The outcomes of women beginning labor at home, ultimately delivering at home, and the infants born at home were studied in order to determine the safety of home birth among expectant women choosing to be attended by a midwife licensed to practice by the state of Louisiana. Trends associated with those choosing home birth and the frequency of home birth were also analyzed. The study was conducted using retrospective records of clients accepted during the study years 1986- 2000. During the study years, the midwives began care on 284 women. Of those women, 225 delivered at home, 31 were transported to the hospital at some point, 7 voluntarily left the midwife’s care, and 20 were referred out for various reasons. The only cause of infant mortality in the home births was congenital anomalies. There were no maternal deaths or significant maternal morbidity. The years with the largest number of home births were 1997, 1998, and 1999 with 32, 35, and 32 births respectively. During these three
