Specialty: Primary Care, Primary sub-specialty: Public Health; UKCRC code/ Disease: Cancer/ Malignant neoplasms of respiratory and intrathoracic organs, Cardiovascular/ Pulmonary heart disease and diseases of pulmonary circulation, Respiratory/ Lung diseases due to external agents, Stroke/ Cerebrovascular diseases
Intervention
Patients will be randomly allocated to either the control or intervention group during the consultation through the on-line iQuit software.
Control group: Participants receive usual care alone. This involves having a face to face discussion on reasons why a patient smokes and why they may want to quit; a breath test to measure CO and a discussion on stop smoking treatments that are available such as nicotine replacement therapies and Champix. Patients are also offered follow-up support and advice on how to avoid potential pitfalls that might get in the way of a successful quit attempt.
Intervention group: Participants receive the iQuit intervention. In addition to ‘usual care’ and the tailored report generated from the iQuit software, participants will begin to receive text messages the day before their quit date and 0, 1 or 2 messages each day for 90 days. The following are examples of text messages a participant might receive.
“Hi Sarah, welcome to iQuit in Practice, a personal program of quitting support. We hope you enjoy it and that it helps in your quit attempt. The iQuit team.”
“As well as removing cigarettes and ashtrays, ask any visitors not to smoke inside. Now's a great time to freshen up the curtains and wipe away any smoke stains.”
“Quitting is great for your skin. Several studies have found measureable improvements in the skin tone of quitters, often within in the first four weeks!”
“By staying quit, your immune system will start to recover, meaning you'll soon be better able to fight off colds and other illnesses.”
“After all your effort to get this far, make sure you reward yourself. It's a real achievement, and this time it's for good. :-)”
“Don't believe 'just one' is okay: A 2010 review found that even 'light' smokers were at much more risk of lung problems and cataracts compared to non-smokers.”
“Hi Sarah, great job so far. Just make sure you don't give yourself any excuses. You decided to quit because you wanted to QUIT.”
Follow up is at 4 weeks and 6 months post quit date: Follow-up is a CO test (at 4 weeks), a questionnaire and saliva test (at 6 months).

Primary outcome measure
Self-reported abstinence from smoking for 6 months endorsed by biochemical verification measured 6 months after the participant’s quit date. Abstinence from smoking will be measured 6 months after the participant’s quit date using a questionnaire (sent by the research team) followed by biochemical verification. All participants that have stated in the questionnaire they have not smoked for 6 months will be sent a kit to collect a saliva sample. The sample will be analysed for cotinine (a nicotine metabolite). If the sample is positive for cotinine then the sample will also be assayed for anabasine to differentiate whether the cotinine has come from tobacco, E-Cig or NRT.
Secondary outcome measures
1. Abstinence is measured using carbon monoxide (CO) testing at baseline and the routine follow-up 4-week appointment in the patient’s GP practice
2. Abstinence is measured through self-reporting using a questionnaire deigned for this study at 6 months (not biochemically validated)
3. Cost-effectiveness of the intervention is determined using a questionnaire at 6 months post quit date will determine NHS costs accumulated during the previous 6 months through questions on GP visits and medications prescribed, including NRTs
