Prediction of survival chances for trauma patients is a basic requirement for evaluation of trauma care. The current methods are the Trauma and Injury Severity Score (TRISS) and A Severity Characterization of Trauma (ASCOT). Scales for scoring injury severity are part of these methods. This study compared three injury scales, the Injury Severity Score (ISS), the New ISS (NISS), and the Anatomic Profile (AP), in three otherwise identical predictive models. ⋯ The AP and NISS scores particularly both managed to outperform the ISS score in correctly predicting survival chances among a Dutch trauma population. Trauma registries stratifying injuries by the ISS score should evaluate the use of the NISS and AP scores.

Management strategies for blunt solid viscus injuries often include blood transfusion. However, transfusion has previously been identified as an independent predictor of mortality in unselected trauma admissions. We hypothesized that transfusion would adversely affect mortality and outcome in patients presenting with blunt hepatic and splenic injuries after controlling for injury severity and degree of shock. ⋯ Blood transfusion is a strong independent predictor of mortality and hospital length of stay in patients with blunt liver and spleen injuries after controlling for indices of shock and injury severity. Transfusion-associated mortality risk was highest in the subset of patients managed nonoperatively. Prospective examination of transfusion practices in treatment algorithms of blunt hepatic and splenic injuries is warranted.

This article describes the characteristics of missed lower urologic injuries at a level 1 trauma center using advanced trauma life support protocols. Between 1991 and 1996, 635 patients were treated for traumatic pelvic fractures. For the 43 patients with missed urologic diagnoses, the pelvic fracture pattern, initial evaluation, average delay to diagnosis and treatment, reason for the delay, and manner in which the lower urinary tract injury was discovered and treated were identified. ⋯ The findings show that 23% of all bladder and urethral disruptions associated with pelvic fractures were missed at initial evaluation. The pelvic fracture pattern, in addition to physical examination, should direct the urologic evaluation for trauma patients.
