Overview of the Profession


What is an Anesthesiologist Assistant (AA)?

Anesthesiologist Assistants (AAs) are highly skilled health professionals who work under the direction of licensed anesthesiologists to implement anesthesia care plans.  AAs work exclusively within the Anesthesia Care Team environment as described by the American Society of Anesthesiologists (ASA).

AAs possess a pre-medical background, a baccalaureate degree, a graduate degree from a CAAHEP-accredited training program, and national certification from the NCCAA.

The American Academy of Anesthesiologist Assistants (AAAA) is the national professional organization for AAs. Additional information about the profession, advocacy, and events is available on their website.

AA Employment

Practice authorization for AA licensure or delegatory authority varies by state. AAs are most commonly employed in larger facilities that perform procedures such as cardiac surgery, neurosurgery, transplant surgery, and trauma care. This is due to the training in extensive patient monitoring devices, complex patients, and procedures emphasized in AA educational programs. However, AAs are used in hospitals of all sizes and assist anesthesiologists in a variety of settings and for a wide range of procedures.
