Key clinical point: Cesarean delivery was independently associated with missing strings and expulsion of an IUD placed after delivery.
Major finding: Among women who underwent postplacental copper IUD placement, missing strings were noted in 47.9% 34.2% of women at postpartum visits 1 and 2, respectively, and 8.9% experience expulsions by visit 2. Cesarean delivery was associated with a significantly increased risk of missing strings, but a decreased risk of IUD expulsion (adjusted risk ratios 6.21 and 0.24, respectively).
Study details: The data come from 705 women who underwent postplacental insertion of a copper T380A IUD. The women were assessed at postpartum visits at 45-90 days and again at 6-9 months.
Disclosures: The study received no outside funding. The researchers had no financial conflicts to disclose.
