A Review of Surgical Instrument Tracking (SIT) Deployments At Point-Of-Care

Updated: Jun 29

A review of return on investment (ROI) and return on experience (ROE) for point-of-care RFID surgical instrument tracking projects with four healthcare providers.

The case for tracking at Charité-Universitätsmedizin Berlin

The cost of manual instrument tracking was a primary driver for Charité-Universitätsmedizin Berlin, recognized as Germany’s best hospital. The time and cost of tracking 300,000 surgical instruments were growing at an unsustainable rate. In order to properly service and document instrument lifecycles, the hospital needed a technology that could bypass the identification and reading limitation inherent in contaminated instruments, while ensuring seamless tracking operations in the Central Sterile Supply department both before and during sterilization.

In 2016, the hospital began deploying Xerafy’s autoclavable RFID tags to track instruments. Any doubts staff had about the ability of the tags to function through multiple sterilizations were quickly put to rest through rigorous pre-deployment testing.

"We were able to test all the treatment processes that were used throughout the usual life cycle in test scenarios. There were no problems." - Sadmir Oasmancevic, Head of CSSD

The tags’ performance was established over 1,000 sterilization cycles, including exposure to chemicals, mechanical stress during transport, and material expansion during high temperatures. The biocompatible glue used to adhere the tags to the instruments withstands contact with blood-, saline- and iodine-containing substances.

Most importantly, the usability of the retrofitted instruments was not impaired, and suppliers were able to confirm the instruments still met existing certifications.

Xerafy’s technology will be a key component of the new Charité Facility Management building to open in 2017.

A Solution To Rising Operational Costs - Deployment at HRAEI Hospital of Ixtapaluca

At HRAEI Regional Specialty Hospital of Ixtapaluca in Mexico, manual surgical instrument counting often resulted in miscounts or missing assets. The 246-bed hospital with 13 surgical rooms serves a community of five million people.

What’s more, the sterilization procedures in place at the hospital involved the use of sandblasting to remove deposits from instruments because of the high mineral content of the local water supply.

"We urgently needed a solution for the high cost of managing our surgical instruments and operation workflow." - Jorge Mario Lopez Arango, General Manager

The hospital deployed Xerafy’s autoclavable XS and XXS tags after performing extensive tests throughout 1,000 autoclave cycles. Now, 97% of the surgical tools in use at the hospital are tracked using RFID.

The hospital staff uses handheld RFID readers to scan the tags and communicate the data to Android tablets during sterilization, during the building of surgical kids, and prior to each operating room procedure.

The instruments are counted within seconds while remaining in their sterile packaging. This has saved time and reduced the risk of infection.

Sterilization, Proven - RFID tracking at Columbia University’s College of Dental Medicine

A shift in sterilization processes led Columbia University’s College of Dental Medicine to an RFID solution.

One of the country’s leading dental schools, Columbia shifted from student-owned to school-owned instruments in order to centralize management and sterilization. That meant the school was now responsible for processing as many as 300 instrument kits daily. 

The school needed a reliable, cost-effective solution to improve patient safety by ensuring proper sterilization procedures were followed, and to better manage dental instruments for its students. The solution had to be durable, work on steel instruments, be compact enough to tag very small items, and still overcome the limitations of manual barcode scanning.

Using a mix of Xerafy XS, Pico, and Slim Trak tags, the school has tagged more than 20,000 dental instruments and 1,700 instrument kits.

"Using RFID, we will be able to prove that an item went into an autoclave for a certain amount of time and at a certain temperature." - Phil Jennette, Assistant Director of Special Projects

The school has been able to maintain accurate sterilization data for each instrument and cassette. Strategically positioned automated readers alert staff and prevent cassettes with missing instruments or instruments that have not been properly sterilized from being used, while automating maintenance and sharpening schedules.

"This type of technology allows for complete and accurate tracking of each instrument we use from the time it is dispensed through its utilization, processing, sterilization and return to storage." - Steven M. Erde, PhD, MD, Chief Information Officer 

31,000 OR hours saved over 12 months - Rigshospitalet Copenhagen

Labor savings were at the forefront of an RFID pilot test at Rigshospitalet Copenhagen in Denmark, where using RFID for instrument tracking could save 31,000 hours per year in unnecessary time spent manual tracking assets.

The hospital, which performs some 75,000 surgeries annually, wanted to free up time for better treatment and service to patients while optimizing workflows in its central sterile supply departments (CSSD) and surgical theaters.

Rigshospitalet needed RFID tags small enough to use on surgical instruments, but still reliable enough to provide a good read range on metal devices.

Using Xerafy’s tags, Rigshospital became the first in the world to pilot UHF RFID for surgical instrument tracking, tracking, and tracing all functions related to surgical instruments – from the operating room to cleaning and storage – with a single system.

Using the solution, up to 80 instruments can be counted at once, in seconds, with full accuracy.

The tags not only perform well on the metal instruments, but can withstand more than 1,000 autoclave processes, including exposure to high temperatures, harsh chemicals, and pressure. The tags are also small enough that they do not affect the balance of the instruments or how surgeons use them.

"RFID UHF technology provides unparalleled speed and accuracy advantages compared to barcode and other RFID technologies for tracking surgical instruments." - Dr. Henrik Eriksen, Project Director
