One hundred and sixty-seven women gave birth before arrival at the hospital during a six-year period in the Göteborg area. Most of these women had given birth before. The actual delivery most often started at term during the night, proceeded normally but rapidly and the neonatal outcome was good. Sixty-two per cent of the women delivered at home. Complicated lacerations or major hemorrhages were uncommon. The distance to the delivery ward was one of the risk factors for prehospital delivery. This is important to take into consideration in the ongoing process of centralizing the delivery clinics. Basic knowledge in obstetrics is mandatory for the ambulance personnel, as well as regular observation visits to the delivery ward and practice in birth simulators.
