Background: This study aimed to assess the status of infection control during influenza A pandemic (H1N1) 2009. Methods: A questionnaire survey was conducted in November 2009 at the 100 hospitals designated by the Korea Centers for Disease Control and Prevention (KCDC) as influenza A pandemic (H1N1) 2009-treatment institutions. Results: In 32.3% of the hospitals, the ventilation system of the influenza A pandemic (H1N1) 2009 isolation ward was separated from the hospital’s ventilation system. With regard to wearing personal protective equipment while caring for patients with H1N1 infection, during usual patient contact, masks were always worn by all medical staff at all the hospitals; however, medical staff at 38.7% and 51.6% of the hospitals did not wear gloves and gowns, respectively. During aerosol-generating procedures, some medical staff wore surgical masks, whereas medical staff at 10% and 23.3% of the hospitals did not wear gowns and protective goggles, respectively. In all, 64.5% of the hospitals responded that the contents of the guidelines established by the KCDC were insufficient for reference purposes in actual practice. Conclusion: Some of influenza A pandemic (H1N1) 2009-treatment institutions are believed to be inadequate in facilities, infection control during patient treatment, and administrative measures among their efforts to prevent transmission in hospital. In preparation against the outbreak of similar diseases in the future, the government needs to establish guidelines highly applicable by medical staff, to secure exclusive spaces and personnel for treating infectious disease patients, and to develop personal protective gear support and management systems.

Objectives : This study was conducted to evaluate the public's awareness of the importance of hand washing and to compare perceptions on the habit of hand washing with actual hand washing behavior. Methods : Data were collected by observing 2,800 participants washing their hands after using public restrooms in seven cities nationwide and by surveying 1,000 respondents (age > 14 years) through telephone interviews using a structured questionnaire. Results : Although 94% of the survey respondents claimed to mostly or always wash their hands after using public restrooms, only 63.4% of the observed participants did wash their hands after using public restrooms. Significant factors related to increased adherence to hand washing were female gender, approximate ages of 20 to 39 years by their appearance, and the presence of other people from the observation. About 79% of the survey respondents always washed their hands after using bathrooms at home, 73% washed their hands before handling food, and 67% washed their hands upon returning to their home. However, 93.2% and 86.3% of the survey respondents did not wash their hands after coughing or sneezing and after handling money, respectively. Although most of the survey respondents (77.6%) were aware that hand washing is helpful in preventing communicable diseases, 39.6% of the survey respondents did not do so because they were 'not accustomed' to washing their hands and 30.2% thought that washing their hands is 'annoying'. Conclusions : This is the first comprehensive report on hand washing behavior and awareness of the general population in Korea. The result of this study in terms of individual behavior and awareness of hand washing are comparable with similar studies conducted in other countries. However adherence to hand washing is still low and needs to be increased. The results of this study can be used as a baseline in setting up strategies and activities to promote adherence to hand washing.

Background: This study investigated the effectiveness of reinforced contact precautions and active surveillance cultures (ASCs) in reducing the incidence of methicillin-resistant Staphylococcus aureus (MRSA) and other healthcare-associated infections (HAIs). Methods: A before- and after-experimental study was performed at the intensive care unit (ICU) in a university-affiliated hospital. Reinforced contact precautions were applied to all patients, and ASCs for MRSA were performed for newly admitted patients at the time of admission and once a week thereafter. The HAIs were investigated in accordance with the National Nosocomial Infections Surveillance (NNIS) definitions and compared before and after the interventions. The data were analyzed using descriptive statistics. Results: The number of HAIs caused by MRSA decreased from 2.2 to 0.5 per 100 patients discharged (P=0.02) and from 3.6 to 1.0 per 1,000 patient-days (P=0.032). The number of overall HAIs decreased from 7.6 to 4.0 per 100 patients discharged (P=0.011) and from 12.7 to 7.3 per 1,000 patient-days (P=0.034). The invasive device-associated infections caused by MRSA and other pathogens decreased, but the decrease was not statistically significant. Conclusion: Reinforced contact precautions and ASCs were effective in decreasing both MRSA infections and overall HAIs in the ICU. Further, it was assumed that the incidence of device-associated infections would have decreased if the intervention period was extended.

Background: The purpose of this study was to investigate AIDS-specific knowledge, attitudes, and behaviors of auxiliary police on duty in Seoul and to provide basic data for use in AIDS prevention education for auxiliary police. Methods: In November 2008, we questioned 402 auxiliary police in the Mobile Police Force located in Seoul by using a self-administered questionnaire containing 39 items. Results: Of the respondents, 98.5% were unmarried and scored, on average, 2.95±0.98 out of 4 with respect to their knowledge about the transmission routes of HIV infection. Approximately 70.6% of the respondents were sexually active in the past year and 6.3% were diagnosed with or treated for a venereal disease within the past year. Approximately 42.5% of the respondents had sex with someone other than their steady partner and 35.5% of these respondents did not use condom during sexual intercourse. Approximately 77% of the respondents were willing to be anonymously tested for HIV infection that may have been acquired because of unprotected sexual activity during the past year (P=0.018). Conclusion: Providing assertive education, as well as additional support and instructions, is necessary to raise awareness about the prevention of AIDS among auxiliary police.

The effect of hand hygiene was measured by hand culture before and after hand hygiene for 86 nurses, doctors, and nurses aide/housekeepers in Surgical Intensive Care Unit. The subjects were asked to press their dominant hand in hand-shaped Mannitol salt agar immediately after patient contact and then washed their hand by preferred hand hygiene agents [soap and water, waterless alcohol gel, or 4% chlorhexidine gluconate detergent(CHG)], and cultured one hand again. Amount of isolated microorganism was calculated by counting the number of divided areas(1 x 1cm) which is culture positive in hand culture plate. The amount of microorganisms were significantly reduced from 58.1(±38.59) to 27.4(±30.4) cells after hand hygiene. The staff nurse's hand hygiene was more effective compared to medical doctors and nurses aide/housekeepers. Methicillin-resistant Staphylococcus aureus(MRSA) was isolated in 41(47.1%) subjects ; but only removed 100% in 28(32.2%) subjects. When the amount of hand microorganisms was compared by subject's preferred hand hygiene agents, it was decreased in order of 4% CHG, waterless alcohol solution, soap and water, and water. The hand hygiene practice was inadequate to reduce hand microorganisms and significantly different by occupations. Further research and development of hand hygiene improvement program which emphasize the quality of hand hygiene is recommended.

의료종사자의 주사침 손상 사고 후 감염예방처치와 혈액매개바이러스 혈청양성전환

정재심 기초간호학회 2014 Journal of korean biological nursing science Vol.16 No.1

1940년대 이전에 셈멜와이즈와 그의 동료인 콜레차가 비엔나의 의과대학에서 근무 중 주사침 손상을 당하고 연쇄알균 패혈증으로 사망한 사례가 의료종사자가 경피적 사고 후 혈액매개질환에 감염된 사례로 가장 오래된 것이다. 이후 1940년대부터 간염이 의료종사자들에게 문제로 대두되었고, 1984년에 주사침 손상 이후 human immunodeficiency virus (HIV) 감염 사례가 처음으로 보고되었으며, 1987년에 C형 간염이 주사침 손상으로 인하여 전파되었다는 보고가 있었다.

The purpose of this study was to compare the hand disinfection effect of waterless alcohol gel hand washing agent with that of soap and water, 4% chlorhexidine gluconate, and 10% povidone-iodine. Hands of fourty subjects were artificially contaminated with Acinetobacter baumannii 5㎖ and randomly distributed to each hand washing methods. Samples were collected from gloved hand by glove juice sampling procedure. Mean log reduction after hand washing were compared with baseline values. Number of microorganisms were converted to log and tested by ANOVA in SPSSWIN 100. Mean log reduction of soap and water, alcohol gel, 4% chlorhexidine gluconate, 10% povidone-iodine were 2.76±0.62, 2.97±0.56, 4.66±1.70, 4.60±0.91, respectively. The bactericidal effect of alcohol gel was similar to that of soap and water, but the effect was much less than chlorhexidine gluconate and povidone-iodine(p<0.001). In terms of microorganism reduction, the efficacy of waterless alcohol gel was almost the same as soap and water hand washing. Further evaluation of the bactericidal effect of waterless alcohol gel is needed because waterless alcohol gel is simple, convenient, and non-irritating hand washing agent and also very effective in busy hospital environment.
