Classification of incidental findings in polytrauma computed tomography

Area of Science:

• Radiology
• Emergency Medicine
• Trauma Surgery

Background:

• Whole-body computed tomography (WBCT) is standard for trauma patients.
• Incidental findings (IFs) are frequent but often underestimated in WBCT.
• Standardized analysis and classification of IFs are crucial for patient outcomes and healthcare resource management.

Purpose of the Study:

• To develop and validate a feasible classification system for incidental findings (IFs) in WBCT scans.
• To standardize the interpretation of IFs in polytrauma patients.
• To provide a framework for clinical management based on IF severity.

Main Methods:

• Retrospective analysis of 1475 polytrauma patients from two maximum care hospitals.
• Review of medical reports and WBCT scans for incidental findings (IFs).
• Classification of 511 identified IFs into 5 severity categories based on literature analysis.

Main Results:

• Incidental findings (IFs) were present in 83.9% of patients.
• Older and female patients showed a higher incidence and severity of IFs.
• 24% of IFs required monitoring, clarification, or immediate treatment (Categories 3-5).

Conclusions:

• Incidental findings (IFs) in WBCT scans are as common as trauma-related injuries.
• A standardized classification system, IF-RADS (Incidental Finding - Reporting and Data System), is proposed for IFs in WBCT.
• Standardized IF interpretation and classification are essential for optimal patient care and healthcare system efficiency.
