Setting
CHCO is a regional, academic quaternary-care pediatric hospital with affiliated sites serving children in the Denver metropolitan area, the greater Colorado area, and the seven surrounding states. The main hospital campuses in Aurora and Colorado Springs, in conjunction with six satellite locations, have 560 beds and admits over 15,000 inpatients per year. The Center for Cancer and Blood Disorders (CCBD) provides clinical services for children, adolescents, and young adults with cancer and non-malignant blood disorders at Children’s Hospital Colorado and Network of Care locations. Study investigators extracted data from the electronic health record via systematic, concurrent and retrospective chart review. Approval was obtained from the Colorado Multiple Institutional Review Board (COMIRB # 20-1578).
