Introduction. In British Columbia, Aboriginal diabetes prevalence, hospitalization and mortality rates are all more than twice as high as in the rest of the population. We describe and evaluate a program to improve access to diabetes care for Aboriginal people in northern communities. Study design. Cost-effectiveness evaluation. Methods. A diabetes nurse educator and an ophthalmic technician travel to Aboriginal reserves, offering people with diabetes services recommended in current clinical practice guidelines: retinopathy screening by digital retinal fundus photography, glaucoma screening by tonometry, point-of-care urine and blood testing to detect microalbuminuria and dyslipidemia and to measure glycated hemoglobin, foot examinations and foot care advice, blood pressure and height and weight measurement and diabetes care advice. Via electronic communication, an ophthalmologist and an endocrinologist in Vancouver review the findings and supervise the mobile clinic staff. Results. During the first year, 25 clinics were held at 22 sites, examining 339 clients with diabetes. Exit surveys showed high levels of client satisfaction. Mean cost per client (Cdn$1,231) was less than for the alternative, transporting clients to care in the nearest cities (Cdn$1,437). Conclusions. The mobile clinic is cost-effective and improves access to the recommended standard of diabetes care.

BackgroundAboriginal people in British Columbia (BC) have higher injury incidence than the general population, but information is scarce regarding variability among injury categories, time periods, and geographic, demographic and socio-economic groups. Our project helps fill these gaps. This report focuses on workplace injuries.MethodsWe used BC’s universal health care insurance plan as a population registry, linked to worker compensation and vital statistics databases. We identified Aboriginal people by insurance premium group and birth and death record notations. We identified residents of specific Aboriginal communities by postal code. We calculated crude incidence rate and Standardized Relative Risk (SRR) of worker compensation injury, adjusted for age, gender and Health Service Delivery Area (HSDA), relative to the total population of BC. We assessed annual trend by regressing SRR as a linear function of year. We tested hypothesized associations of geographic, socio-economic, and employment-related characteristics of Aboriginal communities with community SRR of injury by multivariable linear regression.ResultsDuring the period 1987–2010, the crude rate of worker compensation injury in BC was 146.6 per 10,000 person-years (95% confidence interval: 146.4 to 146.9 per 10,000). The Aboriginal rate was 115.6 per 10,000 (95% CI: 114.4 to 116.8 per 10,000) and SRR was 0.88 (95% CI: 0.87 to 0.89). Among those living on reserves SRR was 0.79 (95% CI: 0.78 to 0.80). HSDA SRRs were highly variable, within both total and Aboriginal populations. Aboriginal males under 35 and females under 40 years of age had lower SRRs, but older Aboriginal females had higher SRRs. SRRs are declining, but more slowly for the Aboriginal population. The Aboriginal population was initially at lower risk than the total population, but parity was reached in 2006. These community characteristics independently predicted injury risk: crowded housing, proportion of population who identified as Aboriginal, and interactions between employment rate and income, occupational risk, proportion of university-educated persons, and year.ConclusionsAs employment rates rise, so has risk of workplace injury among the Aboriginal population. We need culturally sensitive prevention programs, targeting regions and industries where Aboriginal workers are concentrated and demographic groups that are at higher risk.

Population-level statistics indicating disparities in injury rates between Aboriginal and non-Aboriginal populations disguise considerable community-level heterogeneity. Using an ecological approach, we analyzed linked data from British Columbia's (BC) universal health care insurance plan, worker compensation, vital statistics, and census databases to identify community-level risk markers for hospitalization due to injury among the Aboriginal population of BC, Canada. Community standardized relative risks (SRR) of injury hospitalization relative to the total population of BC ranged from 0.24 to 9.35. Variables associated with increased SRRs included the following: higher proportions of crowded housing, housing in poor condition, participating in industries with greater risk of a work injury claim, being more remote, and at higher latitude. Higher income and more high school graduates were protective. In the best-fitting multivariable model, variables independently associated with SRR were proportion of the population with a high school certificate (RR = 0.89 per unit standard deviation change, 95 % confidence interval 0.83 to 0.94), and remoteness index (RR = 1.06, 95 % confidence interval (CI) 1.01 to 1.11). Results confirm profound diversity in Aboriginal communities across BC. SRRs of injury hospitalization increased as proportion of high school graduates dropped and remoteness increased. Promoting the educational attainment of community members should be an important focus of initiatives to improve health.

BackgroundAboriginal people in British Columbia (BC) have higher injury incidence than the general population. Our project describes variability among injury categories, time periods, and geographic, demographic and socio-economic groups. This report focuses on unintentional falls.MethodsWe used BC’s universal health care insurance plan as a population registry, linked to hospital separation and vital statistics databases. We identified Aboriginal people by insurance premium group and birth and death record notations. We identified residents of specific Aboriginal communities by postal code. We calculated crude incidence and Standardized Relative Risk (SRR) of hospitalization for unintentional fall 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 with community SRR of injury by linear regression.ResultsDuring 1991 through 2010, the crude rate of hospitalization for unintentional fall injury in BC was 33.6 per 10,000 person-years. The Aboriginal rate was 49.9 per 10,000 and SRR was 1.89 (95% confidence interval 1.85-1.94). Among those living on reserves SRR was 2.00 (95% CI 1.93-2.07). Northern and non-urban HSDAs had higher SRRs, within both total and Aboriginal populations. In every age and gender category, the HSDA-standardized SRR was higher among the Aboriginal than among the total population. Between 1991 and 2010, crude rates and SRRs declined substantially, but proportionally more among the Aboriginal population, so the gap between the Aboriginal and total population is narrowing, particularly among females and older adults. These community characteristics were associated with higher risk: lower income, lower educational level, worse housing conditions, and more hazardous types of employment.ConclusionsOver the years, as socio-economic conditions improve, risk of hospitalization due to unintentional fall injury has declined among the Aboriginal population. Women and older adults have benefited more.

BackgroundDisparities in injury rates between Aboriginal and non-Aboriginal populations in British Columbia (BC) are well established. Information regarding the influence of residence on disparities is scarce. We sought to fill these gaps by examining hospitalization rates for all injuries, unintentional injuries and intentional injuries across 24 years among i) Aboriginal and total populations; ii) populations living in metropolitan and non-metropolitan areas; and iii) Aboriginal populations living on- and off-reserve.MethodsWe used data spanning 1986 through 2010 from BC’s universal health care insurance plan, linked to vital statistics databases. Aboriginal people were identified by insurance premium group and birth and death record notations, and their residence was determined by postal code. “On-reserve” residence was established by postal code areas associated with an Indian reserve or settlement. Health Service Delivery Areas (HSDAs) were classified as “metropolitan” if they contained a population of at least 100,000 with a density of 400 or more people per square kilometre. We calculated the crude hospitalization incidence rate and the Standardized Relative Risk (SRR) of hospitalization due to injury standardizing by gender, 5-year age group, and HSDA. We assessed cumulative change in SRR over time as the relative change between the first and last years of the observation period.ResultsAboriginal metropolitan populations living off-reserve had the lowest SRR of injury (2.0), but this was 2.3 times greater than the general British Columbia metropolitan population (0.86). For intentional injuries, Aboriginal populations living on-reserve in non-metropolitan areas were at 5.9 times greater risk than the total BC population. In general, the largest injury disparities were evident for Aboriginal non-metropolitan populations living on-reserve (SRR 3.0); 2.5 times greater than the general BC non-metropolitan population (1.2). Time trends indicated decreasing disparities, with Aboriginal non-metropolitan populations experiencing the largest declines in injury rates.ConclusionsMetropolitan/non-metropolitan residence appears to be a more important predictor than on/off-reserve residence for all injuries and unintentional injuries, and the relationship was even more pronounced for intentional injuries. The persistent disparities highlight the need for culturally sensitive and geographically relevant injury prevention approaches.

BackgroundChildren and youth worldwide are at high risk of injury resulting in morbidity, disability or mortality. Disparities in risk exist between and within countries, and by sex and ethnicity. Our aim is to contribute data on disparities of injury rates for Aboriginal children and youth compared with those of the general population in British Columbia (BC), Canada, by examining risks for the two populations, utilizing provincial administrative data over a 24-year period.MethodsHospital discharge records from the provincial health care database for children and youth were used to identify injury for the years 1986 to 2009. Within the total BC population, the Aboriginal population was identified. Crude rates and standardized relative risks (SRR) of hospitalization were calculated, by year and category of injury type and external cause, and compared to the total BC population for males and females under age 25 years.ResultsOver the 24-year period, substantive decreases were found in hospitalization injury risks for children and youth in both Aboriginal and total populations, for both sexes, and for most categories and types of injuries. Risk in overall injury dropped by 69% for the Aboriginal population and by 66% for the total BC population, yet in every year, the Aboriginal population had a higher risk than the total BC population. There were over 70% declines in risks among females of intentionally inflicted injury by another, among both the Aboriginal and total BC populations. Risk of injury caused by transport vehicles has decreased by an overwhelming 83% and 72% for the Aboriginal male population and for the total BC male population, respectively.ConclusionsThe over 70% declines in risks for females of intentionally inflicted injury by another, among both the Aboriginal and total BC populations is excellent news. Risk of injury caused by transport vehicles for males decreased overwhelmingly for both populations. Disparities in rates between the Aboriginal population and total BC population remain because of similarity in the proportional reductions among the two populations. Since the Aboriginal population started at a much higher risk, in absolute terms, the gap between the two populations is shrinking.

his study describes rates of acute care hospitalization from diabetes mellitus or its complications among residents of the province of British Columbia, Canada during the 5-year period from 1993 to 1997, comparing people with Indian Status to rest of the province's population. METHODS From data extracts provided by the British Columbia Ministry of Health's Information and Analysis Branch, we created a database of all acute care hospital discharges occurring in British Columbia from January 1, 1993 to

First Nations peoples in Canada often face geographic, social and cultural barriers to accessing diabetes care. Diabetes care requires mutual provider-patient understandings, strong relationships and continuity of care. Care that includes screening for complications, assessment of disease status and education can be provided by diabetes nurse educators with telemedicine specialist backup.
