IDG News Service — When fears over the swine flu first broke out in many parts of the world in April, El Camino Hospital in Mountain View, California, was about to pull the trigger on an implementation of Microsoft's Amalga software.

Plans changed slightly, however, when hospital officials realized they might possibly have a flu pandemic on their hands, said Dr. Michael Gallagher, director of business intelligence and outcomes for El Camino.

The hospital did implement Amalga as planned, but with an addition to it designed to track patients that came to the hospital with flu-like symptoms -- as well as anyone else who may have been in contact with them in the emergency department, he said.

"We had to know who was exposed, how to track these patients," he said. "Because the Amalga system was extremely flexible, we put together a new application for tracking patients as they showed up in our emergency department."

Amalga is Microsoft's e-health aggregation software that helps health-care institutions like hospitals and other health-care service providers by capturing and storing patient and other information from disparate systems and presenting it in one place.

It took only three hours from concept to deployment to create the tracking software using Amalga, said Steve Shihadeh, vice president of the Microsoft Health Solutions Group.

While El Camino took the lead in conceptualizing, creating and implementing the tool, Microsoft showed them how it could be done through a feature of Amalga called User-Self Service, he said, which allows people to create a new application very quickly by re-using data aggregated by Amalga, he said.

Gallagher said it took some rethinking to get the new application in place. El Camino had designed its Amalga implementation to track inpatient units of the hospital, but the emergency department (ED) is an outpatient facility.

"We had to come up with a way to get information about ED patients and to keep track of them as a large group," he said. It was not hard to do in Amalga, however, because it allows users to query information based on links between the data, using commands such as "find me everybody who has had three heart attacks," Gallagher said.

Though there are other e-health platforms in the industry -- Eclipsys (formerly MediNotes) among them -- Amalga's ability to pull so much information from the many disparate systems found in a typical medical database is "amazing," as other systems tend to treat "each individual as sort of a separate encounter" rather than seeing the relationship between the data, he added.
