BackgroundIn many low- and middle-income countries women are encouraged to give birth in clinics and hospitals so that they can receive care from skilled birth attendants. A skilled birth attendant (SBA) is a health worker such as a midwife, doctor, or nurse who is trained to manage normal pregnancy and childbirth. (S)he is also trained to identify, manage, and refer any health problems that arise for mother and baby. The skills, attitudes and behaviour of SBAs, and the extent to which they work in an enabling working environment, impact on the quality of care provided. If any of these factors are missing, mothers and babies are likely to receive suboptimal care.ObjectivesTo explore the views, experiences, and behaviours of skilled birth attendants and those who support them; to identify factors that influence the delivery of intrapartum and postnatal care in low- and middle-income countries; and to explore the extent to which these factors were reflected in intervention studies.Search methodsOur search strategies specified key and free text terms related to the perinatal period, and the health provider, and included methodological filters for qualitative evidence syntheses and for low- and middle-income countries. We searched MEDLINE, OvidSP (searched 21 November 2016), Embase, OvidSP (searched 28 November 2016), PsycINFO, OvidSP (searched 30 November 2016), POPLINE, K4Health (searched 30 November 2016), CINAHL, EBSCOhost (searched 30 November 2016), ProQuest Dissertations and Theses (searched 15 August 2013), Web of Science (searched 1 December 2016), World Health Organization Reproductive Health Library (searched 16 August 2013), and World Health Organization Global Health Library for WHO databases (searched 1 December 2016).Selection criteriaWe included qualitative studies that focused on the views, experiences, and behaviours of SBAs and those who work with them as part of the team. We included studies from all levels of health care in low- and middle-income countries.Data collection and analysisOne review author extracted data and assessed study quality, and another review author checked the data. We synthesised data using the best fit framework synthesis approach and assessed confidence in the evidence using the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach. We used a matrix approach to explore whether the factors identified by health workers in our synthesis as important for providing maternity care were reflected in the interventions evaluated in the studies in a related intervention review.Main resultsWe included 31 studies that explored the views and experiences of different types of SBAs, including doctors, midwives, nurses, auxiliary nurses and their managers. The included studies took place in Africa, Asia, and Latin America.Our synthesis pointed to a number of factors affecting SBAs’ provision of quality care. The following factors were based on evidence assessed as of moderate to high confidence. Skilled birth attendants reported that they were not always...
