A clinical evaluation program to monitor neurocognitive risk in children and adolescents with sickle cell disease.

Sickle cell disease (SCD) is an inherited hematologic disorder that impacts approximately 100,000 Americans. This disease is associated with progressive organ damage, cerebral vascular accident, and neurocognitive deficits. Recent guidelines from the American Society of Hematology (ASH) recommend cognitive screening with a psychologist to help manage cerebrovascular risk and cognitive impairment in this population. SCD patients benefit from neuropsychology services and several institutions already have programs in place to monitor cognitive risk. We describe a longitudinal neurocognitive evaluation program at our institution that serves all patients with SCD, regardless of disease severity or referral question. The Sickle Cell Assessment of Neurocognitive Skills (SCANS) program was established in 2012. We outline the program's theoretical framework, timepoints for evaluation, test battery, logistics, patient demographics, integration with research programming, and multidisciplinary collaboration to support optimal outcomes. Our program has provided 716 targeted neuropsychological evaluations for patients over the last decade. Nearly 26% of patients in the program have been followed longitudinally. The most common diagnoses generated across cross-sectional and longitudinal evaluations include cognitive disorder ( = 191), attention-deficit/hyperactivity disorder ( = 75), and specific learning disorder ( = 75). Approximately 87% of patients who participated in SCANS during late adolescence successfully transitioned from pediatric to adult care. We discuss considerations for developing programming to meet the needs of this population, including tiered assessment models, timing of evaluations, scope, and reimbursement. Program models that utilize prevention-based tiered models or targeted evaluations can assist with serving large volumes of patients.
