Purpose: To assess the effect of handwashing improving program and MRSA carrier detection program on MRSA(methicillin resistant Staphylococcus aureus) infection rate in a intensive care unit. Method: The intervention was Nosocomial Infection(NI) control program consisted of hand washing improving program and identification and treatment of MRSA carrier. Data on the NI and MRSA infections were collected by an infection control nurse based on the definition of CDC. MRSA infection rates were calculated by the number of MRSA infection per 100 admissions or 1,000 patients-days. The difference of MRSA infection rates between pre and post intervention was tested by Chi-square at =.05. Result: MRSA infection rates 3.0% or 3.2 per 1,000 patient-days at the pre, 4.6% or 3.7 per 1,000 patient-days at the post, and the differences were not statistically significant (p=.411, p=.769 respectively). Conclusion: The handwashing improving program and MRSA carrier detection program was not effective in reducing the Nosocomial Infection(NI) or MRSA infection rates. It is recommended further studies with a longer intervention and follow-up period.

Purpose: The effectiveness of an infection control program is important to hospital quality improvement and decreases of mortality rate and prevalence. Methicillin resistant Staphylococcus aureus (MRSA) is the most common pathogen causing nosocomial infection. The aim of the study was to identify the most important risk factors for acquiring an MRSA, to evaluate the MRSA incidence rates after the nursing intervention in Neurosurgery intensive care unit (ICU). Methods: Clinical data were collected prospectively from December 2008 until July 2009 in Neurosurgery ICU. The patients were divided into preintervention and postintervention groups. An infection was defined as an MRSA if it occurred 48 hr after admission to the Unit. Infection control program including hand washing, education of health care workers about MRSA, standard precaution and contact isolation of patients were applied for three month. Results: A total of 85 patients were included in the study. Forty-five patients of S. aurerus were detected. Among 45 of S. aurerus, MRSA were isolated from 38 patients. The incidence MRSA rate of postintervention group was 26.9% while incidence MRSA rate of preintervention group was 66.7%. In total, The incidence MRSA rate was 44.7%. The incidence of MRSA have decreased in the postintervention as compared with the preintervention group. Conclusion: The infection control program for MRSA was effective to decrease the MRSA isolation rate. The health care workers regular hand washing, education of nosocomial infection control is important enough to be emphasized.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) infection is a severe and life-threatening disease in patients with community-onset (CO) pneumonia. However, the current guidelines lack specificity for a screening test for MRSA infection. Methods: This study was retrospectively conducted in elderly patients aged ${\geq}65years$, who had contracted CO-pneumonia during hospitalization at the Jeju National University Hospital, between January 2012 and December 2014. We analyzed the risk factors of MRSA in these patients and developed a scoring system to predict MRSA infection. Results: A total of 762 patients were enrolled in this study, including 19 (2.4%) with MRSA infection. Healthcare-associated pneumonia (HCAP) showed more frequent MRSA infection compared to community-acquired pneumonia (4.4% vs. 1.5%, respectively; p=0.016). In a multivariate logistic regression analysis, admissions during the influenza season (odds ratio [OR], 2.896; 95% confidence interval [CI], 1.022-8.202; p=0.045), chronic kidney disease (OR, 3.555; 95% CI, 1.157-10.926; p=0.027), and intensive care unit admission (OR, 3.385; 95% CI, 1.035-11.075; p=0.044) were identified as predictive factors for MRSA infection. However, the presence of HCAP was not significantly associated with MRSA infection (OR, 1.991; 95% CI, 0.720-5.505; p=0.185). The scoring system consisted of three variables based on the multivariate analysis, and showed moderately accurate diagnostic prediction (area under curve, 0.790; 95% CI, 0.680-0.899; p<0.001). Conclusion: MRSA infection would be considered in elderly CO-pneumonia patients, with three risk factors identified herein. When managing elderly patients with pneumonia, clinicians might keep in mind that these risk factors are associated with MRSA infection, which may help in selecting appropriate antibiotics.

Methicillin-resistant Staphylococcus aureus (MRSA), a leading cause of nosocomial infections, has been increasingly recognized in communities of the United States. This article will review the clinical spectrum and treatment of MRSA infections in children in the context of recent epidemiological changes of MRSA infections. In general, community-associated (CA) MRSA most frequently causes skin and soft tissue infections and has an increased association with invasive infections, particularly pneumonia and musculoskeletal infections. Hospital-associated (HA) MRSA strains tend to be associated with bloodstream infections, pneumonia, and surgical site infections. Different from the United States, CA-MRSA infections are not common in Korea (only 5.9%); however, there are some CA-MRSA clones that are different from HA-MRSA clones in Korea and from CA-MRSA clones in other countries. The treatment of MRSA infections should be guided by antimicrobial susceptibility testing, the site of infection, and the infection severity. Vancomycin is the treatment of choice for invasive MRSA infections. Other agents such as trimethoprim-sulfamethoxazole, clindamycin, linezolid, quinupristin-dalfopristin, and daptomycin have been used for some conditions.

Methicillin resistant Staphylococcus aureus (MRSA) is one of the most common nosocomial pathogens. Many hospitals are facing the problems which they have to use expensive antibiotics and suffer from long term hospital study of patients due to MRSA. This study is to survey MRSA nasal colonization of patients and doctors, and to investigate the mode of transmission of MRSA by pulsed field gel electrophoresis (PFGE) and then use these data to prevent further spread of cross infection and reduce nosocomial infection. Subjects of this study were 201 patients with MRSA infection at an university hospital in Busan from Sept. 1997 to Aug. 1998. Bacterial genotypes of MRSA strains isolated from nares and wound of patients (14 cases) and nares of doctors (8 cases) were analyzed by PFGE. Nasal cultures of 20 I patients for detecting nasal colonization of MRSA were performed and incidence rate of nasal colonization was 40％ (80/201). Among 201 patients MRSA were acquired from hospital in 140 (70％) patients and were acquired from community 61 (30％) patients. Among 14 pairs of MRSA from colonized or infected sites and anterior nares, DNA patterns of 10 pairs (71.4％) were equal. 86％ (12/14) MRSA strains isolated from patients and 12.5％ (1/8) MRSA strains isolated from doctors show same pattern. DNA patterns were changed in some doctors after nasal oint. Treatment. It could be inferred that the most sources of MRSA in hospital are the endemically existing MRSA. Therefore, we believe that it would be necessary to control MRSA nasal colonization of the patients and the related medical teams to reduce the medical cost and to improve the efficacy of medical cares.

Purpose: The purpose of this study was to describe nurses' recognition of, and practice level in management of general nosocomial infections, and methicillin resistant staphylococcus aureus (MRSA) and vancomycin resistant enterococci (VRE) infections. Method: A self-administered questionnaire was used to collect data. Data were collected on June, 2003 from 190 nurses in one university affiliated hospital located in Suwon. Result: The mean score for nurses' recognition of general nosocomial infection control was 3.57, MRSA control was 3.54, and VRE control was 3.86. The mean score on practice for control of general nosocomial infection was 3.19, for MRSA control, 3.20, and for VRE control, 3.63. There were statistically significant relationships between the recognition level and practice level for general nosocomial, MRSA, and VRE infection control. According to the general characteristics of the nurses, the mean scores for both recognition and practice were higher for those nurses who had had infection control education, for those who had worked longer in nursing, and for those who worked in the ICU. Conclusion: It is suggested that appropriate hospital infection control programs should be developed through continuous education and practice to improve nurses' level of the practice in general infection control, and especially in MRSA and VRE infection control.

Nosocomial infection and community-acquired infection with Staphylococcus aureus, especially methicillin-resistant S. aureus (MRSA), has become a strong concern in human body sites and related effects. The aim of this study is investigate the isolation rate of MRSA from nasal cavity inferior regions and cellular phones to assess the risk factor of nosocomial infection and community-acquired infection. 34.7% and 37.2% isolates were MRSA from the nasal cavity inferior regions and cellular phones according to a Mannitol salt agar (added oxacillin $6{\mu}g/mL$) culture and PCR according to S. aureus specific 16S rRNA and mecA primers. Thus, the distribution of S. aureus and the isolation rate of MRSA represent a very high risk factor regards nosocomial infection and community-acquired infection.

Purpose: Methicillin-Resistant-Staphylococcus aureus(MRSA) has been increasingly recognized as a cause of nosocomial infection. MRSA is hardly-controllable organism among the pathogen of nosocomial infection, because it is resistant to most antibiotics except vancomycin, and local treatment with most antiseptics are not effective to eradicate MRSA from the infection. The effectiveness of Vacuum-Assisted-Closure(VAC) was reported widely. we tried to modify original VAC. We tried VAC dressing on MRSA infected wound to evaluate whether or not the VAC is effective to eradicate MRSA which existed in the open wound. Methods: From September 2003 to December 2003, 24 patients admitted to the plastic and reconstructive surgery and orthopedic surgery, were studied. All patients were found to be positive in previous wound. Using clinical randomized study, 24 patients were divided into two groups: VAC dressing group and the $Betadine^{(R)}$ dressing group(control). During treatment, wound culture was done twice a week for evaluation of MRSA infection elimination. Results: The mean period that MRSA become not detected in all case was 17.1 days in VAC dressing group, and 25.8 days in control group, respectively. The p value was 0.013. The result reveals that the VAC dressing group is more effective to MRSA infection control. As a result, the VAC dressing was more effective in MRSA infected wound than conventional dressing. Conclusion: Through this study, we found objective result of VAC dressing. We hope that VAC dressing is more widely applied to fresh and infected wound.
