Extending The Enterprise ID with IMT Threshold Analysis™

AdventHealth’s promise is to help people feel whole: body, mind and spirit. This whole-person approach to health care ensures that patients get the care they need, regardless of where they are treated with health care services offered in almost a dozen states.

That’s why AdventHealth engaged IMT to deploy enterprise master patient index technology in 2014 and has now extended this deployment to ensure enterprise consumer-centric data supports AdventHealth’s mission.

As AdventHealth’s patient population continues to grow, integrating new patient identity sources came with challenges, including variations in the completeness and quality of source data. This presented the opportunity to re-evaluate thresholds for optimum efficiency and accuracy to better identify twin and trauma patients.

AdventHealth turned to IMT to conduct a Threshold Analysis™ review to finetune the EMPI’s automated patient record matching and linking to reduce the task load and rapidly accommodate new data sources. This is empowering AdventHealth to expand the patient portal to accelerate consumer engagement and support the organization’s mission.

“The Enterprise Master Person Index has been invaluable in linking our various computer applications together to ensure all person data is matched across our enterprise. It is the heart of our patient portal which allows patients to locate all their information regardless of which system it is in. We are taking the EMPI to the next level with our Active EMPI/Golden Record project to allow us to quickly share person demographic updates throughout our systems.”

With the enterprise identifier (EID) created by the EMPI connecting all source-level data through IBM InfoSphere Master Data Management, AdventHealth creates a single view of the patient.
small red arrow This single view allows patients to simply confirm the accuracy of their data rather than needing to repeat it, which streamlines care and improves satisfaction. Patients managing chronic conditions at multiple care delivery sites appreciate this simplicity and are encouraged that their provider does indeed “Know Me.”
small red arrow The resulting single, connected view of patient data allows registration staff to quickly update and propagate any changes throughout the system with just a couple of clicks. That means clinicians can see the most current, accurate enterprise-wide data that underpins patient safety, consumer engagement, and cost-effective care and wellness services.
small red arrow Threshold Analysis™ goes one step further to assess auto-link and clerical review thresholds to reduce the rates of false positives and false negatives. This increases AdventHealth’s confidence in sharing data with multiple departments within its own network and more broadly with regional HIE initiatives.

With AdventHealth growing to better serve its communities over the past decade, the tech stack now includes 15 EMR versions, including 3 Cerner and 4 Athena, plus long-term care and home care systems. The active EMPI propagates the EID to these systems, as well as a patient portal and the State of Florida Health Information Exchange. The Active EMPI project will expand the number of systems which both contribute and consume EMPI data.

The recent Threshold Analysis™ means that AdventHealth now experiences:

  • Lower data stewardship costs, thanks to a finely tuned
    algorithm that can uncover more duplicates or records
    that may have been erroneously linked during the
    registration process. As a result, the data can be
    confidently used for population health, analytics,
    business intelligence, and other initiatives.
  • A 60% reduction in tasks volume to a much more
    manageable load that requires less staff time. This
    translates into more accurate data presented via the EID.
    More records are now grouped together to provide a
    comprehensive view of all patient encounters.
  • Boosted patient confidence, as patients now see all their
    data and records in a single place when they log in to the
    patient portal. Caregivers are similarly more confident in
    understanding their patients’ full histories.
  • Decreased exposure to data breaches, as only correctly
    linked records are made available to the patient and
    caregivers. Safeguarding patient privacy and avoiding data
    breaches is essential, as fines for HIPAA data breaches
    can range from $100 to $50,000 per record with a
    maximum penalty of up to $1.5 million per year for each
    violation. These fines are only part of the cost and don’t
    reflect the internal costs to investigate a breach, nor the
    potential reputational harm.
  • Minimized duplicate testing as a result of records being
    linked with the latest results available to support clinical
    care. Studies show that 15 to 30% of all outpatient tests
    are repeated due to a lack of access to the previous
    test results, and 20% of all hospital radiology tests are
    duplicates, wasting $20 billion each year.

How it works

IMT Threshold Analysis™ uses advanced, proprietary statistical
techniques to evaluate auto-link and clerical review thresholds.
Through the user-friendly Pair Viewer interface, technical
and business teams can efficiently and securely evaluate matched
records between existing weights and newly regenerated weights.
The results of these decisions are then applied to recommend new
thresholds that support the corporate vision and strategies.

IMT Threshold Analysis™ can also be used to proactively
perform impact assessment on introducing new data
to the EMPI, and to modify filters and algorithms to
mitigate possible false positive scenarios related to twins
and other household members with similar names.

The Results

AdventHealth is poised to integrate more data elements, particularly as it expands the patient portal and digital front door strategy. Threshold Analysis™ can assess the potential impact of introducing new attributes or sources into the system. But most importantly, the EMPI and EID are furthering AdventHealth’s mission to extend the healing ministry of Christ, bolstering lifelong patient relationships with whole-person care to meet physical, mental, and spiritual needs.
