Risk of mortality associated with nosocomial infections in health centers as a problem has always existed. These infections can be transmitted through contact with the environment or equipment to patients. Therefore, the present study was conducted with the aim of evaluating the frequency of bacterial contamination in different parts of the center Educational and therapeutic center in Qaen Shohada Hospital during the years 2011-2016.

Finally, the data were analyzed by SPSS software (version 20) and analyzed using Chi-Square tests and Fisher exact test. The results of this study showed that of 1758 samples, 542 cases (30.8%) had bacterial contamination. The most bacterial strains were gram-positive (77.3%). Among the different parts of the hospital, the highest contamination was found in the kitchen (75%) and then the internal section (51.3%). Among the equipment that was cultured on the bacteria, the most contamination was related to medical equipment (69.3%). The study showed that bacterial contamination levels and departments of different hospitals are significant. The use of standard preventive and controlling infectious disease guidelines can be effective in reducing these infections
