Purpose: Exposure to blood and body fluids represents a significant occupational risk for nurses. This study was done to identify the level of knowledge of and compliance with blood-borne pathogen prevention of hospital nurses according to clinical experience, and to identify factors affecting compliance with blood-borne pathogen prevention. Methods: A descriptive correlational study was conducted in which self-reported knowledge of and compliance with blood-borne pathogen prevention was assessed. The relationships between variables were examined. Registered nurses who were employed(n=345) were surveyed. Data were analyzed using, t-test, ANOVA, Pearson correlation, and multiple linear regression. Results: Nurses with more than 5 years experience had greater knowledge of blood-borne pathogen prevention than nurses with less than 5 years experience. However, there was no significant difference in compliance with blood-borne pathogen prevention between the two groups. No significant correlation was found between knowledge and compliance with blood-borne pathogen prevention according to experience standards. In nurses with less than 5 years experience, gender, age, reported exposure to a blood-borne pathogen, and compliance with principles of prevention had a significant impact on compliance with blood-borne pathogen prevention. For nurses with more than 5 years experience, reporting after exposure to blood-borne pathogen was a contributing factor to compliance with blood-borne pathogen prevention. Conclusion: The study results show that to improve the implementation of preventive measures against blood-borne pathogens different strategies are needed, depending on clinical experience of the nurses.

차효성,윤태식,류기정,신일원,최양효,이경용,이재동,류근호,정승현 대한의료정보학회 2015 Healthcare Informatics Research Vol.21 No.2

Objectives: New methods for obtaining appropriate information for users have been attempted with the development of information technology and the Internet. Among such methods, the demand for systems and services that can improve patient satisfaction has increased in hospital care environments. Methods: In this paper, we proposed the Hospital Exam Reservation System (HERS), which uses the data mining method. First, we focused on carrying clinical exam data and finding the optimal schedule for generating rules using the multi-examination pattern-mining algorithm. Then, HERS was applied by a rule master and recommending system with an exam log. Finally, HERS was designed as a user-friendly interface. Results: HERS has been applied at the National Cancer Center in Korea since June 2014. As the number of scheduled exams increased, the time required to schedule more than a single condition decreased (from 398.67% to 168.67% and from 448.49% to 188.49%; p < 0.0001). As the number of tests increased, the difference between HERS and non-HERS increased (from 0.18 days to 0.81 days). Conclusions: It was possible to expand the efficiency of HERS studies using mining technology in not only exam reservations, but also the medical environment. The proposed system based on doctor prescription removes exams that were not executed in order to improve recommendation accuracy. In addition, we expect HERS to become an effective system in various medical environments.

차효성,정승현,류근호,황정희 한국융합보안학회 2014 융합보안 논문지 Vol.14 No.5

국내 대형병원 중심의 통합의료정보시스템은 2000년 초반을 기점으로 부터 처방전달시스템(OCS : Order Communication System)중심에서 전자의무기록(EMR : Electronic Medical Record)시스템을 포함한 시스템으로 확장 발전하고 있다. 하지만, 오늘날의 고도화된 의료정보시스템은 정보 사용자의 요구도가 복잡∙다양해짐에 따라 단위 시 스템으로 개발되어 점차 통합되는 과정에 이르렀고, 이에 따라 대형병원과 같은 복잡한 조직체계에 적합한 의료정보시 스템의 권한관리는 해결되어야 할 큰 문제점이다. 또한 다양한 사용자의 적절한 권한관리의 부재로 인하여 개인정보 및 민감정보 노출의 심각성 또한 대두되었다. 따라서 이 논문에서는 과거 병원정보시스템(HIS: Hospital Information System)의 문제점들을 분석하여 의료정보운영 환경에서의 효율적이고 적합한 권한관리 시스템을 제안한다. 또한 통합 의료정보시스템의 특성에 맞는 적합한 권한 관리를 개발하여 대형병원 EMR 시스템에 적용된 사례를 기술한다. 제안된 시스템은 차세대 EMR을 비롯한 통합의료정보시스템에 맞는 권한관리 솔루션 개발에 기반이 된다. Beginning in 2000, domestic large hospital based integrated health information system has been developed from order communication system to electronic medical record system. However, today's advanced medical information system is integrated with unit of the system because user needs is complex and various. The problem is authority management of health information system in complex systems of large size hospital. It is also a serious problem of private information exposure because of user's authority management defect. In this paper, we analyze the problems of past hospital information system and propose an efficient and appropriate management authority in operating environment. It also introduces the instances applied into a large hospital EMR system, developing proper authority management to match the characteristics of the integrated medical information system. The proposed system is based on solutions of authority management system suitable for integrated health information system, as well as the next generation of EMR.

차효성,양숙자 한국간호과학회 2020 Asian Nursing Research Vol.14 No.5

Purpose: The life satisfaction of Korean adolescents tends to decrease beginning in middle school, and this decrease has a negative effect on life satisfaction in adulthood. Gender and perceptions of parental neglect are important variables influencing the life satisfaction of adolescents in Korea. This study examined the longitudinal mediating effects of perceived parental neglect on the life satisfaction of male and female Korean adolescents to assess changes to the relationships between key variables over time. Methods: The present study analyzed data from 2,215 adolescents from the Korean Children and Youth Panel Survey's fourth-year elementary school panel spanning their first year of middle school (2013) to the first year of high school (2016). A latent growth model was applied to Korean national data. Results: The perceived parental neglect and life satisfaction intercepts differed by gender, and the intercept of perceived parental neglect influenced the life satisfaction intercept. The slope of perceived parental neglect, but not the life satisfaction slope, differed by gender, and the slope of perceived parental neglect influenced the life satisfaction slope. The Sobel method showed that the intercept of perceived parental neglect mediated gender differences in the life satisfaction intercept, and the slope of perceived parental neglect significantly influenced the gender difference in the life satisfaction slope. Conclusion: Efforts to improve adolescent life satisfaction should be differentiated by gender regarding perceptions of parental neglect.

Development and Validation of an Instrument for Measuring Parenting Stress among Clinical Nurses

이경미,차효성 한국간호과학회 2021 Asian Nursing Research Vol.15 No.4

Purpose: Clinical nurses who are mothers of preschool-aged children experience extreme parenting stress linked to their hospital work environment and shift work, differing from that generally experienced by mothers. This study aimed to develop and validate a parenting stress scale that considers the clinical nurses’ form of work and its characteristics. Methods: The scale items were initially derived from in-depth interviews and a literature review and were revised and modified based on the results of content validity testing by experts. The developed instrument was evaluated using data from 157 clinical nurses in South Korea who were mothers of preschool-aged children. Results: In the instrument validation stage, 19 items categorized in four factors (psychological burden, physical and mental fatigue, work shift, and work environment) were derived from construct validity, and the cumulative explanatory power was 56.6%. Furthermore, the convergent and discriminant validity and external construct were confirmed. Cronbach’s a of the final instrument was .86 (range: .81-.86). The validity and reliability of the newly developed parenting stress scale for clinical nurses were established in this study; it uses a 4-point Likert scale. A higher mean score by factor indicates a higher level of parenting stress experienced by clinical nurses. Conclusion: This instrument would be beneficial to measure the level of parenting stress among nurses who work in hospitals and evaluate factors related to their parenting stress to devise effective interventions.

Ensuring the security of medical record is becoming an increasingly important problem as modern technology is integrated into existing medical services. Electronic medical record system is established in independent private network, which provide certifications for medical practice. An outflow of confidential medical information is an invasion of privacy of the person. Advanced medical information system is integrated with unit of the system because user needs is various. It is necessary to control access management of health information system according to user role. In this paper, we propose an efficient and appropriate management authority system and also introduce the instances applied into a large hospital EMR system, developing appropriate access management. to match the characteristics of the integrated medical information system.
