Nicholas A Turner, Jason E Stout, Jeffrey D Jenks

TL;DR
The study examines how mortality rates from COVID-19 have changed over time within a US academic health system from 2020 to 2025.
Contribution
The study provides new insights into the evolving mortality trends of COVID-19 compared to influenza within a specific health system.
Findings
30-day mortality rates after a positive COVID-19 test have decreased over time.
Adjusted mortality rates remain higher than those for influenza.
Mortality trends were analyzed within a single academic health system from 2020 to 2025.
Abstract
Coronavirus disease 2019 (COVID-19) was initially associated with higher mortality than other respiratory viruses. We assessed trends in mortality following a positive COVID-19 test within a single academic health system. Among individuals with COVID-19, 30-day crude and adjusted mortality rates have decreased but remain numerically similar to higher than influenza.
