hospital uv disinfection

Healthcare facilities face serious challenges with mitigating the spread of germs and are seeking enhanced methods of sterilization such as hospital UV disinfection systems. Healthcare associated infections (HAIs) cause nearly 100,000 deaths in the U.S. annually with approximately 1 in 25 people contracting an infection from their hospital stay. HAIs cause unnecessary deaths and put patients and staff at an increased risk.

The hospital environment plays a critical role in the transmission of pathogens, as many harmful viruses and bacteria can remain on surfaces for weeks, months and even years. Superbugs which are resistant to antibiotics such as Methicillin-resistant Staphylococcus aureus (MRSA) and Vancomycin-Resistant Enterococci (VRE) pose additional challenges to keeping patients and hospital staff safe from infection.

Challenges in Sterilizing Hospital Rooms and Surfaces

Many challenges exist in preventing the spread of infection in hospital rooms and surfaces. Disease outbreaks have been traced back to many sources such as thermometers, blood pressure cuffs, sinks, and counters in patient rooms and computer keyboards. This puts hospital staff at risk of contracting and spreading dangerous pathogens.

Hospital staff are expected to thoroughly clean patient rooms and use disinfectants known to kill pathogens of a previously infected patient. Some chemical disinfectants may require a long exposure time to provide effective sterilization and may not even be applied to all infected surfaces. Cleaning materials themselves such as mops or cleaning cloths may also become a source of transmission, spreading harmful pathogens rather than eliminating them.

Due to these challenges facing the healthcare environment with ineffective chemical treatments and the resistance of certain pathogens, it is imperative to incorporate enhanced sterilization with hospital UV disinfection.

Enhanced Sterilization with Hospital UV Disinfection

UV disinfection in hospitals is becoming an extremely popular method of assuring protection against the spread of harmful diseases, with a high rate of efficacy. According to a study published by Cambridge University, UV disinfection systems reported >99.99% effectiveness in eliminating resistant pathogens such as:

  • Middle Eastern respiratory syndrome coronavirus (MERS-CoV) which had a reported mortality rate of approximately 36%
  • Severe acute respiratory syndrome (SARS)
  • Mouse hepatitis virus, strain A59 (MHV-A59)

UV sterilization systems provide a high rate of efficacy, although are most effective in hospitals when used in addition to standard cleaning of hard surfaces and should never be considered a substitute for good cleaning practices.

Automatic UV Disinfection Systems for Hospitals

UV disinfection in hospitals is gaining traction due to the high rate of effectiveness and also because of the ability to automate the sterilization process. Many types of hospital UV disinfection systems are available such as:

  • Portable UVC robots and UVC light carts
  • Stationary solutions such as UVC lamps in light fixtures, overhead doors and doorways
  • UVC lamps in HVAC systems to sterilize the air
  • UVC lamps in water systems for clean and sterile water supply

With a wide range of UVC sterilization systems available to incorporate into hospitals and healthcare facilities, automating an effective UV sterilization solution is much more attainable than in previous years. Integrating UV disinfection systems with building management systems allows for facility managers to activate UV light disinfection systems on demand or as an automatic cycle in various areas of the hospital.

Automated hospital UV disinfection systems provide an invaluable benefit to protect patients and staff as well as cost-effective operation with no required labor. Activating automated UV disinfection in operating rooms after surgeries and prior to new patient arrivals adds a protective layer to manual cleaning and can reach into odd places that may get overlooked during manual cleaning processes.

A study published by the National Institute of Health (NIH) in 2013, concluded that an automated hospital UVC system led to a significant decrease in the total number of colony-forming units (CFUs) of many types of organisms including Vancomycin-Resistant Enterococci (VRE), C. difficile and Acinetobacter.

Hospitals can incorporate automated UV disinfection systems in operating rooms, patient rooms, labs, storage facilities and on equipment surfaces. UVC germicidal lamps offer an enhancement to traditional cleaning methods and are proven to be more effective than cleaning with chemicals alone.

Low Pressure Amalgam UV Disinfection Lamps

LightSources provides the widest selection of high-quality pellet and spot amalgam technology in the lamp industry, with both standard and custom engineered solutions available. Our amalgam lamps deliver the same high performance in either vertical or horizontal operations and yield up to three times the UVC output of other lamps comparable in length. Proprietary LongLife+ technology is applied to our amalgam line to reduce output depreciation, contributing to a long useful life of up to 16,000 hours with end-of-life output at 90% of initial UVC output. We offer a wide selection of spot and pellet amalgam lamps with custom sizes, shapes and UVC output available.

Quartz Germicidal Lamps

The type of fused quartz used in the lamp body determines UV wavelength emissions. Low ozone quartz delivers 90% emissions at 254nm, while very high ozone (VH) lamps clear fused quartz emit both 185nm and 254nm. Synthetic quartz is also available for an even higher ozone emission at 185nm. LightSources offers a wide selection of quartz lamps, standard output, high output, Germipak UV Cell germicidal lamps, and U-shaped quartz germicidal lamps.

Soft Glass Germicidal Lamps

Soft glass offers more variety with sizes and shapes than quartz glass with a wide range of operating currents. We engineer soft glass germicidal lamps with the highest in quality material and a wide range of sizes. Soft glass germicidal lamps are an economical option over quartz lamps, with custom shapes and sizes available.
