Hospital impact is based on a composite score of four measures: 1.% of hospitalizations from COVID-19; 2. COVID-19 related visits to the hospital emergency department; 3. Total number of open beds for which the hospital has people to staff; and, 4. critical staffing shortages.
Counties without a hospital are assigned the average hospital impact score from the county where the highest percentage of their inpatient hospital admissions occurred.
To be assigned to the red or orange tier, a county must meet the threshold for case rate for that tier and the threshold for either% positive or hospital impact.
For red, the thresholds are more than 200 new cases in the prior two weeks, more than 10% positive and high impact on county hospital.
For orange, the thresholds are 101-200 new cases in the prior two weeks, 8-10% positive and moderate impact on county hospital.
