NHS trusts in Leeds and York are the first to adopt a new iSoft solution to connect their pathology systems so requests and test results are exchanged electronically, preventing errors and delays.
The new deals are with Leeds Teaching Hospitals NHS Trust and York Teaching Hospital NHS Foundation Trust.
Processing 3 million sample requests a year, the pathology department at Leeds is one of the UK's largest and provides services to other NHS trusts under national and regional agreements.
It conducts 200,000 routine pathology tests a year for York.
iSoft's new service replaces a paper-and-post process of exchanging requests and results, so cuts delays but also eliminates the risk of mix-ups and results being lost.
Based on iSoft's Viaduct integration tool, the new service is a centrally hosted web application for connecting laboratory information systems.
The service is aimed initially at the 150 UK customers for iSoft lab systems but is open to others.
The immediate aim is to sign up other NHS trusts that have agreements with Leeds.
Both Leeds and York have used iSoft's laboratory solutions for over 15 years.
