Abstract

A clinical decision support system (CDSS) includes a CDSS module (20) comprising a digital processing device (10) configured to store patient data (34) and a clinical guideline (22). The clinical guideline comprises connected nodes representing clinical workflow events, actions, or decisions, wherein contiguous groups of the nodes are grouped into care phases (40). The CDSS module is configured to associate patient data with patient care phases selected from the care phases of the clinical guideline, and determine patient care phase time intervals for the patient care phases based on acquisition date information for the patient data associated with the patient care phases. The selected patient care phase may be a care phase associated with a clinical guideline node associated with the new patient data, or may be a patient care phase that is consistent with the acquisition date for the new patient data.

2. The apparatus as set forth in claim 1, further comprising:

a display device (14) ;

wherein the CDSS module (20) is further configured to display a patient data timeline on the display device with the patient care phase time intervals delineated in the displayed patient data timeline.

3. The apparatus as set forth in claim 1, wherein the apparatus further comprises:

a user input device (12);

wherein the CDSS module (20) is further configured to;

receive new patient data and an acquisition date for the new patient data via the user input device;

associate the new patient data with a patient care phase selected from the care phases (40) of the clinical guideline (22); and

create or update a patient care phase time interval for the patient care phase associated with the new patient data based on the acquisition date for the new patient data.

4. The apparatus as set forth in claim 3, wherein:

the CDSS module (20) is configured to receive;

an associated node for the new patient data, and

the new patient data and the acquisition date for the new patient data; and

the COOS module selects the patient care phase-associated with the new patient data as a care phase into which the associated node is grouped.

5. The apparatus as set forth in claim 3, wherein the CDSS module (20) selects the patient care phase associated with the new patient data as a patient care phase having a patient care phase interval consistent with the acquisition date for the new patient data.

6. The apparatus as set forth in claim 1, wherein the CDSS module (20) is configured to determine the patient care phase time intervals for the patient care phases such that no more than two patient care phase time intervals overlap at any point in time.

7. The apparatus as set forth in claim 1, wherein the CDSS module (20) is configured to determine the patient care phase time intervals for the patient care phases such that none of the patient care phase time intervals overlap at any point in time.

8. The apparatus as set forth in claim 1, wherein the CDSS module (20) is configured to determine the patient care phase time intervals for the patient care phases such that each patient care phase time interval includes all acquisition dates for the patient data associated with the patient care phase.

9. A method comprising:

storing patient data in a clinical decision support system (CDSS) employing a clinical guideline (22) comprising a directed graph of nodes representing a clinical workflow, wherein contiguous groups of the nodes are grouped into care phases (40);

associating stored patient data. (34) with patient care phases selected from the care phases of the clinical guideline; and

constructing patient care phase time intervals for the patient care phases such that (i) each patient care phase time interval includes the acquisition time or acquisition times of an patient data associated with the patient care phase and (ii) no point in time is included in more than two patient care phase time intervals.

10. The method as set forth in claim 9, wherein the patient care phase time intervals for the patient care phases are constructed such that (ii′

) no point in time is included in more than one patient care phase time interval.

11. The method as set forth in claim 9, wherein at least some patient data (34) have associated nodes and patient data having an associated node has as its patient care phase the care phase of the associated node.
