The relative impact of inhalation injury, burn size, and age on overall outcome following burn injury was examined in 1447 consecutive burn patients over a five and a half year period. The overall mortality for all patients was 9.5% (138 of 1447). The presence of inhalation injury, increasing burn size, and advancing age were all associated with an increased mortality (p < 0.01). ⋯ Using multivariate analysis inhalation injury was found to be an important variable in determining outcome, but the most important factor in predicting mortality was %TBSA burn (accuracy = 92.8%) or a combination of %TBSA burn and patient age (accuracy = 93.0%). Adding inhalation injury only slightly improved the ability to predict mortality (accuracy = 93.3%). The presence of inhalation injury is significantly associated with mortality after thermal injury but adds little to the prediction of mortality using %TBSA and age alone.

Comparative Study
A prospective comparison of two multiple organ dysfunction/failure scoring systems for prediction of mortality in critical surgical illness.
Multiple organ failure (MOF) is the primary cause of death in surgical intensive care units (SICU). Mortality increases with an increasing number of failed organs, but it has been recognized that lesser degrees of organ dysfunction occur commonly. Such gradations of the multiple organ dysfunction syndrome (MODS) are postulated to provide more descriptive and predictive power. ⋯ Death was equally likely for comparable degrees of organ dysfunction and failure. Mortality increased (p < 0.01, ANOVA) with higher scores in both systems. In patients with 9-12 organ dysfunction points, the number of failed organs was 1.5 +/- 0.2 in 34 survivors, versus 2.9 +/- 0.3 in the 14 nonsurvivors (p < 0.001).(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this study was to identify risk factors for thoracic/lumbar spine fractures in patients with blunt injuries and subsequently establish indications for obtaining surveillance thoracolumbar radiographs. Retrospective review of all patients with blunt injuries (n = 1485) admitted in 1992 to a level I trauma center with a discharge diagnosis of thoracolumbar spine fracture established entrance criteria for a 4-month prospective study. Relative risk of fracture (RR) was calculated. ⋯ Our data define these indications for obtaining thoracolumbar radiographs in patients with blunt injuries: back pain (RR1), fall > or = 10 feet, ejection from motorcycle/motor vehicle crash > or = 50 mph, GCS score < or = 8, (all RR2), and neurologic deficit (RR10). The sensitivity of our surveillance radiography protocol has increased to 100%. The absence of back pain does not exclude significant thoracolumbar trauma.

Quality assurance/quality improvement (QA-QI) is a priority for maintaining the highest standards of care in trauma systems. To be an effective tool for system review, the QA-QI indicators should identify patients with higher rates of morbidity and mortality from injury. While the American College of Surgeons (ACS) and the Joint Commission on Accreditation of Health Care Operations have identified certain audit filters within the trauma system, there are few data to substantiate the value of these audit filters for trauma care. ⋯ This study demonstrates that several ACS clinical indicators, as currently written, are not useful in identifying patients at higher risk for poor outcome. The indicators need further definition to be of value in the quality review process. Specifically, the study suggests that audit filters should be data driven and based upon analyses of large populations of injured patients and their outcomes to be valid QA-QI tools.

A possible way to circumvent the continuing decline in the number of autopsies is to perform computed tomography after death. The present study compares the pathologic findings of postmortem CT tomography (PMCT) in trauma fatalities with those disclosed upon conventional forensic autopsy. Within 6 hours of death, the bodies of 25 trauma victims underwent total body CT scanning, all with permission of the relatives, followed by conventional autopsy in 13 cases under court order. ⋯ In all, PMCT revealed 70.5% and autopsy 74.8% of the pathologic states. Although PMCT was not more effective than conventional autopsy in exposing pathologic entities, it increased the yield of findings when combined with conventional autopsy. Where conventional autopsy is unattainable, PMCT may be effective in shedding light on the pathologic state and mechanism of death in trauma fatalities.
