What a pharmacist may initiate under a protocol

One state lets a pharmacist start or adjust a drug regimen without a new prescription, but only inside a written protocol built by a named group, only for a patient a physician has already seen, and only with notice back within a day.

The reservation the exception sits inside

California starts from a prohibition rather than a permission, which is the right place to read the exception from.

Except as otherwise provided in its pharmacy chapter, it is unlawful for any person to manufacture, compound, furnish, sell, or dispense a dangerous drug or dangerous device, or to dispense or compound a prescription of a prescriber, unless they are a pharmacist under that chapter.

The same section defines the yardstick those acts are measured by. Accepted standard of care means the degree of care a prudent and reasonable pharmacist licensed under the chapter, with similar education, training, experience, resources, and setting, would exercise in a similar situation.

That definition is unusually careful about context. It names resources and setting alongside education and training, which means the standard is not read the same way in a hospital and in a retail counter.

This is all licensure law, and it applies inside the accountability structure the same chapter builds. A pharmacy must have a board-approved pharmacist-in-charge who is responsible for the pharmacy's compliance with all state and federal laws and regulations pertaining to the practice of pharmacy.

Reading in that order matters because it settles what the exception is an exception to. The chapter does not begin by describing what a pharmacist may do and then add limits; it begins by reserving a set of acts to pharmacists and then names the narrow circumstances in which one of them may be initiated without a fresh prescription from a prescriber.

What "authorising the initiation of a prescription" means

California uses a specific phrase for what a pharmacist does here, and it is not the same phrase used for prescribing.

Notwithstanding any other law, a pharmacist may authorise the initiation of a prescription under four named sections of the chapter, and may otherwise provide clinical advice, services, information, or patient consultation, if a set of conditions is met.

Those conditions are cumulative. The clinical advice, services, information, or patient consultation must be provided to a health care professional or to a patient or a patient's agent; the pharmacist must have access to prescription, patient profile, or other relevant medical information for the purpose of patient and clinical consultation and advice; that access must be secure from unauthorised access and use; and the pharmacist must provide the service or activity consistent with the accepted standard of care.

The access condition is the one that constrains where this can happen. A pharmacist who cannot see the patient's prescription record, profile, or other relevant medical information does not meet the second condition, whatever else is in place.

Only one of the four named routes is described below. This article covers the protocol route in the section devoted to it, and makes no claim about what the other three permit, because those sections were not read.

The settings and the procedures

The protocol route is not a general community pharmacy authority. The statute lists the settings it operates in before it lists what may be done.

A pharmacist may perform the listed procedures or functions as part of the care provided by a health care facility, a licensed home health agency, a licensed correctional clinic, a licensed clinic in which there is physician oversight, a provider who contracts with a licensed health care service plan with regard to the care of that plan's enrollees, or a physician, in accordance with the policies, procedures, or protocols of that entity.

The procedures themselves are four. Ordering or performing routine drug therapy-related patient assessment procedures including temperature, pulse, and respiration; ordering drug therapy-related laboratory tests; administering drugs and biologicals by injection pursuant to a prescriber's order; and initiating or adjusting the drug regimen of a patient.

The fourth is the substantive one, and it is heavily qualified. Initiating or adjusting the drug regimen is done pursuant to a specific written order or authorisation made by the individual patient's treating prescriber, and in accordance with the policies, procedures, or protocols of the entity.

The statute then narrows it again. Adjusting the drug regimen does not include substituting or selecting a different drug, except as authorised by the protocol.

What the protocol itself must contain

The protocol is not a document one party writes. The section says who develops it and sets a floor for its contents.

The policies, procedures, or protocols shall be developed by health care professionals, including physicians, pharmacists, and registered nurses, and shall at a minimum do all of a listed set of things.

They must require that the pharmacist function as part of a multidisciplinary group that includes physicians and direct care registered nurses, and that group determines the appropriate participation of the pharmacist and of the direct care registered nurse.

They must require that the medical records of the patient be available to both the patient's treating prescriber and the pharmacist, and they must require that the procedures to be performed by the pharmacist relate to a condition for which the patient has first been seen by a physician.

That last requirement is the clearest boundary in the section. The protocol route operates downstream of a physician encounter about that condition, not instead of one.

The final minimum requirement is written as an exception, and reading the exception backwards is the quickest way to see the structure. Except for procedures or functions provided by a health care facility, a licensed correctional clinic, a licensed clinic in which there is physician oversight, or a provider contracting with a licensed health care plan regarding that plan's enrollees, the protocol must require the procedures to be performed in accordance with a written, patient-specific protocol approved by the treating or supervising physician.

The veto, the clocks and the qualification

Three further limits sit around the route, and each of them is short enough to be missed.

The prescriber holds a veto. A patient's treating prescriber may prohibit, by written instruction, any adjustment or change in the patient's drug regimen by the pharmacist.

Two twenty-four-hour notice duties run in parallel and are worded differently. Where a pharmacist initiates a drug regimen under the fourth procedure, the pharmacist shall provide written notification to the patient's treating prescriber, or enter the appropriate information in an electronic patient record system shared by the prescriber, within twenty-four hours.

The other clock attaches to the patient-specific protocol requirement. Any change, adjustment, or modification of an approved pre-existing treatment or drug therapy shall be provided in writing to the treating or supervising physician within twenty-four hours.

The pharmacist must also be qualified for the role before performing anything under the section. Prior to performing any procedure authorised by it, a pharmacist shall have either successfully completed clinical residency training or demonstrated clinical experience in direct patient care delivery.

That qualification requirement is individual rather than institutional, which is a useful way to close the reading. The protocol licenses an activity within a setting; the residency or direct patient care experience licenses the person carrying it out, and a protocol that satisfies every content requirement does not authorise a pharmacist who has met neither of those two conditions.

Key takeaways

Frequently asked questions

Can a pharmacist start a drug regimen without a new prescription in California?

Under the protocol section read here, a pharmacist may initiate or adjust the drug regimen of a patient pursuant to a specific written order or authorisation made by that individual patient's treating prescriber, and in accordance with the policies, procedures, or protocols of the named setting. It is not an open authority: the order or authorisation from the treating prescriber and the protocol are both preconditions.

Does that let a pharmacist swap the drug?

The statute addresses that directly and narrowly. Adjusting the drug regimen does not include substituting or selecting a different drug, except as authorised by the protocol. Substitution is therefore a protocol question rather than something the general adjustment authority carries with it.

Where does this apply?

The section lists the settings: as part of the care provided by a health care facility, a licensed home health agency, a licensed correctional clinic, a licensed clinic in which there is physician oversight, a provider contracting with a licensed health care service plan regarding that plan's enrollees, or a physician. It operates in accordance with the policies, procedures, or protocols of that entity.

Who writes the protocol?

Not one profession alone. The statute requires the policies, procedures, or protocols to be developed by health care professionals including physicians, pharmacists, and registered nurses. It further requires the pharmacist to function as part of a multidisciplinary group including physicians and direct care registered nurses, with that group determining the appropriate participation of the pharmacist and the direct care nurse.

Does a physician have to have seen the patient first?

For this route, the protocol must require it. Among the minimum contents of the protocol is a requirement that the procedures to be performed by the pharmacist relate to a condition for which the patient has first been seen by a physician. The protocol must also require the patient's medical records to be available to both the treating prescriber and the pharmacist.

What has to be reported back, and when?

Two things, each within twenty-four hours. Where a pharmacist initiates a drug regimen, the pharmacist must provide written notification to the treating prescriber or enter the information in an electronic patient record system shared by the prescriber. Separately, any change, adjustment or modification of an approved pre-existing treatment or drug therapy must be provided in writing to the treating or supervising physician. The treating prescriber may also prohibit any adjustment by written instruction.
