  • KoamTac adds scanner cases for Samsung Galaxy SIII and Samsung Note 2

    KoamTac makes some pretty cool BlueTooth barcode scanners. I’ve used their KDC300i imager with an iPod touch. It’s small, light and fast.

    Historically KoamTac has been almost exclusively aimed at Apple equipment, i.e. iPhones, iPod touches and iPads. It’s nice to see that they’re including other popular smartphones as well. I’m particularly excited to see that they have a case for the Samsung Note 2. The Note 2 would make an interesting device if paired with one of the KoamTac BlueTooth scanners, especially when you consider the additional functionality of the S Pen. Pretty cool.

  • Saturday morning coffee [October 13 2012]

    So much happens each and every week that it’s hard to keep up sometimes. Here are some of the tabs that are open in my browser this morning along with some random thoughts….

    The coffee mug to the right is from The Sixth Floor Museum at Dealey Plaza in Dallas, Tx. My family and I spent some time there during our summer vacation in Texas. One of the things I really wanted to do in Dallas was visit Dealey Plaza and the site where JFK was assassinated. Well, I finally got that chance as my family and I spent some time walking around the plaza area, visiting the location of the assassination and spending a little time at the book repository and museum. JFK is one of the few men in history that I would have liked to have met in person.

    Taken 2 was #1 at the box office last weekend. My wife and I saw it last Saturday. Not bad. If you decide to go see it make sure you don’t want a good story line or incredible acting range. Just enjoy the senseless violence and be entertained. Hotel Transylvania was #2 at the box office. I saw that last night with my wife and youngest daughter. Good, clean humor. Worth seeing especially if you have little ones.

  • Cool Pharmacy Tech – Real time volume detection in syringes

    I received the Tweet below last night from Denis Lebel. The link took me to a YouTube video that demonstrates the use of a camera and software to determine the volume inside a syringe. It’s really cool.

    I had an idea like this about 6-8 months ago. I talked it over with a colleague and they said it couldn’t be done. Well it seems the smart folks at Scorpion Vision Software did what couldn’t be done. Surprise! Denis said they’ve been working on it for about a year. Congratulations are in order as I think this is brilliant.

    Translated text from the video description: “This video shows a proof of concept that allows the detection volume of syringes in real time thanks to the vision software. This real-time detection, combined with the reading of bar code products can be an important addition to the quality control of the preparation of intravenous medications in sterile chamber in pharmacies of health facilities.

    In this video we demonstrate how the Scorpion vision software software identifies the”bar code” that identifies the type of syringe used, the position of the piston and thesyringe body in 3D space and then estimating the volume contained in the syringe.”

  • Call for abstracts, speakers for the 2012 unSUMMIT

    The 2012 unSUMMIT will be held on May 2-4, 2012 at the Hyatt Regency Orange County in Anaheim, California. Heck, that’s right in my backyard. Looks like I’ll be attending.

  • Socket announces latest Bluetooth barcode scanner

    chs7xscannermobihealthnews: “Socket Mobile announced this week the availability of its latest Socket Bluetooth Cordless Hand Scanner (CHS) Series 7, a barcode scanner with medical applications which has been Apple-certified as a “Made for iPad, iPhone, iPod” accessory.

    “This is the best performing barcode scanner for developers who are creating applications incorporating barcode scanning for the Apple iOS,” stated Samantha Chu, data collection product manager at Socket Mobile, in a press release. “There are numerous applications that stand to benefit from barcode scanning in a range of vertical markets, and we believe the CHS 7Xi provides the Apple developer community with a level of control and data integrity that didn’t exist previously.”

    I’ve mentioned the CHS Series 7 scanners before. They really are neat little devices; small, quick and accurate.

    Another scanner worth mentioning in this category is the Koamtac KDC200. I’ve used the KDC200 and it’s a pretty slick scanner as well.

  • The weakest link in building a safer medication use model

    I’ve just spent four days at the ASHP Summer Meeting in Denver, CO. The meeting offered a nice variety of topics, but seemed to focus on medication safety and informatics more this year than in the past. In fact, this is the first year that ASHP has offered a medication safety tract at one of their meetings.

    I avoided the more traditional sessions on therapeutics, choosing instead to focus on the informatics and medication safety sessions. Based on the information presented it was obvious to me that these two disciplines are intimately linked. After all, the idea behind much of the technology we use in healthcare today is to improve patient safety.

  • Cool Pharmacy Technology – Codonics SLS Safe Label System

    Labeling syringes has always been difficult for anesthesiologists in the OR. It must be because they never seem to get it right. If you don’t believe me, just look at the image below. These drugs were found during routine inspection of an OR suite. Well that’s all changed now with the Codonics SLS Safe Label System.

  • BCMA Technology: Characterization of Med Triggers and Workarounds (Article)

    There’s an interesting article in the February 2011 issue of The Annals of Pharmacotherapy dealing with BCMA and what the author describes as “clinical workarounds”.1

    Abstract

    BACKGROUND: Bar code medication administration (BCMA) technology is gaining acceptance for its ability to prevent medication administration errors. However, studies suggest that improper use of BCMA technology can yield unsatisfactory error prevention and introduction of new potential medication errors.
    OBJECTIVE: To evaluate the incidence of high-alert medication BCMA triggers and alert types and discuss the type of nursing and pharmacy workarounds occurring with the use of BCMA technology and the electronic medication administration record (eMAR).
    METHODS: Medication scanning and override reports from January 1, 2008, through November 30, 2008, for all adult medical/surgical units were retrospectively evaluated for high-alert medication system triggers, alert types, and override reason documentation. An observational study of nursing workarounds on an adult medicine step-down unit was performed and an analysis of potential pharmacy workarounds affecting BCMA and the eMAR was also conducted.
    RESULTS: Seventeen percent of scanned medications triggered an error alert of which 55% were for high-alert medications. Insulin aspart, NPH insulin, hydromorphone, potassium chloride, and morphine were the top 5 high-alert medications that generated alert messages. Clinician override reasons for alerts were documented in only 23% of administrations. Observational studies assessing for nursing workarounds revealed a median of 3 clinician workarounds per administration. Specific nursing workarounds included a failure to scan medications/patient armband and scanning the bar code once the dosage has been removed from the unit-dose packaging. Analysis of pharmacy order entry process workarounds revealed the potential for missed doses, duplicate doses, and doses being scheduled at the wrong time.
    CONCLUSIONS: BCMA has the potential to prevent high-alert medication errors by alerting clinicians through alert messages. Nursing and pharmacy workarounds can limit the recognition of optimal safety outcomes and therefore workflow processes must be continually analyzed and restructured to yield the intended full benefits of BCMA technology.

    The study described in the article utilized a combination of retrospective analysis and direct observation to identify alert triggers generated by a BCMA system. In addition the study looked at various workarounds utilized by nursing as well as pharmacy. The article is a much more limited version of the one by Koppel in 2008.2

    The Annals article identifies some disturbing trends at the Medical University of South Carolina (MUSC) where the study took place. Examples include failure to document override reasons for 77% of alert messages and 468 directly observed workarounds during 121 administration attempts over a 6 hours period. Those number are a sure sign of a poorly designed system and lack of institutional oversight. It certainly has nothing to do with BCMA and the overall effectiveness of the technology. Sounds like some disciplinary action is in order.

    One other thing I found unusual in the article was the classification of pharmacy workarounds. “Specific pharmacy workarounds included duplicate orders, lack of medication order verification, medications within the incorrect section of the eMAR (prn vs standard administration time), and incorrectly timed medications causing administration too late/early for the nursing staff.” I’m not sure how you see this, but a duplicate order isn’t a workaround, it’s an order entry error. Same goes for entering an order as PRN instead of SCH. Not sure what the author had in mind when he made the decision to classify these as workarounds. Weird.

  • Cool Technology for Pharmacy – Sharp SX Bagger

    Some items in a pharmacy are simply difficult to bar-code. Perhaps they’re too small, have an awkward shape or their surface won’t accommodate ink or an adhesive. The problem creates some interesting workarounds, and not always for the better.

    One solution is to individually package each item and place the drug information and a bar-code on the outside of the packaging material; overwrapping, if you will. I’ve never been a big fan of overwrapping items because it can be time consuming and cumbersome. Today I ran across a machine that I think offers a genuine option for medications that are difficult to bar-code.

  • The National Drug Code (NDC) is a gremlin in the works of pharmacy

    The National Drug Code, or NDC number as it’s affectionately called in pharmacy, is a set of numbers used to uniquely identify “human drugs and biologicals“. Every pharmacist is familiar with the NDC number, but if you’re not it’s basically a  unique number assigned to each package of medication. It’s an 11 digit number in a 3-segment format, i.e. XXXXX-XXXX-XX.

    The first segment consists of five digits and indicates the manufacturer of the drug. The second segment is four digits used to identify the medication and strength. And the final segment of two digits represents the package size.
