Malnutrition in German hospitals remains a critical, often overlooked medical crisis, with prevalence rates between 30 and 70 percent. To address this, the Hannover Medical School (MHH) and Techniker Krankenkasse (TK) have launched a new quality contract to mandate systematic screening and targeted nutritional therapy for hospitalized patients.
Clinical Essentials of Hospital-Based Nutrition
- Systematic Screening: Patients undergo mandatory nutritional assessments upon admission, during their stay, and at discharge to identify deficits early.
- Defining Malnutrition: It is not merely low body weight; it is a persistent deficiency in proteins, vitamins, or minerals that impairs physical and cognitive function.
- Targeted Intervention: The contract provides specific funding for personalized nutritional therapy, ensuring that identification leads directly to clinical action.
The Discrepancy Between Patient Risk and Clinical Care
While the clinical prevalence of malnutrition in hospitals is high, documentation remains alarmingly low. According to research conducted by the MHH and the University Hospital Würzburg, only 1.16 to 1.30 percent of inpatients receive a formal diagnosis of malnutrition. Even among those diagnosed, documentation shows that only 2.77 to 4.45 percent receive a structured nutritional therapy plan.
Data from the Berlin Institute for Applied Health Research indicates that patients with diagnosed malnutrition face a 90-day mortality rate of 18.2 percent, compared to 7.3 percent in a matched control group. The readmission rate within 90 days reaches 44.9 percent for malnourished patients, significantly higher than the 37.8 percent observed in the control group.
Financial and Regulatory Implications of the Quality Contract
The analysis revealed that health costs for a patient within one year of a malnutrition diagnosis average 18,052 euros—approximately 4,396 euros higher than those of a comparable patient without such a diagnosis. PD Dr. Katharina Hupa-Breier, who leads the interdisciplinary nutritional medicine team at the MHH clinic for Gastroenterology, Hepatology, Infectiology, and Endocrinology, emphasizes that these figures reflect a systemic failure to prioritize nutritional status as an essential component of recovery.
The new quality contract between MHH and TK aims to close this gap by providing specific financial reimbursements for nutritional screening and counseling. This initiative is particularly timely, as the German Federal Joint Committee (G-BA) received a mandate in April 2026, under the Hospital Reform Adjustment Act, to establish quality assurance measures for the detection and treatment of malnutrition.
| Metric (90-Day Window) | Malnourished Patients | Control Group |
|---|---|---|
| Mortality Rate | 18.2% | 7.3% |
| Readmission Rate | 44.9% | 37.8% |
Underlying Conditions Cause Complex Clinical State of Malnutrition
Malnutrition is a complex clinical state often secondary to underlying conditions such as oncological diseases, gastrointestinal disorders, or chronic infections.
Broadening the Scope of Nutritional Medicine
Klinikdirektor Prof. Dr. Heiner Wedemeyer notes that this agreement elevates nutritional medicine to a central pillar of patient care.
