Concept of Operations: Relating to the introduction of a Personally Controlled Electronic Health Record System

6.4.5 View Service

Purpose

The purpose of the View Service is to allow authorised users, individuals and their representatives to access a series of ‘views’ of an individual’s PCEHR. These views are intended to allow the underlying information within a PCEHR to be reassembled in different ways for different categories of users with different needs.

Functionality

The View Service will support the following functions:
  • Request View (The types of views to be supported by the PCEHR System are discussed in Section 4.4).
  • Update View Content (see below).
  • Execute quality functions to assess the integrity of the data.

Related standards and specifications

Interface specifications candidates include either:
  • IHE Retrieve Information for Display (RID) [IHE2010a] or
  • HL7 Retrieve, Locate and Update Service (RLUS) [HL72010a] (recommended).
Design note: In some cases the View Service will assemble views using information from the index or other services. For some kinds of views, such as the Index View, this approach is appropriate as such information can be readily requested from the Index Service. However, for other kinds of views, such as the Consolidated View, which have greater performance demands, it may be necessary to update the view as new information is added to the PCEHR System. It is likely that the View Service will need to maintain an atomic data store specifically for this purpose.

In the case of the Consolidated View, for example, when a new Shared Health Summary or Event Summary is loaded into the national repositories, the Consolidated View for that individual will need to be updated.

How this update will be supported will be defined by the national infrastructure partner. One possible process relies on the repository first updating the index, which in turn notifies the View Service that new information is available. The View Service then in turn pulls a copy of the new Shared Health Summary or Event Summary from the national repositories and uses that information to update the Consolidated View.

Figure 11: Conceptual diagram shows the interaction between some of the core PCEHR system services required when a Healthcare Provider opts to upload a ‘Shared Health Summary’ to the PCEHR system. The core PCEHR services include: ‘National Repositories’, ‘Participation and Authorisation’, ‘Index’ and View’ services. The diagram also shows the related non-PCEHR process where the Healthcare Provider consults with the individual and reviews summary information before uploading the ‘Shared Health Summary’ to the PCEHR system.
