The big news in health IT this week was the proposed sale of EMR vendor Allscripts’ hospital assets to Harris Computer, a subsidiary of Canadian software company Constellation Software. Harris has been buying up a few interesting companies recently, including Sydney-based obstetric and maternity software developer Meridian Health Informatics.

Meridian’s software is used by NSW Health, Queensland Health and Tasmania’s Department of Health, and Harris also added in the UK’s K2 Medical Systems to the mix last year, with a view perhaps to hoovering up the hospital-based maternity market. But Allscripts is a much bigger kettle of fish, with EMRs implemented around the world and a healthy enough listing on the NASDAQ index.
