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?

David Cranston is emeritus Professor of Surgery at Oxford University. As well as publishing academically, he has has also authored books on John Radcliffe, and mentoring.

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.

Why end of life agony is not a good reason to allow death on demand

Assisted dying and the unintended consequences of compassion.

Those advocating Assisted Dying really have only one strong argument on their side – the argument from compassion. People who have seen relatives dying in extreme pain and discomfort understandably want to avoid that scenario. Surely the best way is to allow assisted dying as an early way out for such people to avoid the agony that such a death involves?  

Now it’s a powerful argument. To be honest I can’t say what I would feel if I faced such a death, or if I had to watch a loved one go through such an ordeal. All the same, there are good reasons to hold back from legalising assisted dying even in the face of distress at the prospect of enduring or having to watch a painful and agonising death.  

In any legislation, you have to bear in mind unintended consequences. A law may benefit one particular group, but have knock-on effects for another group, or wider social implications that are profoundly harmful. Few laws benefit everyone, so lawmakers have to make difficult decisions balancing the rights and benefits of different groups of people. 

It feels odd to be citing percentages and numbers faced with something so elemental and personal and death and suffering, but it is estimated that around two per cent of us will die in extreme pain and discomfort. Add in the 'safeguards' this bill proposes (a person must be suffering from a terminal disease with fewer than six months to live, capable of making such a decision, with two doctors and a judge to approve it) and the number of people this directly affects becomes really quite small. Much as we all sympathise and feel the force of stories of agonising suffering - and of course, every individual matters - to put it bluntly, is it right to entertain the knock-on effects on other groups in society and to make such a fundamental shift in our moral landscape, for the sake of the small number of us who will face this dreadful prospect? Reading the personal stories of those who have endured extreme pain as they approached death, or those who have to watch over ones do so is heart-rending - yet are they enough on their own to sanction a change to the law? 

Much has been made of the subtle pressure put upon elderly or disabled people to end it all, to stop being a burden on others. I have argued elsewhere on Seen and Unseen that that numerous elderly people will feel a moral obligation to safeguard the family inheritance by choosing an early death rather than spend the family fortune on end of life care, or turning their kids into carers for their elderly parents. Individual choice for those who face end of life pain unintentionally  lands an unenviable and unfair choice on many more vulnerable people in our society. Giles Fraser describes the indirect pressure well: 

“You can say “think of the children” with the tiniest inflection of the voice, make the subtlest of reference to money worries. We communicate with each other, often most powerfully, through almost imperceptible gestures of body language and facial expression. No legal safeguard on earth can detect such subliminal messaging.” 

There is also plenty of testimony that suggests that even with constant pain, life is still worth living. Michelle Anna-Moffatt writes movingly  of her brush with assisted suicide and why she pulled back from it, despite living life in constant pain.  

Once we have blurred the line between a carer offering a drink to relieve thirst and effectively killing them, a moral line has been crossed that should make us shudder. 

Despite the safeguards mentioned above, the move towards death on the NHS is bound to lead to a slippery slope – extending the right to die to wider groups with lesser obvious needs. As I wrote in The Times recently, given the grounds on which the case for change is being made – the priority of individual choice – there are no logical grounds for denying the right to die of anyone who chooses that option, regardless of their reasons. If a teenager going through a bout of depression, or a homeless person who cannot see a way out of their situation chooses to end it all, and their choice is absolute, on what grounds could we stop them? Once we have based our ethics on this territory, the slippery slope is not just likely, it is inevitable.  

Then there is the radical shift to our moral landscape. A disabled campaigner argues that asking for someone to help her to die “is no different for me than asking my caregiver to help me on the toilet, or to give me a shower, or a drink, or to help me to eat.” Sorry - but it is different, and we know it. Once we have blurred the line between a carer offering a drink to relieve thirst and effectively killing them, a moral line has been crossed that should make us shudder.  

In Canada, many doctors refuse, or don’t have time to administer the fatal dose so companies have sprung up, offering ‘medical professionals’ to come round with the syringe to finish you off. In other words, companies make money out of killing people. It is the commodification of death. When we have got to that point, you know we have wandered from the path somewhere.  

You would have to be stony-hearted indeed not to feel the force of the argument to avoid pain-filled deaths. Yet is a change to benefit such people worth the radical shift of moral value, the knock-on effects on vulnerable people who will come under pressure to die before their time, the move towards death on demand?  

Surely there are better ways to approach this? Doctors can decide to cease treatment to enable a natural death to take its course, or increase painkillers that will may hasten death - that is humane and falls on the right side of the line of treatment as it is done primarily to relieve pain, not to kill. Christian faith does not argue that life is to be preserved at any cost – our belief in martyrdom gives the lie to that. More importantly, a renewed effort to invest in palliative care and improved anaesthetics will surely reduce such deaths in the longer term. These approaches are surely much wiser and less impactful on the large numbers of vulnerable people in our society than the drastic step of legalising killing on the NHS.
