Subjective unmet need and utilization of health care services in Canada: what are the equity implications?

This study aimed to evaluate whether subjective assessments of unmet need may complement conventional methods of measuring socioeconomic inequity in health care utilization. This study draws on the 2003 Canadian Community Health Survey to develop a conceptual framework for understanding how unmet need arises, to empirically assess the association between utilization and the different types of unmet need (due to waiting times, barriers and personal reasons), and to investigate the effect of adjusting for unmet need on estimates of income-related inequity. The studys findings suggest that a disaggregated approach to analyzing unmet need is required, since the three different subgroups of unmet need that we identify in Canada have different associations with utilization, along with different equity implications. People who report unmet need due to waiting times use more health services than would be expected based on their observable characteristics. However, there is no consistent pattern of utilization among people who report unmet need due to access barriers, or for reasons related to personal choice. Estimates of inequity remain unchanged when we incorporate information on unmet need in the analysis. Subjective assessments of unmet need, namely those that relate to barriers to access, provide additional policy-relevant information that can be used to complement conventional methods of measuring inequity, to better understand inequity, and to guide policy action.

Diabetes and urbanization in the Omani population: an analysis of national survey data

BackgroundThe prevalence of type 2 diabetes in Oman is high and appears to be rising. Rising rates of diabetes and associated risk factors have been observed in populations undergoing epidemiological transition and urbanization. A previous study in Oman indicated that urban-dwellers were not significantly more likely to have diabetes. This study was undertaken to determine if a more accurate urban and rural categorization would reveal different findings.MethodsThis study included 7179 individuals aged 20 years or above who participated in a cross-sectional interviewer-administered survey in Oman including blood and anthropomorphic tests. Multiple logistic regression analyses were conducted to analyze the factors associated with diabetes, first in the whole population and then stratified according to region.ResultsThe prevalence of diabetes (fasting blood glucose ≥ 7 mmol/l) in the capital region of Muscat was 17.7% compared to 10.5% in rural areas. The prevalence of self-reported diabetes was 4.3%. Urban residence was significantly associated with diabetes (adjusted odds ratio (OR) = 1.7, 95% confidence interval (CI): 1.4–2.1), as was age (OR = 1.2, 95% CI: 1.1- 1.2), obesity (abnormal waist circumference) (OR = 1.8, 95% CI: 1.5–2.1), and systolic blood pressure (SBP) 120–139 (OR = 1.4, 95% CI:1.04–1.8), SBP 140–159 (OR = 1.9, 95% CI: 1.4–2.6), SBP ≥ 160 (OR = 1.7, 95% CI: 1.2–2.5). Stratified analyses revealed higher education was associated with reduced likelihood of diabetes in rural areas (OR = 0.6, 95% CI: 0.4–0.9).ConclusionA high prevalence of diabetes, obesity, hypertension and high cholesterol exist in the Omani population, particularly among urban-dwellers and older individuals. It is vital to continue monitoring chronic disease in Oman and to direct public health policy towards preventing an epidemic.

Inequity in publicly funded physician care: what is the role of private prescription drug insurance?

This study examines the impact that private financing of prescription drugs in Canada has on equity in the utilization of publicly financed physician services. The complementary nature of prescription drugs and physician service use alongside the reliance on private finance for drugs may induce an income gradient in the use of physicians. We use established econometric methods based on concentration curves to measure equity in physician utilization and its contributors in the province of Ontario. We find that individuals with prescription drug insurance make more physician visits than do those without insurance, and the effect on utilization is stronger for the likelihood of a visit than the conditional number of visits, and stronger for individuals with at least one chronic condition than those with no conditions. Results of the equity analyses reveal that the most important contributors to the pro-rich inequity in physician utilization are income and private prescription drug insurance, while public insurance, which covers older people and those on social assistance, has a pro-poor effect. These findings highlight that inequity in access to and use of publicly funded services may arise from the interaction with privately financed health services that are complements to the use of public services.

Equity in health care use among older people in the UK: an analysis of panel data

This article uses panel data to investigate the extent of income-related inequity in the likelihood of visiting a General Practitioner (GP), specialist, dentist and hospital among individuals aged 65 years and over in the UK. The probability of accessing health care is predicted with separate random effects probit panel models using data from the British Household Panel Survey (BHPS) for the period 1998 to 2006. We use well-established methods based on the concept of the concentration curve to compare the cumulative distribution of health care utilization with the cumulative distribution of the population ranked by income. The results find evidence for inequity in specialist and dental care, but only slight inequity for GP care and not significant inequity in hospital admissions. Levels of inequity are highest for specialist and dental care, even when users of the private sector are excluded from analyses. The Mobility Index (MI) is also used to compare short- and long-run estimates of inequities and show that upwardly income mobile individuals contribute to inequity in the long run.
