Burkholderia cepacia, a widespread gram-negative environmental bacillus associated with nosocomial infection, is considered to be of relatively low virulence and rarely to cause invasive disease in immunocompromised patients. Nosocomial infections resulting from the use of contaminted medication, antiseptics and instruments have also been reported in otherwise healthy hosts. We experienced two cases of B. cepacia sepsis in 10 year-old male who was medicated with the anticancer drugs for the treatment of acute lymphoblastic leukemia(ALL) and in 15 day-old newborn who was examined with voiding vesicourethrography(VCUG) for the evaluation of congenital hydronephrosis. The organism isolated from serial blood culture in ALL patient and from serial blood culture and urine culture in newborn examined with VCUG. The former ALL patient improved after antibacterial medication of imipenem and the latter newborn improved after treatment with imipenem and trimethoprim-sulfamethoxazole.

Purpose: The study was investigated to identify the relationship between nursing workload and aseptic technique performance by clinical nurses, and to decrease the incidence rate of nosocomial infection. Methods: Participants (N=283) were recruited in B city from April to June 2007. The data were collected by a structured questionnaire and analyzed with descriptive statistics, t-test, ANOVA and Pearson's correlation coefficient. Results: Nursing workload was rated 9.85 out of a total score of 15. The level of aseptic technique performance as the basis for insertion of a Foley catheter was 42.72 out of a total score of 50, and as basis for insertion of intravenous catheter for fluid therapy was 40.11 out of a total score of 55. There was not a significant relationship between aseptic technique performance and nursing workload. There was a significant positive relationship between the aseptic technique performance in insertion of Foley catheter and that of intravenous catheter for fluid therapy (r=.279, p<.001). Conclusions: Attention to asepsis by nurses is crucial in nosocomial infection-related clinical nursing skills.

A 57-year old man who was admitted to an emergency room of a tertiary hospital with hemoptysis developed malarial fever 19 days later and then died from severe falciparum malaria 2 days later. He had not traveled outside of Korea for over 30 years. Through intensive interviews and epidemiological surveys, we found that a foreign patient with a recent history of travel to Africa was transferred to the same hospital with severe falciparum malaria. We confirmed through molecular genotyping of the MSP-1 gene that Plasmodium falciparum genotypes of the 2 patients were identical. It is suggested that a breach of standard infection control precautions resulted in this P. falciparum transmission between 2 patients in a hospital environment. This is the first report of a nosocomial transmission of falciparum malaria in Korea.

Acinetobacter baumannii strains are emerging pathogens of the nosocomial infection with an increasing frequency in recent years. The therapeutic difficulty due to the wide spread of multiple resistant strains was major problem in A. baumannii infection. It seems likely that high frequency of A. baumannii infection will be increasing epidemiological importance in the future. However, the current limited understanding of the epidemiology of A. baumannii infections is caused by lack of a rapid and practical method for the molecular characterization of A. baumannii strains. This study was undertaken to determine molecular types and genetic similarity among A. baumannii strains isolated from four hospitals by RAPD analysis. Eighty-five strains, including 40 from Chunnam University Hospital, 27 from Dankook University Hospital, 15 from Yonsei University Hospital, and 3 from Seonam University Hospital, were classified into three molecular types. Molecular type II was the most common pattern and included 72 strains. All strains from Dankook University Hospital and 40 strains from Chunnam University Hospital belonged to molecular type I or II. A. baumannii strains form Yonsei University Hospital were very distant similarity values. The range of genetic similarity values among 85 strains of A. baumannii was 0.26 to 1.00. Although phenotypes including biotype and antimicrobial resistance pattern of A. baumannii strains were same or very similar to each other, their RAPD patterns were quite different. Typing with phenotypes was found to be less reliable than molecular typing by RAPD analysis. These results suggest that RAPD analysis provides rapid and simple typing method of A. baumannii strains for epidemiological studies. This work is the first epidemiological report of A. baumannii infections in Korea and it is hoped that results of this work may contribute to a better understanding of the clinical importance and epidemiology of A. baumannii strains.

This study was conducted to identify the degrees of awareness and performance of hospital infection control of early stage nurses working in medium and small sized hospitals. This survey was conducted for 15 days from Sep. 15 to Sep. 30, 2017. Data were then analyzed by SPSS Win 22.0 to determine the mean and SD, as well as to conduct t-tests, ANOVA, and Scheffe's test. The result were as follows: 1. There were significant differences in awareness of hospital infection according to urinary tract infection, respiratory infection, and disinfection of contaminated goods managements with age. 2. There were significant differences in performance of hospital infection according to hand washing (working department), fluid therapy (education need p<0.001), urinary tract (position), and respiratory infection management (position p<0.001). 3. The mean score of awareness and performance regarding hospital infection were significantly different (all items p<0.001). According to these results, systematic education for improving awareness and performance regarding hospital infection control by nursing staff in medium and small sized in hospitals should be conducted. In addition, organizational efforts to increase the number of early stage nurses and improve the usability of personal infection control devices should be encouraged.

Objectives: To evaluate the occurrence of patient adverse events in Korean hospitals as perceived by nurses and examine the correlation between patient adverse events with the nurse practice environment at nurse and hospital level. Methods: In total, 3096 nurses working in 60 general inpatient hospital units were included. A two-level logistic regression analysis was performed. Results: At the hospital level, patient adverse events included patient falls (60.5%), nosocomial infections (51.7%), pressure sores (42.6%) and medication errors (33.3%). Among the hospital-level explanatory variables associated with the nursing practice environment, 'physician-nurse relationship' correlated with medication errors while 'education for improving quality of care' affected patient falls. Conclusions: The doctor-nurse relationship and access to education that can improve the quality of care at the hospital level may help decrease the occurrence of patient adverse events.

A retrospective double blind study comparing 7 day with 2 day regimen of antibiotic prophylaxis was conducted among 200 patients undergoing open heart surgery. No case of endocarditis and wound infection occurred. Pneumonia developed in 5 cases of the 7 day and 1 case of the 2 day group. Urinary tract infection without clinical significance developed in 1 case of the 7 day and 3 cases of the 2 day group. Bacteremia developed in 2 cases of the 7 day and 1 case of the 2 day group. We concluded as follows: l. Administration of antibiotics for 2 days appears to be without substantial risk of infection comparing long term 7 day regimen. 2. 7 days of antibiotics may actually increase the risk of serious infection such as nosocomial pneumonia, and predispose to the development of infections with fungi or antibiotic resistant bacteria. 3. 2 days of prophylaxis is more beneficial than long term 7 day regimen for example economically.

Purpose : This study was performed to determine the clinical and epidemiologic characteristics of nosocomial rotavirus gastroenteritis. Methods : We retrospectively analyzed 628 medical records of patients with rotavirus gastroenteritis between 2001 and 2005. The patients were divided into two groups (the community-acquired group [528 cases] and the nosocomial group [100 cases]. The epidemiologic and clinical indices between the groups were analysed. For clinical comparison, 100 agematched cases were selected from the community-acquired group. Results : The male-to-female ratio was similar (1.4:1 vs. 1.5:1), but the mean age was lower in the nosocomial group compared to the community-acquired group (21.9${\pm}$15.5 months vs. 16.6${\pm}$10.3 months, P <0.001). The patterns of age distribution, annual frequency, and seasonal distribution were similar in both groups. The proportions of nosocomial cases in each year ranged from 9.8% to 22.4% of annual rotaviral infections, and these were not proportional to annual cases. The duration of fever appeared more prominent in the nosocomial group, and the severity of diarrhea was not different between the groups. The cases with a BUN >20 mg/dL were more in the community-acquired group (16% vs. 4%, P=0.01). Conclusion : The clinical and epidemiologic charateristics of nosocomial rotavirus gastroenteritis were similar and correlated to those of the community-acquired gastroenteritis.

Purpose: Burkholderia cepacia is an aerobic, glucose-non-fermenting, gram-negative bacillus that mainly affects immunocompromised and hospitalized patients. Burkholderia cepacia has high levels of resistance to many antimicrobial agents, and therapeutic options are limited. The authors sought to analyze the incidence, clinical manifestation, risk factors, antimicrobial sensitivity and outcomes of B. cepacia urinary tract infection (UTI) in pediatric patients. Methods: Pediatric patients with urine culture-proven B. cepacia UTI between January 2000 and December 2014 at Samsung Medical Center, a tertiary referral hospital in Seoul, Republic of Korea, were included in a retrospective analysis of medical records. Results: Over 14 years, 14 patients (male-to-female ratio of 1:1) were diagnosed with B. cepacia UTI. Of 14 patients with UTI, 11 patients were admitted to the intensive care unit, and a bladder catheter was present in 9 patients when urine culture was positive for B. cepacia. Patients had multiple predisposing factors for UTI, including double-J catheter insertion (14.2%), vesico-ureteral reflux (28.6%), congenital heart disease (28.6%), or malignancy (21.4%). Burkholderia cepacia isolates were sensitive to piperacillin-tazobactam and sulfamethoxazole-trimethoprim, and resistant to amikacin and colistin. Treatment with parenteral or oral antimicrobial agents including piperacillin-tazobactam, ceftazidime, meropenem, and sulfamethoxazole-trimethoprim resulted in complete recovery from UTI. Conclusion: Burkholderia cepacia may be a causative pathogen for nosocomial UTI in pediatric patients with predisposing factors, and appropriate selection of antimicrobial therapy is necessary because of high levels of resistance to empirical therapy, including aminoglycosides.

Purpose: To identify risk factors for surgical site infections in patients undergoing general surgery, to analyze the prolonged hospital stay and extra cost for antibiotics, and to provide basic data for control of surgical site infections. Method: Surgical site infection was defined using the definition of the CDC and the data were analyzed by $x^2$-test and unpaired t-test. Results: The prevalence of surgical site infections was 9.7%, and it was related to wound class, duration of operation, number of operations, whether the operation was an emergency, trauma, drains, preoperative stays, presence of remote infection during operative period, and previous history of recent surgery. The mean duration for post-operative stay when a surgical site infection occurred was 9.5 days and in 56.9 % of the patients the surgical site infection appeared 7 days after the operation. Post-operative stays for infected patients were 20.3 days longer than that of uninfected patients. The mean cost of antibiotics for infected patients was higher than that for uninfected patients by 561,067 won per person. Conclusion: Surgical site infection results in an increased length of stay and extra-cost, thus, hospitals need to create strategies to reduce nosocomial infections through effective infection surveillance and by considering factors related to surgical site infections.
