What it does
Summary by the , the Legislature's nonpartisan drafting office. It's their wording, not ours.
This bill provides that physician assistants and advanced practice nurse prescribers who are not employed by a local health department but who provide services without compensation for the programs and services provided by a local health department are, for the provision of those services, state agents of the Department of Health Services in certain circumstances for certain legal purposes and protections. For example, under the bill, if a physician assistant or certified advanced practice nurse prescriber who is considered a state agent of DHS is a defendant in any action or special proceeding because of acts they committed within the scope of their agency, any judgment as to damages and costs entered against them shall be paid by DHS.
Further, this bill provides that physician assistants and advanced practice nurse prescribers may be selected by a school district or a local health department to supervise an immunization program and issue orders for the administration of immunizations that are in accordance with written protocols issued by DHS. If the physician assistant or advanced practice nurse prescriber is not an employee of the school district or local health department, receives no compensation for his or her services as supervisor of the immunization program, and acts in accordance with written protocols issued by DHS, he or she is a state agent of DHS for the same legal purposes and protections as described above.
