This study assessed a newly set-up, hospital-based smoking cessation clinic with regard to continuous abstinence rates and the effectiveness of concomittant nicotine replacement therapy.
Smoking status of 369 participants of this 8-week cognitive-behavioural smoking cessation group programme was obtained using exhaled carbon monoxide at the end of the course as well as self-report 6 months after the course. In addition to demographic data, FTND score, SDS score, and usage of nicotine replacement products were recorded.
Overall, 29.8% of all participants reported to have been continuously abstinent for 6 months after the course. Success rates increased significantly during the first year after initiation of the programme (from 15 to 35%, p<0.001), indicating a learning process of the staff running the course. Nicotine replacement therapy was used by 51.3% of participants, but 58% of these discontinued its use within 5 weeks. Nicotine substitution for more than 5 weeks was associated with a 50% success rate after 6 months.
Our data indicate a learning effect of smoking cessation course staff and a possible minimum duration required for nicotine replacement to be effective.
The observed learning effect in smoking cessation programmes should be considered when evaluating newly established interventions of this kind. Patients tend to stop nicotine replacement therapy too early, thereby decreasing their chances of middle-term abstinence.
本研究评估了一家新设立的、以医院为基础的戒烟诊所的持续戒烟率以及同时进行的尼古丁替代疗法的效果。
采用呼出一氧化碳检测以及课程结束6个月后的自我报告，获取了369名参加为期8周的认知行为戒烟小组项目的参与者的吸烟状况。除人口统计学数据外，还记录了尼古丁依赖测试（FTND）得分、抑郁自评量表（SDS）得分以及尼古丁替代产品的使用情况。
总体而言，29.8%的参与者报告在课程结束后持续戒烟6个月。在项目启动后的第一年，成功率显著提高（从15%提高到35%，p<0.001），这表明负责该课程的工作人员有一个学习过程。51.3%的参与者使用了尼古丁替代疗法，但其中58%的人在5周内就停止了使用。尼古丁替代超过5周与6个月后的成功率达到50%相关。
我们的数据表明了戒烟课程工作人员的学习效果以及尼古丁替代疗法有效的可能最短持续时间。
在评估此类新设立的干预措施时，应考虑戒烟项目中观察到的学习效果。患者往往过早停止尼古丁替代疗法，从而降低了中期戒烟的机会。
