Objective:
To assess the potential effectiveness and costs of 4 commonly used strategies to manage abnormal early pregnancies (AEPs).
Study Design:
A decision analysis model was constructed to compare 4 strategies to manage AEPs: (1) observation, (2) medical management, (3) manual vacuum aspiration (MVA), and (4) dilation and curettage (D&C).
Results:
MVA was the most cost-effective strategy, at dollar 793 per cure, for a total cost of dollar 377 million per 500,000 women and a cure rate of 95%. D&C was more effective than MVA, with a cure rate of 99%, but was more expensive (dollar 2,333 per cure, for a total cost of dollar 1.2 billion). D&C cured 20,000 more patients than MVA; however, at a substantial cost of dollar 38,925 per additional cure. With other estimates at baseline, MVA remained more cost-effective than D&C until the efficacy of MVA was < 82% or the cost of D&C was < dollar 240.
Conclusion:
MVA is the most cost-effective strategy for managing AEP and would be appropriate in settings in which resources are limited. D&C remains a reasonable strategy; however, one must spend dollar 38,925 per additional cure. In the United States, MVA would save dollar 779 million per year relative to D&C.
