At Good Samaritan Medical Center in Phoenix, Arizona, a group of perinatal nurses examined the potential for improving care for antepartum, high-risk pregnant women on restricted activities in their homes. An antenatal testing, mobile outpatient monitoring service was developed and implemented within three months. The goal is to reduce frequent admissions to the hospital caused by the interruption of bed rest for weekly and biweekly outpatient evaluation and monitoring. The service has resulted in reduced hospital admissions and improved patient awareness of the need for and adherence to activity restrictions.
