title: Design and implementation of computer-readable patient data cards--applications in Europe.
abstract: Computers have been widely accepted today as essential tools for handling and processing an ever-increasing flood of information. At the same time people, including patients and medical staff, are becoming more mobile and face the problem of interacting with the different computerized systems. We are also experiencing the acceptance of the small rectangular plastic cards as the instrument for vast numbers of transactions throughout the world. These factors have highlighted the possible attractions of machine-readable patient data cards that can be carried by the patients themselves. The patient data card is expected to provide quick reference information to any physician or health worker consulted by the carrier. This information should avoid duplication of diagnostic, therapeutic and prescription measures and help give a conveniently structured summary of the patient's medical history. Advances in technology have made it possible to move from the familiar credit card which can store only a limited amount of information, to new, similarly shaped cards with much greater capabilities. The basic technologies for patient data cards are examined. An analysis is then attempted of the possible information contents of such a card that could be used at a national and European level, and of the field trials in Europe so far. Questions of security and standardization are also addressed. A number of conclusions and recommendations are also made which are based on the experience gained from a relevant implementation attempted, and participation in a recent study undertaken by the EEC in the area.
