EMPI in Healthcare Experts

It’s not easy to understand the blend of patient, physician, consumer and payer information that big data in healthcare is comprised of, but leveraging its value creates a holistic, 360-degree view that can have significant impact on the bottom line.

By utilizing healthcare interoperability to connect patient health records with multiple third-party sources of information to create one accurate master patient index, it’s suddenly possible to analyze decades of information accurately, and make actionable insights that pull maximum profit out of the new value-based care environment.

Big data in healthcare is a whole new world, and as the industry’s most experienced patient data experts, we help you make sense of it.

From accessing an accurate master patient data index (MPI) to seeing patterns, opportunities and gaps that need attention, to optimizing growth by improving personalized care that meets payer value-based requirements – 4medica helps you transform challenges into opportunities with our healthcare data management solutions.

Meet your perfect match for compiling and analyzing big data in healthcare. The 4medica EMPI is fast, accurate and brought to you by the industry’s most experienced patient data experts.

Referential Data Matching

Did you know 4medica does more than matching demographic data to a comprehensive and continuously updated reference database of identities instead of just comparing one record to another? We take referential data matching to the next level by incorporating Inverse Index technology pioneered by search engines and layers on modern non-SQL databases to further enhance simplifying the process. to ensure data integrity. Eliminate your duplicate medical records in milliseconds at a fraction of the cost.

Data Enrichment

Your initiatives are only as good as your master data management. The 4medica Big Data Identity Enrichment™ software makes your patient data more useful by connecting with multiple third-party sources to provide richer, more detailed information using current referential information coupled with historic demographic and geographic data that goes back decades. We easily match records in real time for powerfully accurate master patient data in seconds.

Data Assessment and Clean-up

For the initial assessment, we will load and score your data using the 4medica EMPI, which analyzes data quality to identify your real duplication rate. Then you’ll receive a report that outlines a phased-in approach to clean all data in your MPI. This report is yours to keep, whether or not you decide to have 4medica assist in cleansing your data to remove duplicates, or any of our ongoing MPI maintenance services.

Only 4medica offers a MPI clean-up service that guarantees a 1% duplication rate using its revolutionary and proven combination of MPI matching technology with automated intelligence and proprietary processes. Its skilled staff of data scientists provide data stewardship services foundational for data integrity.

Data Intelligence and Analytics

Uncover information including patterns, correlations and trends that can help you better inform business decisions. Dashboards allow insight into various metrics including all identities, master records, number of duplicates, number on the worklist, weekly manual merging and daily data source auto merging.

Virtual Data Stewards

Instead of hiring people onsite to validate information, our consultants regularly verify client data using best practices for scoring and can easily manage your work lists. We offer this data management service in a one-time engagement or on an ongoing basis to get your duplications down to zero.

Address Normalization

With the high volume of patients seen on a daily basis by healthcare providers, speedy and accurate data collection is essential. When patient records are cleansed and scrubbed with the right mailing or e-mail addresses, organizations will reduce the amount of returned mail and improve the timeliness of appointment reminders and other critical communications such as billing.
