Development and application of a large-scale disaster preparedness system in the perinatal field.

Objective: To introduce the Perinatal Early Assessment and Communication system for Emergencies (PEACE), a dedicated internet-based system for sharing maternal and newborn health information during large-scale disaster.

Methods: PEACE was developed by the Japan Society of Obstetrics and Gynecology (JSOG) to enable internet-based sharing of maternal and newborn support information between facilities and rescue teams in disaster areas. PEACE input rates during prefecture-scale disasters and in disaster drills were surveyed for two facility categories: centers for perinatal medical care (CPMs) and combined clinics + regional general hospitals.
