Cash for clean blood: new trial offers money to help liver patients quit alcohol

This study tests whether giving financial rewards based on a blood test can help people with alcohol-related liver disease stop or reduce drinking. The blood test detects alcohol use over the past month. 90 adults will be randomly assigned to either a rewards group that gets escalating payments for reduced drinking or a monitoring group that gets fixed payments. The goal is to see if the rewards program improves abstinence and reduces alcohol use over 12 and 24 weeks.
