Electronic Health Record Based Algorithm to Identify Patients with Autism Spectrum Disorder. PloS one. 11(11). e0159621. PMID: 27472449 [PubMed] PMCID: PMC4966969
Cohort selection is challenging for large-scale electronic health record (EHR) analyses, as International Classification of Diseases 9th edition (ICD-9) diagnostic codes are notoriously unreliable disease predictors. Our objective was to develop, evaluate, and validate an automated algorithm for determining an Autism Spectrum Disorder (ASD) patient cohort from EHR. We demonstrate its utility via the largest investigation to date of the co-occurrence patterns of medical comorbidities in ASD.
