Family bonds and personal factors in caregiver burden in patients at the end of life.

Abstract

Family caregivers are defined as those who assume substantial responsibilities for the care of an ill loved one without formal health care training. This study aims to analyze the predictors of physical and emotional burden in caregivers of palliative patients using qualitative comparative analysis methodologies (QCA) and taking into account patient and caregiver personal and relational variables. A total of 125 caregivers of patients at the end of life were assessed using an ad hoc emotional and physical burden questionnaire and patient and caregiver personal and relational variables were recorded. Results indicate moderately high levels of both emotional and physical burden. Differences in burden are found only as a function of kinship. Emotional burden is positively associated with the use of physical health medication in the caregiver and kinship; meanwhile, physical burden is positively associated with time since diagnosis, patient functional independence, and economic problems. For the QCA models, several pathways predict the observed variance in the emotional and physical burden of family caregivers of patients at the end of life, based on patient, caregiver, and relationship variables. In conclusion, it is relevant to design intervention programs focused on patient-caregiver relationship to prevent the development of emotional and physical burden.
