Transmission of potential microorganisms from the external environment to patients is one of the growing concerns, especially in operation theaters (OTs) where there is increased contact between patient and care provider's hands and environmental surfaces. Approximately 50% of surfaces are not adequately disinfected during between-case or terminal cleaning, and can harbor pathogenic organisms such as Pseudomonas spp, Acinetobacter spp, and Klebsiella spp. Hence, adequate disinfection of OTs is very essential. Recent advances have shown that ultraviolet (UV) light devices have been shown to decrease OTs' pathogen burden. The research was carried out in an advanced tertiary care hospital; the objective was to study whether UV rays can effectively reduce the burden of pathogenic microorganisms (Clostridium difficile and methicillin-resistant Staphylococcus aureus) and other multidrug-resistant organisms. The study also incorporated to assess whether the UV rays can effectively reduce surgical site infection (SSIs) rates and to know the implication of UV technology usages. Experimental research design was collected primary data. Samples from six operation rooms were collected for quantitative culturing using swabs and thioglycolate broth and Gluco broth culture bottles. The study found that UV disinfection was highly effective in all the six OTs.
