Summary
Trauma team activation (TTA) protocols need re-evaluation due to high overtriage rates. Physiological and anatomical criteria improve accuracy compared to mechanism of injury, reducing unnecessary activations.
Area of Science:
- Emergency Medicine
- Trauma Surgery
- Clinical Protocol Optimization
Background:
- Trauma team activation (TTA) protocols vary, raising concerns about overtriage.
- Evaluating the performance of existing TTA protocols is crucial for patient care efficiency.
Purpose of the Study:
- To investigate the performance of a specific trauma team activation protocol.
- To assess the sensitivity, positive predictive value (PPV), and overtriage rates of different TTA criteria.
Main Methods:
- Retrospective analysis of 809 injured patients from January 2004 to December 2005.
- Evaluation of TTA criteria including mechanism of injury, physiological/anatomical factors, and interfacility transfer.
- Analysis focused on sensitivity, PPV, and overtriage (1 - PPV).
Main Results:
- The overall protocol showed 87% sensitivity, 22% PPV, and 78% overtriage.
- Mechanism of injury criteria resulted in 14% sensitivity, 7% PPV, and 93% overtriage.
- Physiological/anatomical criteria and interfacility transfer demonstrated higher PPV and less overtriage. Undertriage affected 13% of patients.
Conclusions:
- TTA protocols based on physiological, anatomical, and interfacility transfer criteria offer higher precision than those relying solely on mechanism of injury.
- The current TTA protocol requires re-evaluation due to significant overtriage observed in the study.
- Optimizing TTA criteria is essential to balance sensitivity and reduce unnecessary resource utilization.

01:29Increased Intracranial Pressure ll: Pathophysiology
Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
01:14Increased Intracranial Pressure l: Introduction
Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
01:28Traumatic Brain Injury l: Introduction
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:27Post-traumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events, are a...

01:24Drug Toxicity: Risk factors
Adverse Drug Reactions (ADRs) are potential complications that arise during pharmacotherapy, influenced by multiple risk factors. Age plays a significant role; both neonates and the elderly are at heightened risk due to their respective immature and diminished metabolic and elimination processes. Gender also impacts ADRs, with females experiencing a 1.5 to 1.7-fold greater risk than males, which may be linked to pharmacokinetic, pharmacodynamic, and hormonal differences. Notably, neonates, the...
