In one embodiment, a process may obtain sensor data associated with a motion event captured by a wearable device. The process may identify, using the sensor data as input to one or more machine learning-based classifiers, a hand hygiene protocol associated with the motion event. The process may recognize, from the sensor data associated with the motion event, a deviation from a step of the hand hygiene protocol. The process may provide, based on recognizing the deviation, remediation instructions to achieve compliance with the step of the hand hygiene protocol.
