SYSTEM AND RELATED CHIP CARD TYPE PORTABLE STORAGE MEDIUM FOR MANAGING HEALTH DATA
5 The present invention concerns a system, and the portable storage medium, preferably a chip card type electronic and/or magnetic card, used by the system, for managing health data, also comprising administrative data of interest for providing health services, that allows a timely reference and a rapid updating of all health data related to each 10 individual of a however large population, ensuring a very high safety and privacy, so as to enable any authorised health operator to know in a controlled manner, for instance, the anamnesis of the patient for assessing in good time possible diagnoses, with a consequent decrease of complications and mortality rate due to delayed diagnoses, the system 15 being simple and inexpensive to make, install, and use.
The present invention further concerns an electronic device for reading said portable storage medium.
It is known that in the field of health services management, at local level, as in a single hospital site, but still more at geographically
20 distributed level, as in a region or over the whole home territory, detailed management of health data of the population benefiting from the same services is of fundamental importance.
In fact, a detailed knowledge of health data, as much updated as possible, which form the patient anamnesis, would allow to assess in
25 good time diagnoses of possible pathologies, to arrange proper prevention campaigns for persons at risk of specific diseases, and to carry out either exact or statistical searches on specific samples of population.
However, the large amount of information to manage has rendered the implementation of an efficient and reliable health data 30 managing system complex and expensive so far.
In fact, the systems developed so far suffer from some drawbacks which have highly limited their applications.
In particular, the existing systems are limited to the management of a very reduced portion of data of extremely limited 35 populations, such as those receiving a specific health service within a health site. For instance, there exist systems allowing the management only of administrative data within a whole hospital site, but which do not manage health data of the services received in one of the divisions of the
same structure; these data are managed by a further different managing system, such as those making use of the HL7 protocol for managing an electronic case history made up within a specific division of the hospital site. This entails a great difficulty in integrating data managed by different systems, which are often not even capable to automatically communicate with each other, with a consequent delay of the availability of the same data, an unavoidable incompleteness of available health data, and an increase of the maintenance costs for these systems, due to the large number of personnel that is to be involved in data entry and updating. It is therefore an object of the present invention to provide a system for managing health data of a however large population, that allows a timely reference and a rapid updating of all health data, also comprising administrative data of interest for providing health services, related to each individual of a however large population. It is still an object of the present invention to provide such a system that ensures a very high data safety and privacy.
It is further an object of the present invention to provide such a system that is simple and inexpensive to make, install, and use.

It is still subject matter of the present invention a portable storage medium, characterised in that it stores identification data of an individual capable to be read by at least one processing apparatus for enabling this one to refer to and/or update at least one portion of health and/or administrative data stored in one or more databases, and in that it is capable to be used by the previously described system for managing health data of a plurality of individuals of a population.
It is further subject matter of the present invention an electronic reading device, capable to be connected to at least one processing apparatus, characterised in that it is capable to read at least one portable storage medium as just described, and in that it is capable to be used by the previously described system for managing health data of a plurality of individuals of a population.
The present invention will now be described, by way of illustration and not by way of limitation, according to its preferred embodiments, by particularly referring to the sole Figure of the enclosed drawings, in which it is schematically shown a block diagram representing a preferred embodiment of the system according to the invention.
The system according to the invention comprises, for each health site, at least one processing apparatus 1 , preferably a computer or a hand-held device (such a PDA - Personal Digital Assistant), or even a suitably configured mobile telephone, by means of which a health operator accesses, through a communication network 2, the health data of a user
stored in a database 3. The access is authorised through at least one portable storage medium 4, read by the processing apparatus 1 , that stores an identification code of the user whose data must be referred to and/or updated by the health operator. Preferably, also the health operators are provided with their own identification code, so as to allow a discrimination of the data which different operators may see and/or update and a distinction among the operations which different health operators may make on the same data (only reference, only updating, or both).
In particular, in the Figure a number of processing apparatuses are shown comprising, by way of example and not by way of limitation: a processing apparatus 1A located in a surgery; a processing apparatus 1 B located in a hospital; a processing apparatus 1C located in a first aid station; a processing apparatus 1 D located in a specialist's surgery; a processing apparatus 1 E located on an ambulance, which communicates with the network 2 by means of a wireless connection, for instance with cellular telephony, achieved through a receiving-transmitting antenna 5 connected to the processing apparatus 1 E communicating with a station 6 connected to the network 2; a processing apparatus 1 F located in a pharmacy; a processing apparatus 1G located in an orthopaedic workshop; a processing apparatus 1 H located in a medical device provider. It is evident that, as said, thanks to the identification code of the health operators, these will be capable to refer to and/or update only information (either as a whole or a subset thereof) which is pertinent to their own job. For instance, in case of an hospital administrative operator, he will be capable, through the processing apparatus 1 B, to read some administrative data (as user's personal data, reservations and already made visits, paid expenses) and to update other ones (as new reservations and visits to make); in case of a doctor on an ambulance, he will be capable to refer to medical data forming user's anamnesis; in case of a pharmacist, he will be capable to refer to some medical data, as sensitivities or intolerance to specific substances, possible previous therapeutic prescriptions, and still to give drugs and medicines previously prescribed by a doctor (recorded in the database 3, and possibly also in
the portable medium 4) and further to record (in the database 3 and possibly also in the portable medium 4) the given drugs and medicines, thus implementing a sort of electronic prescription system. In the latter case, by way of example, the doctor could record (in the database 3 and possibly also in the portable medium 4) a prescription, the user could go to the pharmacy and give the portable medium 4 to the pharmacist, who read, through the processing apparatus 1 F, such prescription highlighting the drug cost and the possible contribution (for instance a "ticket") that the user must pay; moreover, the pharmacist may further record (in the database 3 and possibly also in the portable medium 4) the occurred consignment of the drugs to the user. Such a system could be further adopted for having specialists' visits or for making lab analysis in hospital sites, whereby the recorded (in the database 3 and possibly also in the portable medium 4) electronic prescription would be read and interpreted by a processing apparatus of the hospital site.
The identification code of the health operators may be inserted through a conventional user-id/password type interface, or it may be pre- installed in the related processing apparatus (possibly confirming the operator identity with a standard procedure of request of a password, possibly accompanied by an operator's "user-id"), or it may be stored in a portable storage medium, as a key according to the USB standard or a smart card, similar to the user's medium 4.
Even the user may connect, by means of his/her own processing apparatus U1 through the network 2 to the database 3, after authorisation through the portable storage medium 4, read by the processing apparatus U1 and preferably after a further user's identification code allowing him/her only to refer to his/her own data stored in the database 3, and not to update (unless particular information, as for instance the expression of will to be an organ donor). The communication network 2 may comprise any combination of one or more standard communication networks (for instance even the Internet and/or a dedicated network), implemented through telephone, in particular cellular, connection and/or satellite connection and/or fibre optics connection. The portable storage medium 4 substantially constitutes the input port towards the database 3 containing the whole anamnesis history of all the individuals of the population since birth and along the whole
space of life. A subset of the health and/or administrative data of the user could be also locally stored on the medium 4.
Preferably, the portable storage medium 4 is a smart card provided with a microprocessor. The inventor has tested an embodiment of the system that makes use of the AT90S2343 chip card from Atmel Corporation. Such medium 4 comprises an electrically erasable programmable read only memory or EEPROM storing, besides the identification code of the user whose information is to be searched in the database 3, also a software application and possible further data allowing to set up the health operator's processing apparatus 1.
In particular, the connection between the medium 4 and the processing apparatus 1 may also occur through an external reading device connected to the processing apparatus 1 , so as to allow the use of already existing processing apparatuses 1. The database 3 could be also a database subdivided into a plurality of geographically distributed units. Preferably, the data structure is relational, still more preferably a RDBMS ORACLE 9i, comprising the following tables:
- a table related to the users' personal data, the information, even the historical one, of which may be rapidly referred to by the health operators;
- a table related to the health operators' personal data (for instance, regional code, worker status, specialisation, and number of patients of a doctor); and - a table related to the clinical data of all the reports concerning the users.
The system according to the invention may also embody non
ORACLE databases, made accessible through a suitably developed XML interface. In particular, updating of the users' clinical data coming from electronic case histories may be carried out through a connection according to the HL7 protocol with an external system.
Data safety and privacy are ensured by methods for encrypting the same during transmissions among the several components of the system. Moreover, personal data are preferably separated from health and clinical data, distributing them on several units. As said, data access level is modulated by recognition of the access entitlement owned by each
operator, through the related identification code.
The system is extremely versatile, allowing, for instance, a doctor or a pharmacist to make also reservations for visits or services and to simultaneously update in real time any operation executed through the medium 4 on the data of the relevant user.
Furthermore, along with the communication among the processing apparatuses 1 and the database 3, the system may also provide that, through the network 2, the processing apparatuses 1 of different health structures may communicate with each other, updating local databases of the same structures (as for instance the reservation ones).
The system is further applicable for the health recognition of users within another country who are citizens of a certain nation. For instance, the portable medium 4 could allow any European citizen, being in another country of the European Union, to receive the medical assistance of the latter, without any more preliminary wearisome bureaucratic paper to be deal with, as it is presently necessary. The same could obviously occur also in a wider territorial extent, allowing, for instance, the health recognition of European citizens in extra-European countries.
The advantages offered by the system according to the invention, that is moreover applicable to the management of health data not only of a human population, but also of an animal population, are extremely significant. First of all, it allows a high saving of national health system costs, improving organisational and communication abilities of the various health structures.
Moreover, the system according to the invention allows an enhancement in professionalism of the various health operators, most of all of the doctors, increasing their productivity thanks to the immediate availability of patients' health data.
Still, the system is extremely simple to use, versatile, and safe.
Furthermore, referral and updating of the health data substantially in real time allows the definition of practically immediate diagnoses, promoting a decrease of complications and mortality rate due to delayed diagnoses, and a timely control, if necessary, of all the movements of a patient within the territory served by the system, that may
be extended up to comprise whole national territories.
Finally, easy availability of health data allows to conduct either exact or statistical searches on specific samples of population.
The preferred embodiments have been above described and some modifications of this invention have been suggested, but it should be understood that those skilled in the art can make other variations and changes, without so departing from the related scope of protection, as defined by the following claims.
