Smoking cessation services are an established part of the UK health system, funded by national and local governments. Services are commissioned by Local Authorities (Local Government) according to local needs and are provided by organizations that are paid to deliver services, usually based on achieving a number of 4-week quits per year. Everyone Health is one such commissioned service, delivering Stop Smoking Services across England in 6 Local Authorities, and delivering thousands of 4-week quits per year. To maximize quit rates, Everyone Health has worked with Emeritus Professor Robert West of UCL and British Websites to develop an Artificial Intelligence-driven app to provide treats and advice to those being supported through our services to make and maintain a quit attempt. This oral presentation will describe the process of developing and initial piloting of the app and the plans for evaluation following the rollout.
