Abstract

BACKGROUND & AIMS: Despite rapidly increasing NAFLD prevalence, providers' knowledge may be limited. We assessed NAFLD knowledge and associated factors among physicians of different specialties globally.

APPROACH & RESULTS: NAFLD knowledge surveys containing 54 and 59 questions covering three 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 (GBD) super-regions. Over 24 months, 2202 surveys were completed (488 hepatologists, 758 GEs, 148 ENDOs, and 808 PCPs; 50% High-Income GBD super-region, 27% from North Africa and Middle East, 12% Southeast Asia, and 5% South Asian and Latin America). Hepatologists saw the greatest number of NAFLD patients annually: median (IQR) 150 (60-300) vs. 100 (35-200) for GEs, 100 (30-200) for ENDOs, and 10 (4-50) for PCPs (all p<0.0001). The primary sources of NAFLD knowledge acquisition for hepatologists were international conferences (33% vs. 8-26%) and practice guidelines for others (39-44%). Internet was the second most common source of NAFLD knowledge for PCPs (28%). NAFLD knowledge scores were higher for hepatologists than GEs: Epidemiology 62% vs. 53%, Diagnostics 80% vs. 73%, Treatment 61% vs. 58% (p<0.0001) and ENDOs scores were higher than PCPs: Epidemiology 70% vs. 60%, Diagnostics 71% vs. 64%, Treatment 79% vs. 68% (p<0.0001). Being a hepatologist or ENDO was associated with higher knowledge scores than GE or PCP, respectively (p<0.05). Higher NAFLD knowledge scores were independently associated with greater number of NAFLD patients seen (p<0.05).

CONCLUSION: Despite the growing burden of NAFLD, significant knowledge gap remains for identification, diagnosis and management of NAFLD.
