Primary caregivers face constant challenges because of changes in the clinical situation of the person receiving palliative home care. These changes can alter the health-related quality of life and all its dimensions. This study aimed to describe the health-related quality of life of 137 primary caregivers of people enrolled in a palliative home care program in Bogotá, Colombia, applying a quantitative, descriptive, and cross-sectional research design. The Caregiver's Quality of Life Instrument, initially developed by Ferrell, and the sociodemographic characteristics form for caregivers of people with chronic disease, both previously validated in the Colombian population, were used. The results showed that the primary caregivers have a good and adequate overall health-related quality of life; however, they presented some alterations in the physical, psychological, and social dimensions. Therefore, nursing and interdisciplinary palliative care teams should aim their interventions not only at patients but also at primary caregivers during palliative home care.
