Nurse anesthetists have provided anesthesia care to patients in the United States for more than 150 years. Nurses first provided anesthesia on the battlefields of the American Civil War. During World War I, nurse anesthetists became the predominant providers of anesthesia care to wounded soldiers on the front lines.
The Certified Registered Nurse Anesthetist (CRNA/nurse anesthesiologist) credential came into existence in 1956 and in 1986 CRNAs/nurse anesthesiologists became the first nursing specialty accorded direct reimbursement rights from Medicare. In 2001, the Centers for Medicare & Medicaid Services (CMS) changed the federal physician supervision rule for nurse anesthetists to allow state governors to opt out of this facility reimbursement requirement.
Today, CRNAs/nurse anesthesiologists have full practice authority in every branch of the military and are the primary providers of anesthesia care to U.S. military personnel on the front lines, navy ships, and aircraft evacuation teams around the globe.
CRNAs/nurse anesthesiologists safely administer more than 58 million anesthetics to patients each year in the United States. As advanced practice registered nurses, they are among the nation’s most trusted professions according to Gallup. Nurses have topped Gallup’s Honesty and Ethics list for 22 consecutive years and are ranked second in U.S. News & World Report’s 2024 “Best Health Care Jobs” report.
CRNAs/nurse anesthesiologists practice in every setting in which anesthesia is delivered: traditional hospital surgical suites and obstetrical delivery rooms; critical access hospitals; ambulatory surgical centers; ketamine clinics; the offices of dentists, podiatrists, ophthalmologists, plastic surgeons, and pain management specialists; and U.S. military, Public Health Services, and Department of Veterans Affairs healthcare facilities.
CRNAs/nurse anesthesiologists represent more than 80% of the anesthesia providers in rural counties. Many rural hospitals are critical access hospitals, which often rely on independently practicing CRNAs/nurse anesthesiologists for anesthesia care. Half of U.S. rural hospitals use a CRNA-only model for obstetric care, and they safely deliver pain management care, particularly where there are no physician providers available, saving patients long drives of 75 miles or more.
Numerous peer-reviewed studies have shown that CRNAs are safe, high quality and cost-effective anesthesia professionals who should practice to the full extent of their education and abilities. According to a 2010 study published in the journal Nursing Economic$, CRNAs acting as the sole anesthesia provider are the most cost-effective model for anesthesia delivery, and there is no measurable difference in the quality of care between CRNAs and other anesthesia providers or working within another anesthesia delivery model. Researchers studying anesthesia safety found no differences in care between nurse anesthetists and physician anesthesiologists based on an exhaustive analysis of research published in the United States and around the world, according to a scientific literature review prepared by the Cochrane Collaboration, the internationally recognized authority on evidence-based practice in healthcare. A study published in Medical Care (June 2016) found no measurable impact in anesthesia complications among states with and without nurse anesthetist scope of practice or practice restrictions.
CRNAs/nurse anesthesiologists provide anesthesia in collaboration with surgeons, dentists, podiatrists, physician anesthesiologists, and other qualified healthcare professionals.
When anesthesia is administered by a nurse anesthetist, it is recognized as the practice of nursing; when administered by a physician anesthesiologist, it is recognized as the practice of medicine. Regardless of whether their educational background is in nursing or medicine, all anesthesia professionals give anesthesia the same way.
As advanced practice registered nurses, CRNAs/nurse anesthesiologists practice with a high degree of autonomy and professional respect. CRNAs/nurse anesthesiologists are qualified to make independent judgments regarding all aspects of anesthesia care based on their education, licensure, and certification. They are the only anesthesia professionals with critical care experience prior to beginning formal anesthesia education.
The all-CRNA model, where anesthesia delivery is staffed and directed by CRNAs avoids duplication of services, promotes efficient utilization of anesthesia providers, and reduces cost. As interests compete for limited resources in healthcare, groups and facilities seeking to minimize the cost of anesthesia services can achieve excellent cost savings as compared to other anesthesia practice models by the implementation of an all–CRNA model.
Legislation passed by Congress in 1986 made nurse anesthetists the first nursing specialty to be accorded direct reimbursement rights under the Medicare program and CRNAs/nurse anesthesiologists have billed Medicare directly for 100% of the physician fee schedule amount for services. In 2020, U. S. Congress passed legislation that included a nondiscrimination provision to prohibit health plans from discriminating against qualified licensed healthcare professionals, such as CRNAs/nurse anesthesiologists and other non-physician providers, solely based on their licensure.
In 2001, CMS changed the federal physician supervision rule for nurse anesthetists to allow state governors to opt out of this facility reimbursement requirement (which applies to hospitals and ambulatory surgical centers) by meeting three criteria:
To date, 25 states and Guam have opted out of the federal physician supervision requirement. Additional states do not have supervision requirements in state law and are eligible to opt out should the governors elect to do so.
On a nationwide basis, the average 2023 malpractice liability insurance premium for self-employed CRNAs/nurse anesthesiologists was 25 percent less than it was in 1996. When adjusted for inflation through 2020, the reduction in premiums was even greater, at 71 percent.
AANA membership is open to CRNAs/nurse anesthesiologists — both practicing and retired — as well as current and aspiring nurse anesthesia residents. More than 65,000 of the nation’s CRNAs/nurse anesthesiologists and residents are members of AANA. That’s 88 percent of all U.S. nurse anesthetists/nurse anesthesiologists.
