Abstract

Healthcare workflow processes are extremely complicated. Surveys and interviews are a common but a rather expensive way of conducting process research. This paper elaborates a new approach based on wireless technologies for data gathering of healthcare processes. We have developed an automatic process measurement system for collecting real-time process data. The system consists of mobile devices that detect Bluetooth sensors. The identifiers of the detected sensors are stored in log files. We apply the system to three Linux-based platforms. Empirical tests are conducted to evaluate the performance of the system. The Radio Signal Strength Indicator (RSSI) is used to improve the accuracy of the data collected by the system.
