New Zealand health software developer Orion Health will deliver its Healthcare Enterprise Service bus interoperability service to Singapore's lead health technology agency in a new five-year deal.

Singapore's Integrated Health Information Systems (IHiS) opted for Orion's integration engine, Rhapsody, to deliver the interoperability services and infrastructure for public hospitals using the National Electronic Health Record of Singapore.

The project will commence immediately, and contribute to the company's outlook for the 2018 financial year.

Orion Health won the Singapore deal following a competitive tender, with the project designed to improve how systems across the health system in Singapore integrate and communicate with each other.
