Scientific titleA randomised controlled trial to assess the feasibility, acceptability and effectiveness of tailored web- and text-based facilitation of smoking cessation in primary care
Study objectivesThe proposed trial is part of a larger programme of work in the General Practice and Primary Care Research Unit, University of Cambridge, on computer-based approaches to smoking cessation. The intervention to be evaluated in this trial consists of two components:
1. A web-based program designed to be used by a practice nurse or other smoking cessation advisor (SCA); the program generates a cessation advice report that is highly tailored to relevant characteristics of the smoker
2. A three-month program of automatically generated tailored text messages sent to the smoker’s mobile phone

The iQuit program is a potentially cost-effective approach which is designed to enhance the effectiveness of the consultation without requiring nurses to radically change the way they advise and treat smokers and to provide continuing support to smokers during their quit attempts, while reducing the need for them to attend the practice (except for the purpose of obtaining further supplies of nicotine replacement and attending for the routine NHS four-week follow-up appointment).
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedSmoking cessation
InterventionTwo groups to be compared:
1. Control group: participants will receive 'usual care' for smoking cessation
2. Intervention group: participants will receive 'usual care' for smoking cessation, plus a printed patient-tailored advice report generated by web-based software, followed by a 90-day program of patient-tailored interactive SMS text messages

Follow up dates:
Routine NHS follow up: 4 weeks from quit date
Research follow up: 8 weeks and 6 months from randomisation date
Intervention typeOther
Primary outcome measureSelf-reported effectiveness, using a self report of being abstinent from smoking for at least 2 weeks, at 8-week follow-up from randomisation date, as assessed by postal questionnaire or telephone interview (blinded interviewer).
Secondary outcome measures1. Carbon monoxide (CO)-verified self-report of being abstinent from smoking for at least 2 weeks, at 4-week follow-up from quit date
2. Self-reported prolonged abstinence (at least 3 months) at 6-month follow-up from randomisation date
Overall study start date01/04/2009
Completion date31/01/2011

Eligibility

Participant type(s)Patient
Age groupAdult
Lower age limit18 Years
Upper age limit75 Years
SexBoth
Target number of participantsTotal approx 600 (300 in each of the intervention groups)
Key inclusion criteriaPatients can be included in the study if they meet all of the criteria below:
1. Current smoker (has smoked in the 7 days prior to randomisation date)
2. Able to read English and can provide written informed consent
3. Is seriously considering quitting smoking and is willing to set a quit date within the 14 days after randomisation
4. Aged 18 - 75 years, either sex
5. Has a mobile phone and is familiar with sending and receiving SMS text messages
6. Is willing to participate in study and follow study procedures
7. Is not currently enrolled in another formal smoking cessation study or program
8. Is not using nicotene replacement therapy (NRT), bupropion (Zyban®) and varenicline (Champix®) or other pharmacotherapy at randomisation date
Key exclusion criteria1. Do not meet all of the inclusion criteria
2. Considered by their GP to be unsuitable for the project for any reason e.g. people with severe mental impairment or severely or terminally ill

Co-morbidities, for example chronic obstructive pulmonary disease (COPD), diabetes, are not excluded from the study (unless their GP considers them unsuitable). In addition, we would not exclude entry to the trial of more than one participant per household, however, should this occur, they would be assigned to the same treatment group (to minimise the potential for contamination).
