Provision of contraceptive implants in school-based health centers: A cost-effectiveness analysis.

OBJECTIVE

To evaluate the cost-effectiveness of providing contraceptive implants in school-based health centers (SBHCs) compared to the practice of referring adolescents to non-SBHCs in New York City.

STUDY DESIGN

We developed a microsimulation model of teen pregnancy to estimate the cost-effectiveness of immediate provision of contraceptive implants at SBHCs over a 3-year time horizon. Model parameters were derived from both a retrospective chart review of patient data and published literature. The model projected the number of pregnancies as well as the total costs for each intervention scenario. The incremental cost-effectiveness ratio was calculated using the public payer perspective, using direct costs only.

RESULTS

The health care cost of immediate provision of contraceptive implants at SBHCs was projected to be $13,719 per person compared to $13,567 per person for delayed provision at the referral appointment over 3 years. However, immediate provision would prevent 78 more pregnancies per 1000 adolescents over 3 years. The incremental cost-effectiveness ratio for implementing in-school provision was $1940 per additional pregnancy prevented, which was less than the $4206.41 willingness-to-pay threshold. Sensitivity analyses showed that the cost-effectiveness conclusion was robust over a wide range of key model inputs.

CONCLUSION

Provision of contraceptive implants in SBHCs compared to non-SBHCs is cost-effective for preventing unintended teen pregnancy. Health care providers and policymakers should consider expanding this model of patient-centered health care delivery to other locations.
