To develop a prognostic model to identify and quantify risk factors for mortality among patients admitted to the hospital with COVID-19.Design
Retrospective cohort study. Patients were randomly assigned to either training (80%) or test (20%) sets. The training set was used to fit a multivariable logistic regression. Predictors were ranked using variable importance metrics. Models were assessed by C-indices, Brier scores and calibration plots in the test set.Setting
Optum de-identified COVID-19 Electronic Health Record dataset including over 700 hospitals and 7000 clinics in the USA.Participants
17 086 patients hospitalised with COVID-19 between 20 February 2020 and 5 June 2020.Main outcome measure
