Healthcare Utilization Among Children and Adolescents with Sickle Cell Disease during the COVID-19 Pandemic

Background Early experience with the COVID-19 pandemic showed disproportionately high morbidity and mortality among individuals with certain chronic medical conditions. Individuals with sickle cell disease (SCD) are at high risk for pulmonary and other complications including acute chest syndrome (ACS) and have high rates of hospitalization from other viral respiratory infections, raising concern that COVID-19 would be associated with higher morbidity, mortality and health care utilization among those with SCD. Public health interventions such as social distancing, avoidance of large group activities, and widespread use of masks have been shown to reduce the transmission of COVID-19 in the general population but have been inconsistently implemented. In Georgia, COVID-19 restrictions, including school closures, were implemented in mid-March, and on-site school instruction was replaced by virtual instruction for the remainder of the school year. At our institution, most routine, non-urgent outpatient clinic visits were cancelled or postponed from mid-March through May in order to minimize COVID-19 exposure risk. Efforts to initiate the use of telemedicine as an alternative to in-person office visits were rapidly instituted. We hypothesized that adherence to public health restrictions, especially sheltering in place, would be high among patients and families with SCD, and sought to measure the impact of COVID pandemic on healthcare utilization in children and adolescents with SCD in the Atlanta area. Methods The SCD Program at Children's Healthcare of Atlanta (CHOA) provides comprehensive outpatient, emergency and inpatient services at 3 locations in metropolitan Atlanta. CHOA's Sickle Cell Clinical Database (SCCD) contains prospectively collected demographic, diagnostic, treatment and other clinical information on all patients with SCD beginning in 2010, including all outpatient clinic, emergency department (ED) and inpatient hospital utilization. To assess the impact of COVID-19 on healthcare utilization, we tracked clinic, ED and inpatient utilization for the 4-month period (March through June) 2020 compared with the same 4-month period in 2018 and 2019. Results The figure shows utilization patterns for each four-month period from 2018-2020. As expected, face to face outpatient clinic visits fell dramatically from February to April 2020 (-25% in March, -64% in April) and then returned to pre-COVID levels by June. The addition of telemedicine visits raised
