Abstract

The system and method disclosed herein provides an integrated and automated workflow, sensor, and reasoning system that automatically detects breaches in protocols, appropriately alarms and records these breaches, facilitates staff adoption of protocol adherence, and ultimately enables the study of protocols for care comparative effectiveness. The system provides real-time alerts to medical personnel in the actual processes of care, thereby reducing the number of negative patient events and ultimately improving staff behavior with respect to protocol adherence.

Claims

1. An apparatus comprising:

a processor and memory configured to implement a reasoning engine configured to subscribe to messages published by an information broker from an augmented state transition network encoding a protocol as a plurality of states corresponding to tasks and transitions between the tasks, the state transitions based on a probability distribution associated with at least one of a location or a trajectory of at least one of a monitored person or a monitored object in an area being monitored, wherein the probability distribution is to be converted into a likelihood of a deviation for the protocol to be monitored based on the states encoding the protocol, the reasoning engine to dynamically determine a protocol task violation based on deviation from a protocol state calculated using the messages, the reasoning engine triggering an alarm to report the deviation,

wherein the reasoning engine is instantiated by a request from the workflow and uses the protocol, protocol tasks, and a protocol state together to determine protocol compliance, and wherein the reasoning engine determines, using the messages and an ordered ontology for a domain, the protocol state formed from the messages using the ordered ontology based on i) a first state associated with an agent to perform an action, ii) a second state associated with an object that is a recipient of the action, and iii) a third state associated with an event that associates the action with the object and the agent, the ordered ontology enabling a processing of the protocol state and a comparison of the protocol state to identify the deviation based on an illegal state transition, the illegal state transition between states in the augmented transition network based on the likelihood of deviation and a spatiotemporal relationship between the protocol state and a second state of the augmented transition network.

2. The apparatus of claim 1, wherein the reasoning engine determines, over a plurality of observations, a pattern of protocol events and generates a notice for at least one of positive reinforcement of protocol compliance or task execution enhancement for protocol compliance.

3. The apparatus of claim 2, wherein the task execution enhancement includes providing in-situ feedback including the alarm for the deviation and a proposed response to address the deviation.

4. The apparatus of claim 1, wherein the protocol includes a continuous function monitoring protocol with respect to a care plan, the protocol derived from the care plan, and tasks derived from the protocol.

5. The apparatus of claim 1, wherein the illegal state transition identifies an anomalous task represented by a message that is converted into at least one of an alert, a pattern analysis, or an invocation of workflow change.

6. The apparatus of claim 1, wherein the reasoning engine includes a protocol reasoning engine, a task reasoning engine, and a state reasoning engine combining to generate at least one of a process optimization or a policy enforcement.

7. The apparatus of claim 6, wherein each of the protocol reasoning engine, the task reasoning engine, and the state reasoning engine subscribes to a topic hosted by the information broker to receive messages published by the information broker.

8. The apparatus of claim 6, wherein the protocol is associated with a finite state machine.

9. The apparatus of claim 1, further including artificial intelligence to work with the reasoning engine to determine the protocol state.

10. The apparatus of claim 1, wherein the ordered ontology defines a protocol and its elemental state spaces in a particular domain of application.

11. A non-transitory, computer-readable medium including instructions which, when executed by a processor, cause the processor to at least:

instantiate a reasoning engine by a request from a workflow, the reasoning engine to determine protocol compliance;

subscribe, via the reasoning engine, to messages published by an information broker from an augmented state transition network encoding a protocol as a plurality of states corresponding to tasks and transitions between the tasks, the state transitions based on a probability distribution associated with at least one of a location or a trajectory of at least one of a monitored person or a monitored object in an area being monitored, wherein the probability distribution is to be converted into a likelihood of a deviation for the protocol to be monitored based on the states encoding the protocol;

determine, by the reasoning engine using the messages and an ordered ontology for a domain, a protocol state formed from the messages using the ordered ontology based on i) a first state associated with an agent to perform an action, ii) a second state associated with an object that is a recipient of the action, and iii) a third state associated with an event that associates the action with the object and the agent, the ordered ontology enabling a processing of the protocol state and a comparison of the protocol state to identify a deviation from the protocol state based on an illegal state transition, the illegal state transition between states in the augmented transition network based on the likelihood of deviation and a spatiotemporal relationship between the protocol state and a second state of the augmented transition network;

determine, via the reasoning engine, a protocol task violation based on the deviation from the protocol state calculated using the messages and the ordered ontology; and

triggering an alarm to report the deviation.

12. The computer-readable medium of claim 11, wherein the instructions, when executed, cause the processor to determine, over a plurality of observations, a pattern of protocol events and generates a notice for at least one of positive reinforcement of protocol compliance or task execution enhancement for protocol compliance.

13. The computer-readable medium of claim 12, wherein the task execution enhancement includes providing in-situ feedback including the alarm for the deviation and a proposed response to address the deviation.

14. The computer-readable medium of claim 11, wherein the protocol includes a continuous function monitoring protocol with respect to a care plan, the protocol derived from the care plan, and tasks derived from the protocol.

15. The computer-readable medium of claim 11, wherein the illegal state transition identifies an anomalous task represented by a message that is converted into at least one of an alert, a pattern analysis, or an invocation of workflow change.

16. The computer-readable medium of claim 11, wherein the reasoning engine includes a protocol reasoning engine, a task reasoning engine, and a state reasoning engine combining to generate at least one of a process optimization or a policy enforcement.

17. The computer-readable medium of claim 16, wherein each of the protocol reasoning engine, the task reasoning engine, and the state reasoning engine subscribes to a topic hosted by the information broker to receive messages published by the information broker.

18. The computer-readable medium of claim 16, wherein the protocol is associated with a finite state machine.

19. The computer-readable medium of claim 11, wherein the instructions, when executed, implement artificial intelligence to work with the reasoning engine to determine the protocol state.

20. The computer-readable medium of claim 11, wherein the ordered ontology defines a protocol and its elemental state spaces in a particular domain of application.
