Introduction and Objectives: Hospital infections are one of the major causes of mortality in hospitalized patients. Considering the importance of proper diagnosis of bacteria in the hospital infection, important and fundamental steps in the microbiology lab are to identify and identify the bacteria correctly by implementing quality control in the processes before, during and after the bacterial identification. Also, the rate of infection control principles at hospital levels, the average infection rate varies from 5% to 25% on average worldwide. Therefore, considering the importance of the subject, the aim of this study was to evaluate the bacteria by sampling the medical, medical and other environment with the implementation of the above programs. Materials and Methods: In a 3-year period from 1398 to 1396, using standard Haas method and implementing quality control management in the above triple processes, sampling from different areas of the hospital and medical equipment and other areas, identification of bacteria, confirmatory diagnosis Bacteria, response, interpretation, and expression of the importance of isolated bacteria and preventing the spread of bacteria. Results: Out of 4320 samples, 531 isolates of pathogen and peripheral bacteria were isolated from which 95 (17/80%) cases of enterobacteriacea, 120 (22.59%), gram-positive bacilli, 253 (64.6% 47%), micrococcus, 56 (10.54%) non-fermented bacillus and 7 (31.1%) streptococci. Conclusion: This study showed that isolated bacteria in each year had a significant decrease compared to previous years due to the proper attitude of hospital personnel involved with the importance of hospital infection. It can also be noted that the role of quality control meriset in identifying and identifying bacteria in the control and monitoring of possible adverse reactions is denial-of-pump. Increasing the non-standard capacity of the hospital is likely to result in hospital infections in hospitalized patients requiring training and supervision in this regard. Is. Quality control in pre-testing, testing and post-test procedures in microbiology departments of hospitals is carried out repeatedly and accurately, and all records, such as non-compliance and corrective actions, are documented.
