1 Licensing
1.1 The National Rules Scheme
This allows homeopathic products to bear
therapeutic indications, and is not based on any evidence at all. The MHRA
consultation which preceded the new legislation, MLX312, openly admitted that
"homeopathic products have difficulty in demonstrating efficacy in clinical
trials". As the MHRA rightly insists on clinical trial evidence for orthodox
drugs, this was the clearest admission that the MHRA knew homeopathic products
to be ineffective. One reason that the MHRA gave for forcing though the rules
was that to do nothing would have inhibited the expansion of the homeopathic
industry. It is not at all clear as to why this was important to the MHRA, or
why it was in the public interest to be offered an increasing number of
ineffective products - and to be lied to about their lack of effect. However
the MHRA is not funded by taxation but by fees, and it is certain that not
issuing new licences would have cut off an income stream.
1.2 Double Standards
The MHRA's report on the MLX312
consultation minimised opposition and emphasised support from industry. Yet the
new legislation does not comply with classical homeopathic teaching, which is
that treatment must be individualised. The labelling regulations cater for
pre-packaged products available in retailers such as (and especially) Boots,
which are of course not individualised. There can be absolutely no possibility
of the careful recording of history and symptoms which are the homeopath's stock
in trade. Yet the homeopathy companies supported the regulations
enthusiastically. This shows the level of duplicity endemic in the practice of
homeopathy.
Curiously, the first product to receive a
licence under the new rules was homeopathic arnica, which has most recently
been tested in clinical trials and found to be ineffective. Also, it violates
the `like cures like' principle of homeopathy, so makes no sense even under the
bizarre requirements of the new rules.
2 Funding
2.1 Cash Costs
I have submitted a separate report on
primary care trust funding trends. There are however other costs of homeopathy.
For example, central government paid some £20 million for the refurbishment of
the Royal London Homeopathic Hospital. The business case for this project said
nothing at all about the clinical outcomes that would result from this
expenditure.
2.2 Potential Cost Savings
The actual amount of money spent on
homeopathy is a small part of the NHS budget. But it has the effect of
undermining the effort to make evidence based practice (EBP) the norm. Critics
of orthodox medicine state that a large proportion of it is not evidence based.
This is not true to the extent claimed, but apart from falling victim to the tu
quoque fallacy, it misses the point. The NHS could make very large savings
by progressing more rapidly towards full EBP. There would be no better
demonstration of such a commitment than to close its homeopathic hospitals as
soon as possible.
Yet it is astonishing to see that the NHS
seems determined to repudiate EBP. It has just been announced that the pilot
patient budgets scheme will allow the money to be spent on complementary
medicine, including homeopathy. If the idea of this scheme was to put patients
in control of their health, what message does this transmit? Here was an
opportunity to educate patients about cost-effectiveness, but instead they are
put in charge of wasting public money. Patients will therefore demand the right
to spend their budgets on whatever they like. There is a virtually endless choice
of medical fads and fashions to feed that demand.
3 Evidence
3.1 The Quality of Evidence
It is important to focus on the best
quality evidence. Randomised controlled trials (RCTs) provide the most rigorous
test of a therapeutic claim. Homeopaths either denigrate RCTs as inappropriate
for their speciality, or select poor quality RCTs that spuriously show positive
results. They also cite uncontrolled observational studies which are no more
than customer satisfaction surveys. It is true that a broad and inclusive
approach needs to be taken to clinical evidence. Thus pragmatic trials and
observational studies are part of the mix. But it is a serious mistake to rely
on these and to dismiss RCTs. Evidence based medicine is one of the greatest
achievements of science. It has the RCT at its core. RCT evidence has
overturned many accepted practices, often by showing them to be harmful, and
commonly by showing them to be ineffective.
3.2 Spurious Evidence
Homeopaths claim that substances diluted
beyond Avogadro 's number have specific therapeutic effects. RCTs, especially
when assembled into meta-analyses and systematic reviews, clearly show that
this is not true. Some homeopaths argue that specific and non-specific effects
cannot be separated (as do some sociologists). These arguments try to recruit
support from unrelated fields such as quantum mechanics. For example, long
papers have been written on 'patient-practitioner entanglement'. No
experimental or observational evidence has been offered to support these ideas.
They are no more than a smokescreen to hide the fact that specific effects of
homeopathic dilutions do not exist.
3.3 The Ethical Dilemma
There is a serious ethical problem if
treatments that are effectively placebos are to be offered to patients. Doctors
are required by the terms of their registration to give treatments that they
reasonably expect to be effective. By any scientific test, homeopathic products
are ineffective, placing them outside EBP. Also, doctors have to obtain
informed consent for treatment. Therefore to prescribe homeopathy doctors must
inform patients that they are giving them a placebo. They must convey to
patients what the scientific evidence is. This is a principle that is extremely
poorly enforced by the GMC and the medical Royal Colleges. The various
professional bodies for homeopaths ignore EBP altogether, as does the voluntary
regulation scheme launched by the Complementary and Natural Healthcare Council.
This is dishonest, and demeaning for patients. If patient choice is to mean
anything, it must be informed choice.

Declaration of Interests
I am a freelance clinical science
consultant with over 30 years of experience in clinical research. I do
voluntary work for two charities, Sense About Science and HealthWatch, in
support of evidence based medicine. I do not receive any payments, in cash or
in kind, for these activities. Most of my professional clients are
pharmaceutical companies, but they have no connections with this voluntary
work.
