    Elderly persons make use of significantly more emergency medical services than do younger adults. The elderly are more prone to medical emergencies such as cardiac arrests, falls or diabetic seizures. Our prototype called portable medical monitoring computer (PMMC) was developed to provide a possible solution to efficient elderly care, especially in such emergency situations. It is an addition to our remotecare system which uses a wireless sensor network (WSN) to monitor the elderly in aged care facilities. PMMC is classified as a touchable medical e-nursing information system to support registered nurses in nursing homes with vital sign parameters and other medical information about residents who are suffering a medical emergency. The `user centred design' application was predicated on the concept of a portable computer with a touch screen, which allows users to access information next to the casualty at the point-of-treatment. The paper reports on the results of usability issues found during testing, specifically with our gesture enabled interface. We suggest improvements to make the interface more intuitive and suitable for humans' interaction. View full abstract»

    This work takes place in the framework of context awareness, with a particular objective to remotely follow up the activities of elderly persons living independently in their own home. Whereas many existing systems for detecting the activity of occupant require large numbers of sensors, invasive vision systems, or extensive installation procedures, we present an approach to extract information from the electrical appliances activities in home. Furthermore, we build a unique indicator which integrates all the activity of the person. Our system was experimented during 6 months within 12 flats occupied by single elderly persons.

    This paper analyzes the economic effect of eHealth system by utilizing the data of ?days spent for treatment?. In the previous paper, we analyzed how and how much eHealth reduces actual medical expenditures by examining Nishi-aizu Town, Fukushima Prefecture, Japan as a case study. In this paper, we compare results of this analysis with those we obtained from the analysis of medical expenditures. eHealth connects senior people at home with medical or health institutions via telecommunications networks, and the town office has been implementing it since 1994 and keeps monthly receipts in the paper form on medical expenditures of approximately 4,000 residents paid by National Health Insurance for five years from 2002 to 2006. The methodology of the analysis is to choose two groups (i) users; and (ii) non-user of eHealth, and compare days spent for treatment. As for the former group, we selected 412 from the list owned by the town office, and as for the latter group, we chose 450 from the list of National Health Insurance. We send questionnaire on their personal characteristics and diseases. We obtained 199 replies from users, while 209 for non-users. Then we examined receipts of these 408 people, and made a database on age, diseases, the first dates of visiting medical institutions for the first time, the number of visiting medical institution, and medical expenditures. Based on this database, we conducted a regression analysis, and obtained the following results: -Result 1: Users of eHealth have smaller days spent for treatment of lifestyle-related illness than those of non-users. -Result 2: Users of longer practicing eHealth have shorter days spent for treatment of lifestyle-related illness than those of non-users. -Result 3: Users of longer practicing eHealth reduce days spent for treatment larger than those who use it shorter years, if they extend usage one more years. -Result 4: eHealth there has more effect to people who have diseases than those who do not. This - paper compares the above results with those we obtained from the analysis of medical expenditures in the previous paper. The analysis and results we obtained provide the rigorous economic foundation of eHealth. View full abstract»

    People with dementia lose their ability to learn, solve problems, and communicate. And they are all around us. To potentially replace some of their diminished memory and problem-solving abilities, erroneous-plan recognition (EPR) aims to detect defects or faults in the execution of correct plans by the dementia patient, and send timely audio and visual prompts to the dementia patient and caregiver in order to correct these faults. The scope of this work is for the patient who lives alone in a smart home. One challenge is that the definition of plan can be very subjective. It is necessary to regard a plan as an activity of daily living (ADL), choose the ADLs to monitor, and deploy available sensors to acquire data. With the sensor data, there can be activity recognition, followed by plan recognition. Another challenge is the highly random and erroneous behaviour of dementia patients. Multiple, sequential, and independent layers of error detection can be arranged in a prioritised manner to detect specific errors first, and provide an error probability if no specific errors are detected. On the whole, most of the EPR results are very good as they are at least 0.9, indicating that the data is linearly separable. The 2-layer EPR system, which uses the blacklist and whitelist as Layer 1 and naive Bayes classifier as layer 2, is significantly more accurate than each individual layer. In fact, 5 out of 6 actors have an accuracy above 0.9. With the encouraging results, there will be more technical and domain challenges which we can address in the near future. View full abstract»

    In this study, we explore whether there is correlation between the personal network and its impact on physical, mental and psychological health of aging population. Previous research on aging and health suggest the importance of individual family network and social network on different aspects of health assessments and outcomes. We examine the impact of family network and social network on physical, mental and psychological health of elderly men and women by using a cross-national sample (N = 4412) from four Eastern Mediterranean countries of Bahrain, Egypt, Jordan, and Tunisia. We analyse the dataset entitled World Health Organisation Collaborative Study on Social and Health Aspects of Aging in Bahrain, Egypt, Jordan, and Tunisia both at a macro and a micro level. Results show that there is a strong impact of family network and social network on individual physical, mental, and psychological health both at a macro and a micro level. View full abstract»

    To respond to the critical needs of the aging society in Taiwan, the relationship between the intelligent environment technology and recreational behavior of the elderly needs to be examined. The purpose of this study is to define the level of demand of the intelligent environment technology on the elderly. To understand the intelligent environment technology, the researchers reviewed literature, conducted interviews, and focus group discussions with the elderly. The study interviewed 430 participants selected from the elderly population in Taipei. One-to-one interviews were conducted by a trained interviewee using a structured questionnaire assessing personal characteristics and weekly leisure-time behavior. The results showed that the safety is the most important and enhancement of convenience is the least important demand for intelligent environment technology. A safe environment is the most demanding issue for the elderly to participate in recreational activities. Based on one-week leisure behavior, the study divided the participants into three groups: home recreational participants (HR), walking distance recreational participants (WDR), and not regular recreational participants (NRR). NRR participants scored significantly higher on the demands compared to other groups. In conclusion, to assist the elderly in recreational participation, intelligent environment technology should focus on the safety issue. Furthermore, intelligent environment technology needs to consider demands of the elderly, especially the NRR group. View full abstract»

    The declining cognitive and motor abilities has become a major problem in the health care of the elderly, often leading to potentially fatal falls. Current rehabilitation strategies to address this issue include routine physiotherapy which is often dull and boring for the patient, leading to poor adherence. In recent years, the use of video games in physical therapy has reportedly had a positive affect on rehabilitation strategies. We propose using a modified version of a music video game, dance dance revolution (DDR), to motivate the elderly and increase adherence to rehabilitation. We also present the design of a mobile monitoring system which allows the health professional to monitor the patient's progress. View full abstract»

    Recent developments have seen increased interest in the effect of end-user attributes on the in-practice effectiveness of systems that detect incapacitating falls and trauma at home. It is hoped that consideration and evaluation of such issues will ultimately result in long-term benefits including earlier crisis detection and response, reduced hospital admissions, and improved quality of life for relatively large groups of people. Key concerns include the needs and capabilities of end-users, the ability to nominate who is to be alerted, security, privacy, interface design and system failures. It is concluded that particularly relevant avenues for further research include end-user characteristics, interface design and peer-to-peer components. View full abstract»

    Many researchers and designers from the private and government sectors have been paying much attention to the issues, policies, challenges and opportunities of bringing healthcare services to patients' homes. Some believe that this would not only ease the workload of the health care practitioners but also reduce the cost of health care treatments. Many topics surround the older adults but few focus on current working adults, who may be the users of the future e-health systems and policies. Compared to older adults, the younger working adults are more tech-savvy and hence more likely to adopt and afford technology-mediated health services. This paper discusses the view points of working adults concerning the adoption of e-health as well as addresses issues concerning innovation and acceptance in their future homes. View full abstract»

    Australia is geographically large and sparsely populated. Thus, its population is subject to inequalities in healthcare based on geographic location. This is particularly true for the management of pregnancies at risk, which require regular monitoring. We discuss a solution in the form of a framework based on inexpensive monitoring devices coupled with a mobile phone and PC systems to enable enhanced monitoring capabilities and remote connectivity. The system has the potential to reduce unnecessary travel for regular checkups. Importantly, this system allows monitoring and diagnosis, as well as support for the mother, to be available remotely at any time allowing problems to be detected earlier so that appropriate intervention can be given if needed.

    Sleep apnea syndrome (SAS), which is associated with symptoms like chronic snoring, sleep apnea, and daytime excessive sleepiness, causes problems in daily lives. It has been pointed out that sleep of those who have apnea attacks is characterized by snoring in many cases, and thus attempts have been made to conduct screening for sleep apnea syndrome by analyzing snoring sounds. However, using snoring sound for screening is not practical at present because enormous effort is required in order to analyze each individual's overnight snoring sound for a clinical application purpose. As just described, screening for sleep apnea syndrome has been regarded as being considerably troublesome. In addition, snoring sound with relatively less noise can be collected in well-equipped environments such as a sleep disorder center, but, collecting snoring sound at home suitable for analysis is likely to be difficult because numerous different kinds of noise sources exist at home. With intent to improve such situations, use of an IC recorder with a bone-conduction microphone and a simple SpO2 monitor was considered and sound processing was used to eliminate noise in this study this time with expectation that such application of those devices will minimize patients' psychological burdens because staying overnight at hospital to undergo an examination in an extensively-equipped room will become unnecessary. As reduction of SpO2 during sleep results in sleep quality deterioration, it was studied if comparison between the SpO2 and pulse data and the snoring sound data, both of which were collected during sleep, could be helpful in order to grasp respiratory status during sleep and evaluate sleep quality, using the main symptom of sleep apnea syndrome, snoring.

    Digital garments or smart clothes with noninvasive smart sensors handling vital signs are expected to be key elements for our health management in the future. A wellness wear system is an integrated system including such smart clothes with sensors acquiring bio-signals, digital yarns transmitting those signals, integrated circuits and microprocessors for digital signal processing, wired and wireless communication, and application software systems providing various medical services based on vital signs acquired. This paper is centered around software aspects for health management in the wellness wear system, introducing a related project launched recently. As a very first and important step for it, we in this paper propose a service framework for software applications as parts of a wellness wear system that provides users with various medical services primarily using vital signs obtained from smart clothes.

    Modern medical practice gives rise to a significant volume of electronic data, and numerous online personal health record (PHR) banking services have emerged to satisfy the growing demand for self-management of this data. These services provide interoperable, centralized repositories that collect this data and make it ubiquitously accessible to patients, providers and referring practitioners by means of a variety of Internet-capable handheld devices. However, these Web-based PHRs currently offer very limited or no support for medical imagery. This is primarily attributed to the security concerns, heterogeneity in the data standards of medical images, and compatibility issues among target platforms. With ever increasing reliance on medical imaging data, the accessibility and interactive visualisation of said data are now becoming a fundamental requirement in PHRs. The aim of our study is to make biomedical image data available for use with handheld devices by means of such web-based PHR, so as to increase patients' access to their image data, and facilitate practitioner collaboration and review, without reducing the mobility that characterises these records. Our proposed system consists of a Web-based interface for the review of nuclear medicine imaging, in particular, dual-modality PET/CT images, on handheld devices, which is embedded within an online PHR, as well as a switchboard dispatch system that allows an archival image server (i.e., hospital information system) to respond securely to interactive visualisation requests made over the Internet. Our support for the complex and large data of dual-modal imaging ensures our work supports the latest in biomedical imaging standards. A key aspect of Internet-based systems is the importance of patient privacy and security issues. Our system uses industry-standard encryption and a remote-service architecture to address the perceived security limitations of PHR systems, and takes advantage of the same Web standards as th- e PHRs themselves to deliver a consistent user experience across all target platforms. Our experimental results suggest that by enabling PHRs to propagate medical image data to Internet capable devices, our system can potentially improve the utility of health record banking.

    In this paper, we propose to provide a better way to monitor one's cardiac health status given today's array of exercise monitors. Built on top of our existing MobiCare technology and using an adaptation of the Fox and Haskell formula for exercise, we have set up an exercise monitor on the mobile phone that will help an individual achieve a certain goal that he or she wants from doing exercise. It could be something simple like better overall cardio fitness or something much more like losing weight. Once the goals and personal information are set for the individual, our exercise monitor program will advise users to achieve the maximal benefits of their exercise without going beyond their own limits. This will be beneficial to people who already have some difficulties to begin their exercise regime. This sports exercise monitor program will help them to gradually increase their duration and adaptation on physical activities and ultimately their general overall fitness. View full abstract»

    This paper provides an overview of the new secure Web interface for the Medical Research Council (MRC) National Survey of Health and Development (NSHD), which is a Web-based data and metadata access system for the longest-running longitudinal study of health in the world. Accessing NSHD metadata and data has often been a challenge for external (non-MRC) users, because the underlying data and metadata formats have changed dramatically in 63 years of operation, and because the processes involved in metadata search and data access were manual and usually required ¿on-site¿ access. The design goals of the SWIFT include maintaining confidentiality and privacy of study members, enabling metadata search access to internal (MRC) and external users, facilitating data downloading and extraction from a range of underlying formats, and implementing procedures to ensure compliance with the governance policies of the MRC and the NSHD's governance panel. This paper details some of the challenges and successes of the MRC pathfinder ¿data access project¿ to enable access using SWIFT while protecting the study members and their data.

    In modern health care, use of Web based EHR (electronic health record) system has increased remarkably because of its world-wide accessibility and the facility of the collaborative work among multiple users. Major drawbacks of such centralized Web based system are link failure and low or no fault tolerance. In an unreliable network, it is very commonplace that service is unavailable due to connection failure. The problem motivates us to devise a decentralized system that would work seamlessly in unreliable Internet infrastructure. In this paper, we have presented such an e-healthcare system (named iMedikD) which supports both local and centralized access where hospitalwise responsibility is delegated among multiple peripheral servers. Therefore, by lowering the dependency over the external links the system is able to keep the peripheral services running uninterrupted. Only in case of remote referral, peripheral servers communicate through external links to Web based servers with a view to minimize bandwidth utilization. View full abstract»

    To perform research and experiment in enhancing the timeliness and efficiency of providing healthcare service in e-Healthcare, a modeling approach is designed and implemented to integrate a parking guidance system (PGS) with an electronic health record (EHR) system. The integrated system provides advanced services for two healthcare groups: 1) patients who need immediate urgent care, and 2) healthcare providers who perform emergency medical services and operations. By entering a zip code of a selected area and patient's basic data, the system would return the three most optimal urgent care providers in the selected area, from which the user of the system can choose and submit essential patient's data to; the system would then return three progressive levels of navigation information: 1) from home to hospital, 2) at hospital's parking facility, and 3) inside hospital; furthermore, the system would reserve a parking space and complete registration prior to the patient's arrival at the hospital's urgent care facility. To provide efficient and convenient e-healthcare services, the integrated system must be available on mobile devices; hence, the server has been implemented as a Web service server, and a mobile Web service client, along with its desktop counterpart, is a part of the integrated system. Lastly, this integrated system addresses various security issues in privacy, integrity and confidentiality of the patient's medical record data. View full abstract»
