Health: Medical Innovation

Lord Winston Excerpts

Wednesday 16th January 2013 Lords Chamber

[Lord Winston]

My Lords, it is both a responsibility and a privilege to be the first speaker after the deeply moving speech from the noble Lord, Lord Saatchi. He carries the respect of the whole House for tabling this debate and has our thanks for the way that he phrased what he said. I feel that my own contribution will be paltry by comparison, but I thought that it would be interesting to look quickly at my own career and think of seven points in it where innovation was an issue. Our excellent Minister sitting on the Front Bench cannot be expected to be responsible for trying to improve innovation in the health service. This is a colossally difficult issue; I will explain why I think so.

The first thing I want to refer to briefly is my involvement in the early days of microsurgery of the fallopian tube. First, that project, which led to about 50 publications, would not have been possible today because the Medical Research Council grant that I got would not be awarded with the current competition. Secondly, it is fair to say that I would not have got an animal licence to practise a surgical procedure, rather than to do it experimentally. There is a neat difference now in how the regulation is. Throughout, there are at least eight issues that conflict to make innovation difficult. One is regulation; one is infrastructure; one is governance; one is industry and its involvement; one is the internal market, supported by both the Labour Party and the Conservative Party; one is clinical training; another is teamwork. Lastly and most importantly, there is the cultural environment. I will come to one other issue at the end, if I may.

The infrastructure for my work with the fallopian tube would not be possible now because I had access then to a workshop in a district general hospital, where Dennis Melrose was producing extracorporeal circulation pumps to improve heart surgery. That is almost unthinkable now. One of the greatest difficulties I had was in getting industrial support for making the microsurgical needles. I could not find a single industry in this country that would make the needles. We made needles with our own hands, under a microscope, that were so fine and delicate that they did not fall to the ground. Unlike the noble Lord’s papers, they actually floated on the air. Eventually, we found a German company which then captured one-third of the world’s ophthalmic market with those needles. There is a message in that innovation.

With regard to trying to translate that surgery into the female pelvis, the big problem now would be governance. What also followed was the issue of having training in teamwork around, to persuade surgeons to work as a team. That has become more difficult now because of the internal market. It is very difficult to prove that a surgical procedure works and is innovative, because it is more difficult to collect the cases together within a health service structure. We have all faced this difficulty for quite a long time. It is not the responsibility of any one Government.

The same thing applies, to some extent, to laparoscopic surgery. I think I was one of the first people to operate using a laparoscope in this country. There would now be a problem with governance; it would be considered risky and unwise, and would take much longer to innovate.

With the present regulatory system, it would also be impossible to see in vitro fertilisation—your Lordships probably know that I have certainly more than dabbled in that—on the books in the way that it is now. It would be very difficult to transfer an egg that you fertilise outside the body into a human patient. It would certainly take much longer to get permission to do that. That is one of the issues. In my own unit, we made a whole series of improvements. We improved the culture media. We demonstrated, for example, the given knowledge that glucose in the medium was poisonous to human embryos but not to any other animal that was experimented on. We could not change those media now, given the current regulatory framework. Even the little changes that one could make—the fact that tungsten light is dangerous to embryos, for example—become increasingly difficult.

I could go on and on but I do not want to spend more than a few minutes and my time is almost up. It would now take much longer to get permission for things such as embryonic detection of genetic defects. I have to declare an interest as somebody who launched a biotech company. One of the problems with that company, which might change the whole field of transplantation with the use of pigs’ kidneys, hearts and livers, and possibly pigs’ lungs, is that it took us more than a year and a quarter to get an animal licence to practise and do the work on just six pigs. It was quite difficult to get the rodent licence before that as well.

I want to say one final thing. The first experiment I ever did was as a result of fraud in my unit. I was asked to go in and troubleshoot by repeating an experiment. It was pure serendipity that we found that there was probably something wrong, with an infection in the vagina of women that might lead to the possibility of a virus being involved. We now know, of course, that the virus is very well established but I did not know what it was at the time. That was a long time ago but one of the issues with true innovation is that serendipity is extremely important. What we can perhaps best all do together is to see how we might improve the culture in which we do our medicine.
