This module provides data on the injury-related hospitalizations of Wisconsin residents during 1995-2012.
The data count inpatient stays, not individual patients. This means that patients transferred between hospitals, readmitted to a hospital for further treatment, or otherwise treated in more than one inpatient stay have more than one record. This does not affect the accuracy of statistics on hospital charges or hospital days.
The data before 2000 include only records from Wisconsin hospitals. Records for Wisconsin residents treated in most Minnesota hospitals from 2000 forward were added in December 2012; all Minnesota hospitals' reports are included for 2006 forward. A number of Wisconsin counties have 5% or more of their residents' injury hospitalizations in Minnesota hospitals, so counts and rates for those counties substantially changed with that update. The October 2013 revision drops non-Wisconsin residents from the module; this also may affect previous counts and rates.
The October 2013 revision also modifies categories of expected payer by breaking out workers' compensation cases and adding 'other government' sources to the 'other or unknown' category.
