Initiation of Postpartum Contraception by 90 Days at a Midwest Academic Center

Introduction: Contraception is a critical component of addressing the health needs of women in the postpartum period. We assessed contraception initiation by 90 days postpartum at a large, academic medical center in the Midwest.

Methods: In this retrospective cohort study, 299 charts were randomly sampled and 231 were analyzed from deliveries between May 1 to July 5, 2018. Contraceptive method, maternal demographics, and obstetric characteristics at hospital discharge were collected, as well as contraceptive method at the postpartum follow-up appointment. Methods and strata of contraception were categorized as follows: 1) highly effective methods (HEM) defined as sterilization, intrauterine device, or implant, 2) moderately effective methods (MEM) defined as injectable contraception, progestin-only pills, and combined estrogen/progestin pills, patches, and rings, and 3) less effective methods (LEM) defined as condoms, natural family planning, and lactational amenorrhea. Women lost to follow-up who had initiated a HEM or injectable contraception were coded as still using the method at 90 days. We used logistic regression to identity factors associated with HEM use.

Results: Of the 231 included patients, 118 (51%) received contraception before hospital discharge and 166 (83%) by 90 days postpartum. Postpartum visits were attended by 74% (171/231) of patients. Before hospital discharge, 28% (65/231) obtained a HEM and 41% (82/200) were using a HEM by 90 days postpartum. Patients obtaining HEM or injectable contraception before hospital discharge attended a follow-up visit less often than those who did not receive HEM before discharge (RR = 0.68, 95% CI: 0.54 - 0.86, p ≤ 0.01).

Conclusion: When readily available, many women will initiate contraception in the postpartum period. Health systems should work to ensure comprehensive access to contraception for women in the postpartum period.
