Participation in a workplace smoking cessation program incentivized by lowering the cost of health care coverage: Findings from the LLUH BREATHE cohort.

Introduction: Systematic analyses of workplace smoking cessation programs indicate that efficacy can be enhanced by using incentives. There is variation in the type of incentives used and their effect on participation and efficacy. The aim of our study was to examine whether lowering employee health plan costs (employee contributions, co-pays) encourage employee smokers to participate in workplace smoking cessation.

Methods: We conducted a 2014-2015 prospective cohort study of 415 employee smokers of Loma Linda University Health (LLUH). The employees were offered participation in a workplace smoking cessation program (LLUH BREATHE Initiative) with the incentive of enrollment in an employer-provided health plan that had a 50% lower employee monthly contribution and co-payment relative to the employer-provided health plan for non-participants. Participation rates and variables associated with participation were analyzed.

Results: In the LLUH BREATHE cohort, we found a very high rate of participation (72.7%; 95% CI: 69-77%) in workplace smoking cessation that was encouraged by a lower out-of-pocket health plan cost for the participating employee and/or spouse. Participation did, however, vary by gender and spouse, whereby female employee households with a qualifying smoker were more than two times more likely (employee: OR=2.89, 95% CI: 1.59-5.24; or spouse: OR=2.71, 95% CI: 1.47-5.00) to participate in smoking cessation than male employee households. The point prevalence, at four months, of abstinence from smoking among the participants was 48% (95% CI: 42-54%).

Conclusions: Our findings indicate that a workplace smoking cessation program that uses a novel reward-based incentive of lower out-of-pocket health plan costs results in a participation rate that is much higher than US norms.
