EMPI for Enterprise EHR

An EMPI is Essential for a Single EHR Strategy

This large East Coast academic institution comprises several campuses across a major metropolitan area, spanning three states and serving nearly 1.5 million outpatients and 50,000 inpatients annually. Even though they selected a single EHR, the organization had more than 10 registration systems, each with unique patient identifiers and provider directories across locations.

Despite this single EHR approach, the organization needed to transcend their remaining EHR silos to create a solid foundation for patient engagement and population health initiatives.

An innovative EMPI provided the answer, connecting the various systems to maintain superior data quality, integrate with external data, and enhance patient engagement.  The organization deployed IMT Master:ID to create a future-ready platform that will drive better clinical outcomes as the technology stack continues to evolve.


SUPERIOR DATA QUALITY – The enterprise manages 9+ million records for 5.7 million unique patients, with a significant reduction in duplicates created in the EHR. The organization now reports an average duplicate rate of just 1.83%, with some EHRs as low as 0.04%.

ENHANCED ENTERPRISE EHRS – The EHR benefits from more effective and efficient data stewardship that enhances data quality and integrity by using machine learning for data stewardship and intelligent record matching.

IMPROVED CLINICIAN WORKFLOW – Clinicians see a complete view of all patient encounters across all remaining silos under a single enterprise record, regardless of location.

INCREASED PATIENT RETENTION – Patients receive more collaborative care, improving their entire experience and providing benefits to seek in-network care.

MORE AGILITY TO EVOLVE – An EMPI underpins the data needed for ever-changing business and strategic initiatives, enabling the agility to address market and consumer demands.


Each month, Master:ID manages at-risk contracts by comparing 12 unique third-party beneficiary rosters with existing patient data.

Without Master:ID, the EHR would only identify about half of the applicable population. That would create 50,000 potential duplicates each month – requiring costly, time-intensive manual review.

When data stewards are unable to keep up with task volumes of this size, duplicates are used and further propagated through the EHR. As more clinical and financial records are attached to those duplicates, merging the records later becomes much more complex and in some cases, impossible.

Timely matching of these rosters protects downstream data and provides cost-effective care management that enables quality measures and better consumer engagement. Using Master:ID required a small one-time fee and now saves the organization an average of $150,000 each month compared to the alternatives.


This healthcare organization recognizes the benefits of a foundational EMPI as they transition to a single EHR approach. The EMPI seamlessly integrates people, processes, and technologies, and creates a backbone for future mergers and acquisitions, regional partnerships, consumer portals, and more.

The institution can better identify
patients for clinical trials and
aggregate data for populationbased
research initiatives.

Using next generation tools
such as IBM Entity Insight, the
institution can leverage social
determinant data to better serve
the patient community.

The institution plans to enhance
its digital front door while
integrating machine learning
and technologies such as
patient wearables.

How Master:ID works:

  • Creates an enterprise view of patients to streamline the EHR’s initial load of current and historical data
  • Administers the enterprise ID to serve as the foundation for the single-platform EHR interoperability and engagement
  • Autolinks legacy records through a precise matching algorithm with optimized thresholds, eliminating manual handling for a secure and complete result

The result:

  • Single EHR contains comprehensive patient data without data loss or record mismatch resulting from system conversion
  • Standardized data stewardship processes eliminate future duplicates from propagating in the EHR and stewards review only exceptions for efficiency and confidence
  • Organization can truly activate the data to improve care across the healthcare spectrum with confidence in EHR’s patient records

Transforming healthcare starts with a delivery system based on caring, regardless of location. The Master ID platform offers a single trusted view of each patient to enable collaborative care that improves outcomes, no matter where a patient is seen.
