Investigation of the fungal and bacterial contamination in indoor units and outdoor air of Kashan Beheshti hospital in 2018

Background: The health of patients with weakened immune systems is endangered by presenting of bacteria and fungi in the internal units of hospital as well as development of nosocomial infections in them. The current article aimed to investigate the bacterial and fungal contamination degree in internal units and outdoor of the hospital in which some points are mainly considered such as the nosocomial infections and the discussion of improving the quality of hospital spaces and providing appropriate conditions to maintain the health of patients. Materials and Methods: This study is a cross sectional study conducted in Kashan Beheshti hospital in 2018. Air sampling is done by direct bacterial sampler (Quick Take 30) along with identification of type and the number of fungi and bacterial colonies including 180 samples from internal units and outdoor spaces. Data was analyzed statistically by SPSS 22, EXCELL and BONFERRONI test. Results: The obtained results from 180 samples showed that bacterial and fungal contamination among 180 samples was 97% and 47.8%, respectively. Also, the most bacterial and fungal contamination presented in medical units and outdoors, respectively. Conclusion: The results revealed that the micro-organism concentration in internal units is more than in outdoors that results can be related with the presence of the patients, air conditioning and inappropriate cleaning. For this reason, improving sanitation standards and setting the appropriate air-conditioning are suggested in internal units of the hospital.
