CDC Upgrading IT to Gather Data From Hundreds of Hospitals

Computerworld - The Centers for Disease Control and Prevention has quietly begun working with 31 hospitals in 10 large cities to create a system that can send real-time data feeds from emergency rooms to the CDC.
The program, which aims to help officials prepare for and respond to a pandemic of avian flu or a bioterrorist attack, will add 350 hospitals to the list this year.
To support the program, the Atlanta-based federal agency has been scrambling to upgrade its IT infrastructure so it's capable of receiving and analyzing the massive influx of data.
At this point, the CDC's systems are about a month away from being able to analyze incoming data from the initial 31 private hospitals during a catastrophic event, said Barry Rhodes, associate director for technology and informatics in the Division of Emergency Preparedness and Response at the CDC's National Center for Public Health Informatics.
"The amount and rate of data streams to CDC is really unprecedented [compared with] what we have done in the past," he said.
As part of the IT upgrade, the CDC is building a real-time data warehouse that will support 20TB to 30TB of data over the next 12 to 18 months, Rhodes said.

The developers are using extract, transform and load tools from Informatica Corp. to send data to the warehouse. They're also using business intelligence and data mining tools from SAS Institute Inc. to analyze the information coming from the hospitals.
The hospitals are sending the data¿including patient symptoms, diagnoses and geographic information¿to the CDC over the Internet as Web services messages using the ebXML standard to guarantee reliability and secure the exchange of the messages.
Beth Israel Deaconess Medical Center in Boston began sending feeds to the CDC on Dec. 21, about a month after the agency asked it to join the program, said John Halamka, CIO at the hospital's parent company, CareGroup Healthcare System. The hospital now sends the data to the CDC as Web services every 15 minutes, he said.

"This is really the first time in history there have been real-time hospital connections to public health [agencies]," said Halamka, who's also a Computerworld columnist. Beth Israel spent $50,000 to build its piece of the system, he added.
The CDC expects the emergency room data to provide it with "situational awareness" during a pandemic or bioterrorist attack, Rhodes said. "It is very important that we have information from hospitals on a real-time or near-real-time basis so we can get a snapshot of what
