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.

Understand what we thirst for

Whether for water or meaning, it’s a primal force.

Quenching thirst is a global problem. It can also be profoundly personal, impaired by illness. For nurses, it can be ethically and emotionally difficult, when treating dying patients. But is there ultimate relief? 

Thirst is the subjective sensation of a desire to drink something that cannot be ignored. The world is thirsty; globally, 703 million people lack access to clean water. That’s 1 in 10 people on the planet. 

Thirst is a life-saving warning system that tells your body to seek satisfaction through swallowing fluid. It works in partnership with other body processes - such as changes in blood pressure, heart rate and kidney function - to restore fluid, and salt, levels back to where they belong. Failure of any part of this beautifully balanced system leads to dehydration (or water intoxication), and perhaps to seizures, swelling of the brain, kidney failure, shock, coma and even death. 

Sometimes it’s difficult to quench thirst, because of problems with supply. According to the World Health Organization, at least 1.7 billion people used a drinking water source contaminated with faeces in 2022. Sometimes in war, water is weaponised, with systematic destruction of water sources and pipes. Water laced with rat fur, arsenic and copper has meanwhile been reported in prisons across the USA.  

At other times, there may be “water everywhere, but not a drop to drink” because of individual problems with swallowing. As a nurse, some of my most heartbreaking moments have been when I have been unable to fulfil a need as basic as a patient’s thirst; when even thickened fluids have led to intense coughing and distress, and a realisation that I can only moisten mouths and give so-called “taste for pleasure”: very small amounts of a favourite liquid or taste using a soft toothbrush, or a circular brush gently sweeping around the mouth and lips to release some of the liquid - even, and especially, at the end of life when the patient is unconscious. 

Difficulties in drinking are common in dementia when fluid can seem foreign and swallowing a surprise to the system. It’s thought that over 50 per cent of people in care homes have an impaired ability to eat or drink safely; 30 to 60 per cent  of people who have had a stroke and 50 per cent of those living with Parkinson’s may struggle to swallow. 

Other conditions that may affect swallowing include multiple sclerosis, cerebral palsy, and head and neck cancers. Diabetes is characterised by a raging thirst owing to problems with insulin (diabetes mellitus) or an imbalance in antidiuretic hormone levels (diabetes insipidus). In intensive care, patients are predisposed to thirst through mechanical ventilation, receiving nothing by mouth, and as a side effect of some medications. But thirst is a “neglected area” in healthcare, writes palliative care researcher Dr Maria Friedrichsen.  

“Knowledge of thirst and thirst relief are not expressed, seldom discussed, there are no policy documents nor is thirst documented in the patient’s record. There is a need for nurses to take the lead in changing nursing practice regarding thirst.” 

Is there another thirst that is also being missed in nursing, and in life in general – a spiritual thirst, beyond the physical desire to drink? In his book, Living in Wonder, writer Rod Dreher argues that humans are made to be spiritual, and that a critical sixth sense has been lost in a “society so hooked on science and reason”. We humans crave love in our deepest selves; we have an insatiable thirst for everything which lies within – and beyond – ourselves. Auschwitz survivor Viktor Frankl, who was later appointed professor of psychiatry at the University of Vienna, became convinced that human beings have a basic “will for meaning.” “The striving to find a meaning in one’s life,” he wrote, “is the primary motivational force in man.”  

In the harsh sun of a Middle East day, an ancient story of a man and a woman encountering each other at a water well illustrates this dual thirst for water and meaning. The man, Jesus, thankful for a drink of water given to him at the well by an outcast Samaritan woman, said that “Everyone who drinks this water will be thirsty again, but whoever drinks the water I give them will never thirst. Indeed, the water I give them will become in them a spring of water welling up to eternal life.” In that midday sun, such imagery made a powerful statement.  

Being mindful of spiritual thirst when drinking water is something also captured in a Ghanaian proverb and pictured perfectly in the many birds that drink by gravity, so tipping their heads back when they swallow.  

“Even the chicken, when it drinks, 

Lifts its head to heaven to thank God for the water”. 

Unsatisfied thirst is part of the human condition, we long for something more; it’s living proof of our immortality, says French poet Charles Baudelaire. Despite his Olympic success, athlete Adam Peaty said that society didn’t have the answers he was seeking, and that a gold medal was the coldest thing to wear. He “discovered something that was missing” when attending church for the first time, and now has a cross with the words “Into the Light” tattooed across his abdomen, symbolizing his spiritual awakening. We are more than mechanical machines with physical needs. We are rather gardens to tend in a dry and thirsty land, with souls in need of intensive care.
