Factors Associated With Motivation to Reduce Alcohol Use Among Patients With Chronic Liver Disease

Alcohol use is prevalent among hepatology clinic patients with chronic liver disease (CLD). We explored factors associated with the importance and confidence dimensions of motivation to reduce drinking.

Participants (N = 121) with unhealthy alcohol use (i.e., over NIH guidelines) receiving care in hepatology clinics from a safety-net hospital (SN, N = 54) and two Veterans Affairs Healthcare Systems (VA, N = 67) were enrolled in an alcohol intervention trial from March 2022 through October 2023. Baseline assessments included Generalised Anxiety Disorder (GAD-7), Patient Health Questionnaire (PHQ-8), Alcohol Use Disorders Identification Test (AUDIT), COVID-19 stress; and measures of importance and confidence to decrease alcohol use (readiness rulers, scales of 1-10). Liver disease aetiology and severity were extracted from electronic health records. We performed multivariable linear regression models with forward selection to assess pre-specified variables' associations with importance and confidence.

The sample was 84% male, 40% Latino, 31% White, 18% Black and 11% other races; median age was 61 years. Median (Q1-Q3) AUDIT score was 16 (12-24), importance was 9 (6-10) and confidence was 8 (5-9). On multivariable analysis, VA site (vs. SN) participants had a 0.97-point lower importance score (p = 0.02); higher symptoms of depression (PHQ-8 score ≥ 10 vs. < 10) and AUDIT scores (for each point increase) were associated with higher importance score (estimates 1.2 and 0.08, p < 0.05, respectively). Liver disease aetiology and severity were not significantly associated with outcomes.

Depression, alcohol problem severity and treatment site may influence motivation to reduce alcohol use and could inform future hepatology-based interventions.
