Improved Guideline Adherence With Integrated Sickle Cell Disease and Asthma Care

INTRODUCTION: In children with sickle cell disease (SCD), concomitant asthma is associated with increased morbidity and mortality when compared with children with SCD without asthma. Despite the well-established burden of asthma in children with SCD, no paradigm of care exists for the co-management of these two diseases. METHODS: To address this gap, an integrated SCD and asthma clinic was created in a community health center that included (1) a dual respiratory therapist/asthma case manager; (2) an SCD nurse practitioner with asthma educator certification; (3) an onsite pulmonary function test laboratory; (4) a pediatric hematologist with expertise in managing SCD and asthma; and (5) application of the National Asthma Education and Prevention Program guidelines. A before (2010–2012) and after (2013–2014) study design was used to assess for improved quality of care with implementation of an integrative care model among 61 children with SCD and asthma followed from 2010 to 2014. RESULTS: Asthma action plan utilization after initial diagnosis increased with the integrative care model (n=16, 56% before, 100% after, p=0.003), as did the use of spirometry in children aged ≥5 years (n=41, 65% before, 95% after, p<0.001) and correction of lower airway obstruction (n=10, 30% before, 80% after, p=0.03). CONCLUSIONS: Although the use of an integrative care model for SCD and asthma improved evidence-based asthma care, longer follow-up and evaluation will be needed to determine the impact on SCD-related morbidity.
