DISI CDR Architecture
There is a need for countries to centralize and report on data that is captured at the point of service systems to effectively measure and monitor the progression and outcome of HIV through CBS sentinel events. Commonly this is done ad hoc per country. DISI refers to the practice of centralizing and integrating HIV case-based surveillance data in a central repository for further reporting, analysis, and visualization. DISI proposes to create a standards-based architecture that would allow multiple countries to adopt a similar framework for generating the reports that they require. This would drive the re-use of components and allow countries to rapidly make progress based on what others have done before.
In this document, the components of the DISI CDR architecture are described conceptually. It will also describe how countries, which could be at different stages of their data integration journey, could begin to adopt this common DISI architecture. A logical architecture is also provided which provides one possible implementation of the conceptual architecture.
It should also be noted that this architecture is not specific to HIV case-based surveillance. It is generic and may be applied to multiple domains of care and could provide a common platform for data centralization in general.
To define the current state of the proposed architecture for the DISI (Data Integration strategies and implementation) workstream. This document will focus on describing the conceptual architecture based on the results of our findings after exploring different approaches. It will describe the current thinking for what works best.
