A Global Survey of Physicians Knowledge About Non-alcoholic Fatty Liver Disease.

Background & Aims Despite rapidly increasing nonalcoholic fatty liver disease (NAFLD) prevalence, providers’ knowledge may be limited. We assessed NAFLD knowledge and associated factors among physicians of different specialties globally. Methods NAFLD knowledge surveys containing 54 and 59 questions covering 3 domains (epidemiology/pathogenesis, diagnostics, and treatment) were completed electronically by hepatologists, gastroenterologists (GEs), endocrinologists (ENDOs), and primary care physicians (PCPs) from 40 countries comprising 5 Global Burden of Disease super-regions. Over 24 months, 2202 surveys were completed (488 hepatologists, 758 GEs, 148 ENDOs, and 808 PCPs; 50% high-income Global Burden of Disease super-region, 27% from North Africa and Middle East, 12% Southeast Asia, and 5% South Asian and Latin America). Results Hepatologists saw the greatest number of NAFLD patients annually: median 150 (interquartile range, 60–300) vs 100 (interquartile range, 35–200) for GEs, 100 (interquartile range, 30–200) for ENDOs, and 10 (interquartile range, 4–50) for PCPs (all P Conclusions Despite the growing burden of NAFLD, a significant knowledge gap remains for the identification, diagnosis, and management of NAFLD.
