Adults with sickle cell disease (SCD) in the United States (22 studies).
Two systematic literature reviews to estimate the patient-reported outcomes and economic burden of SCD.
The prevalence of depression and anxiety was 21-33% and 7-36%, respectively. Overall health-related quality of life for adults with SCD was poor and significantly worse in those with opioid use. Adult SCD patients were found to have varying rates of emergency department (ED) utilization (0.3-3.5 annual ED visits), hospitalizations (0.5-27.9 per patient per year), and/or readmission (12-41%). Key factors associated with significant healthcare resource utilization were age, dental infection, and SCD-related complications. SCD specialized care settings and SCD intensive management strategy were reported to significantly decrease the number of hospitalizations.
