![]() Although there are some epidemiological studies on T1D patients in Japan, studies on T1D using health insurance claims data are scarce. T1D patients need to regularly self-monitor their plasma glucose level and self-inject insulin for all their life, and have a higher risk of developing cardiovascular diseases than the general population. Type 1 diabetes (T1D) is a chronic disease caused by the destruction of insulin-producing beta cells of the pancreas. We have established a case definition with high PPV, and the case definition can be used for precisely detecting T1D patients from claims data in Japan. By using the case definition of both the confirmed diagnosis of T1D and either of the claims code of the two insulin treatment methods (i.e., syringe pump for CSII and insulin needles), PPV improved to 90.2 (95% CI: 85.2, 94.4). ResultsĪs a result of performance evaluation, the sensitivity of the confirmed disease name of T1D was 32.9 (95% CI: 28.4, 37.2), and positive predictive value (PPV) was 33.3 (95% CI: 38.0, 38.4). The predictive model was applied to patients of test group (validation data), and performances of candidate case definitions were evaluated. We constructed a predictive model for T1D patients using disease names, medical practices, and medications as explanatory variables. (ICD 10) code of T1D, the claims code of insulin needles for T1D patients, basal insulin, and syringe pump for continuous subcutaneous insulin infusion (CSII). As the candidate case definitions for claims data, we constructed 11 definitions by combinations of International Statistical Classification of Diseases and Related Health Problems, Tenth Revision. The EHR and claims data for all the visiting patients in a University Hospital were used. This study aimed to evaluate the performance of candidate case definitions for T1D using Electronic health care records (EHR) and claims data in a University Hospital in Japan.
