Cachexia and nutritional problems play a major role in palliative care. Artificial nutrition such as parenteral nutrition is common but its role and indications in terminal patients remain controversial due to lack of data. Therefore, recommendations are vague. Benefits and risks of parenteral nutrition in palliative care as well as the clinical implementation of the guidelines have not been adequately studied yet.
In this single-centre observational study, 72 palliative care patients were followed for 1 month. Patients with and without parenteral nutrition were analysed regarding venous access complications, oedema, weight and health-related quality of life.
93% of all patients showed reduced food intake. 34 (47%) patients received parenteral nutrition. Parenteral nutrition reduced energy deficit but was not associated with quality of life. Complications with the venous accesses for parenteral nutrition were frequent. A relevant proportion of patients with planned parenteral nutrition received no or only a few days of parenteral nutrition. Moreover, patients with parenteral nutrition showed more frequent and pronounced oedema.
The benefit–risk balance of palliative parenteral nutrition in end-of-life treatment seems to be questionable. In view of the identified risks, parenteral nutrition in end-of-life care should be initiated with caution.
