U.S. Department of Health and Human Services, Office of the Assistant Secretary for Preparedness and Response. (2014). HPP-PHEP 6.1: Information Sharing.

This list of Essential Elements of Information (EEI) can be used as a guide for emergency medical planners and responders. It asks for information regarding: the number of partners that reported requested EEI (which can be divided by the number that reported it); the type of exercise, event, or incident; the type and number of local partners that responded to the request; types of EEI requested; type of communication system used to make the request; and other related components. While this document does not track with current capabilities, it does contain valuable information sharing information.
