Introduction
Clinicians often encounter abnormal vital signs at the time of hospital discharge.  However the risk  of  adverse post-discharge outcomes associated with an abnormal blood pressure at time of hospital discharge reading is unknown. In this study we quantify the risk of post-discharge outcomes throughout the entire range  of systolic blood pressure(SBP).  We hypothesize that the lowest risk would occur in readings that are normotensive and an increased risk would be observed at high or low SBP values.
