Motivational Interviewing and Air Cleaners for Smokers With COPD (MOVE COPD)

Completed · Not applicable · Has a placebo group

Conditions studied: COPD, Chronic Obstructive Pulmonary Disease

In brief

COPD is characterized by lung injury and inflammation caused by noxious particles and gases, including those emanating from cigarette smoke and air pollution. Despite the clear detrimental impact of poor air quality on respiratory outcomes, regardless of smoking status, to investigators' knowledge, there are no studied environmental interventions targeting indoor air quality to improve respiratory health of smokers, thus ignoring a potential target for harm reduction. Investigators propose a randomized controlled intervention trial to test whether targeted reductions of multiple indoor pollutants (PM, SHS and NO2) in homes of smokers with COPD will improve respiratory outcomes. Investigators have chosen a potent, multimodal intervention (active air cleaners + Motivational intervention for SHS reduction) in order to maximize the opportunity to prove that there is a health benefit to active smokers with COPD from indoor air pollution reduction.

Who can join

Age: 40 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥ 40 years,
• Physician diagnosis of COPD,
• Global Initiative for Obstructive Lung Disease (GOLD) Stage II-IV disease with Forced Expiratory Volume (FEV1)/ Forced Vital Capacity (FVC) <70% and FEV1 (% predicted) <80%. IF FEV1/FVC <70% and FEV1 (% predicted) ≥ 80%, additional requirement will apply/will be asked: COPD Assessment Test (CAT) score ≥ 10 OR exacerbation history during the last 12 months.
• Tobacco exposure ≥ 10 pack-years
• Current smoker with an exhaled Carbon Monoxide (eCO) ≥ 7 ppm to confirm smoking status. We will employ a combination of self-report and a biochemical marker to identify former-smokers. (If no eCO performed due to COronaVIrus Disease-19 (COVID-19) pandemic safety reasons, we will rely on self-report smoking status and self-report 7-day abstinence questionnaire answers)
• No home smoking ban. IF smoking is not allowed indoor (inside participant's home) then a "home air quality assessment visit" may be done.

You may not qualify if…

• Chronic systemic corticosteroids,
• Other chronic lung disease including asthma,
• Living in location other than home (e.g., long term care facility)
• Home owner or occupant planning to move or change residence within study period.
• Air Cleaners drop off (home visits temporary criteria due to COVID-19).
