Air Quality and Contamination

Review Article: Aerobiology and Its Role in the Transmission of Infectious Diseases

Aerobiology plays a fundamental role in the transmission of infectious diseases. As infectious disease and infection control practitioners continue employing contemporary techniques, the central variables affecting the airborne transmission of pathogens are becoming better known.

Aerobiology Papers

Aerobiology and Infectious Disease Transmission

A. Fernstrom, M. Goldblatt, Hindawi 2012. There is a lack of industry standards for evaluating new technologies that attempt to solve the airborne particle transmission problem.

Airborne contamination of wounds in joint replacement operations

O.M. Lidwell, et al. Journal of Hospital Infection 1983. The greater part of bacterial wound contamination in total joint replacement is derived from the air.

Airborne Nosocomial Infection

T. Eickhoff, MD. Infection Control and Hospital Epidemiology, 1994. Airborne transmission appears to account for about 10% of all endemic nosocomial infections.

Air Contamination for predicting wound contamination

G. Birgand, PharmD, PhD. AJIC 2015. There is a strong correlation between air particle counts and microbial contamination, suggesting that particle counting can be used for routine evaluation of contamination in the OR ventilated with turbulent airflow or LAF.

Air Treatment Systems for controlling HAIs

W. Kowalski, PhD, HPAC Engineering 2007. The change that perhaps would have the greatest impact on nosocomial infections in this country is the establishment of national standards concerning aerobiological quality.

Economic Burden of PJI

S. Kurtz, PhD, et al. JOA 2012. Periprosthetic joint infection (PJI) is a challenging complication associated with total joint arthroplasty.

The Importance of airborne bacterial contamination of wounds

W. Whyte,et al. Journal of Hospital Infection 1982. This study revealed facts that suggest 98% of bacteria in patients’ wounds came directly or indirectly from the air.

OR Ventilation with Laminar Airflow

C. Brandt, M.D., et al. Annals of Surgery 2008. OR ventilation with laminar airflow showed no benefit and was even associated with a significantly higher risk for severe SSI after hip prosthesis.

Preventing SSI

D. Chauveaux, Ortho Traum S&R 2015. Intra-operative SSI prevention rests on a combination of multiple measures.

Prevention of airborne infection during surgery

F.H. Howorth, The Lancet, 1985. 80-90% of bacterial contaminants found in the wound after surgery come from CFUs present in the air of the OR.

Proceedings of the International Consensus Meeting on Periprosthetic Joint Infection

Parvizi, J MD, FRCS, Gehrke, T MD, Orthopaedic Research Society 2014. Operative Environment: Consensus recognizes airborne particulate bacteria are a major source of contamination in the OR environment.

Traffic Flow in the OR

A. Andersson RN, et al. AJIC 2012. Traffic flow has a strong negative impact on the OR environment. The results of this study support interventions aimed at preventing surgical site infections by reducing traffic flow in the OR.

Ultraclean air and antibiotics for prevention of postoperative infection

O.M Lidwell, et al. Acta Orthop. Scand., 1987. The basis of the results and the incidence of joint sepsis in relation to them, recommendations have been made for standards of air contamination.
