  • New barcode technology coming out of MIT

    Engadget: “Since barcodes are the sign of the devil (must be true, we read it on the interwebs) it’s no surprise thateveryone wants to replace ’em. QR codes have been quite popular, allowing people and companies to tag their stuff with colorful decals filled with bits and bytes, and of course RFID tags are still going strong, but a team of researchers at MIT has come up with something better: Bokode. It’s effectively a tiny little retroreflective holograph that is just 3mm wide but, when a camera focused to infinity sweeps across it, the Bokodes become clear and appear much larger, captured in the video below. In this way they can contain “thousands of bits” of data and, interestingly, show positional information too, meaning the camera knows where in 3D space it is in relation to the tag. This, of course, has hundreds of potential applications ranging from grocery shopping to augmented reality, and should lead to new and exciting ways for scholars to interpret/misinterpret Revelations.” – I first saw this information yesterday in a link to a BBC News article that was floating around Twitter. I can see use for such barcode technology in pharmacy. In the BBC article, Dr. Mohan (one of the MIT researchers) makes a comment that while standing in front of thousands of books “You could take a picture and you’d immediately know where the book you’re looking for is.” Now, replace the word ‘book(s)’ with ‘drug(s)’ and you will understand my interest. More information can be found here.

  • Healthcare vs. consumer tech, who’s more advanced?

    I spend a lot of time on the internet, probably too much time.  My recent readings resulted in a raised eyebrow when I spotted two articles in particular; one for a new touch-screen anesthesia system from McKesson and the other for a touch-screen coca-cola fountain drink dispenser.

  • Cool Technology for Pharmacy

    Healthcare IT Consultant Blog: “VeriChip Corporation Outlines Current Applications and Potential Future Applications for its First-of-a-Kind Implantable RFID Implantable Microchip - VeriChip Corporation, a provider of radio frequency identification (RFID) systems for healthcare and patient-related needs, today provided additional comments regarding its VeriMedâ„¢ Health Link patient identification system following the recent passage of a bill by the Pennsylvania House of Representatives banning forced microchip implantation in humans, and also outlined its current and potential future applications for its RFID implantable microchip. The VeriMed Health Link system was cleared by the FDA in 2004 as a Class II medical device and is the first and only implantable microchip cleared by the FDA for patient identification. “

  • Open source software for hospital use.

    HIT Consultant Blog: “…But bringing state-of-the-art technology to health care is expensive, often running well into eight figures. Still, there are ways to keep the cost down and also provide excellent care. Forbes caught up with David Whiles, CIO of Midland Memorial Hospital in Midland, Texas, to look at ways to save huge amounts of money without sacrificing quality…So what did you do? – We came across the VistA (Veterans Health Information Systems and Technology Architecture) system, which was developed by the Veterans Administration. That’s used by all the 160-plus VA hospitals in the United States, plus all of their outpatient ambulatory clinics. It’s been in use by the Veterans Administration for more than 20 years. It’s a very mature system. It’s won a number of accolades from the Institute of Medicine.” – Imagine that, open source software being used in a hospital. The software may be a few years old, but thinking outside the box and implementing open source software in a hospital sure sounds cutting edge to me. Where do I apply?

  • RFID vs. barcode

    Barcode.com: “RFID, or radio frequency technology, uses a tag applied to a product in order to identify and track it via radio waves. The 2 parts that make up the tag are an integrated circuit and an antenna. While the circuit processes and stores information, the antenna transmits signals to the RFID reader, also called an interrogator, in order to interpret the data in the tag. In contrast, a barcode is an optical representation of data that can be scanned and then interpreted. The data is represented by the width and spacing of parallel lines, and are often used in POS applications, in addition to tracking objects throughout the supply chain.” – The article goes on to give the advantages of both technologies. The more I read about RFID technology, the more interested I become. While the technology hasn’t really caught fire in health care, I think the utility of RFID demands further investigation.

  • Apple patent details RFID tag reader.

    9to5mac.com: “RFID reader built into the screen?  We’re not quite sure why they’d need to do this (as opposed to putting the reader somewhere else in the device) but Apple has put a patent application on this.” – In addition, the US Patent and Trademark Office lists the following: “The efficient incorporation of RFID circuitry within touch sensor panel circuitry is disclosed. The RFID antenna can be placed in the touch sensor panel, such that the touch sensor panel can now additionally function as an RFID transponder. No separate space-consuming RFID antenna is necessary. Loops (single or multiple) forming the loop antenna of the RFID circuit (for either reader or tag applications) can be formed from metal on the same layer as metal traces formed in the borders of a substrate. Forming loops from metal on the same layer as the metal traces are advantageous in that the loops can be formed during the same processing step as the metal traces, without requiring a separate metal layer.” – I can think of several uses for an iPhone with a built in RFID Tag reader, it can already read barcodes. The iPhone just keeps getting cooler and cooler.

  • Barcodes on patient wristbands.

    wristbandbarcodeBarcode.com: “Often times, information that Hospital administrators would like to include in the barcode is far too much in relation to the wristband space. While 1-D barcodes cannot always fit all of the information, they can be scanned by all types of barcode readers, unlike 2-D barcodes which can fit more information, but require a 2-D capable scanner. In addition, when the end of the barcode curve around patients wrists, it is difficult to scan, thus, it is necessary to choose a barcode symbology that will fit on the flat part of the wristband, but also hold all of the necessary information. Rather that choosing a UPC code, which is commonly used in retail applications, it would be wise to choose a dense barcode symbology, such as Code 128, which can hold a lot of information in a small amount of space.“ - Wristbands are a popular item for discussion in any barcode medication administration (BCMA) project. They’re just not user friendly. Even though 2-D barcodes require an upgraded scanner, I prefer them because of their small footprint. Their size allows multiple copies of the same barcode to be placed on the wristband in several strategic locations for easy access. The difficulty associated with scanning a patient wristband is one more reason why RFID may be worth a second look.

    RFID refers to small electronic devices that consist of a small chip and an antenna. They are capable of carrying quite a bit of information. To retrieve the information an RFID device must be scanned much like a barcode. While barcodes require a “line of sight” to be recognized by the scanner RFID labels can be scanned independent of position relative to the scanner and may be read up to 20 feet (or more) away.

    RFID is an interesting alternative to barcoding for medication tracking and administration. The advantages are their ability to carry increased amounts of information and the relative ease of scanning mentioned above. It is unclear why RFID hasn’t become more main stream, but one reason could be the relative cost when compared to a traditional barcoding system. RFID would certainly make tracking inventory a little easier.
