Masterpiece: GS1 Tag Data Standard 1.5
GS1 EPCglobal ratified and published the most recent version of the Tag Data Standard (TDS), 1.5. I have always been a fan of TDS, but earlier versions served as much to expose embarassing disconnects in GS1 standards as they did to explain how to apply GS1 identifiers in an Radio Frequency IDentification (RFID) context. Earlier versions of TDS tightly bound the concept of the Electronic Product Code (EPC) to RFID, and that’s just wrong. “EPC”, even as defined in those earlier versions of TDS, is a way of uniquely identifying objects on a global basis. It’s purely a globally unique identifier standard. That’s a hugely important and relatively new concept. RFID–a simple data carrier technology that’s been around for many years–is almost insignificant in comparison.
Even the name “Tag Data Standard” reflects this wrong-headed binding of EPC to RFID by seeming to place the RFID “Tag” at the center of the “standard”. Yes, there is a need for a “Tag Data Standard”, to show how to encode an EPC into an RFID tag, but it is wrong to Read the rest of this entry »
Yifan “Ivan” Shen (1962–2010)
I received news last night that my friend and co-worker, Ivan Shen, passed away on Sunday after losing a five month battle with cancer. During his career Ivan worked for serialization and pedigree companies including Oat Systems, Reva Systems and SupplyScape (now TraceLink). Many RxTrace subscribers are current or former co-workers or former customers of Ivan. Read the rest of this entry »
Estimated Rise In Serialized Drugs In The U.S. Supply Chain
Back in 2005 I created a line graph of my personal prediction of the percentage of pharmaceuticals in the U.S. supply chain that would be unit-level serialized by the manufacturer and I circulated it among my co-workers at the time. I based it purely on guesses that were “supported”–very flimsily–by the number of large pharmaceutical manufacturers who were participating in the GS1 EPCglobal Healthcare and Life Sciences (HLS) Business Action Group (BAG) (the group is now defunct), and the existence of an early version of the California Pedigree Law. The graph included a high and low line that formed a band that I thought would be where the reality would fall. In that prediction I didn’t think most manufacturers would achieve 100% serialization of their products until sometime between 2010 (high) and 2015 (low).
In my analysis at that time, I theorized that the actual percentage would start out following my “low” estimate line, but at some unpredictable point, something would happen that would cause the percentage to jump up to the “high” estimate line. At the time, I assumed the event that would cause that jump would be the U.S. Federal government issuing some kind of pedigree regulation that included a unit-level serialization requirement.
As it turned out, things moved slower than I had guessed. Here it is 2010 and the percentage of drugs in the supply chain with unit-level serial numbers on them is so small that it’s tough to give it a percentage. But I think my estimate from way back in 2005 was not bad for its time (but notice I’m not publishing the actual graph). After all, the California Pedigree deadline has been pushed out at least three times since then (from 2007 to 2009, to 2011, to 2015/1016).
I think the future is a little less murky now because, since 2005, Read the rest of this entry »
RxTrace, One Year Retrospective
RxTrace is now one year old. There are 34 essays that together amount to a true liberal exploration of the intersection between the pharmaceutical supply chain, track and trace technology, standards and regulatory compliance…as promised.
My personal favorite essays from the past year, in chronological sequence are:
- The Florida Pedigree Law (August 10, 2009)
- The California Pedigree Law (September 7, 2009)
- What Are Pedigree Laws Trying To Accomplish Anyway? (November 2, 2009)
- Who owns supply chain visibility data? (December 31, 2009)
- The Deputized Supply Chain (January 31, 2010)
- FDA Aligns with GS1 SGTIN For SNDC (March 29, 2010)
- RFID is DEAD…at Unit-Level in Pharma (April 12, 2010)
- The Modern Pharmaceutical Wholesaler and the Approaching Transformation (May 7, 2010)
- California Pedigree Law: Historic Change to Commerce (June 14, 2010)
Since late January I have been collecting some statistics on page views on RxTrace and here is the list of the essays in the sequence of page views since that time. Read the rest of this entry »
The “Normal Distribution” Concept
Understanding the concept of “Normal Distribution” is important in understanding the status of pedigree regulations in the United States pharmaceutical supply chain. The term itself didn’t exist back in the late 1980′s when the federal Prescription Drug Marketing Act (PDMA) pedigree provisions were originally enacted by Congress but the concept is built into that law as the “Authorized Distributor of Record” (ADR) concept. When states began enacting their own pedigree legislation back in the early 2000′s, the term “normal distribution channel” was defined to describe the path of drugs when they move through the most common–or “normal”–sequence of supply chain owners. It’s a concept that is explicitly defined in most state pedigree legislation.
When a pedigree law is a “normal distribution” law, it generally means that pedigrees are not needed for any shipment or change of ownership where the drugs do not leave this common/typical/normal path as defined in the law. But as soon as a change of ownership or custody occurs where the drug leaves this “normal” path, a pedigree is then necessary.
Typically, when a pedigree is required outside the “normal distribution channel”, that pedigree must Read the rest of this entry »
California Pedigree Law: Historic Change to Commerce
“…[C]ommencing on July 1, 2016, a wholesaler or repackager may not sell, trade, or transfer a [prescription] drug at wholesale without providing a pedigree.
…[C]ommencing on July 1, 2016, a wholesaler or repackager may not acquire a [prescription] drug without receiving a pedigree.
…[C]ommencing on July 1, 2017, a pharmacy may not sell, trade, or transfer a [prescription] drug at wholesale without providing a pedigree.
…[C]ommencing on July 1, 2017, a pharmacy may not acquire a [prescription] drug without receiving a pedigree.”
With these words the State of California introduced a significant change to the way the pharmaceutical supply chain works (see section 4163 of the California Business and Professions Code) and has written a new page in the history of commerce. It brings pharmaceutical commerce fully into the computer age. Adam Smith would not recognize it. Today, and up to the effective dates of these provisions, the value of a legitimate pharmaceutical in the legitimate U.S. supply chain is determined by the physical condition of the product and its package. After July 1, 2016, the value of a legitimate pharmaceutical in the supply chain in California will be determined by the combination of the physical condition of the product and its package, and the sellers ability to provide the buyer with an electronic pedigree.
The intended effect of this new regulatory requirement is to place a significant roadblock in front of counterfeiters, diverters and others who would try to scam patients and the legitimate participants in the supply chain. This is a noble cause. By requiring sellers to provide buyers with a pedigree at each change in ownership in the supply chain, illegitimate parties will find it very hard to inject illegitimate drugs without exposing their actions and, at the same time, creating evidence that can be used against them in their own prosecution. By providing a pedigree at each change in ownership, supply chain buyers will be able to check the authenticity of the full supply chain transaction history provided by the seller, maximizing the likelihood that any suspicious activity would be detected long before a patient would receive the drugs.
But I’m more interested today in exploring a surprising unintended effect of these requirements. I’ve touched on this briefly in past essays but I’ve recently concluded that the implications of these requirements are much more significant than I realized before. This may be the first time in the history of commerce that Read the rest of this entry »
