Academic literature on the topic 'Wireless communication systems in medical care – Uganda – Evaluation'

Connected health is the convergence of medical devices, security devices, and communication technologies. It enables patients to be monitored and treated remotely from their home or primary care facility rather than attend outpatient clinics or be admitted to hospital. Patients’ data and medical records within a connected health system should be securely transmitted and saved for further analysis and diagnosis. This paper presents a reconfigurable wireless system for electrocardiogram (ECG) monitoring which can be deployed in a connected health environment. Efficient field programmable gate array (FPGA) implementation for the ECG encryption block has been carried out on the RC10 prototyping board using the advanced encryption standard (AES) algorithm. Results presented have shown that the proposed AES implementation outperforms the existing FPGA-based systems in different key performance metrics and that ECG signals acquired using the VitalSens device can be encrypted/decrypted in real-time. A software based evaluation approach has been also performed to validate the proposed hardware implementation. The proposed solution can be deployed for electronic archiving of health records information systems and health monitoring technologies in personalized medicine.

Novel circular polarized sensors and antennas for biomedical systems, energy harvesting, Internet of Things (IoT), and 5G devices are presented in this article. The major challenge in development of healthcare, IoT, 5G and communication systems is the evaluation of circular polarized active and passive wearable antennas. Moreover, a low-cost wearable sensor may be evaluated by printing the microstrip antenna with the sensor feed network and the active devices on the same substrate. Design considerations, comparison between simulation and measured results of compact circular polarized efficient sensors for wireless, 5G, energy harvesting, IoT, and medical systems are highlighted in this article. The electrical performance of the novel sensors and antennas on and near the user body were evaluated by employing electromagnetic software. Efficient passive and active metamaterial circular polarized antennas and sensors were developed to improve the system electrical performance. The wearable compact circular polarized passive and active sensors are efficient, flexible, and low-cost. The frequency range of the resonators, without Circular Split-Ring Resonators CSRRs, is higher by 4% to 10% than the resonators with CSRRs. The gain of the circular polarized antennas without CSRRs is lower by 2 dB to 3 dB than the resonators with CSRRs. The gain of the new passive antennas with CSRRs is around 7 dBi to 8.4 dBi. The bandwidth of the new circular polarized antennas with CSRRs is around 10% to 20%. The sensors VSWR is better than 3:1. The passive and active efficient metamaterials antennas improve the system performance.

Purpose – The purpose of this paper is to report on use of the IEC80001 standard, Application of Risk Management for Information Technolody (IT) Networks Incorporating Medical Devices, to deploy a wireless alarm management solution in a long-term care home facility. Design/methodology/approach – The standard suggests the use of a unique responsibility matrix and a continuous quality improvement approach for analysis, evaluation and control of risks. A unique leadership committee and workgroup were formed to develop processes and procedures for integrating medical devices with IT systems; as well as execution of the project itself. The leadership committee oversaw the phased approach of assessing the technology, the clinical environment, proponent technology-based solutions and a specified risk management file. The project expanded its scope beyond the standard to include a risk focussed analysis of clinical workflow to evaluate the usability of the solution. Findings – The standard focussed approach identified numerous risks associated with the technical and network solution and the future state workflow. Medical devices proved to be the most limiting technology needing to be incorporated into the solution. Although faced with a daunting list of network related risks, it was concluded that all residual risks would have been acceptable. The analysis of the future state workflow identified various risks related to usability (human factors), battery management and the absence of additional operating dollars for supplementary staffing duties and new operational expenses. Originality/value – To the best of the authors knowledge, this paper is the first one to detail the process of following the IEC80001 standard in Canada. It offers insight into building an organizational framework around the standard and identifies gaps that should be considered by executive and project sponsors before proceeding with a project.

Introduction: The future of healthcare systems relies on faster communication between sensors and smart devices, which can assist in taking decisions for betterment of patients. The responsiveness of wireless health care system in case of medical urgencies is crucial factor for survival of patient’s life. The routing protocol of infrastructure less based are playing key role in sending the information in such medical related emergencies. Therefore, it is important to study and identify the best routing protocol in wireless healthcare based system using Mobile Ad-hoc networks (MANETS). Methods: MANET routing protocols such as Ad-hoc On Demand Vector (AODV), Secure AODV (SAODV) and Hybrid Wireless Mesh Protocol (HWMP) through their routing environment are simulated through this research study. It is essential to highlight the effect of various attacks affecting the routing methodology of these protocols. Since Distributed Denial of Service (DDoS) attack is popularly talked about and is most vulnerable attack present in MANET environment, so this research study analyses AODV, SAODV and HWMP under DDoS attacks through various simulation parameters. Results: In this research study, most suitable routing protocols to handle DDoS attacks are simulated and estimated in terms of delay and packet delivery ratio in the scenario of changing nodes. This aids in providing implications to enhance existing protocols and alleviate the consequences of DDoS investigation by such attacks. Discussion: For ensuring the optimized routing, privacy and security of patient’s data during transmission in healthcare sector, MANET could be used as one of the important technology combined with IoT. For dealing with end to end data transmission of patient's sensitive data, MANET protocol plays a vital role in sending the information securely. Conclusion: The performance of AODV, SAODV and HWMP (Hybrid Wireless Mesh Protocol) are compared and tabularized which are the most popularly utilized protocols in healthcare environment. The simulation results shows that the HWMP out performed than AODV and SAODV routing protocol, in terms of evaluation metrics namely end-to-end delay and Packet Delivery Ratio (PDR) and could be considered as much less vulnerable against DDoS attacks prevailing in wireless healthcare sector using MANET.

The healthcare and the management of quality is very essential part to the recent period of medical environment. To enhance these, to make sufferer easy with timely and best remedial care.EEG systems are closely relevant on the performance using wireless system because of its more capabilities. But it has various disadvantages like line frequency interference and signal loss,. Currently there is usage of RF in healthcare environment and medical test centre which have dangerous for the health of the patients. So we are in need of alternative eco-friendly source of communication in health care. So the alternative way is proposed here is the VLC (Visible Light Communication) transmission technology that uses white LED for data transmission which has efficiency, reliability and high precision. The ADC produces data stream of EEG signal which is modulated using OOK .Here LED works as a transmitter and photodiode with sensor works as receiver and uses computer simulation for further evaluation.
