The Africa Federation of Emergency Medicine has developed a screening tool for the severity of COVID-19. This tool is both paper-based and online. For the latter, AFEM partnered with Surgisphere to develop an online COVID-19 Severity Scoring Tool. They used advanced machine learning on hospital-based data from 13,500 COVID-19 patients.
The tool aims to aid frontline providers in rapidly determining which patients presenting to Emergency Units with suspected or confirmed COVID-19 require respiratory interventions.
The tool assigns patients into a severity category that aligns to WHO's classification: critical, severe and moderate/mild.
Critical patients require ventilation;
Severe patients require oxygen;
Moderate patients have pneumonia but no oxygen need;
Mild patients only have upper respiratory tract disease.
This tool will make one of three recommendations:
Critical status: consider ICU and/or mechanical ventilation;
Severe status: consider oxygen and supportive care;
Moderate or mild status: limited supportive care may be needed.
An early assessment suggests that the tool correctly classifies 93.6% of patients, overestimating 5.7% and underestimating 0.8% of patient severities.
Additonal ICU admission criteria include:
Clinical Fraility Score
SOFA Score (Sequential Organ Dysfunction Score)
