Selective Dorsal Rhizotomy

Debate between Tom Brake and Paul Burstow

Wednesday 18th April 2012 Commons Chamber

[The Minister of State, Department of Health (Paul Burstow)]

I congratulate my hon. Friend the Member for Daventry (Chris Heaton-Harris) on securing the debate and bringing this very important matter to the attention of the House. The contributions of other hon. Members demonstrated just how strongly people feel about the issue. He outlined with great clarity the huge impact on the lives of children and of their families. Such debates are often prompted by casework but, interestingly and quite rightly, they can be prompted by the diligent work of local journalists reporting in the local press, which is testament to the importance of our local papers.

As my hon. Friend is aware, cerebral palsy is a brain condition that affects movement, posture and co-ordination. It might be seen at or around the time of birth or might not become obvious until early childhood. Some children will have lower limb spasticity, which can cause problems with walking and sitting, as well as discomfort, cramps and spasms. Sadly, there is no cure for cerebral palsy and as no two children are exactly the same, which means that they will not be affected by cerebral palsy in exactly the same way, treatment programmes vary widely.

Occupational therapy, speech therapy, medication and surgery all have a role to play in reducing the impact of the condition, but, because all children with cerebral palsy have movement problems, physiotherapy, to which the hon. Member for Strangford (Jim Shannon) referred, is undoubtedly the bedrock of the condition’s good management.

NHS physiotherapy services, including post-surgery physiotherapy for children with cerebral palsy, are provided on the basis of assessed clinical need, but initiatives such as the self-referral-to-physiotherapy pilots, the allied health professional referral-to-treatment revised guide and the AHP service improvement project are all supporting improvements to access and outcomes, and I will certainly look further at the point that my hon. Friend made about ensuring the provision of such access, when treatment has been delivered outside the NHS, so that people receive the appropriate aftercare.

My hon. Friend also made powerful references to several cases and, in particular, to the one from his constituency, that of Holly Davies, whose life, from my hon. Friend’s own testimony today and from her diary entries, has clearly been transformed by undergoing selective dorsal rhizotomy, SDR, under the care of Dr Tae Sung Park—whom my hon. Friend rightly described as one of the world’s leading paediatric neurosurgeons—at St Louis children’s hospital in Missouri.

Dr Park and his colleagues have pioneered the use of this procedure, which has benefited many thousands of children from throughout the world. We also heard today how Holly’s family have worked tirelessly to raise both awareness of the procedure and the funds to send their daughter to the USA to receive the treatment, and I can well understand the frustration, expressed by hon. Members in this debate, at the sense that the NHS might in some way be denying people access to the procedure.

Of course, those of us who are parents—even those of us who are not—want the best for our children, and in many cases SDR has been shown to improve a child’s comfort and quality of life. Even the simplest day-to-day tasks, such as standing and walking, can be made easier due to the increased flexibility in their limbs, so SDR is a major surgical procedure that aims to reduce the amount of information, as my hon. Friend rightly described, that the sensory nerves carry. As he also said, after the procedure patients need long-term physiotherapy and aftercare, and it is important to ensure that such continuity of care is part of the service that they receive.

The current technique, in which only those nerve rootlets that contribute most to the spasticity are divided, was introduced as far back as 1978, but it is important to stress that SDR is not a cure for cerebral palsy, nor is it suitable for the treatment of abnormal movements or of balance problems. Indeed, it is suitable only for appropriate children, as Members have acknowledged in this debate, after assessment by clinicians. It is therefore unlikely to be suitable for other types of cerebral palsy.

As my hon. Friend will be aware, the Department does not make central decisions or directions on the funding of treatments; it is for local commissioners to decide whether to approve funding for treatments, based on proper consideration of the clinical evidence and—it is important that I stress this—the patient’s individual circumstances.

[Tom Brake]

Given that the Minister and the hon. Member for Daventry (Chris Heaton-Harris), who opened the debate, have identified that a relatively small number of children would benefit from SDR, what role will specialist commissioning or, indeed, the NHS Commissioning Board play in looking at treatment throughout the whole country for those young people?

[Paul Burstow]

My right hon. Friend makes a rather important point. One of the opportunities that the Health and Social Care Act 2012, which we have taken through the House, provides is through the establishment of the NHS Commissioning Board. For the first time, all specialised commissioning will be done in one place and at one level, and, although no decisions have yet been made about the area under discussion, it is one of many, involving rare conditions or where specialist expertise needs to be brought to bear, in which the board can contribute to driving improvement.

Parliament has given the job of assessing the clinical evidence to the National Institute for Health and Clinical Excellence in order to provide clinicians with guidance on the safety and efficacy of procedures. NICE does so through its interventional procedures programme, which is different from the more recently published guidance, to which I shall turn in a moment. NICE’s interventional procedures guidance protects patient safety and supports people in the NHS in the process of introducing new procedures. Many of the procedures that NICE investigates are new, but it also looks at more established procedures of the sort that we are discussing and at issues of safety and how well procedures work. By providing guidance on how safe procedures are and how well they work, NICE makes it possible for new treatments and tests to be introduced into the NHS in a responsible way. NICE’s interventional procedures guidance has a slightly different, but equally important, purpose from that of its other guidance products. Interventional procedures guidance does not provide advice on whether treatments are clinically and cost effective, but it does provide advice on whether such procedures are safe and efficacious enough to use in clinical practice.

As my hon. Friend said, NICE published its updated interventional procedures guidance on SDR for spasticity in cerebral palsy in December 2010 in the light of the emerging evidence base from this country and around the world. NICE’s guidance states that the procedure may be used provided that normal arrangements for clinical governance and audit are in place. While the evidence suggested that the operation can improve the comfort and mobility of some people who have cerebral palsy, it was recognised that there are none the less serious risks that would have to be mitigated and managed as part of the procedure, not least in relation to harm to bladder function and walking ability. NICE was clear that if appropriately trained health care professionals wish to offer this treatment, they must fully explain to the families what is involved and that further surgery and intensive aftercare may be needed. NICE is also aware that the surgical techniques used within this procedure are still evolving, and that is why it has made recommendations about further ongoing research, although my hon. Friend made a very powerful case about the evidence base that has developed in the United States over many years of the treatment’s use in that country.

My hon. Friend will be interested to know that NICE is currently developing clinical guidelines on the management of spasticity in children and young people that will provide guidance to the NHS on whether SDR represents a clinically and cost-effective use of NHS resources. NICE consulted on the draft guidance last October. The draft guidelines explained that the available evidence for the procedure shows that it is most likely to be effective in children with particular symptoms, but that the evidence of sustained benefit was not currently available or weak. That is another area where it says that there is a need for research.

I assure my hon. Friend that I will ensure that this debate is provided to the decision makers within NICE so that they can see the additional material that he has brought to the House’s attention and the contributions of other hon. Members. That is very important. I hope that others who are championing this cause have taken the opportunity to respond to the consultation on the draft guidance. I understand that the final version of the published guidance will come out in June this year.

My hon. Friend referred to the work of Kristian Aquilina in Bristol and touched on the work of Support4SDR. I strongly commend the work that both are doing to raise awareness of SDR as a treatment. I know that in December they had a very productive meeting with officials from my Department, not least Dr Sheila Shribman, the national clinical director for children and young people. I gather that the meeting was useful and that a number of avenues were set out for further pursuit and exploration. Throughout the health and social care system, more information for patients and their families and clinicians can help to ensure that more informed decisions are made. The key challenge for Mr Aquilina and Support4SDR will be to increase the awareness of SDR as a possible treatment for some children with cerebral palsy. At the meeting, a number of possible avenues were suggested, not least engagement with the Royal College of Surgeons, working closely with the Council for Disabled Children, and updating the relevant section of the NHS Choices website. My officials stand ready to continue to engage and to work with those wishing to pursue this.

The issues spoken of tonight are very important because of the impact that cerebral palsy can have on children and their families and the hope of a better future that can be offered by appropriate treatment, which, for some children, might mean SDR. Raising public awareness about the procedure is undoubtedly part of what tonight’s debate has done. I commend my hon. Friend and others for contributing to that and for continuing to do so beyond the debate. I hope that the debate will be a contribution to NICE’s deliberations.

Clearly, promoting SDR as a safe procedure for appropriate children can be done only at a clinician-to-clinician level, so I urge my hon. Friend and others to continue to work with Support4SDR and Mr Aquilina carefully to document and spread the results of this surgery. The compelling stories of those mentioned in the debate, whether it be Holly, or Dana—the constituent of my right hon. Friend the Member for Carshalton and Wallington (Tom Brake)—or Finlay, or many others, all bear testament to how this can make a difference to people’s quality of life. I look forward to seeing the work that is produced by NICE and others in the coming months.

Question put and agreed to.
