AbstractIt is widely assumed that infections are the principal cause and primary outcome determinant of the syndrome of Multiple Organ Failure (MOF) in critically ill patients. Infections are frequent in these patients, but the prevention and treatment of infections may not influence the course of MOF. This study tested the hypothesis that infections play a decisive role in the outcome of MOF. Data were gathered concurrently on all adult patients admitted over an 18-month period to a non-cardiac surgical ICU at a university hospital and recorded in a computer database. Sepsis was defined as a state characterized by at least three of the following: fever, tachycardia, leukocytosis or leukopenia, increased cardiac index, reduced systemic vascular resistance, and hypercatabolism manifested by nitrogen-wasting. The presence of an infection was not required for the diagnosis of sepsis. Mild sepsis was defined as the presence of three or four parameters. Severe sepsis was defined as the presence of five or six parameters. MOF was defined as the development of dysfunction of at least two of the following major organ systems: cardiac, gut, pulmonary, renal, cerebral, and hepatic. Of 749 admissions, 73 patients developed MOF. Thirty four (47%) had a documented source of infection, 37 (51%) had positive blood cultures, and all had sepsis. Hospital mortality was 66 percent (48 of 73 patients). Death could not be predicted by bacteremia (P > 0.25), nor by the presence of an infectious source (P = 1.0), but was strongly associated with severe sepsis (P < 0.0005).(ABSTRACT TRUNCATED AT 250 WORDS)
