Purpose: This study was to systematically review the contents and effects of nurse-led transitional care programs for discharged patients from hospital to home. Methods: Randomized controlled trials published between 2005 and 2015 were searched in Pubmed, Embase, Cochrane(Central Register of Controlled Trials) and CINAHL. Data were analyzed using Cochrane Review Manager(Revman) software 5.3. Results: Nine studies were selected and analyzed. Patient assessment, education and discharge planning were included in pre-discharge phase. Referring, communication and care planning were performed by nurses in transition phase. Home and phone visits, monitoring and multidisciplinary advices were included in post-discharge phase. Various outcome measures such as hospital utilization(30 days readmission and emergency department visit), quality of life, and cost were used to identify effectiveness of nurse-led transitional care programs. 30 days readmission(OR=.73, 95% CI 0.54, 0.98; p=.03) and emergency department visit(OR=.67, 95% CI 0.50, 0.88; p=.005) were statistically significant in meta-analysis. However, participant blinding was not done in seven studies which put at the risk of performance bias. Conclusion: The results indicated that nurse-led transitional care program is effective in reducing unnecessary hospital utilization. Nevertheless, small sample size and risk at performance bias are the limitation of this study. Thus, we suggest that well-designed randomized controlled trials need to be conducted.

The purpose of our study is to analyze the determinants of the benefits of the long-term care insurance in Korea using 2008 and 2009 cross-sectional data. Per capita long-term care insurance benefits can be divided into home care services utilization rate, institutional care services utilization rate, per capita home care services benefits, and per capita institutional care services benefits, which are used as the dependent variables in our regression analysis. Admission rate and the ratio of the admitted to the applicant also used as the dependent variables. The results of our analysis show that the explanatory variables such as income level, needs for care, family type, access to the services, and regional characteristics are statistically significant to explain the dependent variables, the long-term care insurance benefits. The higher is the regional income and the more of the female residents, the more are the long-term care insurance benefits. The easier is the access to the services, the more are the insurance benefits. In the rural area, the level of the insurance benefits is relatively high. We propose that copayment rates of the long-term care insurance should be examined and monitoring on the over-use of the services should be done. Also preventive services and care by the family member should be expanded.

Purpose: This study was conducted to examine psychological empowerment and awareness and performance of Healthcare-Associated Infections(HAIs) control among Intensive Care Unit (ICU) nurses. Method: The data for this study were collected using structured questionnaires from 178 nurses working in the ICUs of four hospitals with more than 500 beds. Results: The subjects'psychological empowerment, awareness and performance of HAIs control were mean over. The subjects'psychological empowerment showed statistically significant differences depending on age, marital status, academic background, clinical career, ICU career, and position and experience in infection control among their general characteristics. Awareness of HAIs control showed statistically significant differences depending on age, gender, marital status, clinical career, and ICU career. Performance showed statistically significant differences depending on age, gender, marital status, and, ICU career. Regarding the subjects' performance of HAIs control, there was a statistically significant positive correlation between psychological empowerment and awareness. Conclusion: It was found that it is necessary to strengthen differential customized training according to the subjects'characteristics for effective HAIs control, and to strengthen the nurses'awareness of HAIs control through systematic evaluation, monitoring, and feedback, as well as continuous education and training.

People are willing to spend more for their health. Traditional medical services are hospital-centric and patients obtain their treatments mainly at the clinics or hospitals. As people age, more medical services are needed to exceed the potentials of this hospital-centric service model. In this paper, we present the design and implementation of CardioSentinal, a 24-hour heart care and monitoring system. CardioSentinal is designed for in-home and daily medical services. It mainly focuses on the outpatients and elderly. CardioSentinal is an interdisciplinary system that integrates recent advances in many fields such as bio-sensors, small-range wireless communications, pervasive computing, cellular networks and modern data centers. We conducted numerous clinic trials for CardioSentinal. Experimental results show that the sensitivity and accuracy are quite high. It is not as good as the professional measurements in hospital due to harsh environments but the system provides valuable information for heart diseases with low-cost and extreme convenience. Some early experiences and lessons in the work will also be reported.

Due to the growth of economy and the advancement of IT, the life expectancy has been prolonged and the interests in health have greatly increased. Recently the request for systems that enable measuring the bio-signals of patients in the non medical organizations, such as home, and transmitting them to medical staffs at remote sites for monitoring them. In this paper, we present an agent-based u-health system for patients or suspects with heart diseases. Our system consists of portable devices for measuring bio-signals and agents that perform data collection, data storage, automatic detection of abnormal status in patients, and HL7-based data exchange in a cooperative way. The main features of the system are : the agent-based architecture facilitates the addition of new service modules as well as the modification of existing ones; an intelligent agent is provided which automatically detects situations in which the bio-signals of patients are abnormal; the medical data standard is supported so that the communication with other systems is very easy. To our survey, there have been few previous systems which support all those features in a seamless way.

의학적으로 특별한 주의가 필요한 신생아는 인큐베이터에 들어가게 된다. 인큐베이터는 이러한 유아들을 잘 돌볼 수 있도록 갖춰져 있지만 반드시 병원에 가야하고 너무 많은 비용이 든다. 본 논문은 이러한 인큐베이터의 편의적 그리고 비용적 측면의 문제를 해결할 수 있는 스마트 인큐베이터를 제안한다. 개발된 인큐베이터는 메인 제어 장치로 아두이노 우노를 사용하고 블루투스 통신을 이용하여 근거리 모니터링이 가능하도록 하였다. 인큐베이터 내의 환경은 DHT22 센서를 이용하여 온도와 습도를 측정하고 P5511 소리감지센서를 이용하여 소리를 측정한다. 사용자가 설정한 온도 및 습도 데이터가 기준 값보다 낮거나 높은 경우 컨트롤러를 이용하여 난방 패드를 가동하거나 팬을 돌려 공기 순환이 될 수 있도록 설계하였다. 인큐베이터 내의 측정값은 사용자의 스마트폰 모니터링 화면에 실시간으로 표시되며 앱 인벤터를 이용하여 프로그램하였다. 아기가 우는 경우에는 사용자에게 알람을 제공하여 아기의 상태를 부모가 즉시 알 수 있도록 설계하였다. 개발된 인큐베이터는 가정에서 저렴한 비용으로 유아를 돌보는 데 도움을 줄 수 있다.

Background and Objectives: Self-monitoring of blood pressure (SMBP) is a reliable method used to assess BP accurately. However, patients do not often know how to respond to the measured BP value. We developed a mobile application-based feed-back algorithm (SMBP-App) for tailored recommendations. In this study, we aim to evaluate whether SMBP-App is superior to SMBP alone in terms of BP reduction and drug adherence improvement in patients with hypertension. Methods: Self-Monitoring of blood pressure and Feed-back using APP in Treatment of UnconTrolled Hypertension (SMART-BP) is a prospective, randomized, open-label, multicenter trial to evaluate the efficacy of SMBP-App compared with SMBP alone. Patients with uncomplicated essential hypertension will be randomly assigned to the SMBP-App (90 patients) and SMBP alone (90 patients) groups. In the SMBP group, the patients will perform home BP measurement and receive the standard care, whereas in the SMBP-App group, the patients will receive additional recommendations from the application in response to the obtained BP value. Follow-up visits will be scheduled at 12 and 24 weeks after randomization. The primary endpoint of the study is the mean home systolic BP. The secondary endpoints include the drug adherence, the home diastolic BP, home and office BP. Conclusions: SMART-BP is a prospective, randomized, open-label, multicenter trial to evaluate the efficacy of SMBP-App. If we can confirm its efficacy, SMBP-App may be scaled-up to improve the treatment of hypertension.
