Liver fibrosis evaluation is mandatory in non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD) to decide the patient management. Patients with these diseases are usually under the care of non-liver specialists who refer them to specialized centers where the most accurate fibrosis tests are available. We aimed to evaluate whether simple blood fibrosis tests available to all physicians help to reduce the rate of unnecessary referral of NAFLD and ALD patients without advanced fibrosis.

NAFLD and/or ALD patients newly referred to our center for a non-invasive evaluation of liver fibrosis were retrospectively included. The FibroMeter^VCTE (FM^VCTE, combination of blood markers and Fibroscan results) was defined as the reference test for specialized evaluation of liver fibrosis. A FM^VCTE result <0.384 indicated the absence of advanced fibrosis and thus an “unnecessary referral”.

558 patients were included (NAFLD: 283, ALD: 156, mixed NAFLD+ALD: 119). FM^VCTE was <0.384 (unnecessary referral) in 58.8% of patients. FIB4 was <1.30 in 45.2% and eLIFT <8 in 47.7% of the patients. 84.9% of patients with FIB4 <1.30 and 85.3% of patients with eLIFT <8 had also FM^VCTE <0.384. Therefore, using FIB4 or eLIFT as first-line evaluation of liver fibrosis decreased by three-fold the rate of unnecessary referral. The negative predictive value of FIB4 and eLIFT was >80% whatever the underlying cause of chronic liver disease.

The use of eLIFT by non-liver specialists for NAFLD and ALD patients can improve the relevance of referrals for specialized evaluation of liver fibrosis.
