Prognostic Indices for Assessment of Patients with Gram-Negative Bacteremia and Shock. An Evaluation of Hemodynamic, Respiratory and Metabolic Parameters
Quantitative assessment of the severity of illness and prognosis of critically ill patients provides a basis for objective evaluation of selective aspects of patient care. In studies on patients with acute myocardial infarction and shock, linear combinations of cardiac index and lactate were most reliable for estimating severity of illness and prognosis (1). When patients with shock due to drug overdose were analyzed, two different variables emerged as the most reliable indicators, systolic pressure and arterial pH (2). The present study was undertaken to identify the most useful hemodynamic, respiratory and metabolic variables for assessing the severity of illness in patients with shock due to gram-negative bacterial infection. Prognostic indices based on combinations of these variables were derived. The effect of the time of the measurements also was evaluated to determine its influence on the reliability of the prognosis.
