airPHX Reduces CLABSI HAI by 50%, Saving Hospital System $1,000,000
In January 2018, a multiple acute care hospital system in the Northeastern USA tested a single airPHX PA2400 unit on the oncology floor of its flagship medical center, a 500+ bed tertiary care hospital. The airPHX unit ran for a period of 18 days in a treatment space of approximately 15,000 square feet.
Air and surface testing were conducted on the oncology floor, while air testing was conducted in the elevator lobbies on each floor of the hospital. Longitudinal data gathered by an independent testing lab shows airPHX significantly reduced the bioburden in those areas. In fact, airPHX achieved a virtual 100% reduction of air and surface contaminants on the oncology floor, as well as a 96% reduction of contaminants in the various elevator lobbies. Those contaminants that saw a reduction included: mold, bacteria, flu, E. coli, C. diff, MRSA, and coronavirus.
Specific test results were:
Air: 94.8% reduction
Surface: 98.8% reduction
Pre-Treatment Results: 767 cfu/m3
Pre-Treatment Results: 17 cfu/cm2
Post-Treatment Results: 40 cfu/m3
Post-Treatment Results: 0.21 cfu/cm2
Based on those results, the hospital system elected to conduct its own testing and acquired additional airPHX units in order to ascertain what effect airPHX units would have on various healthcare-associated infections.
"airPHX achieved a virtual 100% reduction of air and surface contaminants on the oncology floor, as well as a 96% reduction of contaminants in the various elevator lobbies."
In its own study, the hospital system evaluated the impact of airPHX on Central Line Infections on the transplant floor over a twelve-month period. The study commenced with a deployment of two additional airPHX units in January 2019. The chart below shows the actual number of Central Line Infections per 1000 Line Days, both pre- and post- deployment of the two airPHX units. Besides the use of airPHX, no other significant changes were made to the hospital’s standard infection control or clinical procedures over the testing period.
Following the impressive results of the airPHX study, the hospital system has since stated it expects the value of its return on investment to exceed $1,000,000 in the first year of using airPHX alone. The hospital system has since deployed numerous additional units.
