The German hospital malnutrition study

Area of Science:

• Clinical Nutrition
• Hospital Medicine
• Geriatrics
• Oncology

Background:

• Malnutrition is common in severe chronic diseases, leading to poorer patient outcomes.
• Data on the prevalence and impact of hospital malnutrition in Germany were previously lacking.
• Understanding malnutrition's scope is crucial for improving patient care in healthcare settings.

Purpose of the Study:

• To determine the prevalence of malnutrition among hospitalized patients in Germany.
• To identify risk factors associated with hospital malnutrition.
• To analyze the impact of nutritional status on hospital length of stay.

Main Methods:

• Nutritional status assessed using Subjective Global Assessment (SGA) and anthropometric measurements.
• Study included 1,886 consecutively admitted patients across 13 German hospitals.
• Statistical analyses performed to identify risk factors and impact on hospital stay.

Main Results:

• Malnutrition diagnosed in 27.4% of patients via SGA; low muscle/fat areas noted in 11.3%/17.1%.
• Prevalence highest in geriatric (56.2%), oncology (37.6%), and gastroenterology (32.6%) departments.
• Malnutrition linked to a 43% increase in hospital stay; independent risk factors include higher age, polypharmacy, and malignancy.

Conclusions:

• Approximately 27% of German hospital patients are malnourished, impacting clinical outcomes.
• Higher age, malignancy, and polypharmacy are significant contributors to malnutrition.
• Initiating adequate nutritional support is essential for optimizing patient recovery and outcomes.
