Disparities in healthcare utilisation rates for Aboriginal and non-Aboriginal Albertan residents, 1997-2006: a population database study.

ABSTRACT:

Background

It is widely recognised that significant discrepancies exist between the health of indigenous and non-indigenous populations. Whilst the reasons are incompletely defined, one potential cause is that indigenous communities do not access healthcare to the same extent. We investigated healthcare utilisation rates in the Canadian Aboriginal population to elucidate the contribution of this fundamental social determinant for health to such disparities.

Methods

Healthcare utilisation data over a nine-year period were analysed for a cohort of nearly two million individuals to determine the rates at which Aboriginal and non-Aboriginal populations utilised two specialties (Cardiology and Ophthalmology) in Alberta, Canada. Unadjusted and adjusted healthcare utilisation rates obtained by mixed linear and Poisson regressions, respectively, were compared amongst three population groups - federally registered Aboriginals, individuals receiving welfare, and other Albertans.

Results

Healthcare utilisation rates for Aboriginals were substantially lower than those of non-Aboriginals and welfare recipients at each time point and subspecialty studied [e.g. During 2005/06, unadjusted Cardiology utilisation rates were 0.28% (Aboriginal, n = 97,080), 0.93% (non-Aboriginal, n = 1,720,041) and 1.37% (Welfare, n = 52,514), p = <0.001]. The age distribution of the Aboriginal population was markedly different [2.7%≥65 years of age, non-Aboriginal 10.7%], and comparable utilisation rates were obtained after adjustment for fiscal year and estimated life expectancy [Cardiology: Incidence Rate Ratio 0.66, Ophthalmology: IRR 0.85].

Discussion

The analysis revealed that Aboriginal people utilised subspecialty healthcare at a consistently lower rate than either comparatively economically disadvantaged groups or the general population. Notably, the differences were relatively invariant between the major provincial centres and over a nine year period. Addressing the causes of these discrepancies is essential for reducing marked health disparities, and so improving the health of Aboriginal people.

Project description:IntroductionEmergency medicine (EM) residency programs have variable approaches to educating residents on recognizing and managing healthcare disparities. We hypothesized that our curriculum with resident-presented lectures would increase residents' sense of cultural humility and ability to identify vulnerable populations.MethodsAt a single-site, four-year EM residency program with 16 residents per year, we designed a curriculum intervention from 2019-2021 where all second-year residents selected one healthcare disparity topic and gave a 15-minute presentation overviewing the disparity, describing local resources, and facilitating a group discussion. We conducted a prospective observational study to assess the impact of the curriculum by electronically surveying all current residents before and after the curriculum intervention. We measured attitudes on cultural humility and ability to identify healthcare disparities among a variety of patient characteristics (race, gender, weight, insurance, sexual orientation, language, ability, etc). Statistical comparisons of mean responses were calculated using the Mann-Whitney U test for ordinal data.ResultsA total of 32 residents gave presentations that covered a broad range of vulnerable patient populations including those that identify as Black, migrant farm workers, transgender, and deaf. The overall survey response was 38/64 (59.4%) pre-intervention and 43/64 (67.2%) post-intervention. Improvements were seen in resident self-reported cultural humility as measured by their responsibility to learn (mean responses of 4.73 vs 4.17; P < 0.001) and responsibility to be aware of different cultures (mean responses of 4.89 vs 4.42; P < 0.001). Residents reported an increased awareness that patients are treated differently in the healthcare system based on their race (P < 0.001) and gender (P < 0.001). All other domains queried, although not statistically significant, demonstrated a similar trend.ConclusionThis study demonstrates increased resident willingness to engage in cultural humility and the feasibility of resident near-peer teaching on a breadth of vulnerable patient populations seen in their clinical environment. Future studies may query the impact this curriculum has on resident clinical decision-making.

Project description:BackgroundFoot and ankle problems are highly prevalent in the general community and a substantial proportion of people seek surgical treatment to alleviate foot pain and deformity. However, the epidemiology of foot and ankle surgery has not been examined in detail. Therefore, the aim of this study was to examine patterns and costs of private sector foot surgery provision in Australia.MethodsData pertaining to all foot and ankle surgical procedures for the calendar years 1997-2006 were extracted from the Australian Medicare Benefits Schedule (MBS) database and were cross-tabulated by sex and age. Descriptive analyses were undertaken to assess sex and age differences in the number and type of procedures performed and to assess for temporal trends over the ten year assessment period. The total cost to Medicare of subsiding surgeons' fees in 2006 was also determined.ResultsDuring the 1997-2006 period, 996,477 surgical procedures were performed on the foot and ankle by private surgeons in Australia. Approximately equal numbers of procedures were performed on males (52%) and females (48%). However, males were more likely to undergo toenail, ankle, clubfoot, tarsal coalition and congenital vertical talus surgery, whereas females were more likely to undergo lesser toe, first metatarsophalangeal joint (MPJ), neuroma, heel, rearfoot and lesser MPJ surgery. The total number of procedures was stable over the assessment period, however there was a relative increase in the number of procedures performed on people aged over 55 years. The total contribution of Medicare to subsiding surgeons' fees for procedures performed in 2006 was $14 M.ConclusionFoot and ankle surgery accounts for a considerable degree of healthcare expenditure in Australia, and the number of procedures in those aged over 55 years is increasing. Given the ageing demographics of the Australian population, the future public health and economic impact of foot morbidity is likely to be substantial. Strategies need to be implemented to ensure that the surgical labour force is adequate to address this increasing demand.

Project description:ObjectiveTo determine medical needs, demographic characteristics and healthcare utilisation patterns of the top 1% and top 2%-5% high-cost beneficiaries in the Netherlands.DesignCross-sectional study using 1 year claims data. We broke down high-cost beneficiaries by demographics, the most cost-incurring condition per beneficiary and expensive treatment use.SettingDutch curative health system, a health system with universal coverage.Participants4.5 million beneficiaries of one health insurer.MeasuresAnnual total costs through hospital, intensive care unit use, expensive drugs, other pharmaceuticals, mental care and others; demographics; most cost-incurring and secondary conditions; inpatient stay; number of morbidities; costs per ICD10-chapter (International Statistical Classification of Diseases, 10th revision); and expensive treatment use (including dialysis, transplant surgery, expensive drugs, intensive care unit and diagnosis-related groups >€30 000).ResultsThe top 1% and top 2%-5% beneficiaries accounted for 23% and 26% of total expenditures, respectively. Among top 1% beneficiaries, hospital care represented 76% of spending, of which, respectively, 9.0% and 9.1% were spent on expensive drugs and ICU care. We found that 54% of top 1% beneficiaries were aged 65 years or younger and that average costs sharply decreased with higher age within the top 1% group. Expensive treatments contributed to high costs in one-third of top 1% beneficiaries and in less than 10% of top 2%-5% beneficiaries. The average number of conditions was 5.5 and 4.0 for top 1% and top 2%-5% beneficiaries, respectively. 53% of top 1% beneficiaries were treated for circulatory disorders but for only 22% of top 1% beneficiaries this was their most cost-incurring condition.ConclusionsExpensive treatments, most cost-incurring condition and age proved to be informative variables for studying this heterogeneous population. Expensive treatments play a substantial role in high-costs beneficiaries. Interventions need to be aimed at beneficiaries of all ages; a sole focus on the elderly would leave many high-cost beneficiaries unaddressed. Tailored interventions are needed to meet the needs of high-cost beneficiaries and to avoid waste of scarce resources.
