Brief Summary:
Investigators will examine whether adding financial incentives to current best practices for smoking cessation during pregnancy (i.e., referral to pregnancy-specific counseling using a telephone quit line) increases cessation rates and improves infant health. While more expensive upfront compared to best practices alone, the investigators hypothesize that this treatment approach will be economically justified by the later cost savings associated with more women quitting, having healthier babies, and needing less healthcare. It should also help to reduce the greater risk for health problems often seen among those who less well off economically.
Detailed Description:
Smoking during pregnancy is the leading preventable cause of poor pregnancy outcomes in the U.S. Most pregnant smokers continue smoking through pregnancy producing serious immediate and longer-term adverse health consequences for the infant. Smoking during pregnancy is highly associated with economic disadvantage and a substantive contributor to health disparities.
Efficacious interventions are available, but cessation rates are low (\<20%) and improvements in birth outcomes often modest or absent. Current treatments usually entail relatively brief, lower-cost interventions (e.g., pregnancy specific quit lines). There is broad consensus that more effective interventions are sorely needed. This team of investigators has developed a novel behavioral economic intervention in which women earn financial incentives contingent on smoking abstinence. In a metaanalysis of treatments for smoking during pregnancy, effect sizes achieved with financial incentives were several fold larger than those achieved with lower intensity approaches or medications. The intervention also appears to improve birth outcomes and increase breastfeeding duration. While highly promising, further research is needed in at least three areas. (1) The evidence on birth outcomes and breastfeeding is from studies that combined data across trials rather than a single prospective trial, (2) whether the intervention produces other postpartum improvements in health has not been investigated, and (3) the overall cost-effectiveness of this approach has not been examined.
To examine these unanswered questions, the investigators are proposing a randomized, controlled clinical trial comparing the efficacy and cost effectiveness through one year postpartum of current best practices for smoking cessation during pregnancy vs. best practices plus financial incentives among 230 pregnant, Medicaid recipients. A third condition of 115 pregnant nonsmokers matched to the smokers on sociodemographic and health conditions will be included as well to compare the extent to which the treatments reduce the burden of smoking and to estimate how much more might be accomplished by further improvements in this incentives intervention without exceeding cost-effectiveness.
The investigators hypothesize that best practices plus financial incentives will be more effective than usual care practices alone, that the incentives intervention will be cost effective, and that while adding the incentives reduces a greater proportion of the health and economic burden of smoking than best practices alone, more can be done while remaining cost effective.
Overall, the proposed study has the potential to substantially advance knowledge on cost-effective smoking cessation for pregnant women. Importantly, because of the strong association between smoking during pregnancy and economic disadvantage, the proposed study also has the potential to contribute new knowledge relevant to reducing the serious challenges of health disparities.
