Video calls for dispatcher-assisted cardiopulmonary resuscitation can improve the confidence of lay rescuers–surveys after simulated cardiac arrest

Bolle SR et al, Journal of Telemedicine and Telecare, 17(2)

Many mobile phones allow two-way video communication, which permits callers to hear and see each other. If used during medical emergencies, bystanders can receive supervision and guidance from medical staff based on visual information. We investigated whether video calls from mobile phones could improve the confidence of lay rescuers. High school students (n = 180) were randomly assigned in groups of three to communicate via video calls or via ordinary mobile phone calls. They received realtime guidance from experienced nurse dispatchers at an emergency medical dispatch centre during 10-min scenarios of simulated cardiac arrest. Each student answered a questionnaire to assess understanding, confidence and usefulness of the technology. The mean age was 17.3 years in the video group and 17.9 years in the audio group.

Can information technology improve the performance of remote monitoring systems?

Bas M et al, Telemedicine and e-Health, 16(9)

Despite some clinical, economic, and other qualitative advantages associated with remote cardiac device monitoring systems, one of the main challenges concerns the management of the out-of-hospital data. Manual updating of hospital databases with the data stored in the manufacturers’ servers increases time requirements and may introduce mistakes in the entries. The use of communication standards such as Health Level 7 for data interchange could provide a safe and easy way to access patient and device information. The present study of 38 patients was carried out with the Carelink┬« remote monitoring technology. A formal process for remote cardiac device monitoring was established, including some features in the Arrhythmias Information System: mobile phone and e-mail were included for communication between patients and hospital, with a new gateway for automatic message sending.

Non-contact, automated cardiac pulse measurements using video imaging and blind source separation

Poh M et al, Optics Express, 18(10)

Remote measurements of the cardiac pulse can provide comfortable physiological assessment without electrodes. However, attempts so far are non-automated, susceptible to motion artifacts and typically expensive. In this paper, we introduce a new methodology that overcomes these problems. This novel approach can be applied to color video recordings of the human face and is based on automatic face tracking along with blind source separation of the color channels into independent components.

Effects of internet-based tailored advice on the use of cholesterol-lowering interventions: a randomized controlled trial

Webster R et al, J Med Internet Res, 12(3)

Background:
Elevated low-density lipoprotein (LDL) cholesterol is a leading risk factor for cardiovascular disease. Despite the availability of proven interventions to lower LDL cholesterol, their use remains subobtimal. Many websites provide interactive, tailored advice on cardiovascular risk in an attempt to help bridge this evidence-practice gap, yet there is little evidence that provision of such a tool is effective in changing practice.

Assessment of a telemedicine innovation in cardiology

Masella, Cristina, and Paolo Zanaboni, International Journal of Healthcare Technology and Management, 10(4/5)

Recently, in all of the national health systems, the need to keep health costs under control and to assure high-quality standards shifted the attention from hospitals to primary cares, territorial structures and patient homes. In this context, telemedicine represents a strong feature to satisfy the need for new clinical management approaches allowing patients with chronic diseases to effectively receive care in a home setting.

Effects of cardiac rehabilitation referral strategies on referral and enrollment rates

Gravely-Witte, Shannon et al, Nature Reviews. Cardiology, 2009

Despite recommendations in clinical practice guidelines, evidence suggests that utilization of cardiac rehabilitation (CR) following indicated cardiac events is low. Referral strategies, such as automatic referral, have been advocated to improve CR utilization. In this Review, we evaluate the effects of referral strategies on rates of CR referral and enrollment. Referral strategies are categorized as ‘automatic’ (the use of electronic health records or systematic discharge order sets), as ‘liaison’ (discussions with allied health-care providers), or as ‘other’ (for example, the use of motivational letter to patients).

Development of a Portable Linux-Based ECG Measurement and Monitoring System

Tan, Tan-Hsu et al, Journal of Medical Systems, 2009

This work presents a portable Linux-based electrocardiogram (ECG) signals measurement and monitoring system. The proposed system consists of an ECG front end and an embedded Linux platform (ELP). The ECG front end digitizes 12-lead ECG signals acquired from electrodes and then delivers them to the ELP via a universal serial bus (USB) interface for storage, signal processing, and graphic display. The proposed system can be installed anywhere (e.g., offices, homes, healthcare centers and ambulances) to allow people to self-monitor their health conditions at any time. The proposed system also enables remote diagnosis via Internet.

Implications of the Turing completeness of reaction-diffusion models, informed by GPGPU simulations on an XBox 360: cardiac arrhythmias, re-entry and the Halting problem

Scarle, Simon, Computational Biology and Chemistry, 33(4)

In the arsenal of tools that a computational modeller can bring to bare on the study of cardiac arrhythmias, the most widely used and arguably the most successful is that of an excitable medium, a special case of a reaction-diffusion model. These are used to simulate the internal chemical reactions of a cardiac cell and the diffusion of their membrane voltages. Via a number of different methodologies it has previously been shown that reaction-diffusion systems are at multiple levels Turing complete. That is, they are capable of computation in the same manner as a universal Turing machine. However, all such computational systems are subject to a limitation known as the Halting problem. By constructing a universal logic gate using a cardiac cell model, we highlight how the Halting problem therefore could limit what it is possible to predict about cardiac tissue, arrhythmias and re-entry.

Adherence among telemonitored patients with heart failure to pharmacological and nonpharmacological recommendations

Ramaekers, Bram L.T. et al, Telemedicine Journal and E-Health, 15(6)

In many healthcare systems, the outcomes of care for patients with heart failure (HF) are in need of improvement. By applying telemonitoring, this study aimed to assess its short-term impact on patients’ disease-specific knowledge, adherence, and depression. As part of a larger trial (N = 1,023, 17 centers), this study reports preliminary findings among 101 patients from three Dutch hospitals. Patients were randomized to receive care using telemonitoring or standard care. Data concerning patients’ disease-specific knowledge, adherence to pharmacological and nonpharmacological recommendations, and depression were collected by postal questionnaires. In this study, data collected before randomization and 3 months afterwards were analyzed.

Predicting need for intervention in individuals with congestive heart failure using a home-based telecare system

Biddiss, Elaine et al, J Telemed Telecare, 15(5)

We have studied how well the need for a medical intervention can be predicted by a telecare monitoring system. During a study period of about 18 months, 45 elderly individuals with congestive heart failure used a home health monitor to enter daily information pertaining to their symptoms and health status. A total of 8576 alerts were generated by the monitoring system, although in most cases, patient and service provider interaction was not required. When system alerts were considered to be serious, or if symptoms persisted, the patient was contacted.

Application of Neuro-Fuzzy Technology in Medical Diagnosis: Case Study of Heart Failure

Akinyokun, Charles O. et al, IFMBE Proceedings 2009, 25/12

A neuro-fuzzy expert system is proposed for the diagnosis of heart failure. The system comprises; knowledge base (database, neural networks and fuzzy logic) of both the quantitative and qualitative knowledge of the diagnosis of heart failure, neuro-fuzzy inference engine and decision support engine. The decision support engine carries out the cognitive and emotional filtering of the objective and subjective feelings of the medical practitioner. An experimental study of the decision support system was carried out using cases of some from three hospitals in Nigeria with the assistance of their medical personnel who collected patients’ data over a period of six months. The results of the study show that the neuro-fuzzy system provides a highly reliable diagnosis, while the emotional and cognitive filters further refine the diagnosis results by taking care of the contextual elements of medical diagnosis.
