Validity of Hospital ICD-10-GM Codes to Identify Acute Liver Injury

Description

Liver toxicity is a rare but relevant side effect of drugs. This validation study was part of a multi-center EMA Pharmacovigilance Study (Past Authorization Safety Study (PASS): Liver toxicity of agomelatine). The PASS is based on large pharmacoepidemiological databases, including GePARD from BIPS. The safety outcome, acute liver injury (ALI) is identified based on pre-specified combinations of ICD codes.

In our validation study we examined the positive predictive value of hospital discharge code combinations to describe ALI. Verification procedures included extraction of liver enzyme values and clinical information from patient Charts, performed in cooperation with the University Hospital (Klinikum Oldenburg) in Oldenburg.

The results will facilitate the use of routine data in the context of pharmacoepidemiological studies on drug safety, including estimation of bias from outcome misclassification.
