The Environment of Care Gaps That Put Your Infection Prevention Program at Risk

Practical Infection Prevention Strategies for Cleaning, Disinfection, and Airflow

Welcome to this month’s IP Mentor Monthly Digest—your go-to resource for practical, real-world infection prevention guidance. This month, we’re focusing on the Environment of Care (EOC)—specifically, how cleaning, disinfection, and environmental factors influence infection risk in ways that are often overlooked. From equipment cleaning to airflow, the details matter more than we think.

This Month’s Focus

This month’s focus is on environmental hygiene in practice—ensuring that cleaning, disinfection, airflow, and storage processes are not only defined, but consistently followed.

We’re focusing on:

• Following manufacturer instructions for cleaning and disinfection

• Establishing clear ownership and accountability

• Verifying cleaning effectiveness

• Evaluating environmental risks like airflow, fans, and splash zones

These are the small, daily practices that have a big impact on patient and resident safety.

Program Foundations

When it comes to cleaning and disinfection, the most reliable starting point is always: Manufacturer Instructions for Use (MIFUs)

If instructions aren’t readily available:

• Search the manufacturer’s website

• Contact your sales representative

• Use a targeted online search with the product name or number

Just as important is having a clear policy for shared equipment.

IP Tip: If everyone is responsible, no one is responsible.

Assigning ownership for cleaning after each use creates consistency and reduces risk.

Cleaning & Storage Spotlight

Effective cleaning doesn’t stop at disinfection—it extends to how items are stored.

Clean and dirty items must always be kept separate.

This requires:

• Physical separation (rooms or designated areas)

• Barriers (closed cabinets or covered containers)

• Clear definitions of clean vs. dirty
  

Also consider splash zones:

• Items within 3 feet of sinks or toilets may be at risk

• Avoid storing clean supplies, PPE, and/or medications in these areas

• Use closed or covered storage whenever possible

These small adjustments can significantly reduce contamination risk.

Verification Spotlight

How do you know cleaning is actually effective?

Verification methods include:

Fluorescent markers: Highlight missed surfaces after cleaning

ATP monitoring: Provides measurable data on surface cleanliness

Routine spot-checks are especially important during outbreak investigations or when environmental transmission is suspected.

IP Tip: Rotate surfaces during audits to get a more accurate picture of performance across your facility.

EOC Risk Spotlight: Fans & Airflow

Let’s clarify an area that often causes confusion—fan use in healthcare settings.

According to the Centers for Disease Control and Prevention, not all fans present the same level of risk. The key is understanding how they are used and for what purpose.

Personal Fans (Higher Risk)

These are small, individual-use fans often brought in for comfort.

Common Concerns:

• Can circulate dust and microorganisms

• May disrupt designed airflow patterns (airborne infection isolation rooms)

• Often inconsistently cleaned and maintained

• Can blow air directly from one person to another
  

Best practice: Avoid personal fans in clinical areas whenever possible. If they must be used, ensure strict cleaning, positioning, and risk assessment.

Ventilation-Supporting Fans (Controlled Use)

These include ceiling fans or strategically placed fans used to support airflow and air mixing.

When used appropriately, they can:

• Improve air circulation

• Help dilute airborne contaminants

• Reduce stagnant air pockets
  

CDC-recommended precautions:

• Avoid high-speed settings

• Use low velocity or reverse flow (for ceiling fans)

• Direct airflow toward walls or unoccupied spaces

• Avoid airflow directly between individuals
  

IP TIp: These applications should always be evaluated as part of a facility risk assessment.

Bottom line: Not all fans are equal. Comfort-based personal fans often introduce risk, while strategically used fans can support safer airflow when properly managed.

IP Mentor Insight

Infection prevention in the environment of care comes down to consistency and awareness.

Follow the IFUs.Define responsibilities. Verify your processes. Understand your environment—including airflow.

It’s often the smallest details that have the greatest impact.
