Abstract
To clarify the clinical characteristics of insulin-treated Type 2 diabetic (T2DM) patients, we analyzed data from 42 institutes in Japan using CoDiC®, an electronic system for diabetes data collection and management with 22,307 T2DM patients registered in 2006. We surveyed 5,795 treated with insulin for over 6 months. Those treated with insulin were diagnosed younger and had a shorter disease duration than those treated with oral hypoglycemic agents (OHA). Two injections of insulin per day was the most frequently prescribed treatment. Those administered prandial or basal bolus were diagnosed younger and had a shorter disease duration. Six months after treatment started, those with HbA1c of ≥8% were younger at diagnosis, had longer disease duration, and had higher BMI than those with HbA1c of ≤6.9%. These trends were more marked in those administered prandial or basal bolus. Our survey thus confirmed that insulin treatment is more likely to be prescribed in patients diagnosed younger and more severely affected by their disease. Even with insulin treatment, however, glycemic control was poor in those diagnosed younger, having longer disease duration, and with higher BMI.
