Chronic liver disease (CLD) is frequently diagnosed at a late stage when prognosis is poor. We aimed to determine the patient factors associated with a late CLD diagnosis and its subsequent impact on survival to support early diagnosis initiatives.
We identified participants of UK biobank (UKB) study who developed first-time advanced CLD within 5 years. We identified the factors associated with late diagnosis via logistic regression and used survival analysis to measure the association between late CLD diagnosis and mortality risk.
A total of 725 UKB participants developed first-time advanced CLD event within 5 years. In total, 83% of cases were diagnosed late. Late diagnosis was associated with aetiology; the odds of late diagnosis were 12 times higher for an individual with alcohol-related liver disease (ArLD) vs viral hepatitis (aOR:12.01; P < 0.001). Cumulative mortality 5 years after incident advanced CLD was 43.4% (95% CI:39.6-47.0). Late diagnosis was associated with a higher risk of postadvanced CLD mortality for patients with non-alcoholic fatty liver disease (aHR:2.18; 95% CI:0.86-5.51; P = 0.10), but not for other aetiologies.
Late CLD diagnosis varies according to aetiology and is highest for patients with ArLD and non-alcoholic fatty liver disease. The association between late diagnosis and postadvanced CLD mortality may also vary by aetiology.
