There have been several attempts to develop a scoring system that can accurately reflect the severity of a trauma patient's injuries, particularly with respect to the effect of the injury on survival. Current methodologies require unreliable physiologic data for the assignment of a survival probability and fail to account for the potential synergism of different injury combinations. The purpose of this study was to develop a scoring system to better estimate probability of mortality on the basis of information that is readily available from the hospital discharge sheet and does not rely on physiologic data. ⋯ The HARM score is an effective tool for predicting probability of in-hospital mortality for trauma patients. It outperforms both the TRISS and ICD9-CM Injury Severity Score (ICISS) methodologies with respect to both discrimination and calibration, using information that is readily available from hospital discharge coding, and without requiring emergency department physiologic data.

The purpose of this study was to quantify the relationship between negative base excess (base deficit) and lactate as correlates of oxygen debt and the probability of the early acute respiratory distress syndrome (ARDS) response and with regard to the mediator and metabolic response characteristic of this disease. ⋯ These data suggest that the maximum posttrauma oxygen debt (quantified by the ischemia correlates of negative base excess and lactate) is a critical primary determinant of the later fulminant autoinflammatory EARLY ARDS response mediated by the host's endogenous cytokine mediators.
