It happens all too often: a patient wakes up from surgery to be advised all has gone well. But then weeks, months and sometimes years later, the patient starts experiencing symptoms such as pain or vomiting which do not seem to be related to any trauma or illness. Doctors can find no explanation for the symptoms and, in some cases, the patient is treated as if the problem is in their head. Only after the symptoms become acute or when the patient and doctor are relentless in their search for an answer is the real culprit revealed: a retained object from the surgery.
Retained objects come in many forms including scalpels, clamps, scissors, tubing, needles. But, the most common is sponges which account for about two-thirds of all retained objects. The most common method for tracking sponges is a simple manual count. But clearly, that old-fashioned method is not effective as it should be because each year roughly 4,000 cases of retained surgical items are reported in this country.
Technology exists which is much better at preventing retained object cases. Sponges can be tracked through the use of a radio-frequency tag. The tag itself is tiny — roughly the size of a grain of rice and is embedded in each sponge. At the end of the surgery, the system can detect if any sponges were forgotten inside the patient. In a study conducted at the University of North Carolina at Chapel Hill, this system prevented 23 sponges being left in surgical patients over the course of just 11 months. And the cost for this added patient security? About $10.00 per procedure. The additional time to use the system before closing the patient? About 12 seconds.
