It has been widely reported that among relatives of palliative care patients, there is a high incidence of mental distress, depression, anxiety, sleep disturbance, fear and despair. The maintain of hope and spiritual well-being are important in dealing with this difficult process. Accordingly, nursing care is important, which supports the hope and spiritual well-being of patients' relatives.
