Malnutrition management and the application of medical nutrition therapy in hospitalized patients at the end of life

Objectives: (1) To determine the prevalence of malnutrition risk in hospitalized patients at the end of life (EOL), (2) to evaluate which nutritional interventions are administered in hospitalized end-of-life patients with malnutrition risk and (3) to assess the association of end-of-life care and the administration of medical nutrition therapy in patients with malnutrition risk. Design: Cross-sectional multi-center study Setting: Hospital Participants: Hospitalized adult patients Measurements: Based on the valid and reliable questionnaire of the Nursing Quality Measurement 2.0 (LPZ), the parameters of demographic data, medical diagnoses, end-of-life phase, care dependency, malnutrition risk according to the Malnutrition Universal Screening Tool (MUST) and nutritional interventions conducted in patients at risk of malnutrition were assessed. Descriptive statistics and statistical tests were conducted. Logistic regression models were established to identify odds ratios (OR) and confidence intervals (CI) for the association of end-of-life care and the provision of medical nutrition therapy. This was done separately for oral nutritional supplements (ONS), enteral nutrition and parenteral nutrition as the respective dependent variables. Results: Of all 12,947 participants, 706 (5.5%) were in an end-of-life phase. The prevalence of malnutrition risk in end-of-life patients was 41.1% compared to 24.7% in other patients (p < 0.001). End-of-life patients with malnutrition risk received more nutritional interventions than other patients with malnutrition risk. The regression models showed that being at the end of life (CI 1.30, 2.63; p < 0.001), being treated by a dietitian (OR 6.02; CI 4.86, 7.45; p < 0.001), suffering from dementia (OR 1.85; CI 1.10, 3.12; p = 0.02) or cancer (OR 1.56; CI 1.25, 1.96; p < 0.001) increased the chance of receiving oral nutritional supplements. For receiving parenteral nutrition, being at the end of life (OR 1.68; CI 1.04, 2.71; p = 0.04), being treated by a dietitian (OR 5.80; CI 4.07, 8.25; p < 0.001), surgery within the previous two weeks (OR 1.58; CI 1.09, 2.30; p = 0.02), younger age (OR 0.99; CI 0.98, 1.00; p = 0.04), care dependency (OR 0.97; CI 0.96, 0.98; p < 0.001), suffering from a disease of the digestive system (OR 2.92; CI 2.07, 4.11; p < 0.001) or cancer (OR 2.44; CI 1.71, 3.49; p < 0.001) were independent predictors. Being at the end of life did not influence the application of enteral nutrition. Conclusion: This study showed that nutritional interventions are often applied in end-of-life patients admitted to general hospitals. Being at the end of life was positively associated with the application of oral nutritional supplementation and parenteral nutrition. This data does not allow a conclusion about the appropriateness of using medical nutrition therapy in this study sample. Judging the appropriateness of medical nutrition therapy at the end of life is challenging because of the high variability of prognostication as well as the wishes and needs of the specific patients and their relatives that influences the appraisal of adequate interventions. Every decision about nutrition and hydration in end-of-life patients should be a shared decision and be based on advanced care planning principles.
