This study was conducted on nursing staff at care hospitals to confirm the mediating effect of health beliefs between the knowledge of nosocomial infections management and the execution of nosocomial infections management. This study was carried out on nurses and assistant nurses working at five care hospitals located in Busan, and finally 212 questionnaires were analyzed through SPSS 25.0 and SPSS Procee Macro. The results of the study showed that knowledge of nosocomial infections management is significant in the execution of nosocomial infections management(B=2.90, p<.001), and the influence of health beliefs was shown to be significant as well(B=.52, p<.001). Knowledge of nosocomial infections management has a direct effect on the execution of nosocomial infections management, and was also shown to have an indirect effect on the execution of nosocomial infections management through health beliefs, confirming partial mediating effects. This study is significant in that it provides the baseline data necessary for the effective execution of nosocomial infections management of nursing organizations in care hospitals by verifying the mediating effects of health beliefs in terms of the effects of knowledge of nosocomial infections management perceived by nurses and assistant nurses working in care hospitals on the execution of nosocomial infections management.

Studies on the concentration of airborne microorganisms in human medicine as a part of a study on the nosocomial infections have been conducted properly, but in veterinary medicine, there has been rarely performed in Korea to the best of study's knowledge. The purpose of this study was to evaluate the distribution of airborne microorganisms and to identify their species in different places in the animal hospital to alert the necessity of thorough cleanliness management. This study evaluated the concentrations of airborne bacteria and fungi in hospital areas, such as patient waiting room, internal medicine ward, surgical ward and radiological diagnostic ward. The concentration of bacteria and fungi was significantly lower (p < 0.05) in two operating rooms and higher in the patient waiting room. The dominant species of bacteria were Micrococcus spp., Staphylococcus spp., and fungi were Penicillium spp., Dermatophyte mold. Animal hospitals need to perform proper procedures for disinfection, sterilization, and environmental cleaning as well as appropriate employee training and monitoring in order to the maximum prevention of the risk of nosocomial and surgical infections.

Background/Aims: Improved knowledge of local epidemiology and predicting risk factors of multidrug-resistant (MDR) bacteria are required to optimize the management of infections. This study examined local epidemiology and antibiotic resistance patterns of liver cirrhosis (LC) patients and evaluated the predictors of MDR bacteremia in Korea. Methods: This was a retrospective study including 140 LC patients diagnosed with bacteremia between January 2017 and December 2022. Local epidemiology and antibiotic resistance patterns and the determinants of MDR bacteremia were analyzed using logistic regression analysis. Results: The most frequently isolated bacteria, from the bloodstream, were Escherichia coli (n = 45, 31.7%) and Klebsiella spp. (n = 35, 24.6%). Thirty-four isolates (23.9%) were MDR, and extended-spectrum beta-lactamase E. coli (52.9%) and methicillin-resistant Staphylococcus aureus (17.6%) were the most commonly isolated MDR bacteria. When Enterococcus spp. were cultured, the majority were MDR (MDR 83.3% vs. 16.7%, p = 0.003), particularly vancomycin-susceptible Enterococcus faecium. Antibiotics administration within 30 days and/or nosocomial infection was a significant predictor of MDR bacteremia (OR: 3.40, 95% CI: 1.24-9.27, p = 0.02). MDR bacteremia was not predicted by sepsis predictors, such as positive systemic inflammatory response syndrome (SIRS) or quick Sequential Organ Failure Assessment (qSOFA). Conclusions: More than 70% of strains that can be treated with a third-generation cephalosporin have been cultured. In cirrhotic patients, antibiotic administration within 30 days and/or nosocomial infection are predictors of MDR bacteremia; therefore, empirical administration of broad-spectrum antibiotics should be considered when these risk factors are present.
