Abstract

A system and a method are described for allowing a user to generate a timeline and display patient data with varying time intervals. The time intervals can range from a few minutes to several hours. By allowing a user to select start time and end time when a time interval change occurs, the time interval change is applied to a selected portion or duration of the timeline rather than the full length. Also multiple time intervals may be selected and applied to the patient data.

Claims

1. A method for processing medical information, comprising the steps of:

enabling a user via a user interface display image, to select a first periodic time interval for periodically displaying patient data in a first time duration on a timeline, said first periodic time interval being different from a second periodic time interval for periodically displaying patient data on said timeline in a second time duration exclusive of said first time duration;

enabling a user to select a start time and end time identifying said first time duration within said timeline;

acquiring first and second patient data substantially at said first and second periodic time intervals and in said first and second time durations, respectively;

displaying said acquired first and second patient data at said first periodic time interval during said first time duration in a display image together with data representing said timeline; and

displaying said acquired first and second patient data at said second periodic time interval during said second time duration in a display image together with data representing said timeline.

2. The method of claim 1 wherein

the step of enabling a user to select a time interval further comprises a step of displaying a list of selectable time intervals.

3. The method of claim 2 wherein the list of selectable time intervals comprises

at least one or more of the following time intervals:

1) 3 minutes;

     2) 5 minutes;

     3) 15 minutes;

     4) 30 minutes;

     5) 1 hour;

     6) 2 hours; and

     7) 4 hours.

4. The method of claim 1 wherein

the step of enabling a user to select a start time further comprising a step of displaying a list of allowable start time choices based on a predetermined rule.

5. The method of claim 4 wherein

the step of enabling a user to select an end time further comprising a step of displaying a list of allowable end time choices based on a predetermined rule.

6. The method of claim 4 wherein the predetermined rule comprises one or more of the following restrictions:

1) the allowable start time occurs on the hour;

     2) the allowable start time currently appears on an associated flow sheet;

     3) the allowable start time occurs on an even hour, when the selected time interval is 2-hour; and

     4) the allowable start time needs to be in the set of (0, 4;

00, 8;

00, 12;

00, 16;

00 and 20;

00), when the selected time interval is 4-hour.

7. The method of claim 1 further comprising

enabling a user via a user interface display image, to select said second periodic time interval for periodically displaying patient data in said second time duration.

8. The method of claim 7 wherein the second time interval is selectable by a user.

9. The method of claim 4 further comprising a step of displaying a default start time.

10. The method of claim 5 further comprising a step of displaying a default end time.

11. The method of claim 1 further comprising:

determining if the selected time interval affects data that has been acted on via the patient data screen; and

disallowing the change to the selected time interval for the timeline in response to the above determining step.

25. The method of claim 11 wherein the data has been acted on by at least one of the following actions:

1) data has been changed by a user;

     2) data has been accepted by a user; and

     3) data has been entered by a user.

12. A system for processing data, comprising:

a processor for

enabling a user, via a user interface display image, to select a first periodic time interval for periodically displaying patient date in a first time duration on a timeline, said first periodic time interval being different from a second periodic time interval for periodically displaying patient data on said timeline in a second time duration exclusive of said first time duration;

enabling a user to select a start time and end time identifying a said first time duration within the timeline;

acquiring first and second patient data substantially at said first and second periodic time intervals and in said first and second time durations, respectively;

applying the selected time interval to the timeline for the duration identified by the selected start time and end time; and

a display for displaying said acquired first and second patient data at said first periodic time interval during said first time duration in a display image together with data representing said timeline and displaying said acquired first and second patient data at said second periodic time interval during said second time duration in a display image together with data representing said timeline.

13. The system of claim 12 wherein

the time interval is selected by using a displayed list of selectable time intervals.

14. The system of claim 13 wherein the displayed list of selectable time intervals comprises at least one or more of the following time intervals:

1) 3 minutes;

     2) 5 minutes;

     3) 15 minutes;

     4) 30 minutes;

     5) 1 hour;

     6) 2 hours; and

     7) 4 hours.

15. The system of claim 12 wherein the start time is selected by using a displayed list of allowable start time choices based on a predetermined rule.

16. The system of claim 12 wherein the end time is selected by using a displayed list of allowable end time choices based on a predetermined rule.

17. The system of claim 15 wherein the predetermined rule comprises one or more of the following restrictions:

1) the allowable start time occurs on the hour;

     2) the allowable start time currently appears on an associated flow sheet;

     3) the allowable start time occurs on an even hour, when the selected time interval is 2-hour; and

     4) the allowable start time needs to be in the set of (0, 4;

00, 8;

00, 12;

00, 16;

00 and 20;

00), when the selected time interval is 4-hour.

18. The system of claim 12 wherein the processor further enables the user, via a user interface display image, to select the second periodic time interval in the second duration.

19. The system of claim 18 wherein the second time interval is selected from a list of time intervals.

20. The system of claim 15 wherein the displayed list of allowable start time choices comprises a default start time.

21. The system of claim 15 wherein the displayed list of allowable end time choices comprises a default end time.

22. The system of claim 18 wherein the processor further allows the user to select a second start time and a second end time for the selected second duration.

23. A method of processing data, comprising the steps of:

receiving a time interval change request including a first periodic time interval for periodically displaying patient date in a first time duration on a timeline, the first periodic time interval being different from a second periodic time interval for periodically displaying patient data on said timeline in a second time duration exclusive of said first time duration;

determining allowable start time and end time choices in response to the time interval change request;

displaying default start time and end time;

displaying allowable start time and end time choices in response to another user request;

selecting a start time and end time identifying the first time duration from the displayed choices;

applying the first periodic time interval to the first time duration between the selected start time and end time;

acquiring first and second patient data substantially at the first and second periodic time intervals and in said first and second time durations, respectively; and

updating the acquired first and second patient data at the first periodic time interval during the first time duration in a display image together with data representing said timeline and updating the acquired first and second patient data at said second periodic time interval during said second time duration in a display image together with data representing said timeline in response to applying the time interval change.

24. The method of claim 23 wherein the data comprises a patient flow sheet.
