Brief Summary:
Determine whether operating room air filtration and sterilization with the Aerus system reduces a composite of serious surgical site infections, infection-related complications, and death within 30 days after surgery.

Condition or disease Intervention/treatment
Non-cardiac Surgery Device: Functioning Aerus air filtration/sterilization Device: Deactivated Aerus air filtration/sterilization

Detailed Description:
The investigators primary goal is thus to determine whether filtering and sterilizing operating room air reduces a composite of serious surgical site infections, infection-related complications, and death within 30 days after surgery. The investigators will determine the effect of air filtration and sterilization on serious surgical site infections, and on the cost of care. infections, and on the cost of care.

Groups and Cohorts
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Group/Cohort Intervention/treatment
Aerus air sterilization
Aerus air sterilization system will be used in an operating room, in addition to routine room air filtration
 Device: Functioning Aerus air filtration/sterilization
Two units of Aerus air sterilization system will be used in each operating room, and each will be set to "high." Units used for the trial will be modified internally to be active and will be sealed to prevent operating room personnel from opening the system and determining a unit's status.
Conventional air handling
Only routine room air filtration will be used in an operation room.
 Device: Deactivated Aerus air filtration/sterilization
Two units of Aerus air sterilization system will be used in each operating room, and each will be set to "high." Units used for the trial will be modified internally to be inactivated and will be sealed to prevent operating room personnel from opening the system and determining a unit's status. Units will be inactivated by removing the activated carbon, high-efficiency particulate filter, and ionization chamber. However, the fan will remain active as will the "run" lights.


Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Composite outcome of postoperative complications [ Time Frame: 30 days after surgery ]
    A composite of mortality, major surgical site infection, and healing-related wound complications


Secondary Outcome Measures :
  1. Serious surgical site infection [ Time Frame: 30 days after surgery ]
    Deep or organ-space surgical site infection will be evaluated by analysis of International Classification of Disease revision 10 (ICD-10) diagnosis codes

  2. Cost-of-care [ Time Frame: 30 days after surgery ]
    Our economic analysis will estimate the cost-effectiveness ratio, defined as the difference in average total hospital costs divided by the difference in the proportion with any of the components of the composite, and expressed as average cost per 1 percent improvement in the composite outcome.
