CEC-UW Project Timeline

Here’s a look at the overall timeline for the project.

April to June 2020: Project Initiation

  • Solicited and secured project participation from 21 health systems
  • Defined project parameters including providing electronic health record (EHR) data for all patients with a COVID case starting on February 1, 2020
  • Obtained University of Wisconsin (UW) IRB Exemption approval for project
  • Identified discrete EHR data elements of interest (about 195 elements), all of which are HIPAA-compliant and de-identified (per HIPAA requirements)
  • Provided a unique de-identified patient identifier for each patient included in the cohort. The unique identifier allows for tracking of additional treatments provided by the same health system after the initial COVID diagnosis
  • Completed data transfer and use agreements with each of the 21 health systems
  • Contracted with BlueTree to consult on use of EHR data
  • Defined a COVID case as PCR+ for COVID and/or ICD-10 Code+ for COVID and/or Antibody+ for COVID

July to September 2020: Initiated Data Extraction

  • Assisted health systems with EHR coding and extraction
  • Completed first monthly data transfer from 21 health systems (data from February 1 – June 30, 2020) in early July
  • Corrected and refined EHR coding across the 21 health systems
  • Aided each health system with unique EHR data challenges (ongoing)
  • Merged data across 21 health systems to evaluate summary data for the first time

October to December 2020: Continued Data Extraction and Produced first Analyzable Data Set Findings

  • February – October 2020 data from 21 health systems was merged and reviewed for integrity and quality. Corrections to data inaccuracies were made
  • EHR code was refined and optimized
  • Began testing analyses with harmonized data set
  • Invited co-investigators to submit research ideas

**2020 total sample size – approximately 620,000 discrete patients with COVID case

2021 (Planned Activities)

  • Complete data collection from 21 health systems for 2020 (February 1 – December 31, 2020)
  • Finalize data dictionary
  • Solicit participation from the same 21 health systems to continue project in calendar year 2021
  • Prepare and submit first manuscripts
