Background: In children with sickle cell disease (SCD), comorbid asthma is associated with increased disease severity and morbidity, but it remains underdiagnosed and optimal management paradigms are not well defined. The purpose of this study was to determine the feasibility and preliminary outcomes of an integrated pediatric SCD and pulmonary care clinic in children with SCD., Methods: We implemented a pre-post quality improvement (QI) project in our pediatric hematology clinic between 2017 and 2019. Guided by the chronic care model, patients who were ages 2-18 years, diagnosed with SCD and suspected pulmonary comorbidities, received care in an interdisciplinary clinic. We examined feasibility and compared clinical outcomes to 24 months prior (2015-2017) to the implementation of the integrated care model., Results: Twenty-four patients were included in the QI project: 88% (n = 21) received pulmonary function testing, 92% (n = 22) were diagnosed with asthma, and 33% (n = 8) with obstructive sleep apnea. Adherence to pulmonary appointments was increased by 81% (mean difference [MD] = 1.3, 95% confidence interval [CI] = 0.71-1.92; P < .001). Unplanned acute health care utilization was reduced by 59% (MD = 2.9, 95% CI = 1.14-4.69; P < .01) and packed red blood cell transfusion was reduced by 81% (MD = 1.38, 95% CI = 0.71-2.04; P < .001)., Conclusion: Asthma is prevalent in children with SCD, and interdisciplinary clinics can improve access to subspecialty pulmonary care and reduce unplanned acute care. Additional patients and a longer follow-up period are required to determine the true treatment effect., (© 2020 Wiley Periodicals LLC.)
