Using electronic medical record diagnostic codes to identify veterans with posttraumatic stress disorder

Researchers investigating posttraumatic stress disorder often use diagnostic codes embedded within electronic medical records to identify people with the disorder. We used data from a registry of veterans for whom both structured interview data and Veterans Health Administration EMR reports were available. We calculated diagnostic accuracy statistics for algorithms that demanded the presence of at least one and up to seven people in which a PTSD diagnosis was present in EMR data from any academic source, mental health clinic, or specialty PTSD clinic using interview-diagnosed PTSD as the reference criterion. Higher thresholds for the operationalization of PTSD may be justified in samples in which the PTSD prevalence is lower. Requiring three PTSD diagnoses from a mental health clinic or four diagnoses from any medical center could be a valid minimum benchmark for identifying patients with PTSD in EMRs; however, accuracy can be enhanced by requiring additional diagnoses.
