Anesthesiologist assistant

In the United States, anesthesiologist assistants - known in full as certified anesthesiologist assistants - are healthcare workers who work under the direction of licensed anesthesiologists to implement anesthesia care plans for a patient undergoing surgery. CAAs can only work within the anesthesia care team environment as described by the American Society of Anesthesiologists (ASA). All CAAs possess a baccalaureate degree (in any field with a focus on pre med sciences), and complete a didactic and clinical program at postgraduate level. CAAs are trained in the delivery and maintenance of anesthesia care as well as advanced patient monitoring techniques under the direct supervision of a physician anesthesiologist. The goal of CAA education is to guide the transformation of student applicants into competent health care practitioners who aspire to practice in the anesthesia care team.[1]

General description

Prior to acceptance into their respective graduate programs all anesthesiologist assistant students must possess an undergraduate degree. [2] The anesthesiologist assistant works under the medical direction of a physician anesthesiologist as a part of the anesthesia care team. Anesthesiologist assistants, under the direction of physician anesthesiologists, administer medications, IV fluids and blood products.[3]

Anesthesiologist assistants generally work in the hospital setting but can work at any location such as pain clinics, dental offices, and outpatient surgical centers. Anesthesiologist assistants work in all facets of surgical environments such as endoscopy, conscious sedation, abdominal surgery, orthopedic surgery, as well as cardiac surgery, neurosurgery, transplant surgery, and trauma surgery centers. Currently Certified Anesthesiologist Assistants are able to practice in sixteen states and Washington DC.[3] In each of these states, the anesthesiologist assistant falls under the regulatory authority and licensing of the State Board of Medicine.[3]

As of 2017 there are twelve anesthesiologist assistant training programs in the United States[4] all of which offer degrees at the Master’s level.[5] Approximately 97% of currently working anesthesiologist assistants hold a master's degree (some early anesthesiologist assistant graduates held bachelor's degrees). All newly credentialed and future anesthesiologist assistants must complete an accredited Master’s program for anesthesiologist assistants. Upon completion of the educational program, graduates must sit for a credentialing exam that is co-validated by the National Board of Medical Examiners and National Commission for Certification of Anesthesiologist Assistants. All anesthesiologist assistant programs are credentialed by the Commission on Accreditation of Allied Health Educational Programs (CAAHEP).[6]

History of the profession

In the 1960s, three anesthesiologists, Joachim S. Gravenstein, John E. Steinhaus, and Perry P. Volpitto, were concerned with the shortage of anesthesiologists in the country. These academic department chairs analyzed the spectrum of tasks required during anesthesia care. The tasks were individually evaluated based on the level of professional responsibility, required education and necessary technical skill. The result of this anesthesia workforce analysis was to introduce the concept of team care and to define a new mid-level anesthesia practitioner linked to a supervising anesthesiologist. This new professional - the Anesthesiologist Assistant or AA - had the potential to at least partially alleviate the shortage.

The chairmen's vision became reality in 1969 when the first AA training programs began accepting students at Emory University in Atlanta, Georgia, and at Case Western Reserve University in Cleveland, Ohio.Today these goals are still upheld: 10% of AAs choose to later go to medical school.[7][8]

Education

A master’s level education is required to train anesthesiologist assistants to collect patient data, assist in the evaluation of patients’ physical and mental status, document the surgical procedures planned, and administer the therapeutic plan for patient care that has been formulated by the anesthesiologist.[9] There are only eleven programs available for the Anesthesiologist Assistant master's degree in the United States. All programs are accredited by the Commission on Accreditation of Allied Health Education (CAAHEP).

To enroll in an AA program, candidates require a bachelors degree with a focus in pre medical sciences and have to obtain a minimum of eight hours of documented anesthesia exposure by observation in the operating room.[9][11] All programs require an entrance exam (either GRE or MCAT, MCAT preferred).[12][13][14]

Program lengths range from 24 to 28 months with didactic and clinical instruction.[9][11] Didactic training includes courses such as physiology, pharmacology, airway management, simulation laboratory, Basic Life Support (BLS) certification, Pediatric Advanced Life Support (PALS) certification, Advanced Cardiac Life Support (ACLS) certification, anatomy, monitoring, and applied principles and practices. In addition to class work, programs include 2000 to 2700 clinical hours per student.[15] Students gain preoperative, intra-operative and post-operative experience with a variety of patients in a variety of surgical settings.[9][11][12] In addition, each program may have additional educational experiences; for example, Nova Southeastern University provides students with courses on scientific research and publishing.[12] All programs must have at least one board-certified, licensed anesthesiologist serving as a director. Additionally, each AA program must be based at, or in collaboration with, a university that has a medical school.[3]

Certification

Graduates from an accredited educational program are eligible to take the initial certifying examination and can do so up to 6 months before graduating from the program. The certifying examination for anesthesiologist assistants is a written exam administered by the National Board of Medical Examiners (NBME), which is contracted by the National Commission for Certification of Anesthesiologist Assistants (NCCAA). Once successfully completed, the NCCAA will award a time-limited certificate to each candidate. In order to maintain certification, anesthesiologist assistants need to register for 40 hours of Continuing Medical Education (CME) every two years and successfully complete a Continued Demonstration of Qualifications (CDQ) examination every six years.[16][17]

Scope of practice

Anesthesiologist assistants are trained assistants who work under the direction of licensed physician anesthesiologists as integral members of the Anesthesia Care Team (ACT) .[18] The following list is obtained from the American Academy of Anesthesiologist Assistants (AAAA), which states anesthesiologist assistant responsibilities may include but are not limited to:[3]

  • Assist the Anesthesiologist by Administering the prescribed induction drugs, maintain and adjust appropriate anesthetic depth as directed of an Anesthesiologist, call the anesthesiologist for help when additional treatment is necessary.
  • Perform post-anesthesia rounds by documenting patient progress notes, collecting and recording case summaries.
  • Alert the Anesthesiologist and call for help when life-threatening situations arise, such as cardiac arrest, so that the Physician can treat with protocols established within BLS, ACLS, and PALS.

The AA scope of practice may differ slightly in relation to local practice, and is usually defined by the medically directing anesthesiologist, the hospital's clinical protocol procedures, the state’s board of medicine, and state regulations.

Employment

The American Medical Association (AMA) states that "AAs are most commonly employed in larger facilities that perform procedures such as cardiac surgery, neurosurgery, transplant surgery, and trauma care."[6] Studies by the AMA found entry-level salaries for 2006 Anesthesiologist Assistant graduates to be between $100,000 and $130,000 for the 40-hour work week plus benefits and consideration of on-call activity. They also found the high end of the salary range to be around $190,000 to $220,000 for experienced anesthesiologist assistants.[19] Salaries vary by region and individual employer.

Anesthesiologist assistants are currently able to work in sixteen states plus Washington, D.C. and the US territory of Guam either by licensure or through physician delegation. AAs are recognized by the federal government and are authorized to work at all Veteran Affairs hospitals using the TRICARE insurance program.[20]

Licensure defines the practice of AAs and is achieved through state law or by approval of the individual state board of medicine. Physician delegation is achieved through recognition of AAs by the state board of medicine or through statutes included in the state's medical practice act. The board of medicine affords Anesthesiologist's the right to delegate the responsibilities of their realm of practice to qualified individuals. Delegating authority requires that the physician remain ultimately responsible for the patient. In all states, the practice of anesthesiologist assistants is guided by the board of medicine. Any attempt to employ AAs under delegating authority should be made through the individual state's board of medicine.[3]

States where AAs practice through license and certification:[20]

  • Alabama
  • Colorado
  • District of Columbia
  • Florida
  • Georgia
  • Indiana
  • Kentucky
  • Missouri
  • New Mexico
  • North Carolina
  • Ohio
  • Oklahoma
  • South Carolina
  • Vermont
  • Wisconsin

States where AAs practice through physician delegation:

  • Michigan
  • Texas

In the U.S. federal government

Anesthesiologist Assistants are employed at Veteran Affairs (VA) and Department of Defense facilities under the TRICARE health system since Dec 22, 2006.[7]

The Veterans Health Administration Handbook 1123 on Anesthesia Service, includes the profession of anesthesiologist assistant as an allied health professional. Information in regards to required qualifications, coverage criteria, billing, and payment for Medicare services under the TRICARE program for anesthesiologist assistants is published by the Department of Health and Human Services.[21]

AA's are currently classified as GS-0601, General Health Science Series employees, as defined by The Handbook of Occupational Groups and Families from the U.S. Office of Personnel Management.[22]

gollark: And shouldn't it just do generalized "go mining", or risk going up and down a lot and wasting fuel?
gollark: But... are there really multiple ways to do necessary things to do what a player asks for?
gollark: I mean, that's kind of the opposite.
gollark: So why should some things get "priorities" or something? Shouldn't it just try and do whatever it has to do to do what the player wants in the order which minimizes cost?
gollark: Shouldn't it just do things as requested, instead of randomly doing whatever?
