Key result
Current NAFLD guidelines drive ~77% specialist referrals in T2D, showing poor discrimination vs simpler algorithms.
Why the study?
Patients with type 2 diabetes are at risk for non-alcoholic fatty liver disease and associated complications, but the performance of international and national risk stratification guidelines needed evaluation.
How do current international and national guidelines perform for NAFLD risk stratification and specialist referral in patients with type 2 diabetes?

How do current international and national guidelines perform for NAFLD risk stratification and specialist referral in patients with type 2 diabetes?
Current NAFLD guidelines result in very high specialist referral rates for patients with T2D, whereas simplified algorithms or the FAST score may provide comparable diagnostic performance with a lower referral burden.
Guideline-based NAFLD stratification in T2D yields variable referral rates; leaves open optimal thresholds pending outcome validation.
Patients with type 2 diabetes (T2D) are at risk for non-alcoholic fatty liver disease (NAFLD) and associated complications. This study evaluated the performance of international (EASL-EASD-EASO) and national (DGVS) guidelines for NAFLD risk stratification. Patients with T2D prospectively underwent ultrasound, liver stiffness measurement (LSM) and serum-based fibrosis markers. Guideline-based risk classification and referral rates for different screening approaches were compared and the diagnostic properties of simplified algorithms, genetic markers and a new NASH surrogate (FAST score) were evaluated. NAFLD risk was present in 184 of 204 screened patients (age 64.2 ± 10.7 years; BMI 32.6 ± 7.6 kg/m2). EASL-EASD-EASO recommended specialist referral for 60–77% depending on the fibrosis score used, only 6% were classified as low risk. The DGVS algorithm required LSM for 76%; 25% were referred for specialised care. The sensitivities of the diagnostic pathways were 47–96%. A simplified referral strategy revealed a sensitivity/specificity of 46/88% for fibrosis risk. Application of the FAST score reduced the referral rate to 35%. This study (a) underlines the high prevalence of fibrosis risk in T2D, (b) demonstrates very high referral rates for in-depth hepatological work-up, and (c) indicates that simpler referral algorithms may produce comparably good results and could facilitate NAFLD screening.

Blank et al. (2020) conducted a cross-sectional in Type 2 diabetes at risk for non-alcoholic fatty liver disease (NAFLD) (n=184). Guideline-based NAFLD risk stratification (EASL-EASD-EASO and DGVS) vs. Simplified referral algorithms (e.g., AST > ULN) was evaluated on Specialist referral rate and diagnostic sensitivity for fibrosis risk. Current international (EASL-EASD-EASO) and national (DGVS) NAFLD guidelines resulted in high specialist referral rates of 60-77% in patients with type 2 diabetes, demonstrating poor diagnostic discrimination compared to simpler algorithms.
