Mapping Long-acting Reversible Contraceptive Interventions to the Social Ecological Model: A Scoping Review

Long-acting reversible contraception (LARC) is one option for preventing unintended pregnancies and short interpregnancy intervals. Efforts to increase access to contraception may benefit from applying the social ecological model (SEM), a framework that considers individual, interpersonal, organizational, community, and policy influences on behavior. We aimed to summarize findings from interventions on LARC use and map interventions to SEM levels.

We conducted a scoping review of the 2010-2020 literature in PubMed/MEDLINE and Embase databases to summarize interventions that did and did not increase LARC use. Although increasing LARC use is not an appropriate goal from a reproductive autonomy standpoint, it is the stated goal of much of the research conducted to date and typically indicates an improvement in access. We mapped these interventions to SEM levels and categorized their strategies: cost support, patient counseling, administrative support, provider training, and other.

Of 27 interventions reviewed, 17 (63%) increased LARC use. We observed a greater proportion of interventions that increased LARC uptake among those with strategies implemented at policy (8/10 [80%]) or organizational (14/19 [74%]) SEM levels compared with interventions implemented at other SEM levels. When both individual and organizational SEM-level components were implemented, five of six interventions (83%) increased uptake. All five interventions with both organizational- and policy-level components increased LARC use. Among the 27 interventions, patient counseling (n = 12) and cost support (n = 12) were common strategies. Five of 12 interventions (42%) involving patient counseling and 11 of 12 (92%) involving cost support increased LARC use.

Organizational and policy SEM components and cost support strategies were most prevalent in interventions that increased LARC use. Future interventions to improve access to contraception, while respecting patient autonomy, could incorporate more than one SEM level.
