This prospective observational study aims to evaluate the effectiveness of chest trauma scoring systems in predicting morbidity and mortality in patients with blunt chest trauma in Iraq. The primary questions it seeks to address are:

How accurately do chest trauma scoring systems predict mortality and critical outcomes such as ICU admission or the need for advanced interventions? How well do these scoring systems stratify patients based on injury severity in a resource-limited setting? Are there any demographic or clinical factors that impact the predictive performance of these scoring systems?

Participants will:

Be assessed using chest trauma scoring systems upon arrival at the emergency department to determine risk levels.

Have demographic and clinical data, including age, gender, injury mechanism, comorbidities, and length of hospital stay, collected to explore potential associations with outcomes.

Chest trauma is a major cause of morbidity and mortality, often resulting from motor vehicle accidents, falls, or physical assaults. It can lead to serious complications such as pulmonary contusions, rib fractures, and damage to thoracic organs. The Chest Trauma Score (CTS) helps assess injury severity by considering factors like age, number of rib fractures, and pulmonary contusion severity. Higher CTS values are associated with worse outcomes, such as prolonged mechanical ventilation and higher mortality rates. Early identification using this scoring system improves clinical decision-making and outcomes.

Despite the global utility of trauma scoring systems, there is limited research on their application in developing countries like Iraq, where trauma care is often constrained by limited resources and inconsistent protocols. In Iraq, blunt chest trauma is a prevalent issue due to frequent road traffic accidents and other causes. However, a lack of locally validated tools such as CTS hinders the ability of healthcare providers to assess injury severity accurately and predict outcomes.

This study aims to evaluate the effectiveness of the Chest Trauma Score in predicting morbidity and mortality among patients with blunt chest trauma in Iraq. By addressing this research gap, the findings will contribute to improving trauma care protocols, informing policy decisions, and enhancing the overall healthcare system's capacity to manage chest trauma effectively.

Inclusion Criteria:

• Patients diagnosed with blunt chest trauma.
• Patients presenting to the emergency department within 4 hours.
• Patients (or their legal representatives) must provide informed consent to participate in the study.
• Patients who can be assessed using the Chest Trauma Score at the time of arrival (e.g., having stable enough vitals to allow for evaluation).

Exclusion Criteria:

• Patients with penetrating chest trauma (e.g., gunshot or stab wounds), as the Chest Trauma Score is typically used for blunt trauma.
• Patients presenting with chest conditions unrelated to trauma (e.g., pneumonia, COPD exacerbation, or other non-traumatic causes of chest pain or respiratory distress).
• Patients with severe pre-existing comorbidities (e.g., end-stage heart failure, terminal cancer) where trauma is unlikely to be the primary cause of morbidity or mortality.
• Patients with missing or incomplete clinical data, including imaging or vital signs necessary to calculate the CTS accurately.
• Patients who refuse consent or do not agree to the use of their data for research purposes.

The study population will consist of adult patients aged 18 years and older presenting to the emergency department with blunt chest trauma. Participants will be assessed using the Chest Trauma Score (CTS) to predict morbidity and mortality, and data on demographics, injury mechanisms, and clinical outcomes will be collected. The study aims to include a diverse sample from varying age groups and both genders to evaluate the score's performance across different subgroups.
