The Light Fantastic?

January 20th, 2009 by hope

According to The Times, Sir Terry Pratchett is trying out an antidementia helmet:

The author Sir Terry Pratchett is testing an antidementia helmet, which it is claimed can slow down or even reverse Alzheimer?™s disease. The helmet, invented by Gordon Dougal, a GP, directs intense bursts of light at a patient?™s skull.

While I can’t be certain this is complete quackery, it does appear to be suffering from a lack of evidence and has the whiff of too good to be true. I am surprised and can’t help thinking he’d be better sticking with his nice black hat.

“No one knew better than Granny Weatherwax that hats were important. They weren’t just clothing, hats defined the head. They defined who you *were*. No one had ever heard of a wizard without a pointy hat?” at least, no wizard worth speaking of. And you certainly never heard of a witch without one… Hats had power. Hats were important.”

Terry Pratchett, Witches Abroad.

Strictly General Practice

January 6th, 2009 by hope

In the recent series of Strictly Come Dancing, the retired political correspondent John Sergeant performed spectacularly well. The judges had mistaken the show for a talent contest, rather than the test of popularity. Sergeant consistently hammered the better dancers in the contest in terms of the public vote, despite lacking any apparent dancing skills beyond dragging a bedazzled lady across the floor. However, John Sergeant’s dance skills were strictly irrelevant, the problem was the nature of the competition.

In much the same way, the government are now proposing a Strictly General Practice competition:

Patients in England will be able to comment on their GP’s performance on an NHS website, under government plans.
[...]
Mr Bradshaw told the Guardian: “I would never think of going on holiday without cross-referencing at least two guide books and using Trip Adviser.

“We need to do something similar for the modern generation in healthcare.

“I can already learn a lot from the comments of people, both positive and negative, about a type of treatment or a hospital. We need to extend the service to cover GPs.”

Oh dear. It appears that Ben Bradshaw has fallen for the fallacy that a Web 2.0 commenting system that people use to rate DVDs, computer games, or Hotels is automatically a good thing to assess professional skills. The customer is always right, or always knows what they prefer, may be useful in the purely commercial sector, but in a professional environment there are problems in its application.

The professional may make decisions in the best interests of their client, which the client may not consider to be in their best interests. For example, a patient may have an expectation of a prescription medicine to be given following a consultation with a GP, when the GP knows that the antibiotic may not be required (therefore carrying avoidable risks to the patient) or add to the burden of antibiotic resistance in the population.

A more important issue with such rating systems is that professionals have professional expertise that patients are unable to assess due to their own lack of knowledge. This may be seen as a paternalistic viewpoint by some, but people do go to the doctor for expertise they do not themselves hold. What are anecdotal comments from patients really going to tell you about a doctor’s diagnostic skills, or pharmacological knowledge?

In July of this year I wrote about a similar non-governmental attempt to rate general practitioners, and pointed out a comment about a particular GP. I repeat the comment again:

He was held in very high regard by the overwhelming majority of his patients. He was also respected by fellow professionals. His patients appear to have regarded him as the best doctor in Hyde. His register was full and there always seems to have been a waiting list. Patients liked him for a variety of reasons. Many would say that he ‘always had time’ for them. His surgeries overran but no one minded because they understood his wish to take whatever time was necessary for each patient. He never hurried them out. He always had time for a few words of a personal nature. Elderly patients and their families were particularly grateful for his willingness to visit at home.

That comment is about Harold Shipman, the most efficient serial killer in British history. Thankfully, he will be unable to benefit from the new government scheme, but I doubt he would have come off badly in such a scheme.

Janet Daley at The Daily Telegraph notes the BMA’s opposition to the scheme, and states that:

This is precisely the kind of comparison measure that tends to raise the standards of a public service in which there is no market mechanism to give consumers power of purchase.

No it isn’t. Any patient who uses such a scheme to judge their GP’s abilities would be making a grave mistake, akin to judging the abilities of the pilot on a plane by the sound of his voice when making turbulence announcements, or assuming John Sergeant was a good dance partner based on the public vote in Strictly Come Dancing.

The religious anti-vaccine circle

January 6th, 2009 by hope

As well as damaging education, including throwing acid at schoolgirls, the Taliban are repeating the claim of Nigerian religious leaders that Polio vaccine is designed to reduce fertility.

The militants [Taliban] have also prohibited immunisation for children against polio – claiming that the UN-sponsored vaccination drive is aimed at causing sexual impotence – causing a sharp rise in cases of the disease.

Such concerns about “population control” or genocides by vaccine are widespread on the internet. UNICEF and WHO are argued to be in on a conspiracy to control population growth that is suggested to be the idea of the New World Order, the Illuminati, or a typical anti-semitic Jewish conspiracy. Extremists of all stripes promulgate these conspiracy theories, including far right US groups. Their websites are read by other extremists. Here is the leader of the Muslim Brotherhood in Sudan in summer 2007.

Interviewer: You issued a fatwa prohibiting the vaccination of children, claiming it is a conspiracy of the Jews and Freemasons. Is this true?

Al-Majid: This is 100% true.
[...]
Interviewer: But from where did you get the information about a conspiracy?

Al-Majid: I am following this issue, along with two or three brothers. We are following this issue globally through the Internet, through several media outlets, and through the ministry that carries out this procedure, which I consider to be a crime against the children.

Of course, we have similar problems in the UK, of an admittedly less extreme nature, also couched in terms of “safety”.
