Around 80% of people experiencing homelessness smoke. E-cigarettes (ECs) are an effective quitting aid but have not been widely tested in this population. Project SCeTCH evaluates the offer of an EC or usual care (UC) to adult smokers accessing homeless centres, on smoking cessation, reduction, and risky smoking practices.
A multi-centre two-arm cluster randomised controlled trial (cRCT), including 32 homeless centres across Great Britain (480 participants). Randomisation includes either an EC with weekly allocations of e-liquid for 4-weeks or UC intervention comprising very brief advice and signposting to the local stop smoking service.
477 participants have been recruited and retention rates at 4- 12- and 24- weeks are currently 73%, 59% and 56% respectively. We have had to navigate a range of challenges in delivering the trial in this sector and will share these and the lessons learnt e.g., around recruiting centres and participants; working with multiple centres with different structures, provision, and individual needs; changing models of care and practice; and the role of incentives for all agencies.
This is the first cRCT to assign people experiencing homelessness to an EC and UC intervention to measure smoking abstinence and risky smoking practices. Running trials in this sector requires the need to understand the realistic needs of individuals and services, and to work pragmatically and flexibly and develop strong collaborative relationships with all agencies involved. Ultimately, if effective, the results will be used to inform the larger scale implementation of supporting homeless centres to aid smoking cessation programmes.
