Evaluation of estimation of physiologic ability and surgical stress (E-PASS) to predict the postoperative risk for hip fracture in elder patients

Abstract

These results suggest that E-PASS may be useful for predicting postoperative risk and estimating medical expense for surgical cases with hip fracture.

New Equations for Predicting Postoperative Risk in Patients with Hip Fracture

“…They reported an excellent correlation between predicted and observed mortality in patients treated by elective gastrointestinal surgery. We reported the PRS and CRS were well correlated with surgical outcomes in patients with hip fractures and they were effective and reproducible for prediction of the postoperative course at surgical hospitals in earlier [8,9] and current studies. Because the PRS facilitates prediction of the postoperative course before patients are subjected to surgery, we suggest it is the preferable method for obtaining equations for morbidity and mortality prediction in patients considered for hip fracture surgery.…”

“…When E-PASS was applied to gastrointestinal and pulmonary surgery, the comprehensive risk score (CRS) correlated with mortality and morbidity rates [6,17,31]. We reported the postoperative hospital morbidity and mortality rates increased linearly with the preoperative risk score (PRS) and CRS and they correlated in patients who had undergone osteosynthesis or arthroplasty for hip fracture [8,9]. Furthermore, equations for predicting 30-day and inhospital mortality rates using the CRS correlated well with observed mortality rates in patients undergoing elective gastrointestinal surgery [7].…”

“…In several studies, the Estimation of Physiologic Ability and Surgical Stress (E-PASS) scoring system correlated with the incidence of postoperative morbidity and mortality and the severity of potential postoperative complications [8,9]. It also correlated with the length and cost of hospitalization [9].…”
