Smoking cessation interventions for hospitalized smokers: a systematic review.
BACKGROUND
A hospital admission provides an opportunity to help people stop smoking. Providing smoking cessation advice, counseling, or medication is now a quality-of-care measure for US hospitals. We assessed the effectiveness of smoking cessation interventions initiated during a hospital stay.


METHODS
We searched the Cochrane Tobacco Addiction Review Group's register for randomized and quasirandomized controlled trials of smoking cessation interventions (behavioral counseling and/or pharmacotherapy) that began during hospitalization and had a minimum of 6 months of follow-up. Two authors independently extracted data from each article, with disagreements resolved by consensus.


RESULTS
Thirty-three trials met inclusion criteria. Smoking counseling that began during hospitalization and included supportive contacts for more than 1 month after discharge increased smoking cessation rates at 6 to 12 months (pooled odds ratio [OR], 1.65; 95% confidence interval [CI], 1.44-1.90). No benefit was found for interventions with less postdischarge contact. Counseling was effective when offered to all hospitalized smokers and to the subset admitted for cardiovascular disease. Adding nicotine replacement therapy to counseling produced a trend toward efficacy over counseling alone (OR, 1.47; 95% CI, 0.92-2.35). One study added bupropion hydrochloride to counseling, which had a nonsignificant result (OR, 1.56; 95% CI, 0.79-3.06).


CONCLUSIONS
Offering smoking cessation counseling to all hospitalized smokers is effective as long as supportive contacts continue for more than 1 month after discharge. Adding nicotine replacement therapy to counseling may further increase smoking cessation rates and should be offered when clinically indicated, especially to hospitalized smokers with nicotine withdrawal symptoms.
