A system and method for aggregating and providing subscriber medical record information to medical units. The system includes an ICE medical record server that stores a plurality of medical records of respective subscribers. When a subscriber is being attended by a medical unit, the medical unit using a communication device sends an identification number to the server. In response, the server sends the subscriber's medical record to the communication device. The communication device may populate a medical form with the information and display it for use in diagnosing and treating the subscriber. The medical unit may annotate the medical form to document the on-going emergency, and upload it to a professional medical record server, which may provide the information to a medical facility to which the subscriber will be transported. The ICE and/or professional medical record servers may perform statistical analyses of the information in their respective databases for the purpose of performing symptomatic surveillance and other public health analyses.
