High-Efficiency Particulate Air Filters for Preventing Wildfire-related Asthma Complications: A Cost-Effectiveness Study.

Rationale: Air pollution caused by wildfire smoke is linked to adverse health outcomes, especially for people living with asthma. Objectives: To evaluate whether government rebates for high-efficiency particulate air (HEPA) filters, which reduce concentrations of smoke particles indoors, are cost effective in managing asthma and preventing exacerbations in British Columbia (BC), Canada. Methods: We used a Markov model to analyze health states for asthma control, exacerbation severity, and death over a retrospective time horizon of 5 years (2018-2022). Concentrations of wildfire smoke-derived particulate matter with an aerodynamic diameter ⩽2.5 μm (PM2.5) from the Canadian Optimized Statistical Smoke Exposure Model and relevant literature informed the model. The base-case analysis assumed continuous use of a HEPA filter. Costs and quality-adjusted life-years (QALYs) resulting from varying rebates were computed for each Health Service Delivery Area (HSDA). Measurements and Main Results: In the base-case analysis, HEPA filter use resulted in increased costs of $83.34 (SE, $1.03) and increased QALYs of 0.0011 (SE, 0.0001) per person. The average incremental cost-effectiveness ratio among BC HSDAs was $74,652/QALY (SE, $3,517), with incremental cost-effectiveness ratios ranging from $40,509 to $89,206 per QALY in HSDAs. Across the province, the intervention was projected to prevent 4,418 exacerbations requiring systemic corticosteroids, 643 emergency department visits, and 425 hospitalizations during the 5-year time horizon. A full rebate was cost effective in 1 of the 16 HSDAs across BC. The probability of cost-effectiveness ranged from 0.1% to 74.8% across HSDAs. A $100 rebate was cost effective in most HSDAs. Conclusions: The cost-effectiveness of HEPA filters in managing wildfire smoke-related asthma issues in BC varies by region. Government rebates up to two-thirds of the filter cost are generally cost effective, with a full rebate being cost effective only in Kootenay Boundary.

ICU-Managed Patients' Epidemiology, Characteristics, and Outcomes: A Retrospective Single-Center Study.

Resources are limited, and it is exceedingly difficult to provide intensive care in developing nations. In Somalia, intensive care unit (ICU) care was introduced only a few years ago. In this study, we aimed to determine the epidemiology, characteristics, and outcome of ICU-managed patients in a tertiary hospital in Mogadishu. We retrospectively evaluated the files of 1082 patients admitted to our ICU during the year 2021. The majority (39.7%) of the patients were adults (aged between 20 and 39 years), and 67.8% were male patients. The median ICU length of stay was three days (IQR = 5 days), and nonsurvivors had shorter stays, one day. The mortality rate was 45.1%. The demand for critical care services in low-income countries is high. The country has a very low ICU bed capacity. Critical care remains a neglected area of health service delivery in this setting, with large numbers of patients with potentially treatable conditions not having access to such services.

Testing a Theory-Driven Intervention with/without Care Manager Support on Physicians’ ADHD Practices: Rethinking What Works

Objective: To understand the benefits of an intensive 6-months-long training program (with or without assistance of an embedded care manager) on primary care providers’ (PCPs’) adoption of evidence-based practices for diagnosing and managing Attention-Deficit/Hyperactivity Disorder (ADHD). Methods: Following an intensive weekend training in primary care pediatric mental health service delivery, 47 PCPs were randomly assigned to 6 months of ongoing educational support via twice-monthly conference calls, either with or without additional assistance of a care manager. In addition to the impact of a care manager, basic science-derived predictors of behavior change were examined to explore impact on PCPs’ initial and subsequent intentions/decisions to adopt 11 specific changes in ADHD practices. Effects of practice obstacles on PCPs’ practice decisions, both initially and over 6 months, were also examined. Results: PCPs’ initial and subsequent decisions to employ program-targeted ADHD evidence-based practices increased over time and were significantly predicted by underlying hypothesized predictors. Additional support of a care manager had minimal effects on PCPs’ initial and subsequent decisions to apply specific evidence-based ADHD practices. Of note, PCPs’ initial worries/perceptions concerning practice obstacles decreased significantly over time, likely due to twice-monthly support calls. Conclusions: With intensive and sustained support, PCPs will adopt most evidence-based practices for ADHD diagnosis and treatment. Many initially anticipated obstacles dissipated over time. Additional support of care managers had little impact on PCPs’ longitudinal decisions to adhere to ADHD practice guidelines. Basic science predictors of behavior change are robust correlates of PCPs’ practice changes and should be more routinely applied to understand and improve training outcomes in multiple areas of health service delivery.

Racial/Ethnic Variation in Veterans Health Administration COVID-19 Vaccine Uptake

IntroductionEquitable COVID-19 vaccine access is imperative to mitigating negative COVID-19 impacts among racial/ethnic minorities. U.S. racial/ethnic minorities have lower COVID-19 vaccination rates than Whites despite higher COVID-19 death/case rates. The Veterans Health Administration provides the unique context of a managed care system with few access barriers. This study evaluates race/ethnicity as a predictor of Veterans Health Administration COVID-19 vaccination.MethodsThe cohort was composed of Veterans Health Administration outpatient users aged ≥65 years (N=3,474,874). COVID-19 vaccination was assessed between December 14, 2020 and February 23, 2021. Multivariable logistic regressions were conducted, controlling for demographics, medical comorbidity, and influenza vaccination history. Proximity to Indian Health Service Contract Health Service Delivery Areas was tested as a moderator. Data analyses were conducted during 2021.ResultsBlacks (OR=1.28, 95% CI=1.17, 1.40), Hispanics (OR=1.15, 95% CI=1.05, 1.25), and Asians (OR=1.21, 95% CI=1.02, 1.43) were more likely than Whites to receive Veterans Health Administration COVID-19 vaccinations. American Indian/Alaska Natives were less likely than Whites to receive Veterans Health Administration COVID-19 vaccinations, but only those residing in Contract Health Service Delivery Area counties (OR= 0.58, 95% CI= 0.47, 0.72). Influenza vaccine history positively predicted COVID-19 vaccine uptake (OR= 2.28, 95% CI=2.22, 2.34).ConclusionsIn the Veterans Health Administration, compared with the general U.S. population, COVID-19 vaccine receipt is higher among most racial/ethnic minority groups than Whites, suggesting reduced vaccination barriers . The Indian Health Service may provide a safety net for American Indian/Alaska Native populations. Addressing vaccination access barriers in non–Veterans Health Administration settings can potentially reduce racial/ethnic disparities.

The Role of Community-Level Factors on Disparities in COVID-19 Infection Among American Indian/Alaska Native Veterans.

ObjectivesAmerican Indian and Alaska Native (AI/AN) communities have been disproportionately affected by the coronavirus disease 2019 (COVID-19) pandemic. This study examines whether neighborhood characteristics mediate AI/AN versus White-non-Hispanic Veteran COVID-19 infection disparities, and whether mediation differs based on proximity to reservations.MethodsUsing Veteran Health Administration’s (VHA) national database of VHA users evaluated for COVID-19 infection (3/1/2020–8/25/2020), we examined whether census tract neighborhood characteristics (percent households overcrowded, without complete plumbing, without kitchen plumbing, and neighborhood socioeconomic status [n-SES]) mediated racial disparities in COVID-19 infection, using inverse odds-weighted logistic models controlling for individual-level characteristics. Using moderated mediation analyses, we assessed whether neighborhood mediating effects on disparities differed for those residing in counties containing/near federally recognized tribal lands (i.e., Contract Health Service Delivery Area [CHSDA] counties) versus not.ResultsThe percent of households without complete plumbing, percent without kitchen plumbing, and n-SES partially mediated AI/AN-White-non-Hispanic COVID-19 infection disparities (accounting for 17–35% of disparity) to a similar extent in CHSDA and non-CHSDA counties. The percent of households without kitchen plumbing had stronger mediating effects for CHSDA than non-CHSDA residents.ConclusionsNeighborhood-level social determinants of health may contribute to the disproportionate COVID-19 infection burden on AI/ANs; differences are exacerbated among AI/ANs living near reservations.

Trends and Regional Variation in Prevalence of Cardiovascular Risk Factors and Association With Socioeconomic Status in Canada, 2005-2016

Cardiovascular disease remains the second leading cause of death in Canada. Monitoring and tracking the trends and disparities in major cardiovascular risk factors could provide benchmarks for future cardiovascular health strategies. To investigate the temporal trends, regional variations, and socioeconomic disparities in major cardiovascular risk factors in Canada from 2005 to 2016. This repeated cross-sectional survey study included adults aged 20 years and older from 6 Canadian Community Health Survey cycles between 2005 and 2016. Cardiovascular risk factors included hypertension, diabetes, obesity, and current smoking. Socioeconomic status was measured using equivalized household income. Data analysis was performed from September 2019 to April 2020. A total of 112 health regions and socioeconomic status. Age- and sex-adjusted prevalence of hypertension, diabetes, obesity, and current smoking by year; health regions; and socioeconomic status. Absolute numbers were rounded to base 100 for confidentiality purposes, and percentages were based on weighted numbers. Slope index of inequality (SII) and relative index of inequality (RII) were calculated to assess absolute and relative socioeconomic inequalities, respectively. A total of 670 000 respondents (329 000 [49.1%] men; 341 000 [50.9%] women) aged 20 years and older from 6 survey cycles were enrolled for this study. The largest age group was those aged 40 to 59 years (eg, 2005 cycle: 40.2% [95% CI, 39.9%-40.6%]). In the 2015/2016 cycle, the overall age- and sex-adjusted prevalence rates of hypertension, diabetes, obesity, and current smoking were 20.7% (95% CI, 20.4%-21.1%), 7.2% (95% CI, 7.0%-7.5%), 20.1% (95% CI, 19.7%-20.6%), and 17.8% (95% CI, 17.4%-18.2%), respectively. From 2005 to 2016, there was a significant increase in the prevalence of hypertension, diabetes, and obesity (eg, prevalence of diabetes in both sexes, 2005: 5.8% [95% CI, 5.6%-6.0%]; 2015/2016: 7.2% [95% CI, 7.0%-7.5%]; P < .001) but a significant decrease in the prevalence of current smoking (both sexes, 2005: 22.1% [95% CI, 21.7%-22.5%]; 2015/2016: 17.8% [95% CI, 17.4%-18.2%]; P < .001). The prevalence of all the risk factors varied widely across health regions (eg, obesity, Vancouver Health Service Delivery Area: 6.7% [95% CI, 4.5%-9.0%]; Miramichi Area: 36.8% [95% CI, 27.3%-46.3%]). In addition to obesity among men, all risk factors tended to be more common among those with lower income (eg, prevalence of hypertension in both sexes, 2015/2016, lowest income group: 23.2% [95% CI, 22.4%-24.0%]; highest income group: 18.4% [95% CI, 17.7%-19.1%]). The SII and RII indicated consistent absolute and relative socioeconomic inequalities in hypertension, diabetes, and current smoking over time (eg, RII for hypertension in both sexes, 2005: 1.25; 95% CI, 1.18-1.33; 2015/2016: 1.34; 95% CI, 1.26-1.43). However, the phenomenon of absolute and relative socioeconomic inequalities in obesity was only observed among women (eg, RII for 2015/2016 for obesity in women; 1.74 (95% CI, 1.56-1.93); men: 1.09; 95% CI, 0.99-1.21). During the study period, the prevalence of hypertension, diabetes, and obesity significantly increased, while the prevalence of current smoking significantly decreased. Geographic and socioeconomic gaps should be considered and addressed in future interventions and policies targeted at reducing these cardiovascular risk factors in Canada.

Staying Ahead of the Epidemiologic Curve: Evaluation of the British Columbia Asthma Prediction System (BCAPS) During the Unprecedented 2018 Wildfire Season.

Background: The modular British Columbia Asthma Prediction System (BCAPS) is designed to reduce information burden during wildfire smoke events by automatically gathering, integrating, generating, and visualizing data for public health users. The BCAPS framework comprises five flexible and geographically scalable modules: (1) historic data on fine particulate matter (PM2.5) concentrations; (2) historic data on relevant health indicator counts; (3) PM2.5 forecasts for the upcoming days; (4) a health forecasting model that uses the relationship between (1) and (2) to predict the impacts of (3); and (5) a reporting mechanism.Methods: The 2018 wildfire season was the most extreme in British Columbia history. Every morning BCAPS generated forecasts of salbutamol sulfate (e.g., Ventolin) inhaler dispensations for the upcoming days in 16 Health Service Delivery Areas (HSDAs) using random forest machine learning. These forecasts were compared with observations over a 63-day study period using different methods including the index of agreement (IOA), which ranges from 0 (no agreement) to 1 (perfect agreement). Some observations were compared with the same period in the milder wildfire season of 2016 for context.Results: The mean province-wide population-weighted PM2.5 concentration over the study period was 22.0 μg/m3, compared with 4.2 μg/m3 during the milder wildfire season of 2016. The PM2.5 forecasts underpredicted the severe smoke impacts, but the IOA was relatively strong with a population-weighted average of 0.85, ranging from 0.65 to 0.95 among the HSDAs. Inhaler dispensations increased by 30% over 2016 values. Forecasted dispensations were within 20% of the observed value in 71% of cases, and the IOA was strong with a population-weighted average of 0.95, ranging from 0.92 to 0.98. All measures of agreement were correlated with HSDA population, where BCAPS performance was better in the larger populations with more moderate smoke impacts. The accuracy of the health forecasts was partially dependent on the accuracy of the PM2.5 forecasts, but they were robust to over- and underpredictions of PM2.5 exposure.Conclusions: Daily reports from the BCAPS framework provided timely and reasonable insight into the population health impacts of predicted smoke exposures, though more work is necessary to improve the PM2.5 and health indicator forecasts.

Access to Healthcare Following Serious Injury: Perspectives of Allied Health Professionals in Urban and Regional Settings.

Barriers to accessing healthcare exist following serious injury. These issues are not well understood and may have dire consequences for healthcare utilisation and patients’ long-term recovery. The aim of this qualitative study was to explore factors perceived by allied health professionals to affect access to healthcare beyond hospital discharge for people with serious injuries in urban and regional Victoria, Australia. Twenty-five semi-structured interviews were conducted with community-based allied health professionals involved in post-discharge care for people following serious injury across different urban and regional areas. Interview transcripts were analysed using thematic analysis. Many allied health professionals perceived that complex funding systems and health services restrict access in both urban and regional areas. Limited availability of necessary health professionals was consistently reported, which particularly restricted access to mental healthcare. Access to healthcare was also felt to be hindered by a reliance on others for transportation, costs, emotional stress and often lengthy time of travel. Across urban and regional areas, a number of factors limit access to healthcare. Better understanding of health service delivery models and areas for change, including the use of technology and telehealth, may improve equitable access to healthcare.

Estimates of opioid use disorder prevalence from a regression-based multi-sample stratified capture-recapture analysis

BackgroundAn epidemic of opioid overdose has spread across North America, with illicit drug-related overdose emerging as a leading cause of death in recent years. Estimates of opioid use disorder (OUD) prevalence at the level of the public health service delivery area are needed to project resource needs and identify priority areas for targeted intervention. Our objective is to estimate the annual prevalence of OUD in British Columbia (BC), Canada, from 2000 to 2017. MethodsWe performed a multi-sample stratified capture-recapture analysis to estimate OUD prevalence in BC. The analysis included individuals identified from 3 administrative databases for 2000–2011 and 4 databases for 2012–2017, linked at the individual level. Negative binomial regression models on the counts of individuals within these strata were used to estimate prevalence, adjusting for dependency between databases. ResultsOUD prevalence in BC among people aged 12 years or older was 1.00 % (N = 34,663 individuals) in 2000 and increased to 1.54 % (N = 61,080) in 2011. Between 2013 and 2017 prevalence increased from 1.57 % (95 % confidence interval: 1.56–1.58) to 1.92 % (1.89–1.95; N = 83,760; 82,492-84,855). The greatest increases in prevalence were observed among males 12–30 years old and 31–44 years old, with 43.2 % and 40.2 % increases from 2013 to 2017. ConclusionsIn BC, the OUD prevalence was 1.92 % among people 12 years or older in 2017. We estimated that prevalence has nearly doubled since 2000, with the highest increases in prevalence observed among males under 45.

Regional variation in multimorbidity prevalence in British Columbia, Canada: a cross-sectional analysis of Canadian Community Health Survey data, 2015/16.

Multimorbidity represents a major concern for population health and service delivery planners. Information about the population prevalence (absolute numbers and proportions) of multimorbidity among regional health service delivery populations is needed for planning for multimorbidity care. In Canada, health region-specific estimates of multimorbidity prevalence are not routinely presented. The Canadian Community Health Survey (CCHS) is a potentially valuable source of data for these estimates. Data from the 2015/16 cycle of the CCHS for British Columbia (BC) were used to estimate and compare multimorbidity prevalence (3+ chronic conditions) through survey-weighted analyses. Crude frequencies and proportions of multimorbidity prevalence were calculated by BC Health Service Delivery Area (HSDA). Logistic regression was used to estimate differences in multimorbidity prevalence by HSDA, adjusting for known confounders. Multiple imputation using chained equations was performed for missing covariate values as a sensitivity analysis. The definition of multimorbidity was also altered as an additional sensitivity analysis. A total of 681 921 people were estimated to have multimorbidity in BC (16.9% of the population) in 2015/16. Vancouver (adj-OR = 0.65; 95% CI: 0.44-0.97) and Richmond (adj-OR = 0.55; 95% CI: 0.37-0.82) had much lower prevalence of multimorbidity than Fraser South (reference HSDA). Missing data analysis and sensitivity analysis showed results consistent with the main analysis. Multimorbidity prevalence estimates varied across BC health regions, and were lowest in Vancouver and Richmond after controlling for multiple potential confounders. There is a need for provincial and regional multimorbidity care policy development and priority setting. In this context, the CCHS represents a valuable source of information for regional multimorbidity analyses in Canada.

Geographic variation in the costs of medical care for people living with HIV in British Columbia, Canada

BackgroundRegional variation in medical care costs can indicate heterogeneity in clinical practice, inequities in access, or inefficiencies in service delivery. We aimed to estimate regional variation in medical costs for people living with HIV (PLHIV), adjusting for demographics and case-mix.MethodsWe conducted a retrospective cohort study using linked health administrative databases of PLHIV, from 2010 to 2014, in British Columbia (BC), Canada. Quarterly health care costs (2018 CAD) were derived from inpatient, outpatient, prescription drugs, antiretroviral therapy (ART), and HIV diagnostics. We used a two-part model with a logit link for the probability of incurring costs, and a log link and gamma distribution for observations with positive costs. We also estimated quarterly utilization rates for hospitalization-, physician billing- and prescription drug-days. Primary variables were indicators of individuals’ Health Service Delivery Area (HSDA). We adjusted cost and utilization estimates for demographic characteristics, HIV-disease progression, and comorbidities.ResultsOur cohort included 9577 PLHIV (median age 45.5 years, 80% male). Adjusted total quarterly costs for all 16 HSDAs were within 20% of the provincial mean, 8/16 for hospitalization costs, 16/16 for physician billing costs and 10/16 for prescription drug costs. Northern Interior and Northeast HSDAs had 38 and 44% lower quarterly non-ART prescription drug costs, and 2 and 5% higher quarterly inpatient costs, respectively.ConclusionsWe observed limited variation in medical care costs and utilization among PLHIV in BC. However, lower levels of outpatient care and higher levels of inpatient care indicate possible barriers to accessing care among PLHIV in the most rural regions of the province.

Why should public health agencies across Canada conduct climate change and health vulnerability assessments?

Climate change is increasingly impacting population health outcomes related to several areas of public health service delivery across Canada, and internationally. As a result, public health practitioners are increasingly looking for guidance on how to begin planning for and adapting to a myriad of health-related climate impacts. This paper outlines several benefits for local or regional health agencies in conducting climate change and health vulnerability assessments (CCHVAs), based on the author's experience in conducting two of Canada's first comprehensive assessments. These benefits include, but are not limited to establishing suitable baseline understandings of past, present, and future climate-related health risks; providing guidance on mechanisms to reduce health inequities that may be exacerbated by climate change; generating credibility for health agencies to engage with climate change and pursue collaborative, intersectoral relationships with a range of likely and unlikely allies; identifying suitable, cost-effective adaptation options in the form of public health programming; and encouraging decision-makers to produce proactive policy actions to redress potential climate impacts on population health. Completing a CCHVA can directly optimize health agencies' and their allies' efforts to respond to the health imperatives associated with climate change, while also fueling adaptation options that yield co-benefits across a variety of sectors.

Traditions of research in community mental health care planning and care coordination: A systematic meta-narrative review of the literature.

ContextIn response to political and social factors over the last sixty years mental health systems internationally have endeavoured to transfer the delivery of care from hospitals into community settings. As a result, there has been increased emphasis on the need for better quality care planning and care coordination between hospital services, community services and patients and their informal carers. The aim of this systematic review of international research is to explore which interventions have proved more or less effective in promoting personalized, recovery oriented care planning and coordination for community mental health service users.MethodsA systematic meta-narrative review of research from 1990 to the present was undertaken. From an initial return of 3940 papers a total of 50 research articles fulfilled the inclusion criteria, including research from the UK, Australia and the USA.FindingsThree research traditions are identified consisting of (a) research that evaluates the effects of government policies on the organization, management and delivery of services; (b) evaluations of attempts to improve organizational and service delivery efficiency; (c) service-users and carers experiences of community mental health care coordination and planning and their involvement in research. The review found no seminal papers in terms of high citation rates, or papers that were consistently cited over time. The traditions of research in this topic area have formed reactively in response to frequent and often unpredictable policy changes, rather than proactively as a result of intrinsic academic or intellectual activity. This may explain the absence of seminal literature within the subject field. As a result, the research tradition within this specific area of mental health service delivery has a relatively short history, with no one dominant researcher or researchers, tradition or seminal studies amongst or across the three traditions identified.ConclusionsThe research findings reviewed suggests a gap has existed internationally over several decades between policy aspirations and service level interventions aimed at improving personalised care planning and coordination and the realities of everyday practices and experiences of service users and carers. Substantial barriers to involvement are created through poor information exchange and insufficient opportunities for care negotiation.

Impact of school health management committees on health services delivery in Ghana: A national level assessment.

To examine the prevalence, determinants, and impact of local school health management committees on implementation of minimum-recommended school health services delivery among basic and secondary schools in Ghana. National level cross-sectional data from the first-ever assessment of Ghana Global-School Health Policies and Practices Survey was utilized. Complex sample analyses were used to quantify school-level implementation of recommended minimum package for health services delivery. Of 307 schools, 98% were basic and government run, and 33% offered at least half of the recommended health service delivery areas measured. Schools with a school health management committee (53%) were 4.8 (95% CI=3.23-5.18) times as likely to offer at least 50% of the minimum health services package than schools that did not. There is significant deficit concerning delivery of school health services in schools across Ghana. However, school health management committees positively impact implementation of health service delivery. School health management committees provide a significant impact on delivery of school health services; thus, it is recommended that policy makers and programmers place greater emphasis on the value and need for these advisory boards in all Ghanaian schools.

Development of consensus on models of care in adults with intestinal failure using a modified Delphi approach.

The aims of this study were to establish consensus on service delivery models for management of Type III intestinal failure (IF) and home parenteral nutrition (HPN) within the Australian health-care system and to identify barriers and enablers in moving towards this ideal model. A modified Delphi methodology was utilized to survey experts working in Type III IF HPN. The panel comprised physicians, dietitians, nurses, and pharmacists from 18 of the 20 adult Type III IF HPN centres across Australia. The study consisted of two rounds of email administered questionnaires developed around four key areas of health service delivery: access to services, clinical care, service guidance, and models of care. Open-ended responses were evaluated via an inductive thematic approach to identify areas of consensus. Experts reviewed the final report to consolidate consensus and validity. There was >80% consensus that an ideal team should consist of a physician, nurse, dietitian, pharmacist, and access to psychological support. Consensus supported the need for updated guidelines (75%) and a hub and spoke model of care (82%). However, further consultation is required in order to establish consensus around the use of HPN in the palliative oncology setting (69%). This consensus provides a framework within which health professionals, managers, policy-makers, and consumer groups can move towards optimal management for Type III IF HPN patients. Advocacy and a review of service delivery across Australia are now required to facilitate the ideal model of care identified.

Hospitalizations due to unintentional transport injuries among Aboriginal population of British Columbia, Canada: Incidence, changes over time and ecological analysis of risk markers.

BackgroundWorldwide, Indigenous people have disproportionately higher rates of transport injuries. We examined disparities in injury-related hospitalizations resulting from transport incidents for three population groups in British Columbia (BC): total population, Aboriginal off-reserve, and Aboriginal on-reserve populations. We also examined sociodemographic, geographic and ethnic risk markers for disparities.MethodsWe identified Aboriginal people through BC’s universal health care insurance plan insurance premium group and birth and death record notations. We calculated crude incidence rate and Standardized Relative Risk (SRR) of hospitalization for unintentional transport injury, standardized for age, gender and Health Service Delivery Area (HSDA), relative to the total population of BC. We tested hypothesized associations of geographic, socio-economic, and employment-related characteristics of Aboriginal communities with SRR of transport injury by multivariable linear regression.ResultsDuring the period 1991–2010, the SRR for the off-reserve Aboriginal population was 1.77 (95% CI: 1.71 to 1.83); and 2.00 (95% CI: 1.93 to 2.07) among those living on-reserve. Decline in crude rate and SRRs was observed over this period among both the Aboriginal and total populations of BC, but was proportionally greater among the Aboriginal population. The best-fitting multivariable risk marker model was an excellent fit (R2 = 0.912, p<0.001), predicted SRRs very close to observed values, and retained the following terms: urban residence, population per room, proportion of the population with a high school certificate, proportion of the population employed; and multiplicative interactions of Aboriginal ethnicity with population per room and proportion of the population employed.ConclusionsDisparities in risk of hospitalization due to unintentional transport injury have narrowed. Aboriginal ethnicity modifies the effects of socioeconomic risk factors. Continued improvement of socioeconomic conditions and implementation of culturally relevant injury prevention interventions are needed.

Intentional injury among the indigenous and total populations in British Columbia, Canada: trends over time and ecological analyses of risk

BackgroundOur objective was to explore intentional injury disparity between Indigenous populations and the total population in the province of British Columbia (BC), Canada. We focus on hospitalizations, including both self-inflicted injuries and injuries inflicted by others.MethodsWe used data from BC’s universal health care insurance plan, 1991 to 2010, linked to Vital Statistics databases. Indigenous people were identified through the insurance premium group, and birth and death records. Place of residence was identified through postal code. We calculated crude hospitalization incidence rates and the Standardized Relative Risk (SRR) of hospitalization, standardized by gender, 5-year age group, and Health Service Delivery Area (HSDA). With HSDA populations as the units of observation, linear regression was used to test hypothesized associations of Indigenous ethnicity, geographic, and socio-economic characteristics with SRR of injury.ResultsDuring the period 1991–2010, the crude rate of hospitalization for intentional injuries was 8.4 per 10,000 person-years (95% confidence interval (CI): 8.3 to 8.5) for the total BC population, compared to 45.3 per 10,000 (95% CI: 44.5 to 46.1) for the Indigenous population. For both populations, risk declined over the period for injuries self-inflicted and inflicted by others. The linear regression model predicts that the off-reserve Indigenous population will have SRR of intentional injury 3.98 greater, and the on-reserve Indigenous population 4.17, greater than the total population. The final model was an excellent fit (R2 = 0.912, F = 177.632, p < 0.001), and found that three variables - occupational risk, high school diploma, and university degree – each provide independent effects when interacting multiplicatively with Indigenous ethnicity.ConclusionsThe observation of substantially declining rates of intentional injury for both the Indigenous and total BC populations is off-set by the high disparity in risk between the two populations, which will likely continue until Canada reduces disparity with respect to discriminatory practices, and physical, social, and economic conditions.

Key performance indicators for Australian mental health court liaison services.

The aim of this paper is to describe the development and technical specifications of a framework and national key performance indicators (KPIs) for Australian mental health Court Liaison Services (CLSs) by the National Mental Health Court Liaison Performance Working Group (Working Group). Representatives from each Australian State and Territory were invited to form a Working Group. Through a series of national workshops and meetings, a framework and set of performance indicators were developed using a review of literature and expert opinion. A total of six KPIs for CLSs have been identified and a set of technical specifications have been formed. This paper describes the process and outcomes of a national collaboration to develop a framework and KPIs. The measures have been developed to support future benchmarking activities and to assist services to identify best practice in this area of mental health service delivery.

Social and Geographic Determinants of Hysterectomy in Ontario: A Population-Based Retrospective Cross-Sectional Analysis

ObjectivesThis study sought to determine whether social factors (neighbourhood education and income) and geographic factors (urban or rural dwelling and local service area) are associated with hysterectomy rates, proportion of hysterectomies performed minimally invasively, and hysterectomy complication and readmission rates in Ontario. MethodsThe Canadian Institute for Health Information Discharge Abstract Database was used to perform a population-based retrospective cross-sectional study on women who had an abdominal, vaginal, and laparoscopic hysterectomy in 2007 for benign gynaecologic conditions in hospitals in Ontario, Canada. Crude and age-standardized rates of hysterectomy, proportion of hysterectomy performed minimally invasively (vaginal or laparoscopic), and rates of surgical complications were analyzed by neighbourhood educational attainment, neighbourhood income, rural or urban residency, and health service delivery area (Canadian Task Force Classification of Study Design II). ResultsA total of 13 511 women who underwent hysterectomy were included. Age-standardized hysterectomy rates were higher for the lowest neighbourhood educational quartile compared with the highest (relative risk [RR] 1.49; 95% CI 1.39–1.60), higher with rural compared with urban dwelling (RR 1.54; 95% CI 1.47–1.61), varied with local health service delivery area (Local Health Integration Network [LHIN]) (range 133.4–439.5 per 100 000 women), and also varied non-linearly with neighbourhood income quintile. Proportion of hysterectomies performed minimally invasively did not vary with neighbourhood education or income, were higher for rural compared with urban areas (RR 1.10; 95% CI 1.03–1.19), and varied with LHIN (range 30.0–62.9 per 100 hysterectomies). Surgical complications varied with neighbourhood educational quartile, but not with income or urban or rural residence. ConclusionsConsiderable social and geographic variation exists in rates of hysterectomy in Ontario, whereas only geographic variation is seen in use of minimally invasive routes. Surgical complication rates vary only by neighbourhood education. Such findings suggest inequities in hysterectomy practice in Ontario, and there is a need to evaluate factors influencing patients' decision making, physicians' clinical and surgical practice, and health system policies to help address the observed disparities.

Perspectives of older people about contingency planning for falls in the community: A qualitative meta-synthesis.

ObjectiveDespite consistent evidence for the positive impact of contingency planning for falls in older people, implementation of plans often fail. This is likely due to lack of recognition and knowledge about perspectives of older people about contingency planning. The objective of this research was to explore the perspectives of older people living in the community about use of contingency planning for getting help quickly after a fall.MethodA systematic literature search seeking qualitative research was conducted in April 2014, with no limit placed on date of publication. Medline, EMBASE, Ageline, CINAHL, HealthSource- Nursing/Academic Edition, AMED and Psych INFO databases were searched. Three main concepts were explored and linked using Boolean operators; older people, falls and contingency planning. The search was updated until February 2016 with no new articles found. After removal of duplicates, 562 articles were assessed against inclusion and exclusion criteria resulting in six studies for the meta-synthesis. These studies were critically appraised using the McMaster critical appraisal tool. Bespoke data extraction sheets were developed and a meta-synthesis approach was adopted to extract and synthesise findings.FindingsThree themes of ‘a mix of attitudes’, ‘careful deliberations’ and ‘a source of anxiety’ were established. Perspectives of older people were on a continuum between regarding contingency plans as necessary and not necessary. Levels of engagement with the contingency planning process seemed associated with acceptance of their risk of falling and their familiarity with available contingency planning strategies.ConclusionAvoiding a long lie on the floor following a fall is imperative for older people in the community but there is a lack of knowledge about contingency planning for falls. This meta-synthesis provides new insights into this area of health service delivery and highlights that implementation of plans needs to be directed by the older people rather than the health professionals.
