California doesn't have a statewide protocol.
Your right, they don't have a "statewide protocol" per-se, but they DO have a minimum and maximum scope of practice. The county medical directors essentially have a list of skills and medications to choose from. Anything outside of that can't be added without doing an approved study to prove the benefit and necessity.
The county I worked in fought tirelessly for years to get stuff added. It's a horrible system with way too much red-tape and politics to get through.
