Introduction: Microbial contamination of operating theaters (OTs) is a major cause of nosocomial infections (NIs). Purpose: Thus, the purpose of this systematic review was to determine the degree of contamination present on OTs and to evaluate the methodological quality of this evidence. Materials and Methods: Published studies from December 2000 to December 2012 were identified in nine major databases. Methodological quality was evaluated using a quantitative critical appraisal tool. Data were extracted and analyzed using four major outcome measures. Results and Conclusion: A total of 45 studies were identified investigating the levels of microbial contamination on OTs; of which 26 were included in the review. The included studies reported that 51.3% of all sampled air/articles/surfaces of OTs were contaminated. However, the majority of microbial contamination and hence any risk of acquiring a NIs can be reduced substantially by implementing the infection control measures. Further research is also required on the role of OTs in NIs.
