The bill amends RCW 70.168.090, adds a new section to chapter 43.70 RCW, and creates a new statutory requirement that the (unnamed) department submit specified opioid overdose information from the Washington emergency medical services information system (WEMSIS) to the overdose detection mapping application program (ODMap). Beginning July 1, 2027, the department must transmit data for all fatal and nonfatal opioid overdoses reported to WEMSIS, and must submit for each EMS patient care report within 24 hours the date and time of the overdose, the latitude/longitude where the patient was initially encountered (with some departmental discretion on geolocation specificity), whether opioid overdose reversal medication doses were administered, and whether the overdose was fatal or nonfatal when initially encountered or during transport. The department must establish an API or similar process to allow near-time transfer, and the bill creates limits on use and disclosure: data submitted to or available through ODMap may not be used for law enforcement welfare checks, warrants, immigration enforcement, or criminal investigations of the treated individual, the department may not submit information that allows identification of an individual, and submission and access must be immediately terminated if the department determines prohibited uses or unauthorized federal access occur. The bill also amends RCW 70.168.090 to require the department to establish a statewide electronic EMS data system, adopt reporting rules for licensed ambulance and aid services, define data elements and secure transport methods by rule, include suspected drug overdoses in collected data for public health and outreach purposes, and require regional EMS and trauma care quality assurance programs (established by facilities authorized to provide trauma care levels I–III) to evaluate trauma care delivery, patient outcomes, and compliance; those quality assurance programs may also evaluate emergency cardiac and stroke care. The bill includes definitions for aid service, ambulance service, opioid, ODMap, and WEMSIS as used in these provisions. Separate provisions address actions arising from the department’s licensing or verification of ambulance or aid services, certification of medical program directors, and restriction or revocation of health care provider clinical or staff privileges, and specify that information identifying individual patients shall not be publicly disclosed without the patient’s consent. The extracted text does not identify the full name of “the department,” leaves one subsection mid-list and incomplete, and does not include any penalties, enforcement mechanisms, funding, or other implementation details that may appear elsewhere in the bill.

If enacted, Washington will require the health agency identified as "the department" to push near-real-time opioid overdose reports from the statewide EMS reporting system into the ODMap overdose mapping program starting July 1, 2027, with each EMS report sent within 24 hours. This will likely shift costs and work onto the department to build an interface and on licensed ambulance and aid services to ensure timely, consistent reporting of overdose events, locations (latitude/longitude), whether reversal drugs were used, and whether the overdose was fatal; regional trauma centers will also have new or clarified quality assurance duties. Because the law bars submitting information that could identify individuals and prohibits ODMap use for law enforcement, immigration, or criminal prosecutions, the department must put safeguards in place and may have to stop submissions immediately if misuse or unauthorized federal access is discovered, which could intermittently disrupt the overdose surveillance feed. Most affected are the department, EMS providers (ambulance and aid services), ODMap operators, and regional trauma care programs: the department gains a clear responsibility and potential technical and staffing costs to implement the data feed and rules; EMS providers must comply with tighter reporting expectations; ODMap will receive wider, faster data but face compliance constraints; and patients gain protections against public disclosure of identifying information without consent. The bill text leaves unclear which exact agency is "the department," how deidentification will be implemented in practice, and whether dedicated funding or penalties accompany these new duties, so some implementation details and fiscal impacts remain uncertain.
