Abstract
OBJECTIVES/GOALS: Fibroids during pregnancy are associated with worse obstetric outcomes. However, theres no recommendation to guide counseling. We aimed to assess the cost-effectiveness of (1) treating prevalent fibroids before pregnancy and (2) screening and treatment of fibroids against the outcomes of postpartum hemorrhage (PPH) and fetal malpresentation. METHODS/STUDY POPULATION: A decision tree model was used to compare (1) preconception myomectomy for prevalent fibroids, without treatment and (2) preconception myomectomy for prevalent cases and universal ultrasound screening with subsequent myomectomy for incident cases. Probabilities and costs, calculated from the U.S. healthcare sectors perspective, were derived from the literature. Effectiveness was measured in incident PPH or malpresentation cases per 1,000 in the population. The incremental cost-effectiveness ratio (ICER) was measured in incremental cost per case averted. One-way and probabilistic sensitivity analyses were conducted to identify influential parameters and assess the impact of parameter uncertainty. RESULTS/ANTICIPATED RESULTS: Treating known fibroids prior to pregnancy averted 65.7 PPH cases at the cost of $8,773,094 and 91.08 malpresentations at the cost of $8,163,315 (ICERs, $133,532 vs $89,628 per case averted, respectively). Universal fibroid screening with treatment of incident and prevalent cases averted 7.34 PPH cases at the cost of $3,725,619 and 2.7 malpresentations at the cost of $3,477,033 (ICERs, US$507,450 vs US$1,335,771 per case averted, respectively). Sensitivity analyses showed cost-effectiveness improved with decreased cost of myomectomy and increased proportion of prevalent and incident cases. DISCUSSION/SIGNIFICANCE: Treatment alone costs $133,532 per PPH averted and $89,628 per malpresentation averted. Likewise, screening with treatment costs $507,450 per PPH averted and $1,335,771 per malpresentation averted. Additionally, ICERs may decrease when focusing on populations where fibroid incidence and prevalence is higher, for example, among Black women.
