Why? Because of a inflexible staffing structure due to the fact AA’s can not work independently, they must work as a team under direct supervision. This structure drives up cost and produces a high risk of billing fraud. Anytime there is medicare fraud, the patient ultimately suffers because of the decreased access to care.
In comparison, CRNA’s offer the best health care value since they are autonomous within the patient care team whereas AA’s are dependent and can only take orders from a physician.
