| Popis: | Abstract 2106 Introduction: Over the past few decades, lifespans of sickle cell disease (SCD) patients have increased; hence, they encounter multiple complications. Early detection, appropriate comprehensive care, and treatment may prevent or delay onset of complications. There is a gap in the literature describing the SCD complication rates, blood transfusion patterns, iron chelation therapy (ICT) use, and associated resource utilization in SCD patients ≥16 years old. This study contributes to addressing this gap. Method: Medical records of 254 SCD patients ≥ 16 were retrospectively reviewed between August 2011 and July 2012 at three US tertiary care centers (University of Tennessee: 117; Tulane University: 72; Howard University: 65). Data were collected from patient's first visit after age 16 (index date) until the earliest indication of death, loss to follow-up, or last patient record on file prior to the centers' IRB submission dates. Patients were classified into one of three cohorts based on cumulative units of blood transfused and history of ICT: Results: Cohorts 1, 2, and 3 consisted of 69, 91, and 94 patients, respectively. Mean (range) age at index date was similar across cohorts (27 yrs [16–65]) and all patients were African American. Mean length of observation was shorter among patients in C1 (yrs, C1: 6.6; C2: 8.2; C3: 8.1). Post index date, patients in C1 received an average of 1 unit of blood PPPY (p Conclusion: Results from this study highlight the significant burden of complications and the associated healthcare resource utilization for SCD patients. The results suggest that among regularly transfused patients, those who received ICT were less likely to experience complications than those without ICT. However, transfusions are not necessary for all patients with SCD and patients with more complications may have started transfusion therapy earlier. Patients receiving ICT may also receive closer monitoring, which may help with early identification and intervention to delay or prevent the development of complications and improve outcomes.
