Steps to reproduce

Epic Reporting Workbench (RWB), a software tool for retrieving specific data from the Epic electronic health record (EHR), was used to retrieve all diagnostic test orders (pathology/laboratory and radiology) ordered during hospitalization between January 1, 2018 and December 31, 2018 on patients 18 years and older. With each diagnostic test order, the RWB search also retrieved age, sex (male or female), self-identified race, self-identified preferred language, insurance status, prior hospitalization, presence of outpatient lab reports, and whether patient had a proxy that could legally access their patient portal. Race was categorized as White or race other than White (included African-American, American Indian / Alaska Native, Asian, Hispanic/Latino, Mixed Race, Native Hawaiian / Pacific Islander, Other, Unknown and Declined), language as English or Non-English (included a total of 75 other languages with the six most common other than English being Spanish, Arabic, French, Chinese, Swahili and Vietnamese) and insurance as commercial payor or public insurance (Medicare or Medicaid)/uninsured. Data was also analyzed by testing category. Pathology/laboratory tests were categorized as Anatomic Pathology (including surgical biopsies and resections, cytopathology, and dermatopathology), Chemistry (includes toxicology, therapeutic drug monitoring, and clinical chemistry), Hematology, Microbiology, and Send-out (referred to outside reference laboratories). Imaging tests were categorized as computerized tomography (CT) scan, magnetic resonance imaging (MRI), nuclear scans, and X-rays.
