Figure 2. Association Between Medical Complexity and Risk of Hospitalization or Severe Illness When Hospitalized in the Sample.

Figure 2.

Medical complexity was defined by the Pediatric Medical Complexity Algorithm. The sample was defined as children aged 18 years or younger with a COVID-19 diagnosis during an emergency department or inpatient encounter in hospitals that reported both emergency department and inpatient encounters to Premier Healthcare Database Special COVID-19 Release, March 2020 through January 2021. Each panel represents results of a single generalized linear model with Poisson distribution and log link function, that includes the following covariates: medical complexity (presence of noncomplex chronic disease, presence of complex chronic disease, and no chronic disease as reference group), age group, sex, race/ethnicity, payer type, hospital urbanicity, hospital US Census region, admission month, and admission month squared.
