Financial implications of malnutrition

Area of Science:

• Clinical Nutrition
• Hospital Medicine
• Health Economics

Background:

• Protein-energy malnutrition (PEM) affects 30-50% of hospitalized patients, independent of other conditions.
• PEM results from inadequate nutrient intake, leading to weight loss, functional decline, and impaired immunity.
• It exacerbates existing chronic conditions and increases vulnerability to acute metabolic stress.

Purpose of the Study:

• To analyze the financial implications of malnutrition and nutritional therapy in hospitalized patients.
• To present a model for evaluating the economic impact of PEM and its management.
• To highlight the cost-effectiveness of early nutrition support versus treating complications.

Main Methods:

• Review of existing literature on PEM prevalence, consequences, and costs.
• Analysis of financial data related to hospital length of stay (LOS), complications, and nutrition interventions.
• Development of a financial model to compare costs of untreated PEM versus nutrition support.

Main Results:

• PEM significantly increases hospital morbidity, mortality, and length of stay (LOS).
• Complications associated with PEM include pneumonia, sepsis, surgical site infections, and delayed wound healing.
• The costs of PEM extend beyond direct medical expenses to include nutrition support and complication management.

Conclusions:

• PEM represents a significant financial burden and a controllable liability for hospitals.
• Early identification and intervention with nutrition support can mitigate costs associated with PEM.
• A comprehensive financial analysis must consider both the costs of intervention and the avoided costs of complications and extended LOS.
