Use of the inserter was found to be safe, with high fundal placement in 82% of cases. Complete expulsion occurred in 7.5% of cases and partial expulsion was detected in 10%, comparable with rates in other studies using standard IUD insertion techniques. Further study and use of the dedicated inserter may reveal increased convenience and reduced risk of infection among users and could improve acceptability of postpartum IUD provision among providers.

Objective: To evaluate the delivery-to-insertion interval for copper postpartum intrauterine devices (PPIUDs). Methods: Secondary analysis of two related studies at five academic sites in India from March 2015 to July 2016. IUDs were inserted within 48 hours of vaginal delivery. Women (n=560) were grouped by whether they underwent postplacental (≤10 minutes) or immediate (>10 minutes) insertion. Outcomes were complete expulsion at the 6-8-week follow-up (primary), and IUD-to-fundus distance, as assessed by postinsertion ultrasound (secondary). Results: Overall, 93 (16.6%) women received a postplacental PPIUD and 467 (83.4%) received an immediate PPIUD. Complete expulsion at follow-up was 3.2% (n=3) in the postplacental and 7.5% (n=35) in the immediate postpartum group (P=0.176; difference in proportions, 4.3%; 95% confidence interval, −2.0 to 8.1). Distance from the fundus did not differ between the two groups (P=0.107); high fundal placement (≤10 mm from the internal endometrial verge) was achieved for most women. Conclusion: The present data challenge previous guidance on the timing of PPIUD insertion. The 10-minute insertion window is a barrier to uptake and should be reassessed for inclusion in service delivery guidelines. A flexible interval would accommodate the multiple post-delivery tasks of providers and increase access to PPIUD.
