The home uterine activity monitor (HUAM) is a device intended to provide early detection of preterm labor (PTL) in women at high risk of developing PTL and preterm birth (PTB). Usually, the individual is instructed to use the device daily for two 1-hour periods. After monitoring, the individual transmits the recordings by telephone modem link to a remote base station. Base station nurses not only facilitate transmission and analysis of the monitor tracings, they also maintain daily telephone contact with the individual to assess signs and symptoms and to provide advice and counseling.
The use of a home uterine monitor with or without associated nursing services is considered not medically necessary, and is not eligible for reimbursement. Clinical evidence supporting the use of home uterine activity monitoring to prevent preterm delivery is limited and conflicting. No ongoing clinical trials using this device have been identified.
