Popis: Introduction: Pediatric patients with sickle cell disease (SCD) experience considerable disease-related burden. SCD-related morbidity is characterized by vaso-occlusive crises (VOCs), which are acutely painful events that may cause chronic and potentially life-threatening complications, contributing to the early mortality associated with SCD. Two cross-sectional observational surveys were fielded to evaluate the relationship between VOC frequency and health-related quality of life (HRQoL) in pediatric patients with SCD in the United States (US). Methods: Surveys were administered in 2 populations: adolescents with SCD ages 12-17 years (n=247) and caregivers (n=167) of children with SCD ages 2 months-11 years in the US. Adolescent participants first provided assent to participate, and their guardians provided permission. Adolescents then completed an online survey that included the Child Health Questionnaire-Child Form 45 (CHQ-CF45) and the Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me) pain and sleep impact domains. After providing informed consent, caregivers completed an online survey assessing the HRQoL of their child with SCD; survey content was tailored to the age of their child. Caregivers of children ages 5-11 completed the CHQ-Parent Form 50 (CHQ-PF50) and the Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference and sleep disturbance short forms (8a and 4a, respectively). Caregivers of children Results: In adolescents ages 12-17, higher frequencies of VOCs were associated with lower HRQoL: adolescents with more frequent VOCs reported greater impacts than adolescents with less frequent VOCs across all domains of HRQoL measured by the CHQ-CF45, including general health, physical functioning, role/social limitations, mental health, and family activities (p Conclusions: Via both self- and caregiver-reports, these surveys demonstrated significant detrimental impact of VOCs on pediatric patients with SCD. Decrements were observed across various domains of HRQoL, including general health, physical functioning, pain, sleep, role/social limitations, and mental health. VOC frequency negatively impacted family activities and caregiver time and emotions, confirming anecdotal evidence that the effects of VOCs extend beyond the child to the caregiver. Given the cross-sectional study design, these analyses did not establish a temporal or causal relationship between VOCs and HRQoL; however, it is plausible that treatments aimed at reducing the frequency of VOCs may alleviate some of the burden experienced by pediatric patients with SCD and their families.
