Anesthesiologist Assistants Across the US
Anesthesiologist assistants (AAs) work alongside anesthesiologists to provide safe and effective anesthesia care to patients. As highly trained healthcare professionals, anesthesiologist assistants practice in many places across the US to deliver high-quality anesthesia services 1.
Anesthesiologist assistants are highly trained non-physician anesthesia care providers who work under the supervision of licensed anesthesiologists 2. They undergo extensive education and training, typically completing a bachelor’s or master’s degree, followed by a specialized anesthesia assistant program accredited by the Commission on Accreditation of Allied Health Education Programs (CAAHEP). Upon graduation, AAs must pass a rigorous national certification exam administered by the National Commission for Certification of Anesthesiologist Assistants (NCCAA) to become certified and licensed to practice 3. The NCCAA consists of commissioners representing the American Society of Anesthesiologists, the American Academy of Anesthesiologist Assistants, certified anesthesiologist assistants, and doctors 4.
The role of anesthesiologist assistant originated during the 1960s, when three anesthesiologists were concerned with the shortage of anesthesiologists in the US. The result of this anesthesia workforce analysis was to initiate the concept of team care and to define a new mid-level anesthesia practitioner who would work under a supervising anesthesiologist. The new role of the anesthesiologist assistant thus critically alleviated the shortage of anesthesiologists 4.
In modern-day clinical practice, AAs are responsible for assisting anesthesiologists in administering anesthesia to patients before, during, and following surgical procedures. They play a crucial role in assessing patients’ preoperative health status, obtaining informed consent, and developing individualized anesthesia care plans. During surgery, AAs monitor patients’ vital signs, administer anesthesia medications, and adjust anesthesia levels as needed to ensure patient comfort and safety 3.
In addition to their clinical duties, AAs also perform various tasks to support the anesthesia team and enhance workflow efficiency. They may assist with the placement of invasive monitoring devices, such as arterial lines or central venous catheters, and manage anesthesia equipment and supplies in the operating room. Furthermore, AAs collaborate with other members of the surgical team to coordinate patient care, communicate important information, and respond to emergent situations during surgery 3.
The scope of practice for anesthesiologist assistants varies across the US due to differing state regulations and institutional policies. Not all states currently recognize AA licensure. However, in general, though AAs work under the supervision of anesthesiologists, they are trained to perform many tasks independently, allowing anesthesiologists to focus on more complex cases and critical decision-making. AAs are trained to administer anesthesia under direct supervision, meaning an anesthesiologist is physically present in the operating room and available to provide immediate assistance if needed 3.
Across the US, anesthesiologist assistants are employed in a variety of healthcare settings, including hospitals, surgical centers, and academic medical centers. AAs may specialize in specific areas of anesthesia practice, such as cardiac anesthesia, pediatric anesthesia, or pain management, depending on their interests and career goals.
AAs continue to be essential healthcare professionals who play a crucial role in providing safe and effective anesthesia care. With their advanced education, training, and clinical skills, anesthesiologist assistants contribute significantly to the delivery of high-quality anesthesia services across various healthcare settings in the US, and as the demand for anesthesia services continues to grow, they will remain an essential part of healthcare.
