Inaugural address Maarten van der Elst: The voice of the patient

The use of technology is unavoidable to keep healthcare affordable and accessible, but its implementation must go hand in hand with respect for patient values, says trauma surgeon Maarten van der Elst. He has been appointed to TU Delft’s Reinier de Graaf chair for the coming five years and is one of the leaders of the Medical Delta Living Lab ResearchOR. He is holding his inaugural address on 4 March.

“The healthcare sector is literally out of money, so if we don’t make it more efficient and cheaper soon, we will end up creating a real social divide, with enormous waiting lists and debates about whether procedures like cataract or hip operations are really necessary,” says trauma surgeon and professor Maarten van der Elst. “The population is ageing and people live longer with chronic disorders like cardiovascular diseases, HIV and diabetes. This means there are more and more people who need care, but less and less people who can or want to provide it. With the help of technology, we can keep healthcare affordable and accessible to all.”

Da Vinci surgical robot

A photo of an operating theatre with a Da Vinci surgical robot demonstrates his point: a modern hospital is already a high-tech environment. “When you find yourself on such an operating table, you fully realise that you are surrendering yourself not only to doctors and nurses, but also to all the equipment they use. You can only hope that the staff are properly trained in the use of the system and that it functions correctly and is regularly maintained,” says Van der Elst. “Lasers, electrosurgical instruments, high-frequency echoes and the like all have their advantages, but they also all pose risks.”

So how can we use smart technologies to make healthcare safer for patients? That is one of the questions Van der Elst will be addressing in the coming years. It is a question that poses quite a challenge. “Based on figures from abroad, we estimate that each year some six thousand patients in the Netherlands suffer serious damage as a result of a potentially preventable healthcare incident; 1500 of these die as a result. There are various causes of this: diagnostic or medication errors, infections, falls, but also technological failures.” So there is plenty of subject matter for research. The renowned ECRI Institute in the US publishes an annual top ten of technological risks in healthcare, ranging from loose bolts and screws to unproven robotic surgical techniques.

When you find yourself on such an operating table, you fully realise that you are surrendering yourself not only to doctors and nurses, but also to all the equipment they use.

Patient values

However, safety is not the only important factor in the development and application of technology in healthcare. “Safety is very important, but other patient values also need to be explicitly taken into account when introducing new healthcare technologies,” says Van der Elst. “Patients want to keep a certain degree of autonomy, they want privacy and they want to be treated with dignity and compassion,” he gives as examples. “We can use technology to facilitate self-management of chronic conditions, help people to live at home for longer and improve their quality of life, which are all things that patients value.”

Nonetheless, this important issue is receiving too little attention at the moment. “New technologies in hospitals are currently very industry-driven. Moreover, the technologies that are promoted as the best solutions often also turn out to be the more expensive ones.” This is unsurprising if you consider the high development costs of medical technology, or MedTech, but according to Van der Elst this is putting the cart before the horse. “Some people even come to me and say: ‘Look what I’ve developed; do you have a patient for it?’ But that’s not the way it works. We should judge a new technology based on its value for the patient and the patient’s quality of life, and its usefulness for the professional. For example, does it make a surgical procedure less painful or easier to perform?”

But the interests of society must be taken into account too. “Healthcare costs make up a significant part of public expenditure, so you have to be able to justify that the money is being put to good use. Does the new technology really make treatment more efficient and cheaper?” For example, a Da Vinci surgical system costs €2.5 million. “To this you can add thousands of euros per operation for the use of the sterile casings. So there has to be convincing evidence that such a robotic procedure is much better than an ordinary operation,” says Van der Elst. “Our chair will enable us to investigate the usefulness of such new technologies or critically examine the evidence provided by others.”

The robotisation of healthcare will certainly not stop with the Da Vinci robot. Transferring tasks from hospital staff to robots can resolve a lot of the current challenges in healthcare, Van der Elst thinks. Stock management, for example, is a task that healthcare staff should not have to concern themselves with. “Logistics in supermarkets and Ikea stores are fully automated, so why does it all have to be done manually in a hospital? This work can all be done automatically using sensors.” Transferring such tasks to robots has another important advantage. “Staff get frustrated because they can only spend 60% of their time providing actual care. If technology can assume all those tedious administrative and stock management tasks, or make the beds, the nurses will have more time for the patients. And this will attract young people back to the healthcare sector.”

"Several Clinical Technology students are doing an internship with us. Just like the BioMechanical Engineer, a Clinical Technologist develops new technology in a 'patient-driven' way. The Clinical Technologist has medical knowledge as well as technical knowledge. Together with the doctors they develop and improve care equipment in accordance with the patient values. TU Delft, together with Leiden and Rotterdam (in the Medical Delta context, ed.) trains these clinical technologists We collaborate a lot with students and researchers from BioMechanical Engineering and Clinical Technology students of biomedical engineering, for example, present their research findings to the hospital staff and then receive very critical questions, making both types of engineers a major contributor to safety and efficiency in healthcare. "

Compassion

Robotisation need not stand in the way of compassion either, thinks Van der Elst. “I personally wouldn’t mind if a robot washed me, or if a robotic bed carried me to the radiology department, if that gave the nurse more time to come and have a chat with me.” He knows from experience that many patients feel the same way. A good example is Reinier the Robot, which was recently deployed in the geriatric department. Reinier can play word games with patients and even get them dancing. “That little robot can help keep people mentally and physically fit, plus – and this is important – the nurses can easily reprogram it themselves.” Reinier can practise proverbs with the elderly people on the ward and dance the Macarena with them, and in the paediatrics department he can sing children’s songs or do the Dab.

“If used smartly, technology can make a real contribution to a more compassionate care environment,” says Van der Elst. “But you have to take the patient’s opinion into account.” Innovations therefore need to be developed in consultation with the doctor and the patient. “If the patient is unable to make their wishes clear, because they are under anaesthesia or suffering from dementia, then the doctor must be the voice of the patient.”

I am satisfied if in five years there is a roadmap for every technological innovation in a hospital

The voice of the patient is also the title of the inaugural address he will be holding at TU Delft on 4 March 2020. The new Reinier de Graaf chair builds on twenty years of cooperation between the hospital and TU Delft. “Reinier de Graaf was a physician who made important discoveries in the 17th century. You could say that innovation was in his DNA. Innovation is also in the DNA of Delft’s hospital and university,” says Van der Elst. “We share the same goals: to make healthcare more safe, efficient, effective, customer-focused and accessible.” Van der Elst clearly sees the added value of cooperating with the university. “In this partnership, one plus one is three. We bring technology to the hospital and the hospital to technology,” he says. “For example, biomedical engineering students present their research findings to hospital staff and then receive very critical and useful feedback in return.”

Part of the joint research takes place in the living lab, a specially designed operating room, the Medical Delta Living Lab ResearchOR. “There we can conduct structured and safe tests on all kinds of systems during real life surgery.” One such system involves sensors that allow the work of medical practitioners to be tracked live via a dashboard. “An average hospital has as many as 80,000 instruments in use. They all need to be counted, sterilised and disposed of, which is an awful lot of work. Technology can make a huge contribution to reducing this workload. By fitting all instruments with a transmitter, you can see exactly which instrument is being used when and where and so monitor the entire surgical process. That system is now being tested.”

Roadmap

Van der Elst has a clear idea of what he wants to have achieved by the time he passes the baton to another clinician in five years’ time. “I will be satisfied if by that time there is a roadmap for every technological innovation in a hospital. This will enable us to ensure that we only introduce new technologies that have proven effective, that are more efficient and cheaper, and that take the interests and values of the patients into account. Then we’ll really have achieved something.”
