The purpose of the present study was to compare the basic glycemic control parameters—HbA1c, CV%, and hypoglycemia, as well as quality of life and depression score in patients with type 1 diabetes using continuous subcutaneous insulin infusion (CSII) versus multiple daily injections (MDI). 324 adult patients with type 1 diabetes—146 using CSII and 178 on MDI, were enrolled in this cross-sectional study. HbA1c was assessed in whole blood by immuno-turbidimetric NGSP certified method. CV% was derived from CGM or was calculated from a 9-point capillary blood glucose profile. Hypoglycemia frequency, severity, and awareness were assessed using Clarke’s hypoglycemia questionnaire. Quality of life (QOL) was assessed using a questionnaire by the Psychiatric Research Unit and the CES-D scale. CSII group compared to MDI group showed significantly lower HbA1c—7.3% (6.6–8.0%) vs 8.2% (7.2–9.6%) (p
