Early IUD insertion after medically induced abortion

There is insufficient evidence on the continuation, safety and acceptability of immediate insertion of the intrauterine device (IUD) after medical abortion. The objective of the present study was to evaluate clinical outcomes of early IUD insertion, compared with those of delayed IUD insertion, following medical abortion.

Women undergoing medical abortion with mifepristone and misoprostol up to 49 days' gestation and opting for Copper T 380A IUD contraception underwent early (5-14 days after mifepristone) or delayed insertion (3-4 weeks after mifepristone). The primary outcome measure was 6 month IUD continuation rate after medical abortion. Secondary outcome measures included user acceptability and safety.

Between October 2015 and October 2016, post-medical abortion IUD insertion was performed in 120 eligible women fulfilling the inclusion and exclusion criteria. There was no statistically significant difference in the continuation rates of the early and delayed IUD insertion groups at 6 months (76.7 versus 83.3%, p = .75). The 6 month IUD expulsion rates were 6.7 and 3.3% in the early and delayed insertion groups, respectively (p = .56). There were 10 (16.7%) removals in the early and eight (13.3%) in the delayed insertion groups (p = .77). Level of satisfaction with postabortal IUD use was comparable in both groups. Adverse events were rare and did not differ significantly between the two groups.

We demonstrated high continuation rates, safety and acceptability of early IUD insertion after medical abortion.
