Screening for alcohol-related liver disease (ALD) is recommended in individuals with alcohol use disorder (AUD). Our aim was to compare absolute risk estimates of ALD, cancer and cardiovascular disease (CVD) in individuals seeking treatment for AUD and the general population. We used nationwide healthcare registries to identify individuals in outpatient treatment for AUD and matched comparators from the general population (1:10) in Denmark and followed them for hospital diagnoses and cause-specific mortality 2006 to 2022. Analyses of cumulative incidence and cause-specific mortality used competing risk methodologies. Among 47,806 individuals seeking treatment for AUD, the median age was 46 years, 71% were men, 52% drank ≥ 20 units alcohol per week and 2.6% had type 2 diabetes. For individuals seeking treatment for AUD, the cumulative incidence of ALD after 10 years was 7.1% (95%CI: 6.9-7.4) overall, 13% in those with type 2 diabetes, much higher than the 10-year risk of 0.6% in the 477,850 age- and sex-matched comparators. The AUD cohort vs. comparators had a fourfold higher 10-year all-cause mortality risk of 17.8% vs. 4.5% with 10-year risk of death due to ALD of 2.1% vs. 0.2%. Half of the excess deaths among individuals seeking treatment for AUD were due to alcohol-related causes or external causes. Individuals in AUD treatment were two- to threefold more likely than comparators to die from cancer or CVD after 10 years despite a more similar disease incidence. This study showed the substantial burden of alcohol-related disease and mortality in individuals seeking treatment for AUD. Specifically, the risk of ALD was 7% after 10 years, 13% in those with type 2 diabetes. Knowledge of the absolute risk of alcohol-related liver disease (ALD) and cause-specific death among individuals in treatment for alcohol use disorder is crucial to make decisions on screening for ALD. The study highlights the need for improved care of individuals in treatment for alcohol-use disorder to prevent morbidity and mortality due to ALD, other alcohol-related causes, but also cancer and cardiovascular disease. The higher risk of ALD in those with type 2 diabetes suggests that clinicians should be specifically aware of alcohol consumption and liver disease in their patients with type 2 diabetes.
