Abstract

A system and method for keeping, organizing and managing electronic records, comprising generating a first instance of data objects comprising data elements during a first encounter, the elements comprising a first instance identifier and temporal identifiers; linking a data object to a summarization reference with a pointer; creating an additional instance of data objects also comprising data elements comprising an additional instance identifier and temporal identifiers during a later encounter; and providing continuity for the first instance data objects over time. Continuity may be provided by tracking a relationship between the first instance data object and an additional instance data object and repointing the pointer to point between the summarization reference and the additional instance data object. The additional instance data object may be a revision of the first instance data object, and tracking may occur by back-linking the revision to the first instance data object.

Claims

1. A method for electronic record keeping, organizing and managing, comprising:

collecting visit level information for administrative use, said visit level information comprising data items representing at least one of the following;

demographic information, subjective information, objective information, assessment information and plan information;

collecting and maintaining a list of items relating to an individual;

assuming management of follow up items;

creating a revision history of said list of items over time;

implementing a privacy protocol;

providing a task-based workflow;

supporting secure data exchange; and

supporting resource-based tasking;

wherein the creating step includes;

linking a data item of information created during a first visit and a data item of information created during a second visit, directly or indirectly, using a pointer; and

designating the second visit data item as current;

wherein the linked data items are stored in a directed graph data structure.

2. A method according to claim 1, wherein said implementing step further comprises:

providing an audit of database activity;

providing robust security;

providing role-based record access; and

encrypting sensitive data.

3. A method according to claim 1, wherein the providing step includes:

creating a task at the completion of said visit.

4. A method according to claim 1, wherein the providing step includes:

producing a task calendar of events, functional data review and task production.

5. A method according to claim 1, wherein the providing step includes:

using a new or existing task list to trigger a task or reminder.

6. A method according to claim 1, wherein the task-based workflow is governed by Arden-syntax rules.

7. A method according to claim 1, wherein completing a task triggers the creation of one or more additional tasks.

8. A method according to claim 1, wherein a task is created by evaluating the current state of a patient.

9. A method according to claim 1, wherein the task-based workflow includes a plurality of tasks arranged hierarchically.

10. A method according to claim 9, wherein a parent task is considered satisfied when all child tasks are satisfied.

11. A method according to claim 1, the providing step including:

producing a calendar of patient care events; and

proceeding to data review.

12. A method according to claim 1, wherein a task list for one patient triggers a task for another patient.

13. A method according to claim 1, further comprising:

instantiating data in the directed graph data structure in a relational database.
