Cost effectiveness of contraceptives in the United States

Background: The study was conducted to estimate the relative c perspective cost effectiveness of contraceptives in the United States from a payer's perspective. Methods: A Markov model was constructed to simulate costs for 16 contraceptive methods and no method over a 5-year period. Failure rates, adverse event rates and resource utilization were derived from the literature. Sensitivity analyses were performed on costs and failure rates. Results: Any contraceptive method is superior to "no method". The three least expensive methods were the copper-T intrauterine device (IUD) (USS647). vasectomy (USS713) and levonorgesurel (LNG)-20 intrauterine system (IUS) (USS930). Results were sensitive to the cost of contraceptive methods, the cost of an unintended pregnancy and plan disenrollment rates. Conclusion: The copper-T IUD, vasectomy and the LNG-20 IUS are the most cost-effective contraceptive methods available in the United States. Differences in method costs, the cost of in unintended pregnancy and time horizon are influential factors that determine the overall value of a contraceptive method. (C) 2009 Elsevier Inc.
