Quantification of rib fractures by different scoring systems.

Area of Science:

• Trauma Surgery
• Critical Care Medicine
• Orthopedic Surgery

Background:

• Rib fractures are common injuries in trauma patients.
• Existing evaluation systems include Rib Fracture Score (RFS), Chest Trauma Score (CTS), and RibScore (RS).
• Optimal utilization of these scores may vary between different patient demographics.

Purpose of the Study:

• To determine critical values for RFS, CTS, and RS in distinct patient populations (nongeriatric and geriatric).
• To assess the association of these critical values with clinical outcomes such as mortality and length of stay.

Main Methods:

• A retrospective cohort study of 1089 patients with rib fractures was conducted.
• Patients were divided into nongeriatric (n=620) and geriatric (n=469, ≥65 years) groups.
• Outcomes analyzed included mortality, Injury Severity Score (ISS), hospital and ICU lengths of stay (HLOS, ICULOS), mechanical ventilation duration, pneumonia (PN) rate, tracheostomy, and epidural analgesia.

Main Results:

• Critical values identified: RFS (10 nongeriatric, 8 geriatric), CTS (4 nongeriatric, 6 geriatric), RS (1 for both).
• Higher scores correlated with adverse outcomes (mortality, ISS, HLOS, ICULOS, PN, tracheostomy) across both groups (P < 0.05).
• Chest Trauma Score demonstrated the best prediction for pneumonia in geriatric patients (c=0.8).

Conclusions:

• The choice of scoring system should be tailored to the specific patient population and available data.
• Rib Fracture Score is sensitive in the elderly, while Chest Trauma Score is recommended for geriatric patients due to its predictive value for pneumonia.
• RibScore is valuable for assessing severely injured patients with high ISS.
