Longitudinal impact of a residency-based postplacental levonorgestrel intrauterine device insertion program: Expulsion rates in years 1, 2, and 3

Abstract

ObjectiveTo evaluate expulsion rates in the first 3 years of an academic postplacental levonorgestrel intrauterine device (LNG-IUD) insertion program. Study designRetrospective case series, January 2016 to December 2018. We measured LNG-IUD expulsion rates by 12 weeks postpartum. ResultsOf 235 LNG-IUD insertions, in years 1, 2, and 3, expulsion rates were 11/39 (28%), 9/94 (10%), and 15/102 (15%) (p = 0.03). After vaginal delivery, manual insertion was associated with a higher expulsion rate than ring-forceps (10/28 [36%] vs 17/105 [16%], p = 0.04). ConclusionsLNG-IUD expulsion rates decreased after program year 1, suggesting program maturity may be associated with a lower expulsion risk.
