Abstract
Background
The study was conducted to estimate the relative 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) (US$647), vasectomy (US$713) and
levonorgestrel (LNG)-20 intrauterine system (IUS) (US$930). 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 an
unintended pregnancy and time horizon are influential factors that determine the overall
value of a contraceptive method.
