  • Description:
    The CDC Public Health Information Network (PHIN) is a national initiative to improve the capacity of public health to use and exchange information electronically by promoting the use of standards, defining functional and technical requirements. PHIN Communication and Alerting (PCA), one component o f PHIN, is a specification o f public health alerting capabilities, with an emphasis on interoperability of partners’ systems. Alerting in this context means the functionality necessary to manage time-critical information about public health events, send it in real time to personnel and organizations that must respond to and mitigate the impact o f these events, and verify and monitor delivery of this information. Systems that provide PCA functionality support these capabilities, integrate them with the organization’s other public health information systems and processes, and support interoperability with partners’ systems.

    PCA is not identical to, or a replacement for, the Health Alert Network (HAN). PCA is a technical specification for alerting. HAN is a public health program that performs alerting. Most organizations with HAN systems are in the process o f moving them toward compliance with the PCA specification.
