Guidelines for the Treatment of Smoking in Hospitalized Patients.

Between 15 and 27% of patients admitted to Spanish hospitals are smokers. Hospitalization is an ideal time for a smoker to decide to quit. We performed a MEDLINE search of controlled, randomized or observational studies associated with helping hospitalized patients quit smoking, published between January 1, 2002 and September 30, 2015. On the basis of the results of those studies, we have issued some recommendations for the treatment of smoking in hospitalized patients. The recommendations were drawn up according to the GRADE system. Offering the smoker psychological counselling and prolonging follow-up for at least 4 weeks after discharge is the most effective recommendation for helping hospitalized patients to quit.
