ACOG Committee Opinion no. 450: Increasing use of contraceptive implants and intrauterine devices to reduce unintended pregnancy.

High unintended pregnancy rates in the United States may in part be the result of relatively low use of long-acting reversible contraceptive (LARC) methods, specifically the contraceptive implant and intrauterine devices. Top-tier reversible methods share the characteristic of requiring a single act of motivation for long-term use, eliminating adherence and user-dependence from the effectiveness equation. According to the World Health Organization's evidence-based Medical Eligibility Criteria for contraceptive use, LARC methods have few contraindications, and almost all women are eligible for implants and intrauterine devices. Because of these advantages and the potential to reduce unintended pregnancy rates, LARC methods should be offered as first-line contraceptive methods and encouraged as options for most women. To increase use of LARC methods, barriers such as lack of health care provider knowledge or skills, low patient awareness, and high upfront costs must be addressed.
