Risk factors for postoperative delirium in elderly urological patients: A meta-analysis

Abstract

Background: Avoiding postoperative delirium (POD) can have a significant detrimental effect on the rehabilitation and prognosis of elderly urological patients. It is necessary to explore the risk factors associated with POD in elderly urology to provide a basis for clinical recognition of delirium. Methods: For relevant studies, we comprehensively searched Embase, MEDLINE, Ovid, PubMed, Scopus, The Cochrane Library, and Web of Science. The search deadline was September 2021. Results: We identified 2046 studies, 8 of which were included in the ultimate analysis. A total of 8 articles, including 356 cases in the delirium group and 1813 cases in the non-delirium group, were included in the relevant literature. The 2 groups mentioned above differed significantly in the following factors: history of delirium (odds ratio [OR]=6.98, 95% confidence interval [CI]: 1.63-29.86, P=.009); Preoperative use of psychotropic drugs (OR=1.97, 95% CI: 1.11-3.52, P=.02); age (OR=3.10, 95% CI: 2.08-4.12, P
