WHA Information Center (WHAIC) has been collecting hospital, ASC and survey discharge data as authorized by the Wisconsin Department of Administration, since 2003 as defined by Chapter 153, Wisconsin Statutes.

Inpatient and outpatient data is collected quarterly through a secure, web-based tool known as WIpop to produce public use data sets, custom data sets and three annual publications.

In addition, all Wisconsin hospitals submit Annual, Fiscal, Personnel and Uncompensated Care survey data annually. Data collected from these surveys are used for trending, benchmarking, and other key statistics.
