A study performed at Tokyo Women’s Medical University attempted to develop a new scoring system that would enable a comprehensive assessment of preoperative and intraoperative patient statuses instantly following entry of data into an electronic anaesthesia chart, accurately and automatically predicting postoperative mortality. The usefulness of this new scoring system, the SASA, was compared with that of the surgical Apgar score (sAs) and American Society of Anesthesiologists physical status classification (ASA-PS), which are the components of the new system. The study, which included 32,555 patients who underwent surgery under general or regional anaesthesia from 2008 to 2012, used MetaVision to extract factors presumably associated with surgical outcomes, such as patient characteristics and ASA-PS, and the three intraoperative indexes used to calculate the sAs. The authors found that while the sAs and ASA-PS were shown to be extremely useful for predicting mortality within 30 days of surgery, an even higher predictive ability was demonstrated by the SASA, which combines these scoring systems, and conclude, “We expect that the SASA will be widely used as a new easy scoring system for predicting prognosis, allowing a comprehensive assessment of perioperative patient status and automatic calculation of scores at the end of entering data into electronic anesthesia charts.”
