ObjectiveTo reach consensus between care providers and childbearing women about the midwife's relevant and appropriate domains and elements to support transition to motherhood.MethodsA modified web‐based Delphi study was conducted in Flanders (Belgium). After performing a systematic literature review, searching the grey literature and an online poll, a set of 79 items was generated. In two rounds, the items were presented to an expert panel of (1) care providers from various disciplines providing services to childbearing women and (2) to pregnant women and postpartum women up to 1‐year postpartum. Consensus was defined when 70% or more of the experts scored ≥6, 5% or less scored ≤3, and a standard deviation of ≤1.1.FindingsIn the first Delphi round, 91 experts reached consensus on 24 items. Seventeen round one items that met one or two consensus objectives were included in round two and were scored by 64 panel experts, reaching consensus on three additional items. The final 27 items covered seven domains: attributes, liaison, management of care from a woman‐centred perspective, management of care from the midwife's focus, informational support, relational support, and the midwife's competencies.ConclusionThe shared understanding between childbearing women and care providers shows that the midwife's transitional support is multifaceted. Our findings offer midwives a standard of care, criteria, guidance, and advice on how they can support childbearing women during transition to motherhood, beyond the existing recommendations and current provision of transitional care.
