Obstetric early warning system to predict maternal morbidity of pre-eclampsia, postpartum hemorrhage and infection after birth in high-risk women: a prospective cohort study.

Objective: The purpose of early warning systems is to detect deterioration of the patient and to enable timely intervention to prevent possible severe illness. The most common causes of maternal morbidity and mortality after birth are worsening pre-eclampsia, postpartum haemorrhage and puerperal infection. Our aim was to validate the accuracy of the obstetric early warning system and different physiological triggers to predict morbidity on the postnatal ward in high-risk women.

Routine Bedside Use of Obstetric Early Warning System in the Postnatal Ward to Identify Maternal Morbidity Among High-Risk Women.

Objective: Several authorities have recommended the use of an obstetric early warning system (OEWS) to prevent severe morbidity and mortality. Data on the accuracy of OEWS in different clinical settings and maternal populations are still scarce. Our aim was to validate OEWS to detect maternal morbidity among high-risk women in the postnatal ward.
