BACKGROUND Many nursing students are not prepared to encounter death and care for patients who are at the end of life as newly educated nurses. The Frommelt Attitude Toward Care of Dying Scale (FATCOD) has been used to assess nursing students' attitudes during their education and changes have been noted. OBJECTIVE To examine nursing students' attitudes towards care of dying patients before and after a course in palliative care. METHODS A descriptive study with a pre and post design. METHODS Nursing students (n = 73) enrolled in a mandatory palliative course in the nursing programme at a Swedish university. METHODS Data were collected before and after a palliative care course using FATCOD and qualitative open-ended questions. Data from FATCOD were analysed using descriptive and analytical statistics. The open-ended questions were analysed with qualitative content analysis. RESULTS The students' mean scores showed a statistically significant change toward a more positive attitude toward care of dying. Students with the lowest pre-course scores showed the highest mean change. The qualitative analysis showed that the students had gained additional knowledge, deepened understanding, and increased feelings of security through the course. CONCLUSIONS A course in palliative care could help to change nursing students' attitudes towards care of patients who are dying and their relatives, in a positive direction. A course in palliative care is suggested to be mandatory in nursing education, and in addition to theoretical lectures include learning activities such as reflection in small groups, simulation training and taking care of the dead body.
