NutriBest Feeding Recommendation for 73kg Patient
For a 73kg patient whose primary nutrition source is NutriBest, provide approximately 1,971 kcal/day (27 kcal/kg) and 88-110g protein/day (1.2-1.5 g/kg). This assumes the patient is a polymorbid older adult (≥65 years) requiring nutritional support 1.
Energy Requirements
The most recent ESPEN guidelines (2024) provide clear weight-based formulas when indirect calorimetry is unavailable 1:
For older polymorbid patients (≥65 years): Target approximately 27 kcal/kg actual body weight/day for total energy expenditure (TEE)
- For your 73kg patient: 1,971 kcal/day
Alternative calculation: Resting energy expenditure (REE) can be estimated at 18-20 kcal/kg/day, then add activity/stress factors
- REE: 1,314-1,460 kcal/day, then multiply by appropriate factor (typically 1.2-1.5)
Important Caveats:
- If the patient is severely underweight, increase target to 30 kcal/kg/day (2,190 kcal), but advance slowly to avoid refeeding syndrome 1
- These formulas serve as starting points only; prediction equations have low accuracy in polymorbid patients 1
- Monitor phosphate daily when initiating feeding to detect refeeding syndrome (30% drop requires feeding reduction) 2
Protein Requirements
Target 1.2-1.5 g protein/kg body weight/day as a Grade A recommendation 1:
- For your 73kg patient: 88-110g protein/day
- This is cost-effective and prevents body weight loss, reduces mortality, complications, hospital readmissions, and improves functional outcomes and quality of life 1
Critical Exception:
- If eGFR <30 ml/min/1.73m² and NOT on dialysis: Restrict to 0.8 g/kg/day (58g protein) 1
Micronutrients
Ensure NutriBest formula meets daily estimated requirements for all vitamins and trace elements 1. If documented or suspected deficiencies exist, provide specific repletion 1.
Special Considerations
If pressure ulcers present: Add arginine, glutamine, and β-HMB to accelerate healing 1
If bowel dysfunction: Consider fiber-enriched formulas (mixture of soluble/insoluble) 1
Drug interactions: Establish pharmacist-assisted management plan for potential drug-nutrient interactions in polymorbid patients 1
Monitoring Strategy
Track functional indices rather than just nutritional parameters, as these better predict survival and quality of life in polymorbid patients 1. Assess tolerance, adequacy of delivery (percentage of goal achieved), and aspiration risk 3.
The weight-based approach is pragmatic and evidence-based for polymorbid patients, though clinicians should recognize considerable individual variation exists around these estimates 1.
