Abstract

A system and method for data compression of structured medical history information using multiple, updatable, static dictionaries in conjunction with an advanced probability-based model. The system is not a free text, word or phrase compressor as is presented in generalized or universal data compression systems. It employs a series of static dictionaries consisting of structured data developed from standardized medical classifications of disease, disorders, surgical procedures and medications. Prior probability information is utilized to achieve a high level of data compression of multiple data items at a time. The dictionaries are designed for flexible updating, efficient storage and retrieval, and data integrity. A portable medical card may be imprinted with the compressed medical information.

Claims

1. An apparatus for storing medical information comprising:

a tangible medium comprising;

a first displayed portion comprising computer compressed medical information in;

a field of a sequence of order-specific human readable characters chosen from a set of characters,

wherein the sequence of characters is chosen, determined and displayed in the first portion in a unique order dependent on a specific sequential ordering of computer-generated data encoded to represent a patient'"'"'s medical information, and

wherein the computer compressed medical information is compressed based on multiple updateable static dictionaries and a statistical model of prior probability information to take into account that the incidence of disease, disorders, surgical procedures and medications is related to the patient'"'"'s demographic grouping, and that certain diseases, disorders surgical procedures and medications will most likely occur in combinations;

and

a second displayed portion comprising uncompressed human readable information in;

an identifying field of versions of a computer program, the multiple updateable static dictionaries, and the statistical model used to compress and produce the computer compressed medical information displayed in the first portion,

a date field of the effective date of the computer compressed medical information,

an initials field of initials of the patient,

an emergency information field of emergency information for emergency treatment of the patient, and

an information field comprising telephone and world wide web information for remote decoding of the computer compressed medical information.

2. The subject matter of claim 1 wherein the computer compressed medical information is compressed based on statistical interrelationships between different categories of medical data for a patient population.

4. The subject matter of claim 1 wherein the computer compressed medical information is compressed by assigning shorter codes to data items occurring frequently in a patient population and by assigning longer codes to data items occurring less frequently in the patient population.

5. The subject matter of claim 4 wherein the computer compressed medical information is compressed by assigning the data items to one or more groups, and by encoding each data item based on the occurrence frequency of that data item in the assigned group.

6. The subject matter of claim 1 wherein said human readable characters are selected from a group of alphanumeric characters selected to reduce misreading of said alphanumeric characters.

7. The subject matter of claim 1, wherein the tangible medium comprises a portable medium surface containing the first and second portions, and wherein the human readable characters can be displayed in the first portion on the portable medium surface as separate lines composed of a fixed number of groups of a fixed number of characters.

8. The subject matter of claim 7 wherein each group of characters incorporates error-checking information.

9. The subject matter of claim 1 wherein said human readable characters are arranged in a prioritized sequence.

10. The subject matter of claim 1 further comprising a translator for receiving and decompressing the sequence of human readable characters and displaying the patient'"'"'s medical information in human readable form.

11. The subject matter of claim 10 wherein said sequence of human readable characters is received by said translator as a human voice over a telephone line.

12. The subject matter of claim 10 wherein said sequence of human readable characters is received by said translator digitally over a telephone line.

13. The subject matter of claim 1, wherein the multiple updateable static dictionaries comprise structured classifications of medical data codes.

14. The subject matter of claim 1, wherein the tangible medium comprises a card.

15. The subject matter of claim 1, wherein the tangible medium comprises a computer screen.

16. The subject matter of claim 1, wherein the sequence is stored on a computer-readable medium.

17. The subject matter of claim 1, wherein the statistical model of prior probability information comprises combinations of medical data items organized by demographic groupings, such as the patient'"'"'s demographic grouping, which can include the patient'"'"'s age, sex and race, and wherein the combinations of medical data items are ordered using a weighting factor of a frequency of each combination multiplied by the number of tuples in each combination.

18. The subject matter of claim 1, wherein the computer compressed medical information in the first portion is determined from the patient'"'"'s medical information encoded initially to achieve a zeroth order data compression using the multiple updateable static dictionaries by an assignment of fixed length pointers to each static dictionary data item.

19. The subject matter of claim 1, wherein the computer compressed medical information in the first portion is encoded to achieve a fourth order data compression using a statistical model of prior probability information used to assign short variable length pointers to combinations of medical data items taken one at a time, two at a time, three at a time, and four at a time.

20. The subject matter of claim 1, wherein the computer compressed medical information reduces the patient'"'"'s medical history to less than 125 alphanumeric characters in the first portion.

21. The subject matter of claim 20, wherein the computer compressed medical information can be created or updated for storing the patient'"'"'s medical information without special electronic, magnetic, computer memory chip, or laser media, and without any special manufacturing equipment or special manufacturing processes.

22. The subject matter of claim 20, wherein the sequence in the first portion is translatable into the patient'"'"'s actual personal medical history without using a central database of patient records or online patient records.

23. The subject matter of claim 1, wherein the sequence in the first portion is encoded for privacy and security using data encryption and password protection.

24. The subject matter of claim 1, wherein the sequence in the first portion is displayed for quick and reliable entry into a computer without an electronic reader, scanner, or other special reading equipment.

25. The subject matter of claim 1, wherein the sequence in the first portion can be transmitted as corresponding signals across the Internet while maintaining privacy and security of the medical information.

26. The subject matter of claim 1, wherein the sequence in the first portion can be translated and updated by software accessed remotely by a computer connection to the Internet.

3. The subject matter of claim 3, wherein the different categories include the diseases, disorders, surgical procedures, and medications.
