Deriving a patient de-identified clinical research database from an electronic health record system: A single center experience in determining the prognostic value of lactate, C-reactive protein, and procalcitonin in hospitalized patients

Objective: In this study, we demonstrate the derivation of a de-identified research database from the electronic health records (EHR) and then use it in determining the prognostic value of biomarkers lactate, C-reactive protein (CRP), and procalcitonin in hospitalized patients.
