Regulating Pharmacist Clinical Services: Is Legal Silence Golden or Deafening?

In the United States, the scope of practice of pharmacists is determined primarily at the state level. Not all state laws expressly permit or prohibit pharmacists from providing certain services; in between is a grey area of legal silence. Does legal silence permit pharmacists to perform a service that is not specifically permitted, but not expressly prohibited? Point-of-care testing provides a useful case study in legal silence: there are 1536 pharmacies currently holding a CLIA-waiver to administer tests in states reporting that pharmacists are not expressly permitted to administer tests. Legal silence may even provide a better framework for pharmacy based testing as it is naturally inclusive of any point-of-care test and no laws need updated when a new test comes to the market. Other health professions navigate this legal silence by governing according to a "standard of care." Rather than specifying a list of services a health professional can or cannot provide in law, it provides a flexible framework for the health professional to provide any service that other similarly situated health professionals would provide in the same or similar situation. A standard of care regulatory framework should thus be the target of the pharmacy profession in order to advance patient care.
