Comparison of Covid SeveriTy score PReDiCTOR 50 and CURB 65 in prognostic assessment of patients with COVID 19 illness

ABSTRACT

Background: The greatest difficulty during the COVID pandemic was in effective triaging of patients. A new scoring system was developed by our center in order to provide a holistic assessment of the illness including systemic manifestations. This study was to evaluate the effectiveness of the scoring system in comparison to CURB 65, the most commonly used screening tool for prognostic assessment of pneumonia. Aim: To compare CURB 65 and Covid Severity Score Predictor 50 in measuring prognosis in patients with COVID 19 illness Methods: 150 Patients with COVID 19 illness were enrolled . The COVID severity score PReDiCTOR 50 was designed in our set up during the pandemic to assess prognosis of disease. This is retrospective analysis to compare the efficacy of the predictor against CURB 65 in assessing prognosis of COVID 19 illness using receiver operator characteristic curves and associated area under the curve. \ Results: We studied 150 patients with COVID 19 illness. 35 died and 103 were discharged. The ability to predict ICU admission was higher for our scoring system (AUC 0.875 ) as compared to CURB 65 ( AUC 0.83). Conclusion: The Covid SeveriTy Score PReDiCTOR 50 was found to be more effective in prognostic assessment of COVID 19 illness in comparison to CURB 65, indicating the importance of holistic assessment of COVID.
