Background Indicators to evaluate progress towards timely access safe surgical, anaesthesia, and obstetric (SAO) care were proposed in 2015 by the Lancet Commission on Global Surgery. These aimed capture surgery, surgical workforce, volume, perioperative mortality rate, catastrophic impoverishing financial consequences of surgery. Despite being rapidly taken up practitioners, data points from which derive indicators not defined, limiting comparability across time or settings. We convened...

Introduction Despite ongoing maternal health interventions, deaths in Tanzania remain high. One of the main causes mortality includes postoperative infections. Surgical site infection (SSI) rates are higher low/middle-income countries (LMICs), such as Tanzania, compared with high-income countries. We evaluated impact a multicomponent safe surgery intervention hypothesising it would (1) increase adherence to safety practices, WHO Safety Checklist (SSC), (2) reduce SSI following caesarean...

Recent efforts to increase access safe and high-quality surgical care in low- middle-income countries have proven successful. However, multiple facilities implementing the same safety quality improvement interventions may not all achieve successful outcomes. This heterogeneity could be explained, part, by pre-intervention organizational characteristics lack of readiness facilities. In this study, we describe process developing content validating Safe Surgery Organizational Readiness Tool.The...

Postpartum hemorrhage (PPH) is the leading cause of maternal mortality in developing countries. While incidence PPH can be dramatically reduced by uterotonic use immediately following birth (UUIFB) both community and facility settings, national coverage estimates are rare. Most health systems have no indicator to track this, community-based measurements even more scarce. To fill this information gap, a methodology for estimating UUIFB was developed piloted four settings. The rapid estimation...

In 2009, the WHO introduced surgical safety checklist (SSC) as one of interventions for improving patient safety. The systematic use structured checklists during surgery has been shown to reduce perioperative morbidity and mortality.

Access to emergency obstetric care, including assisted vaginal birth and caesarean birth, is crucial for improving maternal childbirth outcomes. However, although the proportion of births by section has increased during last few decades, use declined. This particularly case in low- middle-income countries, despite an often being less risky than birth.
