“Welcome to COVID-19 Data Discovery from Clinical Records – your resource for questions and answers about COVID-19, funded by the Gordon and Betty Moore Foundation. We use electronic health record (EHR) data from 12 leading medical centers to answer simple and complex clinical questions related to COVID-19. Because we consult multiple centers, we have a relatively large number of COVID-19 cases to discover patterns while maintaining patient and institutional privacy. In this project, EHR data never leaves the medical centers, only aggregate statistics are exchanged…

Our network is currently composed of 202 hospitals in 12 health systems (11 in the USA and one in Germany), which collectively have electronic health record data from over 45 million patients. Between January 1, 2020 and August 31, 2020, our Consortium had 928,255 patients tested for SARS-CoV-2, 59,074 diagnosed with COVID-19, with 19,022 hospitalized and 2,591 deceased. We have access to data from at least one hospital in every USA state.For this project, no patient-level data are ever transmitted outside of each health system, only data aggregates, and the privacy of individuals and institutions is preserved. We also use a novel, distributed analytics technique to consult data and build multivariate models, in a secure manner Our network started as the patient-centered SCAlable National Network for Effectiveness Research (pSCANNER) and later expanded to the network we have today. We welcome new partnerships to broaden our geographical coverage and the robustness of our answers to COVID-19 questions.”
