OpenEMPIAn Open Source Enterprise Master Patient Index Odysseas Pentakalos, Ph.D. SYSNET International Inc.
Background • Extracted from the Santa Barbara Care Date Exchange • Version 1.0 consisted of an EMPI and the basis for a Record Locator Service-based exchange • Various limitation in 1.0 including hard-coded deterministic matching algorithm and inefficient data model • Verson 2.0 is a complete rewrite resolving the key issues of version 1.0
Architecture • SOA-based architecture with extensibility and performance being the key requirements • Provides pluggable model for: • Matching algorithms • Blocking algorithms • String matching algorithms • Currently includes 2 matching algorithms (both are highly configurable) • Deterministic • Probabilistic • A rule-based matching algorithms is in the works
Current Work • OpenEMPI provides common registry and Record Locator Services for a federation of OpenMRS instances (Google Summer of Code project) • OpenEMPI is being incorporated into the Connect Framework (Federal Health Architecture)
