Drug information questions for PSL-2 in Prezi

I have finally found a good use for Prezi, a zoom presentation tool that I have posted about previously.  For the second year pharmacy student drug information lecture I created a Prezi around a drug information question.  This allowed non-linear paths through the information (cf with Powerpoint slides).  The class dictated which information to reveal next, they could not be influenced by "the instructors next slide is ____, therefore this must be the next step".  It worked quite well, and I think I will be using Prezi again.

Are clonazepam wafers available?

Is azithromycin safe in pregnancy?

Is there a drug interaction between risperidone and simvastatin?

Systematic Approach to Drug Information - BC DPIC

In a previous post I uploaded my Principles of Drug Information lecture for 1st year pharmacy students at the University of Manitoba.  This year, as I am preparing for the 2nd and 3rd year lectures, I came across this four part video on YouTube from BC DPIC (Drug and Poison Information Centre, Vancouver, BC).

After a quick scan, the content of these videos seems to be very similar to the lecture that I gave.  It is good to know that DI centres seem to be on the same page.  Wouldn't it be nice if everyone shared presentations like this. It doesn't make sense that there are multiple DI pharmacists creating essentially the same presentation from scratch!  Thank you DPIC.

Pill Identification for Canadian pills

What is the best way to identify a stray pill?

Except for the round, white, unmarked tablets; color, shape, score lines and imprint codes can assist with identification.

There are many pill identification tools online and I have been asked several times for my professional opinion on the usefulness of one or more of these programs for the identification of pills from Canada. Many of these databases are of US origin and their accuracy in identifying Canadian pills is unknown.

For a more objective comparison I decided to search for 3 different Canadian pills using 9 different ID tools available online. From my past experiences, one is more likely to identify the correct pill when searching via imprint codes alone. Addition of color and shape often leave you with no results and descriptions of color and shape are not standardized. For example the same pill could be described as oval, capsule shaped, or caplet; or a peach toned pill could be labelled as orange or pink. Also imprints codes are almost guaranteed to be unique to the product, where as there are limited colors and shapes for any pill.

I used an imprint code search for the following Canadian pills:

• Co ciprofloxacin 500 mg tablet, made by Cobalt Pharmaceuticals, a generic manufacturer in both the US and Canada.
• Description in the eCPS: Each white to off-white, capsule shaped, biconvex, film-coated tablet, embossed “CR 500” on one side and (embossed arrowhead or greater than sign) on the other side.
• I searched for CR 500 (symbols can not be used in these databases)
• Comment: It appears that this pill has the same markings in Canada and the US, therefore I would expect to find it in almost all of the databases.

• Hyzaar 50 mg/12.5 mg (losartan 50 mg & hydrochlorothizaide 12.5 mg). Made by Merck Frost, a large brand name manufacturer in the US and Canada.
• Description in the eCPS: Each yellow, oval shaped, film-coated tablet, marked with code 717 on one side and plain on the other.
• I searched for 717.
• Comment: In November 2008 Merck Frosst changed the tablet shape and imprint codes in Canada, but not the US, therefore I would expect that the US based databases will only find the US product.



• Novamoxin 500 mg capsules, made by NovoPharm, a large generic manufacturer in Canada only.
• Description in the eCPS: Each hard gelatin capsule with opaque scarlet cap and yellow body, size #0, printed white NOVO and 500 on opposing cap and body portions of the capsule.
• I searched for Novo 500.
• Comment: NovoPharm products are not available in the US, therefore I would not expect to find this drug in the US databases.

Pill identification databases searched:

FREE DATABASES:

• Pillbox beta enables identification of solid dosage forms based on imprint, shape, color, size and scoring. It is currently under development by the National Library of Medicine and National Institute of Health and is not intended for clinical use (then why is it freely available online??). As of September 2009 is contains 5,693 records, but only 779 have images. Additional drug information is provided by DailyMed and the Drug Information Portal. This database is US based. I used the HMTL-based screen reader compatible version as my office computer did not allow use of the Adobe Flex version.
• DailyMed Product Identification System is also provide by the National Library of Medicine and contains 5128 approved prescription drugs in the US. One can search via imprint, color, shape, size and scoring. Additional drug information is provided from the official FDA labels
• Drugs.com Pill Identifier content is provided by Cerner Multum and Thomson-Reuter Micromedex. This website has a disclaimer that it is intended for use by consumers in the United States only. One can search for pills via imprint (mandatory), color and shape (both optional). Provides links to addition drug information from Physicians' Desk Reference, Cerner Multum, Micromedex and Wolter Kluwer Health. US based database.
• RxList.com Pill Identification Tool is another US based database that allows consumers to search for pills via imprint, color, shape, and brand/generic name. RxList is owned and operated by WebMD. I could not find what sources of drug information are used for this database.

SUBSCRIPTION DATABASES: (requires paid subscription for access)

• Micromedex Identidex is produced by Thomson Reuters. Users can search via imprint code, color, shape or pattern. It contains more than 74,000 indexed terms to identify pharmaceuticals based on imprint codes. Micromedex Identidex is US based, but they attempt to include international products as well. Links to additional drug information (DrugDex monograph or PoisonDex, if user has subscription to these databases).
• Facts & Comparisons 4.0 Drug Identifier is produced by Wolter Kluwer and contains more than 5,000 images. Users can search via imprint, dose form, score, shape, color 1, color 2, trade/generic name, labeler/manufacturer name, or NDC/labeler code. Once a product is found links to Drug Facts and Comparisons monograph and MedFacts/Medguide patient handouts are available. All Facts & Comparisons products are US based.
• eCPS Product Identification Tool is the only exclusively Canadian identification tool that I am aware of. Product information and images are provided by the manufacturer. One can search via dosage form, shape, color, imprint, scored, brand name or generic name. There are no links to complete product monographs, users must return to the eCPS general search for additional information. This tool only contains brand name products, therefore it will not be able to identify generic pills. It also contains images of injections, transdermal patches, topical products, powders, inhalers, eye/ear product, suppositories, etc.
• eCPS Advanced Search is not specifically designed as a product identification tool, but can be used as such, if one searches for imprint codes in the product information section of the monographs. This advanced search will search all monographs in the eCPS, including generic products and is a useful compliment to the Product Identification Tool.
• Lexi-Drug ID provided by Lexi-Comp searches for pills based on imprint, dosage form, shape or colors. Links are provided to search other Lexi-Comp databases for additional drug information once product has been identified. It is a US based tool.

RESULTS: Documented whether each site found the correct drug, if the manufacturer was identified and if an image of the pill was available for verification.

Results are in Google Docs spreadsheet (as I could not figure out how to insert my original Word table here!)

No single pill identification database found all three pills via imprint codes. Micromedex Identidex and the eCPS Advanced Search identified 2 out of the 3 pills. The eCPS Product Identification Tool was the only database that provided an image to confirm the identity of a pill (Hyzaar). The free US based databases did not find any of the Canadian pills.

Several databases identified Co ciprofloxacin 500 mg because the US and Canadian products have the exact same imprint codes, but this would not necessarily be known to the searcher and not all manufacturers use the same imprint codes for US and Canadian products.

Hyzaar 50 mg/12.5 mg was only identified by the eCPS, all of the other databases found the US product which is also imprinted with 717, but after the November 2008 manufacturing change, this would not be helpful for identifying the Canadian product. Searching only for 717 resulted in numerous results on several of the websites, in this case narrowing by color or shape would have helped to decreased the number of results.

Novamoxin, the exclusively Canadian product was only identified by Micromedex. The eCPS Product Identification Tool only includes brand name products, and the Advanced Search function found 500+ results when searching for Novo 500. No results were found the other databases.

LIMITATIONS: Results only apply to identification of Canadian pills, as the majority of the databases were US in origin, one would expect better results when attempting to identify US pills. Databases were selected based on familiarity and accesibility, therefore other important pill identification databases may have been excluded. The three pills were selected with the knowledge that many of the databases were US based, this may have biased the results against the US databases. Use of the subscription databases are restricted to paid users, which limits their usefulness for those who do not have access.

DISCUSSION: There are a couple other methods for identification of Canadian pills. The easiest method is to ask a dispensing pharmacist or technician who see these products on a daily basis, in many cases they can identify the pill with a quick glance.

Most Canadian provinces attempt to control drug costs by using generic products, therefore many requests for pill identification will be from a Canadian generic manufacturer. Companies like Apotex, NovoPharm, Pharmascience, GenPharm (now Mylan), and Cobalt use distinct and easily recognized imprint codes (Apotex =APO; Novopharm = NOVO, Pharmascience = P or PMS, etc). Each of these companies websites maintain a product directory with product images, therefore once the pill manufacutrer is identified, the website can used for confirmation. These sites do not allow imprint code searching, therefore probably would not be useful to the non-pharmacist, but this is the method that I use to identify generic products in Canada.

Other Canadian databases that are not useful for identification of pills from imprint codes, shape or color include the Drug Product Database (DPD) from Health Canada. This website allows searching via DIN (Drug Identification Number), ATC (Anatomical Therapeutic Classification), Company, Product Name (brand), Active Ingredient (generic), and Active Ingredient Group Number). Some of the entries have links to the complete Canadian product monograph, therefore DPD could be used for confirmation after a pill is identified, but at the moment is not useful for inital searching. This database probably has the most potential for development into a pill ID tool.

Medbroadcast.com for Canadian consumers is produced by MediResource provides Canadian drug information, but is only searchable via DIN or drug name.

Ident-a-drug from Therapeutic Research Center (publishers of Pharmacists' Letter and Natural Medicines Comprehensive Database, two of my favorites) allows searching via imprint code, US NDC or Canadian DIN or advanced searching. This is a subscription database that I do not have access to, therefore I could not include it, but it appears promising.

CONCLUSION: The best pill identification websites for identification of Canadian pills via imprint codes are the eCPS (Product Identification Tool and Advanced Search) and Micromedex Identidex. As expected the US based databases failed to identify Canadian products, except when the imprint codes were exactly the same in both countries (Co ciprofloxacin). Even then, confirmation with a Canadian resource is require to confirm this, as some pills have different imprint codes in the US and Canada (Hyzaar). Pills from exclusively Canadian manufacturers (Novamoxin) will not be found in US databases.

There is a need for a comprehensive Canadian pill identification tool as reliance on US based databases is inappropriate and inadequate. Pharmacists currently must work with several sources (eCPS, Micromedex, generic manufacturer websites) when attempting to identify pills via imprint codes and there are no freely available pill ID sites for Canadian consumers. In my opinion organizations such as Health Canada or the Canadian Pharmacists Association (publisher of the CPS) are in the best position to develop such a tool.

Things are different

Winnipeg sunset, Sept 22/09

The world (wide web) is different.....

I had no internet connection this morning at work for several hours, interfered with my ability to answer questions, in the past I used to joke that I was "going old school" and using real books and journal to answer question, now, because of the amount of information available via the internet, and the importance of this information, I can not do my job to the best of my abilities if I do not have an internet connection. At this point I probably could survive without the library of books in my office! One of these days I'm going to have to act on my threat to move drug information to a beach on Hawaii, and see how long I can go until they realized I'm not at my desk in the hospital.

My (small) world is different......

Once I got my internet connection back, I quickly logged into Google Reader to see what I had missed in the morning and came across this article Am J Health Syst Pharm. 2009 Oct 1;66(19):1718-22. Update on the status of 89 drug information centers in the United States.

The last sentence of the conclusion confirms my experiences over the past several years, "The most notable changes in these DICs (drug information centres) were increases in the number of DICs focusing on educating health-professions students, the complexity of drug information questions, and the amount of time required to answer each request.

There are likely many factors influencing these changes, but I think that the abundance of easily accessible medical information is an important one. Rather eliminating the need for drug information pharmacists, it has amplified it. The clinical pharmacist on the ward responsible for 40 sick patients does not have the time or expertise to find answers to all the questions they need answered in a day. A drug information pharmacist functions as a consultant for these questions, and are able to search the for the most relevant information, and use their training as a pharmacist to come up with an answer for that specific situation or patient.

The number of drug information centers focusing on education of students is also not surprising, faculties are trying to prepare students for this information abundant environment and who better to teach it then a pharmacist who does this as a career (though the as the best "do-ers" are not necessarily the best teachers).

All of this turned into conversations with my coworkers about the internet, about information, etc. I realized that I am different, my view and perspectives are changing from strictly a "pharmacist's view point" to a pharmacist with a unique perspective on the role of technology in this environment. Now I just have to figure out what I am going to do with this unique perspective....

Connectivism and Connective Knowledge Course

Course number three for me in the certificate for emerging technologies for learning is CCK09. I'm glad that it is the third course, as I have had time to learn about and use many different tools which will allow me to focus on more on course content. I've added a folder to my Google Reader for CCK09 feeds (Google alerts, blogs, twitter, The Daily, course website, etc). I already use my reader on a daily basis to keep up with work related feeds, so this is a great place for me to put CCK09 info as well.

Before I signed up for this course I read some of the post from last years participants and found that there was a common theme of feeling overwhelmed and not being able to keep up with everything that was going on. So my plan is to be selective. Though, I'm not sure how I'm going to do that intelligently, how can I choose the best info when I haven't viewed it all! Of course I have this problem at work as well, how can I provide an evidence based answer to a drug related question if I haven't review all of the evidence. In this environment I can go to systematic reviews, meta-analyses, clinical practice guidelines, and experts to filter the important information. I will have to find out what filters are useful in this environment.

I would not consider myself an "educator", but when you think about it, a major component of a health care professionals job is to educate (patients, the public, students, other professionals), so I'm sure that I will take away something useful from this course.

I have never studied learning theories, so week 1 has been a lot of reading and listening and browsing. Next I need to work on connecting and participating. I can now empathize with pharmacy students I teach, asking someone to participate when the information is completely new and foreign can be very intimidating. I need to remember this when I am in my comfortable drug information pharmacy world.

CMAP for Digital Literacy Course

Here is my concept map for the Digital Literacy course in PDF and website format. I deliberately started with my original definition of literacy from the Introduction to Emerging Technology course and built up from there, adding information literacy, then digital literacy. Digital literacy is at the top because is encompasses everything below it.

Concept Map for Introduction to Emerging Technology course

One of the final assignment for the Introduction to Emerging Technology course was creation of a concept map, bringing together all the ideas and linking them in way that makes sense to the student. This is my personal concept map of the course, I started by mapping the major themes that were covered each week, then started to link them together. As you can see it turned into a fairly complex and organic map, which offended my modular and linear brain, but straight lines did not appropriately convey the associations.

Note: The link to PDF may take a few seconds to load and you may need to zoom in to read all the details.
