MEDICAL HISTORY DATA SYSTEM AND METHOD THEREFOR FIELD OF THE INVENTION
The present invention is directed to a medical history data system and method whereby a portable data card is generated bearing a patient ' s medical history in a plurality of languages. The system provides a means whereby individuals can obtain a card from a vendor via an on-line connection and is of particular suitability to individuals who travel. The system and method are readily adaptable to veterinary uses as well. BACKGROUND OF THE INVENTION
The need for a portable, readily available medical history device which can be easily carried on the person is evident, particularly today where so much international travel takes place. In medical emergencies it can speak for the individual, potentially avoiding mistreatment and possibly death. With large HMO's and insurance companies, referred patients need not wait for paper records to be copied and delivered to specialists, laboratories and diagnostic centers, and errors in such retrieval and copying would be eliminated. If the portable medical history can be extended, a patient's complete medical record may be permanently in his or her possession, and by extension, medical records of the primary care giver and central insurance files may be updated electronically. Fraud can be more easily detected and eliminated and omissions and redundancy will become evident and will be reduced. In addition, adverse drug interactions may be avoided since the portable medical history may include data on all prescriptions being taken.
To create a portable medical record which can perform in the manner described above, certain conditions must be met: 1) the record must be small in physical size, able to be carried in a wallet or purse; (2) the record must be capable of being read using equipment commonly in use throughout the U.S. and the world; (3)
the record must be tamper proof, i.e., not erasable or changeable; (4) it must be possible to add new data to update and keep current the existing recorded data; (5) the record should have ample capacity to store EKG's, X- rays, MRI ' s CT Scans and other electronic scans and significant data.
Portable systems now in use include the following:
Magnetic Strips and disks: these have very limited capacity, generally not more than a few hundred bytes and are suitable for identification purposes but are capable of being erased or changed.
Smart Cards : these cards have an embedded microchip, widely used in Europe as identification and value/debit cards with a typical capacity of 8 to 16 kilobytes . Smart cards are capable of easy erasure and change and are not tamper proof. Furthermore, they require special readers which are not widely available. Flash Memory Cards : these contain memory chips with capacities up to several megabytes. However, some types require a power source in order to maintain their stored data and all can be damaged or erased by strong magnetic fields. In addition, as with the smart cards, special readers which may not be readily available are required.
There is, as yet, no easy, reliable and readily portable means whereby a person may carry with them their complete medical history, including, if desired, X-ray data, EKG, EEG, MRI and CT scan data in a form that is both non-bulky and readily available to medical workers regardless of the condition in which the patient may be in. Furthermore, there is no system by which an individual may easily obtain such a portable medical history which may fit in a wallet or passport jacket when travelling and be readily available when needed and which has their medical history stored thereon in a plurality of languages .
The present invention provides a system and method which employs commonly and widely available materials and equipment to produce a medical data card that is permanent, tamper proof, fits easily into a wallet or purse, contains data which may be readily extended or updated, is completely within the control of the person owning it and can be copied electronically into the records of medical and insurance companies to provide the detail and scope needed to minimize fraud, error and waste. Emergency personnel, upon being given or finding the card will be able to read it using standard equipment already in possession to note important data regarding allergies and prior medical conditions of the patient so as to guide them away from improper treatment. In addition, using available communications technology they will be able to transmit the data to the hospital while en-route thereby eliminating any delay which may be caused by having to wait for paper records or relative to be located. Furthermore, the medical data card produced by the system and method of the present invention is inexpensive and economically affordable to almost all persons in the civilized world.
The present invention makes use of the large capacity, stability and almost universal applicability of CD-ROM media coupled with on-line access via the internet to provide a patient data card on which individuals may record their personal information and medical history in a manner so as to be readable on any computer system having a CD-ROM drive. In addition, the present invention provides a system whereby individuals may obtain a card directly from a vendor without having to go through their health care provider, insurance company or HMO and where the medical history data stored on the card is available in a plurality of languages.

The present invention provides a medical history data system and method therefor whereby personal medical history is received directly or by entry at an Internet website, and is recorded or "burned" directly onto a customized compact disk, or CD. (The term, "burning", reflects the action of a laser used to record digitized data and sound onto a CD-ROM disk.) While the CD may be used in its full size of approximately 120mm (4.72") in diameter, as available worldwide, advantages are enjoyed when it is trimmed by mechanical means, first to a smaller diameter of about 60mm to 80mm, preferably 79mm (3.11"), i.e., the so-called mini-CD, so as to fit into the shallow depression in the center of the tray in standard CD-ROM players, then to trim two parallel sides between about 44mm (1.73") and 60mm (2.36") apart, equidistant from the center of the CD. The preferred trimmed width is 54mm (2.13"), which is approximately the width of a standard credit card. Personal medical history data is received from an individual in many ways . It may be transmitted in writing, by telephone to an entry technician, electronically either by direct download or by completing an electronic form or worksheet on the vendor's web site. The information provided is converted into a file that is readable by a personal computer and is recorded or burned onto the CD. After recording, the CD, trimmed or
untrimmed, is identified by a serial number and a label with the individual's name and address, as obtained from the data provided following playing of the completed CD to ensure that the data has been properly burned onto the CD. The completed CD, which is termed the "PDCard", is printed with basic instructions and placed in a protective sleeve with a visible tab at the open end to enhance recognition and identification. The individual carries the sleeved PDCard in a wallet, purse, passport folder or other location for easy access in case of emergency requiring medical help.
In the event of such an emergency, the individual, now the patient, presents the PDCard to the emergency response paramedic or the emergency room nurse, or other medical worker, who will read the instructions and place the PDCard in a standard CD-ROM player in their available computer and play it as one would play any CD. The patient ' s medical record is displayed on the computer monitor preferably as a text file so as not to be dependent on any one particular operating system or word processing software. The medical record includes the pa ient's personal information, i.e., name and address, followed by the names, addresses and telephone numbers of persons to notify in the event of an emergency, the patient's doctors and insurance data, any allergies and medical conditions that medical workers would need to be aware of and then the patient's brief medical history. In addition, the PDCard may include laboratory data, EKG's, scans, electronic records and any other information deemed important to identify special medical conditions pertinent to the individual. Having such information at hand, the response team, emergency room team, or other medical workers will be warned of potentially improper medication or treatment thereby avoiding further injury or death to the patient.
A CD, trimmed as preferred, has approximately 20 to 40 megabytes of storage memory which is believed to
be much more than adequate to store complete medical histories and records for most people, including blood analyses, scans of X-rays and EKG's and direct electronic records of CT, MRI, ultra-sound and other scans. For this reason, the invention also includes the method by which the PDCard, as above described, may be used as a patient identification card for clients of health management organizations, physician associations and health care insurance companies. The patient's PDCard may be updated by burning in the date, physician's name and nature of visit with a report, once written and available, to be added on the patient's next visit or transcribed from a physical or electronic report sent to the patient's primary care physician or the insurance company or HMO. If data needs exceed the maximum capacity of the PDCard, the data may be compressed before burning onto the card. The complete electronic file may be maintained on a full size CD for the patient at the HMO or insurance company headquarters or in a central database suitably backed up for security.
The language used in preparing and recording the medical data may be any language which has been reduced to an electronic form suitable for use on personal computers . At present data input can be performed in English, French, Italian, Spanish or Japanese and output can be in any or all of these languages . Any language which has been made capable of writing to and retrieving from a personal computer can be applied. A separate keyboard may be needed for certain languages but such would already be in place for retrieval of data from the PDCard in a country using that language . For individuals who travel through a number of foreign lands, the PDCard may be prepared with the medical data written in all languages to be encountered. In this case, the entered data is translated into the desired languages and burned onto the card as a single file to be displayed when played. The medical worker
simply scrolls through the data displayed until the local language appears. Preferably, however, separate files for each language are prepared and burned onto the card. Upon playing the card, the medical worker is presented with an initial screen having an index means permitting him to easily choose the correct language file for that country. In view of the wide use of internet browser software and other programs which can read and display HTML files, it is also a part of the present invention to provide parallel files of the medical history data in HTML format which is capable of including graphic elements .
Figures 1 and 3 illustrate a preferred embodiment of the system for use by individuals to obtain a personal patient data card. In this embodiment, the individual customer preferably accesses the vendor's server via the vendor's internet web site. The vendor's home page includes a link to an electronic form stored on the server. The form corresponds to a data base on the server which is preformatted with predefined fields for the customer's personal information, such as name and address, etc., as well as a series of predefined fields corresponding to specific diseases, maladies, symptoms, conditions, allergies and the like. When the form is accessed, the customer is prompted to enter his personal data and to check or select all those predefined fields that are applicable.
In addition, the data base includes, and the form provides, arbitrary fields for entry of comments and information concerning any allergies the customer suffers from, any medications that have been prescribed and that the customer is taking, any surgery the customer has undergone and any periods during which the customer was hospitalized and the reasons and treatments associated therewith. The arbitrary fields permit the customer to include details that cannot be conveyed merely by a yes of nor response.
Also located on the server is a translation program which is keyed or linked to the data base and which is capable of providing a translation of the personal and medical information entered by the customer into one or more languages other than that in which the data is entered. Upon completion of the data entry, a data file consisting of the personal and medical information entered is created and the customer is presented with a selection whereby he can request or decline translation. If translation is declined, the customer is directed to a screen for handling payment information. Payment for the service provided under the system is handled by a secure credit or debit card transaction through any one of several means which are known in the field of on-line financial and sales transactions and. which do not form a part of this invention other than to facilitate the commercial application thereof.
Where the customer requests a translation, the translation program is activated and the customer is prompted to select the languages into which he desires the data to be translated. For example, if the customer is planning a trip to Europe, then he might select French, German, Spanish or Italian. Alternatively, someone who travels to Japan might select Japanese. The number and selection of languages which may be available is limited only by the capability of the translation program and it is within the scope of this invention to permit the selection of a plurality of languages. Once the languages are selected, the translation program operates to generate the translations and to create separate data files for each language selected. The customer is then directed to the payment screen as described previously. Following completion of the financial transaction, the customer may be informed of the expected time of delivery for his data card and then may be
prompted to log off or go to another location. In the meanwhile, the server continues to process the data files by directing them to a data transfer means for transfer to the data card. As previously described, the data card media is preferably a CD-ROM, most preferably a specially trimmed mini-CD-ROM such as that shown in Fig. 2. Such specially trimmed mini-CD's can be obtained from Shape CD, Inc. of New York, pursuant to their U.S. Design Patent No. 419,152. In order to prevent inadvertent damage to data stored thereon, it is preferred that the data card or CD be recordable only rather than a rewritable CD format. The data transfer means is a CD recorder or "burner" , and transfer of the data files from the server to the recorder causes them to be written to the data card. In addition, copies of the data files are sent to a backup storage and are kept for a limited period of time by the vendor in the event an error in the data is detected during testing or is reported by the customer. The recorded data card is checked for accuracy and, using the personal information entered by the customer, a label bearing the customer's name is applied to the data card before it is mailed to the customer. In order to accommodate as many different computer systems as possible, the data files generated and stored on the data card are preferably in a common TXT format which can be read by any word processor. In addition, given the widespread usage of the Microsoft Windows operating system and web browsers, the data files may also be provided in HTML format. Other formats in which the data may be stored include Adobe ' s Portable Document Format (PDF) and Rich Text Format (RTF) .
As an alternative to direct access to the vendor's site and the system over the internet, it is within the scope of this invention to permit a customer to access the vendor by telephone and speak to a technician. In this embodiment, the technician has
direct access to the server and takes the customer's verbal information and transcribes it into the system. In this embodiment, the technician merely serves as the intermediary between the medical history data system and the customer .
Fig. 4 illustrates the steps in the use of the data card by a health care worker. When the customer is in need of medical attention, the card is given to a doctor or emergency medical technician or other health care worker who places it into a standard CD drive in their computer. The card includes a program which is self executing and displays an opening screen which identifies the card as bearing the customer's medical history and, where the data is present in different language files, displays a menu which permits the health care worker to select the desired language. Upon selection, the appropriate TXT, HTML, PDF, RTF or other format file is displayed thereby providing the health care worker with the customer's medical history. CD-ROM's, including mini-CD's and the trimmed
CD format which is preferred in this invention, have a capacity of from tens to thousands of megabytes . Accordingly it is possible to store image files in addition to the, medical history information described herein. In a further embodiment, the medical history data system includes means to receive scanned data and appropriate software to create image files of such scanned data for storage on the data card. Means to receive scanned data may include an optical scanner whereby image data from hard copy is scanned into the system or an on-line link accessible by doctors and hospitals whereby X-ray, MRI, CT scan, EKG and EEG data can be directly downloaded to the system and added to the data stored on the data card. As is the case with the medical history data, image data can be stored in several formats, for example, Bit Mapped Graphics (BMG) , JPEG, or any other commonly used graphic or image format.
The system and method of the present invention are readily adaptable to use by insurance companies, HMO's and the like, for use in providing the service to their subscribers. In such instances, the insurance carrier may have direct access to the vendor with parallel access from the insurance history storage facility. The operation of the system is substantially the same with the exception that a separate financial transaction step will not generally be required since the insurance company will generally have a contract with the vendor. In addition, instead of mailing the completed data cards to the insured, the vendor will send the cards to the insurance company or HMO for distribution to their subscribers . The system also lends itself to easy updating of the data cards either by simply issuing a new card with updated information, the cost of CD-ROM's being relatively low, or by having the customers or subscribers return their own cards for updating with data downloaded from doctors, insurance companies or HMO's.
Alternatively, through arrangements with participating doctors, hospitals, HMO's, and the like, the vendor can, provide those entities with the software and CD recorder drives necessary to permit direct updating of customers ' and subscribers' cards with a report after each visit to their health care provider.
The present invention has applicability as well in the veterinary fields to maintain records for prize animals and for animals raised specifically for breeding where records of provenance such as awards, training and pedigree and medical records such as inoculations, medications and treatments are needed. As described herein, the data is burned onto a trimmed CD, placed in a waterproof plastic case and hung on a collar around the animal's neck or kept in a safe place together with positive means of identification, such as a breeder's book or the like. Specific types of animals which may
benefit by such records include, but are not limited to, thoroughbred dogs, cats, horses and livestock, especially prize stock raised for breeding.
The foregoing description presents the preferred embodiments of the present invention and it is understood that many variations and modifications of those embodiments will be evident to those skilled in the art and may be carried out without departing from the spirit and scope of the present invention.
