It is logical that birth centre outcomes are and will always be the same as hospital birth outcomes. Women who leave home are consciously leaving the safety of their home because they are under the misconception that the dangers of birth justify leaving the safety of their home. Leaving home releases higher levels of fear hormones, such as norepinephrine and ATP, and of course exposes the mother, fetus and newborn to unfamiliar and the potentially hostile bacteria of the strange environment. When we are home and the doors are locked, we are more relaxed and our unconscious brains can function better which promotes a faster and easier birth. Being home and having lower levels of stress hormones released serves to reassure the fetus, which prevents the fetal distress detected at about 20% of hospital and birth center births. The practitioner physically has the door key to the birth center and the birth center is for her convenience, not the birthing woman. If the woman had the door key and was encouraged to lock out whomever she wanted, as she does at home, that might influence outcomes at birth centers.
