RESUMEN
PURPOSE: To determine the efficacy of specifically targeted interventions in palliative care, sequential use of the Demoralization Scale (DS) could be a useful approach. This study's main objective was to evaluate the weekly use of the DS for palliative care inpatients. Secondary objectives were the analysis of the DS, self-perceived strain, and personal benefits of the assessment. METHODS: Patients admitted to 3 palliative care units (PCUs) were tested for eligibility and asked to complete the DS weekly. Self-perceived strain was rated on a numeric scale (0-10). Open questions about strain and helpfulness of the survey were asked. RESULTS: Over 10 months, 568 patients were admitted to the PCUs; 193 patients were eligible. A total of 120 patients participated once, of whom only 41 (34.1%) participated at least twice. The mean self-perceived strain caused by the assessment was 1.53 at T1 (N = 117, SD = 2.27, max = 8). CONCLUSIONS: While the single use of the DS in PCUs seems justified in view of the possibility to detect severe demoralization with overall low to moderate strain and self-perceived helpfulness for patients, the feasibility of the sequential use of the DS has to be regarded critically. Our study undermines the complexity of assessing changes in self-reported psychological phenomena with end-of-life patients at a PCU. The most limiting factors for participating twice were that patients were either discharged from hospital or declined further participation.
