简要总结
The purpose of this randomized control trial is two- fold. The primary hypothesis of the study is that smoking cessation counseling delivered through trained medical students will lead to higher rates of abstinence amongst patients in the intervention group, as compared to a control group, when measured by self-reported and biochemical testing at 6 months after enrolment .
The secondary hypothesis is that medical students engaging in a structured curriculum that includes counseling hospitalized smokers will show demonstrable increases in knowledge, confidence in their abilities, and use of smoking cessation techniques in regular practice.
详细描述
India is the 2nd largest consumer of tobacco in the world, with 275 million Indians using tobacco. Each hospitalization is an opportunity for providers to motivate their patients to quit. However, the Indian medical curriculum typically offers little training in the skills required to successfully counsel a patient to quit smoking. The investigators hypothesize that trained medical students can increase subsequent quit rates among hospitalized smokers, while acquiring skills in tobacco cessation counseling.
The investigators propose a 2-armed multicenter randomized controlled trial (RCT) that will compare the effectiveness of standard hospital practice versus a medical student-guided smoking cessation program initiated inpatient and continued for three months after discharge. The target study population includes current smokers admitted to the general medicine, pulmonary and cardiology wards. These patients will be randomized to receive either usual care or the intervention. The intervention group will receive both inpatient and longitudinal post-discharge telephone counseling by medical students who have successfully completed a training workshop in tobacco cessation counseling and pharmacotherapy. The students can also recommend nicotine replacement therapy (NRT) to the patient if indicated. The control group will receive counseling and/or NRT at the discretion of the treating physician. They will not receive phone based counseling after discharge.
Patients from both groups will be asked to report their quit status 6 months after enrolment.

结局指标
主要结局
Biochemically verified 7 day quit rate measured 6 months after enrolment.
时间窗: 6 months from enrolment
At 6 months from enrolment, patients will be asked to report abstinence from smoking over the last 7 days (No more than 5 cigarettes in total since quit date); those who claim to have quit will be asked to provide biochemical confirmation by exhaled carbon monoxide breath testing (\<10 Parts Per Million will be considered a verified quit attempt).
次要结局
- Correlation between verified quit rates at 6 months and FTND scores at enrolment(6 months from enrolment)
- Agreement between self reported quit 7 day quit rate and biochemically verified 7 day quit rate, measured at 6 months from enrolment(6 months from enrolment)
- Biochemically verified 90 day quit rate, measured 6 months after enrolment(6 months from enrolment)
- Qualitative analysis of student attitudes towards smoking cessation counseling(12 months after training)
- Number of patients achieving a 50% reduction in the number of cigarettes /bidis smoked in a week, measured at 2 and 6 months after enrolment(2 and 6 months from enrolment)
- Number of patients who report having quit smoking in the last 7 days (irrespective of biochemical verification)(2 and 6 months from enrolment)
- Pre-post analysis of medical student knowledge about counseling techniques and pharmacotherapy(6 weeks and 12 months after training)
- Qualitative analysis of the feasibility and acceptability of the intervention(12 months after training)
- No of patients who have refrained from using smokeless tobacco in the last 7 days, measured at 6 months.(6 months from enrolment)
