Tobacco consumption is a major public health problem, ranking second in the leading cause of morbidity and mortality worldwide, in 2010. The prevalence of tobacco smoking in hospitalized patients is evaluated around 20% and the management of tobacco reduction/cessation is an major issue for the course and outcome of many disorders.

Recent recommendations published by the French National Health Authority ("Haute Autorité de Santé", HAS) call for the involvement of all health professionals in helping patients to stop smoking and hospitalized patients are identified as a specific target. In addition, the meta-analysis of Rigotti et al. (2012) showed that the most effective programs (tobacco cessation) were those that include all patients, starting during the hospitalization with a specific follow-up of at least one month, and with the addition of nicotine replacement therapy. This combination increased the odds of successful tobacco cessation by 54%.

The project aims to evaluate the short-term efficacy (1 month) of a nurse-based program on tobacco smoking consumption in a population of hospitalized patients.

Inclusion Criteria:

• Adult patient (>= 18 years), tobacco smokers, hospitalized in one of the participating unit during the inclusion period.
• For the sake of coherence with the literature, only subjects who smoked at least one cigarette a day in the previous 30 days before the hospitalization will be considered as "smokers".
• Affiliated to the national health system
• Signed informed consent

Exclusion Criteria:

• Patients enrolled in an addiction treatment during their hospitalization stay
• Cognitive deficit that makes the informed consent and the telephone interview impossible
• Aphasia
• Patient who does not speak French
• Life expectancy below 6 months

All smoking patients hospitalized in one of the participating unit of the Saint-Louis-Lariboisière-Fernand Widal hospital (Diabetology, Cardiology, adults and adolescents Onco-hématology, Orthopedy, Oncology, Internal Medecine, Pneumology, Dermatology, Rhumatology, Psychiatry, Gastro-Entérology, Neurology) during the study period that include the 6 months preceding and the 6 months following the training.
