Use of contraceptive implants at 12 months in women who intended to undergo immediate versus delayed postpartum insertion following high-risk pregnancy

Objective To assess the correlation between the intention to undergo immediate versus delayed postpartum contraceptive implant insertion following high-risk pregnancy, and the proportion of utilization and adverse effects. Methods We conducted a retrospective cohort study of women who gave birth after a high-risk pregnancy (according to the criteria defined by the Society for Maternal-Fetal Medicine) and intended to use contraceptive implants. The participants were classified into two groups based on whether they underwent immediate or delayed insertion. The primary outcome was the proportion of utilization of contraceptive implants at 12 months postpartum. We performed multivariate analyses to determine the relationships between the timing of insertion, characteristics, and methods used. Results Of the 482 women classified as having high-risk pregnancies, 103 intended to use contraceptive implants (54 immediate and 49 delayed insertions). Women in the immediate group were more likely to use contraceptive implants than those in the delayed group at 6 (95.2% vs. 26.2%, P
