Immediate Versus Interval Postpartum Use of the Levonorgestrel Contraceptive Implants: a Randomized Controlled Trial

Waiting until 6 weeks postpartum to initiate contraception puts women at risk for unintended pregnancy and short birth intervals. Short birth intervals of less than 18 months are associated with an increased risk of preterm delivery and low birth weight infants.

Subdermal implants are advantageous for the postpartum period because they are long-acting, reversible, and highly effective, and they do not contain estrogen or require intrauterine placement. In observational studies postpartum continuation rates have been shown to be greater than 95% after 6 months and 86-87% after 1 year in US populations. Implants are not routinely available during the immediate postpartum period in Uganda, and availability could improve the contraceptive method mix for postpartum women in that country. The results of this study may support increasing access to a form of immediate postpartum LARC (long acting reversible contraception) in a developing country.

This is a randomized, controlled trial of the association between immediate postpartum contraceptive implant placement and implant utilization at 6 months postpartum among women in Uganda. This study will compare the proportion of women using the Levonorgestrel contraceptive implant at 6 months after delivery in women randomized to insertion within 5 days of delivery (immediate insertion) or 6 weeks after delivery (delayed insertion). The study population is women who have a delivery at Mulago hospital in Kampala, Uganda and choose a contraceptive implant for postpartum contraception.

The investigators plan to enroll 202 women who are planning to receive a postpartum Levonorgestrel contraceptive implant after delivery to find out whether the timing of postpartum administration of the implant (prior to hospital discharge or 6 weeks after delivery) affects implant utilization, satisfaction with the implant, vaginal bleeding or breastfeeding.
