Public Health Registries: Immunizations

This is the onboarding page for immunizations. Onboarding refers to the testing and validation process that providers and public health programs engage in prior to ongoing submission of production data from electronic health record technology (EHRT). This page contains information on the Division of Public Health (DPH) Wisconsin Immunization Registry (WIR), including:

  • Technical capacity to receive data
  • Resource/administrative capacity and queue prioritization
  • Information required to register with the program
  • Detailed onboarding checklist

Technical capacity and specifications

WIR is capable of receiving immunization data electronically from providers Electronic Health Record (EHR) technology standards and specifications. WIR is capable of accepting the specific standards required to meet the 2015 Edition CEHRT definition [the HL7 Version 2.5.1: Implementation Guide for Immunization Messaging, Release 1.5 (October 2014) (PDF)].

Providers presently have two options to submit immunization data to public health:

  • Electronically send immunization data directly to WIR.
  • Electronically send immunization data to WIR via the Wisconsin Statewide Health Information Network (WISHIN).

Regardless of which transmission path is used, any provider newly onboarding to WIR or upgrading an existing interface to WIR for immunization data submission must conform to the HL7 2.5.1 standards.

Resource capacity and prioritization

DPH has limited resource capacity to test with and onboard data exchange partners.

DPH prioritizes immunization testing for all potential and existing data exchange partners. DPH is currently prioritizing the onboarding and testing process based on some of the following criteria (in no particular order):

  • Organization type (clinic, hospital, health department, pharmacy, etc.)
  • Number of locations/facilities
  • Data volume
  • Participation in Vaccines For Children (VFC) or Vaccines for Adults (VFA) programs
  • Organization’s participation in Promoting Interoperability
  • General upgrade of the interface, whether due to new EHR system or sending additional data elements

Prioritization is subject to change depending on DPH staff capacity and funding availability. Each prioritization criterion carries a different weighted value.

  8. Technical (EHR vendor) contact name, phone number, and email address
  9. Are you a federally qualified health center (FQHC)?
  10. Are you a local or Tribal health department or state partner agency?
