Alcohol contributes to over 5% of deaths worldwide, and UK death rates from alcohol-related liver disease (ARLD) are rising. Ongoing alcohol use in ARLD leads to markedly increased mortality, however there are no effective pharmacological therapies for maintaining abstinence. Behaviour change interventions (BCIs) are effective psychological tools for reducing alcohol use, but are difficult to scale.
This project developed a smartphone app and breathalyser (AlcoChange), to:
AlcoChange was developed following feedback from alcohol service users. It allows monitoring of craving, alcohol consumption and breath alcohol, and provides motivational messaging in response to patient triggers.
The pilot study recruited inpatients/outpatients at the Trust with ARLD and recent alcohol use. Inclusion criteria were intent to maintain abstinence, and possession of a compatible phone. Exclusion criteria were Child-Pugh score >7, or inability to provide consent. The primary endpoint was self-reported alcohol use.
