Why are women deciding against birth in alongside midwifery units? A prospective single-center study from Germany

For healthy women entering labor after an uneventful pregnancy, advantages of birth in midwife-led models of care have been demonstrated. We aimed to study the level of awareness regarding care in alongside midwifery units (AMU), factors involved in the decision for birth in obstetrician-led units (OLU), and wishes for care and concerns about birth in women registering for birth in OLU who would have been eligible for care in AMU.

Healthy women with a term singleton cephalic fetus after an uneventful pregnancy course booking for birth in OLU were prospectively recruited. Data were collected by questionnaire.

In total, 324 questionnaires were analyzed. One quarter (23.1%) of participants never had heard of care in AMU. Two thirds (64.2%) of women had made their choice regarding model of care before entering late pregnancy; only 16.4% indicated that health professionals had the biggest impact on their decision. One-to-one care and the availability of a pediatrician were most commonly quoted wishes (30.8 and 34.0%, respectively), and the occurrence of an adverse maternal or perinatal event the greatest concern (69.5%).

Although the majority of respondents had some knowledge about care in AMU, expressed wishes for birth matching core features of AMU and concerns matching those of OLU, a decision for birth in OLU was taken. This finding may be a result of lack of knowledge about details of care in AMU; additionally, wishes and concerns may be put aside in favor of other criteria.
