    Postoperative cognitive dysfunction (POCD) is linked to adverse outcomes, necessitating effective prediction models for risk assessment.

  • 2

    Thirteen studies with 14 prediction models for POCD were included, primarily using logistic regression and machine learning techniques.

  • 3

    Common predictors of POCD include age and preoperative hemoglobin concentration, with most predictors measured preoperatively.

  • 4

    High risk of bias in models was attributed to small sample sizes and lack of external validation, limiting their clinical applicability.

  • 5

    Future research should focus on larger cohorts, longitudinal predictors, and rigorous external validation to enhance POCD model utility.
