THE IMPACT OF AGE ON THE INNATE IMMUNE RESPONSE AND OUTCOMES AFTER SEVERE SEPSIS/SEPTIC SHOCK IN TRAUMA AND SURGICAL INTENSIVE CARE UNIT PATIENTS

Introduction Advancing age is a strong risk factor for adverse outcomes across multiple disease processes. However, septic surgical and trauma patients are unique in they incur two or more inflammatory insults. The effects of advanced age on sepsis pathophysiology and outcomes remain unclear. Methods We performed a single center, prospective observational cohort study of Surgical ICU patients with severe sepsis/septic shock.
