Predictive Value of Chest Trauma Score , Revised Trauma Score , and Glasgow Coma Scale in Patients Presenting With Chest Trauma at Assiut University Emergency Unit.

Thoracic trauma is a critical clinical entity and a major global public health burden, representing the second most frequently occurring unintentional traumatic injury and the third most common cause of death-following head and abdominal injuries-in patients with polytrauma. It places a substantial demand on emergency departments and directly accounts for 20% to 25% of all trauma-related fatalities worldwide(1). The severity of these injuries is underscored by persistently high mortality rates, which can reach up to 60% in cases of severe blunt chest trauma depending on the healthcare setting. Recent epidemiological data indicates that among potentially preventable trauma deaths, thoracic injuries represent up to 41%, with blunt mechanisms such as motor vehicle collisions acting as the primary driver (accounting for 80% to 92% of cases)(2). Given this significant risk profile, rapid and accurate clinical triage is vital. Current evidence consistently demonstrates that early recognition, protocolized multidisciplinary management, and the timely provision of definitive interventions at dedicated trauma centers are essential to decreasing morbidity and significantly reducing preventable trauma mortality(3).Effective initial assessment in the ED relies heavily on validated trauma scoring systems. GCS is the most universally utilized tool for evaluating a patient's level of consciousness, calculating a score between 3 and 15 based on three physiological parameters: eye opening, verbal response, and motor response. RTS is a broader physiological scoring system combining the GCS, systolic blood pressure, and respiratory rate. CTS is a specific, targeted assessment tool designed to quantify the severity of thoracic injuries.

Inclusion Criteria:

• Age threshold: Patients aged 18 years and older (pediatric physiology requires entirely different trauma scoring systems).
• Mechanism of injury: Patients presenting with acute blunt or penetrating thoracic trauma or both.
• Diagnostic confirmation: Patients with documented clinical or radiological evidence of chest injury (e.g., rib fractures, pulmonary contusion, pneumothorax, or hemothorax confirmed via X-ray, chest CT, or FAST).
• Time of presentation: Patients presenting directly to the emergency department within 24 hours of the trauma incident.

Exclusion Criteria:

• Inter-facility transfers: Exclude patients transferred from other hospitals. If they were already intubated, given sedatives, or resuscitated elsewhere, their admission scores will be artificially altered and will not reflect their true initial presentation.
• Dead on Arrival (DOA): Patients who arrive in cardiac arrest or expire before the initial primary survey and scoring can be completed.
• Isolated severe head trauma or massive burns: Patients whose clinical picture and need for intubation are overwhelmingly driven by severe traumatic brain injury (e.g., GCS < 8 from head injury alone without significant chest trauma) or massive burns, rather than the thoracic injury.
• Severe chronic cardiopulmonary disease: patients with known end-stage COPD, severe baseline heart failure, or those on home oxygen. Their baseline hypoxia or need for ventilation can confound the trauma scores' predictive value.
• Incomplete data: Patients whose medical records are missing the crucial variables needed to calculate the GCS, RTS, or CTS upon arrival.
