Background: A do-not-resuscitate (DNR) order is an important end-of-life decision. In Taiwan, family caregivers are also involved in this decision-making process. This study aimed to explore the concerns and experiences regarding DNR decisions among caregivers in Taiwan. Methods: Qualitative study was conducted. Convenience sampling was used, and 26 caregivers were recruited whose patients had a DNR order and had received hospice care or hospice home care. Semi-structured interviews were used for data collection, including the previous experiences of DNR discussions with the patients and medical staff and their concerns and difficulties in decision-making. The data analysis was based on the principle of thematic analysis. Findings: Four themes were identified: (1) Patients: The caregivers respected the patients' willingness and did not want to make them feel like "giving up." (2) Caregivers' self: They did not want to intensify the patients' suffering but sometimes found it emotionally difficult to accept death. (3) Other family members: They were concerned about the other family members' opinions on DNR orders, their blame, and their views on filial impiety. (4) Medical staff: The information and suggestions from the medical staff were foundational to their decision-making. The caregivers needed the health care professionals' supports to deal with the concerns from patients and other family members as well as their emotional reactions.
