STUMBL vs TTSS in Predicting Morbidity and Mortality of Blunt Chest Trauma

NCT07270354 | Not Yet Recruiting

• 1 other identifier: STUMBL-TTSS-BluntChestTrauma
• Study Type: observational
• Target: 124
• Locations: 0 countries
• Sites: N/A

Brief Summary

This study aim to compare the effectiveness of the STUMBL Score and the Thoracic Trauma Severity Score (TTSS) in predicting morbidity and mortality in patients with blunt chest wall trauma, and to evaluate which scoring system provides greater clinical utility for early risk stratification and management decisions.

Conditions

Blunt Chest Wall Trauma

Keywords

Blunt; Chest wall trauma; Emergency department

Outcome Measures

Primary Outcomes (1)

• To compare the predictive accuracy of the STUMBL score and TTSS in forecasting morbidity and mortality in patients with blunt chest trauma

  14 day duration follow-up after ED admission

Secondary Outcomes (2)

• Easy of use of STUMBL score and TTSS score in emergency clinical settings

  14 day duration follow-up after ED admission

• To correlate each score with specific outcomes such as pneumonia, need for mechanical ventilation, ICU admission, and in-hospital mortality

  14 day duration follow-up after ED admission

Study Arms (1)

Blunt Chest Trauma group

The Blunt Chest Trauma Cohort comprises all consecutive adult patients (≥18 years) presenting with blunt chest trauma to the Emergency Department of Assiut university between October 2025 and October 2026. Patients meeting inclusion criteria will be enrolled prospectively and followed throughout their hospital stay to record clinical course and outcomes. At presentation both the STUMBL and TTSS scores will be calculated for each patient using standard definitions. The cohort will be analyzed as a single group to evaluate the predictive performance of each score for predefined outcomes (morbidity and mortality)

Diagnostic Test: Chest X-Ray; Diagnostic Test: Computed Tomography (CT) Chest (with or without contrast)

Interventions

Chest X-Ray DIAGNOSTIC_TEST

First-line imaging for suspected rib fractures, hemothorax, pneumothorax, or pulmonary contusion

Blunt Chest Trauma group

Computed Tomography (CT) Chest (with or without contrast) DIAGNOSTIC_TEST

Gold standard for detecting: Rib fractures (especially multiple and posterior). Pulmonary contusions and lacerations. Hemothorax, pneumothorax, hemopericardium. Pleural or mediastinal injuries

Blunt Chest Trauma group
