The immediate postpartum period is a favorable, safe, and effective time to provide long-acting reversible contraceptives, yet it is not available widely. We describe an innovative hospital-based approach to immediate postpartum long-acting reversible contraceptives that includes (1) an emphasis on multidisciplinary teambuilding and identification of champions, (2) a focus on the use of implementation science at every stage of the process to develop a systematic and replicable strategy, and (3) an imperative to apply a reproductive justice framework to immediate postpartum long-acting reversible contraceptive implementation. Our model was developed with the use of implementation science best practices. Implementation teams comprised of diverse stakeholders were formed and included champions to promote progress. Our team assessed the implementation context for immediate postpartum long-acting reversible contraceptives and used the findings to develop a readiness assessment for hospitals. A stage-based implementation checklist was then developed to outline necessary infrastructure to support an immediate postpartum long-acting reversible contraceptive initiative. A reproductive justice lens guided planning and implementation. The 3 innovative aspects of our implementation process resulted in a systematic, multidisciplinary, and culturally appropriate model for immediate postpartum long-acting reversible contraceptives that can be replicated across hospitals. Implementation teams and champions moved the work forward at each hospital, and 3 of the 5 participating hospitals moved beyond the exploration stage of implementation during the engagement. Patient education materials and provider training incorporated person-centered and reproductive justice frameworks. Our hope is to continue to partner with stakeholders to better understand how our efforts to support hospital provision of immediate postpartum long-acting reversible contraceptives can increase reproductive health equity rather than perpetuate disparity.
