Abstract Aims The paucity of data on Type 1 diabetes in China hinders progress in care and policy-making. This study compares Type 1 diabetes care and clinical outcomes in Beijing and Shantou with current clinical guidelines. Methods The 3C Study was a cross-sectional study of the clinical practices and outcomes of people with Type 1 diabetes. The study sequentially enrolled 849 participants from hospital records, inpatient wards, and outpatient clinics. Data were collected via face-to-face interviews with patients and health professionals, the Summary of Diabetes Self-Care Activities, medical records, and venous blood samples. Care was audited using ISPAD/IDF indicators. Data underwent descriptive analysis and tests for association. Results The median age was 22 years (IQR=13–34 years), and 48·4% of the sample had diabetes less than six years. The median HbA1c was 8·5% (69 mmol/mol) (IQR 7·2%–10·5%), with significant regional variance (p= 0·002). Insulin treatment was predominantly two injections/day (45% of patients). The highest incidence of diabetic ketoacidosis was 14·4 events/100 patient years among adolescents. Of the 57·3% of patients with LDL-C >2·6 mmol/L, only 11·2% received treatment. Of the 10·6% considered hypertensive, 47·1% received treatment. Rates of documented screening for retinopathy, nephropathy, and peripheral neuropathy were 35·2%, 42·3%, and 25·0%, respectively. The median number of days of self-monitoring/week was 3·0 (IQR=1·0–7·0). There were significant differences in care practices across regions. Conclusions The study documented an overall deficit in care with significant regional differences noted compared to practice guidelines. Modifications to treatment modalities and the structure of care may improve outcomes.
