Performance Evaluation of an Enhanced Uplink 3.5G System for Mobile Healthcare Applications

The present paper studies the prospective and the performance of a forthcoming high-speed third generation (3.5G) networking technology, called enhanced uplink, for delivering mobile health (m-health) applications. The performance of 3.5G networks is a critical factor for successful development of m-health services perceived by end users. In this paper, we propose a methodology for performance assessment based on the joint uplink transmission of voice, real-time video, biological data (such as electrocardiogram, vital signals, and heart sounds), and healthcare records file transfer. Various scenarios were concerned in terms of real-time, nonreal-time, and emergency applications in random locations, where no other system but 3.5G is available. The accomplishment of quality of service (QoS) was explored through a step-by-step improvement of enhanced uplink system's parameters, attributing the network system for the best performance in the context of the desired m-health services

Group-Slicer: A collaborative extension of 3D-Slicer

AbstractIn this paper, we describe a first step towards a collaborative extension of the well-known 3D-Slicer; this platform is nowadays used as a standalone tool for both surgical planning and medical intervention. We show how this tool can be easily modified to make it collaborative so that it may constitute an integrated environment for expertise exchange as well as a useful tool for academic purposes

Compression of image sequences in interactive medical teleconsultations

Interactive medical teleconsultations are an important tool in the modern medical practice. Their applications include remote diagnostics, conferences, workshops and classes for students. In many cases standard medium or low-end machines are employed and the teleconsultation systems must be able to provide high quality of user experience with very limited resources. Particularly problematic are large datasets, consisting of image sequences, which need to be accessed fluently. The main issue is insufficient internal memory, therefore proper compression methods are crucial. However, a scenario where image sequences are kept in a compressed format in the internal memory and decompressed on-the-fly when displayed, is difficult to implement due to performance issues. In this paper we present methods for both lossy and lossless compression of medical image sequences, which require only compatibility with Pixel Shader 2.0 standard, which is present even on relatively old, low-end devices. Based on the evaluation of quality, size reduction and performance, the methods are proved to be suitable and beneficial for the medical teleconsultation applications

Specialist to non-specialist teleconsultations in chronic respiratory disease management:A systematic review

BACKGROUND: Chronic respiratory diseases (CRD), are common public health problems with high prevalence, disability and mortality rates worldwide. Further uneven distribution of the health workforce is a major barrier to the effective diagnosis and treatment of CRDs. Teleconsultation between a specialist and non-specialist could possibly bridge the gap in access to health care and decrease CRD burden in remote areas. This review investigates the evidence for the effective use of specialist to non-specialist teleconsultation in the management of CRDs in remote areas and identifies instances of good practice and knowledge gaps. METHODS: We searched for articles till November 2020, which focused on specialist to non-specialist teleconsultations for CRD diagnosis or management. Two independent reviewers conducted the title and abstract screening and extracted data from the selected papers and the quality was assessed by Joanna Briggs Institute’s (JBI) tool. A descriptive and narrative approach was used due to the heterogeneous nature of the selected studies. RESULTS: We found 1715, articles that met the initial search criteria, but after excluding duplicates and non-eligible articles, we included 10 research articles of moderate quality. These articles were from nine different studies, all of which, except one, were conducted in high-income countries. The studies reported results in terms of impact on the patients, and the health care providers including primary care physicians (PCP) and specialists. The teleconsulting systems used in all the selected papers primarily used audio modes in addition to other modes like the audio-video medium. The included studies reported primarily non-clinical outcomes including effectiveness, feasibility, acceptability and usability of the teleconsultation systems and only three described the clinical outcomes. The teleconsultation was predominantly conducted in the PCP’s office with the specialist located remotely. CONCLUSIONS: We found relatively few, papers which explored specialist to non-specialist teleconsultation in management of CRDs, and no controlled trials. Two of the included papers described systems, which were used for other diseases in addition to the CRD. The available literature although not generalisable, encourages the use of specialist to non-specialist teleconsultation for diagnosis and management of CRDs

Teleconsultation perspective for cardiovascular patients in Saudi Arabia

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This research of teleconsultation services aims to improve the quality of diagnosis and treatment for rural cardiovascular patients through utilizing distant medical expertise. Equitable access to expert healthcare as well as improved medical management for these patients can assist in modifying cardiovascular disease (CVD) risk and reduce morbidity and mortality in Saudi Arabia. The objectives were to design and develop a new care pathway for cardiovascular disease patients by utilizing teleconsultation technology, investigate factors and issues that might act as barriers to its adoption, and then evaluate the impact of this model on the stakeholders. A small scale pilot project was used to determine the issues of technology, processes and human resources required to deliver an effective service with the context of the research setting. Four primary healthcare centres, two regional hospitals, fifteen patients and sixty other participant stakeholders were included in this study. An approach using (PCP) patient care pathways was used to introduce the teleconsultation technology and integrate it within the healthcare delivery system. Compared to the traditional PCP, the modified PCP utilising teleconsultation technology improved the quality of healthcare through: Improved access to medical care and quality of diagnosis by obtaining the expertise of a distant specialist. More efficient medical evaluation and management. Enhanced role of primary healthcare centres and participating hospitals by providing all levels of health services for patients. Evidence-based referral (reduced waiting time, reduced burden on outpatient clinics). The telconsultation adoption barriers included: Inadequacy of finance Limited infrastructure Legal and regularity difficulties. Organization issues. Literacy on technology. This study recommends the following for telemedicine implementation in the country: Promote perception and readiness for ICT services with the healthcare community. Enhance structural readiness including appropriate infrastructure and adequate funding, human resources and equipment. Proactive policies to encourage growth of the telecommunication sector and to address concerns regarding privacy and security
