They conducted a pre- and post-intervention study of patients with suspected COVID-19 hospitalized at Massachusetts General Hospital (MGH) during March-July 2020. The Clinical Decision Support System (CDSS) was created: Calculator risk assessment (CORAL) using a modified Delphi method. CORAL was used in over 2000 consultations, and was used as a diagnostic algorithm and clinical scoring system to incorporate symptoms, epidemiological risk factors, and imaging findings to guide a suspected Covid patient after a test through diagnosis. initial negative. CORAL reduced the duration of isolation measures for suspected cases compared to individualized medical review, helping to preserve hospital capacity and improve patient care. The overall incidence of COVID-19 decreased before the implementation of CORAL, however, the difference in these results before and after CORAL was maintained when adjusting for the incidence of COVID-19.
