Factors associated with high care burden of primary caregivers of children with medical complexity after completing a discharge-support program in a recovery center

Recently, many seriously ill children requiring medical equipment are being recommended to transition from hospital to home care in Japan. Since 2011, our recovery center has provided a support program for the transfer process from hospital to home for ill children and their families. The purpose of this study was to evaluate the factors related to high care burden after completing the discharge-support program. A questionnaire-based cross-sectional study was conducted on all primary caregivers whose children received the program in our center and moved from hospital to home (30 children and 29 families) from May 2011 to May 2018. Fifteen children came from the neonatal intensive care unit. The questionnaire consisted of three parts: characteristics of children and families and life after the program; the Zarit Burden Interview (ZBI); and the Positive and Negative Affect Schedule (PANAS). Twenty-three primary caregivers responded (79% response rate). All children received tracheostomy and 71% received home mechanical ventilation. Primary caregivers were all mothers. High ZBI score was not related to the severity and type of medical equipment. There were relationships between high ZBI score and following factors: ‘unimproved relationship between patients and family members without primary caregivers’ and ‘additional medical equipment after discharge’. The result of PANAS showed that positive attitude was not different between those with high and low ZBI scores. It is crucial to reach out to family members without a primary caregiver. Additional medical care/equipment after the program is related to the care burden of primary caregivers.
