BACKGROUND: The occurrence of an outbreak of food-borne infectious disease requires a hospital to do extended role. There has been no report of an outbreak and an outbreak management of food-borne infectious diseases in a hospital. Therefore, this report of an outbreak and management of Shigellosis in the hospital would help others to manage further cases. METHODS: This was a descriptive study for an infection control program for food-borne infectious diseases in a hospital. RESULTS: There was a shigellosis outbreak at a university hospital in Seoul between December 3 and 30, 2001, Five hundred eighty four were affected, of which 81 cases were suspected and 86 cases were confirmed Shigella sonnei in fetal culture. The source of infection was identified as a lunch box or seaweed rolled rice that was contaminated and was supplied from the S-catering facility. The infection control team had developed the various strategies to control the outbreak and implemented them. The strategies included an epidemiology investigation, the removal of infection sources, medical treatment and isolation of patients, education and management of public relationship, environmental control, withdrawal of medical students' training, prevention and control of asymptomatic cases, intensive care unit strong financial support, analysis and management various data and the construction of cooperation and reporting system with the public health system CONCLUSION: This outbreak was controlled by effective team approach. The effective management of an outbreak of food-borne infectious diseases requires a systematic infection control, public relationship strategies for the reputation of the hospital, and the cooperation with a public health system.

Korean Journal of Nosocomial Infection Control.2004;9(1):27-36.

BACKGROUND: The aim of this study was to evaluate the sensitivity of a clinicians' self-report method for the detection of nosocomial infections (NIs) in comparison with a total surveillance method in a neonatal intensive care unit (NICU). METHODS: Two surveillance methods were concurrently performed in the NICU of a university hospital during 5 months in 2003. Clinicians' self-report surveillance (CSRS) was based on the retrospective verification of monthly reports of positive bacteriologic results by NICU clinicians. Total surveillance (TS) was done prospectively by an infection control nurse based on chart review and laboratory data. RESULTS: One hundred fifty nine patients accounting to 2759 patient-days were included in the study. Twenty-seven NIs among 26 patients were identified by TS. The sensitivity of CSRS compared to TS was 14.8% (4 of 27 NIs). The specificity was 98.5% (131 of 133 non-NIs). Kappa measures of agreement were -0.309. CONCLUSIONS: Our results confirm that the retrospective review of charts and laboratory data by clinicians lacks sensitivity and agreement for the surveillance of nosocomial infections.

Korean Journal of Nosocomial Infection Control.2004;9(1):17-25.

BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is highly prevalent in hospitals in Korea. The overall rate of MRSA in hospitals in Korea was estimated over 60%. Recently hospital infections caused by MRSA are getting increased and problematic in Korea, Our hospital Seoul Paik Hospital, has been trying to solve this problem. We had not applied exact methods for hospital infection control. Therefore, we adapted strict methods under the control of hospital infection control committee (HICC) and assessed the effectiveness of these methods. METHODS: Every month, the number of MRSA isolates was collected and analyzed; the results of the analysis were reported to every ward. All wards were supplied with Microshild(R) (Johnson & Johnson, Australia), Clean N' Fresh(R) (Carroll, USA), and standard paper towels. Health care workers were regularly educated for hospital infection control. The use of antibiotics was controlled by the HICC. We compared MRSA isolation rate between before and after applying the strict infection control methods under the regulation of HICC. Mann-Whitney U test, one-way ANOVA, and Chi-square test were used for statistical analysis of the results. RESULTS: After restricting the uses of antibiotics, glycopeptides and carbapenems were prescribed 15% less (20.3 vs 17.3 DDD /1000 patient-days) and 35% less (9.3 vs 6.0 DDD /1000 patient-days) respectively, compared to before restricting antibiotics. Methicillin resistance rate was decreased from 78% to 69% compared to before the methods(p=0.02). The isolation rate of MRSA was reduced by 31-42% from 2.33 to 1.35-1.60/1000 patient-days compared to before adapting strict infection control methods (p=0.04-0.07). CONCLUSION: This study showed that applying the strict infection control methods in the hospital can be effective to reduce the isolation rate of MRSA.

Investigation of Immune Status to Rubella Virus and Rubella Vaccination in Hospital Employees for Nosocomial Infection Control.

Tae Youn CHOI ; Won Bae KIM

Korean Journal of Nosocomial Infection Control.1997;2(2):97-103.

BACKGROUND: The risk of rubella infection is higher among hospital employees than others because of more exposure to rubella viruses. Because rubella infection during pregnancy can cause congenital rubella syndrome, special preventive measures should be taken for female employees in the hospital. METHODS: 309 employees in Soonchunhyang Kumi Hospital, aged from 18 to 45 years old, were included this study. Rubella IgG antibody was detected by the method of MEIA (microparticle enzyme immunoassay). And non-immunized employees were received by Wister RA 27/3 rubella vaccination and rechecked rubella antibody titers at 2 months later after vaccination. RESULTS: Among 309 subjects, 276(89.3%) were positive for rubella IgG antibody. The overall mean titer of rubella antibody was 72 IU/mL (SD: 67 IU/mL). The rubella antibody in titer decreased gradually with aging. The seroconversion rate after vaccination was 100%(28/28). CONCLUSIONS: The authors recommend that the employees susceptible to rubella or all employees in the hospital should be vaccinated for preventing rubella.

Korean Journal of Nosocomial Infection Control.1998;3(1):49-55.

BACKGROUND: The incidence of fungal urinary tract infections has increased in the immunocompromized patients. We analyzed urine culture results of St. Mary's Hospital during 28 month period between October 1993 and January 1996 to evaluate the frequency of yeast isolates and to survey the distribution of departments from where yeasts isolated. METHODS: We performed a retrospective analysis of urine culture results. Yeasts were identified by the examination of germ tube production in human serum at 37degrees C and API2OC (BioMerieux, France) yeast strip. RESULT: A total of 1,387 urine cultures were reviewed, of which 164 (11.8%) were isolated as fungi. Candida albicans occurred in 36.5% of the total yeast isolates, C. tropicalis in 35.3%, C. glabrata in 10.9% and Trichosporon beigelii in 0.6%. The incidence of urinary fungal infection increased in 1995 (13.0%) than 1994 (9.1%) (P=0.047). Fifty two percents (85/164) of urinary fungi were isolated from patients in Neurosurgery (NS), where isolation of C. tropicalis was significantly more increased than other departments. In four patients, candiduria progressed to candidemia, which were caused by C. albicans (three patients) and C. glabrata (1 patient). CONCLUSIONS: The isolation rate of yeast species was different in NS and non-NS department. The frequency of isolation of C. albicans increased in non-NS department than NS department, while the frequency of isolation of C. tropicalis increased in NS department than non-NS department. The most common organism was C. albicans and department was Neurosurgery.

Korean Journal of Nosocomial Infection Control.1998;3(1):41-47.

BACKGROUND: In the United States, the Centers for Disease Control and Prevention recorded a 20-fold increase in the incidence of vancomycin-resistant enterococci (VRE) associated with nosocomial infections between 1989 and 1991. Although VRE has been reported in Korea since 1992, infections caused by these organisms are still extremely rare in Pusan, Korea. Therefore, a point prevalence culture survey was carried out to investigate the prevalence of intestinal colonization with VRE among patients admitted to Kosin Medical Center, which can predict the appearance of clinical infections with VRE. METHODS: Between July 1997 and August 1997, stool specimens were obtained from 303 patients. Specimens were placed in bile esculin azide broth containing vancomycin (64 microgram/mL) and aatreonam (60 microgram/mL). Cultures were done for 48 hours at 37degrees C, and turbid solutions were subcultured on blood agar. Minimal inhibitory concentrations (MIC) of vancomycin and teicoplanin to Enterococcus isolates were determined by Etest on Mueller-Hinton agar. For amplification of the vanA, vanB, and vanC genes, polymerase chain reactions were performed. RESULTS: VRE isolates were isolated from 6 of the patients (2%). Four of them were identified as E. faecium, and 1 was identified as E. avium, and 1 was identified as Enterococcus spp. All of them were highly resistant to vancomycin (MICs >256 microgram/mL), and they were also resistant to teicoplanin (MICs 32-->256 microgram/mL). All of 6 VRE strains carried vanA gene. CONCLUSION: The colonization of VRE was not infrequent among the patients of a university hospital in Pusan, Korea. Moreover, a large proportion of the colonizing VRE was revealed Enterococcus faecium with vanA gene, which implies quite a possibility of a sudden rising of infections by this organism in the near future. So we propose that the vancomycin susceptibility test should be done for every enterococcal isolate from clinical specimens and the intestinal colonization rate of VRE should be closely monitored at regular intervals for the purpose of surveillance 50 that proper establishment of plans for the prevention of this troublesome pathogen's spread can be promptly made.
