Electronic Cigarettes as a Harm Reduction Strategy Among Patients With COPD

Electronic Cigarettes as a Harm Reduction Strategy Among Patients With COPD

The study team proposes a two-arm pilot study randomizing participants with COPD who smoke combustible cigarettes (CC) to counseling + NRT (standard of care) or counseling + e-cigarettes.

Globally, chronic obstructive pulmonary disease (COPD) is projected to be the third largest cause of death by 2030 and in the US over 16 million people have COPD. Smokers are four and a half times more likely to develop COPD than non-smokers, with the likelihood of COPD increasing progressively with the duration and intensity of smoking. Among those with COPD, smoking cessation is the most effective means of slowing the decline of lung function and overall disease progression. Patients at all stages of COPD benefit from quitting smoking. Over 90% of COPD deaths occur in current smokers, however 47.1% of people with COPD continue to smoke. Electronic cigarettes (E-cigarettes) could help people reduce the harm of combustible cigarettes (CC) through reductions in number of Cigarettes per Day (CPD) or quitting CC completely by addressing both nicotine and behavioral dependence. Although there are associated health risks, all available evidence indicates that E-cigarettes are safer than CC. Unlike CC, e-cigarettes are not associated with coronary heart disease or myocardial infarction. The purpose of this mixed methods study is to identify barriers and facilitators, as well as to assess preliminary effectiveness of e-cigarettes as a harm reduction strategy among people with COPD.

Inclusion Criteria:

1. an ambulatory ICD-10 code for COPD in the last 12 months and a COPD Assessment Tool (CAT) score on the screening ≥10.
2. ages 21-75 (the legal age for purchasing e-cigarettes is 21)
3. current CC smokers (more than 5 packs in a lifetime; smokes 4 or more days/week)
4. smokes at least 10 cigarettes per day on days they smoke CC
5. motivated to quit smoking (at least a 5 on a 10-point Likert scale)
6. Participants must be able to provide consent, agree to be randomized and followed-up with, a working telephone number and/or a system with teleconferencing capabilities (e.g. smartphone or computer), a phone with text messaging capabilities, and be willing to use an e-cigarette or NRT for 12 weeks. To reduce attrition, participants will be asked to provide one additional contact as a backup for follow up on appointments.

Exclusion Criteria:

1. A CAT score >30 representing severe COPD
2. are pregnant (as determined by urine pregnancy test for women under age 52) or breastfeeding (self-reported). Women of childbearing age must also be willing to use an approved form of birth control during the course of the study if not practicing abstinence. Approved birth control methods include: hormonal birth control (e.g. "the pill"), barrier methods (e.g. condoms, diaphragm), and intrauterine devices (IUDs).
3. diagnosis of any medical condition (unstable angina/heart disease) or psychiatric condition precluding use of nicotine patch or gum as determined by the MD of this study, Dr. Scott Sherman (NYS license #171632), or by the subject's primary care doctor.
4. reporting using NRTs or e-cigarettes within the last 30 days
