Knowledge Accuracy Among Adolescents with SCD
Seventeen items in 6 PHR domains had the highest number of data points (at least 75% verified), and therefore were the only items that could be analyzed. Analyzed items included information about sickle cell genotype, eye doctor care, comorbid health issues (eg, asthma), allergies, hospitalizations, surgeries, transfusions, acute chest syndrome (ACS) episodes, eye problems, baseline hemoglobin level, and vaccination history as well as adolescents’ knowledge of current medications, including hydroxyurea, penicillin, and opioid pain medications.
Gender was not significantly associated with overall accuracy (P = 0.36). A significant difference was found in sickle genotype such that individuals with HbSC/Sβ+ thalassemia genotype (mean number of items, 8.23; SD = 1.70) were more accurate reporters of their medical history than those with HbSS/Sβ0 thalassemia genotype (mean number of items, 7.14; SD = 1.75; t(65) = –2.59, P = 0.01). Specifically, those with HbSS/Sβ0 thalassemia genotype were significantly less accurate reporters of vaccination history (meningococcus t(60) = 3.55, P = 0.001; pneumococcus t(60) = 2.46, P = 0.02; hepatitis t(64) = 2.18, P = 0.03, eye problems t(62) = 3.62; P = 0.001, and surgical history t(62) = 2.14, P = 0.04).
