Plain English summary of protocol
Background and study aims
Tobacco smoking is the largest avoidable cause of premature death and disability in the UK. Half of all lifelong smokers die as a consequence of their smoking, typically from lung cancer, chronic obstructive pulmonary disease (lung disease) or cardiovascular disease (heart and blood vessel disease). Average life expectancy among smokers is 10 years less than those who have never smoked, which is equivalent to nearly 3 months of life lost for every year smoked after the age of 35. A previous study found that identifying smokers admitted to hospital and delivering support to help them quit smoking as a default service can help increase the amount of smokers who want to quit. However, it was also found that many patients started smoking again (relapsed) when they were discharged from hospital. This study is looking at whether providing outpatient support after an inpatient stop smoking service can help to reduce relapse rates. The aim of this study is to test the effectiveness of this program at helping prevent patients from relapsing to smoking after they are discharged from hospital.
Who can participate?
All adult patients admitted for at least 24 hours to any participating inpatient ward at Nottingham City Hospital who are current smokers or have smoked within the seven days before admission to hospital.
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group receive usual care, which involves being given advice from a trained councilor at their bedside about stopping smoking. Those in the second group are offered advice at their bedside but are also offered a home visit within 24 hours of being discharged from hospital in order to receive a face-to-face behavioural support program designed to help stop them from starting smoking again. For all participants, whilst on the ward, the amount of carbon monoxide (a harmful gas present in cigarettes) in their body measured by breathing into a special monitor. This test is then repeated four weeks later.
What are the possible benefits and risks of participating?
The main benefit of taking part for study participants is help to stop smoking, reducing illness and improving quality of life and life expectancy. There are no risks to participants in the trial, although some people may have an adverse reaction to nicotine replacement products. However, all participants will be supported by a fully trained smoking cessation practitioner and so any adverse reaction to therapies will be quickly rectified.

| Scientific title | Randomised controlled trial to test the effectiveness of an intensive home support intervention for newly abstinent smokers leaving hospital |
| Study objectives | The aim of this study is to investigate the effectiveness of a multi-component intervention to prevent relapse to smoking after hospital discharge. |
| Ethics approval(s) | East Midlands - Nottingham 2 Research Ethics Committee, 06/04/2016, ref: 16/EM/0088 |
| Health condition(s) or problem(s) studied | Specialty: Health services and delivery research, Primary sub-specialty: Health services and delivery research; UKCRC code/ Disease: Other/ Symptoms and signs involving the circulatory and respiratory systems, Other/ General symptoms and signs |
| Intervention | Patients will be informed of the study during their period of inpatient stay. If they are a smoker, during the last 24 hours of their stay they will be asked if they would like to take part in the research. Patients will then be individually randomised into either the usual care arm or the intervention arm of the trial. Usual care arm: Patients will receive smoking cessation advice in hospital and at home according to the recommendations set out in NICE (PH48) guidance, including pharmacotherapy and behavioural support before leaving hospital, referral to NHS Stop Smoking Service for continued care after discharge, and ascertainment of smoking status at 4 weeks; participants will also be asked to consent to smoking status ascertainment at three months. Intervention arm: Patients will be offered cessation advice at their bedside but will also be offered a home visit in the 24 hours post discharge to deliver face-to-face behavioural support designed to reduce the risk of relapse. This will include advice on changing routines to avoid smoking cues when in the home; help with strategies to deal with cravings and high risk situations; help to remove physical smoking cues (e.g. cigarettes, ashtrays, other paraphernalia) from the home; ensuring continuity of supply and advice on optimal use of pharmacotherapy; engagement with and provision (if accepted) of nicotine replacement therapy to promote smoking cessation or at least temporary abstinence in the home by family or other household members or regular visitors who smoke; the offer of 24-hour indoor air quality monitoring, using a using a battery-operated Sidepak Aerosol Monitor AM510 (TSI Instruments Ltd, High Wycombe UK) positioned in the main living area, in the first week after discharge from hospital and again at 12 weeks, as motivation to sustain a smoke-free home; and a range of other support aimed at supporting smoking cessation. For participants who decline a home visit, the above support options will be offered as far as possible through telephone contact and delivered to the extent accepted by the participant. Ascertainment of smoking status will be undertaken at both 4 and 12 weeks. Both intervention and usual care participants will be asked, as part of the study, to undergo a carbon monoxide (CO) measure (breath test) while on the ward and will be contacted at 4 weeks and 12 weeks after leaving hospital to ask about the patients smoking status and (if appropriate) take further CO measures. |
| Intervention type | Other |
| Primary outcome measure | Continuous abstinence from smoking assessed by measuring carbon monoxide levels (<6ppm) at baseline and 4 weeks post discharge from hospital. |
| Secondary outcome measures | Current secondary outcome measures as of 08/05/2019: 1. Continuous abstinence from smoking assessed by measuring carbon monoxide levels (<6ppm) at 3 months post discharge from hospital 2. Continuous abstinence from smoking, self-report by participant at baseline, 4 weeks and 3 months post-discharge from hospital 3. Self- reported reduction in cigarette consumption assed by recording the difference in the number of cigarettes smoked per day at baseline and 4 weeks post discharge from hospital 4. Self-reported presence of a smoke free home, assessed by asking participant if anyone smokes inside the home at baseline 4 weeks and 3 months post-discharge from hospital 5. Utilisation of each component of the complex intervention measured through participant self-reporting at 4 weeks and 3 months post-discharge from hospital Previous secondary outcome measures: 1. Continuous abstinence from smoking assessed by measuring carbon monoxide levels (<6ppm) at 3 months post discharge from hospital 2. Continuous abstinence from smoking, self-report by participant at baseline, 4 weeks and 3 months post-discharge from hospital 3. Self- reported reduction in cigarette consumption assed by recording the difference in the number of cigarettes smoked per day at baseline and 4 weeks post discharge from hospital 4. Self-reported presence of a smoke free home, assessed by asking participant if anyone smokes inside the home at baseline 4 weeks and 3 months post-discharge from hospital 5. Changes in maximum concentrations of P.M2.5 and the proportion of time PM2.5 concentrations exceed WHO recommended safe levels of maximum exposure of 25 µg/m3 per 24-hour period, measured using an AM510 Sidepak aerosol monitor 24 to 48 hours, 4 weeks and 3 months post-discharge from hospital 6. Utilisation of each component of the complex intervention measured through participant self-reporting at 4 weeks and 3 months post-discharge from hospital |
