Medical Nutrition Therapy (MNT) for Malnutrition Systematic Review (2023-24)
Welcome to the Medical Nutrition Therapy for Adults with Malnutrition Systematic Review
Protein-energy malnutrition (PEM), also known as undernutrition, is a cause and consequence of diseases and conditions and can impact anyone. PEM is defined as inadequate intake of protein and/or calories that results in loss of fat stores. The aim of this systematic review and meta-analysis was to evaluate the effect of medical nutrition therapy (MNT) provided by a dietitian on adults with PEM. The project team focused on the following health outcomes:
- Nutrition status
- Mortality
- Length of stay
- Hospital readmissions
- Quality of Life
- Weight
- Physical Function
- Cost-Effectiveness
Key Findings:
Findings suggest that MNT may reduce the length of stay, increase weight, and improve quality of life in inpatients with protein-energy malnutrition. However, not all of the included studies and study participants contributed to each outcome analysis (low certainty of evidence). The review indicates that the impact of MNT on nutrition status, mortality, and other outcomes is largely uncertain, with conflicting results across study types and very low to low certainty of evidence for most outcomes. Improved accuracy of PEM diagnosis will enable timely MNT intervention by dietitians, appropriate nutrition strategies, and proper documentation to facilitate improved health outcomes.
