정재심,최정화,이순행,김양수 대한기초간호자연과학회 2003 Journal of korean biological nursing science Vol.5 No.2
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.

정재심,황영희,김용범,류재금,김미경,최소은,박명숙,이향규,이경숙,최스미 기초간호학회 2018 Journal of Korean Biological Nursing Science Vol.20 No.1
Purpose: The purpose of this study was to investigate the extent and the nature of biological nursing science education for clinical nurses in general hospital. Methods: Five advanced general hospitals located in Seoul and Gyeonggi province were conveniently sampled. Contents of education for nurses conducted by the hospital nursing department from January 1 to December 31 of 2015 were collected. Contents of education included biological nursing science and the scope of inclusion and time of assignment were analyzed. Results: A total of 271 cases of nursing education data were collected and 223 cases were analyzed after excluding 48 cases whose contents were not confirmed. Biological nursing science was included in the contents of education for 117 cases (52.5%), but not for 106 cases (47.5%). Regarding the frequency of the biological nursing science education contents, ‘pathophysiology’was the most frequently included (n=286), followed by ‘structure and function of the human body’ (n=191), ‘mechanisms and effects of drugs’ (n=114) and ‘clinical microbiology’ (n=43). Conclusion: Results of this study confirmed that the education for clinical nurses included a lot of biological nursing science related contents. These results can be used as basis for the development of curriculum and training course for nurses.

접촉주의 강화 및 적극적 감시배양 적용에 따른 중환자실에서의 메티실린내성 황색포도알균 감소효과
정재심,최승매,황동희,우준희 대한의료관련감염관리학회 2010 의료관련감염관리 Vol.15 No.2
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.

물 없이 사용하는 알코올 젤의 손소독 효과에 대한 연구
정재심,김덕희,김미나,최명애 대한기초간호자연과학회 2002 Journal of korean biological nursing science Vol.4 No.2
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.
