Research Papers: Nutrition in Patient Recovery & Hospital Diets

1. Individualized Nutritional Support in Hospitalized Patients

• Authors: Schuetz P, Fehr R, Baechli V et al.
• Journal: The Lancet | Year: 2019
• PMID: 31030981
• Type: Multicenter Randomized Controlled Trial
• Summary: This landmark RCT (the EFFORT trial) demonstrated that individualized nutritional support in at-risk medical inpatients significantly reduced adverse clinical outcomes including mortality, complications, hospital readmissions, and loss of functional status compared to standard hospital nutrition. One of the most cited papers in hospital nutrition.

2. Early Enteral vs. Parenteral Nutrition in Critical Care

• Authors: Baik SM, Kim M, Lee JG
• Journal: Nutrients | Year: 2024
• PMID: 39796444
• Type: Systematic Review & Meta-Analysis
• Summary: Compares the route of early nutritional delivery in ICU patients. Findings support early enteral nutrition as the preferred approach to reduce infection rates, ICU length of stay, and complications, reinforcing its role in accelerating recovery.

3. Preoperative Nutrition Therapy

• Authors: Sowerbutts AM, Burden S, Sremanakova J
• Journal: Cochrane Database of Systematic Reviews | Year: 2024
• PMID: 38588454
• Type: Cochrane Systematic Review & Meta-Analysis
• Summary: Evaluates preoperative nutritional interventions in GI surgery patients, assessing effects on postoperative complications, length of stay, and recovery quality. Cochrane gold-standard methodology.

4. Postoperative Nutritional Support

• Authors: Robertson RH, Russell K, Jordan V
• Journal: Cochrane Database of Systematic Reviews | Year: 2025
• PMID: 40084692
• Type: Cochrane Systematic Review & Network Meta-Analysis
• Summary: Assesses different postoperative nutrition strategies after major abdominal surgery, comparing enteral, parenteral, and oral routes for promoting recovery and reducing complications.

5. Supplemental Parenteral Nutrition Timing

• Authors: Gao X, Liu Y, Zhang L et al.
• Journal: JAMA Surgery | Year: 2022
• PMID: 35293973
• Type: Multicenter RCT
• Summary: Directly compares the timing of parenteral nutrition initiation in surgical patients. Early supplemental PN was associated with faster recovery of nutritional status and fewer complications, with implications for hospital diet protocols.

6. Nutritional Assessment in Stroke Patients

• Authors: Mancin S, Sguanci M, Andreoli D
• Journal: International Journal of Nursing Studies | Year: 2024
• PMID: 39043111
• Type: Systematic Review
• Summary: Reviews evidence for nutritional screening and assessment tools in acute stroke, a population highly vulnerable to hospital malnutrition. Relevant to nursing practice and hospital diet planning.

7. Augmented Protein Delivery in Critical Illness

• Authors: Summers MJ, Chapple LS, Karahalios A et al.
• Journal: JAMA | Year: 2025
• PMID: 40495743
• Type: Multicenter RCT
• Summary: A very recent (2025) large RCT examining whether higher enteral protein delivery in critically ill patients improves outcomes. Highly relevant to current hospital nutrition guidelines and ICU diet protocols.

8. Prehabilitation (Nutrition + Exercise Before Surgery)

• Authors: McIsaac DI, Kidd G, Gillis C
• Journal: BMJ | Year: 2025
• PMID: 39843215
• Type: Network Meta-Analysis
• Summary: Analyzes the contribution of nutritional components within multimodal prehabilitation programs to surgical recovery, isolating the specific benefit of nutrition optimization before hospital admission.

9. Glycemic Control in Hospital (Nutrition-Related)

• Authors: Honarmand K, Sirimaturos M, Hirshberg EL
• Journal: Critical Care Medicine | Year: 2024
• PMID: 38240484
• Type: Systematic Review / Practice Guideline
• Summary: Covers glycemic management in critical illness - closely tied to nutritional support since hospital feeding directly affects blood glucose and outcomes. Current SCCM guidelines.
