Background:
As metabolic dysfunction-associated steatotic liver disease (MASLD) management extends into primary care, little is known about patterns of specialty referral for affected patients. We determined the proportion of primary care patients with MASLD that received a gastroenterology (GI) consultation and compared advanced fibrosis risk between patients with and without a referral.
Methods:
This retrospective study of electronic health record data from a primary care clinic included patients with MASLD, no competing chronic liver disease diagnoses, and no history of cirrhosis. Referral to GI for evaluation and management (E/M) any time after MASLD ascertainment was the outcome. Fibrosis-4 Index (FIB-4) scores were calculated, categorized by advanced fibrosis risk, and compared by receipt of a GI E/M referral. Logistic regression models were developed to determine the association of FIB-4 risk with receipt of a GI referral.
Results:
The cohort included 652 patients of which 12% had FIB-4 scores (≥2.67) at high-risk for advanced fibrosis. Overall, 31% of cohort patients received a GI referral for E/M. There was no difference in the proportion of patients with high (12% vs. 12%, p=0.952) risk FIB-4 scores by receipt of a GI E/M referral. In adjusted logistic regression models, high-risk FIB-4 scores (OR 1.01; 95% CI 0.59 - 1.71) were not associated with receipt of a referral.
Conclusions:
Only 30% of patients in this primary care MASLD cohort received a GI E/M referral during the study period, and those patients with a referral did not differ by FIB-4 advanced fibrosis risk.

Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
