Validation of new trauma triage rules for trauma attending response to the emergency department.

INTRODUCTION The American College of Surgeons Committee on Trauma has suggested triage criteria for the immediate attendance of a trauma surgeon to an injured patient in the emergency department. This study validates the accuracy of these criteria in identifying high-risk trauma patients and assesses the impact of trauma surgeon response time. METHODS A study group of trauma patients with a systolic blood pressure (SBP) < 90 mm Hg, Glasgow Coma Scale (GCS) score < 8, airway compromise managed with endotracheal intubation (ETI) or surgical airway, or gunshot wound (GSW) to the neck or torso were compared with a control group of patients meeting none of these criteria. Outcome measurements included Injury Severity Score (ISS), duration of hospitalization (length of stay [LOS]), intensive care unit (ICU) days, direct transfer to the ICU or operating room, and mortality. For the study group, trauma surgeon response times, < or = 15 minutes and > 15 minutes, were compared for age, ISS, LOS, ICU days, mortality, and direct transfer to the ICU or operating room. Statistical analysis was performed using the t test and the Yates-corrected chi(2) test (p < 0.05), with odds ratios calculated on the basis of trauma activation criteria and outcome measures. Multiple logistic regression was used to assess the relation between the independent variables SBP, GCS, ETI, and GSW with direct transfer to the ICU or operating room and mortality. RESULTS A total of 4,910 patients were identified, including 791 study group patients. The mean ISS, LOS, ICU days, and mortality were significantly higher in the study group (p < 0.01). Odds ratios of the study group for direct transfer to the ICU or operating room were 91 and 2 for ETI, 23 and 1.4 for GCS score < 8, 8 and 2.2 for GSW, and 7 and 1.6 for SBP < 90 mm Hg, respectively. The odds ratios for mortality were 39 for ETI, 104 for GCS score < 8, 12 for GSW, and 74 for SBP < 90 mm Hg. Regression analysis demonstrated that GSW, SBP < 90 mm Hg, and ETI predicted ICU admission; GSW, SBP < 90 mm Hg, and ETI predicted operative intervention; and GCS score < 8, SBP < 90 mm Hg, and ETI were associated with mortality. Trauma surgeon response times were available for 658 (83%) of the study group patients. No significant differences were found between the two response groups. CONCLUSION Trauma patients meeting the triage criteria proposed by the American College of Surgeons Committee on Trauma have more severe injuries, a higher mortality rate, and longer hospital and ICU stays than control patients. SBP < 90 mm Hg, ETI, and GSW are predictive of urgent operating room use and ICU admission. A significantly higher mortality rate is associated with SBP < 90 mm Hg, ETI, and GCS score < 8. Incorporating these criteria into trauma center triage rules to identify high-risk injured patients is warranted. However, trauma surgeon response time < or = 15 minutes was not associated with improved patient outcome, and optimal response time remains uncertain.

Cirrhosis in the trauma victim --- effect on mortality-rates

To evaluate the impact cirrhosis has on survival the records of 40 cirrhotic trauma victims from the registries of two Level 1 trauma centers were reviewed and probability of survival calculated using the TRISS methodology. Mechanism of injury, anatomic location, involvement of single or multiple sites, presence of ascites, elevations in serum glutamic oxaloacetic transaminase (SGOT), alkaline phosphatase, serum bilirubin, prothrombin time (PT), and hypoalbuminemia were tabulated for each patient. Contingency tables were created for injury and hepatic parameters, as related to survival, and subjected to chi square analysis. Loglinear analysis was performed on all significant parameters to evaluate the independent effects of injury characteristics and hepatic insufficiency on survival. Predicted survival was 93%; observed survival was 70% (Z = -6.92; p less than 0.001). Cause of death was multiple-system organ failure (9) and closed head injury (3). Admission markers of poor outcome included one or more of the following: ascites, elevated PT or bilirubin, history of motor vehicle accident, multiple trauma, or blunt abdominal trauma requiring laparotomy. Loglinear analysis revealed that the presence of ascites, elevated PT, or bilirubin, further diminished the rate of survival for any individual injury characteristic. We concluded that survival among cirrhotic trauma victims was significantly lower than predicted. In addition the presence of hepatic insufficiency further diminishes survival, regardless of the injury sustained.

Asymptomatic occult cervical spine fracture : case report and review of the literature

Lack of case documentation has led to controversy over the existence of asymptomatic occult cervical spine injury. We report a case of an elderly patient involved in a motor vehicle accident who sustained an asymptomatic occult cervical spine injury, and review the literature with regard to this controversial injury.

The development of a validated checklist for thoracentesis: preliminary results.

Thoracentesis is an invasive procedure known to result in complications. Procedure skills should be taught and evaluated more effectively to improve health care quality. Validated checklists are central to teaching and assessing procedural skills. The results of the first step of the validation of a thoracentesis checklist are described. A comprehensive literature review of articles published on thoracentesis did not yield a validated checklist. A modified Delphi technique, involving a panel of 8 interdisciplinary, interinstitutional experts, was used to develop a thoracentesis checklist. The internal consistency coefficient using Cronbach’s α was .94. Developing the 23-item thoracentesis checklist for teaching and assessing thoracentesis is the first step in the validation process. For this checklist to become further validated, it should be implemented and studied in the simulation and clinical environments.
