HL7 Implementation Guide: Service-Oriented Architecture Implementations of the Context-aware Knowledge Retrieval (Infobutton) Domain, Release 1

DESCRIPTION

This implementation guide provides a service-oriented (SOA) specification for the Context-Aware Knowledge Retrieval (Infobutton) Standard. The specification is based on the RESTful (Representational State Transfer) software architecture style and uses the IETF ATOM content syndication standard as the basis for the knowledge response payload.

 

ALTERNATIVE NAMES

HL7 Implementation Guide: Service-Oriented Architecture Implementations of the Context-aware Knowledge Retrieval (Infobutton) Domain, Release 1 may also go by the following names or acronyms:

"HL7 V3 IG: Context-Aware Information Retrieval (Infobutton) Service-Oriented Architecture Implementation Guide, R1"

DEVELOPMENT BACKGROUND

Clinicians face numerous knowledge needs during the course of patient care and the majority of these needs are not met, compromising the quality of care. Likewise, in order to be partners in the decision making process, patients need to be well-informed about their health and health care options. Online health knowledge resources that are capable of solving clinicians’ and patients’ knowledge needs are now widely available, but a series of barriers hinder a more effective and frequent use of these resources to support decision-making. Context-aware knowledge retrieval into Clinical Information Systems (CIS) is an approach for delivering relevant clinical knowledge and patient education material to the point of care. These kinds of tools are known as Infobuttons.

 

To support the integration of knowledge resources into CISs, the Clinical Decision Support Work Group (CDS WG) has been developing a set of standard specifications. The first of these specifications, entitled Context-Aware Knowledge Retrieval, Knowledge Request Standard, is a normative ANSI/ISO HL7 standard. This specification provides a standard mechanism for Clinical Information Systems to submit knowledge requests to knowledge resources. In addition, a URL-based implementation guide was developed to specify knowledge request implementations using the HTTP protocol.  The present specification complements the previous ones by enabling the implementation of context-aware knowledge retrieval applications through a Service-Oriented Architecture (SOA) based on the RESTful (Representational State Transfer) software architecture style.
