Design outcomes

Primary

MeasureTime frame
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

MeasureTime frame
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
