This feasibility study evaluates the effectiveness of a household-based smoking cessation intervention for patients and their household members. Patients who smoke and live with household members who also smoke will be invited to participate in the Treating Tobacco Dependency (TTD) program at Royal Papworth Hospital. The study aims to assess whether providing support to both patients and their household members improves quit rates and reduces relapse risk.

Participants will receive nicotine replacement therapy (NRT) and behavioural support, with follow-up assessments at 28 days, 3 months, and 12 months after starting the program. This study will compare outcomes to historical data from patients who participated in the TTD program without household support.

The Treating Tobacco Dependency (TTD) program is currently available at Royal Papworth Hospital as part of an NHS initiative that started in August 2023. The program is available to all patients who smoke tobacco and are admitted to the hospital for at least 24 hours.

The TTD program provides NRT and behavioural counselling support, initially delivered by the TTD team at Royal Papworth Hospital, followed by HealthyYou, an NHS-approved stop smoking organization. Through this study, investigators are extending the invitation to household members of Royal Papworth Hospital patients to join the TTD program. This will allow the research team to assess whether a household-based intervention improves smoking cessation rates for both patients and their household members.

All participants will be followed up at 28 days, 3 months and 12 months post start of quit smoking. The smoking cessation rate will be compared to the routine TTD data set the research team has previously collected over the last year before household members were approached. This data will be acting as a control.
