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 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.

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.

Purpose: This study was conducted to identify factors influencing compliance of multidrug-resistant organism infection control in intensive care units (ICU) nurses. Methods: Data were collected from 254 ICU nurses who were working at 6 general and advanced general hospitals in D city and G Province. Results: 77.2% and 84.4% of the subjects correctly answered to questions about Methicillin-Resistant Staphylococcus Aureus (MRSA) and Vancomycin-Resistant Enterococcus (VRE), respectively. The scores of MRSA infection control compliance and VRE infection control compliance were 3.41 and 3.43, respectively. The factors influencing MRSA infection control compliance were empowerment, environmental safety recognition, and education satisfaction, which explained 30% of MRSA infection control compliance. The factors significantly related to VRE infection control compliance were empowerment, hospital types, environmental safety recognition, number of education sessions, and neonatal ICU, which explained 37% of VRE infection control compliance. Conclusion: It is necessary to develop efficient educational programs for infection control including educational contents to improve empowerment and environmental safety recognition of nurses. Furthermore, administrative support for those infection control programs is also necessary.

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: 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.

Methicillin-Resistant Staphylococcus aureus (MRSA) strains are resistant to a wide range of antibiotics and are a major cause of nosocomial infections. Accurate and rapid typing of MRSA is needed to implement effective infection control measures. Arbitrarily Primed PCR (AP-PCR) is a very useful method in rapid typing. AP-PCR is not necessary information about target DNA sequence because this is basically DNA amplification and could be useful in epidemiological typing by classified band pattern. In this study, MRSA were isolated and identified from ICU, Neu, IM and Ped environments and investigated molecular typing by AP-PCR. Ped, the MRSA pattern determines the la, IIa type, 1M is Ib type, Neu is IIa type and ICU determines the IIa, lIb types. All MRSA in this study were typeable by AP-PCR, which was easy to perform and reproduce with evidence of MRSA for purposes of nosocomial infection control.

Objectives : The purpose of this study was to survey the awareness of methicillin -resistant Staphylococcus aureus(MRSA) among dental hygiene students in Yeungnam South Korea. Also the knowledge of infection control and infection diseases was surveyed. Methods : The subjects in this study were 213 dental hygiene students in three different colleges in Yeungnam. This study was conducted by using the self-reported questionnaire. Results : In the first, most of the students(86.9%) did not know about MRSA and 85.7% of them got the information in the college. Secondly, the awareness of infectious disease according to infection control education didn't have statistically significant difference(p>0.05). In the third, the infection control attitude level that the gowns should be changed after the treatment of infectious patients was scored lower than the others questions. on the other hand, the level of 'The use of high vacuum suction', 'The change of wet mask', 'The history taking of infectious disease' was scored higher. Finally, the attitude level according to grade and clinical training had statistically significant difference(p<0.05). But the infection control education had not affected significantly(p>0.05). Conclusions : Despite the infection control education and clinical training, the awareness was found insufficient in infectious diseases and MRSA. Therefore, it should be strengthen that the dental hygiene students were more educated about infection control at college course before clinical training, and especially the danger of MRSA was more.

The purpose of this study was to identify the effects of bed baths with 2% chlorhexidine on the incidence of Methicillin-resistant Staphylococcus aureus (MRSA) and blood stream infection (BSI) and to suggest guidelines on the therapeutic bed baths using skin cleaner. This study was designed to compare the incidence of MRSA and BSI of the experimental group(n=188) who received the bed baths with 2% chlorhexidine with the incidence of MRSA and BSI of the control group(n=199) who received the existing bed baths with soap and skin cleaner. A research design used in the study was a randomized control group posttest-only design. The experimental group had 6.7% decrease in MRSA acquisition than the control group (7.4% vs 14.1%, p=.036). The experimental group was decreased in the incidence density of MRSA than the control group (9.32 cases per 1,000 patient-days at risk of experimental group vs 15.44 cases per 1,000 patient-days at risk of control group; p=.099). The experimental group had 4.5% decrease in the rate of BSI than the control group (0.5% vs 5.0%, p=.011). The experimental group was decreased in the incidence density of BSI than the control group (0.67 cases per 1,000 patient-days at risk of experimental group vs 5.52 cases per 1,000 patient-days at risk of control group; p=.052). These finding indicated that bed baths with 2% chlorhexidine is an effective nursing intervention to decrease the incidence of MRSA and BSI.
