Listed below are links for applications that may be useful to former HAN users.

Wisconsin Public Health Information Network (PHIN) Resources for Former HAN Users

  • Statewide and local public health alerting capacity
  • Directory of public health emergency preparedness and response partners
  • Secure document repository

Note: All of the following applications require an active PHIN user account (formally known as HAN user account) in order to login. Going forward, all new users will need to follow the registration process at the PHIN Registration Site.

Wisconsin EHDI - Tracking Referral and Coordination (WE-TRAC)

WE-TRAC supports the goals of the Wisconsin Sound Beginnings program and the national EHDI goals by providing a mechanism for the tracking and reporting of individual, hospital, and statewide aggregate hearing screening data.


Wisconsin Birth Defects Registry (WBDR)

The Wisconsin Birth Defect Prevention and Surveillance Program is responsible for implementing Wisconsin Statute 253.12 (exit DHS) which was enacted in May 2000. This statute calls for the establishment of a confidential birth defects registry comprised of birth defects found in children from birth to two years of age who are diagnosed or treated in Wisconsin by a physician, pediatric specialty clinic or hospital. Reportable conditions occur prior to or at birth and require medical/surgical intervention or interfere with normal growth and development.
