Information to Pharmacists

Editorial

From the desk of the editor

Welcome to the July 2014 homepage edition of i2P (Information to Pharmacists) E-Magazine.
At the commencement of 2014 i2P focused on the need for the entire profession of pharmacy and its associated industry supports to undergo a renewal and regeneration.
We are now half-way through this year and it is quite apparent that pharmacy leaders do not yet have a cohesive and clear sense of direction.
Maybe the new initiative by Woolworths to deliver clinical service through young pharmacists and nurses may sharpen their focus.
If not, community pharmacy can look forward to losing a substantial and profitable market share of the clinical services market.
Who would you blame when that happens?
But I have to admit there is some effort, even though the results are but meagre.
In this edition of i2P we focus on the need for research about community pharmacy, the lack of activity from practicing pharmacists and when some research is delivered, a disconnect appears in its interpretation and implementation.

Feature Contribution

Woolworths Pharmacy - Getting One Stage Closer

Neil Johnston

It started with “tablet” computers deployed on shelves inside the retailer Coles, specifically to provide information to consumers relating to pain management and the sale of strong analgesics.
This development was reported in i2P under the title Coles Pharmacy Expansion and the Arid PGA Landscape”
In that article we reported that qualified information was a missing link that had come out of Coles market research as the reason to why it had not succeeded in dominating the pain market.
Of course, Woolworths was working on the same problem at the same time and had come up with a better solution - real people with good information.

Intensive Exposition without crossing over with a supermarket

Fiona Sartoretto Verna AIAPP

Editor's Note: The understanding of a pharmacy's presentation through the research that goes into the design of fixtures and fittings that highlight displays, is a never-ending component of pharmacy marketing.
Over the past decade, Australian pharmacy shop presentations have fallen behind in standards of excellence.
It does not take rocket science - you just have to open your eyes.
Recently, our two major supermarkets, Woolworths and Coles, have entered into the field of drug and condition information provision - right into the heartland of Australian Pharmacy.

The sure way to drive business away

Gerald Quigley

I attended the Pregnancy, Baby and Children’s Expo in Brisbane recently.
What an eye and ear opening event that was!
Young Mums, mature Mums, partners of all ages, grandparents and friends……...many asking about health issues and seeking reassurances that they were doing the right thing.

‘Marketing Based Medicine’ – how bad is it?

Baz Bardoe

It should be the scandal of the century.
It potentially affects the health of almost everyone.
Healthcare providers and consumers alike should be up in arms. But apart from coverage in a few credible news sources the problem of ‘Marketing Based Medicine,’ as psychiatrist Dr Peter Parry terms it, hasn’t as yet generated the kind of universal outrage one might expect.

Community Pharmacy Research - Are You Involved?

Mark Coleman

Government funding is always scarce and restricted.
If you are ever going to be a recipient of government funds you will need to fortify any application with evidence.
From a government perspective, this minimises risk.
I must admit that while I see evidence of research projects being managed by the PGA, I rarely see community pharmacists individually and actively engaged in the type of research that would further their own aims and objectives (and survival).

Organisational Amnesia and the Lack of a Curator Inhibits Cultural Progress

Neil Johnston

Most of us leave a tremendous impact on pharmacies we work for (as proprietors, managers, contractors or employees)—in ways we’re not even aware of.
But organisational memories are often all too short, and without a central way to record that impact and capture the knowledge and individual contributions, they become lost to time.
It is ironic that technology has provided us with phenomenal tools for communication and connection, but much of it has also sped up our work lives and made knowledge and memory at work much more ephemeral.

Academics on the payroll: the advertising you don't see

Staff Writer

This article was first published in The Conversation and was written by Wendy Lipworth, University of Sydney and Ian Kerridge, University of Sydney
In the endless drive to get people’s attention, advertising is going ‘native’, creeping in to places formerly reserved for editorial content. In this Native Advertising series we find out what it looks like, if readers can tell the difference, and more importantly, whether they care.
i2P has republished the article as it supports our own independent and ongoing investigations on how drug companies are involved in marketing-based medicine rather than evidence-based medicine.

I’ve been thinking about admitting wrong.

Mark Neuenschwander

Editor's Note: This is an early article by Mark Neuenschwander we have republished after the soul-searching surrounding a recent Australian dispensing error involving methotrexate.
Hmm. There’s more than one way you could take that, huh? Like Someday when I get around to it (I’m not sure) I may admit that I was wrong about something. Actually, I’ve been thinking about the concept of admitting wrong. So don’t get your hopes up. No juicy confessions this month except that I wish it were easier for me to admit when I have been wrong or made a mistake.
Brian Goldman, an ER physician from Toronto, is host of the award-winning White Coat, Black Art on CBC Radio and slated to deliver the keynote at The unSUMMIT for Bedside Barcoding in Anaheim this May. His TED lecture, entitled, “Doctors make mistakes. Can we talk about it?” had already been viewed by 386,072 others before I watched it last week.

Dispensing errors – a ripple effect of damage

Kay Dunkley - BPharm, Grad Dip Hosp Pharm, Grad Dip Health Admin, MPS, MSHPA

Most readers will be aware of recent publicity relating to dispensing errors and in particular to deaths caused by methotrexate being incorrectly packed in dose administration aids.
The Pharmacy Board of Australia (PBA), in its Communique of 13 June 2014, described a methotrexate packing error leading to the death of a patient and noted “extra vigilance is required to be exercised by pharmacists with these drugs”.
This same case was reported by A Current Affair (ACA) in its program on Friday 20 June

Take a vacation from your vocation

Harvey Mackay

Have you ever had one of those days when all you could think was, “Gosh, do I need a vacation.”
Of course you have – because all work and no play aren’t good for anyone.
A vacation doesn’t have to be two weeks on a tropical island, or even a long weekend at the beach. 
A vacation just means taking a break from your everyday activities. 
A change of pace. 
It doesn’t matter where.
Everyone needs a vacation to rejuvenate mentally and physically. 
But did you also know that you can help boost our economy by taking some days off? 
Call it your personal stimulus package.

Explainer: what is peer review?

Staff Writer

This article was first published in the Conversation. It caught our eye because "peer review" it is one of the standards for evidence-based medicines that has also been corrupted by global pharma.
The article is republished by i2P as part of its ongoing investigation into scientific fraud and was writtenby Andre Spicer, City University London and Thomas Roulet, University of Oxford
We’ve all heard the phrase “peer review” as giving credence to research and scholarly papers, but what does it actually mean?
How does it work?
Peer review is one of the gold standards of science. It’s a process where scientists (“peers”) evaluate the quality of other scientists' work. By doing this, they aim to ensure the work is rigorous, coherent, uses past research and adds to what we already knew.
Most scientific journals, conferences and grant applications have some sort of peer review system. In most cases it is “double blind” peer review. This means evaluators do not know the author(s), and the author(s) do not know the identity of the evaluators.
The intention behind this system is to ensure evaluation is not biased.
The more prestigious the journal, conference, or grant, the more demanding will be the review process, and the more likely the rejection. This prestige is why these papers tend to be more read and more cited.

Dentists from the dark side?

Loretta Marron OAM BSc

While dining out with an elderly friend, I noticed that he kept his false tooth plate in his shirt pocket. He had recently had seven amalgam-filled teeth removed, because he believed that their toxins were making him sick; but his new plate was uncomfortable. He had been treated by an 'holistic dentist'. Claiming to offer a "safe and healthier alternative" to conventional dentistry, are they committed to our overall health and wellbeing or are they promoting unjustified fear, unnecessarily extracting teeth and wasting our money?

Planning for Profit in 2015 – Your key to Business Success

Chris Foster

We are now entering a new financial year and it’s a great time to reflect on last year and highlight those things that went well and those that may have impacted negatively in the pursuit of your goals.
It's also a great to spend some time re-evaluating your personal and business short, medium and long term goals in the light of events over the last year.
The achievement of your goals will in many cases be dependent on setting and aspiring to specific financial targets. It's important that recognise that many of your personal goals will require you to generate sufficient business profits to fund those aspirations

Attracting and Retaining Great People

Barry Urquhart

Welcome to the new financial year in Australia.
For many in business the past year has been described as a challenging period.
Adjectives are a key feature of the English language.  In the business lexicon their use can be, and often is evocative and stimulate creative images.  But they can also contribute to inexact, emotional perceptions.
Throughout the financial pages of newspapers and business magazines adjectives abound.
References to “hot” money draw attention and comment.  The recent wave of funds from Chinese investors, keen to remove their wealth from the jurisdiction and control of government regulations is creating a potential property bubble in Australia.

Updating Your Values - Extending Your Culture

Neil Johnston

Pharmacy culture is dormant.
Being comprised of values, unless each value is continually addressed, updated or deleted, entire organisations can stagnate (or entire professions such as the pharmacy profession).
Good values offer a strong sense of security, knowing that if you operate within the boundaries of your values, you will succeed in your endeavours.

Evidence-based medicine is broken. Why we need data and technology to fix it

Staff Writer

The following article is reprinted from The Conversation and forms up part of our library collection on evidence-based medicines.
At i2P we also believe that the current model of evidence is so fractured it will never be able to be repaired.
All that can happen is that health professionals should independently test and verify through their own investigations what evidence exists to prescribe a medicine of any potency.
Health professionals that have patients (such as pharmacists) are ideally placed to observe and record the efficacy for medicines.
All else should confine their criticisms to their evidence of the actual evidence published.
If there are holes in it then share that evidence with the rest of the world.
Otherwise, do not be in such a hurry to criticise professions that have good experience and judgement to make a good choice on behalf of their patients, simply because good evidence has not caught up with reality.

Laropiprant is the Bad One; Niacin is/was/will always be the Good One

Staff Writer

Orthomolecular Medicine News Service, July 25, 2014
Laropiprant is the Bad One; Niacin is/was/will always be the Good One
by W. Todd Penberthy, PhD

(OMNS July 25, 2014) Niacin has been used for over 60 years in tens of thousands of patients with tremendously favorable therapeutic benefit (Carlson 2005).
In the first-person NY Times best seller, "8 Weeks to a Cure for Cholesterol," the author describes his journey from being a walking heart attack time bomb to a becoming a healthy individual.
He hails high-dose niacin as the one treatment that did more to correct his poor lipid profile than any other (Kowalski 2001).

Culture Drive & Pharmacy Renewal

Neil Johnston

Deep within all of us we have a core set of values and beliefs that create the standards of behaviour that we align with when we set a particular direction in life.
Directions may change many times over a lifetime, but with life experiences and maturity values may increase in number or gain greater depth.
All of this is embraced under one word – “culture”.
When a business is born it will only develop if it has a sound culture, and the values that comprise that culture are initially inherent in the business founder.
A sound business culture equates to a successful business and that success is often expressed in the term “goodwill” which can be eventually translated to a dollar value.

Generation and Application of Community Pharmacy Research

Neil Johnston

Editor’s Note: We have had a number of articles in this issue relating to pharmacy research.
The PGA has conducted a number of research initiatives over the years, including one recently reported in Pharmacy News that resulted from an analysis of the QCPP Patient Questionnaire.
Pharmacy Guild president, George Tambassis, appears to have authored the article following, and there also appears to be a disconnect between the survey report and its target audience illustrated by one of the respondent comments published.
I have asked Mark Coleman to follow through, elaborate and comment:

Methadone induced long QTc and "torsade de pointe". Bittar P, Piguet V, Kondo-Oestreicher J et al. Swiss Medical Forum 2002 S4;P

Dr Andrew Byrne & Associates

articles by this author...

A Harm-Minimisation Research Perspective: Dr Byrne (and his associates) advocate for better policies which are proven to reduce risks for drug users and the general community, under a framework in parallel with Australia’s official policy of harm minimisation.

Dear Colleagues,

This instructive case history which pre-dates Krantz’s report by several months, describes a long term methadone patient aged 39 developing ‘torsade de pointes’ a few days after starting triple therapy for HIV in the context of opioid withdrawal symptoms/signs and low blood levels. The patient also had chronic hepatitis C and epilepsy. As well as valproic acid for the latter, benzodiazepines, cannabis and alcohol were also involved in this seminal case.

The patient presented to the emergency room in opioid withdrawal. There was no electrolyte disturbance but methadone level was found to be ‘sub-therapeutic’ despite daily doses of 115mg administered by suppository (this is routinely used by some doctors in Switzerland). The QTc interval was available from a month before the episode at 480ms (n < 450ms). That cardiograph may have been ordered as part of a ‘work-up’ prior to starting anti-retroviral therapy but this is not detailed in the text.

While in hospital, 15 minutes following the daily rectal methadone dose the patient developed bradycardia, bigeminy and then torsade tachycardia. He was successfully resuscitated despite major seizures occurring simultaneously. The methadone was replaced by morphine 200mg twice daily which was associated with QTc interval reduction from 480 to 430ms.

Subsequent challenge a few days later with just 40mg methadone saw the QTc interval increase to 520ms and so the trial was abandoned due to the perceived risk. A cardiograph two weeks later showed the QTc interval to be still slightly elevated at 460ms despite the methadone having been long ceased. These observations are consistent with other evidence that methadone causes some modest prolongation of the QT interval and that this effect alone is generally of little clinical significance.

This patient took methadone, valproic acid, alcohol, cocaine and cannabis for at least 7 years without reported cardiac problems and so the onset of torsade during a period when the methadone level was low is hard to ascribe as a direct and dose-related effect. Rather, a combination of factors including possibly some myocardial ‘priming’ may be occurring.

This appears to be the very first of over 100 case reports in the literature of torsade de pointes in patients taking methadone maintenance for addiction. In nearly every case where details are available there were other drugs, extremely high dose, overdose, HIV and/or electrolyte disturbance reported. Pearson has called this a ‘threshold’ effect. Since methadone levels are sometimes in the low range it is possible that the drug is sometimes a ‘bystander’ while other drugs and/or the HIV virus itself might be responsible for the electrical instability in the heart.

Like others, these authors give some details of the management given to the patient. Even 7 years later, there still appears to be little agreement about an approach to treatment as cardiologists, intensivists and emergency physicians describe quite diverse approaches. These have included (1) efforts to maintain heart rate, (2) restoring electrolyte balance, (3) removal of triggering factors and (4) supportive measures. Magnesium and potassium infusions, administration of isoprenaline, atenalol, quinidine, lignocaine, amiodarone (!), glucoheptonate; implantable cardioverter-defibrillator (ICD); reducing methadone; continuing methadone; changing to morphine or buprenorphine. A review of such clinical manoeuvres by a cardiologist would be highly desirable in my view.

Instead of this logical step, Krantz and his panel have advised ‘discussions of risk’ (which are still largely unknown), pre-treatment ECG and continued QT interval monitoring. This is in the context of a lack of evidence for the effectiveness of such a strategy to prevent arrhythmias. Krantz’s group, in their extensive literature review of almost 100 papers left out numerous seemingly relevant articles (eg. Justo, Athanasos, Krook and Cruciani). It is hard to understand how the CSAT panel of experts could have completely overlooked these crucial papers, each of which is available on a simple internet search.

Further, despite the clear association with HIV infection (40% according to Justo), HIV is not even mentioned in the entire Annals paper from March 2009. The drugs gabapentin and ciprofloxacin come up in numerous reports, including 5 of Krantz’s original series of 9 pain management cases. Likewise, the issue of targeting strategies to those taking such medication is not emphasised by the CSAT panel report.

This early report from Switzerland contains some vital but conflicting evidence concerning causation. Like others, these authors find evidence of multifactorial causes for their patient’s torsade tachycardia. Yet there seems to be QT prolongation in relation to methadone dose levels, despite torsade occurring only very rarely in such cases. The cautious trial to reintroduce methadone caused QT prolongation but no arrhythmia. At the same time, it is questionable that a purported side effect of methadone would occur when the blood level was low and the patient was in a drug-induced withdrawal state.
