CORRELATION OF THE AIR–SURFACE NEXUS OF BACTERIAL BURDEN DURING ROUTINE PATIENT CARE
Bischoff, W., MD, Russell, G. MS. Infection Control & Hospital Epidemiology (2020), 1–2
Significantly reduced both surface and airborne bacteria in critical care units by ~51% and 58%, respectively.
REDUCTION OF PARTICLES IN THE OR USING UV AIR DISINFECTION UNITS
Curtis, G.L., MD, et al. The Journal of Arthroplasty, 2017 reported the C-UVC units significantly reduce total and viable particles counts.
THE IMPACT OF SUPPLEMENTAL INTRAOPERATIVE AIR DECONTAMINATION ON THE OUTCOME OF TOTAL JOINT ARTHROPLASTY
Cook, T., DO, Piatt, C., DO, Barnes, S. BSN, Edmiston, Jr., C.E. PhD. The Journal of Arthroplasty, 2018. While PJI is multifactorial in nature, this study suggests the use of intraoperative supplemental air decontamination significantly reduced the overall risk of PJI.
THE IMPACT OF A NOVEL MAPS ON THE BACTERIAL AIR BURDEN DURING ROUTINE CARE
Werner Bischoff, MD PhD, FSHEA, Gregory Russell MS, Elisabeth Willard AAS, John Stehle Jr PhD. American Journal of Infection Control, 2019. Aerosol transmission of pathogens can result in the rapid spread of disease. The mobile air recirculation system significantly decreased the bacterial load by over 40%.
REDUCTION IN AIRBORNE BACTERIAL LEVELS USING SUPPLEMENTAL SYSTEM
W. R. Walsh, PhD, Airborne bacteria-laden particles in healthcare settings are now being recognized as a contributing cause of hospital acquired infections (HAI), and surgical site infections (SSI). OR Air Supplemental System reduced mean bacterial CFU/m³ by 57%.
DIATHERMY STUDY UTILIZING ILLUVIA 500UV
W.R. Walsh conducted a diathermy study utilizing Illuvia 500UV that found reduction in the airborne particulate count.
OUTCOME STUDY SEM OF OPERATING THEATRE AIR
W.R. Walsh, PhD., conducted a study with scanning electron microscopy to evaluate the Illuvia filtration cartridge. A significant number of airborne particulates was detected within the cartridge after each surgical procedure.
ABX OUTCOME STUDY: SSI REDUCTION RESULTS
AEROBIOTIX technology previously demonstrated statistically significant reductions in total airborne particulates, viable particulates, and airborne bacteria when deployed in active operating rooms. The study was performed in a single OR at a 300-bed community medical center in Atlanta, Georgia, USA.
ELIMINATION OF AEROSOLIZED VIRUS IN SINGLE-PASS TESTING
The Research Triangle Institute (RTI) Center for Microbial Community Systems and Health Research conducted a series of tests to determine the efficiency of viral inactivation by the Aerobiotix in–room recirculating air cleaner. MS2 virus inactivation efficiency of the Aerobiotix air cleaner was 100% observed when the unit was operated in “full on” mode.
MITIGATION OF AIRBORNE CARDIAC HEATER-COOLER EMISSIONS USING THE HUAIRS
Carrico, R.M. PhD DNP FSHEA CIC, Warye, K. The HUAIRS system represents a potential solution for the mitigation of bioaerosol emissions in order to eliminate SSI risk due to HCU in cardiac ORs.
Effect of portable negative pressure units on expelled aerosols in the operating room environment
Marko Popovic, Jonathan Beathe, Ejiro Gbaje, Marla Sharp, Stavros G Memtsoudis. With the portable negative pressure unit 10 cm and 30 cm from the site of aerosol emittance, the median concentration compared with background concentration was −0.5 (−8,8) particles/ft 3/min and 398 (89, 1749) particles/ft 3/min, respectively.
THE CASE FOR IMPLEMENTATION OF OPERATING ROOM AIR DECONTAMINATION TECHNOLOGY FOR ORTHOPEDIC SURGERY
Russell Nassof, JD; Kathy Warye, Maureen Spencer, MEd, RN, CIC, FAPIC. Infection Control Today, September 2018. While there is a host of factors in OR environment and practice that can contribute to SSI, there is a growing body of evidence which suggests that air quality merits heightened attention on the part of the infection prevention community.
INACTIVATION OF VIRUS-CONTAINING AEROSOLS BY ULTRAVIOLET GERMICIDAL IRRADIATION
Chun-Chief Tseng and Chih-Shan Li, National Taiwan University, Aerosol Science and Technology, 2005.
Study: to evaluate the application of UVGI for the inactivation of viruses. Conclusion: UVGI was an effective method for inactivation of airborne virus.
