[Performance of exhaled carbon monoxide measurement in smoking cessation clinics and its influence on patients' willingness and behavior for smoking cessation].

Objective: To evaluate the performance of exhaled carbon monoxide measurement in smoking cessation clinics and its influence on patients' willingness and behavior for smoking cessation in China. Methods: Data of 41 566 patients who visited 257 smoking cessation clinics equipped with exhaled carbon monoxide detectors from 2019 to 2021 were selected to study the relationship between exhaled carbon monoxide measurement and patients' willingness to quit smoking as well as smoking cessation rate in those who completed follow up. Results: Only 21 470 (51.7%) of the patients received exhaled carbon monoxide measurement in the first visit. Patients who had exhaled carbon monoxide measurement were 1.87 (95%CI: 1.78-1.96) times more likely to have stronger willingness to quit smoking. The follow up results indicated that the patients with exhaled carbon monoxide measurement in the first visit were 1.10 (95%CI: 1.05-1.16) times more likely to quit smoking one month later than those without the measurement, and 1.22 (95%CI: 1.17-1.29) times more likely to quit smoking three months later than those without measurement. Conclusions: Exhaled carbon monoxide measurement can improve patients' willingness to quit smoking and increase smoking cessation rate. However, the testing rate is low in smoking cessation clinics at present. It's important to promote the equipment and utilization of exhaled carbon monoxide detector in smoking cessation clinics.目的： 探索呼出气一氧化碳检测在我国戒烟门诊中的开展及对患者戒烟意愿和戒烟行为的影响情况。 方法： 选取基本公共卫生项目戒烟门诊数据管理平台中，2019-2021年在全国257家配备呼出气一氧化碳检测仪戒烟门诊戒烟的41 566名患者数据，分析开展呼出气一氧化碳检测与患者戒烟意愿，及完成随访患者戒烟率之间的关系。 结果： 首诊时仅21 470名（51.7%）的患者开展了呼出气一氧化碳检测。通过logistic回归分析发现，检测呼出气一氧化碳的患者有强戒烟意愿的可能性是未检测患者的1.87（95%CI：1.78~1.96）倍；首诊时检测呼出气一氧化碳的患者1个月随访时戒烟的可能性是未检测患者的1.10（95%CI：1.05~1.16）倍，3个月随访时戒烟的可能性是未检测患者的1.22（95%CI：1.17~1.29）倍。 结论： 呼出气一氧化碳检测能提高患者的戒烟意愿和戒烟率。但目前该检测仪在我国戒烟门诊中的配备和使用率均较低，建议在戒烟门诊中继续推进该检测仪的配备和使用。.
