    A nomogram was developed to predict postoperative delirium (POD) in elderly patients with intertrochanteric fractures.

  • 2

    The study included 248 patients aged ≥60 years who received low-dose dexamethasone before surgery.

  • 3

    Three independent predictors of POD were identified: age, preoperative monocyte count, and postoperative ICU transfer.

  • 4

    The nomogram demonstrated good discriminative ability with an AUC of 0.803 and accuracy of 0.843.

  • 5

    This model aims to facilitate early identification of high-risk patients and support targeted preventive strategies.
