Summary: | Background
Patients with sickle cell disease (SCD) may require chronic transfusion therapy (CTT) for prevention of stroke or other complications. Limited health literacy (HL) is common and is associated with poor health‐related knowledge and outcomes in chronic disease. We sought to assess HL and transfusion knowledge in patients with SCD on CTT and their caregivers.
Methods
A cross‐sectional study of patients was conducted in outpatient hematology clinics. Forty‐five pairs of adolescent patients and caregivers and 20 caregivers of pre‐adolescent patients completed the Newest Vital Sign HL assessment and answered questions assessing SCD and transfusion knowledge. Community‐level median income and unemployment rates were estimated from Census data. We computed the correlation of HL with knowledge and compared each to Census variables, payor status, educational attainment, and stroke.
Results
HL was inadequate in 22 (34%) caregivers and 31 (69%) adolescents. Adequate caregiver HL was associated with higher educational attainment but not community‐level socioeconomics or payor status. Mean knowledge score was lower in adolescents than in caregivers and correlated with age in adolescents (r = 0.42, P = .004). HL correlated with knowledge (r = 0.46, P < .0001). There were no significant correlations of HL or knowledge between adolescents and their caregivers. Neither HL nor knowledge was associated with prior stroke. The greatest knowledge was demonstrated for iron overload and SCD genotype, whereas knowledge gaps existed in alloimmunization, indication for CTT, and SCD curative therapy.
Conclusions
Enhanced educational resources in transfusion therapy, alloimmunization, and curative therapy are needed for patients with SCD and caregivers of all HL levels. |
