth brushing. Despite the importance of pain prevention and management, little is known about patients' experiences of procedural oral pain. Aims : The aim of this study was to explore patients' recollections and recommendations for pain and discomfort during routine oral procedures. Methods : A qualitative descriptive design was used. Adult patients were recruited from a mixed medical-surgical-trauma ICU in an academic hospital in Toronto, Canada. Participants were interviewed using object elicitation methods within 7 days of discharge from the ICU. Data were analyzed using directed content analysis methods. Results : We recruited 33 participants who were primarily male (23, 70%), with an average age of 54 (SD = 18) years, admitted with a medical (13, 39%), trauma (11, 33%), or surgical (9, 27%) diagnosis and dentate (27, 82%). Most participants described oral procedures as painful, discomforting, and emotionally distressing. Identified sources of pain included dry, inflamed oral tissues and procedural technique. Procedural pain behaviors were perceived to be frequently misinterpreted by clinicians as agitation, with consequences including physical restraint and unrelieved suffering. Participants advocated for greater frequency of oral care to prevent oral health deterioration, anticipatory procedural guidance, and structured pain assessment to mitigate the dehumanizing experience of unmanaged pain. Conclusions : Patients described routine oral care procedures as painful and recalled suboptimal management of such pain. Procedural oral pain is an important target for practice improvement., Competing Interests: The authors have no conflicts of interest to declare., (© 2020 The Author(s).

Background : Pain is a significant problem in adults living with advanced liver disease, having limited guidance available for its clinical management. While pain is considered a multidimensional experience, there have been limited reviews of the pain literature in advanced liver disease conducted with a multidimensional framework. Aims: The goal of this scoping review was to identify and map the multidimensional domains of pain in adults with advanced liver disease using the biopsychosocial model. Methods: We used Arksey and O'Malley's scoping framework. A search was conducted in MEDLINE, Embase, AMED, and CINAHL databases and the gray literature using specific eligibility criteria (1990-2019). Citation selection and data extraction were performed by two independent reviewers and in duplicate. Results: Of the 43 studies that met inclusion criteria, 51% were from North America and 93% utilized quantitative methods. The combined studies reported on 168,110 participants with ages ranging between 23 to 87 years. Only 9% reported an objective scoring system for liver disease severity. Few studies reported pain classification (9%) and intensity (16%). Pain prevalence ranged between 18% and 100%, with pain locations including joint, abdomen, back, head/neck, and upper/lower extremities. We identified and mapped 115 pain factors to the biopsychosocial model: physical (81%), psychological (65%), and sociocultural (5%). Only 9% measured pain using validated multidimensional tools. Pharmacological intervention (92%) prevailed among pain treatments. Conclusions: Pain is not well understood in patients with advanced liver disease, having limited multidimensional pain assessment and treatment approaches. There is a need to systematically examine the multidimensional nature of pain in this population., Competing Interests: Franklin Gorospe does not have any conflicts of interest. Laura Istanboulian does not have any conflicts of interest. Dr. Martine Puts does not have any conflicts of interest. Dr. David Wong does not have any conflicts of interest.

Objectives: Family caregivers of patients requiring prolonged mechanical ventilation may experience physical and psychological morbidity associated with a protracted intensive care unit experience. Our aim was to explore potentially modifiable support needs and care processes of importance to family caregivers of patients requiring prolonged mechanical ventilation and transition from the intensive care unit to a specialised weaning centre., Research Methodology/design: A longitudinal qualitative descriptive interview study. Data was analysed using directed content analysis., Setting: A 6-bed specialised weaning centre in Toronto, Canada., Findings: Eighteen family caregivers completed interviews at weaning centre admission (100%), and at two-weeks (40%) and three-months after discharge (22%) contributing 29 interviews. Caregivers were primarily women (61%) and spouses (50%). Caregivers perceived inadequate informational, emotional, training, and appraisal support by health care providers limiting understanding of prolonged ventilation, participation in care and decision-making, and readiness for weaning centre transition. Participants reported long-term physical and psychological health changes including alterations to sleep, energy, nutrition and body weight., Conclusions: Deficits in informational, emotional, training, and appraisal support of family caregivers of prolonged mechanical ventilation patients may increase caregiver burden and contribute to poor health outcomes. Strategies for providing support and maintaining family caregiver health-related quality of life are needed., (Copyright © 2020 Elsevier Ltd. All rights reserved.)

Aim: To explore descriptors of difficulty accessing the mouths of intubated and mechanically ventilated adults for oral care, consequences, modifiable antecedents and recommendations for improving care delivery., Background: Nurses report oral access and care delivery difficulty in most mechanically ventilated patients., Design: A prospective qualitative descriptive design., Methods: Data were collected using video and photographic elicitation interviews focused on delivery of oral care. Directed content analysis was used to explore descriptive categories. Reporting used the SRQR guidelines., Setting and Participants: A university-affiliated hospital in Toronto, Canada. Participants included clinicians experienced in accessing the oral space of adults representing nursing, medicine, dentistry and allied health professionals., Findings: We recruited 18 participants; 9 representing critical care and 9 other specialties frequently accessing the mouth, that is dentistry. Descriptors for observed difficulty accessing the oral cavity were "oral crowding with tubes" and "aversive patient responses", which were considered to result in insufficient oral care. Participants perceived aversive patient responses (e.g. biting, turning head side to side, gagging, coughing) as a consequence of forced introduction of instruments inside a crowded mouth. A key finding identified by participants was the observation of substantial procedural pain during oral care interventions. Potentially modifiable antecedents to difficult oral care delivery identified were procedural pain, oral health deterioration (e.g. xerostomia) and lack of interprofessional team problem-solving. Recommendations to address these antecedents included patient preparation for oral care through verbal and nonverbal cueing, pharmacological and nonpharmacological strategies, and ICU interprofessional education., Conclusions: Oral care in mechanically ventilated adults is complex and painful. Visual research methods offer important advantages for oral care exploration including its ability to reveal less visible aspects of the nurse-patient encounter, thereby enabling novel insights and care., Relevance for Clinical Practice: Interprofessional education and training in oral health and care interventions tailored to mechanically ventilated patients are recommended., (© 2019 John Wiley & Sons Ltd.)

Purpose: To identify barriers and facilitators for the use of augmentative and alternative communication (AAC) and voice restorative strategies for adult patients with an advanced airway in the intensive care unit (ICU)., Materials and Methods: Scoping review searching five databases between 1990 and 2019. We screened 13, 167 citations and included all study types reporting barriers and/or facilitators to using communication strategies in an ICU setting. Two authors independently extracted and coded reported barriers and facilitators to the Theoretical Domains Framework (TDF) domains., Results: Of the 44 studies meeting inclusion criteria 18 (44%) used qualitative, 18 (44%) used quantitative, and 8 (18%) used mixed methods. In total, 39 unique barriers and 46 unique facilitators were identified and coded to the domains of the TDF. Barriers were most frequently coded to the Skills, Environmental Context and Resources, and Emotion domains. Facilitators were most frequently coded to Reinforcement, Environmental Context and Resources, and Social and Professional Roles/Identity domains. Thematic synthesis produced four potentially modifiable factors: context, emotional support, training, and decisional algorithms., Conclusions: Identified barriers (skills, environment, resources, emotions) and facilitators (reinforcement, resources, roles) to ICU communication strategy use in the literature may be modified through formal training and role support., Competing Interests: Declaration of Competing Interest The authors declare no competing interests other than authorship of an included study (Rose et al., 2018)., (Copyright © 2020 Elsevier Inc.

Objective: Adolescents receiving long-term home mechanical ventilation (HMV) who survive into adulthood must transition to adult health care services. Lack of transition readiness is reported to result in poor health outcomes. The objective of this study is to explore longitudinally the pediatric-to-adult health care transition experience involving a transition program for adolescents receiving HMV including transition readiness, barriers, facilitators, and modifiable features., Design: A prospective qualitative longitudinal interview study of adolescent and family caregiver dyads recruited through a pediatric-to-adult HMV transition program jointly established by two collaborating health centers: The Hospital for Sick Children and West Park Healthcare Centre in Toronto, Canada. Eligible dyads were interviewed at three time points: pretransition, transition, and 12-months posttransition. Interviews were transcribed verbatim and analyzed using directed content analysis methods., Results: Ventilator-assisted adolescents (VAAs) and caregiver participants perceived a lack of transition readiness in their ability to manage health communication and coordination across multiple adult providers. Transition facilitators included early transition discussion, opportunities for VAAs to speak directly with HMV providers during appointments, receipt of print informational materials regarding adult services, and a joint pediatric-adult team handover meeting. Modifiable transition barriers included lack of other specialist referrals, insufficient information about adult homecare service funding, and limited involvement of family doctors. Unresolved transition barriers resulted in perceptions of service fragmentation., Conclusions: Although the pediatric-to-adult HMV transition program conferred benefits service fragmentation was perceived. Transition barriers may be overcome through early planning and staged transition with all specialists, community providers, and the family and adolescent working in collaboration., (© 2020 Wiley Periodicals, Inc.)

Background: Routine application of chlorhexidine oral rinse is recommended to reduce risk of ventilator-associated pneumonia (VAP) in mechanically ventilated patients. Recent reappraisal of the evidence from two meta-analyses suggests chlorhexidine may cause excess mortality in non-cardiac surgery patients and does not reduce VAP. Mechanisms for possible excess mortality are unclear. The CHORAL study will evaluate the impact of de-adopting chlorhexidine and implementing an oral care bundle (excluding chlorhexidine) on mortality, infection-related ventilator-associated complications (IVACs), and oral health status., Methods: The CHORAL study is a stepped wedge, cluster randomized controlled trial in six academic intensive care units (ICUs) in Toronto, Canada. Clusters (ICU) will be randomly allocated to six sequential steps over a 14-month period to de-adopt oral chlorhexidine and implement a standardized oral care bundle (oral assessment, tooth brushing, moisturization, and secretion removal). On study commencement, all clusters begin with a control period in which the standard of care is oral chlorhexidine. Clusters then begin crossover from control to intervention every 2 months according to the randomization schedule. Participants include all mechanically ventilated adults eligible to receive the standardized oral care bundle. The primary outcome is ICU mortality; secondary outcomes are IVACs and oral health status. We will determine demographics, antibiotic usage, mortality, and IVAC rates from a validated local ICU clinical registry. With six clusters and 50 ventilated patients on average each month per cluster, we estimate that 4200 patients provide 80% power after accounting for intracluster correlation to detect an absolute reduction in mortality of 5.5%. We will analyze our primary outcome of mortality using a generalized linear mixed model adjusting for time to account for secular trends. We will conduct a process evaluation to determine intervention fidelity and to inform interpretation of the trial results., Discussion: The CHORAL study will inform understanding of the effectiveness of de-adoption of oral chlorhexidine and implementation of a standardized oral care bundle for decreasing ICU mortality and IVAC rates while improving oral health status. Our process evaluation will inform clinicians and decision makers about intervention delivery to support future de-adoption if justified by trial results., Trial Registration: ClinicalTrials.gov, NCT03382730 .

Purpose: Liquid biopsies that noninvasively detect molecular correlates of aggressive prostate cancer (PCa) could be used to triage patients, reducing the burdens of unnecessary invasive prostate biopsy and enabling early detection of high-risk disease. DNA hypermethylation is among the earliest and most frequent aberrations in PCa. We investigated the accuracy of a six-gene DNA methylation panel (Epigenetic Cancer of the Prostate Test in Urine [epiCaPture]) at detecting PCa, high-grade (Gleason score greater than or equal to 8) and high-risk (D'Amico and Cancer of the Prostate Risk Assessment] PCa from urine., Patients and Methods: Prognostic utility of epiCaPture genes was first validated in two independent prostate tissue cohorts. epiCaPture was assessed in a multicenter prospective study of 463 men undergoing prostate biopsy. epiCaPture was performed by quantitative methylation-specific polymerase chain reaction in DNA isolated from prebiopsy urine sediments and evaluated by receiver operating characteristic and decision curves (clinical benefit). The epiCaPture score was developed and validated on a two thirds training set to one third test set., Results: Higher methylation of epiCaPture genes was significantly associated with increasing aggressiveness in PCa tissues. In urine, area under the receiver operating characteristic curve was 0.64, 0.86, and 0.83 for detecting PCa, high-grade PCa, and high-risk PCa, respectively. Decision curves revealed a net benefit across relevant threshold probabilities. Independent analysis of two epiCaPture genes in the same clinical cohort provided analytical validation. Parallel epiCaPture analysis in urine and matched biopsy cores showed added value of a liquid biopsy., Conclusion: epiCaPture is a urine DNA methylation test for high-risk PCa. Its tumor specificity out-performs that of prostate-specific antigen (greater than 3 ng/mL). Used as an adjunct to prostate-specific antigen, epiCaPture could aid patient stratification to determine need for biopsy., Competing Interests: AUTHORS’ DISCLOSURES OF POTENTIAL CONFLICTS OF INTEREST The following represents disclosure information provided by authors of this manuscript.

Objective: Mechanically ventilated patients experience pain at rest and during daily care procedures. Our objective was to test the reliability and validity of the Critical-Care Pain Observation Tool (CPOT) to detect oral-pharyngeal pain in intubated and tracheostomised adults during routine oral care procedures., Materials and Methods: Two trained research team members independently observed patients during two non-painful (rest and gentle touch) and three potentially painful (oral suctioning, tooth brushing, and swabbing with a sponge toothette) procedures. Conscious patients were asked if they experienced pain during each procedure (yes/no) and to rate their pain intensity on a 0 to 10 numeric rating scale., Results: A total of 98 patients, primarily intubated (92.9%) and male (63.3%) participated. Criterion validation was supported by patient self-report of pain during tooth brushing (AUC=.80; P<0.5) and oral suction (AUC=.72; P<0.3) but not for oral swabbing (AUC=.68; P=0.16). Discriminative validation was demonstrated for all oral care procedures compared to rest (P<.001). Intra-class correlation coefficients between raters ranged from .78 to .91 (P<.001) for total CPOT scores, indicating excellent inter-rater reliability., Conclusions: The CPOT is reliable and valid for the detection of oral-pharyngeal pain during oral care procedures indicated as painful by critically ill adults., (Copyright © 2018 The Authors.

Background: Oral care of intubated patients is essential to the prevention of infection and patient discomfort. However, barriers to oral access and delivery of oral care have received little attention., Objective: To determine prevalence and predictors of oral access difficulty., Design: A prospective, observational, multi-center study., Settings: Four intensive care units in Toronto, Canada., Participants: Adult patients orally intubated for ≥48 h., Methods: We screened consecutive admissions once a week to identify eligible participants. We observed each patient and asked the patient's nurse about presence or absence of difficulty accessing the mouth to deliver oral care across three categories: (1) visualizing inside the mouth; (2) obtaining patient cooperation, or (3) inserting instruments for delivery of oral care. We asked nurses to identify presence of patient behaviors contributing to oral access difficulty and perceived level of difficulty on a Likert response scale. We examined patient and treatment characteristics associated with extreme difficulty (i.e., difficulty in all 3 categories) using a generalized estimating equation regression model., Results: A total of 428 patients were observed, 58% admitted with a medical diagnosis. More than half (57%) had ≥2 oral devices up to maximum of 4. Oral care difficulty was identified in 83% of patients and rated as moderate to high for 217 (51%). Difficulty concerned visibility (74%), patient cooperation (55%), and space to insert instruments (53%). Patient behaviors contributing difficulty included coughing/gagging (60%), mouth closing (49%), biting (45%) and localizing (27%) during care. Variables associated with extreme difficulty included neurological (OR 1.92, 95% CI 1.42-2.60) or trauma admission (OR 1.83, 95% CI 1.16-2.89), lack of pain assessment or treatment in the 4 h prior to oral care (OR 1.43, 95% CI 1.14-1.80), more oral devices (OR 1.40, 95% CI 1.05-1.87), and duration of intubation (OR 1.05, 95% CI 1.01-1.10). Absence of documented agitation in the 4 h prior to oral care was associated with less difficulty (OR 0.68, 95% CI 0.54-0.86)., Conclusions: Oral care is complex and difficulties are experienced in a vast majority of intubated patients. Some difficulties are amenable to correction such as pain management., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Background: Habitual practices are challenged by chronic illness. Cardiac rehabilitation (CR) involves changes to habits of diet, activity and tobacco use, and although it is effective for people with diabetes and cardiovascular disease (CVD), some participants are reportedly less likely to complete programs and adopt new health related practices. Within the first three months of enrolling in CR, attrition rates are highest for women and for people with diabetes. Previous studies and reviews indicate that altering habits is very difficult, and the social significance of such change requires further study., Purpose: The purpose of the study was to use Bourdieu's concepts of habitus, capital and field to analyse the complexities of adopting new health practices within the first three months after enrolling in a CR program. We were particularly interested in gender issues., Methods: Thirty-two men and women with diabetes and CVD were each interviewed twice within the first three months of their enrolment in one of three CR programs in Toronto, Canada., Results: Attention to CR goals was not always the primary consideration for study participants. Instead, a central concern was to restore social dignity within other fields of activity, including family, friendships, and employment. Thus, study participants evolved improvised tactical approaches that combined both physical and social rehabilitation. These improvised tactics were socially embedded and blended new cultural capital with existing (often gendered) cultural capital and included: concealment, mobilizing cooperation, re-positioning, and push-back., Conclusions: Our findings suggest that success in CR requires certain baseline levels of capital - including embodied, often gendered, cultural capital - and that efforts to follow CR recommendations may alter social positioning., (Copyright © 2018 Elsevier Ltd.

Purpose: No studies have explored the experiences of Canadian mechanical ventilator-assisted adolescents (VAAs) living at home as they transition from paediatric to adult health providers. A better understanding of the needs of this growing population is essential to provide transition services responsive to VAAs and caregiver-identified needs., Methods: We conducted semistructured telephone interviews with adolescents and family caregivers who had recently initiated or completed transition to adult care recruited from three Canadian university-affiliated paediatric home ventilation programs. We analyzed transcripts using a theoretical framework for understanding facilitators and barriers to transition., Results: We interviewed 18 individuals representing 14 episodes of paediatric to adult transition. Participants identified early planning, written informational materials and joint paediatric-adult provider-family transition meetings as facilitators of care transition to adult services and providers. Barriers included insufficient information, limited access to interprofessional (nursing and allied health) providers and reduced funding or health services. Barriers resulted in service disruption and a sense of 'medical homelessness'. While most families related a positive transition to a new 'medical home', families caring for VAAs with moderate-to-severe cognitive and/or physical dependence more commonly reported transition difficulties., Conclusions: Important opportunities exist to enable improvements in the transition experiences of VAAs and their family caregivers. To maximize service continuity during paediatric to adult transition, future research should focus on transition navigator roles, interprofessional health outreach and the needs of families caring for VAAs with cognitive and physical deficits.

Rationale: Predictions about neurologic prognosis that are based on early clinical findings after out-of-hospital cardiac arrest (OHCA) are often inaccurate and may lead to premature decisions to withdraw life-sustaining treatments (LST) in patients who might otherwise survive with good neurologic outcomes., Objectives: To improve adherence to recommendations for appropriate neurologic prognostication after OHCA and reduce deaths from premature decisions to withdraw LST., Methods: This was a pragmatic stepped wedge cluster randomized controlled trial evaluating a multifaceted quality intervention (education, pathways, local champions, audit-feedback). The primary outcome was appropriate neurologic prognostication, defined as (1a) no early withdrawal of LST (WLST) (within 72 h) based on estimates of poor neurologic prognosis and (1b) no WLST between 72 hours and 7 days in absence of clinical predictors of poor neurologic prognosis or (2) surviving beyond 7 days. Secondary outcomes were deaths from early WLST and survival with good neurologic outcome., Measurements and Main Results: Between June 1, 2011, and June 30, 2014, a total of 905 patients with OHCA were enrolled from ICUs of 18 Ontario hospitals. Rates of appropriate neurologic prognostication increased after the intervention (68% vs. 74% patients; odds ratio [OR], 1.79; 95% confidence interval [CI], 1.01-3.19; P = 0.05). However, rates of survival to hospital discharge (46% vs. 50%; OR, 1.71; 95% CI, 0.97-3.01; P = 0.06) and survival with good neurologic outcome remained similar (38% vs. 43%; OR, 1.43; 95% CI, 0.84-2.86; P = 0.19)., Conclusions: A multicenter quality intervention improved rates of appropriate neurologic prognostication after OHCA but did not increase survival with good neurologic outcome. Clinical trial registered with www.clinicaltrials.gov (NCT 01472458).

Rationale: Early withdrawal of life-sustaining therapy contributes to the majority of deaths following out-of-hospital cardiac arrest (OHCA), despite current recommendations for delayed neurological prognostication (≥72 h) after treatment with targeted temperature management. Little is known about clinicians' experiences of early withdrawal of life support decisions in patients with OHCA., Objectives: To explore clinicians' experiences and perceptions of early withdrawal of life support decisions and barriers to guideline-concordant neurological prognostication in comatose survivors of OHCA treated with targeted temperature management., Methods: We conducted qualitative interviews with intensive care unit (ICU) physicians and nurses following withdrawal of life support in comatose patients with OHCA treated with targeted temperature management. The study was carried out across 18 academic and community hospitals participating in a multicenter, stepped-wedge, cluster-randomized controlled trial designed to improve quality-of-care processes for patients after OHCA in Ontario, Canada. We used a focused thematic analysis to capture barriers to guideline-concordant neurological prognostication and used these barriers to identify potentially modifiable issues., Measurements and Main Results: The core thematic finding was a high emotional burden of ICU family-team communication in which strong feelings inhibited information transfer and delayed decision making following OHCA. Four subthemes describing sources of communication strain were identified: (1) requests from family members to provide early outcome predictions, (2) incomplete family comprehension of critical care, (3) family requests for early withdrawal of life support based on their understanding of patients' preferences and values, and (4) family-team communication gaps related to prognostic uncertainty. Participants worried that gaps in timely and clear prognostic information contributed to surrogates' perceptions of a poor outcome and to inappropriately early decisions to withdraw life support., Conclusions: Family-team communication difficulties may be an underestimated factor leading to early withdrawal of life support in ICUs for individuals who initially survive OHCA.

Background: Oral care plays a clear and important role in the prevention of ventilator-associated pneumonia. However, few studies have explored the actual work of oral care by nurses in the intensive care unit., Objective: To explore intensive care nurses' knowledge of and experiences with the delivery of oral care to reveal less visible aspects of this work., Methods: In an institutional ethnography, go-along and semistructured interview methods were used to explore the oral care practices and perspectives of 12 bedside nurses and 12 interprofessional (intensivist, allied health, and management) participants in an intensive care unit at a large urban teaching hospital in Ontario, Canada., Results: Nurses described how obstacles frequently inhibited the delivery of oral care. Technical barriers included oral crowding with tubes and aversive responses by patients, such as biting. Contextual impediments to oral care included time constraints, lack of training, and limited opportunities for interprofessional collaboration. A key discovery was the presence of an informal unit-based nursing curriculum, whereby nurses acquired strategies to overcome barriers to oral care. Although the nurses did extensive problem solving in providing oral care, the interprofessional participants had limited knowledge of how oral care was accomplished., Conclusion: These data suggest the complexity of performing oral care in intensive care is underestimated and perhaps undervalued. Future research is needed to address technical and contextual barriers to optimize current guideline expectations for the provision of regular and effective oral care., (©2016 American Association of Critical-Care Nurses.)

The omission of oral care is linked to increased nurse workload and may contribute to serious patient infection and growing healthcare costs. Therefore, ineffective oral care comprises a significant patient safety issue across healthcare settings internationally. As studies have demonstrated a positive relationship between Nurs Leadersh (Tor Ont) and improved patient outcomes, it is imperative that leaders seek effective approaches to facilitate contextual exploration of barriers and facilitators for resolution of oral care delivery problems. One approach to improved processes of oral care is the creative engagement of front-line clinicians in the problems they confront in everyday practice. By drawing upon the role and process of facilitation, we outline two projects, located in Australia and Canada, that engaged front-line nurses, health leaders, and researchers as partners to identify a path to improved oral care delivery. In this paper, we summarize key learnings for nursing leaders about strategies to facilitate delivery of fundamental oral care. We found that facilitation, contextual knowledge and academic-clinician partnerships were essential to the detection and evaluation of oral care delivery problems and the identification of priorities for practice improvement. As collaboration is imperative for sustainable innovation, we summarize strategies of effective leadership for improving oral care delivery., (Copyright © 2016 Longwoods Publishing.)

Exercise-based cardiac rehabilitation (CR) programs help patients with coronary heart disease (CHD) reduce their risk of recurrent cardiac illness, disability, and death. However, men with CHD and Type 2 diabetes mellitus (T2DM) demonstrate lower attendance and completion of CR despite having a poor prognosis. Drawing on gender and masculinity theory, we report on a qualitative study of 16 Canadian diabetic men recently enrolled in CR. Major findings reflect two discursive positions men assumed to regain a sense of competency lost in illness: (a) working with the experts, or (b) rejection of biomedical knowledge. These positions underscore the varied and sometimes contradictory responses of seriously ill men to health guidance. Findings emphasize the priority given to the rehabilitation of a positive masculine identity. The analysis argues that gender, age, and employment status are powerful mechanisms of variable CR participation., (© The Author(s) 2015.)

Background: Audit and feedback is integral to performance improvement and behaviour change in the intensive care unit (ICU). However, there remain large gaps in our understanding of the social experience of audit and feedback and the mechanisms whereby it can be optimised as a quality improvement strategy in the ICU setting., Methods: We conducted a modified grounded theory qualitative study. Seventy-two clinicians from five academic and five community ICUs in Ontario, Canada, were interviewed. Team members reviewed interview transcripts independently. Data analysis used constant comparative methods., Results: Clinicians interviewed experienced audit and feedback as fragmented and variable in its effectiveness. Moreover, clinicians felt disconnected from the process. The audit process was perceived as being insufficiently transparent. Feedback was often untimely, incomplete and not actionable. Specific groups such as respiratory therapists and night-shift clinicians felt marginalised. Suggestions for improvement included improving information sharing about the rationale for change and the audit process, tools and metrics; implementing peer-to-peer quality discussions to avoid a top-down approach (eg, incorporating feedback into discussions at daily rounds); providing effective feedback which contains specific, transparent and actionable information; delivering timely feedback (ie, balancing feedback proximate to events with trends over time) and increasing engagement by senior management., Conclusions: ICU clinicians experience audit and feedback as fragmented communication with feedback being especially problematic. Attention to improving communication, integration of the process into daily clinical activities and making feedback timely, specific and actionable may increase the effectiveness of audit and feedback to affect desired change., (Published by the BMJ Publishing Group Limited.

In contrast to acute or chronic dosing experiments with a single chemical in animals, man is exposed to thousands of chemicals during a lifetime. Each of these may act alone, additively, synergistically or antagonistically in terms of biological effects, but most current risk assessment procedures fail to recognize such interactions. In carcinogenesis, a mutational process that is thought to occur through DNA damage by endogenous and/or exogenous agents, a wide variety of host factors is involved in disease outcome. These include absorption of chemicals, their distribution, metabolism and excretion. In addition, once metabolic activation has occurred, there is an array of protective mechanisms that cells have evolved to maintain DNA integrity, such as DNA repair, genetic redundancy and programmed cell death. One approach to risk assessment is to regard all DNA-damaging events as potentially leading to cancer and to measure DNA damage as the biologically relevant endpoint. The main method, if not the only method, presently available to assay a wide range of DNA adducts is 32P-postlabelling. This method has high sensitivity (limit of detection > 1 adduct per 10(10) nucleotides) and is capable of visualizing many different DNA adducts in a single analysis. Postlabelling is best suited for detecting hydrophobic adducts--low molecular weight adducts usually need a preliminary separation procedure prior to being postlabelled. This chromatographic procedure has been used to study DNA samples from human tissues of cigarette smokers, occupationally exposed groups and individuals living in polluted environments. Correlations have been found between the severity of exposure and the level of DNA adducts detected for human samples. However, most studies are single-time point studies, whereas for risk assessment purposes it may be better to use more quantitative and representative measures of long-term exposure, for example the number of adducts formed per annum. This article reviews methods of DNA adduct measurement, with particular reference to the 32P-postlabelling technique, which has been used to determine DNA adduct levels in populations exposed to complex mixtures.
