BackgroundRecent clinical trials suggest that e-cigarettes may be more effective for smoking cessation than traditional cessation aids, yet primary care physician (PCP) practices regarding e-cigarette recommendations for smokers have not been studied in-depth.ObjectiveTo identify factors influencing PCP recommendation of e-cigarettes for smoking cessation.DesignDiscrete choice experiment and survey.ParticipantsFlorida PCPs.MeasuresThe survey included a discrete choice experiment in which PCPs indicated whether they would recommend e-cigarettes for each of 8 hypothetical patient profiles with the following contrasting characteristics: e-cigarette use, interest in approved cessation methods, smoking intensity, prior experience with approved cessation medications, quit intention, age, and comorbidity. Responses were summarized using descriptive statistics and standardized scores (SS).Key ResultsThe sample (n = 216) was predominately male (76%), white (66%), and non-Hispanic (78%), and most respondents had held their medical degree for 20+ years (77%). The response rate was 28.7%. Most PCPs thought e-cigarettes were at least somewhat effective for smoking cessation (66%) and lowering disease risk (65%); 31% perceived e-cigarettes to be equally/more effective than traditional cessation aids. PCPs were split regarding whether e-cigarettes were less (50%) or equally harmful (38%) as cigarettes. Yet, few were very confident in their ability to counsel patients on e-cigarettes risks (27%) or benefits (15%). PCPs recommended e-cigarettes in 27% of patient profiles they evaluated. The most important factors influencing the decision to recommend or not recommend e-cigarette were patients' prior use of nicotine replacement therapy with (SS = 0.22, 95% CI = 0.17-0.27) and without use of other medications for cessation (SS = 0.18, 95% CI = 0.13-0.23), and being middle age (50 years old) with chronic obstructive pulmonary disease (SS = 0.16, 95% CI = 0.10-0.23).ConclusionsConsidering the increased patient use of e-cigarettes and increasing use for cessation, this study highlights the need for guidelines and education to aid PCPs' counseling of patients about e-cigarette use.© 2021.
