Newsgroups: dec.mail.lists.rem-conf You are invited to the next MICE International Seminar which will take place next week. Please limit traffic for two hours from 14:00 GMT on Tuesday, February 22. This seminar will be transmitted on the usual multicast addresses (please see the sd entry), and will be advertised in sd from Tuesday morning. Further information of this and future seminars is kept in the URL http://www.cs.ucl.ac.uk/mice/seminars.html Bruno Struif (GMD) speaking from Darmstadt, Germany will give a presentation on: "The Privacy Enhanced Electronic Prescription". Abstract -------- In Germany, more than 500 millions prescriptions are issued per year. Normally, the patient receives the prescription in the doctor's practice and takes it to a pharmacy where he gets his medicaments. From the pharmacy, the prescription is physically transported to a pharmacy computer center where it will be processed in different ways. Finally the patient health insurance gets this prescription with listings containing the result of the processing in the pharmacy computer center. Since the prescription is a paper document, the processing is difficult, time-consuming and cost-intensive. The introduction of the health insurance card in Germany will improve the technological environment in the doctor's practices.The prescriptions will be produced in the future by using the health insurance card, a personal computer and a printer. The model presented shows that the electronic presentation of the prescription produced in the doctor's PC can be maintained so that the difficult and expensive way of processing paper prescriptions in the pharmacy, the pharmacy's computer center and finally by the health insurance can be avoided. The solution described and already implemented at GMD is - to sign the electronic prescription by the doctor with its physician smartcard capable to compute digital signatures - to write the electronic prescription in the patient's smartcard - to prove the authorization of a pharmacist for the access to the patient's smartcard by using a pharmacist smartcard - to electronically transmit the electronic prescription together with pharmacy information (name of the pharmacy, prescription cost etc) to the pharmacy computer center or the health insurance computing center where it can be automatically processed. The patient gets therefore two representation forms of the prescription, the electronic form and the paper form. The paper form is still necessary in the relationship doctor/patient/pharmacist, since - the patient has a right to look on the issued prescription, - in case of malfunction of the patient's smartcard in the pharmacy the delivery of the medicaments has still to be possible and - the assembly of the medicaments is easier with a paper form in the hand. In the new release of the electronic prescription model a step in the direction of data privacy has been made. The personal data of the patient and the doctor are replaced by digital pseudonyms in a way that the pharmacy computing center and the health insurance can verify only certain characteristics, e.g. that the prescription has been issued by a registered doctor and that the related patient is a member of the respective health insurance. In special cases, a re-identification of the doctor or the patient is possible by using re-identification smartcards.
