Proper Cleaning of Hospital Operating Rooms: Adhering to AORN Standards and Joint Commission Requirements

Hospital operating rooms (ORs) are critical environments where cleanliness and sterility are paramount to patient safety. The meticulous cleaning and disinfection of ORs play a crucial role in preventing healthcare-associated infections (HAIs), ensuring compliance with regulatory standards, and maintaining the trust of patients and healthcare providers. The Association of periOperative Registered Nurses (AORN) and the Joint Commission provide comprehensive guidelines and requirements to standardize the cleaning and maintenance of ORs. This essay explores the essential practices for cleaning operating rooms, focusing on AORN standards and Joint Commission requirements, while highlighting best practices for ensuring a safe and sterile environment.

The Importance of Operating Room Cleanliness

Operating rooms are environments where invasive procedures expose patients to risks of infection. Contaminants, including blood, bodily fluids, and microorganisms, can accumulate on surfaces, equipment, and air systems during surgical procedures. Failure to properly clean and disinfect these spaces increases the likelihood of surgical site infections (SSIs), prolonged hospital stays, and added healthcare costs.

AORN and the Joint Commission emphasize that cleaning operating rooms is not merely a custodial task but a vital infection prevention measure. Compliance with their guidelines ensures that cleaning processes are evidence-based, systematic, and consistent across healthcare facilities.

AORN Standards for Operating Room Cleaning

The AORN “Guidelines for Perioperative Practice” provide evidence-based recommendations for cleaning and disinfecting ORs. These guidelines focus on three primary cleaning phases: pre-procedure, intra-procedure, and post-procedure cleaning. Below, each phase is detailed in the context of AORN standards.

Pre-Procedure Cleaning

Pre-procedure cleaning ensures that the OR is prepared for the next surgical case. Key tasks include:

1. Surface Disinfection: Cleaning and disinfecting high-touch surfaces such as operating tables, instrument stands, and anesthesia equipment. EPA-registered hospital-grade disinfectants should be used.

2. Equipment Check: Ensuring surgical instruments, lighting, and other equipment are free from dust and debris.

3. Floor Cleaning: Sweeping and mopping the floor with a disinfectant to remove contaminants from prior procedures.

AORN recommends that all pre-procedure cleaning tasks be documented and performed by trained personnel to ensure standardization and accountability.

Intra-Procedure Cleaning

During surgery, contamination can occur from spillage or the spread of biological materials. Intra-procedure cleaning focuses on:

1. Spot Cleaning: Addressing spills immediately to reduce the risk of contamination spreading to other areas.

2. Containment of Waste: Proper disposal of contaminated materials such as surgical drapes, suction containers, and sharps.

Intra-procedure cleaning requires coordination between surgical and environmental services staff to minimize disruptions while maintaining a sterile environment.

Post-Procedure Cleaning

Post-procedure or terminal cleaning is the most thorough phase of OR cleaning and occurs after every surgical case. Key components include:

1. Comprehensive Disinfection: All surfaces, including walls, ceilings, and equipment, are disinfected. High-touch surfaces like light switches, door handles, and monitors require extra attention.

2. Air Quality Maintenance: HEPA-filtered ventilation systems should be operational to reduce airborne contaminants. Some facilities employ ultraviolet (UV) light systems to further disinfect the air and surfaces.

3. Waste Removal: All biohazardous waste is removed and disposed of according to OSHA and EPA regulations.

4. Floor Cleaning: Floors are scrubbed using hospital-grade disinfectants, paying attention to corners and areas under furniture.

AORN emphasizes that post-procedure cleaning must follow a standardized checklist to ensure no area is overlooked. The cleaning staff should also wear personal protective equipment (PPE) to protect themselves from exposure to contaminants.

Joint Commission Requirements for Operating Room Cleaning

The Joint Commission enforces strict standards for environmental cleanliness and safety in healthcare facilities. These requirements complement AORN guidelines and are rooted in the principles of infection control and patient safety.

Environmental Standards

The Joint Commission’s standards are outlined in the Environment of Care (EC) and Infection Prevention and Control (IC) chapters of its accreditation manual. Key requirements include:

1. Cleanliness Audits: Regular inspections to ensure compliance with cleaning protocols.

2. Documentation: Detailed records of cleaning procedures, schedules, and training.

3. Compliance with Manufacturer Instructions: Cleaning agents and disinfectants must be used according to the manufacturer’s instructions for efficacy.

Staff Training

The Joint Commission requires all cleaning personnel to be adequately trained in infection prevention practices. Training includes:

• Understanding the use of cleaning products and equipment.

• Knowledge of infection transmission pathways.

• Proper donning and doffing of PPE.

Hand Hygiene

Hand hygiene is a cornerstone of the Joint Commission’s infection prevention strategy. Cleaning staff must adhere to strict handwashing protocols before and after cleaning ORs to prevent cross-contamination.

Equipment Maintenance

Cleaning equipment, such as mops and vacuum systems, must be maintained and stored properly to avoid reintroducing contaminants. The Joint Commission requires facilities to establish protocols for cleaning equipment maintenance and replacement.

Best Practices for Operating Room Cleaning

In addition to adhering to AORN and Joint Commission guidelines, facilities should implement best practices to enhance the effectiveness of OR cleaning procedures. These include:

Standardized Cleaning Protocols

Establishing clear, step-by-step cleaning protocols ensures consistency and reduces the likelihood of missed areas. Protocols should be updated regularly to reflect new evidence or regulatory changes.

Use of Technology

Automated cleaning systems, such as UV light robots and electrostatic sprayers, can supplement manual cleaning efforts. These technologies improve disinfection efficiency and reduce human error.

Color-Coded Cleaning Tools

Using color-coded mops, cloths, and buckets minimizes the risk of cross-contamination between clean and dirty areas.

Collaboration Between Departments

Effective communication between environmental services, infection prevention, and surgical staff is critical for ensuring a clean and safe OR environment.

Continuous Monitoring and Feedback

Facilities should implement a system for monitoring cleaning effectiveness, such as adenosine triphosphate (ATP) testing or fluorescent markers. Feedback from these systems can guide improvements in cleaning practices.

Challenges and Solutions

Staffing and Training

Challenge: High turnover rates and staffing shortages in environmental services can compromise cleaning quality.

Solution: Facilities should prioritize ongoing training and create a supportive work environment to retain skilled staff.

Compliance Monitoring

Challenge: Ensuring compliance with AORN and Joint Commission standards can be resource-intensive.

Solution: Utilizing digital checklists and audit tools streamlines compliance monitoring and documentation.

Emerging Pathogens

Challenge: New and drug-resistant pathogens present unique disinfection challenges.

Solution: Facilities should stay informed about emerging threats and update cleaning protocols and products accordingly.

Conclusion

The proper cleaning of hospital operating rooms is a vital component of infection prevention and patient safety. Adhering to AORN standards and Joint Commission requirements ensures that cleaning practices are systematic, evidence-based, and effective. By implementing standardized protocols, leveraging advanced technologies, and fostering collaboration among staff, healthcare facilities can maintain clean and safe OR environments. Continuous education, monitoring, and adaptability to emerging challenges will further enhance the quality and reliability of operating room cleaning processes, ultimately safeguarding patients and healthcare providers alike.
