1. An apparatus comprising:
- a processor and memory configured to implement an augmented state transition network encoding a protocol as a plurality of states corresponding to tasks and transitions between the tasks forming a protocol sequence,the state transitions based on a probability distribution derived from a model of the protocol sequence associated with at least one of a location, a geometric surface point, or a trajectory of at least one of a monitored person or a monitored object in an area being monitored,wherein the probability distribution represents a likelihood of deviation for the protocol to be monitored based on the states encoding the protocol, the processor to dynamically determine a protocol task violation based on a deviation from a protocol state and output a report of the deviation,andwherein the processor is to determine the protocol state 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 processor to process 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 probability distribution representing the likelihood of deviation and at least one of a spatial or a temporal relationship between the protocol state and a second state of the augmented transition network.

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.
