PACE Trial: Chronic Fatigue Syndrome/Myalgic Encephalomyelitis

Lord Wallace of Saltaire Excerpts

Wednesday 6th February 2013 Grand Committee

[Lord Layard]

My Lords, I too greatly welcome this debate. This is a terrible condition and we are talking about hundreds of thousands of people who are suffering from it. While it is clear that although there have been many studies relative to the seriousness and pervasiveness of this condition, there is far too little research into what is causing it. I want to focus on treatment, as there have been terrible misunderstandings and misconceptions put about on that score.

I want to make just four points. First, the issue of what causes the condition is often quite different from how we can best treat it. This is such a basic point but it is not fully understood by many of the people suffering from this condition. Coronary heart disease may be caused by cholesterol but we treat it with a stent. In the same way, chronic fatigue may be caused by a virus yet the best treatment available at the moment may include psychological therapy. This form of treatment implies nothing about what we believe to be the cause. People who suffer from CFS, and who in almost all cases feel that it is not psychological in origin, are surely making a mistake when they reject psychological support for their condition on the grounds that this implies something about its cause. In their own interest, they should focus on what is the best possible treatment available on the evidence.

Secondly, we have quite a lot of evidence about which treatments work. More will surely be discovered in future and some of them will surely be biological. In the mean time, we have a large amount of evidence that both CBT and graded exercise therapy enable many more people to recover than if the only treatment they have is standard medical care. My main point here is that this is so, whatever the definition of recovery. It is wrong to suggest that this all depends upon that definition; you can put the cut-off for recovery in many different places and you will always find that people who get CBT and graded exercise therapy do better than people who have only standard medical care. There are many studies preceding PACE to show this. Of course, that is the main finding of PACE, which I would say is a fine piece of work by all normal standards. Some of the criticisms are really misleading but some of them have been answered already.

I come back to this question of the change in the protocol to stress that this was made before any analysis was done of the results. It was not that they looked at the results and said, “Let’s change the recovery criteria”. The changes were made because of discussions affecting the whole research world and agreed by the trial steering committee. What is very interesting is that a separate paper has been written simply on the recovery issue, which uses five or six different criteria of recovery. Again, in the PACE study it is shown that whatever cut-off you use, you get the same difference between the outcome of CBT and graded exercise therapy. There really is not a conjuring trick going on here and it is wrong for this impression to be given to the community of people who are suffering, if that leads to them not receiving help which they could really benefit from. Instead of criticising the study, we should be rejoicing that we again have more evidence that something can be done which is better than standard medical care.

My third point has, in a way, been made before but given the strength of this evidence that we have these treatments which work, it is shocking that they are so little available. This is part of a wider story of the non-availability of psychological therapy. The survey that was done by Action for M.E. found that a large number of PCTs were providing no specialist treatment clinics for this condition—or were not providing any kind of care, let alone this most evidence-based care. That is a disgrace and I hope that the Minister can say something about that.

The treatments are not unsafe, a claim that is often put about due to the fact that, of course, some people get worse during treatment. The only argument against the treatment, if it were the case, would be if people who did not receive it were less likely to get worse. Again, the statistics are absolutely clear: the proportion of people who get worse in treatment is no higher than that for people who get worse who are not in treatment. There is no argument whatever that this is unsafe.

My fourth point is about how we can get a better deal for this large group of sufferers. Obviously, the worst possible way to get it is to turn the area into a battleground. It gives the commissioners the perfect excuse for doing nothing and gives people of good will, who might come in and try to help people with this condition, a serious disincentive for getting into this field. As we know, and has already been said, many—or certainly some—of the people who work in this area have received repeated insults and even death threats. I pay particular tribute to Sir Simon Wessely at King’s College London, who has led the field for many years in this area and has stuck to it, despite all this harassment. He and his colleagues—

My Lords, the noble Lord is in his seventh minute. We are very tight on time and I am worried that the Minister will not have time to reply.

[Lord Layard]

I will stop at this point.
