This document has been developed by the Expert Group for Healthcare within the European Workshop for Open Systems (EWOS/EG MED). The editor of the document is Dr A J Kerr of Level-7 Ltd,

Special appreciation is expressed to Jeremy Tucker, who has provided liaison with the ISO/IEC JTC/1 QoS Group and provided much of the text for Clause 9. CEN/TR 1
15、5253:20054 Introduction Background This report considers user requirements for Quality of Service (QoS) specifically in the healthcare Information Technology (IT) environment. QoS is defined in 4 as: ”A set of qualities related to the collective behaviour of one or more objects.” Thus the definition
16、 is very broad, even when restricted to the healthcare IT environment. CR 12161 (EWOS/ETG 021): ”A Method for Defining Profiles for Health Care” 7 deals with the general categorisation of user requirements for healthcare information interchange. It assesses the suitability of profiles of standards f
17、rom the domains of Open Systems Interconnection / Open Systems Environment (OSI/OSE) to satisfy those user requirements. The method defined in CR 12161 was subsequently applied (by EWOS project team PT N024) to the specific domain of medical image interchange, and the findings were recorded in CR 12
18、069 (EWOS/ETG 045): ”Profiles for Medical Image Interchange” 8. In performing this work, a number of requirements were identified which could not adequately be mapped to the services provided by standardised OSI profiles. Some of these requirements could be considered as QoS issues. With this in min
19、d, the Healthcare Expert Group of the European Workshop for Open Systems (EWOS/EG MED) initiated a work item in May 1995 to identify QoS requirements for healthcare information interchange which need to be supported by standardised communications services. This report is the result of that activity.
20、 At the same time, international IT standards have been under development (by ISO/IEC JTC1/SC21 and ITU-T SG7) to define a QoS Framework 2 of terminology and concepts, in order to assist those wishing to specify or procure systems in which QoS is important, and to publish a Guide to QoS Methods and
21、Mechanisms 3, which is intended to be a source-book of references and widely-applicable mechanisms that can be used by systems designers and implementors. The scope of the activity is all forms of interaction between elements of distributed systems. The QoS work in ISO has been applied to the develo
22、pment of time-critical communications and to enhanced communications transport service and protocol (ECTS it includes the QoS requirements of information storage and processing IT systems. The related areas of security and financial cost considerations are not within the primary scope of the documen
23、t, although they are considered briefly. Of course, an informatics system with a high QoS does not guarantee a high standard of healthcare in terms of clinical outcomes or patient care. The quality of healthcare delivered to patients (the ultimate ”users”) depends upon a number of external factors s
24、uch as the experience and competence of the healthcare professional(s) or institution(s) involved. Potential QoS characteristics for the total healthcare delivery process such as mortality rate, clinical outcome, etc. are therefore not within the scope of this report.
