    ObjectivesTo review current evidence on using the geriatric nutritional risk index (GNRI) in predicting postoperative delirium (POD) in elderly patients.MethodsThe literature search was performed in core databases to include all the cohort studies on the association between GNRI and risk of POD for further meta-analysis.ResultsA total of 6 studies with 4242 patients underwent this meta-analysis, which showed that the risk of POD was higher in patients with moderate and high GNRI than the ones with low GNRI (odds ratio [OR]=2.04, 95% confidence interval [CI] [1.58, 2.64], p<0.001), and moderate and high GNRI significantly increased the risk of POD in patients of 60 to 75 years or above [OR=1.98, 95%CI (1.49, 2.62), p<0.001; OR=2.79, 95%CI (1.38, 5.64), p=0.004, respectively].ConclusionTherefore, moderate and high GNRI increased the risk of POD in elderly patients.Copyright: © Saudi Medical Journal.
