Health and Social Care Bill

Debate between Lord Hunt of Kings Heath and Earl Baldwin of Bewdley

Monday 5th December 2011 Lords Chamber

[Lord Hunt of Kings Heath]

My Lords, we come to a no less interesting subject than the issue of fluoridation of the water supply, which I know will be of interest to many noble Lords. I ought to start by declaring an interest as president of the British Fluoridation Society and, as someone convinced by the benefits of fluoridation, I want to ensure that those benefits continue in the future.

In 1964, Birmingham became the first UK city to introduce a water fluoridation scheme. By 1970, six years after its introduction, the number of teeth affected by decay in five year-olds had dropped by 46 per cent in a part of Birmingham, Northfield, as compared to those in Dudley, which fell by only 2 per cent. A report by the regional director of public health in 2006 found that children in fluoridated areas of the West Midlands with relatively high levels of social deprivation often had better dental health than children in relatively affluent areas where water supplies were not fluoridated. I am keen that progress continues to be made and that more areas are fluoridated in the future. The question before us is whether the arrangements in the Bill actually help or hinder that.

Under the new arrangements, it will be for a local authority, or local authorities, to make a proposal on fluoridation to the Secretary of State. If the Secretary of State agrees that such a proposal should be supported, the proposer must notify all other local authorities affected by the proposal and make arrangements as to how they should proceed. Regulations are apparently to be made on how local authorities might come to a consensus view.

An important question arises as to payment. The current 1999 Act provides a mechanism under which authorities can be made to bear the full cost of fluoridation. The Secretary of State can require the local authorities affected by arrangements made by the Secretary of State for the fluoridation of water with the water undertaker to meet the Secretary of State’s cost incurred under the terms of the arrangement. In the new situation that we have, I am concerned that the whole process of approval and funding of such schemes seems to be rather convoluted. I hope that the noble Baroness may be able to reassure me on this point.

The first key question is: will there be sufficient resources to meet the cost of existing or future fluoridation schemes? Local authorities do not, of course, provide dental services and they do not have dental service budgets to call upon; yet clearly the impact of fluoridation is to reduce tooth decay. If less money is spent on treating tooth decay, that money should be able to become available for other aspects of dental and oral health care. If local authorities do not have a direct interest in the cost of dental health care, will that be an impediment to the expenditure of money on fluoridation schemes? Again, it would be very helpful if the Minister could inform me as to her view on that as well.

At this stage, this is essentially a probing amendment to ensure that the Government are as committed to fluoridation schemes as I believe they ought to be. I see that the noble Earl, Lord Baldwin, is in his place. From my point of view, the evidence is convincing. It is important that if local authorities come to a view that they wish to fluoridate or to continue to fluoridate, the money will still flow as smoothly as the fluoride in the water in places that are lucky enough to benefit from water fluoridation schemes. I hope that the Minister can assure me.

[Earl Baldwin of Bewdley]

My Lords, I support what the Government are doing here, though with some reluctance, for reasons that will not surprise the noble Lord, Lord Hunt. I am reluctant for two reasons that lie at the heart of a fluoridation policy: the scientific evidence for it and the medical ethics. It will pay to revisit those briefly this evening.

It is now 15 years since I started putting down Questions to the Government, chiefly on the evidence surrounding fluoridation. In the late 1990s the previous Government conceded that the studies they relied on were old and not of very good quality. Sir Iain Chalmers, a leading healthcare scientist who was then director of the UK Cochrane Centre, joined me in pressing for a high-quality systematic review. The Government agreed. That review, which came to be known as the York review, was conducted by the NHS Centre for Reviews and Dissemination at the University of York. I served on its advisory board as it examined 50 years of the world literature. The results, published in 2000, surprised many people.

Not one good-quality study could be found. This meant that nothing could be stated with clear confidence: not efficacy in preventing caries—though that did appear likely—not safety, and significantly not the hoped-for evidence that fluoridation might even out the inequalities in dental health between social groups. So poor was the evidence for that question that the four senior research scientists who were involved in the review described it in a letter to Health Ministers at the time as “weak, contradictory and unreliable”.

I know from the previous amendment that it is dangerous to quote the noble Earl, but I was interested to reread the speech of the noble Earl, Lord Howe, on the regulations of the Water Act in 2005, and to read that he, too, was impressed by the lack of good evidence as shown by York. I emphasise that the York review was not just any old review—there have been plenty of those. This was a Rolls-Royce systematic review, conducted to the highest international standards, the only one of its kind in the field. A more recent Australian systematic review has been unable to find anything that would change York’s conclusions.

I wish I could say that this better understanding of the evidence had influenced policy. Having accepted York’s findings, through gritted teeth, governments have downplayed them and, at times, subverted them. For the past 10 years the York scientists, when they had the time to do so, and I have been trying to point people back to what the known evidence shows. In the face of deeply held beliefs, this has been quite an uphill task.

The question of ethics, which is my second objection, can be put in a nutshell. In our society, a person faced with a healthcare intervention is free to accept or reject it. This is the principle of individual informed consent. We find it in case law and in pronouncements from all kinds of medical bodies. Fluoridation is invasive and unavoidable. Therefore fluoride designed to protect teeth should not be delivered by this method. I could say much more, as indeed I have many times in your Lordships’ House, but now is not the time or the place. These twin objections, evidence and ethics, are what motivate most of the large number of people who oppose community water fluoridation.

Given, however, that such schemes exist, and that the Government are determined to provide for new schemes, how best should they be structured? I believe that what the Government are proposing here is a significant improvement on what went before. The old system where water companies had a veto over new schemes was clearly not ideal. Since the Water Act 2003, strategic health authorities have been in the driving seat. Curiously enough, the All-Party Group against Fluoridation that I subsequently chaired was given an assurance by Health Ministers in the previous Government that they would put elected local authorities in charge, as is now proposed. However, when it came to their Water Act, it did not happen.

The problem with the unelected SHAs was—is—that they almost inevitably reflected the dominant medical view. Fluoridation was a classic case of premature consensus, on weak evidence from the 1950s and 1960s, and it became a kind of sacred cow, resistant to new evidence, as I have indicated with the York review. The regional director of public health who advised the SHA that recently decided to fluoridate Southampton, against the expressed wishes of its population, described fluoridation correctly as the “professional orthodoxy”. Sir Iain Chalmers, who knows more about medical evidence than most people, has described it publicly as a “religion”.

A most unfortunate feature in all this is that so many prominent bodies should have signed up with the National Alliance for Equity in Dental Health as campaigners for fluoridation—not just supporters, campaigners. The website of the British Fluoridation Society shows the British Dental Association, the British Medical Association, the Faculty of Public Health Medicine, the NHS Confederation, the UK Public Health Association, among dozens of other such bodies, including some royal colleges and about 60 primary care trusts. If you have signed up to a campaign, not only are you compromised in terms of impartial advice but it is very hard to draw back. It is much easier to keep going forward with your professional peer group. And, if you are the people whose advice is being sought and heeded, there is likely to be only one outcome.

While fluoridation continues, these clauses may offer the least worst way forward. In parenthesis, referendums would show more clearly what local people want. There have been quite a number in America, but as they have tended to reject fluoridation the Government may be wary of them. Even here, to have your healthcare treatment decided by a majority vote of your neighbours is not a principle known to medical ethics. At least local authorities are accountable to the populations they serve and, while quite properly taking advice from all quarters, should be better able to gauge than the SHAs have been what is right for their communities. People should not have to accept what Big Brother, or rather Big Doctor, thinks is good for them. I broadly support these clauses, but the devil will be in the regulations.

I conclude by putting three questions to the Minister. First, will she consider providing for a neutral body to set out the current state of the evidence in any future public consultation? This was suggested by Iain Chalmers back in 2003. Some of the misstatements during the Southampton consultation were pretty terrible. Secondly, will she include in that a revision of the Chief Dental Officer’s guidance letter of February 2008 to decision-makers over fluoridation? I think that the noble Earl, Lord Howe, suggested to me that this would happen. Thirdly, will she give the undertaking, given by the previous Government during the passage of the 2003 Act and the regulations in 2005, that no new scheme will go ahead unless the local population is in favour? If so, will she ensure that any undertaking given—the noble Lord, Lord Warner, who is not in his place, was one who gave it at the time—will not be watered down in the regulations so as to lose its effect, as happened last time?
