Women's perceptions and experiences of severe maternal morbidity - A synthesis of qualitative studies using a meta-ethnographic approach

Background
Maternal mortality is a relatively rare event in high-income countries and some middle-income countries. There is however a rising trend in the overall rate of severe maternal morbidity in many of these countries due to the increasingly complex obstetric and medical needs of women who become pregnant. With the aim to identify how women's experiences of health services following severe maternal morbidity could be improved, we explored women's perceptions and experiences of severe maternal morbidity (defined as major obstetric haemorrhage, severe preeclampsia, eclampsia, HELLP syndrome, critical care unit admission) by synthesising evidence from qualitative studies.

Methods
A systematic search of the literature was conducted using multiple databases, including MEDLINE, PsycINFO, EMBASE, CINAHL, British Nursing Index (BNI), Web of Science and Scopus, using predetermined search strategies. Studies were selected based on pre-defined inclusion and exclusion criteria. The methodological quality of selected qualitative studies was assessed using relevant CASP appraisal tools. Evidence synthesis was undertaken using meta-ethnography. The synthesis involved three steps: (1) ascertaining how studies were related or dissimilar through comparison; (2) translating one study's findings into another and (3) synthesis of the translation.

Findings
12 studies met inclusion criteria. Synthesis of these studies showed that women's experiences of severe maternal morbidity can be broadly categorised into three areas: experiencing the event of severe maternal morbidity, the immediate reaction to the event (physical experience, perception/interpretation of their situation, and emotion), and the aftermath (either a negative or positive experience), which are all interconnected. Women's experiences of severe maternal morbidity may be influenced by other factors such as the individuals' personal characteristics, pre-existing health conditions, feeling safe within the care provided, availability and accessibility of high quality health care, and their wider social support networks. Importantly, women's perceptions and experiences of severe maternal morbidity could be compounded by inadequate clinical management and care.

Conclusions
An experience of severe maternal morbidity and its subsequent management are physically and emotionally distressing, conjuring negative feelings and emotions and possibly poor postnatal outcomes. Findings suggest the importance of ensuring that the safety and quality of intrapartum interventions and models of postnatal care are enhanced, to reduce or prevent subsequent implications of an acute medical event on women and their families.
