ABSTRACT

Background:

Prenatal care, one of the most common preventive care services in the United States, endeavors to improve pregnancy outcomes through evidence-based screenings and interventions. Despite the prevalence of prenatal care and its importance to maternal and infant health, there are several debates about the best methods of prenatal care delivery, including the most appropriate schedule frequency and content of prenatal visits. Current U.S. national guidelines recommend that low-risk individuals receive a standard schedule of 12 to 14 in-office visits, a care delivery model that has remained unchanged for almost a century.

Objective:

In early 2020, to mitigate individuals’ exposure to the SARS-CoV-2 virus, prenatal care providers implemented new paradigms that altered the schedule frequency, interval, and modality (e.g., telemedicine) of how prenatal care services were offered. In this manuscript, we describe development of a core outcome set (COS) that can be used to evaluate the effect of the frequency of prenatal care schedules on maternal and infant outcomes.

Methods:

We will systematically review the literature to identify previously reported outcomes important to individuals who receive prenatal care and the people who care for them. Stakeholders with expertise in prenatal care delivery (i.e., patients/family members, healthcare providers, and public health professionals and policymakers) will rate the importance of identified outcomes in an online survey using a three-round Delphi process. A virtual consensus meeting will be held for a group of stakeholder representatives to discuss and vote on the outcomes to include in the final COS.

Results:

The Delphi survey was initiated in July 2022 with 71 stakeholders invited. A virtual consensus conference was conducted on October 11, 2022. Data is currently under analysis.

Conclusions:

More research about the optimal schedule frequency and modality for prenatal care delivery is needed. Standardizing outcomes that are measured and reported in evaluations of the recommended prenatal care schedules will assist evidence synthesis and results reported in systematic reviews and meta-analyses. Overall, this COS will expand the consistency and patient-centeredness of reported outcomes for various prenatal care delivery schedules and modalities, hopefully improving the overall efficacy of recommended care delivery for pregnant people and their families.
