Investigators Examine Success and Failures in MRSA Control During the COVID-19 Pandemic

Kavanagh and Cormier (2022) say that private-sector facilities in the United States have experienced a resurgence of methicillin-resistant Staphylococcus aureus (MRSA) hospital-onset infections during the COVID-19 pandemic, which eliminated all gains that were achieved over the last decade.

They report that, "The third quarter of 2021, the Standardized Infection Ratio for hospital onset MRSA bloodstream infections was 1.17, well above the baseline value of 1.0. In contrast, the Veterans Health Administration (VHA) has been able to maintain its mitigation efforts and low rates of MRSA hospital-onset infections through the second quarter of fiscal year 2022 (Mar. 31, 2022), the most recent available data. The difference may be explained not only by the VHA’s use of uniform mitigating policies which rely on active surveillance and contact precautions, but also on the VAH’s ability to maintain adequate staffing during the pandemic. Future research into MRSA mitigation is warranted and this data supports the need for healthcare system transformation."
