Scientific titleA randomised controlled trial on the efficacy of exhaled carbon monoxide measurement plus brief physician's advice for smoking cessation
Study objectivesSmoking is the leading cause of preventable death in industrialized countries. It has long been known that the effects of tobacco on health are multiple. The tobacco causes or encourages the development of different cancers, is the major cardiovascular risk factor, the most important known cause of chronic obstructive pulmonary disease and a risk factor for many health problems. Despite this knowledge, the prevalence of smoking in our country remains high. According to the National Health Survey of 2006 in the adult population, 31.56% men and 21.51% of women are daily smokers. Of these, 79% men and 70% of women smoke 10 or more cigarettes daily.

Hypotheses:
1. The implementation of exhaled CO2 monitoring by cooximetry for smokers in precontemplative or contemplative phase of quitting, improves the quit rate at 12 months by 5% more than brief physician's advice alone which achieves minimum quit rates of 5-7%

2. The implementation of exhaled CO2 monitoring by cooximetry for smokers in precontemplative or contemplative phase of quitting, reduces cigarette consumption at 12 months more than brief physician's advice alone

3. The implementation of exhaled CO2 monitoring by cooximetry for smokers in precontemplative or contemplative phase of quitting, increases the motivation to quit smoking at 12 months more than brief physician's advice alone
Ethics approval(s)The Ethics Committee on Human Research of the Balearic Islands approved on the 24th of September 2008 (ref: IB 985/08)
Health condition(s) or problem(s) studiedSmoking cessation
InterventionPatients will be randomised to either
1. Control Group (CG): Brief face-to-face anti-smoking advice from the physician during patient consultation
2. Intervention Group (IG): Brief advice plus exhaled CO measure
There will be a follow-up evaluation at 6 months of inclusion and at 12 months.
Intervention typeOther
Primary outcome measureSustained abstinence (at 6 and 12 months) validated by urine cotinine test
Secondary outcome measures1. Prevalence of smoking cessation, self reported and confirmed by both cotinine test
2. Cigarettes reduction
3. Variation in phase of the abandonment of smoking
Overall study start date15/10/2010
Completion date15/10/2012
