Abstract: Objectives: To determine and compare costs of a nurse-administered behavioral intervention for pregnant substance users that integrated motivational enhancement therapy with cognitive behavioral therapy (MET-CBT) to brief advice (BA) administered by an obstetrical provider. Both interventions were provided concurrent with prenatal care. Methods: We conducted a micro-costing study that prospectively collected detailed resource utilization and unit cost data for each of the two intervention arms (MET-CBT and BA) within the context of a randomized controlled trial. A three-step approach for identifying, measuring and valuing resource utilization was used. All cost estimates were inflation adjusted to 2011 U.S. dollars. Results: A total of 82 participants received the MET-CBT intervention and 86 participants received BA. From the societal perspective, the total cost (including participants’ time cost) of the MET-CBT intervention was $120,483 or $1,469 per participant. In contrast, the total cost of the BA intervention was $27,199 or $316 per participant. Personnel costs (nurse therapists and obstetric providers) for delivering the intervention sessions and supervising the program composed the largest share of the MET-CBT intervention costs. Program set up costs, especially intervention material design and training costs, also contributed substantially to the overall cost. Conclusions: Implementation of an MET-CBT program to promote drug abstinence in pregnant women is associated with modest costs. Future cost effectiveness and cost benefit analyses integrating costs with outcomes and benefits data will enable a more comprehensive understanding of the intervention in improving the care of substance abusing pregnant women.
