System and method for monitoring clinical activities
A monitoring system can be configured to monitor activities or actions occurring in clinical settings, such as hospitals. The monitoring system can improve patient safety. The system can use visual and/or other tracking methods. The system can detect and/or identify people in a clinical setting. The system can also track activities of the people, for example, to improve adherence to hygiene protocols.
1. A system for monitoring of hand hygiene compliance on a local network in a clinical room, the system comprising:
a first camera configured to capture first image data from a first viewpoint in the clinical room;
a first hardware processor in physical proximity to the first camera, the first processor configured to detect a person in an image frame from the first image data and assign a boundary box unique to the person, the first processor further configured to track movement of the boundary box in subsequent image frames from the first image data by associating a plurality of boundary boxes in consecutive image frames to a track created for the person by the first hardware processor in response to the plurality of boundary boxes in the consecutive image frames overlapping within a predetermined threshold;
a second camera configured to capture second image data from a second viewpoint in the clinical room; and
a second hardware processor in physical proximity to the second camera, the second processor configured to detect a hand hygiene activity from the second image data;
wherein the first and second processors are in electrical communication with each other, the first or second processor configured to determine whether the detected hand hygiene activity was performed by the person to whom the boundary box and the track is assigned, and wherein the first or second processor is configured to assign the same track to the detected person after the detected person has been temporarily invisible from a view of the first or second camera, and
wherein the first processor and/or the second processor are in electrical communication with a display device in the clinical room, the first and/or second processors configured to output an alert to the display device in the clinical room in response to the boundary box entering a patient zone without the second processor detecting a hand hygiene activity by the person to whom the boundary box and the track is assigned.
2. The system of claim 1 , wherein the first processor is configured to output an alert directly to the display device in the clinical room.
3. The system of claim 1 , wherein the first and second viewpoints are fixed.
4. The system of claim 1 , wherein the first camera faces an entrance of the clinical room.
5. The system of claim 3 , wherein the second camera faces a hand hygiene station.
6. The system of claim 5 , wherein the second camera faces downward at the hand hygiene station.
7. The system of claim 5 , wherein the hand hygiene station comprises a sink and/or a hand sanitizer dispenser.
8. The system of claim 7 , wherein the second processor is configured to detect a handwashing activity at the sink.
9. The system of claim 1 , comprising a third camera, wherein the third camera is configured to capture third image data from a third viewpoint in the clinical room.
10. The system of claim 1 , wherein the first processor is configured to assign a contaminated status to any person upon first detection of said person.
11. The system of claim 10 , wherein the first or second processor is configured to change a contaminated status of the person to a clean status upon detection of the person having performed the hand hygiene activity.
