5.1 This standard describes a proposal to provide unambiguous personal identification for any patient who requests it. In today’s world of specialized healthcare and mobile patients it is typical for clinical information on a single patient to reside in a variety of locations, some using manual data storage techniques, but an increasing number using electronic means. In order for a clinician to provide safe and appropriate clinical care in this environment it is necessary to be able to aggregate appropriate clinical information on a specific patient in order to gain an accurate and comprehensive picture of that patient’s clinical situation. This implies that all information relating to each patient should be identified in a unique manner to facilitate the process of accurately aggregating appropriate information.

5.2 The converse of the need for data aggregation is the patient’s need to protect the privacy of their information. Unless patients are confident that they can avoid inappropriate sharing of clinical information they will not readily share that information with caregivers. Thus, the same system that supports unambiguous linkage of all information concerning a patient must also play a role in protecting the privacy of that information.

5.3 The proposed patient identification system must be able to avoid or overcome the numerous objections that have prevented implementation of a universal patient identification system in the past including issues related to:

5.4 Experience has shown that a healthcare identification system will only be feasible if it is dedicated exclusively to the needs of healthcare. It is only in this focused environment that it has been possible to create a consistent, feasible, functional, and effective design for such a system.
