Four Corners Big Vitamins exposé: cuts both ways

Vitamins, by Steven Depolo

Last night’s Four Corners exposé of Big Vitamins marketing their supplementary pills via community pharmacists would have had doctors throughout the nation nodding their heads.

We only have to walk past a pharmacy shopfront to see how rife the problem is. Clearly most pharmacist-owners see it as a profitable—some would argue, a critical—part of their business plan.

As for pharmacist-employees, most are presumably resigned to selling these supplements by the kilo, and some would perhaps believe the industry’s own hype that ‘pick me up’ vitamins really do pick people up. Even well people, with clean livers.

The issue is not so much the selling of products in a free market, but the dubious veneer of scientific credibility, beginning with exaggerated or false advertising claims and ending with a highly trained, trusted professional. As a pharmacist said on the show, “If they’re after complementary medicines, then I’m happy to provide them”.

After such media reports featuring sceptical doctors, inevitably some commenters retort by questioning why they pick on pharmacists, when the medical profession itself is so influenced by Big Pharma. Something about sinners casting the first stone.

And, you know what? They have a point. So, let’s lob a few stones in every direction, even if a wall of my own glass house cracks. Continue reading

Five reasons why I’d still encourage my child to do medicine

Back Camera

If you read the wrong kind of comments in the online medical media – as I do, religiously – you might conclude that retiring doctors are glad to be leaving the sinking ship. These disembarking medicos  proclaim they would discourage their child from ever boarding the leaky vessel. Why commit to years of study, long hours, frustrating paperwork, little respect and crappy pay?

After all, being a doctor is a tough gig these days. Especially if you stretch ‘these days’ to include one million days ago. Hippocrates noted in his opening line of the first ever book about the burden of being a doctor, “Life is short, and art long, opportunity fleeting, experimentations perilous, and judgement difficult”.

Life is less short since Hippocrates’ day, but the rest still rings true. Today’s graduates will face increasing bureaucracy and regulation. Recent reports highlight the threats of bullying from within the profession and of litigation from without—although I’d argue neither is escalating.

Would I encourage my child to do medicine? You bet I would, and here are five reasons why. Continue reading

GP Sceptics podcast 8: Marketing

‘Carrots & Sticks’ by Kat Ritchie

itunes-logo     soundcloud

Doctors try to ‘sell’ behaviour change to patients, who are often reluctant to ‘buy’ the message. What tricks can we learn from the modern experts at selling?

Justin and Liz bite the bitter bullet and enter the strange world of marketing.

We grill Dr Ninya Maubach, whose former life involved a PhD in marketing, but who has now seen the light and is studying medicine at ANU. That’s a powerful combo when it comes to teaching doctors how to sell a message.

Our starting point is a paper ‘Carrots, Sticks and Promises’, and it turns out that most of our attempts at behaviour change involve the least effective selling method: “I promise that if you stop this pleasurable thing today (e.g. smoking, lying on your couch), you will reap rewards in the future.”

That message is pretty easy to trump (are we still allowed to use that word?), and plenty of full-time tobacco and food industry marketers know just how to trump it.

Turns out the ‘stages of change’ model  we all learned (precontemplation, contemplation)may not be so useful after all. Continue reading

Google Health Cards: the first test drive

google-health-cards

Google’s new health cards became active in Australia just a few hours ago, so I figured I’d be first to give them a test run.

Health cards are Google’s attempt to give the lay public sensible and evidence-based results on searches for medical conditions.

The ‘cards’ appear as a stand-alone box to the right of the usual Google search results, and contain a few sentences and a picture.

For example, when I type in ‘cold’, the usual, familiar results appear – first is my local weather (despite today being decidedly warm!) followed by the hits from more than a billion search results.

But in addition, a new box automatically appears, labelled ‘Common cold’. It contains an artist’s impression of nose-blowing (happily, a ‘before’ image with the tissue still clean) and three clickable sections: About; Symptoms; and Treatments.

Each section typically contains a couple of brief statements and some dot points. The health information is general, but accurate, having been developed in conjunction with doctors from the Mayo clinic. No unpleasant surprises suggesting your cold might require antibiotics. Continue reading

Just when you thought GP Sceptics put the E in evidence-based medicine, we pull the rug from underneath your trusting feet.

Western Australian GP Casey Parker, of Broome Docs fame, joins our twosome to become the ‘third nerd’ – a role which fits him like a cardigan and a new pair of glasses.

Casey delves into EBM’s dark recesses, where p-hackers subvert the concept of ‘significance’, and RCTs answer all the questions no one bothered asking.

Justin discusses a hot-off-the-press systematic review revealing the over-optimism of doctors.

And Liz? Liz invites us all aboard the EBM gravy train.

Bonus nerd points for any listener who comments below correctly describing when affect is a noun and effect is a verb.

This podcast is dedicated to the fond memory of the late Prof Gavin Mooney, editor of Evidence-based medicine in its place.

Thanks to Dr Kat Ritchie for her brilliant artwork.

Does the weather affect our joints?

midsummer

Therefore the moon, the governess of floods,
Pale in her anger, washes all the air,
That rheumatic diseases do abound.

A Midsummer Night’s Dream

Long before Shakespeare, vagaries in the weather have been blamed for flare-ups of joint pain. The rheumatic curse seems to redouble on a cold, wet day…or is it a hot, dry one?

But a new study from The George Institute casts doubt that we can ever really “blame it on the weather”.

In every place I have ever worked, patients will swear their knee or back pain has eased since they moved to that town, crediting their temporary cure to the local conditions. Curiously, this remains true regardless of where I am working at the time, whether at the bottom or the top of Australia: from the windswept southern coast to the burning central deserts or humid tropics.

Are rainfall, humidity and temperature really affecting my patient’s joints, or is there a less exciting interpretation? Perhaps joint pain is a randomly relapsing condition, and we humans love attributing causation whenever two unrelated events roughly coincide.

Previously, researchers at the George Institute published a study where 345 Australians with confirmed knee osteoarthritis recorded their pain scores. No correlation whatsoever was found between pain flares and the local weather conditions (temperature, precipitation, humidity, barometric pressure).

This negative study, which countered such a long-held belief, not surprisingly copped plenty on social media. Contrarian anecdotes flew in faster than a cold southerly over Bass Strait.

So other researchers decided to see if they could replicate the findings in different circumstances. Continue reading

Liz shines when discussing her pet PhD topic – managing obesity in general practice. Nicely timed for Christmas.

Which medications safely make us thinner, now amphetamines and tobacco have lost favour? And, if media images keep depicting Headless Fatties*, how can GPs raise the topic without adding to the stigma?

Justin reveals that one of Australia’s biggest GP education companies is boasting it can change our prescribing habits at will – for a hefty fee.

Build your own promotional campaign with Liz’s Magic Marketing, and discover the superpower Justin wishes he possessed but his family knows he doesn’t. gp_sceptics_small

Anne Deveson, who destigmatised schizophrenia

anne_deveson_2013

THE DEATH of Anne Deveson –writer, broadcaster and social justice advocate – marks the final chapter of a life that reflected the immense change in the way Australians have perceived mental health issues over the past century.

Deveson, who died from Alzheimer’s yesterday at age 86, recalled travelling home from London 40 years ago after her father referred to her mother’s bewildering mental decline in a letter. “Bea is bats,” wrote her father, unable to articulate the subtleties of what we now know was Alzheimer’s disease.

Upon Deveson’s return, her mother described the affliction more poetically: “Anne, I’ve been in a forest and I can’t find my way through.”

If Australians’ understanding of mental illness has altered dramatically since the Deveson family arrived from Malaya as refugees during World War II, their famous daughter could claim much responsibility. Continue reading

Why ‘medicine for the rich’ is sometimes inevitable

stockmarket

The issue: Poor people can’t afford high-cost drugs privately

Player #1: The Australian PBS, which has just released this year’s list of top 10 pharmaceuticals by expense (see table below)

Player #2: The Social Medwork, a new company which imports high-end drugs, for a fee

My verdict: Sorry, that’s life. The public can’t afford to pay for everything.

THE DILEMMA posed by high-cost pharmaceuticals isn’t one likely to go away any time soon.

With hepatitis C treatments clocking up their first $1 billion in just four months, PBS budgeters must be sweating.

However, they would also be relieved that they didn’t cave in to the campaign – backed by the manufacturer but involving patient advocacy groups and some doctors – to approve the drugs earlier at an even higher cost, as happened in the US.

Coming second on the PBS expense list, at half a billion, are two macular degeneration drugs with their own cost controversies.

The manufacturer of ranibizumab (Lucentis) has been heavily criticised for purchasing the patent on its only competitor but not doing the head-to-head study that might have allowed approval for the cheaper drug. Back then, Lucentis cost 50 times the price of its competitor, and it remains the gift that keeps on giving, near the very top of this year’s PBS spending. Merry Christmas, shareholders.

At the top end of the market, where high-rollers spend public funds on the promise of clinical benefit, it is no surprise that a new player has entered the room. A Netherlands-based company has just created a new niche for those customers who can afford it. Continue reading

GP Sceptics podcast 5: Lyme disease…don’t get sold a lemon

tick

Ten thousand miles away…Australia’s closest lyme-carrying tick

itunes-logo   soundcloud

To coincide with today’s Senate inquiry on how to catch Lyme Disease in Australia (short version – you can’t), Justin and Liz interview infectious disease expert Prof Frank Bowden, from Australian National University.

Frank swats aside a series of claims by Australian lyme disease proponents, but sounds stumped when Justin asks whether sentinel chickens or sentinel ticks are better at keeping watch.

The conversation takes a few twists, lurching from false positive US lab results to unrelated matters such as whether having sex before the game enhances or detracts from sports performance. You’ll have to listen to find out the answer.*
