PQRI-QRDA MODULE DEVELOPMENT
Executive Summary
One of our EMR clients approached us to setup a bidirectional interface from their EMR with Quest Diagnostics®, the world’s leader in diagnostic laboratory testing, information, and services. The client had a very tight deadline in mind and also this was of primary importance to get their business expanded. This case study describes the successful implementation of a solution to meet this requirement.
About our Client
Client Description: A leading EMR Company
Client Location: Kansas, USA
Industry: Healthcare
Business Situation
Our client, a leading EMR vendor in the USA, wanted to integrate with Quest Diagnostics. The interface would have to be a bi-directional one. The orders for tests would be sent electronically from within the EMR application and the results would also be received electronically. The key challenges included:
The EMR in question is a web based Service oriented one. So there are many tenants and the Quest interface should be easy to switch on/off at individual tenant level.
The interface should work seamlessly without too many modifications to the existing Lab Interface system of the client.
Quest has many Business Units (BU) spread across the United States and individual tenants would have their own preference on the Business Unit to interface with.
Each BU will have its own set of master lookup values of lab tests (the compendium) and the set would differ from one BU to another.
The interface should be able to handle 1000s of simultaneous requests.
The EMR application being a web based system, the new program should be developed in such a way that it should reside in one place (our client’s data centre) and meet all the challenges listed above.
Achievements
The full implementation was done in record time, enabling our client to successfully establish Bi-Directional interfacing with Quest, Passed around 120 test cases (given and tested by Quest Diagnostics) that are tough, tests the system to the core.
Takes 5 – 10 minutes to enable the interface for a new tenant/clinic and 2 minutes to disable the same for a clinic, Full control of the interface with our client/our developers. So easier to maintain.
