A view on the quality of diabetes care in Italy and the role of Diabetes Clinics from the 2018 ARNO Diabetes Observatory.

BACKGROUNDS AND AIMS: To investigate relevant indicators of quality of care in a large population-based sample of people with diabetes representative of clinical practice in Italy in 2018. METHODS AND RESULTS: We analyzed data from 11,300,750 subjects. All administrative healthcare claims collected in 2018 were scrutinized to identify subjects with diabetes and investigate several indicators of quality of care. Subjects with diabetes were identified by anti-hyperglycemic drug prescriptions, disease-specific co-payment exemption and hospital discharge codes. Indicators of quality of care pertained to monitoring (HbA1c, creatinine, lipid profile, microalbuminuria, eye examination, ECG, ultrasonography of carotid and lower limb arteries) and diabetes treatment (anti-hyperglycemic agents in subjects with cardiovascular disease, CVD). Subjects attending and nonattending Diabetes Clinics were compared. We identified 697,208 individuals with diabetes. HbA1c was assessed at least once in the year in 62.7%, creatinine in 62.3%, total cholesterol in 59.6%, microalbuminuria in 34.3%. Frequency of eye examination was 8.2%, ECG 23.5%, carotid ultrasonography 14.3%, lower limb ultrasonography 7.6%. Among anti-hyperglycemic drugs, SGLT-2 inhibitors were prescribed to ~5% and GLP-1 receptor agonists to ~5% although the proportion of subjects with CVD was ~45%. Subjects attending Diabetes Clinics had higher figures for all these monitoring and treatment indicators. CONCLUSIONS: The implementation of national and international guidelines regarding disease monitoring and treatment is far from being satisfactory, especially among subjects nonattending Diabetes Clinics. Further efforts and investments are needed for better disseminating guidelines, more efficaciously engaging healthcare professionals and more strongly empowering the healthcare system to improve diabetes care.
