Predicting older adults who return to the hospital or die within 30 days of emergency department care using the ISAR tool: subjective versus objective risk factors

摘要

Background We sought to evaluate the ability of the Identification of Seniors At Risk (ISAR) tool to differentiate between older adult patients having a poor outcome within 30 days of emergency department (ED) care and those who do not. We compare prognostic accuracy of subjective versus objective risk factors.
