There are various levels of frequencies that can be set for wireless devices as well, so many times a solution could be using devices and RFIDs are on different frequencies and to rise above the “white noise” levels. Hospitals have a designated frequency for use, so sometimes having a chip system operating within another frequency for RFID use could be helpful when tracking equipment, etc. within the hospital for non patient care related items, in other words not directly tied to patient care but rather just for locating equipment and supplies. There are some systems already on the market that operate on their own, outside the hospital’s wireless network, but like everything else, it needs to be tested. BD
The wireless systems are used to tag and keep track of medical equipment like heart-testing machines, joint replacements and surgical staplers. They can help quickly locate devices that are elsewhere in the hospital and help prevent theft.
The technology also is viewed as a way to prevent drug counterfeiting, by embedding microchips in drug containers, and to prevent harmful medical errors by keeping tabs on devices used during surgery.
The results show that it's crucial for hospitals to test their wireless items before using them around equipment essential for keeping patients alive, said Dr. Erik Jan van Lieshout, a study co-author and critical care specialist at the University of Amsterdam's Academic Medical Center.
