Data source & Databases

Using local (VA) Institutional Review Board approval (#00133238), the VA COVID-19 Shared Data Resource was accessed for collecting patient data for this retrospective study. For this study, the VA COVID-19 Shared Data Resources were used, which is a part of VA Informatics and Computing Infrastructure (VINCI). This shared data resource domain specifically tracks all COVID-19 infected veteran patients within the national VA hospital system with veteran's COVID positivity data traced from the National Surveillance Tool that gathers data from publicly available databases to track COVID-19 cases across the country in real-time. The VA COVID-19 Shared Data Resource domain also collects other pertinent veteran data from the VA Corporate Data Warehouse (CDW) to provide full patient-level data to VA investigators. This shared data is only accessible through the VINCI server. For this reported study, the VA COVID-19 Shared Data Resource was accessed on March 22nd, 2022.
