Table 3_Preoperative low Geriatric Nutritional Risk Index increases intensive care unit ad

A retrospective cohort study analyzed 9,045 patients undergoing gastrointestinal tumor surgery 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 postoperative intensive care unit admission risk.

Use Cases

• Predicting postoperative ICU admission risk based on preoperative Geriatric Nutritional Risk Index scores.
• Identifying a critical nutritional threshold (GNRI=89) for non-linear risk modeling in surgical outcomes.
• Stratifying patients into categorical risk groups (e.g., GNRI < 82) for targeted perioperative care planning.
• Validating the robustness of the GNRI-ICU association through subgroup and sensitivity analyses.

Strengths

• Analysis is based on a cohort of 9,045 patient records.
• Results include specific risk ratios, such as a 2.01-fold higher ICU risk for the severe nutritional risk group.
• Identifies a precise, statistically significant threshold (GNRI=89) for non-linear risk changes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (16.5 KB), suggesting it contains summary or analysis results rather than raw patient records.
