Data Element TR33.1 Referring Hospital

Applicable to all classified trauma centers starting January 1, 2024 

Data element definition: The name of the facility that cared for the patient immediately before the patient arrived at your facility.

Note: The Wisconsin Trauma Data Dictionary is prepared, maintained and updated by the Wisconsin Department of Health Services and is published on the Department’s Trauma webpage.

Education and Clarification: In the example scenario of a patient arriving at Hospital A, is transferred to Hospital B, and is transferred to Hospital C, in the trauma registry, Hospital B would select Hospital A as their referring hospital. In addition, Hospital C would select Hospital B as their referring hospital.  A common error is that Hospital B will select itself as the referring hospital as the patient was transferred from their hospital to another hospital. A hospital cannot be its own referring hospital.
