Current Healthcare Environment
Heterogeneous clinical automation environmentNo standards for patient identificationFederal govt. continues to avoid healthcare identifierIncreasing automation & information exchange8-10% EMPI matching error ratesHealthcare identity theft grew 112% in 2009Lost information, duplicate recordsInadequate privacy managementUnique patient identifiers can address all of these needs
2
Goals of a Potential Solution
Eliminate patient identification errors
Improve privacy management
Reduce medical identity theft
Cost effective
Deployable across a variety of policies
Simple, uniform syntax with consistent semantics
Standards-based
Implementable across a variety of technologies and geographies
Eliminate potential for counterfeiting

VUHID Mission Statement
The goal of the Voluntary Universal Healthcare Identification (VUHID) project is to make unique healthcare identifiers available to individual patients who want one to enable:– unambiguous patient identification – error-free linkage of clinical information – enhance the privacy of patient information – improve the quality of medical care – reduce the rate of medical errors – decrease the incidence of healthcare-related identity theft – help control healthcare costs
4
Identification Errors are a Patient Safety Issue
False positives create a clear patient danger
False negatives mean duplicate records, additional cost and needed information may not be available
Additional (duplicate) testing is expensive and can be dangerous
Good clinical decision support requires accurate and comprehensive information
Time spent looking for information is time not spent diagnosing and treating the patient

One Possible VUHID Card Configuration
HIE designs card format and produces the cards
Issued when the patient obtains their VUHID identifier
Stays permanently with the patient
Identifier is printed on the card
Has at least one machine-readable representation
–Bar code–Magnetic stripe–Smart card–RFID? (privacy concerns)
Photo/biometric may be included

Two Categories of IdentifiersVUHID identifiers are either an OVID or PVIDOpen Voluntary Identifier – OVID– Shared patient information for administrative, financial and
clinical uses– Patient identity is known– Wide variety of “open” medical uses
Private Voluntary Identifier – PVID– Many different classes:
• Psychiatry, STDs, research, genetics, etc.– Patient identity is not necessarily known
• Patient, selected physician(s), EMPI system– Specific set of “rules” for each privacy class
Ideally, a person has one OVID and many PVIDs Multiple OVIDs for one person are not ideal but tolerated

VUHID Benefits
Consistent syntax and semantics for patient ID
Globally unique identifiers – no identification errors
Ability to embed privacy constraints
Lifetime identification for a patient
Ability to terminate if fraud/error detected
Reduce identity theft
Concurrent support for multiple policies & technologies
Counterfeit resistance
Language independence/internationalization
13
HIE Value from VUHID Identifiers
Internal– Reduce duplicate records, save time, eliminate lost data,
improve medical outcomes, eliminate cost and waste, better achieve meaningful use, reduce duplicate tests
External– Improve accuracy and efficiency of information exchange,
enable longitudinal medical records, enable data sharing for research and reporting
Both– Reduce medical identity theft, improve privacy management,
support multiple languages, eliminate counterfeiting
