GNRI and PNI to predict short-term outcomes in older adults with multiple rib fractures

Official title: Association of the Geriatric Nutritional Risk Index and Prognostic Nutritional Index With Short-Term Clinical Outcomes in Older Adults With Multiple Rib Fractures Presenting to the Emergency Department After Isolated Blunt Thoracic Trauma: A Prospective Observational Cohort Study

Run by Ankara Etlik City Hospital · NCT07823712 · Data updated 2026-11-12

This study tests whether GNRI and PNI, calculated from routine data, can help predict short-term outcomes for adults 65 and older with several rib fractures after blunt chest trauma.

Is this trial a fit for you?

Likely a good fit

Adults aged 65 years or older with isolated blunt thoracic trauma and more than three radiologically confirmed rib fractures, presenting within the emergency department and able to provide consent.

Probably not a fit

Patients with penetrating trauma, single rib fracture, polytrauma, significant comorbidities affecting nutrition markers, or missing data may not benefit from the prognostic assessment.

What this trial studies

This is a prospective, single-center, observational cohort study conducted in the Emergency Department at Ankara Etlik City Hospital. It will enroll adults aged 65 or older with isolated blunt thoracic trauma and more than three rib fractures, collecting routine clinical, laboratory, anthropometric, imaging, and follow-up data. The main goal is to see if GNRI and PNI can predict a composite short-term poor outcome, including death, ICU admission, ventilation, pneumonia, atelectasis, chest tube insertion, or hospital stay of seven days or more. Secondary analyses will look at the individual components of the composite outcome. No experimental interventions are used beyond standard care.

Why it matters

Potential benefit: If successful, GNRI and PNI could help clinicians identify high-risk patients early and tailor monitoring and care accordingly.

How similar studies have gone: Other studies have shown the prognostic value of nutritional indices in trauma and older populations, but this study applies GNRI and PNI specifically to isolated rib fracture scenarios in older adults.
