Symptom burden in malignant and non-malignant disease on admission to a palliative care unit

Abstract

BackgroundThere is increasing recognition that patients with non-malignant diseases have comparable physical and psychosocial symptom burden to patients with cancer. There is currently limited data directly comparing symptom burden between these patient groups.ObjectiveTo investigate differences in symptom burden between patients with malignant and non-malignant conditions admitted to a palliative care unit (PCU).MethodA cross-sectional study involving 186 patients admitted to a PCU was undertaken. Patients were dichotomised into malignant or non-malignant disease categories. Symptom burden at admission was assessed using the Symptom Assessment Scale and Palliative Care Problem Severity Score. Group differences in symptoms were analysed using univariate and multivariate approaches.ResultsOne hundred patients (53.8%) had cancer, with upper gastrointestinal the most common type (18.0%). Among the 86 patients with non-malignant disease, neurological conditions were most prevalent (40.7%). Patients admitted with non-malignant diseases were older, more functionally impaired and more likely to be deteriorating or terminal. A malignant diagnosis was associated with a higher likelihood of clinician-assessed pain, patient-assessed pain, fatigue, psychological/spiritual symptoms and other symptoms. However, when adjusted for confounders, disease category ceased to be a significant predictor of symptom burden. Younger patients experienced worse pain and patients in terminal phase experienced less symptom burden.ConclusionSymptom burden was similar between patients with malignant and non-malignant disease after adjustment for confounders. Further research is needed to understand the palliative care needs of patients with non-malignant disease.
