BACKGROUND: This study tested the efficacy of 0.12% chlorhexidine gluconate for improving oral hygiene in intubated intensive care patients. METHODS: In a group of 57 ventilated patients, 29 received normal saline (NS) for oral hygiene, and 28 were treated with chlorhexidine gluconate (CHG). Data on oral bacterial colonization was collected for 11 months from October 2005 to August 2006. Tests of oral hygiene and oral microorganism culture were performed on the day of the ventilation, and repeated on days 4, 8, and 12. RESULTS: Oral hygiene was significantly improved in the CHG group compared to that in the NS group (P<.001). Further, all patients (100%) in the NS group tested positive for Staphylococcus aureus on the 12th day after the endotracheal intubation, whereas only 42.9% (P=0.026) of the CHG group were positive. The NS group also had higher isolation rates of Pseudomonas aeruginosa at 66.7% on the 8th day after intubation and 87.5% on the 12th day. At these same intervals, the CHG group had isolation rates of 29.4% (P=.028) and 14.3% (P=.010) respectively. CONCLUSION: The longer the period of endotracheal intubation, the more effective the 0.12% CHG treatment was for improved oral hygiene and reduction of S. aureus and P. aeruginosa colonization when compared to treatment with NS.

BACKGROUND: Over the past several years, Clostridium difficile has become a major healthcare-associated pathogen. Fecal bacteriotherapy has been reported as an effective intervention for treating recurrent C. difficile infection by restoring the normal intestinal microbiota. METHODS: Articles on fecal bacteriotherapy were collected through PubMed, CINAHL, Cochrane Library, and Web of Science databases using the keywords "Clostridium difficile," "feces," "fecal transplantation," "fecal microbiota transplantation," and "fecal bacteriotherapy." Using a systematic literature review, variables of interest from articles that met the inclusion criteria were extracted and summarized. RESULTS: Among 141 articles that were published in English from January 1, 2000 to August 31, 2012, 8 studies were selected for analysis after assessing the titles, abstracts, and full contents. Fecal bacteriotherapy procedures varied with respect to donor selection, screening, infusion route, and preparation of the suspension. Donors were mostly family members or relatives, and donor screening included tests for blood borne and stool pathogens. Selected infusion routes were colonoscopy (62.5%), nasogastric tube (25%), and enema (12.5%). The success rate was reported to be 73-100%. There was a lack of a standard procedure for fecal bacteriotherapy in all of the selected studies. CONCLUSION: Fecal bacteriotherapy is an effective intervention for combating C. difficile infection that has a high success rate and no adverse effects. This therapy would be helpful for infection control in hospital settings by facilitating early eradication of C. difficile infection.

BACKGROUND: This study aims to examine the knowledge of nursing and allied health-college students on cough etiquette and their actual compliance to it. METHODS: For data collection, a structured questionnaire was created and handed out to students from 3 colleges from November 9 to November 18, 2011. The questionnaires were distributed to 300 students, and responses from 253 students were used for data analysis. RESULTS: In total, 54.85% students provided correct answers to questions regarding their knowledge on cough etiquette. The compliance score was 34.39 (compliance rate: 61.41%). There was a positive association between knowledge of proper cough etiquette and compliance with those procedures. CONCLUSION: It can be concluded that college student's knowledge of cough etiquette is low, and subsequently that their compliance with the proper procedures of cough etiquette was low. Therefore, it is necessary to develop a program to build knowledge of proper cough etiquette amongst these students.

BACKGROUND: Compliance with hand hygiene protocols is one of the simplest ways to prevent healthcare-associated infections (HAIs). Hand hygiene is influenced by individual habits and beliefs, as well as by local organizational culture practices. This study was performed in order to increase the rate of compliance to hand hygiene through changes in the organizational culture. METHODS: From 2009 through 2011, this study was performed in a 2,000-bed tertiary-care university hospital with more than 6,000 employees. The program was implemented mainly by team activities, and the leadership and hand hygiene steering committee members supported them. Goals for planning, intervention, and evaluation of the compliance rate for hand hygiene were made annually in the hospital. RESULTS: The rate of compliance to hand hygiene increased significantly each year (43.8% in 2008, 75.3% in 2009, 80.7% in 2010, and 83.2% in 2011). The detection rate of vancomycin-resistant Enterococcus (VRE) and the incidence of healthcare-associated Staphylococcus aureus bacteremia decreased. CONCLUSION: The rate of compliance to hand hygiene was remarkably improved, and it continuously increased through systematic and continuous changes in the organizational culture. In addition, the detection rate of VRE and incidence of S. aureus bacteremia decreased. These results show that hand hygiene is an important factor for preventing HAIs.

Ochrobactrum anthropi, a rarely encountered organism in humans, is usually associated with infections in immunocompromised hosts and patients with indwelling catheters. We report a case of bacteremia associated with O. anthropi in a 80-year-old male with intrahepatic duct carcinoma. After insertion of biliary stent with endoscopic retrograde cholangiopancreatography, fever and neutrophilic leukocytosis developed in the patient. Blood cultures were performed three times, and O. anthropi was isolated from an aerobic bottle. Although the patient did not receive effective antibiotic treatment, fever and neutrophilic leukocytosis were improved.

BACKGROUND: The aim of this study was to evaluate the influence of an improved method of endotracheal suction on nosocomial pneumonia (NP) and tracheal colonization by Pseudomonas aeruginosa and Acinetobacter baumannii in intensive care units (ICUs). METHODS: The study was carried out in both the medical and surgical ICUs of a tertiary-care university hospital; 2,347 patients were admitted in the ICUs from January 2003 to December 2004. The method of endotracheal suction to remove secretions was improved by using a sterile, individually packed catheter and sterile fluid filled in a small container for a single use instead of sterile catheters and fluid packed or filled in large containers for a multiple use. Then, we compared the incidence of NP, the colonization rates of P. aeruginosa and A. baumanni in the respiratory tract, and their carbapenem resistance before and after the intervention. RESULTS: The incidence of NP (1,000 patient-day rate) was decreased from 4.08 to 2.46 in the SICU and from 1.4 to 0.8 in the MICU after the intervention, but the differences were not significant. The colonization rate by A. baumannii was decreased significantly from 35.7% to 4.6% in the SICU (P<0.001) and from 12.7% to 7.6% in the MICU (P<0.001). The colonization rate by P. aeruginosa was decreased significantly from 17.7% to 7.4% in the SICU (P<0.001), but not in the MICU. There was also a marked decrease in carbapenem resistance, 21% to 8% in P. aeruginosa and 70% to 16% in A. baumannii. CONCLUSION: Endotracheal suction with a sterile catheter and sterile fluid is important in preventing respiratory infections and colonization by P. aeruginosa and A. baumannii in the ICU.

BACKGROUND: Cost-benefit studies for hospital infection control and prevention (HICP) are often applied to improve the investment for infection control; however, an accurate cost measurement for HICP would be necessary before a cost benefit analysis and establishing a proper policy for HICP. The purpose of this study is to analyze the costs of HICP for the hospital in Korea. METHOD: The costs associated with HICP in the year 2004 were surveyed for 8 university-affiliated teaching hospitals in Seoul and Kyounggi province. The collected data included the costs for standard precaution materials including hand hygiene and personal protective equipments, hospital employee health service, maintenance of hospital facility and environmental control, and operating infection control office. RESULT: The average costs for HICP were estimated to be 785,115 won per one bed per year. Among the contributing factors to the total costs were the cost for patient isolation in private rooms (310,458 won), disinfectants (125,533), hand hygiene materials (99,007), maintenance of hospital environmental hygiene (90,773), operation of infection control office (65,811), personal protective equipment (58,099), and employee health care (35,434). CONCLUSION: We estimated the annual cost of HICP at a minimum of 96,723,000 won for a 100-bed hospital. This study contributes to establishing the basic and necessary data for a proper HICP compensation system by providing various HICP costs for the university hospital.

BACKGROUND: The purpose of this study was to survey the nasal colonization of methicillin-resistant Staphylococcus aureus (MRSA) among the patients admitted in a medical intensive care unit (MICU) and analyze risk factors associated with the colonization. METHODS: The study was carried out on patients admitted into the MICU in a 1,250-bed tertiary care university hospital from January through December 2006. Nasal surveillance cultures were obtained from patients within 24 hours of admission to the unit. Data were analyzed retrospectively by the review of medical records. RESULTS: A total of 312 patients were screened with active nasal cultures; 36 patients (11.6%) were positive for MRSA. Of these, 22 (7.1%) were positive in the nasal cultures only and 14 (4.5%) were positive in the cultures of other specimens (13, sputum; 1, joint fluid) in addition to the nasal swabs. Among the risk factors for MRSA nasal colonization were sex (man), route of admission (from other ICUs or wards), a history of ICU admission during the recent 12 months, and prolonged hospital days in ICU. CONCLUSION: MRSA nasal carrier rate was found higher in this study than in those reported in the literature. Most of the patients colonized with MRSA in the nostril were not colonized with the organism elsewhere in the body. Whether or not active surveillance for MRSA should be performed would depend on the nasal colonization rate of the patients at the time of admission to the ICU.

BACKGROUND: Catheter-related bloodstream infections (CR-BSIs) are common, costly, and potentially lethal. The purpose of this study was to ascertain the effect of maximal sterile barrier on CR-BSIs in intensive care units. METHODS: We monitored CR-BSIs in intensive care units of Sunlin Hospital in Pohang, before (September 2005 to May 2006) and after (June to December 2006) implementation of maximal sterile barrier. CR-BSIs were identified by using the definition of Centers for Disease Control and Prevention. RESULTS: During the intervention period, the proportion of conducting maximal sterile barrier was 84%. In the pre-intervention period, 10 episodes of CR-BSIs were recorded out of a total of 1,749 catheter-days, compared to 1 episode of CR-BSI out of a total of 1,277 catheter-days in the post-intervention period. The rate of CR-BSIs was significantly reduced from 5.72 to 0.57 per 1,000 catheter-days (P=0.03). CONCLUSION: Implementation of maximal sterile barrier resulted in a significant reduction in CR-BSIs.

BACKGROUND: A rapid and sensitive surveillance culture has a pivotal role in infection control of methicillinresistant Staphylococcus aureus (MRSA). This study was aimed to compare the performance of MRSASelect (Bio-Rad, France) to that of mannitol salt agar containing 6 microgram/mL of oxacillin (MSA-OX) for detecting MRSA in surveillance cultures. METHOD: From May to June 2006, 86 nasal swabs and 21 sputum specimens were enrolled. All specimens were inoculated onto MRSASelect and MSA-OX, which were incubated for 2 days and 3 days, respectively, and colonies were read daily by a technologist. Pink colonies on MRSASelect and yellow colonies on MSA-OX were examined with Gram stain, Pastorex(R) Staph-plus (Bio-Rad) and mecA-PCR. After the final reading, both media were re-examined by a superviser. RESULTS: Of the 107 specimens cultured, 32 (29.9%) were positive for MRSA. Of these, 27 were detected by both media, one by MSA-OX only, and 4 by re-examination. The day-1 and day-2 sensitivities/specificities of MRSASelect were 78.1%/97.3% and 84.4%/97.3%, respectively, while those of MSA-OX were 53.1%/100% and 78.1%/92.1%, respectively. With MRSASelect, two more positives were detected at day 2, but their incubation was less than 18 hour at day 1. There were six false positive organisms detected: three Enterobacter spp., one Acinectobacter spp., and two coagulase-negative staphylococci (CNS). But, the two CNS grew on MSA-OX only. CONCLUSION: MRSASelect with 1-day incubation showed a sensitivity equivalent to and a specificity better than MSA-OX with 2-day incubation. MRSASelect should be a useful medium for MRSA surveillance when it is read after an incubation of 18-28 hours with the confirmatory Gram stain of screen-positives.
