Alcohol relapse after liver transplant ranges from 4% to as high as 95% among patients with alcoholic liver disease (ALD) and better tools are needed to identify those at increased risk, Jiten P. Kothadia, MD, of the University of Tennessee Health Science Center, Memphis, said in a presentation given in October at the annual meeting of the American College of Gastroenterology.
Dr. Kothadia and colleagues evaluated the effectiveness of the Social Determinant Acuity Tool (S-DAT), which stratified patients in terms of successful post-liver transplant outcomes from excellent (S-DAT scores 0-6) to poor candidates (scores 35-40). The S-DAT categories included cognitive function, mental health, social support, coping skills, financial status, compliance, alcohol abuse, substance abuse, reliability, legal issues, understanding the transplant process, and desire for transplant.
The study population included 140 adults with alcoholic liver disease who underwent a liver transplant between January 2016 and November 2021 at a single center. Before surgery, all patients underwent a thorough psychosocial evaluation using the S-DAT. The mean age of the participants was 53.4 years, 107 were male, and 67.9% had abstained from alcohol for more than 6 months prior to transplant.
The primary outcome of post-liver transplant alcohol relapse was defined as any alcohol use regardless of the amount or frequency, based on patient interviews or blood or urine tests.
Overall, the rate of relapse was 23.6%; and the rate within a year was 18.6%. In a multivariate analysis, S-DAT score was a significant predictor of relapse (odds ratio [OR] 1.65, P = .000). Other independent predictors of relapse were post-LT alcohol treatment (OR 7.11, P = .02), smoking history (OR 0.15, P = .03), and marital status (OR 60.28, P = .000). The area under the receiver operative curves (AUROC) for the S-DAT score to predict alcohol relapse within 1 year after LT was 0.77.
The sensitivity of the S-DAT for predicting relapse risk was 96.2%, and specificity was 40.4%; positive and negative predictive values were 26.9% and 97.9%, respectively.
The high sensitivity and negative predictive values of the S-DAT make it a useful screening tool for identifying patients at low risk of alcohol relapse after a liver transplant, Dr. Kothadia said in an interview. “Our score will guide risk-based interventions post-LT to reduce post-LT relapse and improve long-term outcomes.”
The findings included only data from a single center, which may limit generalizability, Dr. Kothadia said. The tool is not yet clinically available, he noted.
“We would like to perform external validation of our S-DAT score as it stresses the importance of these psychosocial variables,” and to confirm the findings in larger, multicenter, prospective clinical trials, he said.
The study received no outside funding. Dr. Kothadia indicated no relevant financial relationships.
