Scientific title	An intervention to stop tobacco use among patients suspected of tuberculosis (TB): an evaluation of an integrated approach
Study acronym	TATO
Study objectives	1. What is the effect of an intervention, based on the World Health Organization (WHO) 'five steps to quit' model and consisting of training of health professionals, a desk-guide, a desktop patient education tool and leaflet, on patients' point and continuous abstinence from tobacco use? [Effect evaluation] 2. To what extent do the health professionals communicate risks of tobacco use and benefits of its cessation to their patients? What are their experiences and opinions about this strategy? [Process evaluation] 3. How do patients experience the intervention for tobacco addiction? [Ethical evaluation] 4. What is the incremental cost-effectiveness ratio of the intervention for tobacco addiction compared to usual care? [Economic evaluation]
Ethics approval(s)	Research Ethics Committees of TB programme and Pakistan Medical Research Council, approval pending as of 05/12/2008.
Health condition(s) or problem(s) studied	Tuberculosis and tobacco use
Intervention	A total of 22 primary care health centres will be selected (11 each for control and intervention arms) and 50 patients recruited with suspected tuberculosis in each of these centres. In the intervention arm, recruited patients will be given the 'five steps to quit' model. This is based on the evidence-based recommendations for treatment of tobacco addiction published by WHO in 2001. Participants will be: 1. Asked about the status of nicotine use 2. Advised about the benefits of stopping nicotine use 3. Assessed for their motivation to stop its use 4. Assisted in stop attempts through various therapeutic options 5. Provided with an information leaflet 6. Asked to arrange a follow-up In the control arm, patients will be provided with education leaflets only. The trial will continue for six months and a review at 1 and 6 months will take place to assess smoking status and clinical outcomes in both arms.
Intervention type	Other
Primary outcome measure	1. Point abstinence at 4 weeks: the proportion of trial participants who have completely given up all forms of nicotine use at four weeks after the completion of NRT, bupropion and/or brief counselling therapy 2. Continuous abstinence up to 6 months: proportion of trial participants who remained abstinent from 4 weeks onwards up to six months 3. We will also measure tobacco use, e.g. number of cigarettes smoked per day to estimate any reduction in tobacco use secondary to the intervention
Secondary outcome measures	1. Incidence of various adverse affects secondary to therapy 2. Economic outcomes assessed in terms of healthcare cost to get one person to stop smoking at four weeks. Healthcare cost will include the treatment cost, the average duration of health professionals' time spent with the patients during assessment, advice and counselling. 3. Process outcomes include: 3.1. The proportion of tobacco users who decide to quit and registered to receive 'five steps to quit' intervention 3.2. The proportion of people registered who continue follow-up for the full period planned
