Household material hardships impact emergency department reliance in pediatric patients with sickle cell disease

Abstract

Background In sickle cell disease (SCD), high emergency department (ED) utilization is associated with worse outcomes and increased costs. A metric called ED reliance (EDr), the percentage of healthcare visits that occur in the ED, attempts to identify ED overutilization. It is unknown if household material hardships (HMH)—housing, utility, or food insecurity—impact reliance on the ED. As these may represent modifiable risk factors for high ED utilization, we aimed to estimate the association between HMH and EDr in pediatric patients with SCD. Methods We reviewed the electronic medical records of pediatric patients with SCD who received care in the Boston Medical Center network in Massachusetts, USA, to collect data on HMH and healthcare utilization. Using linear regression to control for potential confounders, we modeled the association between material hardships and EDr. Results Of 101 eligible patients, 60 (59%) reported one or more HMH. The mean EDr was 12% overall, with significant differences between those with and without HMH (15.9 vs 5.9, P = 0.0001). Each additional hardship experienced was associated with an increased average EDr of 7.7 percentage points (R ² = 0.34, P < 0.0001). Housing and utility hardships were each independently associated with increased EDr. Conclusion HMH are associated with significantly increased EDr in children with SCD, independent of transportation hardship or insurance type. Through screening for HMH, providers and health systems could identify at‐risk patients with modifiable risk factors for high EDr in order to provide them additional support.
