Overview: Hospital acquired infection rates are of huge concern for patients, visitors, healthcare providers, and staff. The devastating repercussions of acquiring an HAI will not only affect the heath of those afflicted, but in the hospitals reputation as well. With allotted cleaning times reduced to fractions of an hour, the expectation of fully and proficiently sanitizing a room is unreasonable. This means that there is a chronic risk of exposure to harmful organisms from a variety of sources, including the air.
A realistic, affordable, and easy solutions is to utilize ultraviolet light as a disinfection method. Ultraviolet light is a specific part of the electromagnetic spectrum of light that offers bactericidal effects. Ultraviolet light is divided into UV-A, UV-B and UV-C rays. It is the wavelengths in the UV-C spectrum, specifically 254 nm, which offer the greatest germicidal potential. When a micro-organism is exposed to UV-C, the nuclei of the cells are altered due to photolytic processes. This process prevents further replication and causes cell death.
UV-C is effective against a wide range of organisms including MRSA, VRE, and Pseudomonas aeruginosa, among many others which are widespread in the healthcare industry. The properties of UV-C light results in a 99% of harmful organisms and spores in just minutes of exposure with a dry, chemical-free, and residue-free method of disinfection. With patients needing to be in their room much of the day, and cleaning times reduced to unmanageable rates to do a proper job, the need for a quick solution in preventing HAI's is vital.
