Patient empowerment is a necessary pre-requisite of effective disease self-management. Self-management can help people with chronic diseases to remain in the workforce and active members of their community. Programs on chronic disease self-management teach and support patients to identify warning symptoms, measure and evaluate vital signs, decide the most suitable treatment for them, and take medications. In the context of the REACTION project, a diabetes management platform for patients in rural areas was designed and developed. In this paper we present the patient portal, the methodology adopted for the technology evaluation and our preliminary results after an extensive field test on citizens with diabetes.

We exploit the interoperability and wide range of specializations to implement four physiological devices and three environmental sensors. Within our projects, we have demonstrated the versatility of the Continua architecture by implementing the AHD within a smart meter, a wall socket plugin gateway and PC based application. We are evaluating clinical impact of the integrated sensor platform to manage frail elderly and diabetes patients. Experience shows that the standards provide the advantage of a rapid development environment, and will offer an increasingly wide range of commercial devices as they are adopted.

We have used a Neural Network (NN) on data from a self-applied questionnaire to implement a decision system designed to seek out high risk individuals in a large population. A Multi-Layered Perceptron (MLP) was trained with risk factors to distinguish CHD. We also describe a modification to the architecture of the neural network in which an extra layer of neurons is added at the input. We present possible interpretations of the weights of these neurons, and show how they can be used as a selection criteria for which questions to use as inputs. The technique is compared against other statistical methods. We go on to demonstrate the system's capability for detecting both the symptomatic and asymptomatic patient.

If there is uncertainty, the lowest-risk strategy is often to transfer the patient. Video consultation allowing the specialist team to see and talk to the patient and local clinician while still in the emergency department could improve decision-making for patient transfer. Objective The aim of this study is to assess the potential benefit of real-time video consultation between remote specialists and emergency department patients and clinicians across all specialties. Methods Detailed patient data were collected prospectively for 6 months (between January 16, 2012, and July 15, 2012) on all patients presenting to a district general hospital emergency department who required input from a specialist team at the nearest tertiary care center. These patients were discussed retrospectively...

It is essential to gain an understanding of the factors that influence acceptance of technologies when they are introduced as part of the monitoring and management of clinical conditions. This study undertakes semi-structured interviews of elderly patients being monitored for Chronic Obstructive Pulmonary Disease (COPD), Congestive Heart Failure (CHF) or diabetes to determine the factors they deemed most important for acceptance of the technology. 18 women and 12 men with age range 65–90 and mean 77 years were interviewed. Nine main themes emerged; attitude to aging and illness, coping strategy, relationship and support, patient-doctor interaction, incorporating patients, self-efficacy, personality, personal meaning, and knowledge. The themes were grouped to three constructs; age/illness, patient, and healthcare practitioner, that were considered as the basis of a ...

It describes the findings from preliminary phase of otherwise a larger longitudinal study. Using Giddens's concepts from structuration theory and consequence of modernity, we were able to acknowledge trust and sense of security as two very salient aspects that govern adoption of new technological innovation. Unattended, these aspects contribute to arousal of conflict and contradiction within a system. In order for successful telehealth implementations in health care setting, providers of the service, need to focus on ways in which clinical users' trust can be gained and sense of security can be promoted while using the telehealth service and technology.

Therefore, the perceptions of the health care professionals regarding security are of interest, as the patients trust them to make informed decisions on issues concerning their privacy, data, and health. Eight health care professionals were interviewed to determine their perceptions and knowledge of security in health care. The research further examines one specific aspect of security which is considered of significant concern: the authenticity of a device being from the actual manufacturer and not a counterfeit. This research proposes device registration together with digital signatures and one-time passwords to address the issue of counterfeit remote patient-monitoring devices and identify and authenticate the user of the device.

The aim of the UK pilot located in Chorleywood, West Hertfordshire has been to bring together primary and social care in order to improve referral, sharing of information and identification of those patients in need. Similarly, the main objective of the Konstantopouleio General Hospital of Nea Ionia Greek pilot in the inCASA project is to develop an integrated healthcare service for patients suffering from Heart Failure.

For the UK pilot, services to monitor the vital signs of patients in residential care homes by remote health care workers have been established. In particular, the aim was to allow the resident's own GP to observe the ECG, blood pressure, SpO2, temperature and respiration whilst still in the health centre and be able to advise on the most appropriate action should a crisis occur. As outcomes, this pilot project was designed to determine feasibility, channels of communication between key players and assess the technology. Trials have been under way for four months and preliminary results are promising. Residential home staff have commented on the extra level security they feel in being able to "summon" medical support for residents for whom they may have concern. Patient's relatives have also commented on the reassurance they experience from knowing that the resident is being monitored.

However, despite its clearly demonstrated potential, RPM has not become an integrated part of patient care so far. In this paper, we undertake an extensive systematic literature review to identify the typical setup of RPM projects and services in the UK. We then propose a solution for a clinically and organizationally more integrated service, which is based in primary care. Key to the design is the involvement of other healthcare services such as social care, the emergency department of a hospital, and out-of-hours General Practitioner services, and also the involvement of the patient and their carer/s. This allows a team-based approach with information-sharing across different healthcare sectors, and offers maximum continuity of care for the patient.

Twenty-two sequential patients referred by a single general practice to a vascular centre were offered a telemedicine clinic appointment as an alternative to a conventional hospital outpatient appointment. A referral pro forma and digital photograph (where appropriate) were transmitted in advance of the videoconference. The videoconference involved patient, practice nurse and vascular consultant. All patients opted for the teleconsultation. The majority had leg ulceration or leg pain. Six patients required only the initial teleconsultation and were managed thereafter in the community. Thirteen were referred to the vascular laboratory for investigation. Three proceeded to angioplasty and four to surgery. Two patients had a conventional outpatient appointment for follow-up but a...

The system allows vital signs to be transmitted to a central server. The medical professional may then observe the data and provide advice to the staff on optimum management. Our system has been evaluated for 18 months and largely provided routine measurements. R Re es su ul lt ts s: : During this period, three residents presented with non specific symptoms that were investigated using the RPM system. One patient had symptoms over a weekend, and the problem remained unresolved on Monday. The resident continued to only complain of feeling unwell, but reported no specific symptoms. Vital signs data were then sent and the doctor consulted. The electrocardiogram (ECG) showed significant ST segment changes. Repetitive measurements of the ECG, heart rate, and oxygen saturation of the blood (SpO2) were made every 5 minutes. The resident had a history angina and CHF. The staff were asked to give the patient aspirin and anti-angina drug. The ECG was seen to resolve after 40 minutes, but the SpO2 was falling. The decision to send to hospital was taken at this point. Two further patients with significant ECG changes were observed during the period of the project, and again both were asymptomatic, but in these cases the condition resolved and hospital admission was avoided. Feedback from users has been very positive. Staff found that the system gave them support to make better informed decisions on patient management, especially when determining whether to admit the person to hospital when reaching end of life. Further comments were that the system also proved useful to reassure relatives during these final stages. C Co on nc cl lu us si io on n: : Our project demonstrated that significant cardiac events occur in the elderly population of residential homes without symptoms; and that RPM can be used by non medical staff to manage asymptomatic patients in the community.

Healthcare professionals, including consultants, doctors and nurses, are engaged in what is seen as a radical action plan for improving the National Health Service (NHS) in the UK. A major focus of this plan is the greater empowerment of the patient, and providing them with more information about their health needs and care. Information and communication technology has the potential to effectively support the complexities involved in the communication that takes place both amongst healthcare workers themselves and between healthcare workers and their patients in both primary and secondary care both in the UK and elsewhere. This paper explores the challenges involved in human interaction and describes how AIDMAN, a clinical information system, allows for richer communication between the patient and those involved in their health.

Two people reviewed 125 articles independently and selected 13 articles for final review. These studies concerned 3480 patients. The follow-up period of the studies was 3-15 months. Pooled estimate results showed that there was an overall reduction in all-cause mortality (P = 0.02). There was no overall reduction in all-cause hospital admission (P = 0.84), although there was a reduction in CHF hospital admission (P = 0.0004). There was no reduction in all-cause emergency admission (P = 0.67). There was no significant difference in length of stay in hospital, medication adherence or cost. Telemonitoring in conjunction with nurse home visiting and specialist unit support can be effective in the clinical management of patients with CHF and help to improve their quality of life.

Conventional approaches based on a fixed threshold applied to a single SpO2 reading to detect deterioration in patient condition are known to have poor accuracy and result in high false alarm rates. This study develops and evaluates use of a dynamic threshold algorithm to reduce false alarm rates. Daily data from four COPD patients with a record of clinical interventions during the period were selected for analysis. We model the SpO2 time series data as a combination of a trend and a stochastic component (residual). We estimate the long-term trend using a locally weighed least squares (low-pass) filter over a long-term processing window. Results show that the time evolution of the long-term trend indicated exacerbation with improved accuracy compared to a fixed threshold...
