4Ever hospitalized, if available, as reported to OPERA. OPERA is the state of Oregon’s electronic disease surveillance system for COVID-19. Cases are considered hospitalized if they were ever admitted to the hospital for inpatient care during the their COVID-19 illness. Cases who were examined in but not admitted to a hospital may be incorrectly classified as hospitalized until interview and medical record review are complete, leading to fluctuations in the number of hospitalized COVID-19 cases.

5As reported to Oregon’s Hospital Capacity Web System (HOSCAP). Every hospital in Oregon is asked to submit data twice daily HOSCAP. Hospital staff are asked to enter bed capacity information, by type, as well as the numbers of patients with suspected or confirmed COVID-19 illness who are currently hospitalized at the time of data entry. These data may conflict with hospitalization status in OPERA due to case reporting and investigation lags and temporary discrepancies in case classification.
