My Lords, I wish to concur with some of the points made; I do not speak against anything said by the noble Baroness, Lady Finlay. We are in complete agreement and I do not counteract anything that she says anyway. Having said that, most people look at medicines as things that cure disease. Most medicines do not cure disease. Symptoms are what patients experience, and we have to treat those symptoms. As an obstetrician, I have spent most of my life treating the symptoms of pain, prescribing morphine and heroin as painkillers to mothers who are suffering from labour pains. I could not measure their pain in any way except by what they told me about it.
The problem with database evaluation is that it looks for the size of the randomised trials. I suggest that observational studies that look at the experience of patients are a good enough database to evaluate whether the substance used is effective in alleviating their suffering. That is the sort of evidence that I hope NIHR will seek to establish a proper database. I am pleased to hear the Minister say that NIHR is looking at ways of dealing with this.
