Caregivers of children with primary immunodeficiency disorders (PIDs) experience significant psychological distress during their child's hematopoietic cell transplantation (HCT) process.

This study aims to understand caregiver challenges and identify areas for health care system-level improvements to enhance caregiver well-being.

In this mixed-methods study caregivers of children with PIDs were contacted in August to November 2017 through online and electronic mailing lists of rare disease consortiums and foundations. Caregivers were invited to participate in an online survey assessing sociodemographic variables, the child's medical characteristics, psychosocial support use, and the World Health Organization–5 Well-Being Index. Open-ended questions about health care system improvements were included. Descriptive statistics and linear multivariate regression analyses were conducted. A modified content analysis method was used to code responses and identify emergent themes.

Among the 80 caregiver respondents, caregivers had a median age of 34 years (range, 23-62 years) and were predominantly female, white, and married with male children given a diagnosis of severe combined immune deficiency. In the adjusted regression model lower caregiver well-being was significantly associated with lower household income and medical complications. Challenges during HCT include maintaining relationships with partners and the child's healthy sibling or siblings, managing self-care, and coping with feelings of uncertainty. Caregivers suggested several organizational-level solutions to enhance psychosocial support, including respite services, online connections to other PID caregivers, and bedside mental health services.

Certain high-risk subpopulations of caregivers might need more targeted psychosocial support to reduce the long-term effect of the HCT experience on their well-being. Caregivers suggested several organizational-level solutions for provision of this support.
