Multicenter Study
Low-impact falls: demands on a system of trauma management, prediction of outcome, and influence of comorbidities.
Falls from a low height are an extremely common source of injury, the severity of which is often underestimated. As a result, low fall patients are usually not transferred to Level I trauma centers. There are surprisingly few systematic data relating to the demands made on systems of trauma care by patients with low falls. This study addresses this issue using information from a comprehensive national trauma database. The performance of TRISS methodology, and the factors associated with prolonged hospital stay, in low fall patients is also examined. ⋯ Patients with low falls make considerable demands on a system of trauma care. TRISS methodology performs less well in this group than with other types of injury. Chronic medical conditions are associated with increased mortality and more prolonged stay after a low fall. Between-institutional variation in length of stay was considerable and this, along with the poor performance of predictive models derived from routinely collected clinical data, make it unlikely that length of stay could be used as a measure of institutional performance. More robust audit measures for patients with low falls are required.

Comparative Study Clinical Trial
Prospective comparison of admission computed tomographic scan and plain films of the upper cervical spine in trauma patients with altered mental status.
The accurate evaluation of patients with multiple injuries is logistically complex and time sensitive, and must be cost-effective. We hypothesize that computed tomographic (CT) scan of the upper cervical spine (occiput to C3 [Co-C3]) would add little to the initial evaluation of patients with multiple injuries who have altered mental status. ⋯ CT scan of Co-C3 was superior to plain films in the early identification of upper cervical spine injury. Plain films failed to identify 45% of upper cervical spine injuries; four of these missed injuries resulted in motor deficits. Our study supports the practice guidelines developed by the Eastern Association for the Surgery of Trauma for clearance of the upper cervical spine in patients with altered mental status, as all patients with injuries were identified using these guidelines.

Emergency department thoracotomy (EDT) is a dramatic but rarely lifesaving intervention. Clinical variability regarding indications for EDT has yet to be quantified. Members of the Eastern and American Associations for the Surgery of Trauma were questioned by mail to evaluate which clinical and demographic factors influence the decision to perform EDT and whether physicians perform EDT in accordance with current practice guidelines. ⋯ A lack of agreement exists regarding the indications for EDT in multiple clinical scenarios as well as in defining SOL. Indications for EDT were liberal, especially for blunt trauma-related indications, and were determined by clinical parameters, not by physician or institutional factors. Our results suggest that clinical practice is at variance with Advanced Trauma Life Support guidelines. We recommend that practice guidelines for EDT be established on the basis of a consensus definition of SOL to allow for a more uniform and selective approach to EDT.

Elderly trauma patients have been shown to have a worse prognosis than young patients. Age alone is not a criterion for trauma team activation (TTA). In the present study, we evaluated the role of age > or = 70 years as a criterion for TTA. ⋯ Elderly trauma patients have a high mortality, even with fairly minor or moderately severe injuries. A significant number of elderly patients with severe injuries do not meet the standard criteria for TTA. It is suggested that age > or = 70 years alone should be a criterion for TTA.

The differentiation of duodenal perforation from duodenal hematoma is not always possible with computed tomography (CT). Our diagnostic guideline has included duodenography to investigate CT findings of periduodenal fluid or wall thickening. However, the utility of duodenography as a diagnostic study in blunt abdominal trauma is not defined. We evaluated duodenography as a diagnostic test in patients with suspected blunt duodenal injuries (BDIs). ⋯ Duodenography has a low sensitivity in patients with suspected BDI by CT findings and is of minimal utility in diagnostic evaluation. Retroperitoneal extraluminal air seen on CT is an important sign of BDI requiring surgical repair.
