DOH Emergency Care System Data Request Form

Thank you for your interest in requesting data from the Washington State Department of Health's Emergency Care System. WEMSIS is the Washington State data repository for EMS responses, while the Washington Trauma Registry is the data repository for patients admitted into the trauma system.

General data details to consider:

• Each record in WEMSIS pertains to a single response by an EMS unit. If you desire patient level data, be mindful that you may receive records from multiple EMS units dispatched to the same patient at a single incident. These records often do not share the same incident number but could be linked using patient and scene information.

• Each record in the Washington Trauma Registry pertains to a single admission to a licensed trauma facility in Washington State. If you desire patient level data, be mindful that you may receive records from multiple admissions of the same patient for a single trauma injury.

• Per RCW 70.168.090, data elements related to the identification of individual patient's, provider's and facility's care outcomes are considered confidential, and may require a data sharing agreement or approval from the Washington State Institutional Review Board (WSIRB). For information on the WSIRB review process, please visit Human Research Review Section | DSHS (wa.gov).
