OBJECTIVE: Ethnic differences in outcomes of outpatient diabetic care and the role of self-management behavior and its determinants in explaining observed differences. METHODS: Face-to-face interviews were held with 102 Turkish or Moroccan, and 102 native Dutch diabetic patients to measure self-management behavior and determinants of self-management (as derived from the Attitudes-Social support self-Efficacy model, and Personal Models and Barriers). A medical record review was conducted to measure ethnic differences in outcomes of diabetes care. Data were analyzed using multiple linear regression. RESULTS: Outcomes differed significantly with ethnic minorities having higher levels of lipids (risk difference=RD=0.7%; CI: 0.3-1.2) and HbA1c (RD=0.9%; CI: 0.4-1.4) than native Dutch patients. Differences in self-management could not explain the ethnic differences in outcomes. Self-efficacy explained 18% of the ethnic differences in HbA1c. Beliefs about seriousness of diabetes and social support regarding diabetes management together explained 47% of the ethnic differences in lipids. CONCLUSION: This study provides evidence for ethnic differences in outcomes of diabetes care. Self-efficacy is the most important determinant in explaining the differences in HbA1c. PRACTICE IMPLICATIONS: For diabetes practice this suggests that strengthening patients' self-efficacy may improve the control of HbA1c and may result in a decrease of ethnic differences. The relationship between behavioral determinants like seriousness and social support and outcomes of diabetes care was differential by ethnic group, implying that caution is required when applying behavioral models to different ethnic groups.

Objective: To determine the influence of ethnic differences in diabetes care on inequalities in mortality and prevalence of end-stage complications among diabetic patients. The following questions were examined: 1) Are there ethnic differences among diabetic patients in mortality and end-stage complications and 2) are there ethnic differences among diabetic patients in quality of care?Research Design and Methods: A review of the literature on ethnic differences in the prevalence of complications and mortality among diabetic patients and in the quality of diabetes care was performed by systematically searching articles on Medline published from 1987 through October 2004.Results: A total of 51 studies were included, mainly conducted in the U.S. and the U.K. In general, after adjusting for confounders, diabetic patients from ethnic minorities had higher mortality rates and higher risk of diabetes complications. After additional adjustment for risk factors such as smoking, socioeconomic status, income, years of education, and BMI, in most instances ethnic differences disappear. Nevertheless, blacks and Hispanics in the U.S. and Asians in the U.K. have an increased risk of end-stage renal disease, and blacks and Hispanics in the U.S. have an increased risk of retinopathy. Intermediate outcomes of care were worse in blacks, and they were inclined to be worse in Hispanics. Likewise, ethnic differences in quality of care in the U.S. exist: process of care was worse in blacks.Conclusions: Given the fact that there are ethnic differences in diabetes care and that ethnic differences in some diabetes complications persist after adjustment for risk factors other than diabetes care, it seems the case that ethnic differences in diabetes care contribute to the more adverse disease outcomes of diabetic patients from some ethnic minority groups. Although no generalizations can be made for all ethnic groups in all regions for all kinds of complications, the results do implicate the importance of quality of care in striving for equal health outcomes among ethnic minorities.

Background: As in other Western countries, the number of immigrants in the Netherlands is growing rapidly. In 1980 non-western immigrants constituted about 3% of the population, in 1990 it was 6% and currently it is more than 10%. Nearly half of the migrant population lives in the four major cities. In the municipality of Rotterdam 34% of the inhabitants are migrants. Health policy is based on the ideal that all inhabitants should have equal access to health care and this requires an efficient planning of health care resources, like staff and required time per patient. The aim of this study is to examine ethnic differences in the use of internal medicine outpatient care, specifically to examine ethnic differences in the reason for referral and diagnosis., Methods: We conducted a study with an open cohort design. We registered the ethnicity, sex, age, referral reasons, diagnosis and living area of all new patients that visited the internal medicine outpatient clinic of the Erasmus Medical Centre in Rotterdam (Erasmus MC) for one year (March 2002-2003). Additionally, we coded referrals according to the International Classification of Primary Care (ICPC) and categorised diagnosis according to the Diagnosis Treatment Combination (DTC). We analysed data by using Poisson regression and logistic regression., Results: All ethnic minority groups (Surinam, Turkish, Moroccan, Antillean/Aruban and Cape Verdean immigrants) living in Rotterdam municipality, make significantly more use of the outpatient clinic than native Dutch people (relative risk versus native Dutch people was 1.83, 1.97, 1.79, 1.65 and 1.88, respectively). Immigrant patients are more likely to be referred for analysis and treatment of 'gastro-intestinal signs & symptoms' and were less often referred for 'indefinite, general signs'. Ethnic minorities were more frequently diagnosed with 'Liver diseases', and less often with 'Analysis without diagnosis'. The increased use of the outpatient facilities seems to be restricted to first-generation immigrants, and is mainly based on a higher risk of being referred with 'gastro-intestinal signs & symptoms'., Conclusion: These findings demonstrate substantial ethnic differences in the use of the outpatient care facilities. Ethnic differences may decrease in the future when the proportion of first-generation immigrants decreases. The increased use of outpatient health care seems to be related to ethnic background and the generation of the immigrants rather than to socio-economic status. Further study is needed to establish this.
