Hospitals that “lack a commitment to trauma care” have been associated with a higher incidence of unacceptable care and poor outcomes– Moylan JA, et al., J Trauma, 1976 – Detmer DE, et al., J Trauma, 1977

Comparison of Trauma SystemsComparison of Trauma SystemsWest JG, et al., Arch Surg, 1979Comparison of trauma patients who died
after arrival at a hospital– Orange Co., closest facility (n = 90) – San Francisco, single trauma center (n = 92)
“Preventable” deaths– Orange Co. 40 of 90 deaths (44%):
20/30 (66%) of non-CNS trauma 20/60 (33%) of CNS trauma pts
– SF: only one (about 1%)

Transfer of trauma patients to designated trauma centers has also been shown to improve outcomes:– West JG, et al., Arch Surg, 1983
Follow up to 1979 study Significant reduction in mortality by regionalization:
overall 20% preventable; TC 9% preventable– Shackford SR, et al., J Trauma, 1986– Waddell TK, et al., J Trauma, 1991

Effect of Trauma-Center Care on Effect of Trauma-Center Care on MortalityMortality
Trauma patients managed at 18 Level I trauma centers compared to 51 non-trauma centers (14 states)
Complete records available for:– 1104 patients who died – 4087 patients discharged alive
CDC funded
MacKenzie EJ, et al, NEJM, 2006

Effect of Trauma-Center Care on Effect of Trauma-Center Care on MortalityMortality
In-hospital mortality :– Trauma center: 7.6%; relative risk 0.80– Non-trauma center: 9.5%
One year mortality rate:– Trauma center 10.4%, relative risk 0.75– Non-trauma center: 13.8%
Differences in mortality rates primarily confined to patients with more severe injuries
![Page 27: Getting There: The Right Place at the Right Time Jeffrey P. Salomone, MD, FACS, NREMT-P Associate Professor of Surgery Emory University School of Medicine.](https://reader030.fdocuments.net/reader030/viewer/2022032706/56649de95503460f94ae4df7/html5/thumbnails/27.jpg)
You (or your patient) are 25% more likely to survive if taken to a trauma center.

Level I vs Level IILevel I vs Level II
Traditionally outcome between Level II and Level I centers viewed to be equivalent– Criteria for clinical care nearly identical– Level I primarily teaching / research facility

OvertriageOvertriage
Transporting minimally injured trauma patients to a trauma center
Overtriage rate of up to 50% considered acceptable
Often a financial / resource issue

Failure to transport major trauma patients to a trauma center
Undertriage rate of 5 – 10 % considered unavoidable, and is associated with an overtriage rate of 30 – 50%
Often a political issue

Physiologic derangement correlates well with severity of injury and can predict mortality– Baxt WB, et al., Ann Emerg Med, 1989
Patients with significant tachycardia and hypotension have typically lost 30 – 40% of their blood volume and often are in need of emergent transfusion and surgical intervention

Some patients with lethal injury may present with normal vital signs, especially if EMS response has been rapid– Reliance on only physiologic criteria may result in
undertriage

Several studies have documented noteworthy survival rates in patients with penetrating torso trauma transported to facilities with immediate surgical capabilities
Best survival rates are in patients with stab wounds to the chest that have vital signs upon arrival in the ED– Durham LA, et al., J Trauma, 1992– Velmahos GC, et al., Arch Surg, 1995– Rhee PM, et al., J Am Coll Surg, 2000

Mechanism of InjuryMechanism of Injury Falls
– Adults > 20 ft (one story is equal to 10 ft)– Children < 15 yrs: > 10 ft or 2-3 X height of the child
High-risk auto crash*– Intrusion, including roof: > 12” occupant site; > 18” any
site– Ejection (partial or complete) from automobile– Death in same passenger compartment– Vehicle telemetry data consistent with high risk of
injury Auto-pedestrian / auto-bicyclist thrown, run over, or with
significant (> 20 mph) impact Motorcycle crash >20 mph
* Removed: rollover, deformation to vehicle

MOI may aid in predicting serious injury– King AI, et al., J Trauma, 1995– Grande CM, et al., Crit Care Clin, 1990– Presswalla FB, Med Sci Law, 1978
MOI correlates least well with the presence of significant injury– Relying on these alone increases overtriage

Special Circumstances
Older adults: – risk of injury death increases after age 55– SBP < 110 may represent shock after age 55– Low impact mechanisms (e.g., ground level falls)
may result in severe injuries Children: should be triaged preferentially to
pediatric-capable trauma center Anticoagulation and bleeding disorders
