Background: An increasing number of patients with terminal illnesses prefer to die in their own homes due to aging, high medical payments, a limited number of hospitalization days, and the ability to receive care from family members. However, few studies have been conducted on the subjective perception and value of caregivers for home-based palliative care (HBPC).; Objective: To identify common themes and topics of primary family caregivers' lived experiences with HBPC when taking care of terminally ill family members.; Methods: We conducted audio-recorded transcripts of one-on-one in-depth interviews of primary family caregivers of HBPC. Through a purposive sampling method, the participants were all interviewed; these interviews were transcribed verbatim and analyzed using a grounded theory approach.; Results: A total of 22 primary family caregivers participated in the study. "Wholeheartedly accompanying one's family to the end of life at home" was the core category. Six main themes describing caregivers' experiences emerged from the interviews: (1) learning the basic skills of end-of-life home care, (2) arranging the sharing and rotation of care, (3) preparing for upcoming deaths and funerals, (4) negotiating the cultural and ethical issues of end-of-life home care, (5) ensuring a comfortable life with basic life support, and (6) maintaining care characterized by concern, perseverance, and patience.; Conclusions: Primary family caregivers of HBPC need support and must learn home care skills by means of the holistic approach. It is crucial to establish assessment tools for caregivers' preparedness for HBPC, including biopsychosocial and cultural considerations .
