Palliative care units in The Netherlands: changes in patients' functional status and symptoms.

Although efforts have been made to define optimal terminal care in palliative care units (PCUs), comprehensive longitudinal evaluations of care outcomes in PCUs at the end of life are scarce. In this study, changes in functional status (assistance needed for walking, and toilet use) and symptoms (pain, nausea, shortness of breath, depression, and anxiety) were assessed in all patients (n=355) admitted to 10 PCUs in Dutch nursing homes. Outcomes were measured at 24 hours, 48 hours, one week, and two weeks before death, and at PCU admission. Results show that functional status deteriorated from admission to one week before death, but most symptoms did not worsen in the last three weeks before death. Decreases in pain, anxiety, and nausea were observed. The results suggest that the care provided in the PCUs stabilized the symptom levels. Patients who die between two and four weeks appeared to have more favorable symptom change patterns than patients who die within two weeks, which supports the recommendation to admit eligible patients in earlier phases of their disease. Limitations include the use of proxy measures and some forms of selection bias, which may lead to underestimation of symptom levels.
