A phenomenological three-parameter model for predicting the extent of outpatient palliative care

Whether a patient receives general or specialized outpatient palliative cancer care rarely follows clear criteria, leading to undertreatment or overtreatment. Detailed scores exist to predict prognosis, but not treatment requirements, leaving caregivers to follow their intuition. As a phenomenological indicator incorporating possibly important subjective information, intuition may in fact be a helpful tool. In this prospective observational study, a score to estimate three global dimensions of patients' resources was applied: Medical prognosis, feeling of strength and feeling of support. The score results were correlated with the actual amount and effort of care required during the subsequent palliative care time. This phenomenological score correlated well with the performance index and the Hospice and Palliative care Evaluation score. Whilst various individual items correlated significantly with the score or its constituent parameters, there was no uniform coherent pattern, reflecting the complexity of palliative care and the potential value of this predictive tool.
