Abstract: We 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 given sufficient training during their education or after they had begun clinical work. Also, inadequate staffing of facilities could increase the workloads of skilled birth attendants, make it difficult to provide supervision and result in mothers being offered poorer care. In addition, SBAs did not always believe that their salaries and benefits reflected their tasks and responsibilities and the personal risks they undertook. Together with poor living and working conditions, these issues were seen to increase stress and to negatively affect family life. Some SBAs also felt that managers lacked capacity and skills, and felt unsupported when their workplace concerns were not addressed. Possible causes of staff shortages in facilities included problems with hiring and assigning health workers to facilities where they were needed; lack of funding; poor management and bureaucratic systems; and low salaries. Skilled birth attendants and their managers suggested factors that could help recruit, keep, and motivate health workers, and improve the quality of care; these included good-quality housing, allowances for extra work, paid vacations, continuing education, appropriate assessments of their work, and rewards. Skilled birth attendants’ ability to provide quality care was also limited by a lack of equipment, supplies, and drugs; blood and the infrastructure to manage blood transfusions; electricity and water supplies; and adequate space and amenities on maternity wards. These factors were seen to reduce SBAs’ morale, increase their workload and infection risk, and make them less efficient in their work. A lack of transport sometimes made it difficult for SBAs to refer women on to higher levels of care. In addition, women’s negative perceptions of the health system could make them reluctant to accept referral. We identified some other factors that also may have affected the quality of care, which were based on findings assessed as of low or very low confidence. Poor teamwork and lack of trust and collaboration between health workers appeared to negatively influence care. In contrast, good collaboration and teamwork appeared to increase skilled birth attendants’ motivation, their decision-making abilities, and the quality of care. Skilled birth attendants’ workloads and staff shortages influenced their interactions with mothers. In addition, poor communication undermined trust between skilled birth attendants and mothers. Many factors influence the care that SBAs are able to provide to mothers during childbirth. These include access to training and supervision; staff numbers and workloads; salaries and living conditions; and access to well-equipped, well-organised healthcare facilities with water, electricity, and transport. Other factors that may play a role include the existence of teamwork and of trust, collaboration, and communication between health workers and with mothers. Skilled birth attendants reported many problems tied to all of these factors.

Plain-language summary: We included 31 studies conducted in Africa, Asia, and Latin America. Participants were skilled birth attendants including doctors, midwives, nurses, auxiliary nurses and their managers. Our synthesis pointed to several factors that affected skilled birth attendants’ provision of quality care. The following factors are based on evidence assessed as of moderate to high confidence. Skilled birth attendants reported that they sometimes had insufficient training during their education or after they had begun work. Where facilities lacked staff, skilled birth attendants’ workloads could increase, it could become difficult to provide supervision, and mothers could receive poorer care. In addition, skilled birth attendants did not always believe that their salaries and benefits reflected their tasks and responsibilities and the personal risks they undertook. Together with poor living and working conditions, these issues could lead to stress and affect skilled birth attendants' family life. Some skilled birth attendants felt that managers lacked capacity and skills, and they felt unsupported when their workplace concerns were not addressed. Possible causes of staff shortages included problems with hiring and assigning health workers to health facilities; lack of funding; poor management and bureaucratic systems; and low salaries. Skilled birth attendants and their managers suggested factors that could help recruit, keep, and motivate health workers, and improve the quality of their work; these included good-quality housing, allowances for extra work, paid vacations, continued education, proper assessments of their work, and rewards. Skilled birth attendants’ ability to provide quality care was also limited by a lack of equipment, drugs, and supplies; blood and the infrastructure to manage blood transfusions; electricity and water supplies; and adequate space and amenities on maternity wards.
