In some previous posts to the rules-users mailing list Mark Proctor has asked for real world examples: Drools. write up examples based on your work? So please, please, please, please take the >>time to help us here. Capability event. I will be presenting a case study entitled "Speed Saves Lives: Leveraging a massively parallel expert system for patient surveillance" about the use of Drools and GigaSpaces at the 2011 Business Rules Forum Conference October 30 - November 3. Abstract: Pharmacy OneSource is a SaaS provider of applications for hospital pharmacy and infection prevention professionals. This case study will discuss the steps taken to develop a next-generation patient surveillance platform that allows clinicians to accurately detect risk factors, and perform interventions. The platform leverages the GigaSpaces implementation of Tuple-space and the Drools rule engine to create a massively parallel expert system. This architecture allows for customizable handling of millions of HL7 messages per day, evaluation of thousands of clinician created business rules, and reasoning over hundreds of thousands of patient data facts to provide near-real-time surveillance. The presentation will attempt to cover challenges, design decisions, and technology choices, ROI for the project and the platform, both internally and externally, as well as lessons learned from adopting business rules in the development process.
