Tracking Clinical Staff Behaviors in an Operating Room
Abstract
:1. Introduction
2. Description of the Behavior Assessment System
2.1. Motion Capture System
2.2. Inertial Measurement Units Wireless Network
- number of persons in the room,
- 2D position of the persons present in the room,
- door status (open/closed)
2.3. Data Acquisition
- textual comments from the operator through a guided user interface (GUI)
- static 3D positioning of key points in the surgical operating room: table corners, doors, etc.
- dynamic 3D positions of the objects tracked by the VICON
- dynamic data from the three inertial units installed on each door i
2.4. Data Processing
2.4.1. Door Event Extraction
2.4.2. Staff 3D Positions Pre-Filtering
- filter by pieces: if the time interval between two detected positions of the object exceeded a predefined duration, the trajectory was segmented.
- minimum points per time window: if the number of detected positions of the object points in a predefined time interval was less than a predefined number, the point was considered isolated and removed.
- 1D outliers in the different axes (x, y, z): the distance to the median was computed for each 1D point in a sliding time window; if the distance exceeded a determined value, the point was removed.
- norm outliers: the distance to the median was computed for the norm of each 2D point (x, y) in a sliding time window; if the distance exceeded a determined value, the point was removed.
2.4.3. Combination of Staff 3D Positions and Door Events
2.5. Ethics and Risk Assessment
3. Results
3.1. Illustrative Intervention
3.2. General Analysis
4. Conclusions
