研究问题
The model should accordingly be read as a preliminary bedside screening model, not a comprehensive etiological risk model; multi-variable prospective cohorts are needed to test whether the omitted domains add performance.Several limitations merit emphasis.
方法
Despite its clinical importance, POD prediction in elderly hip fracture patients remains inadequate.；In this study, we sought to develop a simplified rule-out screening model using only information immediately available at the bedside upon emergency admission.；We prioritized high negative predictive value to safely identify low-risk patients who may not require intensive delirium prevention measures.Materials and methodsStudy design and populationThis single-center retrospective cohort study included patients aged >=60 years who underwent hip fracture surgery at Chengdu Fifth People’s Hospital between January 2019 and August 2023.
核心结论
The Nagelkerke R-squared of 0.241 indicates that these three variables explain a modest proportion of POD variance, consistent with the multifactorial nature of delirium.
局限
This estimate, however, warrants explicit caution.；The model should accordingly be read as a preliminary bedside screening model, not a comprehensive etiological risk model; multi-variable prospective cohorts are needed to test whether the omitted domains add performance.Several limitations merit emphasis.；This approach risks missing hypoactive delirium episodes, which would bias estimates toward the null, so the reported associations are likely conservative; differential misclassification cannot, however, be excluded, and conclusions are worded accordingly.
