An infrequent error that occurs during surgical procedures is the unintentional
retention of an instrument or sponge within a patient. This error can lead to
inflammation, obstruction, perforation, sepsis, and sometimes death. Despite the
safeguards that are employed within the operational room environment,
approximately 1 in 1500 surgical cases results in an object being left within a
patient.
We are developing ASSIST, an Automated System for Surgical Instrument and
Sponge Tracking to increase the safety of surgical procedures. In ASSIST, RFID
(Radio Frequency IDentification) technology is used to detect and uniquely
identify the presence of each surgical item at various stages during surgery. The
use of low frequency RFID enables reliable detection of tags even when soaked
in body fluids, in the vicinity of metallic objects such as surgical tools, or inside a
patient's body. A software-based component keeps track of every item, and
