An Infection Control Guide for Healthcare Facilities and Home Care

Why Do Hospital Mattresses Need Regular Disinfection?

Hospital mattresses come into contact with, and are frequently used by, the patients’ skin, bodily fluids, and infectious materials. Consequently, they pose a considerable risk of accumulating dangerous microorganism such as:

• MRSA (Methicillin-resistant Staphylococcus aureus)

• Clostridioides difficile (C. diff)

• Pseudomonas aeruginosa

• Streptococcus pneumoniae

These microorganisms can persist for hours or several days on a mattress surface, especially within seams, zippers, and porous materials. If a hospital mattress is not disinfected routinely and correctly, it is one of the foremost contributors to cross contamination and the spread of healthcare acquired infection (HAIs).

Proper sanitization of the hospital bed is essential to the infection control management program. Like other healthcare workers, nurses—and in this case, nursing staff/caring staff—are tasked with disinfection, and in this instance, cleaning medical grade mattresses, which is a matter of infection control and patient safety.

Types of Hospital Mattresses and Material Considerations

The choice of mattress dictates the method of disinfection applied. Consider the following types of mattresses:

Foam Mattresses

• Used in general hospital wards and care at home settings.

• Absorbent and may retain moisture.

• Have to be covered with removable, waterproof covers.

Alternating Pressure Mattresses

• Used for the prevention of pressure ulcers.

• Composed of air cells, electronic pumps, and other parts.

• Often TPU or PVC-coated covers to aid in waterproofing.

Medical Mattresses with Waterproof Covers

• Have surfaces of TPU or thermoplastic polyurethanes and PVC or polyvinyl chlorides.

• Seam-sealed and designed for wipe-down ease.

• Resistant to some degree of chemical disinfectants.

Key Note: The outer material used determines disinfectants inclusively and deeper cleaning methods like steam or UV, which are used.

Step-by-Step Disinfection Process

Disinfection of a hospital bed’s mattress entails both cleaning (removing dirt and biological matter) sanitization to eliminate pathogens:

Step 1: Remove Bedding and Covers

• Strip all sheets, blankets, and protective mattress covers.

• These will be laundered per facility guidelines.

Step 2: Pre-Clean

• Scrub stain, blood, or body fluid using a hospital-grade detergent.

• Seams, folds, zipper linings an area of focus.

Step 3: Disinfect

• Use mattress-appropriate an EPA endorsed disinfectant such as disinfectant for the bed’s material.

• Options that may be appropriate include:

  • Bleach-based solutions (sodium hypochlorite)

  • Hydrogen peroxide-based sprays

  • Quaternary ammonium compounds

Step 4: Pay Attention to High-Risk Areas

• For seams and overlapped stitching, use a soft-bristle brush.

• Disinfect zippers, handles, and valves (on air mattresses).

Step 5: Dry Thoroughly

• Allow the mattress to air dry completely, or use a fan or drying unit.

• Disinfectible zippers, handles, and valves (on air mattresses).

Step 6: Replace Protective Covers

• Replace the covers with clean, dry, ideally waterproof, or those that can be machine washed.

• Document the date and the cleaner’s name from the logbook.

💡 Pro Tip: To limit contamination and preserve the effective life of the mattress, put it under waterproof disposable or washable protective covers.

Disinfection Strategies for Different Situations

Routine Daily Care

• Change bed linens every 24 hours.

• Wipe down mattress surfaces weekly or as needed if dirty.

Post-Discharge or Patient Transfer

• Full disinfection of the mattress and bed frame

• Use of UV-C light devices if available

Patients with Suspected or Confirmed Infections

• Utilize high-level disinfectants.

• Wear PPE (gloves, gown, mask, goggles)

• Quarantine the mattress after cleaning if needed

Advanced Disinfection Technologies

Some healthcare facilities incorporate high-efficiency sterilization systems:

• UV-C Disinfection Lamps

  Eliminate microbes, and bacteria by damaging their DNA/RNA. Useful for comprehensive room sterilization.

• Steam Cleaning
  Use financially friendly method of foam steam cleaning that does not use chemicals for non-electronic foam mattresses.

• Ozone Sterilizers
  Cleans smell and microorganisms, but requires high-level security measures.

• Automated Disinfectant Sprayers
  Specialized hospital equipment that sprays EPA registered products onto broad surface areas.

These methods are primarily used alongside manual cleaning rather than exclusively.

Safety and Compliance Guidelines

For effective and safe disinfection, adhere to the following guidelines:

• Use only disinfectant approved by the relevant government bodies (EPA in the USA, CE/NHS for Europe)

• Avoid strong solvents that clean the cutting mat because they would weaken the materials.

• Utilize designated cleaning PPE

• Ensure to record disinfection actions to enable auditing and tracking.

• Inspect mattresses regularly for:

  • Cracks or surface damage

  • Absorption or odor retention

  • Signs of microbial growth

It is recommended to dispose of malfunctioning mattresses as no method will help if they are structurally unsound or deeply contaminated.

Conclusion: Cleaning + Disinfecting = Patient Safety

Strategies to restrict infection from within the hospital environment include understanding the sanitizing procedures for hospital mattresses. Using a combination of specific hygiene practices, disinfection methods, and materials appropriate for the task, primary caregivers and healthcare institutions can achieve the following:

• Prevent cross-contamination

• Prolong mattress lifespan

• Ensure compliance with health regulations

• Most importantly, protect patient health and safety

Education, equipment, and institutionalized routines help improve care in any healthcare system whether it be busy hospitals or home care.
