Prevalence and factors associated with caregiver burden in palliative care in Phra Nakhon Si Ayutthaya Hospital: a cross-sectional study

Background: Caregiver burden significantly impacts the physical health and quality of life (QoL) of those looking after palliative care patients. Identifying the prevalence and specific determinants of this burden is crucial for developing effective supportive interventions. Objective of the study was to determine the prevalence of caregiver burden and identify factors associated with higher burden levels among primary caregivers of palliative care patients. Methods: This cross-sectional study was conducted among 190 caregivers at Phra Nakhon Si Ayutthaya Hospital. Data were collected using a two-part structured questionnaire: socio-demographic characteristics of caregivers and patients, and the Thai version of the Zarit burden interview (ZBI) to assess caregiving burden. Participants were categorized into "no-to-mild burden" and "moderate-to-severe burden" groups for comparative analysis. Results: Of the 190 participants (46 males, 144 females), the prevalence of no-to-mild burden was 86.84%, while 13.16% experienced moderate burden; notably, no cases of severe burden were reported. Statistical analysis revealed that factors significantly associated with increased caregiver burden (p16 hours/day) and those caring for younger or highly educated patients. Implementing support systems, such as caregiver rotation and tailored communication strategies regarding disease progression, is essential to mitigate anxiety and optimize palliative care outcomes.
