MRSA
Methicillin-resistant Staphylococcus aureus (MRSA) is type of the Staphylococcus aureus (staph) bacterium that is resistant to several antibiotics,1 including methicillin, that are commonly used to treat ordinary staph infections.2 In healthcare settings—such as U.S. hospitals, where approximately 5% of patients carry MRSA bacteria in their nose or on their skin—MRSA can cause bloodstream infections, pneumonia, or surgical site infections.3

HO-MRSA
Between 2020 and 2021, a statistically significant 14% increase in healthcare-associated infections (HAIs) attributed to MRSA were reported among national acute-care hospitals.4 The COVID-19 pandemic had not only stymied reduction efforts but also precipitated a rise in invasive healthcare-onset MRSA (HO-MRSA) infections, with increases seen of 12-34% in national MRSA standardized infection ratios in 2020 compared to 2019.

Our Solution

The Study
A medical-surgical intensive care unit (ICU) at a suburban hospital had seen similar increases in HO-MRSA infections—defined as a positive culture on or after the 3rd hospital day—despite no change in clinical practice. Between 2021 and 2022, a prospective study of ActivePure’s advanced photocatalytic oxidation (aPCO) technology was conducted at the high-acuity facility, including baseline and regular post-activation surface samplings. No changes were made or required to the hospital’s cleaning and disinfection practices, trainings, or schedules during this time.

Results

Statistically significant 98% decrease in MRSA surface burden from baseline to final post-activation test.
Statistically significant decrease in HO-MRSA infections—including total elimination during the trial period—when compared to the same timeframe a year prior and the immediate 6 months prior to the study.
99% decrease in average MRSA surface colony-forming-unit (CFU) counts from baseline to final post-activation test (427 to 3 CFU/100cm2).
