Identifying practice gaps to optimize medical care for patients with nonalcoholic fatty liver disease.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease. Primary care providers (PCPs), in contrast to gastroenterology/hepatology (GI/Hep) providers, are the first medical contact for the majority of patients with, or at risk for, NAFLD. PCP awareness of and facility with NAFLD is critical for management of these patients. AIM: The purpose of this study was to assess understanding and practice patterns of PCPs and non-GI/Hep subspecialty providers with respect to the diagnosis and management of NAFLD.
METHODS: We administered an online, 61-question survey to 479 providers in internal medicine, family medicine, endocrinology, cardiology, and obstetrics and gynecology (ObGyn) across three health systems: academic medical center, safety-net health system and managed care health system.
RESULTS: There were 246 respondents (51 %), with the majority (87 %) being PCPs (internal medicine, family medicine, ObGyn). Only 31 % of providers identified NAFLD as a clinically important diagnosis in their practice. Although 65 % of providers reported some degree of facility in diagnosing NAFLD, less than half (47 %) were comfortable managing NAFLD. Only 33 % refer patients with suspected NAFLD to GI/Hep. Subspecialists in endocrinology and cardiology reported greater clinical concern over NAFLD and were more likely (67 %) to refer patients with suspected NAFLD to GI/Hep.
CONCLUSIONS: The majority of providers do not identify NAFLD as a clinically important diagnosis and do not refer to GI/Hep. However, 83 % expressed a need for education on NAFLD. Our data reveal practice gaps within NAFLD care and identify opportunities for targeted education to guide PCPs in the evaluation and management of NAFLD.
