Objective: Social and economic marginalizations have been associated with inferior health outcomes in Canada. Our objective was to describe the relationship between neighbourhood marginalization and COVID-19 outcomes among patients presenting to Canadian emergency departments (ED)., Methods: We conducted an observational study among consecutive COVID-19 patients recruited from 47 hospitals participating in the Canadian COVID-19 ED Rapid Response Network (CCEDRRN) between March 3, 2020, and July 24, 2022. We linked data with the Canadian Marginalization Index (CAN-Marg). We used multivariable, multi-level logistic regression models to understand the association between dimensions of neighbourhood marginalization, and severe COVID-19 and in-hospital mortality., Results: There were 55,588 eligible patients. Those from neighbourhoods with a higher proportion of recent immigrants (OR = 0.86 per unit increase [0.81, 0.92]), lower workforce participation (OR = 0.84 per unit increase [0.75, 0.94]), and more housing insecurity (OR = 0.81 per unit increase [0.77, 0.86]) were less likely to present to EDs with severe COVID-19. However, patients from materially marginalized neighbourhoods had increased odds of dying in hospital (OR = 1.19 per unit increase [95% CI 1.09, 1.30]) compared to patients from less materially marginalized neighbourhoods. Patients living in neighbourhoods with a higher proportion of recent immigrants (OR = 0.83 per unit increase [0.78, 0.91]) and lower participation in the workforce (OR = 0.77 per unit increase [0.66, 0.87]) experienced lower odds of dying., Conclusion: Despite no association with severe COVID-19 at ED presentation, the only marginalization domain associated with in-hospital mortality was material deprivation. Our findings present insights on ED-seeking behaviour, hospital access, and care that population studies could not., Competing Interests: Declarations.

Background: Emergency departments (EDs) worldwide are dealing with overcrowding, system fragmentation, and coordination problems, which impact patient wait times, staff job satisfaction, and patient outcomes. Inappropriate ED visits, particularly those for low acuity conditions, exacerbate these challenges. However, the motivations behind these visits are poorly understood, with limited data from the patient perspective. This study investigated patient-reported motives behind ED visits triaged as low acuity in Poznan, Poland, to propose health care system flow enhancements., Material and Methods: A cross-sectional survey and retrospective chart review were conducted in the ED of the Hipolit Cegielski Medical Center in Poznań, Poland, over three months in 2022-23. Patients who were triaged to have low acuity conditions were invited to participate in the survey. The data collected through the questionnaire included patient and ED visit characteristics. Additional information on the visits was extracted from the patient charts., Main Results: This study involved 293 patients who underwent low-acuity triage. Among them, 58 % were deemed to have conditions that could have been treated in primary care. Most of the patients (74 %) visited the ED of their own volition due to concerns about their health. Other reasons for ED attendance were challenges accessing primary care or a specialist clinic (11 %), system navigation problems (5 %), or a lack of trust in their primary care provider (2 %)., Conclusions: This study showed that of the patients surveyed, the majority had conditions that could have been treated outside of the ED setting. We recommend prioritizing education, particularly among younger adults, to increase awareness about nonurgent care options while improving health care policies., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Emergency medical systems in the world are mainly based on two main models: the Franco-German System (FGS) and the Anglo-American System (AAS). The characteristic feature of the FGS is the "Stay and Play" principle, while the AAS system is based on the "Scoop and Run" principle. The Polish model is a mix of those two systems mainly based on the work of paramedics. Their scope of operations and powers have changed over time. As a result of the advocacy undertaken by paramedics in Poland, legislation was drafted and became law in June 2023. The central changes include: the introduction of a paramedic register, the establishment of a professional self-government of paramedics, the expansion of professional competencies such as the ability to declare death, and new opportunities for professional development including speciality training or paid training leave. This article discusses the new law in the context of previous legislative solutions in the field of emergency medicine in Poland and in other European countries., Competing Interests: Declarations of competing interest None., (Copyright © 2024.

Objective: Unplanned return emergency department (ED) visits can reflect clinical deterioration or unmet need from the original visit. We determined the characteristics and outcomes of patients with COVID-19 who return to the ED for COVID-19-related revisits., Methods: This retrospective observational study used data for all adult patients visiting 47 Canadian EDs with COVID-19 between 1 March 2020 and 31 March 2022. Multivariable logistic regression assessed the characteristics associated with having a no return visit (SV=single visit group) versus at least one return visit (MV=return visit group) after being discharged alive at the first ED visit., Results: 39 809 patients with COVID-19 had 44 862 COVID-19-related ED visits: 35 468 patients (89%) had one visit (SV group) and 4341 (11%) returned to the ED (MV group) within 30 days (mean 2.2, SD=0.5 ED visit). 40% of SV patients and 16% of MV patients were admitted at their first visit, and 41% of MV patients not admitted at their first ED visit were admitted on their second visit. In the MV group, the median time to return was 4 days, 49% returned within 72 hours. In multivariable modelling, a repeat visit was associated with a variety of factors including older age (OR=1.25 per 10 years, 95% CI (1.22 to 1.28)), pregnancy (1.86 (1.46 to 2.36)) and presence of comorbidities (eg, 1.72 (1.40 to 2.10) for cancer, 2.01 (1.52 to 2.66) for obesity, 2.18 (1.42 to 3.36) for organ transplant), current/prior substance use, higher temperature or WHO severe disease (1.41 (1.29 to 1.54)). Return was less likely for females (0.82 (0.77 to 0.88)) and those boosted or fully vaccinated (0.48 (0.34 to 0.70))., Conclusions: Return ED visits by patients with COVID-19 within 30 days were common during the first two pandemic years and were associated with multiple factors, many of which reflect known risk for worse outcomes. Future studies should assess reasons for revisit and opportunities to improve ED care and reduce resource use., Trial Registration Number: ClinicalTrials.gov, NCT04702945., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Coronavirus disease 2019 (COVID-19) became a pandemic within a matter of months. Analysing the first year of the pandemic, data and surveillance gaps have subsequently surfaced. Yet, policy decisions and public trust in their country's strategies in combating COVID-19 rely on case numbers, death numbers and other unfamiliar metrics. There are many limitations on COVID-19 case counts internationally, which make cross-country comparisons of raw data and policy responses difficult., Purpose and Conclusions: This paper presents and describes steps in the testing and reporting process, with examples from a number of countries of barriers encountered in each step, all of which create an undercount of COVID-19 cases. This work raises factors to consider in COVID-19 data and provides recommendations to inform the current situation with COVID-19 as well as issues to be aware of in future pandemics., (© 2023.

Background: Testing is a foundational component of any COVID-19 management strategy; however, emerging evidence suggests that barriers and hesitancy to COVID-19 testing may affect uptake or participation and often these are multiple and intersecting factors that may vary across population groups. To this end, Health Canada's COVID-19 Testing and Screening Expert Advisory Panel commissioned this rapid review in January 2021 to explore the available evidence in this area. The aim of this rapid review was to identify barriers to COVID-19 testing and strategies used to mitigate these barriers., Methods: Searches (completed January 8, 2021) were conducted in MEDLINE, Scopus, medRxiv/bioRxiv, Cochrane and online grey literature sources to identify publications that described barriers and strategies related to COVID-19 testing., Results: From 1294 academic and 97 grey literature search results, 31 academic and 31 grey literature sources were included. Data were extracted from the relevant papers. The most cited barriers were cost of testing; low health literacy; low trust in the healthcare system; availability and accessibility of testing sites; and stigma and consequences of testing positive. Strategies to mitigate barriers to COVID-19 testing included: free testing; promoting awareness of importance to testing; presenting various testing options and types of testing centres (i.e., drive-thru, walk-up, home testing); providing transportation to testing centres; and offering support for self-isolation (e.g., salary support or housing)., Conclusion: Various barriers to COVID-19 testing and strategies for mitigating these barriers were identified. Further research to test the efficacy of these strategies is needed to better support testing for COVID-19 by addressing testing hesitancy as part of the broader COVID-19 public health response., (© 2022.

We identify the core services included in a community hub model of care to improve the understanding of this model for health leaders, decision-makers in community-based organizations, and primary healthcare clinicians. We searched Medline, PubMed, CINAHL, Scopus, Web of Science, and Google from 2000 to 2020 to synthesize original research on community hubs. Eighteen sources were assessed for quality and narratively synthesized (n = 18). Our analysis found 4 streams related to the service delivery in a community hub model of care: (1) Chronic disease management; (2) mental health and addictions; (3) family and reproductive health; and (4) seniors. The specific services within these streams were dependent upon the needs of the community, as a community hub model of care responds and adapts to evolving needs. Our findings inform the work of health leaders tasked with implementing system-level transformations towards community-informed models of care.

Background: Simple visualizations in health research data, such as scatter plots, heat maps, and bar charts, typically present relationships between 2 variables. Interactive visualization methods allow for multiple related facets such as numerous risk factors to be studied simultaneously, leading to data insights through exploring trends and patterns from complex big health care data. The technique presents a powerful tool that can be used in combination with statistical analysis for knowledge discovery, hypothesis generation and testing, and decision support., Objective: The primary objective of this scoping review is to describe and summarize the evidence of interactive visualization applications, methods, and tools being used in population health and health services research (HSR) and their subdomains in the last 15 years, from January 1, 2005, to March 30, 2019. Our secondary objective is to describe the use cases, metrics, frameworks used, settings, target audience, goals, and co-design of applications., Methods: We adapted standard scoping review guidelines with a peer-reviewed search strategy: 2 independent researchers at each stage of screening and abstraction, with a third independent researcher to arbitrate conflicts and validate findings. A comprehensive abstraction platform was built to capture the data from diverse bodies of literature, primarily from the computer science and health care sectors. After screening 11,310 articles, we present findings from 56 applications from interrelated areas of population health and HSR, as well as their subdomains such as epidemiologic surveillance, health resource planning, access, and use and costs among diverse clinical and demographic populations., Results: In this companion review to our earlier systematic synthesis of the literature on visual analytics applications, we present findings in 6 major themes of interactive visualization applications developed for 8 major problem categories. We found a wide application of interactive visualization methods, the major ones being epidemiologic surveillance for infectious disease, resource planning, health service monitoring and quality, and studying medication use patterns. The data sources included mostly secondary administrative and electronic medical record data. In addition, at least two-thirds of the applications involved participatory co-design approaches while introducing a distinct category, embedded research, within co-design initiatives. These applications were in response to an identified need for data-driven insights into knowledge generation and decision support. We further discuss the opportunities stemming from the use of interactive visualization methods in studying global health; inequities, including social determinants of health; and other related areas. We also allude to the challenges in the uptake of these methods., Conclusions: Visualization in health has strong historical roots, with an upward trend in the use of these methods in population health and HSR. Such applications are being fast used by academic and health care agencies for knowledge discovery, hypotheses generation, and decision support., International Registered Report Identifier (irrid): RR2-10.2196/14019., (©Jawad Chishtie, Iwona Anna Bielska, Aldo Barrera, Jean-Sebastien Marchand, Muhammad Imran, Syed Farhan Ali Tirmizi, Luke A Turcotte, Sarah Munce, John Shepherd, Arrani Senthinathan, Monica Cepoiu-Martin, Michael Irvine, Jessica Babineau, Sally Abudiab, Marko Bjelica, Christopher Collins, B Catharine Craven, Sara Guilcher, Tara Jeji, Parisa Naraei, Susan Jaglal.

Objective: We investigate whether older adults who were newly diagnosed with dementia (severity unspecified) and resided in an assisted living facility that offered a dementia care program had a lower rate of transition to a nursing home, compared to those who resided in an assisted living facility without such a program., Design: Population-based retrospective cohort study., Setting and Participants: Linked, person-level health system administrative data on older adults who were newly diagnosed with dementia and resided in an assisted living facility in Ontario, Canada, from 2014 to 2019 (n = 977)., Methods: Access to a dementia care program in an assisted living facility (n = 57) was examined. Multivariable Cox proportional hazards regression with robust standard errors clustered on the assisted living facility was used to model the time to transition to a nursing home from the new dementia diagnosis., Results: There were 11.8 transitions to a nursing home per 100 person-years among older adults who resided in an assisted living facility with a dementia care program, compared with 20.5 transitions to a nursing home per 100 person-years among older adults who resided in an assisted living facility without a dementia care program. After adjustment for relevant characteristics at baseline, older adults who resided in an assisted living facility with a dementia care program had a 40% lower rate of transition to a nursing home (hazard ratio 0.60, 95% confidence interval 0.44, 0.81), compared with those in an assisted living facility without such a program at any point during the follow-up period., Conclusions and Implications: The rate of transition to a nursing home was significantly lower among older adults who resided in an assisted living facility that offered a dementia care program. These findings support the expansion of dementia care programs in assisted living facilities., (Copyright © 2021 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Background: Many residents of assisted living facilities live with dementia, but little is known about the characteristics of assisted living facilities that provide specialized care for older adults who live with dementia. In this study, we identify the characteristics of assisted living facilities that offer a dementia care program, compared to those that do not offer such a program., Methods: We conducted a population-level cross-sectional study on all licensed assisted living facilities in Ontario, Canada in 2018 (n = 738). Facility-level characteristics (e.g., resident and suite capacities, etc.) and the provision of the other 12 provincially regulated care services (e.g., pharmacist and medical services, skin and wound care, etc.) attributed to assisted living facilities were examined. Multivariable Poisson regression with robust standard errors was used to model the characteristics of assisted living facilities associated with the provision of a dementia care program., Results: There were 123 assisted living facilities that offered a dementia care program (16.7% versus 83.3% no dementia care). Nearly half of these facilities had a resident capacity exceeding 140 older adults (44.7% versus 21.6% no dementia care) and more than 115 suites (46.3% versus 20.8% no dementia care). All assisted living facilities that offered a dementia care program also offered nursing services, meals, assistance with bathing and hygiene, and administered medications. After adjustment for facility characteristics and other provincially regulated care services, the prevalence of a dementia care program was nearly three times greater in assisted living facilities that offered assistance with feeding (Prevalence Ratio [PR] 2.91, 95% Confidence Interval [CI] 1.98 to 4.29), and almost twice as great among assisted living facilities that offered medical services (PR 1.78, 95% CI 1.00 to 3.17), compared to those that did not., Conclusions: A dementia care program was more prevalent in assisted living facilities that housed many older adults, had many suites, and offered at least five of the other 12 regulated care services. Our findings deepen the understanding of specialized care for dementia in assisted living facilities., (© 2021. The Author(s).)

To promote postpandemic recovery, many countries have adopted economic packages that include fiscal, monetary, and financial policy measures; however, the effects of these policies may not be known for several years or more. There is an opportunity for decision makers to learn from past policies that facilitated recovery from other disease outbreaks, crises, and natural disasters that have had a devastating effect on economies around the world. To support the development of the United Nations Research Roadmap for COVID-19 Recovery, this review examined and synthesized peer-reviewed studies and gray literature that focused on macroeconomic policy responses and multilateral coalition strategies from past pandemics and crises to provide a map of the existing evidence. We conducted a systematic search of academic and gray literature databases. After screening, we found 22 records that were eligible for this review. The evidence found demonstrates that macroeconomic and multilateral coalition strategies have various impacts on a diverse set of countries and populations. Although the studies were heterogeneous in nature, most did find positive results for macroeconomic intervention policies that addressed investments to strengthen health and social protection systems, specifically cash and unconventional/nonstandard monetary measures, in-kind transfers, social security financing, and measures geared toward certain population groups.

Background: Visual analytics (VA) promotes the understanding of data with visual, interactive techniques, using analytic and visual engines. The analytic engine includes automated techniques, whereas common visual outputs include flow maps and spatiotemporal hot spots., Objective: This scoping review aims to address a gap in the literature, with the specific objective to synthesize literature on the use of VA tools, techniques, and frameworks in interrelated health care areas of population health and health services research (HSR)., Methods: Using the 2018 PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines, the review focuses on peer-reviewed journal articles and full conference papers from 2005 to March 2019. Two researchers were involved at each step, and another researcher arbitrated disagreements. A comprehensive abstraction platform captured data from diverse bodies of the literature, primarily from the computer and health sciences., Results: After screening 11,310 articles, findings from 55 articles were synthesized under the major headings of visual and analytic engines, visual presentation characteristics, tools used and their capabilities, application to health care areas, data types and sources, VA frameworks, frameworks used for VA applications, availability and innovation, and co-design initiatives. We found extensive application of VA methods used in areas of epidemiology, surveillance and modeling, health services access, use, and cost analyses. All articles included a distinct analytic and visualization engine, with varying levels of detail provided. Most tools were prototypes, with 5 in use at the time of publication. Seven articles presented methodological frameworks. Toward consistent reporting, we present a checklist, with an expanded definition for VA applications in health care, to assist researchers in sharing research for greater replicability. We summarized the results in a Tableau dashboard., Conclusions: With the increasing availability and generation of big health care data, VA is a fast-growing method applied to complex health care data. What makes VA innovative is its capability to process multiple, varied data sources to demonstrate trends and patterns for exploratory analysis, leading to knowledge generation and decision support. This is the first review to bridge a critical gap in the literature on VA methods applied to the areas of population health and HSR, which further indicates possible avenues for the adoption of these methods in the future. This review is especially important in the wake of COVID-19 surveillance and response initiatives, where many VA products have taken center stage., International Registered Report Identifier (irrid): RR2-10.2196/14019., (©Jawad Ahmed Chishtie, Jean-Sebastien Marchand, Luke A Turcotte, Iwona Anna Bielska, Jessica Babineau, Monica Cepoiu-Martin, Michael Irvine, Sarah Munce, Sally Abudiab, Marko Bjelica, Saima Hossain, Muhammad Imran, Tara Jeji, Susan Jaglal.

Background: Visual analytics (VA) promotes the understanding of data using visual, interactive techniques and using analytic and visual engines. The analytic engine includes machine learning and other automated techniques, whereas common visual outputs include flow maps and spatiotemporal hotspots for studying service gaps and disease distribution. The principal objective of this scoping review is to examine the state of science on VA and the various tools, strategies, and frameworks used in population health and health services research (HSR)., Objective: The purpose of this scoping review is to develop an overarching global view of established techniques, frameworks, and methods of VA in population health and HSR. The main objectives are to explore, map, and synthesize the literature related to VA in its application to the two main focus areas of health care., Methods: We will use established scoping review methods to meet the study objective. As the use of the term visual analytics is inconsistent, one of the major challenges was operationalizing the concepts for developing the search strategy, based on the three main concepts of population health, HSR, and VA. We included peer reviewed and grey literature sources from 2005 till March 2019 in the search. Independent teams of researchers will screen the titles, abstracts and full text articles, whereas an independent researcher will arbiter conflicts. Data will be abstracted and presented using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist and explanation by two independent researchers., Results: As of late August 2019, the scoping review is in the full-text screening stage. Data synthesis will follow and the first results are expected to be submitted for publication in December 2019. In this protocol, the methods for undertaking this scoping review are detailed. We present how we operationalized the varied concepts of population health, health services, and VA. The main results of the scoping review will synthesize peer reviewed and grey literature sources on the main methods of VA in the interrelated fields of population health and health services research from January 2005 till March 2019., Conclusions: VA is being increasingly used and integrated with emerging technologies to support decision making using large data sets. This scoping review of the VA tools, strategies, and frameworks applied to population health and health services aims to increase awareness of this approach for uptake by decision makers working within and toward developing learning health systems globally., International Registered Report Identifier (irrid): DERR1-10.2196/14019., (©Jawad Ahmed Chishtie, Jessica Babineau, Iwona Anna Bielska, Monica Cepoiu-Martin, Michael Irvine, Andriy Koval, Jean-Sebastien Marchand, Luke Turcotte, Tara Jeji, Susan Jaglal.

Background: Ankle and foot sprains and fractures are prevalent injuries, which may result in substantial physical and economic consequences for the patient and place a financial burden on the health care system. Therefore, the objectives of this paper are to examine the direct and indirect costs of treating ankle and foot injuries (sprains, dislocations, fractures), as well as to provide an overview of the outcomes of full economic analyses of different treatment strategies., Methods: A systematic review was carried out among seven databases to identify English language publications on the health economics of ankle and foot injury treatment published between 1980 and 2014. The direct and indirect costs were abstracted by two independent reviewers. All costs were adjusted for inflation and reported in 2016 US dollars (USD)., Results: Among 2047 identified studies, 32 were selected for analysis. The direct costs of ankle sprain management ranged from $292 to $2268 per patient (2016 USD), depending on the injury severity and treatment strategy. The direct costs of managing ankle fractures were higher ($1908-$19,555). Foot fracture treatment had similar direct costs ranging from $998 to $21,801. The economic evaluations were conducted from the societal or payer's perspectives., Conclusion: The costs of treating ankle and foot sprains and fractures varied among the studies, mostly due to differences in injury type and study characteristics, which impacted the ability of directly comparing the financial burden of treatment. Nonetheless, the review showed that the costs experienced by the patient and the health care system increased with injury complexity., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Background: Ankle and foot sprains and fractures are common injuries affecting many individuals, often requiring considerable and costly medical interventions. The objectives of this systematic review are to collect, assess, and critically appraise the published literature on the health economics of ankle and foot injury (sprain and fracture) treatment., Methods: A systematic literature review of Ovid MEDLINE, EMBASE, Cochrane DSR, ACP Journal Club, AMED, Ovid Healthstar, and CINAHL was conducted for English-language studies on the costs of treating ankle and foot sprains and fractures published from January 1980 to December 2014. Two reviewers assessed the articles for study quality and abstracted data., Results: The literature search identified 2047 studies of which 32 were analyzed. A majority of the studies were published in the last decade. A number of the studies did not report full economic information, including the sources of the direct and indirect costs, as suggested in the guidelines. The perspective used in the analysis was missing in numerous studies, as was the follow-up time period of participants. Only five of the studies undertook a sensitivity analysis which is required whenever there are uncertainties regarding cost data., Conclusion: This systematic review found that publications do not consistently report on the components of health economics methodology, which in turn limits the quality of information. Future studies undertaking economic evaluations should ensure that their methods are transparent and understandable so as to yield accurate interpretation for assistance in forthcoming economic evaluations and policy decision-making., (Copyright © 2017 Elsevier Ltd.

ABSTRACTMedical issues facing the aging population are of growing concern with consequences for patients and their caregivers. This study determined the indirect and out-of-pocket costs incurred by the caregivers of elderly patients in Canadian Intensive Care Units (ICUs). Primary family caregivers were surveyed capturing out-of-pocket costs, hours of work, and hours of leisure forgone in providing patient care while the patient was in the ICU. Total costs of care per month were reported across caregiver sex, age, and geographic region. Average out-of-pocket costs were $791 (2016 Canadian dollars) in the first month of ICU care. The mean total cost to family caregivers per patient was $162 per day. Male primary caregivers had higher mean out-of-pocket costs than female caregivers. Subsidization programs covering expenses such as travel, meals, accommodation, and parking are needed to support family caregivers of elderly ICU patients who are incurring considerable out-of-pocket costs.

Objective: Ankle sprains are common injuries that may lead to long-term morbidity. Individuals with obesity are at increased risk for ankle sprains; however, prognostic associations between body mass index (BMI) and recovery are less well understood. This study investigated whether BMI status affects recovery from ankle sprains., Methods: We included individuals≥16 years old with grade 1 or 2 ankle sprains who sought emergency department treatment in Kingston, Ontario, Canada. Height in centimeters and weight in kilograms were measured at baseline by using a height rod and a standard medical column scale, respectively. BMI was calculated and categorized as non-overweight,<25.0kg/m 2 ; overweight, 25.0-29.9kg/m 2 ; and obese,≥30kg/m 2 . Recovery was assessed at 1, 3 and 6 months post-injury by the Foot and Ankle Outcome Score (FAOS). Continuous FAOS and binary recovery status were compared by BMI group at each assessment using a repeated measures linear mixed effects model and logistic regression, respectively., Results: In total, 504 individuals were recruited and 6-month follow-up data were collected for 80%. We observed no significant differences in recovery at 1 and 3 months post-injury. At 6 months, between 53% and 66% of the participants were considered to have recovered according to the FAOS. The mean difference in unadjusted FAOS between participants classified as obese and non-overweight was -23.02 (95% confidence interval, -38.99 to -7.05) but decreased after adjusting for confounders. The odds ratio for recovery was 0.60 (0.37-0.97) before adjustment and 0.74 (0.43-1.29) after adjustment. Six-month recovery was significantly lower for participants with obesity than non-overweight participants on the FAOS Pain and Function in Daily Living subscales but were not clinically meaningful., Conclusions: All BMI groups showed improvements from ankle sprain over time. However, at 6 months, a sizeable proportion of the participants had not fully recovered particularly among individuals classified as obese. The findings suggest that individuals with obesity may benefit from specialized interventions focused on symptom management and functional activity., (Copyright © 2018 Elsevier Masson SAS.

Background: We sought to determine whether patients with a coordinated care plan developed using the Health Links model of care in the Hamilton Niagara Haldimand Brant Local Health Integration Network differed in their use of health care (no. of emergency department visits, inpatient admissions, length of inpatient stay) when compared with a matched control group of patients with no care plans., Methods: We performed a propensity score-matched study of 12 months pre- and 12 months post-health care use. Patients who had a coordinated care plan that started between 2013 and 2015 were propensity score matched to patients in a control group. Patient information was obtained from Client Health and Related Information System, National Ambulatory Care Reporting System and Discharge Abstract Database. Differences in health care use pre- and post-index date were compared using the Wilcoxon signed-rank test. A negative binomial regression model was fit for each health care use outcome at 6 and 12 months post-index date., Results: Six hundred coordinated care plan enrollees and 25 449 potential control patients were included in the matching algorithm, which resulted in 548 matched pairs (91.3%). Both groups showed decreases in health care use post-index date. Matched care plan enrollees had significantly fewer emergency department visits at 6 (incidence rate ratio [IRR] 0.81, 95% confidence interval [CI] 0.72-0.91, p < 0.01) and 12 months post-index date (IRR 0.88, 95% CI 0.79-0.99, p < 0.05) compared with the matched controls. Other use parameters were not significantly different between care plan enrollees and the control group., Interpretation: Care plan enrollees show a decrease in the number of times they visit emergency departments, which may be attributed to integrated and coordinated care planning. This association should be examined to see whether these reductions persist for more than 1 year., Competing Interests: Competing interests: None declared., (Copyright 2018, Joule Inc. or its licensors.)

Introduction: Individuals with intellectual disabilities have a higher prevalence of health problems, including psychiatric and behavioural conditions, than the general population. However, there is little population-based information in Canada about individuals with a dual diagnosis of psychiatric disorder and intellectual impairment. The aim of this study was to determine whether the 2005 Canadian Community Health Survey (CCHS) and the 2006 Participation and Activity Limitation Survey (PALS) could be used to estimate the prevalence of dual diagnosis in Canada., Methods: We undertook a secondary analysis of two population-based surveys to determine if these could be used to estimate the prevalence of psychiatric or behavioural conditions among adults with intellectual disabilities in Canada., Results: The surveys reflect prevalence estimates of intellectual disabilities (CCHS: 0.2% and PALS: 0.5%) that are considerably lower than those published in the literature. While it was possible to calculate the proportion of individuals with a dual diagnosis (CCHS: 30.6% and PALS: 44.3%), the surveys were of limited use for detailed analyses. The estimates of prevalence derived from the surveys, especially from the CCHS, were of unacceptable quality due to high sampling variability and selection bias., Conclusion: The estimates should be interpreted with caution due to concerns regarding the representativeness of the sample with intellectual disabilities in the national surveys.
