Comparing the effects of nicotine replacement therapy and nursing counseling on smoking cessation among the candidates for coronary artery bypass graft surgery: A clinical trial

Abstract

Background: There is limited data about the effects of smoking cessation (SC) strategies among the candidates for coronary artery bypass graft (CABG) surgery. Objectives: This study aimed to compare the effects of nicotine replacement therapy (NRT) and nursing counseling (NC) on SC among the candidates for CABG. Methods: This randomized controlled trial was made in the heart center of Afshar hospital, Yazd, Iran. Sixty candidates for elective bypass graft were recruited and were randomly allocated either to a NC or a NRT group. Study interventions were implemented from 3 weeks before to 3 weeks after the surgery. Before and after hospitalization for the surgery, patients in the counseling group received telephone counseling while during their 1-week hospital stay, they received face-to-face counseling. Patients in the NRT group received nicotine gums before and after hospitalization and were treated with nicotine patches during their 1-week hospital stay. Data were collected through three questionnaires. The Chi-square and the independent-sample t tests were run to analyze the data. Results: SC rate in the counseling group was significantly higher than the NRT group (63.3% vs. 33.3%; P = 0.038). Moreover, cessation rate among the participants with lower nicotine dependency was significantly greater than those with moderate-to-severe dependency (P = 0.01). Conclusion: NC is more effective than NRT in improving SC rate among the candidates for CABG.
