Who Owns the Clean? Clarifying Roles in OR Environmental Hygiene

When it comes to environmental hygiene in the OR, role confusion remains a persistent challenge. And it often stems from teams not knowing who is responsible for cleaning what.

A study by Hung et al. found that only 37 percent of environmental services personnel always know what they are responsible for cleaning.

A Common Cleaning Conundrum

Without clear role expectations or communication, each person assumes someone else addressed the anesthesia machine knobs, IV poles, tourniquet pump, and other device surfaces. The result is that key high‑touch surfaces go uncleaned — giving lingering pathogens the chance to spread to the next patient.

Clarifying Who Owns the Clean

Teams can leverage new evidence in the just updated Guideline for Environmental Hygiene to create clearer role definitions and shared expectations for cleaning the OR, especially during busy surgical days.

Here are two evidence-based recommendations from the guideline update to consider.

Define "Who Cleans What" Clearly and Visibly

Posting a "who cleans what" matrix—covering key OR surfaces, equipment, and turnover tasks—anchors the team in shared expectations and eliminates guesswork. Clear communication keeps everyone aligned and able to sustain improvements over time, reinforcing the importance of clearly defining tasks, responsible personnel, frequency, and required products.

Build a Culture Where Environmental Hygiene Is a Shared Priority

Cleaning consistency starts with improving daily environmental hygiene collaboration by...

• Implementing quick check-ins during turnovers to help integrate environmental services personnel into the perioperative team. This can strengthen communication and align everyone around the same goals.
• Reinforcing this culture by recognizing environmental services contributions, supporting their education, and including them in key discussions, signaling that environmental hygiene is central to patient safety.
