NHS doesn't stand for "National High Street"

Providers in the new NHS must be free to integrate care in the patient interest, even if this has the effect of reducing competition argues Chris Hopson, the new chief executive of the Foundation Trust Network.

On the High Street, competition law creates a competitive market by ensuring a range of different suppliers, fostering competition based on price, avoiding monopolies and probing vertical integration in the supply chain (for example, supermarkets owning dairies).

But there are other models for preserving the consumer interest which recognise that certain areas of our national life have specific characteristics that require a different approach.

Last month, for example, saw a highly publicised row between two train operating companies bidding for a long term, monopoly, franchise. The franchise deliberately runs for long enough to enable the operator to earn a sufficient return on the expensive infrastructure needed to provide a quality customer service.

Last month also saw the closure of the football transfer window, which restricts the times when clubs can buy new players. Clubs also now have to abide by new Financial Fair Play rules which are designed to create a level playing field by restricting the amount of money wealthy owners can invest to "buy success".

What does all this have to do with the NHS? The Health and Social Care Act, passed earlier this year, marks the next stage in the journey away from a single, all encompassing, command and control health service. It continues work begun by the previous Labour administration to create a more plural system where, in some areas of care, a wider range of providers compete to provide services for patients. As a result, patients have greater choice rather than, for example, being forced to use the closest NHS hospital.

But the health sector is not the High Street. Competition is based on quality, not price, with the price of an increasing range of treatments determined by a single tariff, to be set in future by a central Commissioning Board and the sector regulator. There also needs to be a strong emphasis on integrating care, defined by the NHS Future Forum as "integration around the patient, not the system". The Forum went on to argue that "outcomes, incentives and system rules (i.e. competition and choice) need to be aligned accordingly".

It's easy to see why integrating care is so important. An 80 year old frail patient with multiple problems needs a joined-up network of acute and primary care services where geriatricians, nurses, physiotherapists, and podiatrists all understand the individual patient's needs, and the care provided has no gaps - an integrated care pathway.

Diabetic patients in Bolton now have a centre staffed by specialists that care for inpatients at the local hospital but also care for patients at home by working with GPs. The very GPs who, in future, are likely to have commissioned the centre to provide this service. Elderly patients in several Surrey care homes are visited by hospital based geriatricians who advise staff and help to prevent patients being admitted to hospital unnecessarily.

These are all examples of good, joined-up, care: benefitting individual patients, reducing cost and providing better value for money for the taxpayer. But they do involve integration across the NHS, between different organisations that may be commissioning or competing with each other to provide services. Some might argue this reduces competition.

The Foundation Trust Network, which represents the vast majority of acute, mental health, community and ambulance providers in the NHS, is co-hosting fringe sessions at all the party conferences to explore how the NHS can achieve the right balance between integration and competition. It's an important question as the detailed rules for the new NHS are finalised over the next six months.

We'll also be particularly focussed on the importance of the NHS sustaining a flourishing and vibrant set of public providers over the longer term. The way the new rules are formulated will have a crucial impact here. If we get them wrong, there's a danger, to focus on another cause celebre in the competition world, that these organisations could turn into the dairy farmers of the healthcare sector. They might end up working for payments that do not cover costs; forced to sign up to short term contracts that offer no incentive to invest in innovations that improve quality and efficiency and facing an uncertain financial future.

Inside Big Ben: why the world’s most famous clock will soon lose its bong

Every now and then, even the most famous of clocks need a bit of care.

London is soon going to lose one of its most familiar sounds when the world-famous Big Ben falls silent for repairs. The “bonging” chimes that have marked the passing of time for Londoners since 1859 will fall silent for months beginning in 2017 as part of a three-year £29m conservation project.

Of course, “Big Ben” is the nickname of the Great Bell and the bell itself is not in bad shape – even though it does have a huge crack in it.

The bell weighs nearly 14 tonnes and it cracked in 1859 when it was first bonged with a hammer that was way too heavy.

The crack was never repaired. Instead the bell was rotated one eighth of a turn and a lighter (200kg) hammer was installed. The cracked bell has a characteristic sound which we have all grown to love.

Big Ben strikes. UK Parliament.

Instead, it is the Elizabeth Tower (1859) and the clock mechanism (1854), designed by Denison and Airy, that need attention.

Any building or machine needs regular maintenance – we paint our doors and windows when they need it and we repair or replace our cars quite routinely. It is convenient to choose a day when we’re out of the house to paint the doors, or when we don’t need the car to repair the brakes. But a clock just doesn’t stop – especially not a clock as iconic as the Great Clock at the Palace of Westminster.

Repairs to the tower are long overdue. There is corrosion damage to the cast iron roof and to the belfry structure which keeps the bells in place. There is water damage to the masonry and condensation problems will be addressed, too. There are plumbing and electrical works to be done for a lift to be installed in one of the ventilation shafts, toilet facilities and the fitting of low-energy lighting.

Marvel of engineering

The clock mechanism itself is remarkable. In its 162-year history it has only had one major breakdown. In 1976 the speed regulator for the chimes broke and the mechanism sped up to destruction. The resulting damage took months to repair.

The weights that drive the clock are, like the bells and hammers, unimaginably huge. The “drive train” that keeps the pendulum swinging and that turns the hands is driven by a weight of about 100kg. Two other weights that ring the bells are each over a tonne. If any of these weights falls out of control (as in the 1976 incident), they could do a lot of damage.

The pendulum suspension spring is especially critical because it holds up the huge pendulum bob which weighs 321kg. The swinging pendulum releases the “escapement” every two seconds which then turns the hands on the clock’s four faces. If you look very closely, you will see that the minute hand doesn’t move smoothly but it sits still most of the time, only moving on each tick by 1.5cm.

The pendulum swings back and forth 21,600 times a day. That’s nearly 8m times a year, bending the pendulum spring. Like any metal, it has the potential to suffer from fatigue. The pendulum needs to be lifted out of the clock so that the spring can be closely inspected.

The clock derives its remarkable accuracy in part from the temperature compensation which is built into the construction of the pendulum. This was yet another of John Harrison’s genius ideas (you probably know him from longitude fame). He came up with the solution of using metals of differing temperature expansion coefficient so that the pendulum doesn’t change in length as the temperature changes with the seasons.

In the Westminster clock, the pendulum shaft is made of concentric tubes of steel and zinc. A similar construction is described for the clock in Trinity College Cambridge and near perfect temperature compensation can be achieved. But zinc is a ductile metal and the tube deforms with time under the heavy load of the 321kg pendulum bob. This “creeping” will cause the temperature compensation to jam up and become less effective.

So stopping the clock will also be a good opportunity to dismantle the pendulum completely and to check that the zinc tube is sliding freely. This in itself is a few days' work.

What makes it tick

But the truly clever bit of this clock is the escapement. All clocks have one - it’s what makes the clock tick, quite literally. Denison developed his new gravity escapement especially for the Westminster clock. It decouples the driving force of the falling weight from the periodic force that maintains the motion of the pendulum. To this day, the best tower clocks in England use the gravity escapement leading to remarkable accuracy – better even than that of your quartz crystal wrist watch.

In Denison’s gravity escapement, the “tick” is the impact of the “legs” of the escapement colliding with hardened steel seats. Each collision causes microscopic damage which, accumulated over millions of collisions per year, causes wear and tear affecting the accuracy of the clock. It is impossible to inspect the escapement without stopping the clock. Part of the maintenance proposed during this stoppage is a thorough overhaul of the escapement and the other workings of the clock.

The Westminster clock is a remarkable icon for London and for England. For more than 150 years it has reminded us of each hour, tirelessly. That’s what I love about clocks – they seem to carry on without a fuss. But every now and then even the most famous of clocks need a bit of care. After this period of pampering, “Big Ben” ought to be set for another 100 or so years of trouble-free running.
