This randomized controlled trial assessed the efficacy of a smoking relapse prevention program featuring 3 postdischarge telephone contacts with subjects who had quit smoking on hospitalization.


Patients were randomly assigned to public health nurse-mediated behaviorally oriented in-patient counseling focused on relapse prevention (control group, n = 49), or the same inpatient counseling with postdischarge telephone contacts at 7, 21 and 42 days after discharge (intervention group, n = 57). The main outcome measure, smoking cessation rate, was obtained from self-reports at 3, 6 and 12 months after discharge. Smoking cessation at 12 months after discharge was confirmed by urinary nicotine concentration.


At 3, 6 and 12 months smoking cessation rates were 83%, 63% and 56% for the intervention group, and 76%, 65% and 51% for control group. After adjustment for sex, age, having any complication, number of family members, smoking status on admission, strength of nicotine dependence and self confidence to quit smoking, the odds ratio of cessation among the intervention group were 1.46 (95% confidence interval (CI): 0.48-4.47), 0.82 (95% CI: 0.31-2.17) and 0.99 (95% CI: 0.40-2.45) at 3, 6 and 12 months after discharge, respectively.


This program had limited efficacy to maintain postdischarge smoking abstinence. We should re-consider the modality of smoking cessation program for relapse prevention among hospitalized patients.
