Association between clinical outcomes and metformin use in adults with sickle cell disease and diabetes mellitus.
This study tested the hypothesis that metformin use for treatment of diabetes mellitus is associated with fewer sickle cell disease (SCD) adverse outcomes and lower health care utilization among patients with SCD and diabetes mellitus. This retrospective cohort study used data from MarketScan Medicaid claims for 2006 to 2016. SCD patients who were metformin users and nonusers were compared. Patients on hydroxyurea, insulin, or iron chelation were excluded. Metformin was found to be associated with significantly fewer inpatient and emergency department encounters in adults with SCD and diabetes mellitus.

Transition to adult care in sickle cell disease: a longitudinal study of clinical characteristics and disease severity.
Researchers conducted a longitudinal analysis of medical records of adolescents and young adults (AYAs) with sickle cell disease (SCD) to describe the clinical course among AYAs during transition to adult care. They found that, whereas most AYAs had stable severity, nearly a quarter had increasing severity over time. AYAs with increasing severity had more complications, were more likely to transfer to adult care, and demonstrated higher and longer adult SCD care utilization compared with AYAs with stable severity.

Development of a hydroxyurea decision aid for parents of children with sickle cell anemia.
This study developed a decision aid for use of hydroxyurea for parents of children with sickle cell anemia. There are national evidence-based guidelines, but they do not offer strategies for implementation. A multicomponent decision aid was developed via a needs assessment, clinic observations and iterative feedback. The decision aid was considered useful by the 75 parents and 28 clinicians who participated in all phases of the study.

Exploring emergency department provider experiences with and perceptions of weight-based versus individualized vaso-occlusive treatment protocols in sickle cell disease.
This study compared perceptions of nurses and physicians on protocols to treat sickle cell disease vaso-occlusive episodes (VOEs) in emergency rooms (ERs). Two different protocols were used for VOEs: weight –based and individualized vaso-occlusive. Nurses were less satisfied with clarity of the protocols than physicians. Pain management protocol perceptions differed widely between physicians, residents, physician assistants, nurse practitioners and nurses.

Attitudes toward patients with sickle cell disease in a multicenter sample of emergency department providers.
The authors aimed to validate a survey that measures attitudes toward sickle cell disease (SCD) patients among emergency department (ED) providers and to compare differences in attitude scores between provider types. They found that, among ED providers, this scale identified a dimension not observed in research with the original instrument among internal medicine providers. They concluded that provider attitudes influence patient-provider interactions and quality of care.

Identifying sickle cell disease cases using administrative claims.
The authors developed and tested the accuracy of administrative claims method for identifying children with sickle cell disease (SCD) to enable quality of care assessments among children enrolled in Medicaid. They found that their definition can be used to facilitate a more accurate identification of children with SCD in future studies.
