Key outcomes in childbirth: Development of a perinatal core outcome set for management of labor and delivery at or near term

Abstract

AbstractIntroductionConsistency and relevance of perinatal outcome measures are necessary basics for obstetric research, audit, and clinical counseling. Still, there is an unwarranted variation in reported perinatal outcomes, which impairs research synthesis, validity, and implementation, as well as clinical benchmarking and longitudinal comparisons. The aim of this study was to develop a short‐term perinatal (fetal and neonatal) Core Outcome Set to be used in research and quality assurance of management of labor and delivery at or near term.Material and methodsThe methods were guided by the Core Outcome Measures in Effectiveness Trials Initiative Handbook. The project was prospectively registered on July 2, 2020 in the Core Outcome Measures in Effectiveness Trials (COMET) data base (reference number 1593). A list of potential outcomes was created based on a systematic review of studies evaluating interventions for peripartum management at or near term (≥34 weeks of gestation), including decisions regarding timing and type of onset of labor, intrapartum care, and mode of delivery. The list was entered into a two‐round Delphi survey with predefined consensus criteria. Participants (n = 67) included clinicians, researchers, lay persons with experience of childbirth (patient representatives), and other stakeholders. A consensus meeting was held to reach a final agreement.ResultsResponse rates were 82.1% (55/67) and 92.7% (51/55) for the first and second Delphi rounds, respectively. In total, 17 outcomes were included in the final core outcome set, reflecting mortality, health or morbidity, including asphyxia, central nervous system status, infection, neonatal resuscitation and admission, breastfeeding and mother‐infant interaction, operative delivery due to fetal distress, as well as birthweight and gestational age. Two of these outcomes were suggested by patient representatives.ConclusionsThe Swedish Perinatal Core Outcome Set (SPeCOS) study involved a broad circle of relevant stakeholders and reached consensus on a minimal set of perinatal outcomes that should be collected and reported in a standardized way in all future studies on management of labor and delivery at or near term, regardless of the specific population or condition studied. This could improve obstetric research, evidence synthesis, uptake, implementation, and adherence, as well as clinical practice, audit, and comparisons in childbirth care.
