This is a pilot study examining whether an evidence-based recovery support smartphone application, the Addiction Comprehensive Health Enhancement Support System (A-CHESS), can decrease alcohol recidivism in a previously unstudied group of patients with alcoholic liver disease (ALD).

A-CHESS is a smartphone application developed by the University of Wisconsin-Madison based on self-determination theory, with a previous randomized clinical trial showing that use of the app resulted in significantly fewer risky drinking days in patients leaving treatment for alcohol-use disorders. The application is downloaded to the participant's smartphone, and provides ongoing access to peer support and educational materials, monitoring of the risk of relapse, and delivery of reminders and encouragements to the patient. The application also has a survey platform to assess and reassess the participants' most recent alcohol consumption, quality of life, and experience using the application. We anticipate that use of the A-CHESS app will result in decreased drinking and improved abstinence, identifying a potential intervention to offer patients with ALD to improve their mortality, liver disease, and likelihood of liver transplant candidacy status.
