ical decision making. This article focuses on collaboration between the mid
wife and the birthing woman and also discusses the collaborative relationsh
ip between midwives and obstetric consultants. A home birth cast: study ill
ustrates the interactions among the midwife, the woman. and the medical sys
tem. These critical relationships provide structure for safe, effective cli
nical practice in planned home birth when practice boundaries are not defin
ed by institutional walls. (C) 2000 by the American College of Nurse-Midwiv
