Background

Hip fracture is a common and serious injury in older adults, with an increasing incidence as the population ages.

Purpose

The purpose of this study was to develop and validate a nomogram to predict the risk of postoperative pneumonia in geriatric patients with hip fracture.

Methods

We conducted a retrospective cohort study of geriatric patients who underwent hip fracture surgery in our hospital between Feb 2015 and Feb 2024.

n = 1296 patients

Results

AUROC of 0.874, closer to 1.0 means better discrimination between pneumonia and no pneumonia

0.874AUC

Training set

0.84AUC

Validation set

More results

The incidence of postoperative pneumonia was 9.1%.

“

Conclusion · 1 of 2

The nomogram is a well-calibrated and discriminative tool that can be used to predict the risk of postoperative pneumonia in geriatric patients with hip fracture.

Conclusion · 2 of 2

The nomogram may be useful for identifying patients who may benefit from preventive measures.
