Adolescent Long-Acting Reversible Contraceptive Use, Same-Day Insertions, and Pregnancies Following a Quality Initiative.

Objective: To compare long-acting reversible contraceptive (LARC) use, pregnancy rate, and same-day LARC insertion among adolescents before and after a Kaiser Permanente Northern California quality initiative.

Methods: A 2016 Kaiser Permanente Northern California initiative aimed to increase adolescent LARC access. Interventions included patient education resources, electronic protocols, and insertion training for pediatric, family medicine, and gynecology providers. This study examined a retrospective cohort of adolescents aged 15-18 years who used contraception before (2014-2015, n = 30,094) and after (2017-2018, n = 28,710) implementation. Contraceptive types included LARC (intrauterine device or implant), injectable, and contraceptive pill, patch, or ring. We reviewed a random sample of LARC users (n = 726) to identify same-day insertions. Multivariable analysis examined the effects of year of provision, age, race, ethnicity, LARC type, and counseling clinic.

Results: Preintervention, 12.1% of adolescents used LARC, 13.6% used injectable, and 74.3% used pill, patch, or ring. Postintervention, the proportions were 23.0%, 11.6%, and 65.4%, respectively, with the odds of LARC provision of 2.57 (95% confidence interval (CI) 2.44-2.72). The pregnancy rate decreased from 2.2% to 1.4% (p < .0001). Higher rates of pregnancy were observed with injectable contraception and in Black and Hispanic adolescents. Same-day LARC insertion rate was 25.1% without significant variation post intervention (OR 1.44, 95% confidence interval 0.93-2.23). Contraceptive counseling in gynecology clinics increased the odds of same-day provision, while non-Hispanic Black race lowered odds.

Discussion: A multifaceted quality intervention was associated with a 90% increase in LARC use and a 36% decrease in teenage pregnancy rate. Future directions may include promoting same-day insertions, targeting interventions in pediatric clinics, and focusing on racial equity.
