A Tobacco-Free Medical Campus Policy is Associated With Decreased Secondhand Smoke Exposure and Increased Satisfaction Among Military Medical Employees: Results of a Mixed-Methods Evaluation.

INTRODUCTION

Tobacco control is an ongoing concern for the U.S. Army. Although tobacco use is currently prohibited within all military hospitals and clinics, known as military treatment facilities (MTFs), no such facility had implemented a tobacco-free medical campus (TFMC) policy before 2012. This evaluation examined the effects of one Army installation's TFMC policy implementation at its medical facilities.

MATERIALS AND METHODS

Online questionnaires were distributed to medical campus employees, including Active Duty Soldiers, civilians, and contractors, before policy implementation (N = 1,210) and 12 months following policy implementation (N = 1,147). Chi-square analyses, independent t tests, and logistic regression models were utilized to examine pretest/post-test changes in employees' secondhand smoke (SHS) exposure; tobacco use, motivation to quit, and cessation; and health outcomes. Twenty-three focus groups, interviews, and informal discussions with 65 employees and patients were conducted 13 months after initial policy implementation to capture both the intended and unintended policy effects.

RESULTS

After controlling for demographic characteristics, the study found that employees had more than twice the odds of exposure to SHS in the workplace at baseline than at 12-month follow-up (odds ratio: 2.06, 95% confidence interval: 1.73-2.46, p < 0.001). Employees also reported a lower prevalence of diagnosis with chronic bronchitis (p < 0.05) at follow up compared to baseline. Although the mean number of sick days taken for respiratory illness decreased over time, results were not significant after controlling for demographic factors. No significant differences existed in tobacco-use prevalence or quit rates among tobacco users over time. Employees reported significantly higher levels of satisfaction with a TFMC policy than the original policy (p < 0.001) though this finding was moderated by smoker status such that smokers reported lower levels of satisfaction with the policy over time. Qualitative findings revealed that the most common policy effect was that the policy caused smokers to change the location of where they used tobacco to off campus. Findings further revealed several unintended policy effects, including safety concerns and greater visibility of smokers in front of the MTF.

CONCLUSION

The first Army MTF TFMC policy was associated with reported reductions in SHS exposure and improvements in some short-term health outcomes. The policy had no observed association with tobacco-use prevalence, motivation to quit, or cessation at 12-month follow-up. Focus group participants discussed several positive and negative policy effects. These policies should be expanded and studied in more depth across military installations, and policy makers should plan mitigation strategies to reduce unintended effects. This is an important step in military tobacco control, but additional efforts will be necessary to curb tobacco use within this population.
