Abstract

The storage and retrieval of healthcare information is provided by use of a database that facilitates a number of different tasks that require manipulation of patient data. Comprehensive patient data representing a group of patients may be retrieved based on patient descriptive categories including diagnosis, e.g. anatomy, pathology or clinical presentation as well as treatment and outcome factors of each case. Symbolic codes assist in storage and retrieval of some of the data. In storage, various of the patient data related to particular patient issues and events may be linked for easy retrieval of relevant data. The catagories include data options that may be organized in the form of a hierarchical tree that has branching levels of data options with increasing specificity. Data from the various levels may be compared, as well as data between individual categories. In some embodiments, selected multimedia data may also be accessed based on criteria from data options of the patient descriptive categories.

6. The method of claim 1, further comprising retrieving multimedia data related to the patient data results by the identifier.

7. The method of claim 1, further comprising creating a report for at least two of audit, mortality and morbidity, reporting, discharge list, and accreditation case log.

8. The method of claim 1, wherein the patient data results are related to at least two tasks of a group of tasks consisting of patient management, clinical outcomes tracking, healthcare research, training of healthcare professionals, fulfilling certification or accreditation requirements, clinical trials, quality improvement assessment, informed consent tracking, risk mitigation assessment, access to multimedia files linked to treatment events, data collection for export to other database systems, and billing.

9. The method of claim 8, wherein the patient data results is related to at least three of the tasks.

10. The method of claim 8, further including transferring the patient data results to a form for patient management, clinical outcomes tracking, fulfilling certification or accreditation requirements, clinical trials, quality improvement assessment, informed consent tracking, risk mitigation assessment, and billing.

11. The method of claim 1, wherein the patient data results include at least one level of a category hierarchical tree having data options arranged in increasing levels of specificity.

12. The method of claim 11, wherein the patient data results include patient data common to the received criterion and criterion from lower levels of the hierarchical tree.

13. A method implemented in a computer system for organizing healthcare patient data in a database, comprising:

receiving selected patient data from data options in at least one category including diagnosis, treatment and outcome;

storing in the database, the patient data with a unique patient identifier to relate the patient data within a data set, each data set being for a different patient; and

storing a linking event identifier for linking event data to link at least some of the patient data related to a patient management cycle.

14. The method of claim 13, wherein the linking event data is diagnosis category data and the linked data are in the treatment category and the outcome category.

15. The method of claim 14, wherein the linked data include outcome score in the outcome category.

16. The method of claim 14, wherein the linked data include admission score and discharge score.

17. The method of claim 13, wherein the patient data is related to at least two of tasks including patient management, clinical outcomes tracking, healthcare research, training of healthcare professionals, fulfilling certification or accreditation requirements, clinical trials, quality improvement assessment, informed consent tracking, risk mitigation assessment, access to multimedia files linked to treatment events, data collection for export to other database systems, and billing.

18. The method of claim 17, wherein the patient data is related to at least three of the tasks.

19. The method of claim 13, further comprising storing symbolic codes to represent descriptors, wherein each symbolic code represents a descriptor in more than one language.

20. The method of claim 19, wherein at least one of the symbolic codes are created by a user storing the patient data.

21. The method of claim 13, wherein the patient data is stored for more than one provider.

22. A computer readable medium having stored therein a plurality of sequences of executable instructions, which, when executed by a processor, cause a healthcare data analysis system to:

receive selected patient data from data options in at least one category including diagnosis, treatment and outcome;

store the patient data with a unique patient identifier to relate the patient data within a data set, each data set being for a different patient,

store a linking event identifier for corresponding linking event data to link at least some of the patient data related to a patient management cycle.

23. The computer readable medium of claim 22, wherein the linking event data is diagnosis category data and the linked patient data are in the treatment category and the outcome category.

24. The computer readable medium of claim 23, wherein the linked patient data include outcome score in the outcome category.

25. The computer readable medium of claim 23, wherein the linked patient data include admission score and discharge score.

26. The computer readable medium of claim 22, wherein the categories further include at least two of past history, clinical presentation, anatomy, pathology, diagnostic study, clinic visit outcomes score, admission outcome score, discharge outcome score, complication, disability and cause of death.

27. The computer readable medium of claim 22, further including symbolic codes for at least some of the patient data related to at least two categories including diagnostic, clinical presentation, anatomy, pathology, and outcome.

28. The computer readable medium of claim 22, further including additional sequences of executable instructions, which, when executed by the processor further cause the system to perform at least two tasks of a group of tasks consisting of patient management, clinical outcomes tracking, healthcare research, training of healthcare professionals, fulfilling certification or accreditation requirements, clinical trials, quality improvement assessment, informed consent tracking, risk mitigation assessment, providing access to multimedia files linked to treatment events, export of collected data to other database systems, and billing.
