Outline of Final Research Achievements

The aim of this study is to evaluate the association between diabetes (DM) treatment and medical costs. First, we evaluated the validity of self-reported questionnaire on DM medication. Sensitivity and Specificity were 82.6% and 98.5%, respectively. Next, we compared medical costs between the subjects who suspected to be DM but not receive medication (DM patients without medication) and who received medication for DM (DM patients with medication). Total and outpatient medical costs were significantly higher in DM patients with medication than those without. On the other hand, there were no significant difference in inpatient medical costs between two groups. Our results did not support the evidence that DM treatment contribute to decrease medical costs in patients who suspected to be DM.
