Trauma care reimbursement in rural hospitals: implications for triage and trauma system design.
American College of Surgeons triage guidelines recommend rapid identification and transfer of seriously injured patients to regional trauma centers, bypassing local hospitals if necessary. This approach raises concerns about the potential negative financial impact of implementing such triage strategies on already strained rural hospitals. ⋯ The study demonstrates that as injury severity increases, costs and charges increase, but reimbursement does not keep pace with these increased charges. The rural hospital was projected to lose an average of $25,000 for each patient with an Injury Severity Score over 15. This study supports the rapid triage and transport of the seriously injured patient from the rural hospital to the regional trauma center both for improved patient outcome and for the hospital's best interest. The potential impact of such a system on the trauma center also needs to be addressed.

Emergent abdominal sonography as a screening test in a new diagnostic algorithm for blunt trauma.
Although there is an interest in emergent abdominal sonography (EAS), the clinical utilization of EAS in North America is minimal. The purpose of this study was to develop a new diagnostic algorithm for blunt abdominal injury based on a prospective blinded comparison of EAS, diagnostic peritoneal lavage (DPL), and computed tomography (CT). EAS (+ = fluid, - = no fluid) was performed before the DPL or CT, in 400 patients with a mean Injury Severity Score of 26; 293 had a CT and 107 had a DPL. ⋯ Based on these results, a diagnostic algorithm was developed using EAS as a screening test with selective use of DPL and CT. Emergent abdominal sonography performed by clinician sonographers is a rapid and accurate test for peritoneal fluid in blunt trauma victims, and the need for laparotomy in patients with a negative EAS is rare. Our study supports the routine use of EAS as a screening test in a diagnostic algorithm for the evaluation of blunt abdominal trauma.

There are few large series of the long-term results of severe devascularized, open fractures to the lower extremity. Therefore, we retrospectively reviewed our experience with 35 consecutively admitted patients who sustained Gustilo Type IIIC injuries and who presented to our Reimplantation Center between 1984 and 1987. To our knowledge, this group of patients represents the largest series of this injury reported to date. ⋯ Subsequent management included liberal use of microsurgical free transplantation to overcome soft tissue defects; bone grafting as soon as infection and soft tissue coverage permitted and delayed wound closure. Our approach differs in that definitive wound closure is avoided for 4 to 6 weeks to allow resolution of myonecrosis secondary to initial ischemia and subsequent reperfusion injury. Contraindications to this aggressive revascularization approach are poor patient health before injury, completely severed limb, segmental tibial loss greater than 8 cm, ischemia time greater than 6 hours, and severance of the posterior tibial nerve.

Improved accuracy of burn wound assessment using laser Doppler.
The utility of the laser Doppler for determining burn depth has been questioned because of problems with technology and methodology. This study prospectively evaluates the ability of a new laser Doppler technique to predict burn healing time. Using the Periflux System 4000 laser Doppler, readings were taken on 305 burns (147 patients) on postburn day 3 or 4. ⋯ AHWA, F100, and RFC were included in the final discriminant function explaining 72% of the healing time variance (Wilks' lambda value 0.28; p value <0.0001). Predicted outcome = 0.05(AHWA) + 0.31(F100) + 5.0(RFC) - 2.3. With this derived function, there is 94% accuracy in the prediction of burn wound healing time compared with a physician predictive accuracy of 70%.

Comparative Study
Predicting the need to pack early for severe intra-abdominal hemorrhage.
To determine if the decision to pack for hemorrhage could be refined. ⋯ Patients who suffer severe injury, hypothermia, refractory hypotension, coagulopathy, and acidosis need early packing if they are to survive. Failure to control hemorrhage is related to severity of injury and delay in the use of pack tamponade. A specific protocol that mandates packing when parameters reach a critical limit should be considered.
