Abstract

Abstract Background and Objective: The most important way of releasing hospital infections has been the lack of attention to the sterilization of medical equipment.According to the important roleof sterilization in preventing infections, the purpose of the present study is to monitor the function of equipment’s sterilization in health centers affiliated to the Hamadan University of Medical Sciences based on ISO standard using mechanical, chemical, biological methods. Materials and Method: This study is descriptive–analytical and cross-sectional. 40 autoclave and dry heat devices were evaluated in16 health centers. Sterilization devices were evaluated by 3methods,simultaneously among 2 stages within 3 months. Mechanical indicators of devices were evaluated during sterilization.Chemical method was done by class 6 autoclave when dry heat glass indicators and biological method were used by bacterial spore containing vial. Findings: Biologic markers showed that autoclaves were evaluated in two optimal stages, although dry heat device showed failurein 7.5 % of the first stage and 10% for the second stage of sterilization. Chemical indicators showed the same results in the both stages with biological tests which demonstrates that both methods’results are matched (P<0.001,Kappa=1). Results showed that 3 first stage error and 4 second stage error were not shown by mechanical markers. Conclusion: The percentage of sterilization fracture was higher than the autoclave.Theweekly use of biological indicators and chemical indicators at each sterilization would ensure the effectiveness of device and mechanical indicators.When the biological tests are not available, chemical indicators are found to be simple and inexpensive control test with a minimum response time.
