Frequency of Prenatal Care Visits: A Core Outcome Set for Prenatal Care Schedules.

Abstract

Objective: The aim of this study is to develop a core outcome set for the frequency and modality of prenatal care visits. Material and Methods: A consensus development study was conducted in the United States with participants, including 31 health care professionals, 12 public policy members or public health payers, and 18 public members, representing 24 states. A modified Delphi method and modified nominal group technique were utilized. Results: Twenty-one potential core outcomes were developed by combining the outcomes reported in three systematic reviews that evaluated the frequency of prenatal care visits or modality of prenatal visit type (e.g., in person, telemedicine, or hybrids of both). Eighteen consensus outcomes were identified from the Delphi process, following which 10 maternal and 4 neonatal outcomes were agreed at the consensus development meeting. Maternal core outcomes include maternal quality of life; maternal mental health outcomes; the experience of maternity care; lost time; attendance of recommended visits; unplanned care utilization; completion of the American College of Obstetricians and Gynecologists-recommended services; diagnosis of obstetric complications-proportion and timing; disparities in care outcomes; and severe maternal morbidity or mortality. Neonatal core outcomes include gestational age at birth, birth weight, stillbirth or perinatal death, and neonatal intensive care unit admissions. Conclusions: The core outcome set for the frequency and modality of prenatal visits should be utilized in forthcoming randomized controlled trials and systematic reviews. Such application will warrant that in future research, consistent reporting will enrich care and improve outcomes. Clinical Trial Registration number: 2021.
