Sanitizing Hospital Mattresses: Best Practices And Methods

Hospital mattresses are breeding grounds for harmful bacteria, viruses, and pathogens, which can spread infections. To prevent this, hospital mattresses must be regularly cleaned and disinfected. This process involves using disinfectant wipes, disinfectant solutions, steam cleaning, UV-C light, or chemical interventions. However, improper disinfection can lead to cross-contamination, and current methods are often inadequate or impractical. As a result, hospitals are turning to alternative solutions, such as launderable mattress covers and barriers, which provide an effective and cost-efficient way to maintain hygiene standards and protect patients from infections.

Using UV-C light

UV-C light technology is an effective way to sterilize hospital mattresses and prevent the spread of infection. UV-C light uses a specific wavelength of ultraviolet light to create a germicidal effect on pathogens, rendering them inactive and unable to replicate or reproduce. This process is advantageous as it does not rely on antibiotics to be effective, which is crucial in combating antimicrobial-resistant pathogens.

UV-C light technology can be utilized in various hospital environments, including intensive care units (ICUs), operating rooms, and patient rooms. It is particularly useful in areas with a high risk of infection or rapid bed turnover, serving as an efficient disinfecting system that reduces the time and labor required to prepare rooms for the next patient.

When using UV-C light to sterilize hospital mattresses, it is important to ensure complete exposure of the mattress to the UV-C light. This can be challenging, as UV-C light cannot penetrate through bedding or textiles. One approach is to remove the mattress from the facility, vacuum both sides, and then expose it to UV-C light, dry steam, ozone, and infrared heat. While this method is effective, it is relatively expensive and may not be practical for daily use in hospitals.

Another option is to use a UV-C mattress vacuum, which combines powerful suction with UV-C light to kill bacteria and remove debris. These vacuums are designed to attract dust and mites, and some models offer a drying function to eliminate bacteria-causing moisture. However, it is important to note that UV-C technology does not remove pathogens from surfaces but rather inactivates them, and the optimal values for effective disinfection are still being determined.

To maximize the effectiveness of UV-C light, certain environmental conditions should be considered. The light is most effective at a spectrum of wavelengths containing 260 nm, in an environment with low relative humidity, and at room temperature. Additionally, it is important to address health and safety risks associated with UV-C technology when used in proximity to people.

Steam cleaning

To steam clean a hospital mattress, first, check the material of the mattress to see if it can be steam cleaned. If so, strip the bed of the protector and other bedding and wash them. Remove the pillows, comforters, blankets, sheets, and the mattress topper to ensure the mattress is completely exposed. Machine wash all blankets, sheets, and other bedding. Then, use a vacuum cleaner to remove surface-level debris and dirt. Use the hose attachment and the rotating brush when vacuum cleaning. Run the vacuum over areas that are in frequent contact with the skin for longer to suck up loose fibers, dust mites, dirt, and dead skin.

Next, use a powerful steam cleaner, such as a commercial steamer, which can heat water to high temperatures. If renting one, check its specifications to ensure the water will get hot enough. If you cannot afford a steaming machine, use an iron box with a steaming function. Avoid a household carpet steamer as its water temperature is not ideal for killing bed bugs, bacteria, or dust mites. Most steamers have a wand to apply steam, a tank for water, and a motor to generate heat. Fill the tank with water up to the recommended level.

Finally, ensure the mattress dries quickly and adequately to prevent mold and mildew growth. It is best to do this on a sunny day, as sunlight can help dry your mattress quickly. Place the mattress outside, directly in the sun, or in front of an open window. Run a fan in the room to minimize any musty odors and to help the mattress dry.

Chemical disinfection

Before beginning the disinfection process, remove any bedding, sheets, and pillowcases from the mattress and launder these items separately according to the manufacturer's instructions. It is also recommended to wear appropriate personal protective equipment (PPE), such as gloves, and if necessary, a gown and mask.

When choosing a disinfectant, it is important to consider the pH level. Manufacturers recommend using disinfectants with a pH of 5-9. It is also recommended to avoid using quaternary ammonia compounds on soft surfaces like mattresses, as this use is considered "off-label".

One example of a chemical disinfectant is a solution of hydrogen peroxide, which can be used to remove urine, sweat, and blood stains from a mattress. This solution is also effective at killing germs. However, it is important to follow the application instructions carefully and ensure that the mattress is dry before covering it with bedding.

Another important consideration is the potential impact of disinfectants on the mattress surface fabric. Disinfectants can degrade the fabric over time, making it more difficult to disinfect and increasing the risk of contamination. Therefore, it is recommended to routinely inspect mattresses for damage and follow the manufacturer's instructions for cleaning and disinfection.

Laundering mattress covers

Mattress covers in hospitals serve as a protective barrier, preventing blood and other body fluids from penetrating the inner core of the mattress. Over time, these covers can wear out, leading to fluids leaking into the mattress. This poses a significant risk of infection for subsequent patients using the bed. To mitigate this risk, hospitals should implement regular inspections of mattress covers to identify any signs of damage or wear, such as cuts, tears, cracks, or stains.

When laundering mattress covers, it is vital to follow the manufacturer's guidelines and choose disinfectants or cleaners that are compatible with the fabric. For vinyl fabrics, phenolic disinfectants are recommended, while urethane materials require quaternary ammonium compounds. If both vinyl and urethane fabrics are used, hypochlorite and chlorine oxide are ideal for cleaning. It is important to note that concentrated disinfectant solutions may damage the fabric, so caution must be exercised.

In addition to laundering, other methods can be employed to disinfect mattress covers. Surface wiping with disinfectant wipes or cloths soaked in disinfectant solutions is suitable for regular maintenance and quick disinfection. Steam cleaning, utilizing high-temperature steam, is an eco-friendly and effective method for killing bacteria, viruses, and pathogens. UV-C light disinfection is another option, but it should be used carefully as it can be harmful to the skin and eyes.

By diligently laundering and disinfecting mattress covers, hospitals can maintain a safe and hygienic environment for patients, reducing the risk of infections and safeguarding the well-being of those in their care.

Rinsing and drying

Rinsing the mattress is necessary to remove any residual cleaning products or disinfectants that could be harmful to patients or compromise the integrity of the mattress. This step is especially important when using chemical interventions, as improper sanitization can lead to cross-contamination and the spread of pathogens. It is crucial to follow the manufacturer's instructions for the specific disinfectant or cleaning solution being used, paying attention to the recommended contact time and rinsing procedures.

For rinsing, plain water can be used, or a mild soap solution may be recommended to neutralise any chemicals and restore the mattress's pH balance. Warm water is generally suitable, but hot water may be required for certain disinfectants to ensure they are effectively removed. A gentle, low-pressure rinse can help avoid oversaturation of the mattress, especially if it is made of absorbent materials.

Drying the mattress is a critical step in the sterilisation process. Incomplete drying can lead to the growth of mould and bacteria, undoing the benefits of sterilisation. Drying methods can vary depending on the mattress material and the resources available. Sunlight and fresh air are natural drying agents, and placing the mattress outdoors or near an open window can accelerate the drying process. Additionally, mechanical fans or blow dryers can be used to speed up evaporation and ensure the mattress is completely dry.

In some cases, baking soda may be sprinkled onto the mattress surface after rinsing. Baking soda helps absorb moisture, and its antibacterial properties can further enhance the sterilisation process. Vacuuming the mattress after sprinkling baking soda can help remove any residual powder before making the bed. Ensuring the mattress is thoroughly dried is crucial before replacing the linens and putting the bed back into use.
