Abstract Objective In response to COVID-19, the informatics community united aggregate as much clinical data possible characterize this new disease and reduce its impact through collaborative analytics. The National COVID Cohort Collaborative (N3C) is now largest publicly available HIPAA limited dataset in US history with over 6.4 million patients a testament partnership of 100 organizations. Materials Methods We developed pipeline for ingesting, harmonizing, centralizing from 56...
Main objective There is limited information on how patient outcomes have changed during the COVID-19 pandemic. This study characterizes changes in mortality, intubation, and ICU admission rates first 20 months of Study design methods University Wisconsin researchers collected harmonized electronic health record data from 1.1 million patients across 21 United States systems February 2020 through September 2021. The analysis comprised 104,590 adult hospitalized patients. Inclusion criteria for...
Abstract Ecosystem management requires information on habitat suitability across broad scales; however, comprehensive environmental surveys in remote areas are often impractical and expensive to carry out. Intrinsic Potential (IP) models provide a means identify scale those portions of the landscape that can essential for various freshwater fish species. These derived from watershed patterns processes persistent not readily affected by human activities. We developed an IP model rearing...
Available evidence is mixed concerning associations between smoking status and COVID-19 clinical outcomes. Effects of nicotine replacement therapy (NRT) vaccination on outcomes in smokers are unknown.Electronic health record data from 104 590 patients hospitalized February 1, 2020 to September 30, 2021 21 U.S. systems were analyzed assess status, in-hospital NRT prescription, with death ICU admission.Current (n = 7764) never 57 454) did not differ after adjustment for age, sex, race,...
Abstract Background: There is mixed evidence about the relations of current versus past cancer with severe COVID-19 outcomes and how they vary by patient characteristics. Methods: Electronic health record data 104,590 adult hospitalized patients were obtained from 21 United States systems February 2020 through September 2021. In-hospital mortality ICU admission predicted diagnoses. Moderation characteristics, vaccination status, type, year pandemic was examined. Results: 6.8% had (n = 7,141)...
