Geriatric Nutritional Risk Index and ICU Admission Risk in Gastrointestinal Tumor Surgery

A retrospective cohort study analyzed 9,045 gastrointestinal tumor surgery patients from the INSPIRE database to investigate the relationship between preoperative Geriatric Nutritional Risk Index (GNRI) and postoperative ICU admission risk. The study used multivariable logistic regression and generalized additive models, identifying a non-linear relationship with a critical threshold at GNRI=89. The dataset was authored by Wei-De Lin and last updated on 2026-05-28.

Use Cases

• Predicting ICU admission risk based on preoperative nutritional status.
• Developing risk stratification tools using the GNRI threshold of 89.
• Analyzing non-linear relationships between nutritional indices and surgical outcomes.

Strengths

• Analysis based on a cohort of 9,045 patients.
• Results include specific risk ratios (e.g., 2.01-fold higher risk for GNRI < 82).
• Study employed multivariable regression and sensitivity analyses to verify robustness.

Limitations

• The dataset is described in a 17.2 KB DOCX file, suggesting limited raw data scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
