Abstract

Interoperability across two or more heterogeneous clinical medical error taxonomies can be improved by associating categories in various taxonomies with one or more categories in a master taxonomy. These associations can be expressed using a unique identifier, e.g., a number that identifies one or more categories in the master taxonomy. Various aspects of the associations and/or one or more master taxonomies can be modified by users of a system employing embodiments of the technologies described herein. Searches of clinical medical error records can also be aided using the technologies described herein.

Claims

1. A computer system comprising computer-executable instructions stored on one or more computer-readable storage media, the instructions comprising:

a first software component configured to receive user-provided descriptions for at least a first original taxonomy and a second original taxonomy for classifying clinical medical errors, the at least first and second original taxonomies comprising heterogeneous clinical medical error categories;

a second software component configured to generate associations of unique identifiers with the categories of the first original taxonomy and the categories of the second original taxonomy, the unique identifiers corresponding to standardized categories of a master clinical medical error taxonomy, the original taxonomies being created independently of the master taxonomy, the unique identifiers being alpha-numeric codes subdivided into a plurality of blocks of one or more characters, the blocks representing nodes at different levels of categorization within the master taxonomy;

a third software component configured to generate a mapping of the first and second original taxonomies to one another, the mapping comprising correlating categories of the first original taxonomy with categories of the second original taxonomy that are associated with common unique identifiers;

a fourth software component configured to receive user-provided changes to relationships between one or more of the nodes of the master taxonomy with respect to one or more other of the nodes of the master taxonomy;

a fifth software component configured to modify the unique identifiers of the master taxonomy in response to the received user-provided changes to the relationships between the nodes of the master taxonomy;

a sixth software component configured to, in response to modifications of the unique identifiers, receive user-provided modifications to the associations of the unique identifiers of the master taxonomy with the categories of the first original taxonomy and the categories of the second original taxonomy; and

a seventh software component configured to update the mapping of the first and second original taxonomies to one another based on the received user-provided modifications of the sixth software component.

2. The system of claim 1, wherein modifying the unique identifiers of the master taxonomy comprises changing the characters of the blocks that represent the nodes.

3. The system of claim 1, wherein the leftmost block identifies the master taxonomy, the next block to the right identifies a node at a highest level in the master taxonomy, and the rightmost block identifies a node at a lowest level in the master taxonomy.

4. The system of claim 1, further comprising a set of one or more rules for managing data in the second and third software components.

5. The system of claim 1, wherein at least one of the first software component, the second software component and the third software component is configured to be executed on a first computer, and wherein at least one of the first software component, the second software component and the third software component is configured to be executed on a second computer.

6. The system of claim 1, further comprising a search software component configured to search clinical medical error data based on the mapping of the first and second original taxonomies to one another.

7. The system of claim 1, further comprising an administrative software component configured to regulate user-provided modifications from a plurality of non-administrator users.

8. The system of claim 7, wherein the administrative software component is configured to approve or deny the user-provided modifications based on authentication data received from users.

9. The system of claim 1, wherein the mapping of the original taxonomies to one another identifies one or more clinical medical error types common to the original taxonomies.

10. One or more computer-readable media comprising instructions that cause a computer to perform a method comprising:

receiving a description of a first clinical medical error category in a first clinical medical error taxonomy;

receiving a description of a second clinical medical error category in a second clinical medical error taxonomy, the first and second taxonomies having heterogeneous taxonomic structures;

creating a first association of the description of the first clinical medical error category with a unique identifier of a master clinical medical error category in a master clinical medical error taxonomy, the unique identifier being a numeric code subdivided into a plurality of blocks, each block representing a node at a different level of categorization within the master taxonomy, the first association being based on a similarity of subject matter encompassed by the first category and the master category, the first and second taxonomies being created independently of the master taxonomy;

creating a second association of the description of the second clinical medical error category with the unique identifier, the second association being based on a similarity of subject matter encompassed by the second category and the master category;

creating a third association of the first clinical medical error category and the second clinical medical error category based on the first and second associations;

storing an indication of the third association in one or more computer-readable media;

receiving a user-provided modification to the relationships between one or more of the nodes of the master taxonomy with respect to one or more other of the nodes of the master taxonomy;

modifying the unique identifier based on the modification to the relationships between the nodes of the master taxonomy;

receiving one or more user-provided modifications to the first and second associations based on the modifications to the unique identifier; and

updating the third association based on the received modifications to the first and second associations.

11. The one or more computer-readable media of claim 10, wherein the description of the first clinical medical error category in the first clinical medical error taxonomy is received over a network.

12. The one or more computer-readable media of claim 10, wherein the method further comprises automatically updating the third association at predetermined time intervals to incorporate user-provided modifications to the first and second associations received during the intervals.

13. The one or more computer-readable media of claim 10, wherein the user-provided modifications are received from one or more non-administrator users and the method further comprises updating the first and second associations based on the user-provided modifications after the user-provided modifications are approved by an administrator.

14. The one or more computer-readable media of claim 13, wherein the user-provided modifications are received from a plurality of non-administrator users.

15. The one or more computer-readable media of claim 10, wherein the method further comprises:

storing an indication of the first and second associations in one or more computer-readable media.

16. The one or more computer-readable media of claim 10, the method further comprising:

making a determination, based at least in part on the unique identifier, of whether a clinical medical error associated with the first clinical medical error category is considered to be similar to a clinical medical error associated with the second clinical medical error category; and

storing the determination in one or more computer-readable media.

17. One or more computer-readable media comprising instructions that cause one or more computers to perform a method comprising:

identifying one or more unique identifiers associated with respective master categories of a master taxonomy for classifying information in a field, the unique identifiers comprising a plurality of blocks of alpha-numeric characters, each block corresponding to a node at a different categorization level within the master taxonomy, the blocks from left to right identifying nodes in the master taxonomy with increasing depth;
