Women and healthcare providers' perceptions of a midwife-led unit in a Swiss university hospital: a qualitative study.

Background: The development of medical-led care in obstetrics over the past decades has contributed to improving outcomes for both mother and child. Although efficiency has improved in complex situations, unnecessary interventions are still practiced in low-risk pregnancies, contrary to international recommendations. A shift to a less interventionist model of care has encouraged many countries to review their policies on maternal health care and develop models such as the "midwife-led unit" (MLU) where the midwife plays a predominant role with a minimum of routine intervention.
