Introduction: Accurate assessment of alcohol use informs prevention and management of liver disease. We examined whether phosphatidylethanol (PEth, an alcohol metabolite) blood concentrations are associated with liver fibrosis risk independently of self-reported alcohol use, among persons with and without HIV.
Methods: We pooled individual-level data from 12 studies from the United States, Russia, Uganda, and South Africa with PEth, Alcohol Use Disorders Identification Test-Consumption (AUDIT-C), and fibrosis-4 (FIB-4) measurements.
Purpose: Accurate identification of hepatic decompensation is essential for pharmacoepidemiologic research among patients with chronic liver disease.
Methods: An algorithm using ≥ 1 inpatient or ≥ 2 outpatient International Classification of Diseases, 10th revision (ICD-10) codes for hepatic decompensation was developed in Veterans Health Administration data from October 2015 through July 2019. Medical records were reviewed by hepatologists to confirm cases.
