ABSTRACT
OBJECTIVES: Sickle cell disease (SCD) is characterized by a mutation in the beta-globin gene resulting in abnormal hemoglobin S (HgbS). The significant sequela of SCD include anemia and recurrent vaso-occlusive episodes (VOEs) which may effectuate patients to receive chronic blood transfusions. Current pharmacotherapy options for SCD include hydroxyurea, voxelotor, Lglutamine, and crizanlizumab. Simple and exchange transfusions are often utilized as prophylaxis to prevent emergency department (ED)/urgent care (UC) visits or hospitalizations from VOEs by reducing the level of sickled red blood cells (RBCs). In addition, the treatment of VOEs involves intravenous (IV) hydration and pain management. Studies have demonstrated that sickle cell infusion centers (SCIC) decrease hospital admissions for VOEs, and IV hydration and pain medications are the key components of management employed. Thus, we hypothesized that implementing a structured infusion protocol in the outpatient setting would reduce the incidence of VOEs. METHODS: Here, we discuss two patients with SCD who were trialed on scheduled outpatient IV hydration and opioids with the goal of decreasing the frequency of VOEs in the setting of the current blood product shortage and the patients' refusal to receive exchange transfusions. RESULTS: Overall, the two patients had opposing outcomes- one demonstrated reduced frequency of VOEs, whereas the other had mixed results due to noncompliance to scheduled outpatient sessions. DISCUSSION/CONCLUSION: The use of outpatient SCICs may be an effective intervention for prevention of VOEs in patients with SCD, and further patient-centered research and quality improvement initiatives are needed to further quantify and understand the factors contributing to their efficacy.
