Prescriptive Authority – Are Pharmacists “Write”?




Drugs and Clinical Trials CategoryPharmacists are integral members of the health care team in the US. The profession is composed of highly-educated, well-trained health-care providers. Pharmacists promote themselves as “drug experts” for good reason: the four-years of education required to obtain the Doctor of Pharmacy (PharmD) degree encompasses the etiology, pathophysiology, clinical manifestations, prevention, and management of human disease states. Pharmacists study the clinical application of pharmacology, biopharmaceutics, pharmacokinetics, therapeutics, adverse drug reactions, laboratory data, and drug information to the management of disease states. This training enables pharmacists to identify and prevent drug interactions, plan patient evaluation of drug-related problems and recommend changes in pharmaceutical care plans, and evaluate and interpret pharmaceutical data.

PharmacistStill, these drug experts are not granted prescriptive authority under state or federal laws. Of course, physicians, osteopaths, dentists, and veterinarians have long-standing authority and experience in writing medication orders and prescriptions. In most states, these practitioners are granted full prescribing rights to any medication available, whether or not it falls within the scope of his or her practice. Each state governs its own laws regarding the prescriptive authority of more specialized practitioners, including podiatrists, nurse practitioners, and physician assistants. In some states, these practitioners have broad prescribing powers, while other states limit the type or schedule of medication allowed to be prescribed, or require strict collaborative practice agreements with physicians. Yet, almost no state allows pharmacists to prescribe or manage medication therapy outside the strict bounds of tightly controlled protocols for relatively routine medications.

Nurse practitioners and physician assistants have fought long legal battles to change the regulations governing their practice and their prescriptive authority. As more legislation is poised to expand their role further in many states, these groups are exploring the opportunity for almost completely autonomous practice. These groups focus on education and training as part of their battle for professional independence, and do not take their prescriptive authority lightly. These practitioners emphasize the need for continued education as part of their expanding role, and it has paid off, as patients accept their role as prescribers freely and believe the practitioners are knowledgeable about medications.

Still, pharmacists are the profession with the most education and experience in drug therapy. Expanded prescriptive authority for pharmacists would have benefits in cost and safety for the public. Pharmacists already govern the dispensing of some medications in a quasi-prescriptive role. Such “behind the counter” medications require pharmacists to consult with patients prior to the sale of medications that do not require a prescription, but do necessitate some level of supervision by a health care provider. The pharmacist is required to assess a patient for medical history, current medications, and drug allergies before dispensing the medication. Many professional groups advocate for an expanded “pharmacist-only” class of over-the-counter medications to increase the public’s access to medications.

Several studies have shown positive outcomes when pharmacists are directly involved in the prescribing, dispensing, and managing patients’ medication therapies. Many test cases have allowed pharmacists to independently manage therapy for diabetes, and overall improvement in patient’s glycemic control was seen when pharmacists were afforded prescriptive authority. Further, a reduction in costs and use of health care resources was seen, since diabetes-related complications were diminished. Favorable outcomes were also achieved when pharmacists took a lead role in the prescription and management of medications to treat chronic pain patients. The patients were effectively treated and costs were reduced when pharmacists were allowed prescriptive authority.

Barriers do exist to pharmacists’ prescriptive authority. Among the most significant include workload and time demands, particularly in today’s busy community pharmacy settings. A busy pharmacy counter or drive-through does not provide a safe or appropriate arena for discussing medication management. Further, most insurance providers do not compensate pharmacists for providing any sort of medication management service and providing clinical care is expensive. However, the expanding clinical role of pharmacists in hospital, long term care, and outpatient settings increase the opportunity for medication therapy management programs in which pharmacists are integral providers of effective health care. Even in a community pharmacy, pharmacists are accessible to the public and they are poised to assess and counsel patients more easily than any other health care provider.

Pharmacists are well-trained and well-educated medical professionals with richly-developed clinical judgment and scientific skills that are unparalleled by any other medical profession. Pharmacists need to fulfill their potential as drug experts and increase the value and access of quality health care to the public. The profession of pharmacy — and the public — should challenge the notion that pharmacists merely count pills and demand that they be directly involved in the prescription and management of medication therapy.
