Summary
Critically ill patients need more protein for recovery, yet current intake is insufficient. Improving protein delivery in intensive care units (ICUs) is crucial for better patient outcomes.
Area of Science:
- Clinical Nutrition
- Critical Care Medicine
- Metabolic Support
Background:
- Exogenous protein/amino acid supplementation shows promise for improving recovery in critically ill patients.
- Expert consensus recommends 2.0-2.5 g/kg/d protein for critically ill patients.
- Current data indicate protein is underprescribed and underdelivered in this population.
Purpose of the Study:
- To highlight the discrepancy between recommended and actual protein intake in critically ill patients.
- To emphasize the need for process improvement initiatives to increase protein delivery.
- To identify future research directions for optimizing protein administration and functional outcomes.
Main Methods:
- Review of published evidence on protein supplementation in critical illness.
- Analysis of International Nutrition Survey data regarding protein prescription and delivery.
- Discussion of current practices and future research needs.
Main Results:
- Critically ill patients are not receiving the recommended protein intake.
- Protein administration primarily relies on enteral nutrition (EN), despite other available methods.
- There is a significant gap between protein needs and actual delivery in ICUs.
Conclusions:
- Ongoing efforts are needed to increase protein intake in critically ill patients to prevent potential harm.
- Future research should focus on optimal protein dosing, timing, composition, and patient selection.
- Combining adequate protein delivery with early mobility and exercise may enhance functional outcomes for survivors.
