Improved Hand Hygiene Compliance is Associated with the Change of Perception toward Hand Hygiene among Medical Personnel

이승순,Se Jeong Park,Moon Joo Chung,Ju Hee Lee,Jeong-a Lee,김용균,Hyun Joo Kang 대한감염학회 2014 Infection and Chemotherapy Vol.46 No.3

Background: Hand hygiene compliance has improved significantly through hand hygiene promotion programs that have includedposter campaign, monitoring and performance feedback, and education with special attentions to perceived subjective norms. Weinvestigated factors associated with improved hand hygiene compliance, focusing on whether the improvement of hand hygienecompliance is associated with changed perception toward hand hygiene among medical personnel. Materials and Methods: Hand hygiene compliance and perceptions toward hand hygiene among medical personnel were comparedbetween the second quarter of 2009 (before the start of a hand hygiene promotion program) and the second quarter of 2012. Weassessed adherence to hand hygiene among medical personnel quarterly according to the WHO recommended method for directobservation. Also, we used a modified self-report questionnaire to collect perception data. Results: Hand hygiene compliance among physicians and nurses improved significantly from 19.0% in 2009 to 74.5% in 2012 (P <0001), and from 52.3% to 91.2% (P < 0.001), respectively. These improvements were observed in all professional status or all medicalspecialties that were compared between two periods, regardless of the level of the risk for cross-transmission. Hand hygienecompliance among the medical personnel continued to improve, with a slight decline in 2013. Perceptions toward hand hygieneimproved significantly between 2009 and 2012. Specifically, improvements were evident in intention to adhere to hand hygiene,knowledge about hand hygiene methods, knowledge about hand hygiene indications including care of a dirty and a clean body siteon the same patient, perceived behavioral and subjective norms, positive attitude toward hand hygiene promotion campaign, perceptionof difficulty in adhering to hand hygiene, and motivation to improve adherence to hand hygiene. Conclusions: The examined hand hygiene promotion program resulted in improved hand hygiene compliance and perceptiontoward hand hygiene among medical personnel. The improved perception increased hand hygiene compliance. Especially, theperception of being a role model for other colleagues is very important to improve hand hygiene compliance among clinicians.

The purpose of this research is to study how a collage group art therapy program gives impact on enhancing the disabled college students’ career development capabilities. For this purpose, we had following thesis questions. First, how does a collage group art therapy program give impact on the disabled college students’ career development capabilities? Second, what changes did they experience in their language during the process of having the collage group art therapy? The target group of this study was the handicapped students of A college in Korea. Their career developing competencies were checked through a survey and then eight male and female students who wanted to participate in this program were selected. They joined the group art therapy composed of ten sessions. Each session took ninety minutes and was held once a week. The target group was tested before and after taking the program using SPSS WIN 20.0 Window program. The nonparametric Wilcoxon matched pairs signed-ranks test was adopted to compare and analyze the test results of experimented group’s career development capabilities taken before and after taking the program. Then, the changes of target group’s language usages were checked and recorded to study the changes they experienced for each session. This is how we conclude as a result of conducting the research. First, statistically, the collage g, roup art therapy program brought about significant changes in career development capabilities of the disabled college students. Second, while they took the therapy program, the use of languages related to career development capabilities were more frequently seen as each session develops. The analysis of works they made in each session also revealed that the collage group art therapy was effective in changing the quality of their career developing competencies. Through the group art therapy, the disabled college student who had great difficulties in exploring their career path due to the limited career opportunities and lack of confidence caused by their handicaps could enhance their abilities to explore their future career and understand what to do to plan and prepare for their career.

골육종 환자에서 발생한 Clostridium sordellii 균혈증 1예

문선유,이승순,원지언,김영수,김효정,김한성,강희정,정두련 대한감염학회 2006 Infection and Chemotherapy Vol.38 No.1

Clostridium sordellii is a gram-positive spore forming anaerobic bacillus, rarely encountered in human infection. It produces several exotoxins which contribute to myonecrosis, pulmonary infection, obstetric infection and bacteremia. C. sordellii bacteremia is very rare and has been reported in few patients with malignancy or immunosuppression. To date, there has been no report in Korea. Mortality is high when deep site infection exists regardless of underlying pathology and immune status. In contrast, superficial skin and subcutaneous tissue infection has a favorable prognosis. We present a case of C. sordellii bacteremia in a patient with osteosarcoma. The patient was admitted for the treatment of the infection at the ulcerative osteosarcoma lesions of the leg, and C. sordellii bacteremia was demonstrated. He was successfully treated with intravenous ampicillin/sulbactam for two weeks. Clostridium sordellii는 다른 Clostridium 종에 비하여 인체 감염을 유발하는 경우가 드문데, 균혈증은 세계적으로 몇 개의 증례만이 보고되었으며 국내에선 아직 보고된 바 없다. 악성종양이나 면역 저하 환자에서 주로 발생하는 C. sordellii 균혈증은 특히 심부 감염에 동반된 경우 사망률이 높다. 저자 등은 골육종 환부의 연조직 감염과 관련된 C. sordellii 균혈증 1예를 경험하여 보고하는 바이다.

장간막 림프절염으로 발현된 Kikuchi-Fujimoto병 1예

최원섭,이승순,권진우,이영석,김선영,전선영,김민정,정두련 대한감염학회 2006 Infection and Chemotherapy Vol.38 No.5

Kikuchi-Fujimoto disease or histiocytic necrotizing lymphadenitis is a benign, rare, self limitimg disease presenting with mainly cervical lymphadenopathy and fever unresponsive to antibiotics or medical treatment. A 28-year old man presented with fever and right lower quadrant abdominal pain. Physical examination showed abdominal tenderness and rebound tenderness mimicking acute appendicitis. Imaging studies showed normal appendix and other abdominal organs except enlarged multiple mesenteric lymph nodes. Symptoms persisted despite antimicrobial therapy. Multiple tender lymph nodes were palpable on bilateral cervical area at the 7th hospital day. The biopsy of the neck node showed large areas of patchy, irregular necrosis with prominent nuclear debris surrounded by T lymphocytes, histiocytes without neutrophils and granuloma, so he was diagnosed as Kikuchi- Fujimoto disease. With conservative management, clinical improvement was observed. We suggest that Kikuchi-Fujimoto disease with mesenteric lymphadenitis should be added to the differential diagnosis of acute abdomen mimicking acute appendicitis in young adults. Kikuchi-Fujimoto 병은 주로 경부 림프절을 침범하는 질환이지만, 드물게 회맹부 장간막 림프절을 침범하여, 발열을 동반한 우하복부 통증과 반발압통을 나타내는 장간막 림프절염을 일으킬 수 있다. 급성 충수돌기염과 유사한 양상의 급성 복증을 호소하는 젊은 성인의 경우, 장간막 림프절염 여부를 확인하여야하며, 그럴 경우 Kikuchi- Fujimoto 병을 감별 진단에 포함시켜야 한다. 저자 등이 경험한 장간막 림프절염으로 발현된 성인의 Kikuchi- Fujimoto 병 1예는 국내에서는 최초로 발견된 것이기에 문헌 고찰과 함께 보고하는 바이다.

전기범,이승순,김현수,김재석,이영경,송원근,김한성 대한임상미생물학회 2020 Annals of clinical microbiology Vol.23 No.2

Background: Carbapenem-resistant Acinetobacter baumannii (CRAB) has emerged as an important nosocomial pathogen.The purpose of this study was to determine the effective methods for performing surveillance cultures of CRAB. Methods: Nasal and rectal swabs were obtained concurrently from hospitalized intensive care unit patients colonized with CRAB. All the samples were inoculated in CHROMagar Acinetobacter medium with CR102 (CHROMagar), MacConkey agar medium supplemented with 5 μg/mL imipenem (MCA-IPM), and triptic soy broth medium supplemented with 5 μg/ mL imipenem (TSB-IPM). CRAB detection rates for each sample were compared. Results: The CRAB detection rate in either one of the nasal or rectal swabs from the 37 patients tested were 89.2% (33/37) with the use of CHROMagar, 78.4% (29/37) with the use of MCA-IMP, and 86.5% (32/37) with the use of TSB-IMP. Conclusion: We determined that concurrent use of both nasal and rectal swabs and CHROMagar could be an effective method for CRAB surveillance cultures.
