Effectiveness of DHP® Technology Reducing Air and Surface Microbial Bioburden in a Multicenter Clinical Setting
Published November 2023 in the Infection Control & Hospital Epidemiology
Description: Between November 2021 and May 2022, a study using DHP® technology was conducted in 2 tertiary care hospitals as well as a free-standing emergency department to determine the effectiveness of DHP® in reducing environmental bioburden in occupied rooms.
- Hospital A (306 beds) located in Las Vegas, NV
- Hospital B (273 beds) located in Aiken, SC
- Free-standing Emergency Department located in Henderson, NV
Key Takeaways:
- A total of 1,554 surface and 1,036 air samples were collected from 74 patient areas between the three facilities on three consecutive days pre-DHP® deployment and on days 14, 30, 60, and 90 post-deployment.
- DHP® was associated with statistically significant reductions in air bioburden in Valley Hospital and Aiken Regional Medical Center (p=<0.0001 and p=0.041, respectively), both of which deployed negative pressure ventilation.
- DHP® was associated with statistically significant reductions in surface bioburden at Aiken Regional Medical Center and Henderson ED (p=0.019 and p=0.002, respectively).
- DHP® reduced VOC levels in Valley Hospital and Aiken Regional Medical Center by 75.1% and 72.5%, respectively. Henderson ED had VOC levels below detectable limits before and after the use of DHP®.
