Facilitating the rapid sharing of overdose mapping information for overdose prevention.
SB 5933 creates a centralized system for rapidly sharing overdose data to improve public health responses. It requires Washington's Department of Health to submit near real-time data from emergency medical services (including location, opioid reversal use, and fatality status) within 24 hours of patient care reports, starting January 1, 2027. The system will help identify overdose hotspots and guide immediate interventions like outreach, public education, and treatment resources, while explicitly prohibiting the use of this data for law enforcement or individual identification. This affects ambulance services, aid providers, and the Department of Health, who must submit and manage the data under strict privacy safeguards. The bill aims to streamline collaboration across health and public safety agencies to address the opioid overdose crisis.

MINOR
The bill was renumbered from S-3690.1 to S-4555.1 and updated with committee referral and reading dates. The most significant substantive change is the modification of geolocation data requirements, which now allows the department to adjust precision based on whether an area is urban or rural rather than using a single standard for all locations. Additionally, a new clause was added to immediately terminate access to the mapping program if a federal agency accesses the data without authorization.
Scope change
The bill's scope regarding data collection precision was expanded to account for rural versus urban environments, while a new enforcement mechanism was added to protect against unauthorized federal access.
REQUIREMENT
Geolocation data precision requirements were changed from a single standard to a flexible standard allowing four decimal places in urban areas and at least two decimal places in rural areas, giving the department discretion to balance resource deployment with privacy.
ENFORCEMENT
A new provision mandates the immediate termination of the overdose detection mapping application program if any federal agency accesses the data without prior authorization.
TECHNICAL
The bill number was updated from S-3690.1 to S-4555.1, and the text was reformatted to reflect committee referral and reading dates.
