This qualitative study explored the views of spouse carers in relation to the emotional impact of caring for a partner with a chronic or terminal illness. Findings indicate that these carers experienced a whole range of feelings and emotions, which impacted on their health and well-being. They included fatigue, stress, distress, anxiety, depression, feelings of isolation and suicidal thoughts. These were particularly profound around the time of diagnosis, end of treatment, during a relapse and most particularly around the time of death. An increasing number of terminally ill people are now expressing a preference to be cared for at home. The potential risks to the health of caregivers therefore need to be taken into account.
