New surgical scoring system to predict postoperative mortality.

Purpose: There is still no easy and highly useful method to comprehensively assess both preoperative and intraoperative patient statuses to predict postoperative outcomes. We attempted to develop a new scoring system that would enable a comprehensive assessment of preoperative and intraoperative patient statuses instantly at the end of anesthesia, predicting postoperative mortality.

Methods: The study included 32,555 patients who underwent surgery under general or regional anesthesia from 2008 to 2012.
