Nutritional Risk and Hospital Stay Data for 896 Upper Gastrointestinal Disease Patients

896 patient records from a single-center retrospective study at the First Medical Center of PLA General Hospital were analyzed to assess predictors of long hospital stays. The data includes demographic information, lifestyle factors, primary diagnosis, comorbidities, laboratory test values, and length of hospital stay (LOHS). The study, authored by Ruiqing Zhu and last updated in June 2026, identified the Nutritional Risk Screening 2002 (NRS2002) score and serum albumin level as independent risk factors for prolonged hospitalization.

Use Cases

• Predicting length of hospital stay based on nutritional risk scores and serum albumin levels.
• Identifying patient risk factors for prolonged hospitalization in upper gastrointestinal disease cohorts.
• Validating the NRS2002 screening tool's predictive performance in a clinical setting.
• Analyzing the relationship between nutritional status and healthcare resource utilization.

Strengths

• Data covers 896 patients with a median age of 61.0 years, providing a substantial clinical cohort.
• Includes a defined outcome measure (long LOHS > 19 days) and validated predictors (NRS2002 score AUC of 0.721).
• Licensed under CC-BY-4.0, allowing for open reuse and redistribution.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single-center retrospective study, which may limit generalizability.
