Variance Between Clinical Guidance and Real-world Management of Metabolic Dysfunction-associated Steatotic Liver Disease in the United States.

Clinical practice guidelines can facilitate diagnosis and management of patients with metabolic dysfunction-associated steatotic liver disease and metabolic dysfunction associated steatohepatitis (MASH), although their implementation to date has been suboptimal. Using recently published 2023 American Association for the Study of Liver Diseases (AASLD) practice guidance-based recommendations as a reference, we assessed current real-world management of patients with MASH to identify gaps in clinical practice. We extracted data from the Adelphi Real World MASH Disease Specific Programme, a cross-sectional survey with retrospective data capture (from 85 hepatologists, gastroenterologists, and endocrinologists [Supplementary Table 1] and 633 patients [Supplementary Table 2] in the United States between January and June 2022). Two key goals of the AASLD guidance algorithm served as reference points: exclude fibrosis in low-prevalence populations (Goal A) and identify/manage people with 'at-risk' MASH or cirrhosis (Goal B). Patients were split into 2 groups: Goal A comprised 100 patients initially diagnosed by primary care physicians (PCPs)/endocrinologists, and Goal B included 533 patients managed by gastroenterologists/hepatologists.
