Under whose supervision do physicians' assistants provide patient care?

Physician assistants (PAs) operate under the supervision and instruction of a licensed physician, which is fundamental to their role within the healthcare system. This supervision is critical as it ensures that PAs practice within the scope of their training and adhere to established medical protocols. The physician remains responsible for the overall patient care, guiding the PA in diagnostic and treatment plans according to the patient's specific needs.

While PAs might collaborate with various healthcare professionals, including oncologists or registered nurses, their practice is primarily governed by the licensed physician's direct oversight. This structured supervision ensures that patient safety and care quality are maintained, as PAs work effectively within a team under the leadership of a physician who has the ultimate accountability for patient outcomes.
