OpenEMPI
OpenEMPI links duplicate records into trusted master records through entity resolution and record deduplication.
What OpenEMPI is
OpenEMPI links duplicate records into trusted master records through entity resolution and record deduplication. It supports patient, provider, customer, business, and other record types with a customizable, domain-agnostic data model. Matching methods include deterministic, probabilistic, and artificial intelligence-based approaches in a configurable pipeline, with metrics such as Jaro–Winkler, Levenshtein, Soundex, and Double Metaphone. Processing can be real-time or batch. Uncertain candidate matches can be reviewed in a queue with confidence scores, merge or reject controls, and an audit trail. Integration options include a RESTful API, webhooks, HL7 v2/v3, and FHIR. The web Administrative Console is used to configure and manage an instance, and the documentation covers deployment on Unix/Linux and Windows. OpenEMPI audits server requests and stores them in a database. It is available for API, Linux, self-hosted, web, and Windows use. Pricing is on request, and there is no free plan. The company offers commercial support and SLAs; licensed customers can access private support resources and custom modules.
