Clinical Trial Controlled Clinical Trial
Effect of the Advanced Trauma Life Support program on medical students' performance in simulated trauma patient management.
Part of the senior medical students' examination at the University of Toronto involves testing with simulated patient management. We compared the performance in these simulations of senior medical students who received Advanced Trauma Life Support (ATLS) training with those who did not receive ATLS training. ⋯ The ATLS course, both complete and audit status, prepares students more appropriately for managing trauma patients as judged by trauma simulation scenarios. Consideration should be given for including ATLS as an integral part of the senior medical student curriculum.

The Injury Severity Score (ISS) does not take into account multiple injuries in the same body region, whereas a New ISS (NISS) may provide a more accurate measure of trauma severity by considering the patient's three greatest injuries regardless of body region. The purpose of this study was to evaluate the ISS and NISS in patients with blunt trauma. ⋯ The NISS often increases the apparent severity of injury and provides a more accurate prediction of short-term mortality. The benefit associated with using the NISS rather than the ISS must be weighed against the disadvantages of changing a scoring system and the potential for still greater improvements.

Abdominal computed tomographic (CT) scans are used in the evaluation of blunt trauma. The purpose of this study was to determine if isolated intraperitoneal fluid seen on CT scan necessitates laparotomy. ⋯ Exploratory laparotomy was therapeutic in 94% of patients. Isolated intraperitoneal fluid on CT scan after blunt trauma mandates laparotomy.

Comparative Study
Preferential benefit of implementation of a statewide trauma system in one of two adjacent states.
Implementation of Oregon's trauma system was associated with a reduction in the risk of death for hospitalized injured patients. An alternative explanation for improved outcome, however, is favorable concurrent temporal trends, e.g., new technologies and treatments. ⋯ Assuming that the two states demonstrated similar concurrent temporal trends, the findings support the conclusion that improved outcomes among injured patients in Oregon may be attributed to the institution of a statewide trauma system.

Recent attention concerning the adverse outcomes of blood transfusion has resulted in decreased blood product usage for nonemergency care. We hypothesized that there has also been a decrease in blood product use in the management of seriously injured adults. ⋯ Between 1991 and 1995 there have been significant reductions in both the number of trauma patients receiving blood products and the total number of units transfused. These findings may reflect lower or abandoned hemoglobin transfusion triggers and increased awareness of complications related to transfusion.
