Economic burden and quality of life of caregivers of patients with sickle cell disease in the United Kingdom and France: a cross-sectional study

BackgroundSickle cell disease (SCD), a genetic blood disorder that affects red blood cells and oxygen delivery to body tissues, is characterized by haemolytic anaemia, pain episodes, fatigue, and end-organ damage with acute and chronic dimensions. Caring for patients with SCD imposes a high burden on informal caregivers. This study aims to capture the impact on health-related quality of life (HRQoL) and economic burden of caregiving for patients with SCD.MethodsValidated instruments of HRQoL (EQ-5D-5L, Carer Quality of Life-7 dimensions [CarerQol-7D]) and productivity (Work Productivity and Activity Impairment Questionnaire: Specific Health Problem [WPAI: SHP]) were administered via a cross-sectional online survey to caregivers in the United Kingdom (UK) and France. Demographics, HRQoL, and economic burden data were analyzed using descriptive statistics. Economic burden was determined using country-specific minimum and average wage values. Subgroup analysis examined caregivers with and without SCD.ResultsSixty-nine caregivers were recruited (UK, 43; France, 26), 83% were female, and 22% had SCD themselves. The mean (SD) caregiver EQ-5D-5L score was 0.66 (0.28) (UK, 0.62; France, 0.73), and the mean CarerQol-7D score was 80.69 (24.40) (UK, 78.72 [25.79]; France, 83.97 [22.01]). Mental health problems were reported in 72% and 70% of caregivers measured using the EQ-5D-5L and CarerQol-7D, respectively. Financial problems were reported by 68% of caregivers, with mean annual minimum wage productivity losses of 4209 pound and <euro>3485, increasing to 5391 pound and <euro>9319 for average wages. Sensitivity analysis determined additional HRQoL decrements for caregivers with and without, SCD.ConclusionCaring for patients with SCD impacts the HRQoL and economic burden of caregivers. Further research to support the complex needs of SCD caregivers is required. Caregivers play an important role in the lives of the people with sickle cell disease that they care for; however, their mental and physical health and their finances can be affected, particularly if their ability to work is impacted. The extent to which caring for a person with sickle cell disease impacts caregivers is not fully understood. In this study, 69 caregivers of a family member, partner, or friend with sickle cell disease in the United Kingdom or France completed an online survey to share their experiences about how caring for someone with sickle cell disease can impact a caregiver's quality of life and financial well-being. Caregiving negatively affected the quality of life of caregivers compared with people in the general population and caused a large financial and social burden. Around 70% of caregivers reported having mental health problems, 68% reported financial problems, and lost work hours and lost income were not uncommon. More research is needed to understand the specific needs of caregivers of people with sickle cell disease and how best to support them.
