Microsoft Amalga Unified Intelligence System (formerly known as Azyxxi) was a unified health enterprise platform designed to retrieve and display patient information from many sources, including scanned documents, electrocardiograms, X-rays, MRI scans and other medical imaging procedures, lab results, dictated reports of surgery, as well as patient demographics and contact information.

As of February 2013, Microsoft Amalga was part of a number of health-related products spun-off into a joint-venture with GE Healthcare called Caradigm.

[3] Amalga was used to tie together many unrelated medical systems using a wide variety of data types in order to provide an immediate, updated composite portrait of the patient's healthcare history.

[4] A physician using Amalga could obtain within seconds a patient's past and present hospital records, medication and allergy lists, lab studies, and views of relevant X-rays, CT Scans, and other clips and images, all organized into one customized format to highlight the most critical information for that user.

It was also used by the District of Columbia Department of Health for management of such mass-casualty incidents as a bioterrorism attack and in a variety of other settings in Arizona, Maryland, and Virginia.

At the time of acquisition, Microsoft hired Dr. Craig F. Feied, principal designer of the software, and 40 members of the development team at Washington Hospital Center.
