Community Group-Based Physical Activity Programs for Immigrant Older Adults: A Systematic Realist Review.

Physical activity program interventions often lack sensitivity to the needs of older immigrant adults. The objective of this systematic realist review is to explain how, why, for whom, and under which circumstances community group-based physical activity programs work for immigrant older adults. The initial program theory was developed using prior research, team expertise, social cognitive theory, and knowledge user consultations. The program theory was tested and refined via a systematic review of the literature. Database searches were conducted in MEDLINE, EMBASE, CINAHL, Scopus, Cochrane Library, Sports Medicine and Education Index, and SPORTDiscus. A total of 22 sources of evidence met inclusion criteria and included intervention studies, systematic reviews, and a discussion paper. Intervention studies were appraised using the Mixed Methods Appraisal Tool. The final program theory constituted eight context-mechanism-outcome configurations that highlight the importance of facilitator characteristics, access to safe spaces, group dynamics, and social support. A limitation was the small number and variable quality of included evidence. Physical activity programs that target immigrant older adults must strengthen physical and psychological safety and maximize opportunities for role modeling and socialization. This research was supported by the Alberta Health Services Seniors Health Strategic Clinical Network and is registered in PROSPERO (ID#258179).

Evidence for the use of cannabis-based medicines in osteoarthritis: a scoping review.

The purpose of this study was to conduct a scoping review to describe the evidence on the efficacy and safety of using cannabis-based medicines for osteoarthritis. The review was conducted following the framework proposed by Arksey and O'Malley and reported following PRISMA extension for scoping reviews guidelines. We conducted a comprehensive search across various databases including MEDLINE, Embase, Cochrane Library, CINAHL, Scopus, and Proquest, spanning from inception of each database to March 2023. We retrieved 2533 citations, and after deduplication, title and abstract screening, and full-text screening, 10 articles were included for analysis. These studies were composed of randomized-controlled trials (n = 4/10), cross-sectional surveys (n = 3/10), case studies (n = 2/10), and a cohort study (n = 1/10). Evidence for using cannabis-based medicines was mixed, with just 60% (n = 6/10) of included studies reporting statistically significant improvements in pain. Studies with larger samples sizes and longer durations of exposure did not find significant benefits for pain. The few adverse effects reported were generally mild and affected a minority of participants. Several studies also discovered that cannabis-based medicines were associated with a reduction in opioid use. Currently available data on the use of cannabis-based medicines in osteoarthritis is insufficient to make recommendations. Future research should address concerns regarding small sample sizes and short treatment durations to provide a more robust evidence base. Key Points • Current evidence remains mixed; studies that found a positive benefit with using cannabis-based medicines had limitations with small sample sizes and short durations of exposure • The use of cannabis-based medicines in osteoarthritis appears to be generally well tolerated, adverse effects are mild and experienced by a minority of participants • Cannabis-based medicines may decrease the use of opioids in patients with osteoarthritis • Future research should address the gaps in long-term efficacy and safety data.

Shoulder specific exercise therapy is effective in reducing chronic shoulder pain: A network meta-analysis.

BACKGROUND: Exercise therapy (ET) is frequently an early treatment of choice when managing shoulder pain, yet evidence on its efficacy to expedite recovery is inconsistent. Moreover, the value of adding adjunct therapies (i.e. injections, manual therapy, electrotherapy) to ET is currently unclear. This study combined both direct and indirect evidence across studies on the effectiveness of ET with/without adjunct therapies compared to usual medical care for adults with chronic shoulder pain. METHODS AND FINDINGS: Using a network meta-analysis, randomized control trials comparing ET along with adjunct therapies were identified in MEDLINE, Embase, CINAHL, Sportdiscus, CENTRAL, Conference Proceedings Citation Index-Science, clinicaltrials.gov, and association websites. Outcomes included pain, range of motion (ROM), and health-related quality of life (HRQL) measures in adult patients with chronic shoulder pain. Data analysis used a Frequentist hierarchical model. CINeMA tool assessed the confidence in the results and Cochrane Risk of Bias tool assessed quality of studies. 54 studies primarily from Europe (40.38%) included 3,893 participants who were followed up to 52 weeks. Shoulder-specific ET (Mean difference (MD) = -2.1; 95% confidence interval (CI) = -3.5 to -0.7) or in combination with electro-physical agents (MD = -2.5; 95% CI = -4.2 to -0.7), injections (MD = -2.4; 95% CI = -3.9 to-1.04) or manual therapy (MD = -2.3; 95% CI = -3.7 to -0.8) decreased pain compared to usual medical care. Trends with ROM and HRQL scores were seen; however, only Manual Therapy (MD = -12.7 and 95% CI = -24.4 to -1.0) achieved meaningfully important changes. Sensitivity analysis excluding studies with high risk of bias showed similar results, with exception of injections that did not reach significance (MD = -1.3; 95% CI = -4.3 to 1.7). CONCLUSION(S): Shoulder-specific ET provided pain relief up to 52 weeks. Adjunct therapies to shoulder-specific ET added little value in reducing pain. The quality of evidence varied between moderate and very low.

OMERACT Core outcome measurement set for shared decision making in rheumatic and musculoskeletal conditions: a scoping review to identify candidate instruments.

OBJECTIVES: Shared decision making (SDM) is a central tenet in rheumatic and musculoskeletal care. The lack of standardization regarding SDM instruments and outcomes in clinical trials threatens the comparative effectiveness of interventions. The Outcome Measures in Rheumatology (OMERACT) SDM Working Group is developing a Core Outcome Set for trials of SDM interventions in rheumatology and musculoskeletal health. The working group reached consensus on a Core Outcome Domain Set in 2020. The next step is to develop a Core Outcome Measurement Set through the OMERACT Filter 2.2. METHODS: We conducted a scoping review (PRISMA-ScR) to identify candidate instruments for the OMERACT Filter 2.2 We systematically reviewed five databases (Ovid MEDLINE®, Embase, Cochrane Library, CINAHL and Web of Science). An information specialist designed search strategies to identify all measurement instruments used in SDM studies in adults or children living with rheumatic or musculoskeletal diseases or their important others. Paired reviewers independently screened titles, abstracts, and full text articles. We extracted characteristics of all candidate instruments (e.g., measured construct, measurement properties). We classified candidate instruments and summarized evidence gaps with an adapted version of the Summary of Measurement Properties (SOMP) table. RESULTS: We found 14,464 citations, read 239 full text articles, and included 99 eligible studies. We identified 220 potential candidate instruments. The five most used measurement instruments were the Decisional Conflict Scale (traditional and low literacy versions) (n=38), the Hip/Knee-Decision Quality Instrument (n=20), the Decision Regret Scale (n=9), the Preparation for Decision Making Scale (n=8), and the CollaboRATE (n=8). Only 44 candidate instruments (20%) had any measurement properties reported by the included studies. Of these instruments, only 57% matched with at least one of the 7-criteria adapted SOMP table. CONCLUSION: We identified 220 candidate instruments used in the SDM literature amongst people with rheumatic and musculoskeletal diseases. Our classification of instruments showed evidence gaps and inconsistent reporting of measurement properties. The next steps for the OMERACT SDM Working Group are to match candidate instruments with Core Domains, assess feasibility and review validation studies of measurement instruments in rheumatic diseases or other conditions. Development and validation of new instruments may be required for some Core Domains.

An outbreak of Salmonella Typhimurium associated with the consumption of raw liver at an Eid al-Adha celebration in Wales (UK), July 2021.

In July 2021, Public Health Wales received two notifications of salmonella gastroenteritis. Both cases has attended the same barbecue to celebrate Eid al-Adha, two days earlier. Additional cases attending the same barbecue were found and an outbreak investigation was initiated. The barbecue was attended by a North African community's social network. On same day, smaller lunches were held in three homes in the social network. Many people attended both a lunch and the barbecue. Cases were defined as someone with an epidemiological link to the barbecue and/or lunches with diarrhoea and/or vomiting with date of onset following these events. We undertook a cohort study of 36 people attending the barbecue and/or lunch, and a nested case-control study using Firth logistic regression. A communication campaign, sensitive towards different cultural practices, was developed in collaboration with the affected community. Consumption of a traditional raw liver dish, 'marrara', at the barbecue was the likely vehicle for infection (Firth logistic regression, aOR: 49.99, 95%CI 1.71-1461.54, p = 0.02). Meat and offal came from two local butchers (same supplier) and samples yielded identical whole genome sequences as cases. Future outbreak investigations should be relevant to the community affected by considering dishes beyond those found in routine questionnaires.

Perceptions of Cannabis Use: A Qualitative Descriptive Study of Rheumatology Patients.

INTRODUCTION/OBJECTIVES: Some rheumatology patients use or contemplate using cannabis, however, may not be transparent about use with their providers. The objective of this qualitative descriptive study was to describe beliefs, perceptions, and learning needs of adults with rheumatic conditions regarding the use of cannabis products. METHODS: Purposive sampling was conducted through a rheumatology clinic and sought participants who were using or thinking about using cannabis. Two online focus groups based on cannabis use patterns (non-users and users) were conducted separately. Interviews were audio recorded and transcribed. Three research team members read the transcripts independently to identify initial codes and themes. Data saturation was reached with the interviews. RESULTS: We recruited 12 participants between 52 and 85 years old. The first theme was pain and desperation. Stigma was the second theme with a perception of physician opposition to cannabis, and the reluctance of many participants to discuss cannabis use with physicians. The final theme was a need for information and a general lack of trustworthy and credible sources. Users were willing to try cannabis even if they still had questions. CONCLUSION: Rheumatology patients are open to using cannabis due to the burden and suffering associated with pain. They remain silent on the topic, however, because of stigma and lack of engagement from health care professionals, particularly physicians. Patients voiced a strong need for information regarding cannabis and want healthcare providers to initiate discussion. These findings are clinically relevant to the management of rheumatic conditions and the promotion of therapeutic relationships.

Impact of the COVID-19 pandemic on Muslim older immigrants in Edmonton, Alberta: A community-based participatory research project with a local mosque.

OBJECTIVE: Older Muslim immigrants experience multiple vulnerabilities living in Canada. This study explores the experiences of Muslim older adults during the COVID-19 pandemic to identify ways to build community resilience as part of a community-based participatory research partnership with a mosque in Edmonton, Alberta. METHODS: Using a mixed-methods approach, check-in surveys (n = 88) followed by semi-structured interviews (n = 16) were conducted to assess the impact of COVID-19 on older adults from the mosque congregation. Quantitative findings were reported through descriptive statistics, and thematic analysis guided the identification of key findings from the interviews using the socio-ecological model. RESULTS: Three major themes were identified in consultation with a Muslim community advisory committee: (a) triple jeopardy leading to loneliness, (b) decreased access to resources for connectivity, and (c) organizational struggles to provide support during the pandemic. The findings from the survey and interviews highlight various supports that were missing during the pandemic for this population. CONCLUSION: The COVID-19 pandemic exacerbated the challenges associated with aging in the Muslim population and contributed to further marginalization, with mosques being sites of support during times of crises. Policymakers and service providers must explore ways of engaging mosque-based support systems in meeting the needs of older Muslim adults during pandemics.

RéSUMé: OBJECTIF: Les immigrants musulmans âgés vivant au Canada sont confrontés à des vulnérabilités multiples. Cette étude explore les expériences des personnes âgées musulmanes durant la pandémie de COVID-19 afin d'identifier des moyens pour renforcer la résilience communautaire dans le cadre d'un partenariat de recherche participative communautaire (CBPR) avec une mosquée à Edmonton, en Alberta. MéTHODES: À l'aide d'une approche à méthodes mixtes, des enquêtes de contrôle (n = 88) suivies d'entretiens semi-dirigés (n = 16) ont été menés pour évaluer l'impact du COVID-19 sur les personnes âgées de la congrégation de la mosquée. Les résultats quantitatifs ont été rapportés au moyen de statistiques descriptives, tandis que l'analyse thématique a guidé l'identification des principaux résultats des entretiens à l'aide du modèle socio-écologique. RéSULTATS: Trois thèmes majeurs ont été identifiés en concertation avec un comité consultatif de la communauté musulmane : a) triple péril menant à la solitude, b) accès réduit aux ressources pour la connectivité, et c) luttes organisationnelles pour fournir un soutien pendant la pandémie. Les résultats de l'enquête et des entretiens mettent en évidence le manque d'aides diverses à cette population durant la pandémie. CONCLUSION: La pandémie de COVID-19 a exacerbé les défis associés au vieillissement de cette population et a contribué à une marginalisation supplémentaire, les mosquées étant des sites de soutien en temps de crise. Les décideurs politiques et les prestataires de services doivent explorer les moyens d'engager les systèmes d'aide basés dans les mosquées pour répondre aux besoins des adultes musulmans âgés pendant les pandémies.

Measurement of obesity in primary care practice: chronic conditions matter.

Primary care providers can deliver tailored advice and support to patients who are overweight or have obesity. The 2020 Canadian Adult Obesity Practice Guideline for primary care providers recommended that patients' waist circumference (WC) be measured if their height and weight place them in the overweight or Class I obesity category. The guideline does not recommend how often providers should measure WC nor describe how often this is measured in current practice. We reviewed electronic medical records (EMRs) of 707,819 Canadian adult patients aged 40 and older. Among them, 48.7% had 1 or more body mass index (BMI) recorded; 11.5% had at least 1 waist measurement recorded. Of those with a BMI classified as overweight or having Class I obesity, 23.7% had at least 1 WC measurement recorded, which differed by chronic disease. WC was documented in more patients who had diabetes mellitus (36.8%) than hypertension (26.1%), or osteoarthritis (24.3%). This difference may be reflective of more specific advice in diabetes guidelines. To our knowledge, this is the first study to describe documentation of WC measurement for patients who are overweight or have Class I obesity in Canadian primary care EMRs across obesity-related conditions.

Urinary urgency acts as a source of divided attention leading to changes in gait in older adults with overactive bladder.

AIMS: There is a well-recognised but unexplained association between lower urinary tract symptoms including urgency and urgency incontinence and falls in older people. It has been hypothesised that urinary urgency acts as a source of divided attention, leading to gait changes which increase falls risk. This study aimed to assess whether urinary urgency acts as a source of divided attention in older adults with overactive bladder (OAB). METHODS: 27 community-dwelling adults aged 65 years and over with a clinical diagnosis of OAB underwent 3-Dimensional Instrumented Gait Analysis under three conditions; bladder empty, when experiencing urgency, and when being distracted by the n-back test. Temporal-spatial gait and kinematic gait data were compared between each condition using repeated measures ANOVA. RESULTS: Gait velocity decreased from 1.1ms-1 in the bladder empty condition to 1.0ms-1 with urgency and 0.9ms-1 with distraction (p = 0.008 and p<0.001 respectively). Stride length also decreased, from 1.2m to 1.1m with urgency and 1.0m with distraction (p<0.001 for both). The presence of detrusor overactivity did not influence these results (p = 0.77). CONCLUSIONS: In older adults with OAB, urinary urgency induced similar changes in gait to those caused by a distracting task. These gait changes are associated with increased fall risk. This may be part of the explanation for the association between falls and lower urinary tract symptoms in older people. Future research should examine the effect of pharmacological treatment of OAB on gait and on the effect of dual-task training on gait when experiencing urgency.

Endorsement of the domains of knee and hip osteoarthritis (OA) flare: A report from the OMERACT 2020 inaugural virtual consensus vote from the flares in OA working group.

OBJECTIVE: Towards developing an instrument to measure knee and hip osteoarthritis (KHOA) flare, the Outcome Measures in Rheumatology (OMERACT) Flares in OA Working Group first sought to identify and define relevant domains of flare in KHOA. METHODS: Guided by OMERACT Filter 2.1, candidate domains were identified from data generated in interviews, in English or French, with persons with KHOA and health professionals (HPs) who treat OA. The first and second rounds of an online Delphi process with patients and HPs, including researchers, selected relevant domains. The third round provided agreement on the selected domains and their definitions. At the virtual OMERACT 2020 workshop, the proposed domains and their definitions were discussed in facilitated breakout groups with patients and HPs. Participants then voted, with consensus set at ≥70%. RESULTS: Qualitative interviews characterizing OA flare were completed with 29 persons with KHOA and 16 HPs. Content was analyzed and grouped into nine clusters. These candidate domains were included in two Delphi rounds, completed by 91 patients and 165 HPs then 50 patients and 116 HPs, per round, respectively. This resulted in selecting five relevant domains. A final Delphi round, completed by 38 patients and 89 HPs, provided agreement on these domains and their definitions. The OMERACT virtual vote included 27 patients and 106 HPs. The domains and their definitions were endorsed with ≥98% agreement. Domains include: Pain, Swelling, Stiffness, Psychological aspects, and Impact of symptoms, all defined "during flare". CONCLUSION: Using OMERACT methodology, we have developed five domains of KHOA flare that were highly endorsed by patients and HPs.

The Role of Information and Communication Technology (ICT) for Older Adults' Decision-Making Related to Health, and Health and Social Care Services in Daily Life-A Scoping Review.

Information and communication technology (ICT) can potentially support older adults in making decisions and increase their involvement in decision-making processes. Although the range of technical products has expanded in various areas of society, knowledge is lacking on the influence that ICT has on older adults' decision-making in everyday situations. Based on the literature, we aimed to provide an overview of the role of ICT in home-dwelling older adults' decision-making in relation to health, and health and social care services. A scoping review of articles published between 2010 and 2020 was undertaken by searching five electronic databases. Finally, 12 articles using qualitative, quantitative, and mixed-method designs were included. The articles were published in journals representing biology and medicine, nursing, informatics, and computer science. A majority of the articles were published in the last five years, and most articles came from European countries. The results are presented in three categories: (i) form and function of ICT for decision-making, (ii) perceived value and effect of ICT for decision-making, and (iii) factors influencing ICT use for decision-making. According to our findings, ICT for decision-making in relation to health, and health and social care services was more implicitly described than explicitly described, and we conclude that more research on this topic is needed. Future research should engage older adults and health professionals in developing technology based on their needs. Further, factors that influence older adults' use of ICT should be evaluated to ensure that it is successfully integrated into their daily lives.

Features of the social and built environment that contribute to the well-being of people with dementia who live at home: A scoping review.

This scoping review summarizes findings from 23 qualitative articles on how social and built environments contribute to the well-being of people with dementia who live at home. Through thematic analysis, two themes were identified: i) connection to society and supportive relationships and ii) interaction with natural environments and public space. Features of the social and built environment contribute to well-being both positively and negatively. Future research should explore how these features intersect in an urban-rural context as a basis to inform the development of dementia-friendly initiatives. Moreover, involving people with dementia in the design of features of built environments, such as infrastructure, will result in more inclusive communities.

A Qualitative Exploration of Immigrant Muslim Older Adults' Experiences and Perceptions of Physical Activity.

Physical activity is essential for healthy aging; however, there has been little exploration of physical activity in Muslim older immigrants in Canada. Over one million Canadians identify as Muslim, the majority is first-generation immigrants, with increasing cohorts entering older age. A community-based participatory research project on healthy aging was conducted with 68 older adults and community members from South Asian, Arab, and African Muslim ethnocultural communities in a Canadian urban center. A combination of individual interviews and focus groups discussions were completed, followed by thematic analysis of data. Participating community groups emphasized the importance of physical activity in older age and prioritized the need for physical activity programs. The four themes highlight Muslim older immigrants' perspectives on physical activity in Canada: (a) values and approaches to staying active; (b) health factors: pain and health limitations; (c) social factors: culture, religion, and belonging; and (d) environmental factors: safety and accessibility.

Improving a Web-Based Tool to Support Older Adults to Stay Independent at Home: Qualitative Study.

BACKGROUND: Older adults desire to stay independent at home for as long as possible. We developed an interactive website to inform older adults and caregivers about ways to achieve this. OBJECTIVE: This study aimed to perform an in-depth exploration among potential end users about how to improve the interactive website to better inform older adults and caregivers about ways to stay independent at home. METHODS: To complement the results of a quantitative survey on the usability and acceptability of the website before implementation, we conducted a qualitative descriptive study. Using multiple recruitment strategies, we recruited a purposeful sample of older adults (aged ≥65 years) and caregivers of older adults struggling to stay independent at home. We conducted face-to-face or telephonic interviews in either English or French. In addition, we collected sociodemographic characteristics, other characteristics of participants (eg, health, digital profile, and perception of retirement homes), and experiences with using the website (factors facilitating the use of the website, barriers to its use, and suggestions for improvement). Interviews were audio recorded, transcribed verbatim, and thematically analyzed by two researchers. RESULTS: We recruited 15 participants, including 5 older adults (mean age 75 years, SD 6) and 10 caregivers (mean age 57 years, SD 14). The mean interview time was 32 min (SD 14). Most older adults had either mobility or health problems or both, and many of them were receiving home care services (eg, blood pressure measurement and body care). Overall, participants found the website easy to navigate using a computer, reassuring, and useful for obtaining information. Barriers were related to navigation (eg, difficult to navigate with a cellphone), relevance (eg, no specific section for caregivers), realism (eg, some resources presented are not state funded), understandability (eg, the actors' accents were difficult to understand), and accessibility (eg, not adapted for low digital literacy). Suggestions for improvement included a needs assessment section to direct users to the support appropriate to their needs, addition of information about moving into residential care, a section for caregivers, distinction between state-provided and private support services, simpler language, expansion of content to be relevant to all of Canada, and video subtitles for the hearing impaired. CONCLUSIONS: Users provided a wealth of information about the needs of older adults who were facing a loss of autonomy and about what such a website could usefully provide. The request for less generic and more personalized information reflects the wide range of needs that electronic health innovations, such as our interactive website, need to address. After integrating the changes suggested, the new website-Support for Older Adults to Stay Independent at Home (SUSTAIN)-will be implemented and made available to better assist older adults and caregivers in staying independent at home.

Can clinical assessment differentiate partial thickness rotator cuff tears from full thickness rotator cuff tears? A secondary analysis.

Purpose: Shoulder pain causes significant disability, with rotator cuff disease as a common diagnosis. Differentially diagnosing partial tears of the rotator cuff tendons is difficult despite use of imaging and clinical examination. Our objective was to determine if a clinical assessment framework could discriminate between patients with partial and full thickness tears.Materials and Methods: Pre-operative baseline data from two randomized controlled trials of 452 adult patients awaiting rotator cuff repair were analyzed in this secondary analysis. Nineteen items from a pre-defined clinical assessment framework were investigated for association with the outcome of surgically confirmed partial or full thickness tear. Logistic regression tested independent associations and multivariable models were developed to create the most parsimonious model.Results: Thirty-two participants (7%) had partial thickness tears. Constant Power Score was the sole item associated with partial thickness tears (OR 1.07, 95% CI 1.02-1.12). Traumatic mechanism of injury trended toward significance (OR 2.17, 95% CI 1.06-4.48).Conclusions: Greater abduction strength (i.e., Constant Power Score) was associated with partial thickness tears. Other clinical assessment items did not differentiate between partial and full tears. Our results add to the growing body of research showing most clinical findings are not associated with a diagnosis in rotator cuff disease.Implications for RehabilitationGreater shoulder abduction strength (as measured with the Constant Power Score) was associated with partial thickness rotator cuff tears.Most findings within our clinical assessment framework did not distinguish between partial thickness and full thickness rotator cuff tears and thus, did not contribute to a differential pathoanatomical diagnosis.Since structural integrity of the rotator cuff and patient presentation show poor association, and rehabilitation intervention is often impairment-based, pathoanatomical diagnosis may not adequately direct non-surgical treatment. Including movement-based diagnoses or treatment classification systems in evaluation of rotator cuff disease may improve selection of appropriate conservative treatment.

Toileting Disability in Older People Residing in Long-term Care or Assisted Living Facilities: A Scoping Review of the Literature.

For purposes of this review, we defined toileting disability as a result of practices, procedures, or conditions that result in an individual requiring assistance using the bathroom. This scoping review synthesizes existing knowledge of extrinsic and/or intrinsic factors that might lead to or be associated with toileting disability and identified knowledge gaps related to toileting disability in older adults residing in long-term care or assisted living facilities. A search of 9 electronic databases and the gray literature identified 3613 articles. After exclusions and screening of the full text of 71 articles, 7 remaining eligible articles mapped research activity and identified knowledge gaps in this area. Only 1 study used toileting disability as the primary outcome; it was present in 15% of older adults without dementia living in long term-care facilities (a subgroup that comprised 34% of all residents). The other 6 articles examined factors and treatment of overall activities of daily living (ADL) performance as their primary outcome; in these, toileting disability was added to other difficulties, yielding a summary ADL outcome score. No study reported the incidence, distribution, or factors that affect toileting disability in long-term care; findings of this scoping review suggest a rich research agenda for future investigation.

Commonalities and differences in the implementation of models of care for arthritis: key informant interviews from Canada.

BACKGROUND: Timely access to effective treatments for arthritis is a priority at national, provincial and regional levels in Canada due to population aging coupled with limited health human resources. Models of care for arthritis are being implemented across the country but mainly in local contexts, not from an evidence-informed policy or framework. The purpose of this study is to examine existing models of care for arthritis in Canada at the local level in order to identify commonalities and differences in their implementation that could point to important considerations for health policy and service delivery. METHODS: Semi-structured key informant interviews were conducted with 70 program managers and/or care providers in three Canadian provinces identified through purposive and snowball sampling followed by more detailed examination of 6 models of care (two per province). Interviews were transcribed verbatim and analyzed thematically using a qualitative descriptive approach. RESULTS: Two broad models of care were identified for Total Joint Replacement and Inflammatory Arthritis. Commonalities included lack of complete and appropriate referrals from primary care physicians and lack of health human resources to meet local demands. Strategies included standardized referrals and centralized intake and triage using non-specialist health care professionals. Differences included the nature of the care and follow-up, the role of the specialist, and location of service delivery. CONCLUSIONS: Current models of care are mainly focused on Total Joint Replacement and Inflammatory Arthritis. Given the increasing prevalence of arthritis and that published data report only a small proportion of current service delivery is specialist care; provision of timely, appropriate care requires development, implementation and evaluation of models of care across the continuum of care.

Percutaneous vertebroplasty for osteoporotic vertebral compression fracture.

BACKGROUND: Percutaneous vertebroplasty is widely used to treat acute and subacute painful osteoporotic vertebral fractures although recent placebo-controlled trials have questioned its value. OBJECTIVES: To synthesise the available evidence regarding the benefits and harms of vertebroplasty for treatment of osteoporotic vertebral fractures. SEARCH METHODS: We searched CENTRAL, MEDLINE and EMBASE up to November 2014. We also reviewed reference lists of review articles, trials and trial registries to identify any other potentially relevant trials. SELECTION CRITERIA: We included randomised and quasi-randomised controlled trials (RCTs) including adults with painful osteoporotic vertebral fractures of any duration and comparing vertebroplasty with placebo (sham), usual care, or any other intervention. As it is least prone to bias, vertebroplasty compared with placebo was the primary comparison. Major outcomes were mean overall pain, disability, disease-specific and overall health-related quality of life, patient-reported treatment success, new symptomatic vertebral fractures and number of other serious adverse events. DATA COLLECTION AND ANALYSIS: At least two review authors independently selected trials for inclusion, extracted data, performed 'Risk of bias' assessment and assessed the quality of the body of evidence for the main outcomes using GRADE. MAIN RESULTS: Eleven RCTs and one quasi-RCT conducted in various countries were included. Two trials compared vertebroplasty with placebo (209 randomised participants), six compared vertebroplasty with usual care (566 randomised participants) and four compared vertebroplasty with kyphoplasty (545 randomised participants). Trial size varied from 34 to 404 participants, most participants were female, mean age ranged between 63.3 and 80 years, and mean symptom duration varied from a week to more than six months.Both placebo-controlled trials were judged to be at low overall risk of bias while other included trials were generally considered to be at high risk of bias across a range of criteria, most seriously due to lack of participant and study personnel blinding.Compared with placebo, there was moderate quality evidence based upon two trials that vertebroplasty provides no demonstrable benefits with respect to pain, disability, disease-specific or overall quality of life or treatment success. At one month, mean pain (on a scale 0 to 10, higher scores indicate more pain) was 5 points with placebo and 0.7 points better (1.5 better to 0.15 worse) with vertebroplasty, an absolute pain reduction of 7% (15% better to 1.5% worse) and relative reduction of 10% (21% better to 2% worse) (two trials, 201 participants). At one month, mean disability measured by the Roland Morris Disability Questionnaire (scale range 0 to 23, higher scores indicate worse disability) was 13.6 points in the placebo group and 1.1 points better (2.9 better to 0.8 worse) in the vertebroplasty group, absolute improvement in disability 4.8% (12.8% better to 3.3% worse), relative change 6.3% better (17.0% better to 4.4% worse) (two trials, 201 participants).At one month, disease-specific quality of life measured by the QUALEFFO (scale 0 to 100, higher scores indicating worse quality of life) was 2.4 points in the placebo group and 0.40 points worse (4.58 better to 5.38 worse) in the vertebroplasty group, absolute change: 0.4% worse (5% worse to 5% better), relative change 0.7% worse (9% worse to 8% better (based upon one trial, 73 participants). At one month overall quality of life measured by the EQ5D (0 = death to 1 = perfect health, higher scores indicate greater quality of life at one month was 0.27 points in the placebo group and 0.05 points better (0.01 worse to 0.11 better) in the vertebroplasty group, absolute improvement in quality of life 5% (1% worse to 11% better), relative change 18% better (4% worse to 39% better) (two trials, 201 participants). Based upon one trial (78 participants) at one month, 9/40 (or 225 per 1000) people perceived that treatment was successful in the placebo group compared with 12/38 (or 315 per 1000; range 150 to 664) in the vertebroplasty group, RR 1.40 (95% CI 0.67 to 2.95), absolute risk difference 9% more reported success (11% fewer to 29% more); relative change 40% more reported success (33% fewer to 195% more).Based upon moderate quality evidence from three trials (one placebo, two usual care, 281 participants) with up to 12 months follow-up, we are uncertain whether or not vertebroplasty increases the risk of new symptomatic vertebral fractures (28/143 observed in the vertebroplasty group compared with 19/138 in the control group; RR 1.47 (95% CI 0.39 to 5.50).Similary, based upon moderate quality evidence from two placebo-controlled trials (209 participants), we are uncertain about the exact risk of other adverse events (3/106 were observed in the vertebroplasty group compared with 3/103 in the placebo group; RR 1.01 (95% CI 0.21 to 4.85)). Notably, serious adverse events reported with vertebroplasty included osteomyelitis, cord compression, thecal sac injury and respiratory failure.Our subgroup analyses provided limited evidence that the effects did not differ according to duration of pain ≤ 6 weeks versus > 6 weeks. Including data from the six trials that compared vertebroplasty with usual care in a sensitivity analyses inconsistently altered the primary results, with all combined analyses displaying substantial to considerable heterogeneity. AUTHORS' CONCLUSIONS: Based upon moderate quality evidence, our review does not support a role for vertebroplasty for treating osteoporotic vertebral fractures in routine practice. We found no demonstrable clinically important benefits compared with a sham procedure and subgroup analyses indicated that results did not differ according to duration of pain ≤ 6 weeks versus > 6 weeks. Sensitivity analyses confirmed that open trials comparing vertebroplasty with usual care are likely to have overestimated any benefit of vertebroplasty. Correcting for these biases would likely drive any benefits observed with vertebroplasty towards the null, in keeping with findings from the placebo-controlled trials.Numerous serious adverse events have been observed following vertebroplasty. However due to the small number of events, we cannot be certain about whether or not vertebroplasty results in a clinically important increased risk of new symptomatic vertebral fractures and/or other serious adverse events. Patients should be informed about both the lack of high quality evidence supporting benefit of vertebroplasty and its potential for harm.

Healthcare providers' knowledge of disordered sleep, sleep assessment tools, and nonpharmacological sleep interventions for persons living with dementia: a national survey.

A large proportion of persons with dementia will also experience disordered sleep. Disordered sleep in dementia is a common reason for institutionalization and affects cognition, fall risk, agitation, self-care ability, and overall health and quality of life. This report presents findings of a survey of healthcare providers' awareness of sleep issues, assessment practices, and nonpharmacological sleep interventions for persons with dementia. There were 1846 participants, with the majority being from nursing and rehabilitation. One-third worked in long-term care settings and one-third in acute care. Few reported working in the community. Findings revealed that participants understated the incidence of sleep deficiencies in persons with dementia and generally lacked awareness of the relationship between disordered sleep and dementia. Their knowledge of sleep assessment tools was limited to caregiver reports, self-reports, and sleep diaries, with few using standardized tools or other assessment methods. The relationship between disordered sleep and comorbid conditions was not well understood. The three most common nonpharmacological sleep interventions participants identified using were a regular bedtime routine, increased daytime activity, and restricted caffeine. Awareness of other evidence-based interventions was low. These findings will guide evidence-informed research to develop and test more targeted and contextualized sleep and dementia knowledge translation strategies.

Chronic disease self-management for individuals with stroke, multiple sclerosis and spinal cord injury.

PURPOSE: The purpose of this study was to explore the experience of people with neurological conditions who take the chronic disease self-management (CDSM) programme. The CDSM programme is used to teach skills to manage chronic conditions, and prevent secondary conditions. Few studies have explored the use of the CDSM programme with people with neurological conditions, in spite of the long standing and sometimes unpredictable nature of those conditions. METHOD: This qualitative study explored the experience of people with stroke, multiple sclerosis (MS) and spinal cord injury (SCI) who participated in the CDSM programme. We completed individual interviews using a semi-structured interview guide with 22 individuals with stroke, MS and SCI. RESULTS: Five categories emerged from the interview discussions including: (1) pre-programme influences; (2) group; (3) factors affecting learning opportunities; (4) workshop content and (5) outcomes. CONCLUSIONS: The results of this study provide insights regarding the optimal way to present the CDSM programme to people with neurological conditions.
