Geriatric Nutritional Risk Index and Postoperative Delirium Association Meta-Analysis

A meta-analysis document summarizing the association between the Geriatric Nutritional Risk Index (GNRI) and postoperative delirium (POD). The analysis includes 12 cohort studies involving 12,332 surgical patients and was authored by Dandan Han. The document was last updated on April 23, 2026.

Use Cases

• Assessing the relationship between preoperative nutritional status and delirium risk based on pooled risk ratios.
• Informing clinical guidelines for geriatric patient screening using the GNRI metric.
• Conducting subgroup analyses on factors like patient age and GNRI cutoff values.
• Supporting systematic review methodologies for surgical outcomes research.

Strengths

• Analysis is based on 12 cohort studies with a total of 12,332 patients.
• Includes specific statistical results, such as a pooled risk ratio of 1.62 (95% CI: 1.34–1.96).
• Study protocol was prospectively registered (PROSPERO CRD420261335609).
• Performed subgroup and meta-regression analyses to explore heterogeneity.

Limitations

• The primary data file is a 17.8 KB DOCX document, which is a summary report rather than a raw dataset.
• Row count and column-level data for the underlying studies are unknown.
• Data freshness should be verified as the last update is in the future (2026).
