The Rapid Response Team (RRT) represents an important advance in the management of deteriorating ward patients and is recommended as a patient safety measure. Most studies on RRT evaluate the effects of its implementation on rate reduction of cardiopulmonary arrest outside the ICU and hospital mortality, with limited information on the criteria for RRT calls and predictive factors associated with hospital mortality [1],[2]. Therefore, our objective was to determine what factors are associated with hospital mortality for patients seen by the RRT at the Hospital Israelita Albert Einstein (HIAE).
