Summary
Portable UV-C disinfection effectively reduced contamination on frequently used medical equipment. This method significantly lowers colony forming units (CFUs), enhancing patient safety by reducing healthcare-associated infections.
Area of Science:
- Microbiology
- Infection Control
- Environmental Services
Background:
- Healthcare equipment mobility increases contamination risk.
- Communication gaps exist between nursing and environmental services regarding cleaning.
- Standard cleaning protocols may be insufficient for high-touch items.
Purpose of the Study:
- To evaluate the efficacy of a portable UV-C tent with a UV-C device (Xenex LightStrike Robot) for disinfecting medical equipment.
- To assess the reduction in microbial contamination on high-use equipment after UV-C treatment.
Main Methods:
- Healthcare equipment was sampled for colony forming units (CFUs) before and after UV-C disinfection.
- Standard microbiological techniques were used for CFU enumeration.
- A portable UV-C tent system was employed for disinfection.
Main Results:
- A significant reduction in CFUs was observed, from 17.08 to 0.45 (P<.05).
- UV-C treatment demonstrated near elimination of microbial contamination.
- The study highlights the effectiveness of UV-C disinfection for high-touch surfaces.
Conclusions:
- UV-C disinfection offers a valuable addition to current cleaning practices for ensuring adequate equipment disinfection.
- Implementing UV-C technology can help break the chain of infection and reduce healthcare-associated infections.
- Further research is needed to optimize cleaning protocols incorporating UV-C technology.

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

01:26Physical Methods for Controlling Microbial Growth: Radiation and Filtration
Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
