Chart Validation of Inpatient ICD-9-CM Administrative Diagnosis Codes for Venous Thromboembolism among Intravenous Immune Globulin Users in the Sentinel Distributed Database

The Sentinel Distributed Database (SDD) is a database of patient administrative healthcare records, derived from insurance claims and electronic health records, sponsored by the US Food and Drug Administration for evaluation of medical product outcomes. There is limited information on the validity of diagnosis codes for acute VTE in the SDD and administrative healthcare data more generally. This paper describes the results of a chart validation study of potential cases of acute VTE ascertained from the SDD.
