Avoidability of maternal death in Mozambique: audit and retrospective risk assessment in 106 consecutive cases

A maternal mortality audit identified 106 cases of maternal death in Maputo (340 per 100 000 live births), caused by haemorrhage (31%), hypertensive diseases of pregnancy (15%), puerperal sepsis (12%) and septic abortion (9%). Puerperal uterine inertia (12%) and malaria (9%), respectively, were the most prevalent causes of direct and indirect maternal death. The maternal mortality audit analyses, indicated that health services research is fruitful in a more detailed, systematic study on maternal deaths at the community level wit ensuing analyses of avoidability aspects. Lack of transport and poor quality of antenatal and intrapartum care in peripheral maternity units implied that women with eclampsia, obstructed labor, post partum atonic haemorrhage and uterine rupture arrived late due to deficient transport.Shortage of blood and delay in access to operating theatre contributed significantly to fatal maternal outcome in several cases. The audit provided evidence that approximately 40% of the deaths would have been avoidable with existing resources. It is particularly significant that the analysis of antenatal cards revealed that only 30% had any high risk factors, implying that more than two thirds of women dying a maternal death are low risk women.
