WISH Query: Injury-Related Emergency Department Visits (2016+)

(Data Updated January 2024)

This module provides data on the injury-related ED visits of Wisconsin residents from 2016 through the most recent available year of data. This data subset includes visits with any ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) diagnosis or external-cause code related to injury (see Technical Notes for more detail).

Step 1. Select "treated and released only" or "all visits."

We recommend the "Treated and Released ONLY" filter (the default selection) because it prevents counting a health care visit more than once. Patients transferred to hospitals for inpatient stays or those who died while in the ED are not included. This keeps the effects of injury from appearing artificially high. Selecting "ALL visits" will show the total volume of visits that EDs experience due to injury, including those visits that resulted in a transfer to inpatient hospitals or death in the ED.

Step 2. Select a measure of ED visits

This is the observed count of visits.

This is the observed rate and is displayed as the number of visits per 100,000 residents. Please use this rate when describing injury among your population of interest. This rate should not be used to compare different populations or time periods to each other as we have not adjusted these rates to account for differences in age composition across populations.

We recommend that you select age-adjusted rates when making comparisons between two populations (for example, Southern Region injury rates compared to Northern Region injury rates), or two different time periods (for example, 2016 injury rates compared to 2018). Age-adjustment accounts for differences in age composition across populations and time. We use the Standard U.S. Population for Year 2000 for age-adjustment.

Rank is based on number of ED visits and is not inclusive of all injuries. Injury cause categories in this option are mutually exclusive (see Technical Notes). If this option is selected, Steps 3, 7 and 8 will be skipped.

Step 3. Select ONLY ONE option from the list below.

The specific injury options listed below do not include ALL possible injury causes or manners. These options are also NOT mutually exclusive (for example, a motor vehicle injury may also be classified as a traumatic brain injury). There are nine possible diagnosis fields and two external cause of injury fields (e-codes) that can be coded for each visit and determine injury classification. One visit can be classified as multiple injury types below.

OR choose one of the following:

OR choose one of the following methods of self-harm injury (not inclusive of all methods; more than one method could have been used):

OR choose one of the following manners of TBI injury (not inclusive of all manners):

OR choose one of the following types of MVT injury (not inclusive of all types):

Step 4. Choose Area of Patient's Residence

Hold down the control (Ctrl) key to select multiple counties, regions, or regional trauma council areas.

Note: To see results for individual areas, choose "Geographic Area" as a ROW variable or COLUMN variable in Step 7 or 8 below.

See the region map, urban and rural map, or regional trauma advisory council map.

Step 5. Choose Year(s)

Choose the year in which the patient was discharged.

Note: WISH suppresses counts in cells that are less than 5 to comply with data privacy guidelines. Combine data years to increase cell counts.

Step 6. Choose Age, Sex, Race, and Ethnicity (Optional)

Rates will not be provided for "Two or More Races" or "Unknown" race. Due to changes in the reporting form, there was a larger number of missing and inconsistent race information from some facilities in the first quarter of 2018. Race information for this year should be reviewed with caution (especially when comparing to previous and later years) (see Technical Notes for more detail). 
Rates will not be provided for Unknown ethnicity.

Step 7. Choose a Row Variable

Row Variable Note: cannot be used with a "Ranked Causes" query.

Step 8. Choose a Column Variable (Optional)

Column Variable Note: cannot be used with a "Ranked Causes" or "Age-adjusted Rates" query.
