My Lords, I rise to speak to Amendments 146, 148 and 149 in my name, and in support of Amendment 151, which the noble Lord, Lord Patel will speak to. These amendments are about keeping in check the cost of running the biggest quango in the country and holding it to account, through published information on its financial and service performance in the main part of its job, which is commissioning NHS services either directly or through clinical commissioning groups. My Lords, I fully accept that it is not common to put budgetary control of new bodies in the Bill that creates them. However, it is not that common to create a new huge quango that will be spending in excess of £80 billion pounds a year. As someone with long experience of quangos, I am only too aware of their capacity to grow their management budgets and roles, often through mission creep and always with plausible reasons for doing so.

When these bodies have regional and local arms, as seems increasingly likely to be the case with the national Commissioning Board, their scope for consuming more taxpayers’ money is only increased. These bodies are notoriously difficult to control in terms of their running costs and their activities over time. The history of British public administration is littered with examples of Parliament setting up bodies and then finding a decade later that they have grown in size and cost much more to run than was originally intended. That is why every so often, under successive Governments, we have culls, mergers and budget cuts to these bodies, as we have seen recently, and it particularly occurs when their running costs clearly become disproportionate to what they are actually delivering.

I do not usually do prediction, but I can predict with absolute certainty that the national Commissioning Board will follow the trajectory I have outlined, whatever well-meaning assurances the Minister gives us and whatever honeyed words are uttered by its chairman and chief executive. Our job in Parliament is to frame the Bill so that they are more likely to deliver those assurances in practice. I suggest that from the outset the Bill should impose constraints on the board’s running costs, not only to ensure that the maximum amount of NHS budget goes on delivery of front-line services but also to thwart the growth of bureaucratic procedures and curb the temptation for the board to become excessively controlling of local initiatives. We are already hearing concerns from clinicians who will be undertaking commissioning about the board becoming too controlling and, some would say, too big for its boots.

It is to these ends that I have framed Amendments 146, 148 and 149. Amendment 146 makes it clear that the board’s annual business plan must clearly state its proposed operating costs. This will enable everyone to see what they are as a proportion of total expenditure and to make comparisons over time. Amendment 148 is the really meaty amendment in this trio because it tries to make clear that from the outset the board’s operating costs are going to be controlled. It proposes that its base operating costs should be 30 per cent lower than those incurred by the predecessor bodies whose functions will be transferred to the board.

The Government say they want to cut bureaucracy—here is an opportunity to show what they are made of. Figures would be audited under this amendment by the National Audit Office but the Secretary of State could change the discount rate of 30 per cent shown in this amendment if he published reasons for doing so. In subsequent years the board’s operating costs could not go up by more than a price increase in line with the consumer price index, unless authorised by the Secretary of State. I am sure there will be lots of arguments about these kinds of amendments being inappropriate in primary legislation and the inflexibility they will cause—well, they are intended to cause a bit of inflexibility—but if the board’s operating costs increased by just 1 per cent of the total expenditure over a number of years, that would be another £1 billion spent on administration rather than service delivery.

In the tight financial climate that all public services face, it is incumbent upon us as parliamentarians to reduce from the outset the risk of the board’s operating costs getting out of control, given the size and scale of its expenditure. Amendment 149 tries to complete the controls by requiring the board’s annual report to include a statement on the financial and service performance of its own commissioning and that of clinical commissioning groups collectively. We need to know on a regular basis what the board is delivering for a given amount of money. If my wording can be improved, I would be delighted, but this is too important and potentially expensive an issue to be brushed aside by vague assurances. I promise the Minister I shall be terrier-like on this particular issue.

My Lords, I recognise from everything the noble Lord, Lord Warner, said that these amendments have been proposed with the best of intentions. I start by making it clear that an independent, accountable, transparent and efficient NHS Commissioning Board is a key component of our proposals, so I hope I can reassure the Committee on these issues. In doing so, I hope my Lords will forgive me if I touch on similar ground to that covered during the debate on Schedule 1.

Let me first assure the Committee that we want to reduce the amount of NHS funding spent on back-office bureaucracy. Indeed, as we stated in last year’s White Paper, the NHS simply cannot continue to afford to support the costs of the existing administrative structure. Management costs in PCTs and SHAs more than doubled in the decade up to 2009-10, to £1.85 billion, increasing by more than £220 million in 2009-10 alone.

The noble Lord, Lord Warner, posed the question: what is different this time? Well, I believe a great deal will be different, and that is exactly why Clause 21 provides the Secretary of State with the power to set a limit on the use of resources by the board itself and by the board and CCGs together in relation to administrative matters. The meaning of what is to be considered as administrative matters will be defined through parliamentary regulations for the first time. The board has the power to set similar limits for individual CCGs. The changes that we are making will cut the overall cost of administration by one-third, and Clause 21 gives us the legislative basis to do that.

The Bill includes clear procedures around the publication of the board’s annual accounts, annual reports and performance assessments of CCGs; and I hope that I can provide reassurance in this area as well. The requirement to publish an annual report applies to all of the board’s functions, including its commissioning and financial functions and its performance assessments of clinical commissioning groups. The board is also under a separate duty to publish a report each year containing a summary of the results of each performance assessment. So I do think that the provisions in the Bill already address the concerns embodied in Amendments 146, 148 and 149.

On Amendment 151, which is grouped here, the board’s power in new Section 13X(b),

“to acquire and dispose of property”,

is necessary for the board to acquire any premises that it needs to accommodate itself for the purpose of carrying out its functions. Likewise, should it find itself with property surplus to its requirements, it would need to be able to divest itself of that property. The power simply replicates the power that PCTs currently have.

My noble friend Lady Tonge asked about the costs of transition. The modernisation programme will have one-off costs of between £1.2 billion and £1.3 billion, spread over the lifetime of this Parliament. It will reduce expenditure on administration by £1.5 billion a year from 2014-15 onwards. That is reducing the administrative spending across the system by one-third, and over this Parliament the modernisation will save £4.5 billion gross, or £3.2 billion to £3.3 billion net. So the up-front costs are expected to be more than recouped by the end of 2012-13. With those explanations, I hope that the noble Lord, Lord Warner, will be somewhat reassured. I am sure that I have not completely reassured him, but I hope that I have done so sufficiently for him to withdraw his amendment.

Can the noble Earl explain to us, in writing, the comparison between the current costs of the bodies carrying out functions that are going to be transferred to the board, and what the Government’s current estimate is of the first year’s fully fledged activities of the board in discharging those functions? It would be very helpful and certainly more convincing to me and, I suspect, other Members of this House if we could see the comparative figures just for the board. I am not asking him to go into Monitor or CQC; I am asking for the figures just for the board taking on the functions that it will be taking on.

Secondly, his response did not really deal with the issue of how you keep these costs under control as the years go by. Is he relying only on the Secretary of State being eagle-eyed and briefed by his civil servants to do it, or do the Government have in mind an uprating mechanism that would curb unnecessary growth in this area?

This is one area where the Secretary of State has a direct interest to ensure that administrative costs are kept low. In answer to the noble Lord’s first question, of course I would be happy to write. There is already a great deal in the impact assessment, to which I would direct noble Lords’ attention. However, I shall be happy to write an individual letter to him and copy it to noble Lords in answer to the questions that he posed.

My Lords, I wonder whether I could chip in, starting with an apology. As a result of the apparent abandonment of the previous set of amendments, I did not realise that this one had started and, therefore, have not followed everything that has been said. My remarks will be correspondingly brief. However, I have heard enough to know that I want to declare my general broad sympathy with the thrust of what the noble Baroness, Lady Williams, proposes and to link myself with the remarks that have just been made by the noble Lord, Lord Hunt, and not least those that were made while I was in the Chamber by the noble Lord, Lord Owen. They all echo something that I, and my noble friend Lord Mawhinney, have tried to say on a number of previous occasions—that there is beginning to be an absence of realism in the Government’s attitude to some of these matters. As I have said several times—and as has been said in other ways by other Peers during this debate—at the end of the day the House of Commons will not accept a Secretary of State who says, “Nothing to do with me, guv”, when something has clearly gone seriously wrong.

If the Secretary of State judges that something is happening that is not in the best interests of the health service, I do not see how he can fail to do something about it; and if he does not have a clear power to do something, I can tell you what will happen. The Government will scratch around in every corner of the Act until they find something that enables them to do something, because the Secretary of State will not be able to tell the House of Commons that he can do nothing. There is a real danger that the Government will immolate themselves, in this House at least, on the basis of an absurd proposition that the Secretary of State can somehow stand back and wash his hands of things when they are going wrong. I hope that this amendment will not be pressed to a Division tonight, because I do not think it would be sensible. We need to reflect on what the Minister says, but he needs to reflect on what is being said to him and to be prepared to come back with something different on Report.

My Lords, I am beginning to feel sorry for the Minister. He is getting a kicking from both sides of him, left and right, and in front. I am puzzled by this amendment and the arguments being put forward, both the one by my noble friend Lord Hunt, and the one in the names of the noble Baroness, Lady Williams, and the noble Lord, Lord Marks. The reason why I am puzzled is because I keep coming back and looking at this Bill, particularly at Clauses 17 and 20. I know that the Minister did not think much of my restrictions on the number of items in the Secretary of State’s mandate under Clause 20, but let us set that aside for the moment. Let us assume that the Secretary of State does exactly what my noble friend Lord Hunt does and lays out a very large number of items, and not what David Nicholson does, listing them on one side of A4.

The beauty of the mandate is that it has to be related to money and the Secretary of State can, in certain circumstances, change the mandate. He also has considerable powers to make standing rules changes under Clause 17. So I am slightly puzzled about the set of circumstances that my noble friend and the noble Lord, Lord Marks, are making for this additional provision. I am interested to hear what the Minister says about why this additional requirement may be necessary, because of the inadequacies of the combined effects and powers of Clause 20 and Clause 17.

Lord Hunt of Kings Heath Portrait Lord Hunt of Kings Heath
- Hansard - - - Excerpts

Perhaps I could try to answer my noble friend. There are two reasons why this is important. First, there is a real risk that the mandate will become so large and extensive to cover the Secretary of State—who wishes to transfer responsibility to the national Commissioning Board—that we will end up with a real fudge about who is actually responsible. Secondly, there are circumstances. Until last week, I do not think that many people knew that once a trust had allowed its waiting times to go beyond 18 weeks, there was a problem with some of them taking their eye off the ball. If a patient missed the target, often he might have to wait for weeks. It is quite possible that even if the mandate is as extensive as I suggest it might be, there will be circumstances in which the Secretary of State may need to intervene. It is not the case of having time to rewrite or edit the mandate, or look at the standing rules. The Secretary of State may need to intervene on the day that an issue arises. All that I want to do—and I suspect the noble Lord, Lord Marks, also wants this—is to make sure that the Secretary of State is able to intervene in circumstances that we cannot necessarily anticipate but, knowing the health service, we suspect will arise from time to time.

My Lords, my Amendment 154 brings us to a group of amendments which consider a number of interesting points about clinical commissioning groups and their relationship with GPs, other contractor services and local authorities. They also allow us an early canter at probing exactly where the Government’s policy on clinical commissioning groups currently is.

My first Amendment 154 is partly probing, but it is also to ask why membership of a clinical commissioning group is only confined to general practitioners or, in the jargon of the Bill, providers of primary medical services. What about the other contractor professions within primary care: the dentists, the pharmacists and the ophthalmologists? What about primary and community nurses? I would not in any way seek to undermine the potential leadership role of general practitioners, but they are part of a primary care team. It is rather unfortunate that other members of the primary care team were not considered worthy of membership of a clinical commissioning group.

I must say that I have yet to hear any rational explanation as to why GPs only have been singled out for this exalted membership of a clinical commissioning group. It would have been perfectly possible to have brought all the contractor professions and, I would hope, primary care nurses, into membership of a clinical commissioning group, and then to have a governance structure which none the less recognised the pivotal role of GPs but did not exclude the other professions. One could have had a weighted voting system or some other way of reflecting that yes, GPs are clearly a very important profession in primary health care, but they are not the only one.

I am curious to know why the Government did not adapt that approach, and how they expect clinical commissioning groups to really relate to the other professions. How can they bring them on board? I think of rural clinical commissioning groups and rural dispensing, and how there can be terrible tensions between GPs who dispense in rural areas and community pharmacists in those areas. If I were a community pharmacist, I would be rather concerned that the rural clinical commissioning group is not at all going to act in the interest of community pharmacy. It is almost bound to act in the interest of rural dispensing general practitioners.

I would be interested therefore, if the noble Earl, Lord Howe, could give some further explanation as to the construct of clinical commissioning groups. I should say to him that, having talked to dentists and community pharmacists, they are really concerned that they will be excluded from the decision-making process within clinical commissioning groups, and that it will be purely GP-dominated. Some of the people most concerned, and quite rightly, are primary care nurses, whose voice should be heard. One fears that the traditional approach will be to exclude them from those discussions when they have an enormous amount of expertise to bring to the table.

Amendment 158 is a probing amendment. It relates to the areas of clinical commissioning groups and argues that clinical commissioning groups ought to be coterminous with the boundaries of a local authority or contiguous group of local authorities.

I stress to the noble Earl, Lord Howe, that this is a probe. If health and well-being boards are to work well, there clearly needs to be an integration of public health and commissioning between the various groups at local level to make sure that they come together in a cohesive plan and at interventions. It is very important that clinical commissioning group areas at least do not go over into other local authority boundaries. There is an argument for coterminosity, but of course I do accept that in some areas that would make the clinical commissioning groups far too large and that is why I stress to the noble Earl that this is a probing amendment.

In the county, non-metropolitan district areas where you still have a two-tier system, I would have thought there is some concern about the involvement of the non-metropolitan district councils in the arrangements for liaison between local government and clinical commissioning groups. While it does not strictly come within the remit of this amendment, it is a matter to which I suspect we will want to return at Report stage.

Beyond that, this is a good opportunity to ask some serious questions about clinical group commissioning. It seems to be clear that there is now increasing anxiety among GPs that the likelihood of them having significant control of commissioning is becoming remoter by the day. The noble Earl will be aware of the BMA’s decision to come out decisively against the Bill. But I have also noted with great interest a press release by the NHS Alliance, which of course has been very much a flag waver for the Government, in which it complained about bullying taking place by the system in relation to clinical commissioning groups. The headline is that doctors leading the NHS reform changes report coercion and bullying in the way the organisations are being set up, which followed a survey of a number of pathfinder clinical commissioning groups. The survey asked: “Do you believe that your clinical commissioning group is being coerced or bullied in how you are setting up in ways that conflict with what you feel would benefit your local population?” Out of the 67 clinical commissioning groups surveyed, 60 per cent answered yes. So much for this hands-off approach that we have been promised. Clearly things have changed. When this started the assumption was that we would have a large number of clinical commissioning groups covering fairly small areas where GPs would actively be involved around the table in commissioning decisions. It has been made abundantly clear that CCGs would not be authorised unless they merged into much larger organisations covering very large population bases.

I wonder whether the noble Earl could perhaps say how many clinical commissioning groups he now expects to be informed. Can he also confirm that they are going to be forced to obtain external commissioning support? Indeed, they have been promised the delight of a bureaucratic procurement process for that support lasting, I understand, up to 12 months. So they are also clearly being leaned upon to use the private sector for such support and they are being forced also to merge commissioning for large-scale commissioning projects. No wonder some GPs are beginning to wonder what this is really all about and whether one beast is being replaced by another. Today Dr Michael Dixon, the chair of the NHS Alliance, told the annual conference about the challenges ahead for clinical commissioning groups or, as he called them, the nation’s future clinical commissioners. He said that they will be confronted by the demons of self-interest, factional politics, ignorance, laziness and raw emotion. They will be hated by all of those who have fed from the gravy train of the current system.

I am a longstanding admirer of Dr Dixon, not least because of his pressure when I was in government to give support to complementary medicine, which I suspect that noble Earl, Lord Howe, now enjoys as well. But I think he made those remarks because he knows, deep in his heart, that the game is up. Whatever one thinks of the Government’s reforms and whatever changes have been made as a consequence of the listening exercises, I had always clung to the thought that the Government were serious about giving GPs control of commissioning. It has become abundantly clear that this is not the case. GPs have been sold a dupe and so too has Parliament, I fear. I beg to move.

I speak to Amendment 157 which is aimed at containing the number of clinical commissioning groups and their total operating costs. I have some sympathy with the remarks made by my noble friend, but before I go into the detail of these particular amendments, I want to give a little context.

My Lords, there has been a great deal of concern expressed by many people who are well versed in the background and activities of the NHS about the number and small size of clinical commissioning groups that might emerge. I do not condone bullying, but we have a problem. The smallest population size for a CCG that I have come across is 18,000 for Radlett, near Watford. I asked the Minister for the Government’s latest estimate of the number of clinical commissioning groups likely to be operational in April 2013. In his answer to me on 9 November, he said:

“It is too soon to estimate the number of clinical commissioning groups that will be operational in April 2013. There are, however, currently 266 pathfinder CCGs covering 95% of GP practices in England”.—[Official Report, 9/11/11; col. WA 58.]

So it is possible that there could be about 280 clinical commissioning groups when all practices are covered. This is far too many to be effective, for reasons I will explain in a moment. We are getting into an extraordinary position. It seems almost an article of faith, or really bold ministerial courage, for the Government to be embarking on this massive NHS reorganisation, at a time of great financial challenge, without knowing, 16 months before they go live, how many clinical commissioning groups—the bodies that will be handling large chunks of this money—will be in place. That seems a pretty racy way to live with a national icon like the NHS.

We will come to the competency tests for CCGs in later amendments. If those competency tests are to mean anything, a significant number of these groups could, presumably, flunk them. Or will all the geese suddenly become swans? What light can the Minister throw on the likely failure rate for clinical commissioning group applicants? When will we have more reliable data on how many clinical commissioning groups we are likely to end up with? For the purposes of discussing the amendment, I will assume that the Government anticipate having something of the order of 250 clinical commissioning groups by April 2013. For many of us, this would seem far too many, and totally fails to learn the lessons of history. As someone who had to learn the lessons of history in the area of commissioning the hard way, I want to share some of that experience with the House.

In 2002, the previous Government set up 302 primary care trusts to undertake commissioning. To some extent, in doing this, it was following the course that this Government are trying to pursue—of getting commissioning closer to local populations. That was one of the arguments for doing it and it is not one which I would quarrel with, in principle. But, like clinical commissioning groups, small PCTs were expected to be able to carry out most of the functions of a commissioner. They needed to have all the skills to undertake commissioning, they needed to be effective demand managers, they had to have the muscle to stop acute hospitals gobbling up too much of the money and they had to be able to secure a more appropriate balance between community-based and hospital-based services in their delivery. They failed, and their failures were shown by a number of reports by the Health Select Committee in the House of Commons. They failed because many of them were simply too small and there were too many of them for the commissioning capability nationally available to be able to staff and run that number of bodies. We are heading down exactly the same path with clinical commissioning groups. The manifestation of the failure of the PCTs was the financial meltdown of the NHS in 2005-06. This meltdown occurred after several years of 5 per cent real terms growth in NHS expenditure and in the middle of a financial year with 5 to 6 per cent real terms growth. This is not the situation that clinical commissioning groups will be faced with.

My Lords, is not the whole point of the formation of clinical commissioning groups that it should be a local solution that fits the configuration of a particular urban or rural area and that it should be decided locally with the Commissioning Board what the best fit is? I take the point made by the noble Lord, Lord Warner, that size is an important issue as to whether one is favouring individual GP commissioning of a personal family health service or whether one is going for the much bigger purchasing of population services. Surely the big difference with this Bill is that PCTs had no real central support for developing commissioning in the way that clinical commissioning groups will have very explicit support from the Commissioning Board. I can see that the noble Lord, Lord Warner, is shaking his head, but I think that makes a huge difference because we have seen the concentration of emphasis by the Department of Health on the acute sector, and to get a way towards having much greater leadership from the centre in developing commissioning seems to me a very positive thing.

The noble Lord, Lord Hunt of Kings Heath, asks why is it only GPs—why do all professionals not get involved? All local primary care clinical professionals should have an input to the groups’ deliberations, but surely the obvious answer is that it is GPs who specifically use resources for their patients from secondary care. They actually determine the costs in secondary care through their use of secondary care hospitals; they intervene to stop secondary care—they have the possibility of doing it through provision of primary care; and they have enormous control over the funding, potentially, of the hospital system. It seems absolutely obvious that it should be GPs. The input of local dental practitioners, opticians and pharmacists is vital but they do not play the same financial role and that is why it seems to me it has to be GPs.

We cannot in this Chamber fix this Bill to lay down rules for the development of clinical commissioning groups. It would be absurd. The Commissioning Board and local people who are going to contribute to it have to make that decision. They have to be the ones to make it work. If they need to come together to commission services for rare conditions, that is fine.

Lord Warner Portrait Lord Warner
- Hansard - -

There are very few things in health policy on which I disagree with the noble Baroness. However, this House needs to look at what the evidence base from GP fundholding and practice-based commissioning shows us. The evidence base shows that GPs did quite well in commissioning some services. However, their actual impact on reshaping services out of acute hospitals was virtually zero. There have been some very good evaluations of GP fundholding and some less good evidence from practice-based commissioning. These showed that GPs got very close to their patients, understood what they wanted and reshaped some services. The transaction costs were seriously high in GP fundholding, which demonstrated that doing good commissioning requires a lot of data collection and analysis, which does not come cheap.

We need to understand the issue of muscle. People like the Nuffield Trust have done some good work on this. At the end of the day, the GP commissioners we have had so far were not strong enough and did not have big enough budgets or the analytical capabilities to call the shots with acute hospitals. That is the bottom line. I strongly support GP commissioning in principle. However, we are in danger of repeating the mistakes of the past and not learning from those experiences.

I do not disagree with the noble Lord, Lord Warner. It is absolutely true that there is a balance and that size is important. Nevertheless, at the moment we are going back to a size that is approximately the same as the old district health authorities that we had between 1983 and 1992. They survived for quite a long time—

I thought I would get my question in before the noble Lord gets warmed up again. He said there is no indication from the evidence from the past of what the right size for a PCT was, but there is some evidence from the past. I do not think that there was ever constructed a PCT of under 100,000 population, which compares with 18,000 in Radlett for a CCG. If you actually look at what happened when we asked PCTs and SHAs to work together and engage in local consultation in 2005-06 on reformulating PCTs, the general thrust of what they came forward with was twofold: it was to be bigger in size and to be a better match with the boundaries of the upper-tier local authorities, which were the social services authorities. So there was some evidence that people themselves, when engaged in an exercise of reorganisation, moved towards bigger organisations and coterminosity with social care authorities.

Earl Howe Portrait Earl Howe
- Hansard - - - Excerpts

Earlier on I noted that the noble Lord drew parallels between CCGs and his attempts when he was a Minister to reduce the number of PCTs. I do feel there is a critical difference. The decision to establish a certain number of PCTs was taken in Richmond House by Ministers. I am not saying those decisions were arbitrary—of course they were not—but they certainly were not bottom-up. With CCGs, the onus is on GP practices to determine the most appropriate size and configuration for their local population. As I have said, the board will then rigorously assess whether this proposal will result in the CCG being able to fulfil its functions. That is a judgment, but it is a proper fitness for purpose test which PCTs never had to go through. I simply do not accept that, come April 2013, there is likely to be a raft of CCGs failing. If a CCG’s proposed constitution is not robust, then it will not receive full authorisation.
