PA Interdependent Registries

Introduction

The primary implementer of the HL7 V3 role-based registries appears to be Canada. Canada has production implementations of Client (AKA Patient) and Provider registries. At the May 2010 Working Group Meeting Ron Parker of Canada Infoway gave a presentation to the Patient Administration work group addressing lessons learned and future architectural plans for Canada. See Ron's presentation in the 20100517_PA_WMG_Attachements.zip file.

The most significant finding is that real world applications require that different types of registries work together. The challenge for Patient Administration is to define interactions that span a number of topics:

• Person topic (DSTU in Patient Administration domain)
• Patient topic (DSTU in Patient Administration domain)
• Service Delivery Location (DSTU in Patient Administration domain)
• Provider topic (Normative R1 in Personnel Management domain)
• Organization topic (Normative R1 in Personnel Management domain)

Also, the Canadian Notional Architecture includes two additional registries for which a standard has not been defined. It seems possible that these additional registries would fall under the scope of a work group other than Patient Administration. Defining interactions that would also include these registries could present a technical challenge.
