Elastography-based Brief Alcohol Intervention in Hospitalized Individuals (PREDILECTION)

2026年6月4日 更新者：Håvard Midgard、Oslo University Hospital

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 use is a common cause of hospital admissions and the leading cause of liver cirrhosis. Timely detection of liver disease is crucial to prevent liver disease progression and reduce alcohol-related harms. 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. The study will recruit 500 patients at risk of alcohol-related liver disease who are admitted for inpatient care for any reason. Recruitment will be done at 8 Norwegian hospitals over an 18-month period. Participants will be randomized to liver elastography (liver stiffness measurement) and personalized alcohol counselling, or to usual care. After discharge, participants will be followed with study visits after 3, 6 and 12 months. Assessments during follow-up include self-reported alcohol use, the alcohol biomarker PEth and health-related quality of life. The primary outcome is the number of emergency hospital admissions for any reason within 2 years, collected from the Norwegian Patient Registry. The study has very low risk for the participants, with no invasive procedures or risks associated with the intervention. The potential benefit is considerably greater, with opportunities for improved health, prognosis, and quality of life for a large patient group for whom effective interventions are largely lacking.

详细说明

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.

This is a Norweigan multicenter study that will include patients at risk of ALD admitted for inpatient care for any reason. Approximately 500 patients will be included from 8 hospitals over a period of 18 months. Patients will be screened for harmful alcohol use (AUDIT-C) and for liver fibrosis (FIB-4) during admission/hospitalization, and will be assigned 1:1 to recieve elastography-based BAI in addition to usual care, or usual care alone, according to standard clinical practice.

Elastography-based BAI will be delivered during hospitalization. After discharge, patients will be followed up with study visits after 3, 6 and 12 months. Assessment during follow-up includes questionnaires on health related quality of life, alcohol consumption and effects of alcohol, clinical investigation, and blood test including the alcohol biomarker PEth. Long-term follow up are registry data extraction after 2, 5 and 10 years.

The primary objective is to demonstrate whether elastography-based BAI is superior to usual care in reducing hospital admissions for any reason within 2 years. Key secondary objectives are to demonstrate whether elastography-based BAI is superior to usual care in reduce harmful alcohol consumption as measured by PEth, AUDIT and weekly alcohol units. The study also aims to evaluate cost-effectiveness of the intervention, health-related quality of life, self-reported alcohol effects, prognostic serum biomarkers, candidate genetic polymorphisms, and metabolomics.

参与者组/臂
干预/治疗
无干预：Usual care
Participants randomized to the usual care arm will recieve standard clinical care as provided during routine hospital practice for inpatients with signs of harmful alcohol use.
有源比较器：Elastography-based brief alcohol intervention
Participants randomized to the elastography-based brief alcohol intervention groupe, will, in addition to usual care, recieve liver stifness measurements (LSM) and brief alcohol intervention.
行为的：Elastography-based brief alcohol intervention
Participants randomized to elastography-based BAI will receive elastography assessment during first hospitalization. Elastography is a widely validated ultrasound-based technique that measures liver stiffness as a surrogate marker of liver fibrosis. The BAI will be delivered according to the FRAMES model, a structured, evidence-based framework for brief motivational interventions targeting harmful alcohol use. The intervention is patient-centered, non-confrontational, and based on principles of motivational interviewing. Both the elastography and the BAI will last approximately 10-15 minutes and will be delivered by trained study personnel directly following elastography assessment. At 3 months, participants will receive BAI by telephone. Follow-up reinforcement of elastography-based BAI will subsequently be provided during scheduled visits at 6 and 12 months.
