Immediate postabortion initiation of levonorgestrel implants reduces the incidence of births and abortions at 2 years and beyond

Abstract

Objectives: The aims of this study were to compare immediate postabortion uptake of recently subsidized (no-cost) levonorgestrel-releasing implants with already available intrauterine and shorter-acting methods and to compare the incidence of subsequent pregnancies (ending in birth or abortion) within 2 years. Study design: Retrospective chart review of 4698 women attending a New Zealand public hospital abortion clinic over 2 years (2010-2012) to describe postabortion contraceptive choice, with follow-up via clinic and national births records to assess subsequent pregnancies at 12, 24, 36, and 48 months. Results: Twenty percent of the cohort (934/4698) received an implant, 26% an intrauterine method (927 copper intrauterine device, 301 levonorgestrel-releasing intrauterine system [LNG-IUS]), and 54% chose other shorter-acting methods (2536/4698). Method choice was significantly associated with age, ethnicity, and pregnancy history (p
