ABSTRACT
For controlling the nosocomial infections in the hospitals, use of sterilizer devices such as: steam autoclave, chemiclave, Gas plasma, Oven and Vaporized Hydrogen Peroxide are approved. According to standardized directions, these equipments needs to be tested physically, chemically and biologically continuously. The most trusted way for sterilization monitoring is the biologic one. The main purpose of this study is to assess the performances of the sterilizer devices, that are presented in affiliated hospitals to Tehran University of medical sciences with biologic monitoring way. This is a cross - sectional study conducted in all 135 devices that are presented in CSR units of 14 hospitals and related responsible staff. In this study, sterilization process was assessed by using of spores, microbial vials and culturing of the samples and also, the Knowledge of CSR personnel was measured by a valid and reliable questionnaire. We have used, T-Test for data analysis in this study. 14 out Of 135 devices [10.4%] were not in good function, there was a significant relationship between age of personnel and their knowledge. There were significant relations between the sex [0.001], educational grade [0.02], years of experiences, and the knowledge of the staff [P=0.001] and also CSR unit area in this study. This study suggests that hospitals must have CSR units with sufficient area and educated personals in related fields. They must also regularly educate the staff, especially males that are responsible in CSR units
