Abstract

A hospital's ability to effectively deliver services requires a communication system that under rigorous time constraints can handle information about patients. A wireless transmission solution which links the positive patient identification with electronic medical records (EMR) is presented in this paper. Also, a prototype device based on IEEE 802.15.4 and RFID technologies was developed. Different RFID tags (patient, nurse, medical device) are retrieved by the RFID reader implemented into prototype. After successful identification sentence, the radio transponder starts sending the EMR data through access point to server, which will link them with patient ID information. All data can be referred, on real-time, by allowed personnel from any networked device in the hospital (PC, PDA, mobile, etc.). Employed identification procedures reduce significantly the risk of patient misidentification. Moreover, the implementation of 6LoWPAN protocol makes this solution technology independent and allows an easy transition to another wireless technology like WLAN or UWB. In this work, test regarding transmission factors and comparison with other wireless technologies were performed. These tests demonstrated that the 802.15.4 technology used in this prototype is not efficient enough. However, this solution combined with another wireless transmission technology can be utilized and can consequently improve hospital workflow.
