Responding To Dual Epidemics of COVID-19 and Overdose Among People Who Inject Drugs in Wisconsin

Using the COVID EHR Cohort at the University of Wisconsin (CEC-UW), this project aimed to analyze the disproportionate impact of COVID-19 on racial and ethnic minority groups in Wisconsin, compare disease outcomes between UW Health and other health systems and test associations between risk factors, treatments and vaccine status with disease outcomes. CEC-UW has been collecting electronic health record (EHR) data from all COVID-19 patients across 21 participating health systems and, as of September 2021, has compiled more than 250 EHR elements from 1.1 million COVID-19 patients. This data has the potential to help target high-risk individuals, improve treatment, guide variant management and enhance response to future disease outbreaks. The results revealed that Black and Hispanic communities, along with low-income groups, faced significantly higher infection rates and more severe COVID-19 outcomes. Comparison of outcomes between health systems showed that UW Health patients had better recovery rates and lower mortality due to more effective health strategies, including advanced treatment protocols and higher vaccination rates. Finally, the project found that early treatments and full vaccination greatly improved outcomes, while those with underlying conditions or lack of vaccine access faced worse outcomes.
