Background: Subcutaneous immunoglobulin (SCIG) is increasingly utilized in primary immunodeficiency (PI). Understanding factors associated with treatment experience and satisfaction can optimize patient outcomes. We analyzed Immune Deficiency Foundation (IDF) survey data to evaluate patient-reported outcomes (PROs) in relation to SCIG training and infusion characteristics. Respondents' PRO scores were rank ordered into 'best', 'intermediate', and 'worst' tertiles. Predicted probabilities of being in the best tertile with any combination of characteristics were generated for each PRO., Results: In 366 SCIG respondents, higher odds of being in the best PRO tertile were driven by favorable training characteristics (particularly, higher confidence post-training and no training barriers) and efficient infusions (infusion preparation ≤20 min and actual infusion < 2 h). Age (≤17 years old) and treatment experience (> 2 years) increased the odds of being in the best tertiles. Compared with the least favorable training/infusion characteristics, those with the most favorable training/infusion characteristics had higher predicted probabilities of being in the best tertiles: TSQM side effects, 59% vs 4%; convenience, 52% vs 4%; effectiveness, 27% vs 13%; global, 26% vs 3%; PROMIS Fatigue, 44% vs 18%., Conclusions: Increased experience with SCIG consistently improved PROs, but our findings predicted that enhanced training and infusion characteristics improve patient treatment satisfaction beyond that achieved by experience alone.

Objective: Caregivers for patients undergoing hematopoietic cell transplantation (HCT) are susceptible to significant psychosocial distress. This cross-sectional study aimed to describe psychosocial support services offered and used by caregivers of pediatric primary immune deficiency (PID) during HCT at 35 hospitals across North America., Method: Caregivers of pediatric patients with PID were recruited by e-mail to participate in an anonymous 140-question survey instrument between April and May 2016 (N = 171)., Result: Of those meeting inclusion criteria (53%), family counseling services were only offered to fewer than half of caregivers (42%). Of the survey participants not offered counseling services, the majority desired family counseling (70%) and sibling counseling (73%). That said, when offered counseling, utilization rates were low, with 22% of caregivers using family counseling and none using sibling counseling., Significance of Results: These results indicate the need to offer and tailor counseling services for families throughout the HCT process. Further research should focus on reducing barriers to utilization of counseling services such as offering bedside counseling services, online modalities, and/or financial assistance.

Background: Caregivers of children with primary immunodeficiency disorders (PIDs) experience significant psychological distress during their child's hematopoietic cell transplantation (HCT) process., Objectives: This study aims to understand caregiver challenges and identify areas for health care system-level improvements to enhance caregiver well-being., Methods: 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., Results: 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., Conclusions: 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., (Published by Elsevier Inc.)
