Plain English Summary
Background and study aims
Smoking is an important health issue, not just in the general public but also among people with severe mental ill health, and a large proportion of people who have experienced severe mental illnesses, such as schizophrenia or bipolar disorder, smoke. Not only are these people more likely to smoke, they smoke more heavily, are more addicted to nicotine and are less likely to receive help in quitting, compared to the general population. Smoking is a preventable health hazard, with proven associations with diseases such as cancer and heart disease. Smoking behaviour contributes to the poor physical health of people with severe mental ill health, increasing their risk of an early death. The introduction of public smoking bans and other government anti-smoking strategies have highlighted the smoking issue, prompting people to consider giving up smoking. Nicotine is the addictive component of smoking, causing smokers to have extreme difficulty in quitting. Various drugs and services are available to people wanting help to quit. However, these are targeted at the general public and it is not known if and how well these would work in people with severe mental ill health. People with mental health problems do express a desire to stop smoking, but they may require different strategies and greater support to help them quit smoking. To address this problem, we aim to evaluate a ‘bespoke smoking cessation’ (BSC) service specifically tailored to individual patients with severe mental ill health.
Who can participate?
People with a diagnosis of severe mental ill health who smoke and would like to stop or cut down on smoking.
What does the study involve?
Participants will be randomly allocated into one of two groups: a bespoke smoking cessation intervention or usual GP care. Those allocated to the bespoke smoking cessation intervention will be assigned a mental health nurse or allied health professional trained to deliver smoking cessation interventions. They will work with the patient and the patient’s GP or mental health specialist to advise on anti-smoking medication and provide behavioural support in the form of information, support and motivation sessions on cutting down to quit, setting quit dates and maintaining smoking abstinence. They will also regularly check the health and smoking status of the patient. This service is similar to that used in regular smoking cessation services, but with the specific adaptations of support, medication and tailoring support to the individual needs of patients with severe mental ill health.
What are the possible benefits and risks of participating?
Stopping smoking is the single most helpful thing people can do to improve their health. Stopping smoking also has the added benefit of saving a lot of money that would have spent on cigarettes. Stopping smoking can lead to withdrawal symptoms. These are normal symptoms which may be particularly strong when someone first quits, but should lessen over time.
Where is the study run from?
The main centre of the trial is York. We also expect to recruit participants from Manchester, Durham, Leeds, Sheffield, Leeds, London and Southampton.
When is the study starting and how long is it expected to run for?
The study will start recruiting in July 2015 and will recruit for 18 months. Participants will then be followed up for 12 months.
Who is funding the study?
The trial is funded by the National Institute for Health Research (NIHR) Health Technology Assessment (HTA) programme.

Smoking Cessation for Severe Mental Ill Health Trial (SCIMITAR+): a definitive randomised evaluation of a bespoke smoking cessation service
1. A bespoke smoking cessation service for people with severe mental ill health is more clinically effective than usual GP care in helping people to stop smoking
2. A bespoke smoking cessation service for people with severe mental ill health is more cost effective than usual GP care in helping people to stop smoking

Tobacco addiction in severe mental ill health
Active intervention: bespoke smoking cessation tailored to the needs of people with severe mental ill health delivered by mental health nurse or other health professional trained in smoking cessation counselling. The nurse or other health professional will work in conjunction with the patient and patients' GP or mental health specialist to provide a smoking cessation service individually tailored to each patient. This service will be in line with current National Institute for Clinical Excellence (NICE) guidelines for smoking cessation services.
Control intervention: usual care.
The total duration for the treatment and follow-up combined will be 12 months post-recruitment. This applies for both active and control intervention arms of the trial.
Primary outcome measures
Self-reported smoking cessation at 12 months post-recruitment verified by carbon monoxide breath measurement
Secondary outcome measures
All secondary outcomes will be measured at the 6 and 12 month timepoints:
1. Reduction in the number of cigarettes smoked per day (self-report)
2. Dependence on smoking as assessed by the Fagerstrom Nicotine Dependence Questionnaire
3. Level of motivation as assessed by the Motivation to quit questionnaire
4. Patient Health Questionnaire 9 (PHQ-9)
5. Health Related Quality of Life (SF-12)
6. EuroQol EQ-5D
8. Health service use, collected via a bespoke questionnaire
