This study is the first in the United Kingdom (UK) to look at how women and families from different backgrounds use ambulance services during the 'perinatal period' - through pregnancy, birth, and shortly after having a baby. The researchers want to understand whether all women have the same access to urgent and emergency maternity care, and whether there are differences in health outcomes for mothers and babies who use ambulance services. The study has two parts (called Work-Packages): Work Package One will look at data from women who were taken by ambulance to a Manchester University National Health Service (NHS) Foundation Trust (MFT) maternity unit during the perinatal period, compared with those who had a baby at MFT but were not taken there by ambulance. It will look at the differences between the two groups and their health outcomes. Work Package Two will look closely at the text written by paramedics within ambulance records for some women from Work Package One, especially those at increased risk of a poor outcome. The researchers will study what happened during their care journey and look for anything that happens repeatedly within the text to better understand their experiences. By combining the results from both work packages, the study aims to give a detailed picture of how different women access emergency maternity care and outcomes for themselves and their babies. This will help identify ways to improve services, especially for women who may face barriers to getting the care they need, helping to make sure that maternity care is safe, fair, and more effective for everyone.
Background: This study will be the first United Kingdom (UK)-based study to investigate access to ambulance services for women and families from diverse backgrounds during pregnancy, birth and early postpartum period. The study will explore relevant maternal and infant outcomes for families who seek help from the ambulance service to explore health disparities in accessing urgent and emergency care. Findings from this study will inform local and national policy aimed at reducing maternal and perinatal mortality and morbidity. This will contribute to the identification of access challenges experienced by seldom-heard women in a crucially important, but under investigated area of unscheduled urgent and emergency maternity care. Methods: A mixed methods approach including two work packages (WP). WP1 includes a retrospective comparative cohort study (WP1) to describe the characteristics of and outcomes for pregnant women and their neonates who are transferred via ambulance to Manchester University National Health Service (NHS) Foundation Trust (MFT) and those that are not. Descriptive statistics with comparative analyses will be presented. WP2 includes a qualitative framework analysis of a purposive sub-sample of routinely collected free-text digital records documented by paramedics for women who arrived at the unit via ambulance. Purposive sampling will be undertaken for women who are identified at an increased risk of poor maternal and/or neonatal outcomes following WP1 analyses. The patient journey will be mapped, and patient profiles constructed. An explanatory mixed methods approach will be undertaken for triangulation of data for insight. Discussion: The study aims to provide an in-depth understanding of access to emergency maternity care to allow investigation of opportunities for alternative clinical decision making and review of current service provision. This also helps to identify women with increased risk factors for accessing urgent and emergency care as a gateway to maternity services. This will help to address timely access to the most appropriate services, reducing risk factors for adverse maternity and neonatal outcomes and associated impact upon the emergency services. Findings will be used to inform local and national interventions for at risk populations who access ambulance services during pregnancy, birth, and early postpartum. Findings will also support system conversations around the reasons for seeking help from the ambulance service in the perinatal period and ways to improve access and care provisions for underserved communities.
