Cooperation between midwives and doulas in the context of perinatal care - a integrative review of qualitative and quantitative studies

•The doula is a member of the interdisciplinary team that provides maternity care.•Identifying strategies which enhance collaboration between midwife and doulas has the potential to prop up the maternity system.•Cooperation between midwives and doulas constitutes an important element in the quality of perinatal care. A doula is a person who provides support to women in the perinatal period without providing medical services. During childbirth, the doula becomes a member of the interdisciplinary team. This integrative review aims to analyse the nature of the cooperation between doulas and midwives, its efficiency and challenges and ways of strengthening this cooperation. A structured integrative review of empirical and theoretical studies written in English was conducted. The literature search included MEDLINE, Cochrane, Scopus, ProQuest, Science Direct, Web of Science, and Embase Health Source: Nursing/Academic Edition databases. The analysis included papers published in 1995–2020. Dedicated documents were searched for different combinations of terms and standard logical operators. A manual search of the studies was included for additional references. Twenty-three articles from 75 full-text records were analysed. Three main themes emerged. (1) doulas are needed to prop up the system (2) barriers in collaboration between midwives and doulas; and (3) how cooperation between midwives and doulas can be strengthened. None of the articles referred directly to the impact of collaboration between midwives and doulas on the quality of perinatal care. This is the first review to analyse the impact of collaboration between midwives and doulas on the quality of perinatal care. Ensuring adequate collaboration between doulas and midwives requires effort from both of these professional groups and the health care system. However, such collaboration is supportive for birthing women and the perinatal care system. Further research in terms of the impact of this collaboration on the quality of perinatal care is needed.
