Objective: To validate a set of indicators for quality of diabetes care through their relationship with measurable clinical outcomes. Design: A retrospective cohort study was carried out from 2010 to 2015. Setting: Population-based study. Data were retrieved from healthcare utilization databases of three Italian regions (Lombardy, Emilia Romagna and Lazio) on the whole covering 20 million citizens. Participants: The 77 285 individuals who were newly taken in care for diabetes during 2010 entered into the cohort. Interventions: Exposure to selected clinical recommendations (i.e. periodic controls for glycated hemoglobin, lipid profile, urine albumin excretion, serum creatinine and dilated eye exams) was recorded. Main outcomes measures: A composite outcome was employed taking into account hospitalizations for brief-term diabetes complications, uncontrolled diabetes, long-term vascular outcomes and no traumatic lower limb amputation. A multivariable proportional hazards model was fitted to estimate hazard ratio, and 95% confidence intervals (CI), for the exposure-outcome association. Results: Among the newly taken in care patients with diabetes, those who adhered to almost none (0 or 1), just some (2 or 3) or almost all (4 or 5) recommendations during the first year after diagnosis were 44%, 36% and 20%, respectively. Compared patients who adhered to almost none recommendation, significant risk reductions of 16% (95% CI, 6–24%) and 20% (7–28%) were observed for those who adhered to just some and almost all recommendations, respectively
