de Gelder J, et al. - Researchers sought to determine the predictors of Emergency Department (ED) revisits and the link between ED revisits and 90-day functional decline or mortality. Although no useful clinical prediction model could be developed, the following factors were identified as independent predictors of a 30-day ED revisit: age, male sex, polypharmacy, and cognitive impairment. An early ED revisit was recognized as a strong new predictor of adverse outcomes in older adults.
