Are We Underestimating the Morbidity of Single Rib Fractures?

Area of Science:

• Trauma surgery
• Critical care medicine
• Health services research

Background:

• Multiple rib fractures are linked to poor outcomes.
• The impact of isolated single rib fractures (SRF) on morbidity and mortality is not well understood.
• Identifying high-risk patients with SRF is crucial for targeted interventions.

Purpose of the Study:

• To model adverse outcomes following isolated single rib fractures (SRF).
• To identify demographic and comorbidity factors associated with poor outcomes in SRF patients.
• To develop a predictive tool for adverse events after SRF.

Main Methods:

• Utilized the 2016 National Inpatient Sample database.
• Identified patients with SRF from blunt trauma using ICD-10 codes.
• Developed a multivariable model and nomogram to predict adverse composite outcomes (death, pneumonia, tracheostomy, prolonged hospitalization).

Main Results:

• The study included 2,398 patients with isolated SRF.
• An adverse composite outcome occurred in 20.8% of patients.
• The predictive model achieved a C-statistic of 0.700 in the training set and 0.672 in the validation set.

Conclusions:

• Approximately 20% of patients with isolated SRF experience adverse outcomes.
• Patient demographics and existing comorbidities are key predictors of adverse events.
• These findings can guide the identification and triage of high-risk SRF patients for specialized care.
