Parameters for data collection	Retrospective data on all diagnostic testing performed on hospitalized adult patients at an academic medical center was obtained from the electronic health record (Epic, Inc.) covering the time period from January 1, 2018 through December 31, 2018. The data extraction also included whether the patients had an active patient portal (Epic MyChart) account by the time of data review (January 1, 2020) and whether specific diagnostic test reports were viewed in the patient portal. The project had approval from the University of Iowa Institutional Review Board.
Description of data collection	There were a total of 826,843 diagnostic test reports on 40,640 unique patients that were ordered during inpatient encounters. The data included whether the patient had an active eletronic health record patient portal account, whether the patient or proxy accessed the diagnostic test reports through the patient portal, and a number of demographic variables. The project was approved by the University of Iowa Institutional Review Board (protocol # 201907709) as retrospective analysis. The data collection also determined whether patients with inpatient encounters also had any diagnostic tests performed in the outpatient setting in 2018. Statistical analyses were performed using SPSS (PASW Statistics 18, Chicago, Illinois).
