Meta AnalysisThe Association of Preoperative Frailty and Postoperative Delirium: A Meta-analysis.
Both frailty and postoperative delirium (POD) are common in elective surgical patients 65 years of age and older. However, the association between preoperative frailty and POD remains difficult to characterize owing to the large number of frailty and POD assessment tools used in the literature, only a few of which are validated. Furthermore, some validated frailty tools fail to provide clear score cutoffs for distinguishing frail and nonfrail patients. We performed a meta-analysis to estimate the relationship between preoperative frailty and POD. ⋯ This meta-analysis provides evidence for a significant association between preoperative frailty and POD in elective surgical patients age 65 years or older.
