OBJECTIVES: Investigate factors associated with health-related quality of life (HRQoL) and economic burden in persons with sickle cell disease (SCD). Here we present HRQoL data. METHODS: Between July 2019 and August 2020, we recruited 32 adults aged ≥18 years with a diagnosis of SCD. We collected data on patient socio-demographics, fatigue, and HRQoL measured by the EQ-5D-3L and Adult Sickle Cell Quality of Life Measurement Information System (ASCQ-Me) via patient survey. Number of hospitalizations from the prior 12 months was obtained from chart review. Factors associated with HRQoL scores were assessed by Pearson correlation. RESULTS: Mean age was 36.7±10.6 (standard deviation) years, 65.6% of the sample was female, 84.4% had identified hemoglobin (Hb)SS/Sßthal0 disease, 81.3% reported chronic pain (experiencing pain on ≥3 days per week in the past 6 months). Mean EQ-5D VAS was 63.4, lower than the U.S. 35-44 age mean of 81.8. Mean EQ-5D index score was 0.79, lower than the U.S. 35-44 age group population norm (0.85). ASCQ-Me scores are comparable to the referent population of adults with SCD. Mean fatigue score was 57.9, ranged 33.7-75.9, and was negatively correlated with the EQ-5D index score (correlation coefficient r=-0.35, p=0.049), and ASCQ-Me scores, including pain (r=-0.47, p=0.006), sleep (r=-0.38, p=0.03), and emotion (r=-0.79, p<0.0001). Medical history checklist (MHC) score (sums 9 SCD complications and treatment history) was negatively correlated with EQ-VAS (r=-0.53, p=0.002), EQ-index score (r=-0.50, p=0.004), ASCQ-Me pain (r=-0.41, p=0.02), and stiffness (r=-0.63, p=0.0001). Number of hospitalizations was negatively correlated with HRQoL (all p<0.05). Patients who reported chronic pain had significantly lower mean ASCQ-Me sleep score (48.3±10.1 vs. 57.1±9.1, p=0.04) and EQ-5D index score (0.72±0.21 vs. 0.89±0.09, p=0.002) than those without chronic pain. CONCLUSIONS: Fatigue, MHC, hospitalization and chronic pain negatively impact HRQoL. Next steps are to evaluate the economic burden of illness on people with SCD.
