Anesthesiologists must complete an ACGME-accredited program, while anesthesiologist assistants must complete a CAAHEP-accredited program.


What Is the Difference in Supervised Care Models Between Anesthesiologists and Anesthesiologist Assistants?

The primary difference in supervised care models between anesthesiologists and anesthesiologist assistants is the level of clinical decision-making authority and responsibility for patient safety protocols. Anesthesiologists have professional autonomy and are responsible for the medical direction and oversight of anesthesiologist assistants. Anesthesiologist assistants are subject to the scope of practice regulations and collaborative practice agreements that are established by the supervising anesthesiologist. Anesthesiologists may delegate tasks to AAs, but the level of supervision required varies depending on the task. Direct supervision is required for certain tasks, while indirect supervision is allowed for others. In addition, anesthesiologists must be present on-site for certain procedures. Anesthesiologists and anesthesiologist assistants are both subject to quality assurance measures and continuing education requirements.


How Do Clinical Responsibilities Differ Between Anesthesiologists and Anesthesiologist Assistants?

However, CRNAs may have more job opportunities and career advancement opportunities than an anesthetist. Additionally, CRNAs may have lower professional liability insurance coverage than an anesthetist. The exact salary difference between an anesthetist and a CRNA will vary depending on the individual’s experience, location, and other factors.


Common Mistakes And Misconceptions

  1. Mistake: An anesthesiologist and anesthesiologist assistant are the same.

    Explanation: An anesthesiologist is a medical doctor who specializes in administering anesthesia to patients before, during, and after surgery or other medical procedures. An anesthesiologist assistant (AA) is a health care professional who works under the supervision of an anesthesiologist to provide patient care services related to anesthesia administration.
  2. Mistake: An AA can administer anesthesia without the supervision of a physician.

    Explanation: AAs must always work under the direct supervision of a licensed physician when providing patient care services related to anesthesia administration.
  3. Mistake: AAs have fewer educational requirements than physicians do for practicing medicine in general and specifically for administering anesthesia.

    Explanation: Both AAs and physicians must meet rigorous educational standards set by their respective governing bodies in order to practice medicine safely and effectively; however, physicians typically have more extensive training due to their higher level of education required for licensure as well as additional clinical experience gained through residency programs prior to entering practice independently as a physician specialist such as an anesthesiologist or surgeon.
