Abstract
AIMS: To assess whereas prevalence, treatment and direct costs of drug-treated diabetes were similar in migrants and in people of Italian citizenship under the universalistic Italian health care system. METHODS AND RESULTS: Drug-treated diabetic individuals were identified in the population-based multiregional ARNO Observatory on the basis of 2010 prescriptions. Migrants were identified by the country-of-birth code on the fiscal identification code. Diabetes prevalence was calculated for Italians (n = 7,328,383) and migrants (n = 527,965). To assess the odds of migrants of having diabetes compared to Italians, we individually matched all migrants to Italians for major confounders (age, sex and place of residence). Finally, all migrants with diabetes were individually matched for confounders to Italians with diabetes to compare prescriptions, hospitalization rates, services use and direct costs for the National Health System. We identified 368,797 subjects with diabetes among Italians and 10,336 among migrants, giving prevalence of 5.03% and 1.96%, respectively. Migrants with diabetes were younger than Italians (52 ± 13 years vs. 68 ± 14 years, P < 0.001); after matching, their risk of disease was higher (odds ratio, 1.55, 95% confidence interval, 1.50-1.60). The total cost was 27% lower in migrants, due to lower cost of drugs (-29%), hospital admission (-27%) and health services (-22%). The number of packages/treated person-year of all glucose-lowering drugs was also lower in migrants (-15%) (P < 0.001). CONCLUSIONS: Compared to subjects of Italian ancestry, migrants to Italy show a higher risk of diabetes but less intense treatment. Inequalities in health care use are likely and are maintained also in a universalistic system.
