PHC Hub (v. March 2018) User Guide

Introduction to PHC Hub

The primary purpose of PHC Hub (Public Health Connection Hub) is to establish connections (interfaces) to improve public health. PHC Hub facilitates the integration between healthcare provider systems and Immunization Information Systems (IIS) by managing HL7 message processing. PHC Hub can be integrated with either the IWeb application or WIR IIS.

PHC Hub receives inbound HL7 messages, extracts and validates the data, translates coded values, and updates the host system's database with patient and immunization data. In addition to supporting the standard inbound unsolicited HL7 message transaction, PHC Hub also supports a reciprocal batch interface where new patient immunization activity that may be unknown to the provider is returned using the original inbound connection. PHC Hub supports HL7 inbound query requests for patient immunization history. Both HL7 versions, 2.3.1 and 2.5.1, are supported. PHC Hub supports quality reporting and extensive customization of the field level message validation process.

PHC Hub is divided into the following areas:

Projects - Allows immunization registry staff and other connecting entities to organize and track interface progress.
Test - Allows vendors and EHR users to test HL7 messages in a controlled environment.
Imports - Controls how data for each interface is translated and verified before being accepted into the immunization registry, as well as controls incoming queries.
Exports - Controls how and when data is exported from the immunization registry.
Reports - Enables the immunization registry staff and EHR users to run and/or schedule reports to aid in monitoring the data imported and the data quality.
