Abstract

A system and method for managing workflow is provided. The system includes one or more computer devices which execute workflow software to assign tasks to medical staff. The workflow software may be configured to assign tasks to persons on the medical staff based on a set of criteria including a path length determined by a shortest-path algorithm. The system may include portable wireless communication devices and an interactive voice recognitions (IVR) subsystem to permit persons on the staff to communicate information by voice to the computer devices via the portable wireless communication devices and to receive audio messages from the computer devices via the wireless communication devices. The workflow software may be configured to display a staff screen in which the displayed data is filtered by medical staff role and sorted by medical staff identification.

Claims

1. A computer-implemented method for managing workflow including assigning tasks to medical staff in a health care facility, the method comprising

receiving information indicating that a person on the medical staff has completed an assigned task,

ascertaining the person'"'"'s location in the healthcare facility,

executing a shortest-path algorithm to determine at least one path length between the person'"'"'s location and at least one other location associated with at least one other task that the person is capable of performing, and

assigning a new task to the person based on a set of criteria including the at least one path length and including an amount of time that a task has remained uncompleted, wherein a task that is farther away from the person is assigned to the person as the new task if it has remained uncompleted for a threshold amount of time despite the fact that the person is closer to at least one other location having an associated task, and wherein the new task assigned to the person is a task that is closest in location to the person if the threshold amount of time has not elapsed for any tasks that are farther away from the person.

2. The method of claim 1, wherein the at least one path length is indicative of an estimated amount of time for the person to travel from the person'"'"'s location to the at least one other location associated with the at least one other task.

3. The method of claim 1, wherein the at least one path length is indicative of an estimated distance between the person'"'"'s location and the at least one other location associated with the at least one other task.

4. The method of claim 1, wherein executing the shortest-path algorithm comprises executing Dijkstra'"'"'s algorithm.

5. The method of claim 1, wherein prior to executing the shortest-path algorithm, the healthcare facility is mathematically modeled such that a vertex is assigned to each of a plurality of locations throughout the healthcare facility and at least one edge condition is designated between each vertex and at least one other vertex.

6. The method of claim 5, wherein at least one of the edge conditions corresponds to an estimated time of travel between the associated vertices.

7. The method of claim 5, wherein at least one of the edge conditions corresponds to at least an approximate distance between the associated vertices.

8. The method of claim 5, wherein at least one of the edge conditions comprises a bidirectional edge condition.

9. The method of claim 5, wherein at least some of the locations to which vertices are assigned correspond to at least one of a room of the healthcare facility, a zone of the healthcare facility, a care unit of the healthcare facility, and a transition point in the healthcare facility.

10. The method of claim 9, wherein the transition point is associated with an elevator or a flight of stairs.

11. The method of claim 1, wherein receiving information indicating that the person on the medical staff has completed the assigned task comprises receiving information via an interactive voice response (IVR) system.

12. The method of claim 11, wherein receiving information via the IVR system comprises receiving voice information via a wireless communication device carried by the person.

13. The method of claim 11, wherein receiving information via the IVR system comprises receiving voice information via a telephone of the healthcare facility.

14. The method of claim 1, wherein ascertaining the person'"'"'s location in the healthcare facility comprises ascertaining the person'"'"'s location based on a wireless signal received from a portable device carried by the person.

15. The method of claim 14, wherein the portable device comprises a badge worn by the person.

16. The method of claim 1, wherein ascertaining the person'"'"'s location in the healthcare facility comprises associating the person'"'"'s location with a monitoring station at which the person enters the information indicating that the person has completed the assigned task.

17. The method of claim 1, wherein the set of criteria includes whether the person is in possession of a particular type of medical equipment.

18. The method claim 1, wherein the set of criteria includes a role that has been assigned to the person.

19. The method of claim 1, wherein the set of criteria includes an amount of time that a patient or a piece of equipment has been waiting to be transported from one location to another.

20. The method of claim 1, wherein ascertaining the person'"'"'s location in the healthcare facility comprises receiving data regarding the person'"'"'s location from a locating and tracking system.
