Use of coded and administrative data to identify mental health conditions: impediments and implications in a chronic pain study.
We evaluated the accuracy of diagnostic codes for schizophrenia in identifying actual cases in the historical charts of 801 primary care patients. The rate of schizophrenia by diagnostic code was 14%, whereas the estimated rate based on independent clinical chart review by a trained psychiatrist, using DSM-IV criteria, was 1.8%. The findings suggest that coded data alone should not be used to determine which patients have schizophrenia for research studies.
