Each patient receiving services at an Intermountain Heath Care facility is assigned a unique patient identifier called an EMMI Number (Enterprise Master Member Index). An EMMI number is assigned to and identifies a single patient throughout the enterprise, at any of IHCÕs Hospitals, InstaCares or Clinics .

This is an important part of IHCÕs regional PACS approach as it provides a database key that uniquely identifies patients within our regional and enterprise PACS systems.

Validation

The unique IHC EMMI Number and the site specific accession number, along with other patient demographics, are sent to the PACS broker and are used to validate studies as they arrive in the PACS system from the modalities. Validation occurs when studies are matched to an order (accession number) that is also matched to a single patient using the EMMI number. Validation fails if these numbers donÕt match the patient and the exam ordered.
