Minimizing Sources of Airborne, Aerosolized, and Contact Contaminants in the OR Environment

Area of Science:

• Infection Control
• Surgical Safety
• Healthcare Management

Background:

• Surgical site infections (SSIs) are common complications of surgery.
• SSIs cause patient harm and incur significant financial costs for healthcare systems.
• Extrinsic factors within the operating room (OR) environment can increase microbial contamination, leading to SSIs.

Purpose of the Study:

• To highlight the role of extrinsic factors in operating room microbial contamination.
• To emphasize the importance of preventive practices in reducing surgical site infections.
• To guide perioperative leaders and healthcare providers in mitigating SSI risks.

Main Methods:

• Review of extrinsic factors influencing microbial contamination in the OR.
• Identification of simple preventive practices to reduce microbial load.
• Emphasis on proactive strategies to break the chain of infection.

Main Results:

• Healthcare providers' behaviors and OR environmental factors can increase microbial contamination.
• Airborne and contact routes are primary pathways for microbial transmission to surgical incisions.
• Implementing basic preventive measures can decrease microbial contamination levels.

Conclusions:

• Proactive preventive practices are crucial for reducing surgical site infection risk.
• Controlling extrinsic OR factors and adhering to hygiene protocols are essential.
• Perioperative leadership plays a key role in implementing infection prevention strategies.
