Abstract

Background: The effectiveness of providing feedback on spirometry results for smoking cessation remains inconclusive according to the current evidence.

Objectives: To assess the effectiveness of a motivational intervention based on spirometry results in achieving prolonged smoking abstinence (12 months post-intervention).

Design and setting: A randomised, controlled, observer-blinded, multicentre clinical trial was conducted (from January 2012 to December 2015) in 20 primary healthcare centres in the Tarragona province, Spain.

Methods: Participants, active smokers aged 35-70 without known respiratory disease, were recruited from primary healthcare centres by family doctors and nurses. They were randomly assigned to either the intervention group (IG = 308) or the control group (CG = 306). Both groups received brief smoking cessation counselling. Additionally, the IG underwent spirometry and received detailed information about the results, including lung age. The primary outcome was prolonged abstinence, defined as lasting at least 12 months and validated through cotinine measurement in urine.

Results: The prolonged abstinence rate was 7.8% in the IG, compared to 2.6% in the CG (p = 0.004). At 12 months, in the multivariate analysis, the intervention was identified as an independent factor for smoking cessation (OR 2.8; 95%CI 1.2 to 7.7), a trend maintained throughout the follow-up (HR 2.74; 95%CI 1.13 to 6.62). Moreover, according to the Prochaska and DiClemente model, the preparation or action phase to quit was also associated with smoking cessation (HR 2.55, 95%CI 1.07 to 6.09).

Conclusion: A primary care-delivered intervention involving brief counselling and detailed spirometry information proves effective in increasing abstinence rates among active smokers without known respiratory disease. Additionally, smoking cessation is also influenced by the individual's stage of change.

Trial registration: ClinicatTrials.gov NCT02153047.

基于肺活量测定的动机干预对戒烟的有效性：RESET随机试验。

背景：根据目前的证据，提供肺活量测定结果反馈戒烟的有效性仍然没有定论。目的：评估基于肺活量测定结果的动机干预在实现长期戒烟方面的有效性（12 干预后数月）。设计和设置：2012年1月至2015年12月，在西班牙塔拉戈纳省的20个初级保健中心进行了一项随机、对照、观察者盲法的多中心临床试验。方法：由家庭医生和护士从初级保健中心招募参与者，年龄35-70岁，无已知呼吸道疾病的活跃吸烟者。他们被随机分配到干预组（IG=308）或对照组（CG=306）。两组都接受了简短的戒烟咨询。此外，IG接受了肺活量测定，并收到了有关结果的详细信息，包括肺部年龄。主要结果是长期禁欲，定义为持续至少12 月，并通过尿液中可替宁的测量进行验证。结果：IG组的长期禁欲率为7.8%，而CG组为2.6%（p = 0.004）在多变量分析中，干预被确定为戒烟的独立因素（OR 2.8；95%CI 1.2至7.7），这一趋势在整个随访期间保持（HR 2.74；95%CI 1.13至6.62）。此外，根据Prochaska和DiClemente模型，戒烟的准备或行动阶段也与戒烟有关（HR 2.55，95%CI 1.07至6.09）。此外，戒烟也受到个人变化阶段的影响。试验注册：ClinicalsTrials.gov NCT02153047。

期刊介绍： The EJGP aims to: foster scientific research in primary care medicine (family medicine, general practice) in Europe stimulate education and debate, relevant for the development of primary care medicine in Europe. Scope The EJGP publishes original research papers, review articles and clinical case reports on all aspects of primary care medicine (family medicine, general practice), providing new knowledge on medical decision-making, healthcare delivery, medical education, and research methodology. Areas covered include primary care epidemiology, prevention, diagnosis, pharmacotherapy, non-drug interventions, multi- and comorbidity, palliative care, shared decision making, inter-professional collaboration, quality and safety, training and teaching, and quantitative and qualitative research methods.
