PATIENT IDENTIFIERS
UNIQUE PATIENT IDENTIFIERS
Strategy for Assigning UPIs
A UPI requires a sequence allocation sufciently large to cover an entire population over time, theoretically for as long as the number will be in use. Sequencing schemes available for development of a UPI generally fall into three numbering systems: serial, derived, and composite.
•In serial numbering systems, each individual is assigned a number from a central location. These numbers are automated and do not assimilate any nonunique characteristics of the individual. England’s National Health Service number is an example of serial numbering system, with some added functionality.
•As the name suggests, derived numbering systems create a number based on, or derived from, a personal trait of the individual. In contrast to serial numbering, assignment of a derived number can take place anywhere but runs the risk of failing to be unique when derived from a personal trait which is shared by other individuals.

Attributes of Ideal Identifers (cont)
Meeting all of the proposed criteria would lead to a UPI that achieves
the following:
•
positively identifes patients.
•
automatically links and collates patient records from disparate
electronic sources, creating a longitudinal care record,
•
protects patient’s personal health information and privacy,
•
efectively minimizes the cost of patient record management.

•
A unique identifer, by defnition, can never be associated with more
than one individual. That is, once assigned, the possibility of another
person being assigned the same number must be eliminated, or
infnitely minuscule.
•
A ubiquitous identifer is available and accepted across the health
care spectrum. For example, a nonubiquitous identifer would identify
a patient for a hospitalization but not the subsequent primary care
visit. Ubiquity also requires the identifer to be durable and made
readily available at the time of service.

Attributes of Ideal Identifers (cont)
•
Uncontroversial. The identifer should help minimize the opportunities
for crime and abuse and should not contain substantive information
about the individual. Similarly, the various stakeholders must perceive
the identifer to be minimally invasive. The subjectivity of what is and is
not invasive makes universal acceptance difcult, if not impossible.
•
Uncomplicated. An identifer or identifer system that is not practical to
implement or that does not meet the requirements of administrative
simplifcation must be deemed unacceptable.
