Abstract:
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.
