    AbstractThe purpose of this systematic review was to evaluate the predictive validity of the Identification of Seniors at Risk (ISAR) Tool in identifying elderly patients at risk of adverse outcomes after a visit to the emergency department (ED). Since older adults are frequently sent to the ED, screening for risk of adverse outcomes in elderly patients is increasingly important in the ED. Also it is a way to ensure that interventions based on a comprehensive geriatric assessment (CGA) are provided to patients identified at risk to reduce the risk of adverse outcomes. The ISAR is a six-item risk-screening tool for elderly patients seen in the ED. However the predictive validity of ISAR is controversial. Relevant studies from January 1999 through December 2014 were searched systematically in PubMed, Cochrane Library, Web of Knowledge, Scopus, CINAHL, Elsevier ScienceDirect databases. The language was restricted to English. This review was based on the recommendations of the Cochrane Handbook of Diagnostic Test Accuracy Reviews. Ten studies (8680 patients) were included in this review. With a cutoff score at least 2, the ISAR was proved to have poor validity related to revisiting the ED (AUC: 0.59-0.60) and hospital readmission (AUC: 0.59-0.60). The predictive validity of the ISAR related to mortality and composite outcomes was graded as poor to fair. It is not suitable to use the ISAR alone for identifying seniors at risk for adverse outcomes in the ED.
