A Responsibility to Care and Protect

Ongoing shifts in the healthcare industry continue to drive moves toward more data sharing between disparate data systems to positively impact patient outcomes, drug efficacy, precision medicine, treatment pathways and more. This increase in data sharing has created a need for accurate linking of patient records, as well as records beyond the clinical setting. Historically, healthcare tokenizationthere have been barriers that limit sharing of data and thus impact measurement of patient outcomes. This disconnect limits the longitudinal view of a patient, impacting the ability to understand differences in patient populations, or control for various risk factors in research populations.

Healthcare requires a high degree of precision and accuracy while maintaining high match rates and the ability to link records over time. In addition, expansion of Real-world data (RWD), Real-world evidence (RWE), focus on outcomes and efficacy, and shifts toward personalized medicine all impact a need for secure, de-identified patient data. Current data linking approaches that create matches only based on observed Personal Identifiable Information (PII) do not have intelligence beyond the available data, impacting the accuracy and completeness of data for analysis. Because of this need, LexisNexis Risk Solutions created a novel approach to data linking and deidentification by means of a Patient Centric Token, to help transform your organization and the healthcare industry.

The Patient Centric Token from LexisNexis Risk Solutions can provide benefits to the following markets:

Why Use Tokenization in Healthcare?

healthcare tokenizationA push towards collecting real-world data (RWD) and increasing focus on producing real-world evidence (RWE) to improve patient outcomes has created the need for an accurate longitudinal view of patients. This data needs accurate matching and linking over time and needs confidentiality in compliance with HIPAA standards.

It also needs to be able to ensure high confidence in combined data to link events and outcomes for the correct patient. This approach enables the tokenization engine to link together records that don’t “look” similar enough in other matching algorithms, while meeting HIPAA compliance standards. For example, our tokenization engine takes claims for Patient A, who has two different addresses and variations on her last name, and differentiates her from a sibling at the same address with a similar name, into a single record.

This tokenization process can help healthcare organizations link, secure and de-identify protected health information such as personally identifiable health information (PII/PHI), personal health records (PHR), electronic health records (EHR), and electronic medical records (EMR) while maintaining privacy and compliance and a high degree of precision.

Benefits and Use of a Patient-Centric Token in Healthcare

Depth and breadth of data enables
a more powerful token

LexisNexis Risk Solutions leverages over 10,000 sources of data tied to billions of records. Through our extensive data resources, six billion permutations of Personal Identifiable Information (PII) are observed across 280M adult identities due to changes and choices during a person's lifetime.

We are able to accurately match data over time as patient information changes, achieving high match rates with precision across multiple datasets. This precision and longitudinal accuracy coupled with extensive capture of data through a person’s life, allows us to create a more powerful token for the healthcare industry.

The patient-centric token is longitudinally comprehensive

The LexisNexis Patient Centric token enables high confidence in combined data to link events and outcomes for a patient, critical for today’s research-driven use cases in RWD/RWE, precision medicine and care outcomes. By combining the patient centric token with data assets that offer a complete picture of the patient – medical events and EHR records, along with SDOH – healthcare organizations and companies can leverage data and analytics to assess effectiveness and gaps between efficacy and real-world treatment impacts for a lower cost. The patient centric token can be linked to other data sets that tie back to a broader view of the patient, controlling for differences in the population but can also potentially identify similar characteristics and different levels of effectiveness. This helps companies develop products that yield improved outcomes in real world use, not just study efficacy.

Secure data exchange

Tokenization secures and desensitizes data by removing information from the daily business environment and replacing it with non-sensitive tokens. PII / PHI remains fully within your control and within your environment, enabling transactions with third parties without data or your tokens leaving premises. End-user specific tokens are generated for internal use for patient data management.

This enables secure transactions with third parties, without data or your tokens leaving premises, not simply complying with de-identification standards but ensuring risk mitigation at every step. Using our approach to tokenization, customers experience superior levels of data quality (accuracy, precision and completeness) while maintaining superior levels of security through data sharing, data warehousing, data exchange and analysis.

Solve for outcomes and efficacy challenges

With the LexisNexis Patient Centric Token, a de-identified record can be enhanced with other elements like social determinants of health, claims data and mortality data to offer a more robust solution to solve analytics challenges. The impact of these additional variables upon the token gives that true longitudinal view missing from other data offerings in the market.

In understanding that a full 50% or more of the impact on health is driven by social determinants of health, we have built data solutions to enhance understanding of a patients’ risk and the related care drivers that indicate potential barriers to care. In addition to SDOH data, medical claims data is key to RWD/RWE efforts and outcomes and efficacy research, enhancing and expanding upon the data available for inquiry. Finally, adding mortality events enable mortality studies and enhance real-world data. By adding these three complex data assets to the token, your organization will uncover a longitudinal and comprehensive record of a patient without compromising their identity.

A Patient Centric Token Aggregates Relevant RWD to Impact Patient Outcomes

healthcare tokenizationHealthcare organizations can securely move towards efficient, transparent, and patient-centric operations with a singular resolution of previously disjointed patient data. Our Patient Centric Token leverages the industry’s largest consumer referential database to create hashed links to all available information about a patient, overcoming variations in the patient’s PII to provide a longitudinally continuous and comprehensive view of a patient.

The Patient Centric Token performs better than row level tokenization, indicating up to 20% improvement in healthcare-relevant scenarios. It makes sharing, matching and linking of patient data, and obtaining real world data easy through a de-identified data market.

LexisNexis Risk Solutions uses a proprietary combination of datasets to create a singular, comprehensive, patient-centric healthcare data token. The result is a token resilient to changes in PII over time, linking patients together across variations in PII. This reduces cost and complexity of managing multiple tokens. This key differentiator of the patient centric token enables life sciences and other healthcare organizations to securely and accurately access patient-level data that would otherwise be unavailable.

Patient Centric Token and Social Determinants of Health Data

By accessing this de-identified single token with a longitudinal view, companies can test the efficacy of drugs and outcomes, validating research and development of new products. Companies can use our de-identified single token to validate the performance of an intervention under ‘real-world’ conditions. In addition, adding Social Determinants of Health creates a broader view of the patient and enables identification of and control for confounding variables. Linking to other data sets that tie back to a broader view of the patient, like social determinants or behavioral data, help to control for differences in the population but also potentially identify similar characteristics that are tied to different levels of effectiveness.
