OBJECTIVE To report on the use of SGML and XML (a proper subset of SGML) as transfer syntaxes for HL7 Version 2.3 and Version 3.0 messages. METHODS The methodology has focused largely on two questions: Can it be done? How best to do it? The first question is addressed by attempting to build an SGML/XML representation of HL7 messages. The second question requires a consideration of several met...

Diagnostic reports. A radiologist at a PACS workstation needs ready access to prior reports. In most situations, reports are initially pushed to the RIS by the SR application, usually via an HL7 interface. If prior reports are stored in the RIS, how can they be available when a radiologist needs to look at them, for example, when reviewing a follow-up exam? T Most RIS systems cannot be queried ...

Messaging standards, and specifically HL7 v2, are heavily used for the communication and interoperability of Health Information Systems. HL7 FHIR was created as an evolution of the messaging standards to achieve semantic interoperability. FHIR is somehow similar to other approaches like the dual model methodology as both are based on the precise modeling of clinical information. In this paper, ...

Sometimes, we may want to modify, or just read (in a computer program) specific parts of a message received (as a stream of bytes) from a communications port or of data read (also as a stream of bytes) from a flat file. What would be convenient for this is a kind of API to locate any component of a message in order to modify or read it. Such an API could also be used to construct an entire mess...

Good physical fitness generally makes the body less prone to common diseases. A personalized exercise plan that promotes a balanced approach to fitness helps promotes fitness, while inappropriate forms of exercise can have adverse consequences for health. This paper aims to develop an ontology-driven knowledge-based system for generating custom-designed exercise plans based on a user's profile ...

Objectives: Many groups are developing computer-interpretable clinical guidelines (CIGs) for use during clinical encounters. CIGs use “Task-Network Models” for representation but differ in their approaches to addressing particular modeling challenges. We have studied similarities and differences between CIGs in order to identify issues that must be resolved before a consensus on a set of common...

This study's objective is to develop and use a scalable genuine technology platform for clinical decision support based on Arden Syntax, which was extended by fuzzy set theory and fuzzy logic. Arden Syntax is a widely recognized formal language for representing clinical and scientific knowledge in an executable format, and is maintained by Health Level Seven (HL7) International and approved by ...

Object-oriented technology is having a significant impact on the analysis and programming techniques used in information systems. The same concepts are also providing the basis for standardizing interfaces among applications and components thereof. These specifications exist at both the conceptual level and in terms of the detailed level of specificity needed for "plug and play" cooperation. Th...

The requirements of highly specialized clinical domains are often underrepresented in hospital information systems (HIS). Common consequences are that documentation remains to be paper-based or external systems with insufficient HIS integration are used. This paper presents a solution to overcome this deficiency in the form of a generic framework based on the HL7 Clinical Document Architecture....

UNLABELLED The Clinical Data Ware House needs to meet three functions: reporting quality indicators, clinical research, and continuity of care. This paper reports on one function, namely the development and testing of data exchange for continuity of nursing care for oncology patients. The proof of principle was carried out using system analysis, requirements setting, system design, system devel...
