PURPOSE: To determine whether switching from tobacco cigarettes to EC reduces shortness of breath and coughing, and increases activity.

METHODS: We searched our Electronic Medical Record System and identified 205 patients who reported using EC as part of a tobacco smoking cessation plan. Research assistants conducted telephone surveys with those who agreed to participate. The survey included questions about smoking history, smoking cessation history, and changes in symptoms (shortness of breath and coughing) and activity level since beginning EC use. We used STATA Version 13 to calculate a test of proportion to compare reported changes in symptoms in smokers versus ex-smokers.

RESULTS: Fifty eight patients agreed to participate in the study. 57% were female. Mean age was 53.6 (SD = 15) years. 90% reported graduating from high school.47% reported some college education.40% of respondents reported being employed, 33% retired and 17% disabled. 90%of respondents reported daily EC use. Fifty eight (28%) patients agreed to participate in the study. Of these patients, 57% were female and the mean age was 53.6 (SD 15) years. The majority of patients (90%) reported they had graduated from high school and 47% reported having some college education. Forty percent of respondents reported being employed, 33% retired and 17% disabled. Ninety percent of respondents reported daily EC use. The majority of patients who used EC and had eliminated tobacco smoking, reported decreased shortness of breath and cough. There was a trend toward stronger improvements among ex-smokers (compared to current smokers) for Cough (p=0.11), Shortness of Breath (p=0.11) and Activity Level (p=0.06). Table 1.

CONCLUSIONS: Electronic cigarette (EC) use may reduce smoking symptoms and may lead to improved activity in patients using EC’s for tobacco smoking cessation. Our study results showed trends toward decreasing smoking symptoms, especially in individuals who stopped smoking altogether, particularly with regard to increased activity.

CLINICAL IMPLICATIONS: While our study results were not statistically significant, the clinical effects of transitioning from tobacco to EC need further study with a larger sample, in order to give guidance to clinicians and the public.
