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

The 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.
