Lewisham: the most irrational, irresponsible hospital to cut

To cut this well-performing hospital would be to reward failure and punish success.

I was born in Lewisham hospital. My mum was convinced that she’d eaten some dodgy mackerel, but it turned out to be contractions. She was rushed in, and both of us were pretty grateful for the kindness and expertise staff showed in helping a frightened mother deliver a safe birth. So when I heard that Lewisham might be losing most of its maternity and other key services to cuts, I decided to go back and visit.

But walking through the hospital’s glass doors in the bustling heart of South London, I was determined not to be sentimental. Months of covering health news for the Guardian taught me that some closures are inevitable. The left loses credibility by not recognising that. We must be prepared to accept uncomfortable truths. The problem is that this might just be the most irrational, irresponsible hospital to cut:

“Here we are bang in the middle of Lewisham, a real community hospital doing exactly what the government wants,” consultant physician John Miell tells me in the hospital canteen. “We have great health reports from objective sources and our finances are more sound than our neighbours. Now the government are ripping the heart out of this community… If they can close Lewisham, they can close anywhere.”

The facts back him up. Lewisham has ranked in the top forty hospitals in the country for the last four years, and its safeguarding services have just been marked excellent by Ofsted (pdf). Lewisham will not be closing services because of failure; it will be closing to protect other hospitals that are too expensive to close because of bad management and botched PFI contracts. As one doctor put it: “We are victims of our success”.

Matthew Kershaw, the man leading the review, makes no secret of this. He has recommended that Lewisham shut all acute services – children, intensive care and most of maternity – simply so that they don’t compete with others in the South London NHS Trust. It’s the worst example of top-down state control rewarding failure. Weren’t the government’s NHS reforms supposed to be about introducing competition to do exactly the opposite?

If the health secretary Jeremy Hunt agrees to these recommendations on 1 February (or before if rumours are believed that he wants to scupper the demonstration this Saturday), good performance will no longer guarantee any sort of protection against closure. As Lucy Mangan says, every hospital in the country will be at risk.

Doctors are also terrified that the consequences of shutting services in a poor, densely populated inner city area with a booming population and a high birth rate have not been thought through. Campaigners say that the changes will leave the local population of 750,000 with just one A&E department.

“Hospitals to the east and west of Lewisham are already full and have been passing their maternity patients to Lewisham,” says Louise Irvine, a local GP who is leading the Save Lewisham Hospital campaign, “The system is already not coping. People are going to die. That’s what we want Hunt to know. He has been duly warned.”

Doctors told me that the local Queen Elizabeth hospital was already transferring children out as far as Margate to cope with over demand. Mums trying to book Kings hospital for births are already being told there is no space. One GP talked about an appendix rupturing in A&E because they couldn’t be seen in time. These stories came from different local hospitals, but everyone felt their position was too precarious to go on the record.

Distance is another problem. Workers for the London Ambulance Service have informally raised concerns about the closure of Lewisham’s A&E department because they know that minutes determine lifetimes. Jos Bell is one local resident who became active in campaigning to save the hospital because of an experience she had a few years ago when she was taken ill and her pulse stopped:

“I wouldn’t have got to Woolwich (the nearest alternative hospital) in time… I would have died in the cab. People will be dropping on route. They are pioneering new treatments at Lewisham. They have saved my life more than once.”

Distance is a bigger problem in poorer areas where car ownership is relatively low. If Lewisham closes its emergency service, some people in Sydenham and Crystal Palace will have to travel for over an hour to get to recommended alternatives.

“For maternity users it’s going to be the most dangerous,” says Jessica Ormerod, a local mother and head of Lewisham’s maternity committee that represents mums in the borough, “They are already vulnerable. Some asylum seekers don’t have the bus fare to get there – at least they can walk to Lewisham.”

Doctors also raised problems of integration – supposedly another key rationale for the health reforms. Right now if a birth goes wrong unexpectedly, mum can be moved to an emergency service across the hall. But under the new proposals, there would be no facilities to do that. If a baby came out with its chord around its neck, patients would have to be transferred by ambulance across town with all the extra risk that brings. I shudder to think of my mum in this position. That could have been me or my little brother.

“We know that most safeguarding failures occur because of a break down between services as people fall through the gap,” says chair of Lewisham’s clinical commissioning group Helen Tattersfield, who maintains the same problem applies to vulnerable groups like self harmers who need social as well as medical support. “If this goes ahead I’ll have patients in five different hospitals and I won’t know they’ll be in the system. It’s a recipe for confusion.”

Kershaw insists that despite extensive consultation, no “viable alternative solutions or proposals been put forward" to solve the challenges faced by the South London Hospital Trust.

If this move made economic sense, perhaps he would have a point. But the Guardian has reported that Kershaw’s proposals would cost £195m to implement, and only deliver £19.5m savings a year. At a time when Lewisham has just invested millions in services that are doing well, this seems wasteful. If you have to close a hospital, why close the one that is doing best?

For many, this is a political decision. Lewisham is a poor area and as one doctor put it, “There is very little to lose when everyone votes Labour here anyway”. The alternative is to close hospitals in Conservative-held areas like Kent, and MPs like Iain Duncan Smith, Chris Grayling and Julian Lewis have already proven that even Tories can’t justify closures in their own backyard. Some call it “fiscal nimbyism”. Patients and doctors call it understanding the consequences when you’re close to them. Me and my mum can testify to that.

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.
