Plain English Summary

Background and study aims
Smoking remains the leading cause of preventable illness and death in England. Evidence shows that brief advice to stop smoking from a GP together with an immediate offer of support is effective at encouraging smokers to quit. Despite this, many people with smoking-related chronic illnesses continue to do so despite being repeatedly offered help to quit. For these ‘ hardcore’ smokers, alternative brief advice interventions need to be explored. Electronic cigarettes (‘e-cigarettes’) are increasingly used by smokers not seeking treatment, many of whom reduce smoking and stop without initially intending to do so. The aim of this study is to test an alternative approach to smoking management designed to support people who have a smoking-related illness reduce their smoking and quit.

Who can participate?
Adults aged 18 years or older who is a current smoker.

What does the study involve?
GPs and nurses receive online training on how to give a brief advice intervention to smokers who do not want to stop but have a smoking-related illness. Patients who are smokers with a long-term condition attend their usual annual review appointment of their condition, where the GP or nurse discuss their smoking. Those who decline referral to NHS stop smoking services (SSS) and smoking cession medication are randomly allocated to one of two groups. Those in the first group receive nothing beyond the usual care already provided. Those in the second group are given brief advice and an offer to try an e-cigarette with technical support provided from an online help forum and telephone call-back service run by experienced e-cigarette users. Consultations are audio-recorded to see how well GPs and nurses followed the training and which communication strategies worked well. Participants are interviewed after taking part to see how they felt about being assisted in this way by their GP or nurse. The study will look at whether more people stop or halve their smoking in the short-term.

What are the possible benefits and risks of participating?
Participants may benefit from reducing their smoking. There are no direct risks with participating.

Scientific title

Management of Smoking in primary Care: A randomised controlled trial on the effectiveness of GP/nurse promotion of e-cigarettes in supporting reduced smoking and abstinence in hardcore smokers with smoking-related chronic disease



Study hypothesis

The aim of this study is to examine the feasibility, acceptability and effectiveness of GP/nurse promotion of e-cigarettes to support smoking reduction and cessation in hardcore smokers with smoking-related chronic diseases.

Smoking cessation and reduction


Smokers with a smoking-related chronic disease and who have no intention of stopping immediately or seeking cessation support are randomised to one of two groups if they decline referral to NHS stop smoking services (SSS) and smoking cessation medication during a routine annual review appointment with their GP or Practice Nurse: an intervention group offered encouragement by their practitioner to use an e-cigarette, or a standard care control group who will receive nothing beyond the usual care already provided prior to randomisation.

Participants in the intervention group are offered an e-cigarette starter pack and accompanying practical support booklet, containing links to a telephone call back service for technical support and a dedicated study-website. Participants are followed-up at two months and eight months after their annual review appointment.

Drug names

Primary outcome measure

1. The first primary outcome is 7-day point-prevalence abstinence from smoked tobacco at two months. Abstinence is defined as complete self-reported abstinence from smoking – not even a puff – in the past seven days, accompanied by a salivary anabasine concentration of <1ng/ml.
2. The second primary outcome is reduction in cigarette consumption at two months. Reduction is defined as a 50% reduction in self-reported cigarettes per day on each of the last seven days at two months compared with baseline consumption, accompanied by evidence of reduced smoke intake indicated by salivary anabasine concentrations lower than baseline.

Secondary outcome measures

Secondary outcome measures for abstinence include 7-day point prevalence abstinence measured at eight months, biochemically confirmed by an exhaled CO of <10 ppm. Six-month prolonged abstinence will be measured using the Russell standard criteria, defined as smoking fewer than five cigarettes between two and eight month follow-ups, confirmed by an anabasine concentration of <1ng/ml at two months and an exhaled CO concentration of <10ppm at eight months.
