On the ambiguity of Quality of Service and Quality of Experience requirements for eHealth services

Abstract

The use of end-to-end communication systems as a medium of delivery for electronic healthcare (eHealth) services is considered to be uncertain, with respect to its reliability leading to hesitation in acceptance of such services. There exist different influential dimensions that pose stringent requirements on end-to-end communication systems, influence user perception and might hinder user acceptance. The later is referred to as Quality of Experience (QoE), which among others depends on the Quality of Service (QoS) of the end-to-end communication system. QoE is considered as a key component determining user acceptance. This paper identifies and analyzes characteristics of a set of eHealth services and the influential dimensions resulting in different QoS requirements and potential impact of QoS on QoE. It highlights the role of QoS and QoE for acceptance of these services. The issue of non-uniform views regarding QoS parameter specifications and related requirements, clinically acceptable thresholds and their qualitative representation in eHealth literature is reviewed and presented

Preparing Wi-Fi Networks for Novel Services in Smart Infrastructure

“…Delay in each form can affect communication performance and particularly user perception of a service quality. For example, the delay can significantly affect ehealth applications such as telesurgery, telemonitoring [17] or tactile Internet applications such as augmented reality or machine control operations, which have zero delay requirement [2]. Nevertheless, Wi-Fi is the weakest link in an end-to-end communication that can cause a high delay in the network.…”

Framework for Future Telemedicine Planning and Infrastructure using 5G Technology

“…• Connectivity issues with real-time and bandwidth problems and by this access in case of medical images or transfer of big data in telesurgery creating hindrance due to end to end latency. Latency beyond 200ms effects surgeons and it is difficult for surgeons to operate [34]. Intelligent medical team with having the realization of patient condition and technological infrastructure of the area is critical.…”

Towards Evaluating the Quality of Experience of Remote Patient Monitoring Services

“…Only limited previous efforts have been made to categorize QoE IFs in the context of e-Health services. Ullah et al (2012) provide a high-level classification, identifying QoE IFs as belonging to the following categories: Application Area (e.g., telesurgery, telemedicine), Application Purpose (clinical, non-clinical), Content Type (e.g., image, video, ECG), and Context of Use (e.g., social, task, indoor, mobile, fixed, emergency). To the best of our knowledge, no fur-EVALUATING QOE OF RPM SERVICES: CONSIDERING USABILITY ASPECTS 16 ther detailed classification has been proposed specifically for RPM services.…”
