Proactive Liver Disease Assessment and Brief Intervention Among Hospitalized People With Harmful Alcohol Consumption: An Investigator-initiated, Pragmatic, Parallel-group, Open-label, 2-arm Randomized Controlled Trial to Investigate the Efficacy of Proactive Elastography-based Brief Alcohol Intervention Compared With Usual Care in Hospitalized Adult Participants at Risk of Alcohol-related Liver Disease

Harmful alcohol consumption constitutes a major contributor to global morbidity, being associated with many diseases and injury outcomes; it is the leading cause of liver cirrhosis and represents a significant cause of hospital admissions. Alcohol-related liver disease (ALD) is characterized by slow progression from a healthy liver to steatohepatitis, progressive fibrosis, cirrhosis, and life-threatening liver decompensation. The risk of progression is related to the volume and pattern of drinking. Because disease progression is usually asymptomatic with subtle biochemical or imaging abnormalities, liver disease may remain undiagnosed for decades and often present with end-stage complications at a point where survival is poor. At all stages of ALD, substantial reversibility and improved prognosis can be achieved if alcohol intake is stopped or reduced.

Brief alcohol intervention (BAI) is a time-limited structured motivational intervention targeting harmful alcohol use. Meta-analyses have shown that BAI can lead to modest but clinically meaningful reductions in alcohol intake, alcohol-related harm and mortality in primary care and hospital settings.

Elastography is an ultrasound-based technique that provides liver stiffness measurements (LSM) as a surrogate marker of liver fibrosis and portal hypertension. A unique feature of elastography is that it provides immediate disease staging following a quick bedside examination with ample opportunities for biofeedback, tailored BAI, and linkage to further hepatology and addiction care as needed. There is increasing evidence that such personalized healthcare communications involving biofeedback based on markers of liver injury may have more impact on drinking behavior than BAI alone.

There is an unmet need for interventions to promote case-finding, timely liver fibrosis detection, and reduction of alcohol-related harms among people at risk of ALD. Hospitalization presents a unique opportunity for intervention, as patients may be more receptive to behavioral change during acute illness. Hospital admission may therefore represent a 'teachable moment' that may enhance intervention impact.

This study will investigate the efficacy of proactive elastography-based liver disease assessment and structured counseling according to BAI principles in emergency hospitalized individuals at risk of ALD. The hypothesis is that proactive assessment of liver health during hospitalization may motivate reductions in alcohol use and thereby prevent disease complications and recurrent admissions more effectively than usual care.
