Abstract
INTRODUCTION: Home births and births in midwife-led units and the associated potential risks are still being debated. An analysis of the quality of results of planned home births and births in midwife-led units which require intrapartum transfer of the mother to hospital provides important information on the quality of processes during births which occur outside hospital settings. The aim of this study was to analyze neonatal and maternal outcomes after the initial plan to deliver at home or in a midwife-led unit had to be abandoned and the mother transferred to hospital. MATERIAL AND METHODS: The method used was an analysis of data obtained from the Austrian Birth Registry. The dataset consisted of singleton term pregnancies delivered in the period from 1 January 2017 to 31 December 2021 (n = 286056). For the analysis, two groups were created for comparison (planned hospital births and hospital births recorded in the Registry as births originally planned as home births or births in midwife-led units but which required a transfer to hospital) and assessed with regard to previously defined variables. Data were analyzed using frequency description, bivariate analysis and regression models. RESULTS: In Austria, an average of 19% of planned home births have to be discontinued and the mother transferred to hospital. Home births and births in midwife-led units which require transfer of the mother to hospital are associated with higher intervention rates intrapartum, high rates of vacuum delivery, and higher emergency c-section rates compared to planned hospital births. Multifactorial regression analysis showed significantly higher risks of poorer scores for all neonatal outcome parameters (Apgar score, pH value, transfer rate). CONCLUSION: If a birth which was planned as a home delivery or as a delivery in a midwife-led unit fails to progress because of (possible) anomalies, the midwife must respond and transfer the mother to hospital. This leads to a higher percentage of clinical interventions occurring in hospital. From the perspective of clinical obstetrics, it is understandable, based on the existing data, that giving birth outside a clinical setting cannot be recommended.
