Purpose No prior studies have addressed the performance of electronic health record (EHR) data to diagnose chronic obstructive pulmonary disease (COPD) in people living with HIV (PLWH), in whom COPD could be more likely to be underdiagnosed or misdiagnosed, given the higher frequency of respiratory symptoms and smoking compared with HIV‐uninfected (uninfected) persons. Methods We determined whether EHR data could improve accuracy of ICD‐9 codes to define COPD when compared with spirometry in PLWH vs uninfected, and quantified level of discrimination using the area under the receiver‐operating curve (AUC). The development cohort consisted of 350 participants who completed research spirometry in the Examinations of HIV Associated Lung Emphysema (EXHALE) study, a pulmonary substudy of the Veterans Aging Cohort Study. Results were externally validated in 294 PLWH who performed spirometry for clinical indications from the University of Washington (UW) site of the Centers for AIDS Research Network of Integrated Clinical Systems cohort. Results ICD‐9 codes performed similarly by HIV status, but alone were poor at discriminating cases from non‐cases of COPD when compared with spirometry (AUC 0.633 in EXHALE; 0.651 in the UW cohort). However, algorithms that combined ICD‐9 codes with other clinical variables available in the EHR—age, smoking, and COPD inhalers—improved discrimination and performed similarly in EXHALE (AUC 0.771) and UW (AUC 0.734). Conclusions These data support that EHR data in combination with ICD‐9 codes have moderately good accuracy to identify COPD when spirometry data are not available, and perform similarly in PLWH and uninfected individuals.
