Assembly Bill No. 645
CHAPTER 273

An act to add Section 1797.161 to the Health and Safety Code, relating to emergency medical services.

[ Approved by Governor October 03, 2025. Filed with Secretary of State October 03, 2025. ]

LEGISLATIVE COUNSEL'S DIGEST


AB 645, Carrillo. Emergency medical services: dispatcher training.
Existing law, the Emergency Medical Services System and the Prehospital Emergency Medical Care Personnel Act (act), establishes the Emergency Medical Services Authority, which is responsible for the coordination of various state activities concerning emergency medical services (EMS). The act authorizes a county to develop an EMS program by designating a local EMS agency. Existing law also requires the Commission on Emergency Medical Services to review and approve regulations, standards, and guidelines to be developed by the authority. Existing law generally makes a violation of the act a misdemeanor.
This bill would require, by January 1, 2027, a public safety agency that provides “911” call processing services for emergency medical response to provide prearrival medical instructions to “911” callers requiring medical assistance, including, among other things, airway and choking medical instructions for infants, children, and adults and administration of naloxone for narcotics overdoses. The bill would require prearrival medical instructions to be approved by the local EMS agency medical director and implemented consistent with the medical protocols and procedures adopted by the public safety agency. By expanding the scope of a crime, and to the extent that the bill would create new duties for a public safety agency, the bill would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that with regard to certain mandates no reimbursement is required by this act for a specified reason.
With regard to any other mandates, this bill would provide that, if the Commission on State Mandates determines that the bill contains costs so mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
Vote: MAJORITY Appropriation: NO Fiscal Committee: YES Local Program: YES

The people of the State of California do enact as follows:


SECTION 1.

Section 1797.161 is added to the Health and Safety Code, to read:

1797.161.

(a) By January 1, 2027, a public safety agency that provides “911” call processing services for emergency medical response shall provide prearrival medical instructions to “911” callers requiring medical assistance, including, at a minimum, all of the following:
(1) Airway and choking medical instructions for infants, children, and adults.
(2) Automatic external defibrillator (AED) and CPR instructions for children and adults.
(3) Childbirth.
(4) Bleeding control and hemorrhage.
(5) Administration of epinephrine by auto-injector for suspected anaphylaxis.
(6) Administration of naloxone for suspected narcotics overdoses.
(b) A public safety agency may satisfy the requirements of subdivision (a) by contracting with another public safety agency that provides prearrival medical instructions.
(c) Prearrival medical instructions developed pursuant to subdivision (a) or (b) shall be approved by the local EMS agency medical director pursuant to subdivisions (c) and (d) of Section 1797.223 and implemented consistent with the medical protocols and procedures adopted by the public safety agency.
(d) This section does not require a public safety agency to update its policies and procedures if the public safety agency already provides prearrival medical instructions through emergency medical dispatch or other means and those instructions have been approved by the local EMS agency medical director.
(e) A public safety agency dispatching peace officers to the scene of an emergency shall not constitute call processing services for emergency medical response for purposes of this section, even though the peace officers may administer first aid and CPR pursuant to Section 1797.183.
(f) This section shall not be construed to alter, modify, abridge, diminish, enlarge, or constrain the authority’s ability to adopt guidelines or regulations for emergency medical dispatch, including dispatcher training, under existing law, including, but not limited to, Sections 1797.103 and 1797.107.
(g) This section does not supersede Section 1797.201, 1797.223, 1798.6, or 1798.8, or Section 53110 of the Government Code.

SEC. 2.

No reimbursement is required by this act pursuant to Section 6 of Article XIII B of the California Constitution for certain costs that may be incurred by a local agency or school district because, in that regard, this act creates a new crime or infraction, eliminates a crime or infraction, or changes the penalty for a crime or infraction, within the meaning of Section 17556 of the Government Code, or changes the definition of a crime within the meaning of Section 6 of Article XIII B of the California Constitution.
However, if the Commission on State Mandates determines that this act contains other costs mandated by the state, reimbursement to local agencies and school districts for those costs shall be made pursuant to Part 7 (commencing with Section 17500) of Division 4 of Title 2 of the Government Code.
