New Disease Surveillance System Based on SOA
05/20/2009
InterSystems Corporation announced that Partners HealthCare Systems has gone live at Massachusetts General Hospital with an application that helps the Massachusetts Department of Public Health (MDPH) reduce the risk of major outbreaks of communicable diseases. The high-volume system, which is built on the InterSystems Ensemble rapid integration and development platform, is processing more than 91 million HL7 messages annually.

Boston-based Partners HealthCare is an integrated healthcare network that includes multiple major hospitals with more than 5,000 practicing physicians attending to four million outpatient visits and 160,000 admissions annually.
The new MDPH implementation at Massachusetts General, which will deliver disease information updates every eight hours, 7x24, is an addition to a broad portfolio of Partners HealthCare applications that are built on InterSystems software products.
"Massachusetts General participates in a disease surveillance system that is also processing transactions from Brigham & Women's Hospital, Newton-Wellesley Hospital and Faulkner Hospital," said Partners CTO Steve Flammini. With the addition of an estimated 85,000 messages per day coming from Massachusetts General, about 250,000 messages are flowing into the system's Ensemble hub on a daily basis.
"Based on input from our analysts, we added rules to the Ensemble engine that automatically search for data and test results associated with communicable diseases specified by the MDPH," Flammini explained. Only the relevant messages—about 80 each day after filtering with Ensemble—are then automatically sent to the MDPH for analysis of disease trends.
The benefit to the healthcare consumer is that the MDPH gets information that enables the agency to reduce the chance of major outbreaks of communicable diseases such as tuberculosis, encephalitis, meningitis, Lyme disease and sexually transmitted diseases. With this information, the MDPH can analyze disease patterns that can be an early warning of potential epidemics. "And, from Partners' perspective, there has been a major positive impact on analyst productivity as a result of implementing the Ensemble-based surveillance system," Flammini said.
Future plans call for increasing the number of hospitals connected to the disease surveillance system. Flammini noted that Partners' technologists rate Ensemble highly for ease of use, software reusability and the rapid performance needed to handle the system's large message volume.
"The possibility of a pandemic is one that no state or country can afford to ignore," said Paul Grabscheid, InterSystems Vice President of Strategic Planning. “Ensemble continues to be the integration platform of choice for public health initiatives because of its outstanding stability and its ability to handle high message volumes with ease. We appreciate the opportunity to work with Partners Healthcare on this public health reporting initiative—one that is critically important to every healthcare consumer."
InterSystems develops and markets integration, database, and business intelligence products. Ensemble is a high-performance software platform and advanced messaging engine that is used to develop and integrate mission-critical applications, leverage previous software investments through composite applications, and establish an enterprise service bus or SOA infrastructure. Ensemble-based projects are deployed in healthcare, commercial and government organizations worldwide to solve many demanding HL7 integration problems.
