Unlock a Complete View of the Entire Patient Journey

In healthcare, understanding a patient’s whole story is paramount to conducting impactful research, making the right diagnosis, and securing health equity for people and communities. That means having the ability to see all the factors that influence a person’s healthcare journey and entire life — from family health history and risk factors to education, income, and community connections.

LexisNexis® Gravitas™️ combines access to a comprehensive data network with powerful, next-generation technology which can be used to generate complete longitudinal views of virtually any person’s journey, fully de-identified and research-ready1 — unlocking the power of real-world data (RWD) for healthcare.

1) Based on expert determination that the Gravitas Token and each Gravitas Core dataset meet the HIPAA de-identification requirements of the HIPAA Privacy Rule as set out in 45 CFR § 164.514(b)(1).


The Next-Generation Healthcare Tokenization
LexisNexis® Gravitas™️

The power of real-world data (RWD) to enrich complete, longitudinal patient journeys represents a promise in healthcare. Today, only 20% of health outcomes can be attributed to medical care decisions. When paired with precise matching, real-world data has the potential to reveal whole-person journeys and to revolutionize what healthcare and clinical research can achieve.

This is where LexisNexis® Gravitas™ brings together industry-leading healthcare data with next-generation tokenization to drive insights and discoveries that will help all people achieve what we all deserve — better health.

Built on proprietary datasets from LexisNexis® Risk Solutions and high-quality data from our network partners, including near real-time clinical data from Truveta, the Gravitas™️ solution consists of three components: Gravitas™ Core, award-winning Gravitas™ Token, and Gravitas™ Network.


Gravitas Core

Gravitas Core

Gravitas Core is a comprehensive collection of high-quality datasets covering the U.S. adult population. Our Gravitas Core data currently includes clinically validated social determinants of health (SDoH), medical claims, and mortality data.

Gravitas Token

Gravitas Token

The Gravitas Token securely de-identifies datasets and uses its Referential Data Layer to perform linking and matching with unparalleled precision.

Gravitas Network

Gravitas Network

The Gravitas Network brings the vast data resources of Gravitas Core together with fully interoperable, high- quality data sources from trusted data partners to allow you to create even more precise and more complete, longitudinal views of patient journeys.


The Power of Next-Generation Tokenization

Current Gravitas Core and Gravitas Network datasets include:

  • Clinical patient data for more than 16%2 of U.S. adults
  • Commercial medical insurance claims data for more than 50% of the U.S.
  • Claims data for close to 40% of Medicare and Medicaid patients
  • The largest collection of SDoH data available — highly precise and covering nearly all U.S. adults with clinically validated attributes
  • Multi-sourced, low-latency mortality data

Healthcare organizations can have confidence in the improved precision and security of Gravitas data linking and de-identified matching — as well as the insights it uncovers and decision-making it informs.

2) Derived from a leading network partner.

Referential Data Layer

What makes Gravitas next-generation tokenization technology? Gravitas Token uses referential matching to match datasets from Gravitas Core, Gravitas Network, and customer inputs behind a trusted third-party firewall against a Referential Data Layer.

Where first-generation tokenization struggles to account for factors such as address or name changes, Gravitas uses referential matching to identify missed or mismatched records with more precision and confidence.

3) The linking of any additional dataset that is not reasonably available to the Gravitas Token or Gravitas Core datasets requires independent expert determination of HIPAA compliance. Access to and use of regulated data is limited to use for a permissible purpose and subject to completion of the LexisNexis Risk Solution credentialing process.
