Analysis on Relationship between Bacillus and Enterobacter Bacteria in Air with Hospital Acquired Infections Potential in Intensive Care Unit of Dr. Wahidin Sudirohusodo Hospital

Abstract

Introduction: Poor hospital building environment quality is due to presence of potential sources of airborne microbial and may lead to HAIs (Hospital Acquired Infections). The research aimed to find out the relationship between the Bacillus sp. and Enterobacter sp. in the air with HAIs incident potential. Material and Method: This research was conducted in Dr. Wahidin Sudirohusodo hospital. This was an analytic observational research with the cross-sectional study design. Samples taken were human samples based on the criteria of the research as many as 61 patients, and the environmental samples were as many as 8 ICU rooms. The data were analyzed using the Chi-square test. Findings and Discussion: The research result indicates that the air quality related to the microbial pollution in the air in intensive care unit room does not qualify. The result of the microorganism culture and identification is found the HAIs causing bacteria namely Bacillus sp. and Enterobacter sp. Based on the statistic test, the value of p=0.014 (95% confidence intervals) is obtained, so there is the relationship between Bacillus sp. with HAIs incident potential. The Enterobacter sp. bacterium indicates the value of p=0.437 (95% confidence intervals), so there is not have the relationship between the Enterobacter sp. bacterium with HAIs incident potential. Conclusion: Bacillus in the air has the potential to cause HAIs in the ICU. Aspects of hygiene and sanitation appeared to be important factor in maintaining low microbial load in the air and further research is needed related to fungi and viruses in the air because of the potential source of HAIs.
