Medical Automated Asset Tracking
Categories: Medical SoftwareIn late August of 2005 Hurricane Katrina began a path of unparalleled destruction throughout the Gulf States, leaving tens of thousands of people homeless, and without hope of shelter, food, water, electricity or even basic medical care. Little did anyone know that within a day’s journey two massive military convoys laid waiting at the Naval Expeditionary Medical Support Command (NEMSCOM), a military medical warehouse facility located at Cheatham Annex, Virginia, ready to make way and render aid.
The convoys, outfitted with fresh water tanker trucks, generators, telescoping light stations, air conditioners, medical supplies, diesel fuel, food blankets, toiletries, shelters, portable bathroom facilities, mobile communication centers, ambulances, fire engines, cranes, and bull dozers laid waiting to respond. The call never came, despite the most valiant efforts of NEMSCOM’s Commanding Officer, CAPT Larry Arcement.
Disaster relief materials, like any material inventory assets, are only good if you know what you have, how many you have and where they are located. That is where automated asset tracking, utilizing automated identification technology (AIT), comes into play. Automated identification technology can come in a variety of forms ranging from highly sophisticated active and passive radio frequency identification (RFID) systems used by the vast majority of manufacturers today to its lesser known counterparts, consisting of Contact Memory Buttons, Iridium Tracking and Info Dot recognition systems. Regardless of the technology used they all share a common trait, the rapid identification and location of assets available.
In a highly dynamic medical environment, the identification and tracking of medical assets has become increasingly difficult. Perhaps no other military command has realized that more than NEMSCOM, which constructs and deploys fleet hospitals and numerous expeditionary medical facilities worldwide in response to military conflicts and humanitarian disasters. With more than $340 million dollars in medical assets located worldwide, optimum operational efficiency must be realized.
In 2004, in conjunction with the Navy AIT Project Office, NEMSCOM embarked on a series of initiatives to develop automatic identification and data capture (AIDC) technology to help manage medical material and provide total asset visibility. These projects reviewed the possible integration of AIDC into medical logistics business processes. NEMSCOM’s goal was to facilitate the collection of initial source data, and collect and pass the AIDC data to reduce processing times, improve inventory accuracy, increase production efficiency and enhance “total” asset visibility.
The first key initiative came in the form of surgical instrument identification. At the conclusion of a medical mission, expeditionary hospitals, consisting of tens of thousands of components, equipment, and supplies, are rapidly packed and returned to NEMSCOM for cleaning, repackaging and introduction into the next expeditionary medical platform build. Thousands of surgical instruments, which have no manufacturer markings or means of identification, are returned in boxes, barrels and footlockers. With more than 14,000 different types of medical instruments, made by a myriad of manufacturers, the process of trying to identify these instruments can be daunting.
The identification process required the skills of numerous senior medical technicians and countless hours of research, with each instrument requiring 15 to 30 minutes for identification. Even with these efforts, identification accuracy was limited to approximately 60%. Many of the surgical instruments cost several thousand dollars, have limited availability and require significant lead times to obtain, which makes the correct identification of current assets vital.
In an effort to dramatically increase medical asset identification, NEMSCOM embarked on a pilot program to develop effortless recognition of all medical assets. The marking system needed to be highly accurate, durable, inexpensive, easy to operate and needed to increase production efficiency. The end result of this effort was the implementation of info dots in conjunction with a newly developed asset tracking software program called MAAT (Material Automated Asset Tracking).
The info dot is a two dimensional data matrix mark, available as a 3 mil and 10 mil barcode, which is less than a tenth of the size of most common barcodes. This DataMatrix barcode is a small, flexible and unobtrusive label that is virtually indestructible. More than 60% of the label can be torn away and still allow for a 100% percent read rate. It is easily attached to any surface using a pressure-sensitive acrylic adhesive. The info dot has a high degree of redundancy, making it highly reliable, and its symbology can be read with charged couple device scanners. The info dot can withstand temperatures of nearly 500°F short-term and nearly 400°F over a long-term period. It resists solvents, caustics, and acids as well as oils, grease, fuels and salts.
