Report published in the International Journal of COPD concludes that COPD diagnoses obtained from electronic health records in China are of good quality and suitable for large population-based studies and do not warrant systematic adjudication of all the reported cases.

Chronic Obstructive Pulmonary Disorder (COPD) is the fourth leading cause of death worldwide, with particularly high rates in the People’s Republic of China, even among never smokers. Large population-based cohort studies should allow for reliable assessment of the determinants of diseases, which is dependent on the quality of disease diagnoses. During 7 years of follow-up of the CKB cohort, 11,800 COPD cases were identified by linkage with mortality registries and the national health insurance system. We randomly selected ~10% of the reported COPD cases and then undertook an independent adjudication of retrieved hospital medical records in 1,069 cases in order to assess the validity of COPD diagnoses.
