Intervention(s)
|
This trial has a 2x2 factorial design. The pharmacists will recruit 16 patients per pharmacy; 160 smokers altogether. Participants will be randomised in sealed envelopes to receive:
1. Behavioural support
1.1. 52 weeks
1.2. 4 weeks
The pharmacist will give support for 52 weeks by inviting participants to set a treatment goal and provide advice on how to reduce cigarettes. Participants in the 4-week supported programme will be given the same advice with the reduction but with a different schedule. Participants will be provided with a weeks worth of Nicotine Replacement Therapy every week for the duration of their participation in the trial.
2. No support
2.1. 52 weeks
2.2. 4 weeks
Participants in the no support arms will not be given advice or support. Instead they will be given a leaflet that describes the reduction programmes, and encourages use of Nicotine Replacement Therapy (NRT) to support the reduction.
The trial will run for 52 weeks regardless of the trial arm, it is only the way they reduce the amount they smoke that will differ. The NRT will be given by the recruiting pharmacist. The participants will also be asked to provide a CO2 reading at their first appointment, at the last appointment and also after every time they have gone smoke free for a month.
