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.

Purpose: This study was designed to identify recognition and the performance level for nosocomial infections amongst student nurses and to provide data for preparing on efficient policy and control program for nosocomial infections. Method: 191 senior nursing student participated in this research from 5 nursing college which allowed data collection, in the city of Seoul. The questionnaire was composed of 73 items(likert scale) about eight areas; aseptic technique, disinfection, precaution, hand washing, urinary tract infection, respiratory infection, catheter related infection, and self care about nosocomial infections. Results: The mean score of recognition and performance level for management of nosocomial infection were 4.29 and 3.41 respectively. The mean score of the recognition level was significantly lower than the performance level in the eight areas. The mean score of both recognition and performance were highest in the area of disinfection. However, the mean score of recognition was lowest in the area of aseptic technique and the mean score of performance was lowest in the area of catheter related infections. The correlation of recognition and performance level was statistically significant. Conclusions: These research findings should be useful in promoting an intensive and continuous educational program on nosocomial infection for nursing students and to establish an efficient policy for preventing nosocomial infections.

This study was done to analyze the effects of a smear in the nasal cavity against nosocomial Infection. The smear used was mupirocin, and the study centered on infection which constitutes the majority of nosocomial infections called MRSA. The data were collected between March 23 1998 and June 31 of the same year in a university hospital in the Kyongi Province, and is made up of a experimental group of 14 patients who were given nasal cavity smears and a control group of 16 patients who were not given nasal cavity smears. The data were analyzed through frequency and the Chi-square tests and gave forth these results. 1. Of the experimental group 28.6% developed nosocomial infections while 62.5% of the control group developed infections. This difference was significant. 2. In the experimental group, all of the patients developed infections within the first week in the ICU, while 80% of the control group developed infections in the first week and 20% in the second week. The difference was not as marked here. 3. In the experimental group the DM group 66.7% contracted MRSA while 18.2% developed it in the non-DM group showing that the DM group had infection rate was 3.7 times higher than the non-DM groups. In the control group the DM group had a 100% infection rate while 50% of the non-DM group developed it. Overall the DM group's rate infection was 2.4 times higher than the non-DM group. 4. In the experimental group, 37.55% of the patients who had a tracheostomy developed it while 16.7% of the patients who did not have a tracheostomy developed infections. In the control group, 62.5% of the patients who had tracheostomy, and 37.5% of the patients who did not have tracheostomies developed infections. Those who had tracheostomies, and the control group had double the rate contracting infections. From these results we can see that nasal cavity smears are effective against nosocomial infections. In spite of the smears, patients with the diabetes mellitus had a high MRSA infection rate, which requires new alternative treatments.

Purpose :Rotavirus is one of the most important causes of nosocomial infections among children. The aim of this study is to determine the risk of nosocomial rotavirus infections and to evaluate the effectiveness of breast-feeding and probiotics in the prevention of nosocomial rotavirus infections. Methods : This study was carried out on admitted children without diarrhea between March 1, 2003 and February 29, 2004. Three hundred ninety patients aged 4 days to 13 years during this study were available. We examined the feces of all children for rotavirus by latex agglutination on admission, during hospital, and after discharge, to see whether they developed diarrhea or not. Results : Nosocomial rotavirus infections was significantly increased with children under 12 months of age(P=0.008). The monthly attack rate was great between December and March(P=0.046). Prolonged hospital stay was associated with an increased attack rate of nosocomial rotavirus infections (P=0.003). The risk of nosocomial rotavirus infections was not associated with the number of roommates and whether or not they were breast-fed or fed on probiotics. Conclusion : Nosocomial rotavirus infections are significantly more likely to occur in children under 12 months of age, admitted between December and March, and with prolonged hospital stays. Prompt identification and isolation of children with nosocomial rotavirus infections, even without diarrhea, may decrease rates of nosocomial rotavirus infections.

Purpose: This retrospective study was done to evaluate the status of nosocomial urinary tract infections and to determine the risk factors and transmission route of causal IRPA through molecular epidemiology. Method: Two hundred ninety-nine of 423 patients admitted to the internal medicine and surgery ICU at a university hospital incity B had a positiveurine culture. Twelve of the 299 patients who had a urinary tract infection had IRPA strains. The data was collected from November 1, 2004 to January 31, 2005. The following results were obtained after the data was analyzed using percentile and UPGMA. Result: The rate of nosocomial urinary tract infections in the ICU was 10.8%. Therewere 16.8 cases of infection based on the period of hospitalization. There were 16.9 cases of infection based on the use of a foley catheter. The rate of nosocomial urinary tract infection in the ICU and urinary tract infections related to IRPA were higher in patients with the following characteristics: men, old age, admission through the emergency room, longer than seven days admission, severity of admitting causes, disturbance of consciousness, hydration less than 300cc in 24hours, a long course of antibiotics, a long period of foley catheterization and perineal care. Most of the microorganisms that caused the urinary tract infection were gram negative bacilli, among which P. aeruginosa was found in 70 patients (18.5%) and IRPA in 12 (4.0%). Among the 12 IRPA strains that were tested with PFGE, eight showed a dice coefficient higher than 80%, suggesting a genetic relationship. They were related with the period of hospitalization in the same ICU. These patients all received direct care for a urinary tract infection. Conclusion: Through these results, IRPA can be consideredas a contributing factors to urinary tract infections thus, active preventative measures are needed by the medical staff.

Nosocomial infections, commonly referred to as healthcare-associated infections, are illnesses that patients get while hospitalized and are typically either not yet manifest or may develop. One of the most prevalent nosocomial diseases in hospitalized patients is pneumonia, among the leading causes of mortality and morbidity. Viral, bacterial, and fungal pathogens cause pneumonia. More severe introductions commonly included Staphylococcus aureus, which is at the top of bacterial infections, per World Health Organization reports. The staphylococci, S. aureus, strain RMI-014804, mesophile, on-sporulating, and non-motile bacterium, was isolated from the sputum of a pulmonary patient in Pakistan. Many characteristics of S. aureus strain RMI-014804 have been revealed in this paper, with complete genome sequence and annotation. Our findings indicate that the genome is a single circular 2.82 Mbp long genome with 1,962 protein-coding genes, 15 rRNA, 49 tRNA, 62 pseudogenes, and a GC content of 28.76%. As a result of this genome sequencing analysis, researchers will fully understand the genetic and molecular basis of the virulence of the S. aureus bacteria, which could help prevent the spread of nosocomial infections like pneumonia. Genome analysis of this strain was necessary to identify the specific genes and molecular mechanisms that contribute to its pathogenicity, antibiotic resistance, and genetic diversity, allowing for a more in-depth investigation of its pathogenesis to develop new treatments and preventive measures against infections caused by this bacterium.

Purpose: Despite the recent increased number of nosocomial measles, the outbreak investigation reports are not usually standardized, thus posing unclear understanding of magnitude of its public health burden. We used the Outbreak Reports and Intervention Studies of Nosocomial Infection (ORION) statement, to compare nosocomial outbreaks and synthesize evidence to prevent hospital transmission of measles. Methods: A PubMed, Web of Science, Embase, Scopus, and Cochrane search in English, using the medical subject headings "measles," "nosocomial," "hospital," and "healthcare," was performed. We evaluated the quality of outbreak reports of nosocomial measles infection worldwide using the ORION statement findings and recommendations. Results: We reviewed 24 studies in accordance to the ORION statement. Measles transmission in healthcare settings is a significant burden on the morbidity, mortality, and economy of measles. The healthcare workers' booster vaccination guidelines should be monitored and enhanced during the post-elimination period of measles. The outcomes of infections must be explicit for outbreak reports. Conclusions: This study identified the epidemiological and clinical characteristics of nosocomial measles infections and provided strong evidence for infection control policies in hospitals.

Background: The prevalence of extended-spectrum ${\beta}$-lactamase (ESBL)-producing Escherichia coli is increasing rapidly worldwide. Treatment options for ESBL-producing E. coli are limited, and infections caused by this organism are associated with improper antibiotic use, a long hospital stay, and increased mortality. Thus, the assessment and early recognition of the risk factors of nosocomial infections due to ESBL-producing E. coli are important for the infection control and proper treatment. Methods: A case-control study was performed that included nosocomial episodes of ESBL-producing E. coli bacteremia at a tertiary care hospital from January 2004 to December 2007. For each case patient, three controls were randomly selected and data on predisposing factors were collected. Results: Fifty-five cases of nosocomial ESBL-producing E. coli bacteremia were studied. Carbapenem usage (OR: 11.3, 95% CI: 1.1-115.9, p=0.041), quinolone usage (OR: 4.5, 95% CI: 1.1-18.8, p=0.042), biliary obstructive disease (OR: 11.8, 95% CI: 3.0-46.7, p<0.001) and the APACHE II score (OR: 1.3, 95% CI: 1.2- 1.5, p<0.001) were analyzed as independent risk factors of nosocomial ESBL-producing E. coli bacteremia. Conclusion: Our results showed that physicians caring for patients with risk factors of nosocomial bacteremia should consider ESBL-producing E. coli as the causative organisms of the disease.
