Table 1_Preoperative low Geriatric Nutritional Risk Index increases intensive care unit ad

A retrospective cohort study of 9,045 patients undergoing gastrointestinal tumor surgery, sourced from the INSPIRE database. The research, authored by Wei-De Lin and last updated in May 2026, investigates the relationship between preoperative Geriatric Nutritional Risk Index (GNRI) scores and the risk of postoperative intensive care unit admission. It identifies a non-linear relationship with a critical threshold at GNRI=89 and a 2.01-fold higher risk for patients with GNRI < 82.

Use Cases

• Predicting ICU admission risk based on preoperative Geriatric Nutritional Risk Index scores.
• Analyzing non-linear relationships between nutritional status and postoperative complications.
• Developing risk stratification models for patients undergoing gastrointestinal tumor surgery.
• Validating the GNRI as a clinical tool for perioperative assessment.

Strengths

• Dataset includes 9,045 patient records, providing a substantial sample size for analysis.
• Analysis includes multivariable logistic regression, generalized additive models, and subgroup/sensitivity analyses, suggesting methodological rigor.
• Identifies a specific, clinically actionable threshold (GNRI=89) and risk stratification (GNRI < 82).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or institutional bias inherent to the INSPIRE database.
