Introduction Recent empirical research on palliative care for psychiatric patients is lacking. Aim The aim of this study was to explore nurses' experiences with and identify barriers to providing palliative care to psychiatric patients in Dutch mental health facilities. Methods Mixed-methods; 137 nurses working in Dutch mental health facilities completed a survey. Nine participated in in-depth interviews. Results Thirty-six percent of nurses had experience with providing palliative care to psychiatric patients with physical co-morbidity in the past 2 years. Of all patients, 63% received physical care before death, 46% psychosocial care and 33% spiritual care. In 91% of all cases, care was provided by multidisciplinary teams. Patient characteristics and little attention to palliative care were barriers for timely and adequate palliative care. Discussion In palliative care for psychiatric patients, there is more attention for psychosocial and spiritual care compared to palliative care for patients without psychiatric disorders. Yet there are barriers to adequate palliative care provision. Implications for practice Educating psychiatric nurses about palliative care and close collaboration between physical and mental health care are crucial to address the palliative care needs of psychiatric patients. Since mental health care is increasingly provided ambulatory, palliative care for psychiatric patients outside mental health facilities should be closely monitored.
