Objective: To provide an overview of the incidence of certain diabetes-related complications in France in 2013: myocardial infarction, stroke, foot ulcers, lower limb amputation, initiation of renal replacement therapy for end-stage chronic kidney disease (ESCD), as well as adherence to recommended follow-up tests. Methods: The analyses are based on data from the National Inter-Regime Health Insurance Information System (Sniiram), linked to the Medical Information Systems Program (PMSI) and the Epidemiological and Nephrology Information Network (REIN) registry. The incidence of complications and the frequency of follow-up for recommended tests were broken down by sex, age, region, eligibility for the Universal Health Coverage Supplement, and quintiles of a territorial index of social disadvantage. The analyses focus on the diabetic population receiving pharmacological treatment and, for ESRD, on the diabetic population defined according to clinical criteria. Results: In 2013, in France, among the 3 million people receiving pharmacological treatment for diabetes, 11,737 were hospitalized for a myocardial infarction (2.2 times more than in the non-diabetic population), 17,148 for a stroke (1.6 times more), 20,493 for a foot ulcer (5 times more), 7,749 for a lower limb amputation (7 times more), and 4,256 began renal replacement therapy for end-stage renal disease (9 times more). Men were more affected than women by all complications. Despite the small socioeconomic disparities observed in the recommended biological monitoring, disparities were high in the occurrence of complications. Clinical monitoring remained more frequent among the most affluent individuals. Regional disparities were significant, with complication incidence rates markedly higher in the overseas departments and certain metropolitan regions, notably Nord-Pas-de-Calais. Conclusion: Even though these figures are underestimated, as they are based solely on individuals receiving pharmacological treatment, this assessment of complications serves as a reminder of the severity of diabetes. These complications, which are preventable, remain common and exacerbate the social and regional inequalities associated with the onset of diabetes.
