![]() The ASA score is assigned based on the presence and severity of systemic disease in a patient. Research has shown that the implementation of the classification system correctly predicts the frequency and severity of adverse events, which improves patient outcomes. The ASA Physical Status Classification System has been shown to predict the frequency of perioperative morbidity and mortality. Using the ASA Physical Status Classification System to evaluate and prepare for possible adverse events remains one of the most widely used pre-operative screening methods for all providers worldwide. In 2014, the ASA provided access to a catalog of examples for simplification when assigning an ASA score, increasing accuracy and decreasing inter-observer variation. Studies have shown that adding examples for each respective score aided both anesthesia and non-anesthesia providers consistently classifying patients accurately. This situation proves to be a problem that is more prevalent outside the specific specialty, posing a potential threat to the success of healthcare teams composed of multiple providers from multiple specialties. Assessment and evaluation of patients can vary between providers in different specialties compared to the staff anesthesiologists, causing a significant increase in standard deviation even when participants had access to the same medical records. Issues of ConcernĪ topic of concern commonly encountered with assigning ASA scores is that there is often significant variation with how providers may classify the same patient. ![]() Despite its setbacks, it has since become a standard practice during perioperative encounters and plays a key role in preventative medicine associated with anesthesia. The goal of creating the ASA Physical Status Classification System (ASA-PS) was to improve patient outcomes and predict perioperative risk. Patients assigned to higher numerical categories have increased risk of perioperative adverse events. Assigning this score, ranked ASA I through ASA VI, would thereby attempt to categorize the patient's risk of perioperative complications based on their physical status and overall health. Pre-operatively, the patient is subjectively assigned a score according to their physical status, which is determined by the anesthesiologist after considering patient presentation, history, and functional limitations. ![]() In 1963, the American Society of Anesthesiologists instituted a system to assess a patient's physical health status and clinical risk during anesthetic administration and surgical operation. ![]()
