The healing touch in an era of personalised medicine

As data powers a revolution in personalised medicine, surgeon David Cranston asks if we are risk of dehumanising medicine?

In 1877 Arthur Conan Doyle was sitting in one of Dr Joseph Bell’s outpatient clinics in Edinburgh as a medical student, when a lady came in with a child, carrying a small coat. Dr Bell asked her how the crossing of the Firth of Forth had been on the ferry that morning. Looking sightly askance she replied;

“Fine thank you sir.”

He then went on to ask what she had done with her younger child who came with her.

Looking more astonished she said:

“I left him with my aunt who lives in Edinburgh.

Bell goes on to ask if she walked through the Botanic Gardens on the way to his clinic and if she still worked in the Linoleum factory and to both these questions she answered in the affirmative.

Turning to the students he explained

“I could tell from her accent that she came from across the Firth of Forth and the only way across is by the ferry. You noticed that she was carrying a coat which was obviously too small for the child she had with her, which suggested she had another younger child and had left him somewhere. The only place when you see the red mud that she has on her boots is in the Botanic Gardens and the skin rash on her hands is typical of workers in the Linoleum factory.

It was this study of the diagnostic methods of Dr Joseph Bell led Conan Doyle to create the character of Sherlock Holmes.

A hundred years later and I was young doctor. In 1977 there were no CT or MRI scanners. We were taught the importance of taking a detailed history and examination. Including the social history. We would recognise the RAF tie and the silver (silk producing) caterpillar badge on the lapel of a patient jacket. We would ask him when he joined the caterpillar club and how many times he had had to bail out of his plane when he was shot down during the war – a life saved by a silk parachute. We would notice the North Devon accent in a lady and ask when she moved to Oxford.

The patient’s history gave 70% of the diagnosis, examination another 20% and investigation the final 10%. Patients came with symptoms and the doctor made a presumptive diagnosis – often correct - which was confirmed by the investigations. Screening for disease in patients with no symptoms was in its infancy and diseases were diagnosed by talking to the patients and eliciting a clear history and doing a meticulous examination. No longer is that the case.

At the close of my career, as a renal cancer surgeon, most people came in with a diagnosis already made on the basis of a CT scan, and often small kidney cancers were picked up incidentally with no symptoms. The time spent talking to patients was reduced. On one hand it means more patients can be seen but on the other the personal contact and empathy can be lost.

Patients lying in in bed have sometimes been ignored. The consultant and the team standing around the foot of the patient’s bed discussing their cases amongst themselves. Or, once off the ward, speaking of the thyroid cancer in bed three or the colon cancer in bed two. Yet patients are people too with histories behind them and woe betide the medic, or indeed the government, who forgets that.

With computer aided diagnosis, electronic patient records and more sophisticated investigation the patient can easily become even more remote. An object rather than a person.

We speak today of more personalised medicine with every person having tailored treatment of the basis of whole genome sequencing and knowing each individual’s make up. But we need to be sure that this does not lead to less personalised medicine by forgetting the whole person, body mind and spirit.

Post Covid, more consultations are done online or over the telephone -often with a doctor you do not know and have never met. Technology has tended to increase the distance between the doctor and patient. The mechanisation of scientific medicine is here to stay, but the patient may well feel that the doctor is more interested in her disease than in herself as a person. History taking and examination is less important in terms of diagnosis and remote medicine means that personal contact including examination and touch are removed.

Touching has always been an important part of healing. Sir Peter Medawar, who won the Nobel prize for medicine sums it up well. He asks:

‘What did doctors do with those many infections whose progress was rapid and whose outcome was usually lethal?

He replies:

'For one thing, they practised a little magic, dancing around the bedside, making smoke, chanting incomprehensibilities and touching the patient everywhere.? This touching was the real professional secret, never acknowledged as the central essential skill.'

Touch has been rated as the oldest and most effective act of healing.

Touch can reduce pain, anxiety, and depression, and there are occasions when one can communicate far more through touch than in words, for there are times when no words are good enough or holy enough to minister to someone’s pain.

Yet today touching any patient without clear permission can make people ill at ease and mistrustful and risk justified accusation. It is a tightrope many have to walk very carefully. In an age of whole-person care it is imperative that the right balance be struck. There’s an ancient story that illustrates the power of that human connection in the healing process.

When a leper approached Jesus in desperation, Jesus did not simply offer a healing word from safe distance. he stretched out his hand and touched him. He felt deeply for lepers cut off from all human contact. He touched the untouchables.

William Osler a Canadian physician who was one of the founding fathers of the Johns Hopkins Hospital in Baltimore, and ended up as Regius Professor of Medicine in Oxford, said:

“It is more important to know about the patient who has the disease than the disease that has the patient”.

For all the advantages modern medicine has to offer, it is vital to find ways to retain that personal element of medicine. Patients are people too.

Here's why we need to keep democracy holy

It's much more than a utilitarian deal that benefits the most.

George Pitcher

George is a visiting fellow at the London School of Economics and an Anglican priest.

One of the more ludicrous constitutional contributions of late has been the parliamentary petition, with well past two million signatures when I last looked, demanding another general election be called, because the Labour government, elected in July, has “gone back on the promises they laid out in the lead-up to the last election.”

Prime minister Sir Keir Starmer has surprised precisely no one by saying that he won’t be calling one. And so we’ll move on. But, in passing, what is truly breathtaking is how little our democracy is understood and, apparently, how unseriously democracy in the west is now taken. If that sounds unduly censorious, I have a two-word response: Two million!

Little time need be spent on demolishing the premise of this spurious petition, other than to wonder how many of those signatories would have appeared on one calling for, say, a fresh mandate after the coalition government of David Cameron and Nick Clegg (where is he now? Ah yes) performed a massive reverse-ferret on a manifesto pledge not to raise university tuition fees.

Or how many of these same fearless electors believe the result of the Brexit referendum should be voided because of the lies of the Leave campaign, most notable the one painted on the side of Boris Johnson’s battle bus. But no – two million residual, self-righteous righties can only be mobilised against a Labour government.

This event none the less raises valid questions about what our democracy is (and is not) and why we should want to protect or even cherish it. These questions become the more critical because there’s a tangible feeling of slippage in western democracy, as if we’re growing a bit tired and even contemptuous of it.

There’s the ominous re-growth of nationalism across Europe. And not a few bien pensants – me included, to my shame – might admit to a feeling after Donald Trump’s re-election as US president that democracy is too important to be left to the people.

Slightly more seriously, we need to ask ourselves what the qualities of democracy are that we should seek to defend. The first of these is, quite obviously, the rule of law. Should a political actor seek to overthrow a democratically established electoral process, then that is a crime within the rule of law. Witness the horrors on Capitol Hill in Washington DC on January 6 2021.

That’s the Feast of the Epiphany as it happens, but nothing to do with the coming of wise men. With Trump at the centre of it. Draw your own democratic conclusions – and weep for the rule of law.

Natural justice is to ensure that vexatious petitions don’t overthrow legally elected governments, either by lobby or violence.

Again, why does this matter and what is it about democracy that we hold sacred, even holy? It can’t simply be that we hold dear a kind of hard utilitarian ideal that what we elect to do is for the benefit of most of the people, for most of the time, as decided by popular mandate among the demos.

If we believe in democracy, as I believe most of us do, we’re presented with a choice: We can look to secularism as a solution, universal Enlightenment principles built on citizenship and equality before the law. Or we can look to a multiculturist model, keeping the peace between essentially separate communities and the state.

Or we can shape something on Augustinian Christianity, that recognises the limits of political democracy, which would eschew undemocratic theocracy, but which would hold that no political order other than the Body of Christ (the Church) can claim divine authority.

We’re in classic Rowan Williams theological territory here: “[T]he Body of Christ is not a political order on the same level as others, competing for control, but a community that signifies, that points to a possible healed human world.”

Unsurprisingly, I buy that. Williams goes further to state this spiritual effect on the political environments in which we find ourselves is likely to be “sceptical and demystifying.” Which seems to be a reasonable manifesto in a democracy.

The principle of election can be a worrying one in theological terms. We don’t “elect” God, though some secularists would claim that the Godhead is our invention. Rather, it has sometimes been perceived to be the other way around historically.

Reformational Calvinism would hold, among many other things, the rather terrifying view that we’re elected by God. “The Elect” are those who will be saved, while the rest of us (I presume) can rot in hell. Little democracy there.

Less deterministically, a more modernist worldview would argue that the Christian faith, on which foundation western civilisation is built, offers a viable moral definition of the lawful state, with which politicians of all (democratic) persuasions can tackle issues of global justice.

One such issue of natural justice is to ensure that vexatious petitions don’t overthrow legally elected governments, either by lobby or violence. That’s an important aspect of Christian witness and will require true grit in in its application during the years ahead. That’s, if you will, our grit in the democratic oyster.
