Some of the biggest changes in the practice of medicine and healthcare over the past 70 years have resulted from improvements in the way diseases and illnesses can be diagnosed and studied. Innovative technologies now allow doctors to discover increasing amounts of detailed information about both the progression and treatment of disease, allowing new treatment options and care pathways.
The most significant developments which are likely to change the face of medicine over the next few decades include:
Day-to-day physiological monitoring technology, driven particularly by the spread of a variety of consumer wearable devices with communication capabilities, has the ability to collect and integrate health information from a variety of sources, both medical and consumer-based. The next generation of wearables is likely to significantly blur the division between technology lifestyle accessory and medical device, as reliable non-invasive sensors for the measurement of blood pressure, blood sugar, body temperature, pulse rate, hydration level and many more become increasingly implemented within these devices. The provision and integration of these derived complex sets of data has the potential to provide valuable information, that enabling a holistic approach to healthcare. The US FDA is currently working closely with industry to facilitate the introduction and effective use of these more advanced devices.
In the UK, the NHS has brought high-quality medical services to every citizen, but often at the cost of long waits for visits to the doctor when a patient is concerned about his health. The introduction of improved access systems, including video-conferencing facilities, electronic health records and AI-powered chatbots, promises to be a powerful and game-changing move. In particular, chatbots systems such as Babylon Health or Ada can provide a highly accessible medical triage procedure, which can alleviate the pressure on over-worked doctors in GP surgeries, and allow those doctors to focus on patients with more serious conditions. With increasing sophistication, these chatbots can potentially provide accurate diagnostic advice on common ailments without any human interaction or involvement. The key concern is, of course, ensuring that the algorithms operate with patient safety foremost, which requires fine tuning to balance between over-caution and under diagnosis.
Following admission to a hospital, a key element of modern medicine is the use of imaging systems for clinical diagnosis, and the main challenge for doctors is to interpret the complexity and dynamic changes of these images. Currently, most interpretations are performed by human experts, which can be time-consuming, expensive and suffer from human error due to visual fatigue. Recent advances in machine learning systems have demonstrated that computers can extract richer information from images, with a corresponding increase in reliability and accuracy. Eventually, Artificial Intelligence will be able to identify and extract novel features that are not discernible to human viewers, allowing enhanced capabilities for medical intervention. This will allow doctors to re-focus on their interaction with patients, which is often cited as the most valued aspect of medical intervention.
The current paradigm for medical treatment is changing through the development of powerful new tools for genome sequencing which allows scientists to understand how genes affect human health. Medical decisions can now take account of genetic information, allowing doctors to tailor specific treatments and prevention strategies for individual patients.
In essence, precision medicine is able to classify patients into sub-populations that are likely to differ in their response to a specific treatment. Therapeutic interventions can then be concentrated on those who will benefit, sparing expense and often unpleasant side effects for those who will not.
Currently, robotic surgical devices are simply instruments that can translate actions outside the patient to inside the patient, often working through incisions as small as 8mm. The benefits of this are clear in terms of minimally invasive surgery, and by allowing surgeons to conduct the operations in a relaxed and stress-free environment. At the moment the robot does not do anything without direct input, but with the increasing development of AI systems, it is likely that in 10 or 15 years, certain parts of an operation such as suturing may be performed automatically by a robot, albeit under close supervision.
It is fiendishly difficult to predict the impact of innovative technological advances on medical practice and patient care. However, the overall message is clear – improvements in front end technology will allow patients to have a greater responsibility for their own personal health and well-being. Increased access to medical practice through innovative and efficient mechanisms will allow doctors to focus their time on the patients identified as suffering from more serious illnesses. Highly trained AI systems can then complement the doctors’ prowess in identifying and diagnosing particular diseases. Finally, treatment options will be highly tailored to individual patients and their conditions, increasing the cost-effectiveness of treatment.
However, each of these technology developments comes with associated costs and challenges. Not least, new technology could fundamentally change the way that medical staff work, requiring new skills and mindsets to effectively transform medical care into a radically new approach.

With surprisingly little fanfare, in October 2018 NHS England became the first health service in the world to routinely offer genetic medicine in the fight to treat cancer.
From that date, hospitals across England have been linked to specialist centres that can read, analyse and interpret DNA isolated from patients with cancer. Through this service, cancer patients can be screened for the existence of key mutations within their tumours that can indicate the best drugs for treatment or to point towards clinical trials of experimental therapies that may be beneficial.
The move marks a big step toward “precision medicine”, which offers more effective therapies that are tailored to individual patients.
Firstly, a quick crash course in cancer biology:
Accordingly, although every cell of a particular cancer is related to the same original “parent” cell, the mixture of cells within a tumour becomes increasingly complex. The idea that different kinds of cells make up one cancer is called “tumour heterogeneity”, and in practice means that every cancer is unique. So two people with, say, lung cancer who are the same age, height, weight, and ethnicity, and who have similar medical histories, will almost certainly have two very different cancers.
By the time a cancer tumour is 1cm in diameter, the millions of cells within it are very different from each other, and each cancer has its own genetic identity created by the DNA in its cells.
This, of course, makes the treatment of cancer incredibly difficult and explains why scientific breakthroughs in the understanding of cancer biology do not always lead to significant improvements in overall survival rates.
Precision medicine is an approach to patient care that allows doctors to select the best treatments for patients based on a genetic understanding of their disease. The idea of precision medicine is not new, but recent advances in science and technology have allowed the ideas to be brought more fully into clinical use.
Normally, when a patient is diagnosed with cancer, he or she receives a standard treatment based on previous experience of treating that disease. But typically, different people respond to treatments differently, and until recently doctors didn’t know why. But now the understanding that the genetic changes within one person’s cancer may not occur in others with the same type of cancer has led to a better understanding of which treatments will be most effective.
At the simplest level, this understanding allows targeted therapy against cancer, in which drugs (quite often complex biological molecules) are used to target very specific genetic changes in cancer cells. For example, around 15–20% of malignant breast cancers contain cells with a higher than normal level of a protein called HER2 on their surface, which stimulates them to grow. When combined with a suitable test, it means that not only can the drug be given to those patients most likely to benefit, but also the drug, with its associated side effects, need not be given to patients who will not benefit from its use.
So genetic medicine has already transformed the treatment of some cancer patients. The advent of widespread genetic medicine within the NHS is likely to lead to significant benefits for cancer patients, including:
• The identification of patients who are most likely to benefit from particular cancer therapy.
• The avoidance of unnecessary treatments that are less likely to work for specific groups of patients.
• The development of novel therapies targeted at specific tumour cells or cellular pathways.
Not only will precision medicine allow the development of precise and effective treatment strategies for cancer patients whilst improving the overall quality of life, but it will also finally destroy the myth of ‘one size fits all’ cancer therapy.
