The bill requires health care settings to develop and implement workplace violence prevention plans and establishes procedures for committee development, implementation, monitoring, investigation, and reporting. If a health care setting has an existing safety committee under RCW 49.17.050 or a workplace violence committee with employee-elected members equal to or exceeding employer-selected members, that committee must develop, implement, and monitor the plan. Plans must address security and physical features, staffing and lone-worker mitigation, job design and equipment, first aid and emergency procedures, incident reporting, employee training and implementation strategy, unit/shift/security risk analyses, and processes to assist employees affected by violent acts. Health care settings must consider guidance from the Department of Health, DSHS, L&I, federal OSHA, Medicare, and accrediting organizations and must comprehensively review and update plans at least once per calendar year. The bill also requires every workplace violence incident to be timely investigated, with investigations documenting date, time, location, nature of conduct and harm, responses and remediation, and, if applicable, a comparison of actual to planned staffing levels. Health care settings must report to the committee identified in RCW 49.19.020(1)(b) at least quarterly (critical access hospitals twice per year), providing deidentified summaries of required data (per RCW 49.19.040 and HIPAA), analyses of systemic causes, and recommendations for plan and practice changes. Legally, the act adds a new section to chapter 49.19 RCW and amends RCW 49.19.020, creating procedural requirements for prevention planning, investigation, and reporting; it does not, in the provided text, create a new crime or change penalties. The extracted text does not supply definitions for key terms such as "health care setting," "workplace violence," or "timely investigation," nor does it include enforcement mechanisms, penalties, or effective date language. RCW 49.19.040 is cited for required data to be summarized, but its contents are not included here.

If enacted, health care employers would need to create and keep a written workplace violence prevention plan that addresses security, staffing and lone-worker risks, job design and equipment, emergency and first-aid responses, incident reporting and training, unitand shift-specific risks, and support for employees affected by violence. Existing safety committees or a balanced workplace violence committee would be tasked with developing, implementing, and monitoring the plan, reviewing it at least once a year, investigating every workplace violence incident in a timely way (including noting staffing levels at the time), and sending regular deidentified reports with incident summaries, systemic cause analysis, and recommendations to the committee named in RCW 49.19.020; most facilities must report quarterly, while critical access hospitals report at least twice a year. The groups most affected are health care facilities, their safety or workplace violence committees, and employees who will need new training and possibly new security or response measures; facilities can expect added administrative work, investigation and reporting duties, and likely costs for training, security, and remediation actions. Reports must comply with HIPAA deidentification rules and planners must consider guidance from state and federal health and labor agencies, but the text provided does not define key terms like which settings qualify as a "health care setting," what counts as "workplace violence," how quickly investigations must occur, or spell out enforcement, penalties, or effective dates, so the full scope and timing of obligations is unclear.
