Effect of a Smoking Cessation Program on Inpatients in the Largest Hospital in Southern Iran

Abstract

Background: There is evidence that cessation programs can be effective for hospital inpatients. Hence, the aim of this study was to investigate the effects of such programs and factors that may affect success.

Methods: This study was carried out on in‑patient users of tobacco in Shiraz
Hospital, Iran in 2015. After implementing the inclusion criteria, a study population was selected using a convenience sampling method. Participants were contacted monthly by study personnel concerning certain aspects of their tobacco cessation program. The study lasted 6 months. Data analyses involved survival analysis using Kaplan–Meier analysis, log‑rank test, and multivariate Cox regression modeling.

Results: The study included 425 in‑patient smokers of which 328 (77.2%) were male. Median follow‑up time was 96 days (interquartile range: 20–150). Cessation survival rates were 76% at 1 month, 63% at 2 months, and 61% at 3 months. From the 4th month onward rates remained unchanged at 60%. Univariate analyses with variables such as time since last smoking, consumption type, interval between wake‑up and consumption, the severity of dependence and interest in smoking cessation were statistically signifcant as to cessation survival rate (P ˂ 0.05).
After adjusting the confounding variables based on multivariable analyses, results indicated that consumption type, the severity of dependence and interest in smoking cessation were the most important predictors of cessation survival rates among in‑patient smokers.

Conclusions: Findings indicated that application of the cessation program among our group of inpatients appears to have been an effective intervention that produced an extended period of no smoking.
