Background: A major limitation of predictive prognostic models in COVID-19 patients is the heterogeneity of disease stage and population. This study aims at identifying a panel of clinical and laboratory parameters that at day-5 of symptoms onset could predict disease progression within 11 days in hospitalized COVID-19 patients. Methods: Single-centre, prospective cohort study on hospitalized adult COVID-19 patients. Patient-level epidemiological, clinical, and laboratory data were collected at fixed time-points: day-5, -10, and -15 from symptoms onset and in case of intensive care unit (ICU) admission, discharge, or death. COVID-19 progression was defined as in-hospital death and/or ICU and/or respiratory failure (PaO2/FiO2 ratio65 years, cardiovascular disease, and at least three abnormal laboratory parameters among CRP > 80 U/L, AST > 45 U/L, ALT > 40 U/L, NLR > 4·5, LDH > 250 U/L, and CK > 80 U/L showed an AUC of 0·73 (95%CI: 0·66 - 0·81) for predicting disease progression. Conclusion: An easy-to-use panel of laboratory/clinical parameters computed at day-5 from symptoms onset predicts, with fair discrimination ability, COVID-19 progression. Assessment of these features at day-5 from symptoms onset could facilitate clinicians’ decision making and be used to increase patient population in clinical trials in hospitalized patients.
