This module provides data on the injury-related emergency department visits of Wisconsin residents during 2002-2012.
The module includes only emergency department visits that resulted in the patient being released. It does not include emergency department visits that resulted in the patient being admitted as an inpatient in this or another acute-care hospital or another type of institution (these are in the Injury Hospitalizations Module) or dying in the emergency department (see Injury Mortality Module).
Records for Wisconsin residents treated in most Minnesota hospitals from 2002 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-related ED visits 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.
