Advice

  • Threshold for disposition may change during resource-limited situations such as the current COVID-19 outbreak. 

  • Take into consideration that the upper limit of the “low risk” group as indicated in the original study still carries a relatively high mortality rate (e.g. 11 points = 12.27% mortality).

Critical Actions

If applying to a patient with potential COVID-19, use this score in conjunction with clinical suspicion and risk factors - particularly advanced age and comorbidities.
