Abstract

The current presentation of contraception pregnancy rates fails to address long-term planning or dual method use. This work fills that gap by creating a presentation that deals with both important issues. Framing pregnancy rates beyond one year is important because individuals intend to use contraception beyond just that one year. Including dual methods is also important because of its low theoretical pregnancy rate, and 15% of contraception users take this approach.

Further, future studies may benefit contraception users by including pregnancy rates for dual methods instead estimating them. This estimated calculation for the typical use of dual methods may violate assumptions within prediction models. Researchers should also gain accuracy by differentiating between simultaneous and alternating dual-method users because this classification yields different pregnancy rates. Finally, researchers should reconsider coding dual-method users as single method users. This practice artificially lowers the pregnancy rate for primary methods.
