ObjectivesCaregiver burden often goes unrecognised and can substantially affect caregivers’ physical, psychological and financial well-being, thereby impacting quality of care. This study investigates burden among caregivers of children with chronic medical conditions in a tertiary care hospital in Pakistan. The study aims to assess the extent of burden, explore influencing factors and recommendations for interventions.DesignMixed-methods study, comprising of an in-person paper-based survey, employing the Zarit Burden Interview scale to assess burden scores. Qualitative component included thematic analysis of semi-structured in-depth interviews with caregivers.Participants383 caregivers of children admitted to the inpatient paediatric services at our tertiary care centre were surveyed. In-depth interviews were conducted with 19 caregivers.ResultsThe survey revealed a mean burden score of 35.35±15.14, with nearly half of the participants (46%, n=177) experiencing mild burden, while 37% (n=140) reporting moderate-to-severe burden. The most common diagnosis was cancer (24%, n=92), while the highest burden (42.97±15.47) was noted for congenital cardiac disease. Greater burden was significantly associated with lower caregiver education, young age of the child at diagnosis and increased number of hospital visits (p<0.05). Caregivers highlighted financial strain, psychosocial effects and impact on lifestyle and relationships as key challenges. They emphasised the need for improved medical coordination, financial support and enhanced hospital services.ConclusionsThe study elucidates the multifaceted nature of caregiver burden in the context of paediatric chronic illnesses in Pakistan. Interventions should emphasise financial aid, educational support and development of system-level changes to improve access to resources and medical care coordination. These insights call for policy and practice integration to support caregivers effectively.
