MDCalc

COVID-19 Inpatient Risk Calculator (CIRC)

Predicts likelihood of inpatient mortality or severe disease progression in COVID patients.

  • This calculator includes inputs based on race, which may or may not provide better estimates; this calculator cannot be run without the “White Yes/No” answer. Non-white patients tend to have higher mortalities in this score. See here for more on our approach to addressing race and bias on MDCalc.

Advice
  • This tool should not be used in isolation—clinical judgment remains essential.
  • Escalate care for high-risk patients (e.g., early ICU consult, closer monitoring) or consider de-escalation for low-risk patients when clinically appropriate.
  • Results can be used to guide goals of care discussions with patients and families.
