Abstract
OBJECTIVE: Our objective was to compare continuation and complication rates of subdermal etonogestrel implants and intrauterine devices (IUDs) using Medicaid insurance claims. STUDY DESIGN: We performed a retrospective cohort study using insurance claims data for 15- to 44-year-old subjects receiving implants or IUDs from 2012 to 2015 in a Medicaid managed care organization in Washington, DC, and Maryland. We performed a planned Kaplan-Meier survival analysis for long-acting reversible contraceptive (LARC) continuation, defined as the absence of a claim for LARC removal, during periods of continuous insurance plan enrollment. RESULTS: Three thousand one hundred three subjects received 1335 implants and 1970 IUDs, with implants more common than IUDs among subjects 15-19 years old (rate ratio=2.42), and implants less common than IUDs for subjects 20-44 years old (rate ratio=0.54). Implants had higher continuation rates at 1 year than IUDs (81.0% vs. 76.7%, p=.01). The difference was larger among subjects 25 to 44 years old (84.1% vs. 79.3%, p=.03) compared with subjects 15 to 19 years old (89.5% vs. 86.8%, p=.09) and subjects 20 to 24 years old (75.7% vs. 73.2%, p=.44). Claims for potential complications were similarly uncommon for both implants and IUDs (8.09% vs. 6.95%, p=.65), as were claims for pregnancies prior to LARC removal (0.82% vs. 0.86%, p=.86). CONCLUSION: Among a sample of 15- to 44-year-old Medicaid recipients, both implants and IUDs had high continuation rates and low complication rates; however, implants were slightly more likely than IUDs to remain in use 1 year after insertion. IMPLICATIONS: Among 15- to 44-year-old Medicaid recipients, both etonogestrel implants and IUDs have high continuation rates and low complication rates at 1-year postinsertion; however, implants are slightly more likely than IUDs to remain in use at 1 year.
