    Abstract: Background: Taiwan ’ s National Health Insurance Research Database (NHIRD) is one of the largest available claims database; however, the validity of the claims records in the NHIRD is still under investigation. Objectives: To evaluate the validity of claims records for clinical diagnoses, medication use, and health system utilization in the National Health Insurance Research Database (NHIRD). Methods: Design: The 2005 Taiwan National Health Interview Survey (NHIS), which is a nationwide cross-sectional survey investigating the health status of non-institutionalized residents in Taiwan Setting: A total of 15,574 participants aged 12 and above and consented to linkage with the data of Taiwan ’ s NHIRD for research purposes were enrolled. Main outcome measures: The self-reports in clinical diagnoses, medication use, and health system utilization were used to validate the accuracy of claims records in the in the NHIRD. Statistic analysis: We used Cohen ’ s kappa statistics and prevalence-adjusted bias-adjusted kappa to examine the concordance between claims records and patient self-reports. In addition, we used the self-report as the reference standard to test the sensitivity, specifi city, positive predictive value, and negative predictive value of claims records.Results: We found the overall concordance of the kappa statistics was moderate for clinical diagnosis and substantial for medication use and health system utilization. The prevalence-adjusted bias-adjusted kappa for all conditions was substantial to almost perfect. Using a strict algorithm to identify the clinical diagnoses of claims records could improve the prevalence-adjusted bias-adjusted kappa, specificity and positive predictive value. Conclusions: The concordance between the claims records and self-report survey results was moderate in clinical diagnoses, and substantial in medication use and health system utilization.
