Passive tracking of linac clinical flow using radiofrequency identification technology.
This study reports implementation of a passive RFID system to passively track patient flow in a radiation therapy clinic using readers/antennae in linac vault areas. Across 4302 treatment fractions from 144 patients, the system achieved about 70% read reliability and enabled comparison of median in-vault treatment times by machine and treatment type. The authors conclude the approach warrants further development and may support ongoing workflow analysis to improve efficiency and safety.
Key points
- Passive RFID transponder cards were used to collect entry/exit timestamps for linac vaults.
- Data were analyzed for 4302 fractions from 144 patients over a 10-month period.
- Approximately 70% RFID read reliability was achieved with minimal staff training.
- Median vault times differed between the two linacs (TrueBeam vs iX) with reported statistical significance.
- Median vault times also differed by treatment type (RapidArc vs IMRT) and by 3D versus modulated delivery.
- The authors note challenges with automatic remote reading but suggest the system supports ongoing workflow monitoring.
