치과진료 환경은 병원 미생물에 쉽게 노출되어 종사자의 감염 위험성은 매우 높다. 그중 손은 감염의 중요한 매개가 되므로 손위생은 감염 위험성을 낮추기 위한 가장 중요하고 기본적인 방법이다. 이에 치과진료 과목을 세분화하여 교정치과 진료실의 손위생과 건강신념간의 관련성을 연구하였다. 손위생과 건강신념간의 차이 분석 결과 손 위생 관리 중요도와 손 위생 교육 경험은 유의한 관계를 보였다(p=0.010)(p=0.000). 건강신념에 영향을 미치는 요인 분석 결과 손 위생 관리 중요도(p=0.014), 손 위생 교육 경험(p=0.010)은 유의하게 영향을 미치는 요인이었다. 치과 감염에 대한 관심이 증대되면서 기본적인 방법인 손 씻기의 중요성이 더욱 높아질 것을 예상 할 때 감염관리 교육은 건강신념을 확립하는데 높은 관련성이 있을 것이라 사료된다.

Dental environments are easily exposed to hospital microorganisms, so the risk of infection among workers is very high. Hand washing is one of the most important and basic way to reduce the risk of infection, as hands are an important medium of infection. Therefore, a convergence study was conducted between hand washing and health belief in orthodontic clinic. Analysis of differences between hand washing and health beliefs showed a significant relationship between importance of hand washing and experience in hand washing education (p=0.010) (p=0.000). Analysis of factors affecting health beliefs showed that the importance of hand washing control (p=0.014) and hands washing education experience (p=0.010) were significantly influencing factors. Infections management education is believed to be highly relevant in establishing a health when increasing interest in dental infections is expected to increase the importance of hand washing, a basic method.

Purpose: This study aimed to identify the factors associated with hand washing performance in daily life among paramedic students expected to work in high-risk infectious environments. Unlike previous studies that focused mainly on knowledge or clinical practice contexts, this study examined hand washing behavior in daily life and explored the behavioral and environmental determinants of performance. Methods: This study aimed to identify factors associated with hand washing performance in daily life among paramedic students expected to work in high-risk infectious environments. Unlike previous studies that focused mainly on knowledge or clinical practice contexts, this study examined hand washing behavior in daily life and explored the behavioral and environmental determinants of performance. Results: The mean knowledge score was high (14.30±1.01), whereas performance was relatively lower (48.99±7.11), indicating a gap between knowledge and behavior. No significant correlations were observed between knowledge and performance. Multiple regression analysis showed that not living with parents (β=0.239, p=.003), longer hand washing time (β=0.286, p<.001), and use of air dryers (β =0.203, p=.008) were associated with higher performance, whereas turning off the faucet using bare hands was associated with lower performance (β=−0.153, p=.045). Conclusion: Behavioral and environmental factors influenced hand washing performance more than knowledge alone. This study adds to the existing literature by suggesting that daily life habits, rather than cognitive factors, play a key role in hand washing behavior among paramedic students. These findings highlight the need for practice-based education emphasizing habit formation and repeated training. As the data were collected during the COVID-19 pandemic, interpretation should consider the context of the pandemic.

Purpose: To examine the effects on skin injury, pain, and anxiety when nurses and children simultaneous wash their hands before IV injections. Method: A nonequivalent control group, non-synchronized design study was used with 61 children. For a month and a half, children in the experimental group(30) following hand-washing guidelines, washed their hands with nurses before IV insertion. Anxiety and pain were observed and recorded during IV insertion using the Anxiety Reaction Scale and FACES pain scale. After 48-72 hours on IV therapy with an arm-board, skin condition was checked by a research assistant according to guidelines for assessing skin injury developed by the researcher. t-test, χ²-test, Pearson correlation, and Kendall's tau b were used to analyze data with the SPSS program. Results: Children who washed their hands with the nurse before IV insertion showed less pain (p =.021) and skin injury (p <.001) compared to the control group. Conclusion: This finding suggests that simultaneous hand washing by nurse and child before IV injection has a strong effect on skin injury caused by arm-boards used to maintain IV therapy as well as on pain during IV insertion. This program demonstrates an effective intervention to prevent skin injuries in children on IV therapy.
