The purpose of the study is to examine healthcare workers’ hand hygiene perception, knowledge, and self-reported compliance in accreditated long-term care hospitals in Korea. Perceptions on hand hygiene before and after the national accreditation are compared. We further investigated factors associated with perception, knowledge, and compliance. The introduction of national mandatory accreditation on long-term care hospitals since 2013 resulted in improved hand hygiene compliance and perception among hospital workers. Self-reported hand hygiene compliance rate was 89.7%. Perception is strongly in favor of hand hygiene compliance. Additionally, education level, profession department, and hand hygiene education exposure increased the likelihood of self-reported hand hygiene compliance. Results have implications for efforts to increase hand hygiene compliance rate and improve patient safety culture in long-term care hospitals.

In response to the Health Insurance Portability and Accountability Act of 1996, the U.S. Department of Health and Human Services issued the Privacy Rule in 2003. Since the Privacy Rule allows for the use and disclose of ‘protected health information (PHI)’ under certain circumstances, we reviewed when and how PHI could be disclosed and, to that end, how the individual right is protected under the Privacy Rule. The Privacy Rule permits the use and disclose of PHI with individual’s authorization. However, health services research which usually deal with population-level data would be impracticable if millions of individual authorizations are required. Thus, in addition to the individual’s authorization, the Privacy Rule further allows for the following ways to use and disclose PHI for research purposes: 1) obtain waiver or alteration of the authorization requirement by and IRB or Privacy Board, 2) use de-identified data set, and 3) use limited data set under data use agreement. The Privacy Rule also grants individuals rights, including access to their protected health information, the right to amend, and the right to an accounting of the disclosures of their information. To this end, the Privacy Rule protects the privacy of individual health information, while at the same time allows researchers to have access to the individual health information necessary to conduct the research. The review of federal individual information protections in the U.S. provides insights on establishing appropriate laws and regulations in Korea on individual privacy protection and the use and disclose of personal information for public interest.

신경망과 의사결정 나무를 이용한 충수돌기염 환자의 재원일수 예측모형 개발

충수돌기염 환자의 LoS(Length of Stay)를 예측하는 것은 병상의 운영에 적지 않은 영향을 준다. 본 논문에서는 Neural Networks와 Decision Tree를 이용하여 LoS와 연관이 높은 입력변수들을 찾아 그 의미를 분석하며, 찾아낸 입력변수들을 이용하여 다양한 LoS 예측 모형을 개발하고 그 성능을 비교하였다. 모형의 예측 정확성을 높이기 위하여 Bagging과 Boosting 등의 Ensemble 기법도 적용하였다. 실험 결과, Decision Tree 모형이 Neural Networks 모형보다 좀 더 적은 수의 속성을 가지고도 거의 통일한 예측력을 보였으며, Ensemble 기법 중에서는 Bagging 기법이 Boosting 기법보다 좋은 결과를 보여주었다. 의사결정나무 기법은 Neural Networks 기법에 비해 설명력이 있으며, 충수돌기염의 LoS 예측에 매우 효과적이었고, 중요 입력 변수의 선정에도 좋은 결과를 보여줌에 따라 향후 적극적인 기법의 도입이 필요하다고 할 수 있다. For the efficient management of hospital sickbeds, it is important to predict the length of stay (LoS) of appendicitis patients. This study analyzed the patient data to find factors that show high positive correlation with LoS, build LoS prediction models using neural network and decision tree models, and compare their performance. In order to increase the prediction accuracy, we applied the ensemble techniques such as bagging and boosting. Experimental results show that decision tree model which was built with less number of variables shows prediction accuracy almost equal to that of neural network model, and that bagging is better than boosting. In conclusion, since the decision tree model which provides better explanation than neural network model can well predict the LoS of appendicitis patients and can also be used to select the input variables, it is recommended that hospitals make use of the decision tree techniques more actively.

The study aims to describe the temporal trends in the use of hospitals according to the colorectal cancer treatment types in Korea and to examine the access to care within patients’ residential areas. We used The Korean National Hospital Discharge in-depth Injury Survey. The total of 953,709 colorectal cancer patients is identified during the study period. The four cancer treatment types are used for the analysis: surgical operation, non-surgical treatment, both surgical and non-surgical treatment, and none of any treatment type. Different types of cancer treatment were associated with the size and location of hospitals. While patients under surgical operations tend to use hospitals with more than 500 beds in metropolitan cities, overall use of hospitals in metropolitan cities and/or with more than 500 beds is decreasing. The study results suggest that small-to-medium sized hospitals need to specialize in cancer treatment types such as radiation therapy, pain therapy, and hospice. Regional cancer centers with cancer type specialty would be another alternative to improve access to care among patients in small-to-medium-sized cities.

요양병원평가가 요양병원 종사자의 근무환경, 직무만족과 서비스 질에 미치는 영향

Purpose: The purpose of this study is to evaluate the work environment and job satisfaction of hospital workers and to assess their effects on quality of services under the national long-term care hospital evaluation (hereafter, national evaluation), which has implemented since 2008. Methods: A self-administered survey was conducted on 178 hospital workers" at 18 hospitals in Chungcheong province, Korea. Survey questionnaires include questions about respondent" awareness of the national evaluation and any change in work environment and job satisfaction under the national evaluation. We used a path analysis to assess the effects of work environment and job satisfaction on quality of services. Results: Results showed that the effects of the national evaluation on work environment and job satisfaction were positive, which, in turn, leads to better quality of services. Improvements in the work environment under the national evaluation have resulted in increased job satisfaction. High scores for job satisfaction showed a significant association with the quality of services provided in long-term care hospitals. In addition, the national evaluation itself had a positive effect on improving quality of services. Conclusions: In order to facilitate quality improvement activities under the national evaluation, it is suggested that workers be provided with education and training. Continuous efforts to improve work environment and to enhance job satisfaction would lead to provision of better quality of services in long-term care hospitals.
