The value of improved frailty index and sleep quality in predicting postoperative delirium in elderly patients
Objective Exploring the value of improved frailty index(mFI)and sleep quality index(PSQI)scores in predicting postoperative delirium in elderly patients.Methods A retrospective analysis of 322 elderly surgical patients was conducted between August 2020 and August 2023.They were divided into two groups based on the presence or absence of postoperative delirium,namely the occurrence group(n=28)and the non-occurrence group(n=294).The general data of the two groups were compared,and independent factors affecting postoperative delirium were ana-lyzed through binary logistic regression.At the same time,the predictive value of mFI score and PSQI score was ana-lyzed through ROC curve analysis.Results After binary logistic regression analysis,age＞75 years old,PSQI score,and mFI score were independent factors affecting postoperative delirium in elderly patients(P＜0.05).According to ROC curve analysis,the AUC predicted by PSQI score and mFI score for postoperative delirium in elderly patients is 0.926 and 0.827,respectively.Conclusion PSQI score and mFI score can predict the occurrence of postoperative de-lirium in elderly patients,and have high utilization value.
