Outcomes before and after providing interdisciplinary hematology and pulmonary care for children with sickle cell disease

People with sickle cell disease (pwSCD) are at risk of developing lung conditions that complicate their SCD but often face health care access barriers. An interdisciplinary clinic providing pulmonary care for pwSCD was created in 2014 at the Nationwide Children's Hospital (NCH) to address access barriers that may prevent optimized treatment. We hypothesize that pwSCD and pulmonary disease would have fewer hospitalizations for acute chest syndrome (ACS), asthma, and vaso-occlusive episodes in the 2 years after their initial SCD-pulmonary clinic visit compared with the 2 years before. From 2014 to 2020, 119 pwSCD were evaluated in the SCD-pulmonary clinic and followed up at the NCH for at least 2 years before and after this initial visit. Acute care outcomes, pulmonary function, polysomnography, echocardiogram, laboratory, and medication prescribing data were collected and analyzed using the Wilcoxon signed ranked and McNemar tests. The median number of acute care visits for ACS (P < .001) and asthma (P = .006) were significantly lower during the 2 years after pwSCD's initial SCD-pulmonary clinic evaluation compared with the 2 years before. Asthma and allergic rhinitis were more frequently diagnosed and prescriptions for hydroxyurea (P = .005) and inhaled corticosteroids (P = .005) were more common in the post-SCD-pulmonary clinic period. The median number of prescribed systemic corticosteroids was lower in the 2 years after SCD-pulmonary clinic evaluation (P < .0001). Lactate dehydrogenase and white blood cell counts also significantly decreased. Implementing a multidisciplinary SCD-pulmonary clinic is feasible and may allow improved management of pulmonary problems and lead to improvements in the usage of health and acute care.

Automated summary

An interdisciplinary clinic providing pulmonary care for people with sickle cell disease (pwSCD) was created in 2014 to address health care access barriers. The study found that pwSCD had significantly fewer hospitalizations for acute chest syndrome, asthma, and vaso-occlusive episodes in the 2 years after their initial SCD-pulmonary clinic visit compared with the 2 years before. This suggests that implementing a multidisciplinary SCD-pulmonary clinic can improve patient management and usage of acute care.
