Risk score app accurately classifies COVID-19 outpatients who do not require testing or imaging

Clinical Question

Can a simple risk score tool accurately predict outpatients with COVID-19 who do not subsequently require any laboratory testing or imaging?

Bottom line

A simple risk score derived by the authors uses only age, dyspnea, and comorbidity to accurately identify more than 60% of patients with the Omicron variant of COVID-19 as being at low risk — and does so without the burden of additional testing. The LOCH risk score is available online as a free app. 1b

It would be helpful if the criteria for which patients with COVID who do not require testing or imaging were included in the INFOPoem.
