Home Monitoring System for Comprehensive Geriatric Assessment in Patient's Dwelling: System Design and UX Evaluation

Population aging threatens the sustainability of welfare systems since it is not accompanied by an extended healthy and independent period in the last years of life. The Comprehensive Geriatric Assessment (CGA) has been shown to be efficient in maintaining the healthy period at the end of the life. Frailty monitoring is typically carried out for an average period of 6 months in clinical settings, while more regular monitoring could prevent the transition to disability. We present the design process of a system for frailty home monitoring based on an adapted CGA and the rationale behind its User eXperience (UX) design. The resulting home monitoring system consists of two devices based on ultrasound sensors, a weight scale, and a mobile application for managing the devices, administering CGA-related questionnaires, and providing alerts. Older users may encounter barriers in their usage of technology. For this reason, usability and acceptability are critical for health monitoring systems addressed to geriatric patients. In the design of our system, we have followed a user-centered process, involving geriatricians and older frail patients by means of co-creation methods. In the iterative process of design and usability testing, we have identified the most effective way of conducting the home-based CGA, not just by replicating the dialogue between the physician and the patient, but by adapting the design to the possibilities and limitations of mobile health for this segment of users. The usability evaluation, carried out with 14 older adults, has proved the feasibility of users older than 70 effectively using our monitoring system, additionally showing an intention over 80% for using the system. It has also provided some insights and recommendations for the design of mobile health systems for older users.

Voice Disorder Recognition and Analysis Using Knowledge Engineering Techniques

Nowadays, the use of mobile application is most important thing in the healthcare sector is increasing rapidly. Mobile technologies not only for communication for multimedia content (e.g. clinical audio-visual notes and medical records) but also promising solutions for people who desire the identification, monitoring, and treatment of their health conditions anywhere and at any time. Mobile E-healthcare systems can contribute to make patient care faster, better, and cheaper. Several pathological conditions can benefit from the use of mobile technologies. In this paper we focus on dysphonia, an alteration of the voice quality that affects about one person in three at least once in his/her lifetime. Voice disorders are rapidly spreading, although they are often underestimated. Mobile health systems can be an easy and fast support to voice pathology detection. The identification of an algorithm that discriminates between pathological and healthy voices with more accuracy is necessary to realize a valid and precise mobile health system. . This technique is evaluated by based on experimental results deep neural networks with machine learning approach to provide an accuracy of 99.89% in detecting voice. In this field to detect any abnormal structure and analysis without human intervention in health care sector to enhance the utility of well beginning system.

Using Co-Design in mHealth Systems Development: A Qualitative Study with Experts in Co-design and mHealth System Development (Preprint)

BACKGROUND The proliferation of mobile devices has enabled new ways of delivering health services through mobile health systems. Researchers and practitioners have emphasized that the design of such systems is a complex endeavor with various pitfalls, including limited stakeholder involvement in design processes and integration into existing system landscapes. Co-design is an approach to address these pitfalls. Despite a rich body of literature on co-design methodologies, limited research exists to guide the co-design of mHealth systems. OBJECTIVE The objectives of our study was to (1) contextualize an existing co-design framework to mHealth applications and (2) derive guidelines to address common challenges of co-designing mHealth systems. METHODS We conducted an exploratory qualitative study consisting of 16 semi-structured interviews with co-design method experts (8) and mHealth system developers (8). Data were analyzed using thematic analysis. RESULTS The contextualized framework captures important considerations of the mHealth context, including dedicated prototyping and implementation phases. Additionally, seven guidelines were developed: (1) specificity of targeted mHealth context, (2) immersion in mHealth context, (3) health behavior change, (4) co-design facilitators, (5) post-design advocates, (6) health-specific evaluation criteria, and (7) usage data and contextual research to understand impact. CONCLUSIONS System designers encounter unique challenges when engaging in mHealth development. We hope that the contextualized framework and guidelines will serve as a shared frame of reference to facilitate interdisciplinary collaboration at the nexus of information technology and health research.

Mobile Health (mHealth) in the Developing World: Two Decades of Progress or Retrogression

Mobile healthcare, or mHealth, is one of the key pillars of information and communication technologies for healthcare that consists of telemedicine, telehealth, eHealth, and mHealth. In the past two decades, mobile health has become a transformative concept for healthcare delivery innovations on a global scale. The success was based on the market-driven strategies that utilised the advances in mobile communications, computing, and sensor technologies, especially in recent years. Those market-driven mobile health systems were also closely associated with the global proliferation of smartphones, and based on the correlated usage principle of the smartphone applications for healthcare and wellbeing. However, the global commercial success of the smartphone-based mHealth model was not widely translated into successful scaled-up and tangible healthcare benefits, especially in low- and-middle income countries, compared to the consumer mobile health markets. The numerous healthcare challenges in the developing world remained largely untackled by the existing mobile health systems and models. The much-hyped transformative benefits of these systems remain largely unfulfilled. For two decades since the inception of this concept, the majority of the population in resource-limited healthcare settings still remain in poorer health and live in worsened conditions, with limited if any access to basic healthcare services. The much-hyped mobile health services that promised transforming these fragile and limited healthcare conditions, did not come to wider fruition globally. The COVID-19 pandemic, with its devastating human and economic impact worsened this status. An overview of the origin and the basic principles of mobile health, its current landscape and status in the developing world is presented. The impact of the smartphone-centric model that dominated the landscape of mobile health systems in these countries is discussed, and a critical view on the limitation of this mobile health model adopted widely in these settings is provided.

Wireless Body Area Networks: UWB Wearable Textile Antenna for Telemedicine and Mobile Health Systems

A compact textile ultra-wideband (UWB) antenna with an electrical dimension of 0.24λo × 0.24λo × 0.009λo with microstrip line feed at lower edge and a frequency of operation of 2.96 GHz is proposed for UWB application. The analytical investigation using circuit theory concepts and the cavity model of the antenna is presented to validate the design. The main contribution of this paper is to propose a wearable antenna with wide impedance bandwidth of 118.68 % (2.96–11.6 GHz) applicable for UWB range of 3.1 to 10.6 GHz. The results present a maximum gain of 5.47 dBi at 7.3 GHz frequency. Moreover, this antenna exhibits Omni and quasi-Omni radiation patterns at various frequencies (4 GHz, 7 GHz and 10 GHz) for short-distance communication. The cutting notch and slot on the patch, and its effect on the antenna impedance to increase performance through current distribution is also presented. The time-domain characteristic of the proposed antenna is also discussed for the analysis of the pulse distortion phenomena. A constant group delay less than 1 ns is obtained over the entire operating impedance bandwidth (2.96–11.6 GHz) of the textile antenna in both situations, i.e., side by side and front to front. Linear phase consideration is also presented for both situations, as well as configurations of reception and transmission. An assessment of the effects of bending and humidity has been demonstrated by placing the antenna on the human body. The specific absorption rate (SAR) value was tested to show the radiation effect on the human body, and it was found that its impact on the human body SAR value is 1.68 W/kg, which indicates the safer limit to avoid radiation effects. Therefore, the proposed method is promising for telemedicine and mobile health systems.
