Some Recent Developments on Financial Incentives for Smoking Cessation Among Pregnant and Newly Postpartum Women.

Abstract

Smoking during pregnancy is a leading preventable cause of poor pregnancy outcomes and immediate and longer-term adverse health outcomes among exposed offspring. Developing more effective smoking-cessation interventions for pregnant women has been a public-health priority for more than thirty years. We review developments over the past three years (2012-15) on the use of financial incentives to promote smoking cessation among pregnant women. We searched the literature for reports on primary and secondary analyses and reviews of controlled trials on this topic published in peer-reviewed journals using the search engine PubMed, reviewed bibliographies of published articles, and consulted expert colleagues. The search revealed several important developments, with the following three being especially noteworthy. First, the review identified four new randomized controlled trials, three of which further supported the efficacy of this treatment approach. One of the three trials supporting efficacy also included the first econometric analysis of this treatment approach showing financial incentives with pregnant smokers to be highly cost-effective. Second, two Cochrane reviews were published during this 3-year period covering the more recent and earlier efficacy trials. Meta-analyses in both reviews supported the efficacy of the approach. Lastly, the first effectiveness trial was reported demonstrating that financial incentives increased abstinence rates above control levels when implemented by obstetrical clinic staff in a large urban hospital working with community tobacco interventionists. Overall, there is a growing and compelling body of evidence supporting the efficacy and cost-effectiveness of financial incentives for smoking cessation among pregnant women.
