Psychological burden and depressive symptoms in caregivers of hemato-oncological patients: the role of medical visits

Abstract

Informal caregivers of patients with cancer are known to experience extensive burdens, whereas this issue remains unresolved in the setting of hematological malignancies. Yet, these diseases are characterized by a prolonged course, numerous relapses, and implementation of multiline therapy, administered in outpatient facilities. This study aimed to assess the factors contributing to burden and depressive symptoms in informal caregivers of patients with hematological malignancies, while concentrating on the role of medical visits. The study population comprised patients and their caregivers, recruited at the Rambam Hematology Ambulatory Unit. Participants completed validated questionnaires, including the Center for Epidemiologic Studies Depression Scale and the Zarit Caregiver Burden Interview. The cohort (n = 185) included 115 patients (average age, 62.8 ± 14.5 years; 54 males) and 70 caregivers. Among caregivers, 80% reported high psychological burden, and 50% reported significant depressive symptoms. The burden was higher if caregivers were females and if patients were less educated, less healthy, and more depressed. The caregiver burden and depressive symptoms were significantly linked, and the medical visit frequency predicted the level of both. The caregiver burden fully mediated the link between the independent variables of self-rated health and medical visits and the dependent variable of caregiver depressive symptoms. Informal caregivers of ambulatory patients with hemato-oncological malignancies experience high levels of psychological burden and depressive symptoms. This is partly attributed to the medical visit frequency. Hence, a decrease in the number and length of such visits via the implementation of advanced technology could essentially reduce burden and depressive symptoms of caregivers, without compromising patient outcomes.
