A smarter approach to the UK’s GP crisis
 
Could the vast and escalating primary care crisis in England be helped with a new and innovative online dashboard, which automatically sends short videos contributed by clinicians to patients’ mobiles to address their FAQs?
 
Dr Seth Rankin an experienced GP thinks it can. Click on the photo below to access a short video, which demonstrates how the dashboard works.

 
 
 

UK’s Secretary of State predicted the healthcare crisis
 
The UK’s Secretary of Health has frequently stressed the urgent need for more innovation in healthcare. In 2015 he said: “If we do not find better, smarter ways to help our growing elderly population remain healthy and independent, our hospitals will be overwhelmed – which is why we need effective, strong and expanding general practice more than ever before in the history of the NHS.
 
An easy and effective way to improve GP services

Most patients don’t remember half of what is said in short GP consultations. This is why videos are so important. Unlike doctors and pamphlets videos never get tired, never wear out, and are available 24/7, 365 days a year. Unlike the Internet, the dashboard provides premium reliable healthcare information, which easily can be consumed by patients and shared among family, friends and carers. The video content can be viewed many times, from anywhere, and at anytime. The dashboard is fully automated [see figure below], relieves GPs of a lot of unnecessary work, and importantly, reports on how patients’ use the different videos,” says Rankin; CEO of the London Doctors Clinic; and formally the managing partner of the Wandsworth Medical Centre, and co-chair of Wandsworth CCG’s Diabetes Group.
 
A fully automated dashboard to improve efficiency and increase the quality of care
 
 
Reducing unnecessary A&E visits

‘The dashboard uses videos of local healthcare professionals because both patients and doctors want to improve their connectivity. The dashboard is embedded with about 120 short, 60 to 80 second, talking-head videos, which address patients’ frequently asked questions. Research suggests that the average attention span for people watching videos on mobiles is between 60 to 80 seconds. The dashboard has been specifically designed to help increase patients’ knowledge of their condition, propel them towards self-management, slow the onset of complications, lower the number of unnecessary visits to A&E, reduce face-time with GPs, and enhance the quality of care,” says Rankin.
 
Essential behavioral techniques

The efficacy of healthcare education is enhanced by embedded behavioral techniques, which nudge people to change their diets and lifestyles, improve self-monitoring of their condition, and increase adherence to medications.  The HealthPad dashboard benefits from such behavioral techniques.
 
Part of comprehensive communications system

The dashboard has been developed by health professionals with significant patient input, and aims to get effective educational content to the largest number of people at the lowest price possible; and without requiring effort from health professionals to mediate or facilitate the flow of the knowledge. To achieve this the dashboard is not a “lock-in” system, but designed to be easily and cheaply re-engineered to integrate with various other communications systems, see diagram below. The only thing that the dashboard requires is a connection to the Internet. 
 

 
GP surgeries at saturation point

A 2016 study published in The Lancet suggests that between 2007 and 2014 the workload in NHS general practice in England had increased by 16%, and that it is now reaching saturation point. According to Professor Richard Hobbs of Oxford University and lead author of the study, "For many years, doctors and nurses have reported increasing workloads, but for the first time, we are able to provide objective data that this is indeed the case . . . . . As currently delivered, the system [general practice in England] seems to be approaching saturation point . . . . . Current trends in population growth, low levels of recruitment and the demands of an ageing population with more complex needs will mean consultation rates will continue to rise.”
 
More than 1m patients visit GPs every day

A 2014 Deloitte’s report commissioned by the Royal College of General Practitioners (RCGP) suggests that the GP crisis in England is the result of chronic under-funding and under-investment when the demand for GP services is increasing as the population is ageing, and there is a higher prevalence of long-term conditions and multi-morbidities.
 
Each day in England, more than 1m patients visit their GPs. Some GPs routinely see between 40 to 60 patients daily. Over the past 5 years, the number of GP consultations has increased by 60m each year, and now stands at about 370m a year. Over the same period, the number of GPs has grown by only 4.1%.
 
Stress levels among GPs are high and increasing

Deloitte’s findings are confirmed by of a 2016 comparative study undertaken by the prestigious Washington DC-based Commonwealth Fund, which concluded that increasing workloads, bureaucracy and the shortest time with patients has led to 59% of NHS GPs finding their work either “extremely” or “very” stressful: significantly higher stress levels than in any other western nation. GP stress levels are likely to increase.
 
In a speech made in June 2015, the UK’s Secretary of Health said, “Within 5 years we will be looking after a million more over-70s. The number of people with three or more long term conditions is set to increase by 50% to nearly three million by 2018. By 2020, nearly 100,000 more people will need to be cared for at home.” Dr. Maureen Baker, the former chair of the Royal College of General Practitioners (RCGP) has warned that, “Rising patient demand, excessive bureaucracy, fewer resources, and a chronic shortage of GPs are resulting in worn-out doctors, some of whom are so fatigued that they can no longer guarantee to provide safe care to patients.” And Dr  Helen Stokes-Lampard, the new head of the RCGP, warns that patients are being put at risk because they often have to wait for a month before they can see a GP.

 
Newly trained GPs are seeking employment abroad

Trainee GPs are dwindling and young GPs are moving abroad. According to data from the General Medical Council (GMC), between 2008 and 2014 an average of 2,852 certificates were issued annually to enable British doctors to work abroad. We now have a dangerous situation where there are hundreds of vacancies for GP trainees. Meanwhile, findings from a 2015 British Medical Association (BMA) poll of 15,560 GPs, found that 34% of respondents plan to retire in the next five years because of high stress levels, unmanageable workloads, and too little time with patients.
 
5,000 more GPs by 2020

In 2016 the government announced a rescue package that will see an extra £2.4bn a year ploughed into primary care services by 2020. This is expected to pay for 5,000 more GPs and extra staff to boost practices. When the Secretary of Health trailed this in 2015, doctors’ leaders did not view it as a viable solution. Dr Chaand Nagpaul, chair of the BMA’s GP committee, warned that, “delivering 5,000 extra GPs in five years, when training a GP takes 10 years, was a practical impossibility and would never be achieved.” In 2016, Pulse, a publication for GPs, suggested that the Health Secretary understands that he cannot deliver on his election promise of 5,000 new doctors by 2020, and is negotiating with Apollo Hospitals, an Indian hospital chain, to bring 400 Indian GPs to England.
 
Pharmacists in GP surgeries
 
In July 2015 the NHS launched a £15m pilot scheme, supported by the RCGP and the Royal Pharmaceutical Society (RPS), to fund, recruit and employ clinical pharmacists in GP surgeries to provide patients with additional support for managing medications and better access to health checks.
 
Dr Maureen Baker said, “GPs are struggling to cope with unprecedented workloads and patients in some parts of the country are having to wait weeks for a GP appointment yet we have a ‘hidden army’ of highly trained pharmacists who could provide a solution”. Ash Soni, former president of the RPS suggested that it makes sense for pharmacists to help relieve the pressure on GPs, and said, “Around 18m GP consultations every year are for minor ailments. Research has shown that minor aliment services provided by pharmacists can provide the same treatment results for patients, but at lower cost than at a GP surgery.”
 
Progressive and helpful move
 
The efficacy for an enhanced role for pharmacists in primary care has already been established in the US, where retail giants such as CVS, Walgreens and Rite Aid provide convenient walk-in clinics staffed by pharmacists and nurse practitioners. Over time, Americans have grown to trust and value their relations with pharmacists, which has significantly increased adherence to medications, and provided GPs more time to devote to more complex cases. Non-adherence is costly, and can lead to increased visits to A&E, unnecessary complications, and sometimes death. According to a New England Healthcare Institute report, Thinking Beyond the Pillbox, failure to take medication correctly, costs the US healthcare system $300bn annually, and results in 125,000 deaths every year. 
 
Takeaway

People with complex conditions deserve to be seen by a GP who is not stressed and who can devote the time and attention they need. “Videos could play a similar role to practice-based pharmacists. Both deal with simple day-to-day patient questions, and relieve pressure on GPs, which allows them to focus their skills where they are most needed,” says Rankin.

  • Diabetes UK’s (DUK) 2016 State of the Nation Report calls for diabetes education to be improved
  • Effective education can reduce the vast and escalating burden of diabetes and is significantly cheaper than treatment
  • Traditional diabetes education is failing miserably
  • DUK’s education only reaches a small percentage of people with diabetes
  • Self-management is the only realistic way forward to better diabetes management, but will require a transformation of the current patient-educator relationship
  • Could DUK play a leading role in this transformation?
 
Improving diabetes education to enhance patient outcomes
 
For the past decade at least, the charity Diabetes UK (DUK) has been “calling for governments to do more” to improve diabetes care in order to stem the vast and escalating burden of the condition. Currently, 4m people or 6% of the population are living with diabetes in the UK, and this is projected to rise to 5m by 2025. It is estimated that around 10% of the NHS yearly budget is contributed to the treatment of diabetes; which equates to £10.3bn a year.

The prevalence of type-2 diabetes (T2DM) in particular has been increasing rapidly, and is now one of the world’s most common long-term health conditions. Life expectancy on average is reduced by up to 10 years for people with T2DM. Experts say effective education can prevent the onset of T2DM, help with its management once diagnosed, and slow the onset of complications, such as heart failure, blindness, kidney disease and lower limp amputations. The 2016 DUK State of the Nation report called for diabetes education to be improved.

 
Traditional diabetes education is failing

In the video below Richard Lane, Ambassador and Immediate Past President of DUK, describes the significant improvements in diabetes education since he was first diagnosed in the 1970s, and briefly describes DAFNE (Dose Adjustment For Normal Eating), one of the official UK adult courses for managing type-1 diabetes. Also, a patient with type-1 describes how helpful she found some voluntary diabetes educational courses.
 
 

Notwithstanding individual successes, traditional diabetes education programs are failing to reach a sufficient number of people to be effective in reducing the overall burden of the condition. Only 2% of people diagnosed with type-1 diabetes and 6% with T2DM attend official diabetes educational courses. Each year there are 24,000 early deaths from diabetes-related complications, and also 7,000 avoidable amputations. DUK wants 50% of people living with diabetes to receive education over the next five years.
 
DUK's education and support

DUK spends about 50% of the money it raises annually on diabetes education. Of the £37m it raised in 2015 it spent £8.0m on its “Better Care Everywhere” program that works with healthcare institutions, “to make sure people had access to the 15 healthcare essentials”; £7.0m on its “Not Alone with Diabetes” program, which is its helpline; £1.5m “Reducing the Risk of Diabetes”, which is DUK’s participation in the National Diabetes Prevention Program; and £8.2m, “Growing the Impact of DUK’s Work”, which develops “networks of healthcare professionals,” to “work with local community groups and volunteers all over the country”: a total of £24.7m. 

Here we describe these expenditures as education and support services. 
Despite over £20m worth of diabetes educational and support services delivered by DUK each year, and the £10.3bn spent by the NHS on diabetes care and education, diabetes in the UK remains the largest and fastest growing health challenge of our time. “Diabetes is a very serious and complex health condition that requires constant self-management,” says Chris Askew, DUK’s CEO. 
 
A fundamental transformation is required

Increasing self-management is relevant, especially as resources for diabetes are shrinking as the prevalence of the condition is rapidly increasing, particularly among children. However, achieving effective self-management requires a fundamental transformation of the way diabetes education is delivered. 

It is projected that 66% of people in the UK will have smartphones by 2017. It seems reasonable to assume therefore that the majority of people  living with diabetes will have smartphones by 2017. People regularly use their smartphones for 24-hour banking, education, entertainment, shopping, and dating. Diabetes education has failed to effectively leverage this vast and rapidly growing free infrastructure and peoples’ changed lifestyles to introduce effective educational support systems to enhance the quality of diabetes care, increase efficiency, and improve patient outcomes. Today, mobile technology is part of everyday life and people expect to be connected with their relevant service providers 24-7, 365 days of the year from anywhere. 

Here is just one example of a simple evidence-based  dashboard designed to help re-engineer primary care management of diabetes by (i) increasing the connectivity between health professionals and patients, (ii) enhancing patient knowledge of diabetes, (iii) encouraging people to self-manage their condition, (iv) increasing the efficiency of GP clinics, and in the medium to longer term, (I) keep people out of A&E, and (ii) slow the onset of complications.

At very little cost, such a system could be rolled-out nationally through Clinical Commissioning Groups (CCG), integrated into GP clinics, and provide the basis of a national platform for diabetes education. Once patients and health professionals become engaged and familiar with the initial service offering, CCGs can bolt on additional services to further help people ward-off or manage their diabetes. This follows the model of digital champions, which succeed by using a core service to engage, and build a user base, and then add more services, so continuously increasing their users’ familiarity with their services. Engaging patients and health professionals any other way tends to fail.

The  diabetes education dashboard ensures that people either at risk of diabetes or living with diabetes will always be part of an educator-patient network, which should increase the variety; velocity, volume and value of educational healthcare information patients receive.

 
The escalating incidence of diabetes is not new

Data reported by DUK in 2015 revealed that over the past decade the number of people living with diabetes increased by 60%, and the charity’s leaders claimed that the public health situation in the UK with regard to diabetes is being allowed “to spiral out of control”. “Diabetes already costs the NHS nearly £10bn a year, and 80% of this is spent on managing avoidable complications,” said Barbara Young, then the CEO of DUK. Such findings, while shocking, are not new. 
 

The vast and escalating burden of diabetes

Tackling diabetes is important for the future of the NHS as there are over 4m people living with diabetes in the UK at present. This represents 6% of the UK population, or 1 in every 16 people. About 90% of the cases have T2DM. 90% of people with T2DM are overweight. Lifestyle changes and weight loss can help to prevent T2DM from ever occurring. Obesity is 40% more common among people living in deprived areas. 11.9m people in the UK are currently at risk of developing T2DM, but more than half could delay or even prevent a diagnosis by improved diets and lifestyles. This requires effective education that engages people and encourage them towards healthier lifestyles. About 10% of the cases are Type-1, which usually develops in childhood, and is often inherited. The NHS spends £10.3bn every year on treating diabetes, which equates to 10% of its entire budget. 80% of this is spent on diabetes medication. The annual indirect costs, such as productivity loss and informal care, are estimated to be £13bn. Effective education is cheaper than treatment.

 
The government will not spend more on diabetes

DUK’s repeated calls for the government to do more for diabetes care have been unsuccessful. This is largely because the NHS is struggling to cope with a surge in demand for care while suffering a major budget squeeze. In 2016, the government took back control of overspending semi-autonomous hospitals as part of its crackdown to tackle a NHS deficit of £2.45bn; the biggest overspend in its history.
 
DUK is a significant provider of diabetes education

To look at some aspects of DUK’s educational achievements we have taken a selection of extracts from its 2015 Annual Report. Against each extract is a short comment.

DUK:11,000 people learnt how to better understand and manage their condition through our Type 2 online education course.” 
 
COMMENT: This represents about 0.3% of the people in England diagnosed with T2DM.
 
DUK:Our care line supported 22,361 people who needed encouragement, information or someone to talk to”. 
 
COMMENT: This represents about 0.6% of people in England living with diabetes.
 
DUK:5.9m visits to the Diabetes UK website in 2015 – almost 10 per cent more than the year before – giving people the opportunity to learn more about the condition, what we do and how to get involved.”               
 
COMMENT: The key question here is the quality of the visit to the DUK website. Questions include inter alia: What is the average ‘dwell time’ for each visitor to DUK’s website? How many repeat visits does the website receive? What is the average number of pages viewed by visitors to DUK’S website? What are the most popular website pages viewed? What are the least popular website pages? How many visitors to the website come from the UK? What percentage of the people who visit the website “get involved”? How long do they stay involved? What percentage of the website’s visitors register with the site?
                                            
DUK:15,196 people found out their risk of developing Type 2 diabetes at one of our Roadshows – and can now take steps to avoid it.” 
 
COMMENT: This represents about 0.1% of the people in the UK at risk of T2DM.
 
DUK: “Educated more than 17,000 healthcare professionals to better work with and support those living with diabetes.”
 
COMMENT: Is this cost-effective? Would not online engagement be more appropriate?
 
DUK:11,000 people registered to educate themselves about managing their Type 2 diabetes via our online course Type 2 Diabetes and Me.”
 
COMMENT: This represents about 0.3% of people in England diagnosed with T2DM.
 
DUK:11.9 million people in the UK are currently at risk of developing Type 2 diabetes, but more than half of those people could delay or even prevent a diagnosis . . . In 2015 we worked with NHS England and Public Health England to develop the NHS Diabetes Prevention Programme. This partnership has the potential to help people in England who are at high risk delay – in some cases even prevent – Type 2 diabetes, and is being watched by the rest of the UK with interest.
 
COMMENT: In 2015 the UK government's Public Accounts Committee (PAC) observed that the national prevention initiative, which costs over £35m each year, lacked urgency, and recommended that it should, “develop a better and more flexible range of education support for diabetes patients.
 
A HealthPad Commentary reviewed the national prevention program, described an innovative and successful US diabetes prevention initiative, and concluded that because the UK program employed 19th century technologies to address a 21st century epidemic it would likely fail. The Commentary further argued that preventing T2DM entails winning the battle against obesity, reducing poverty, and changing peoples’ diets and lifestyles. To do this, education programs need to employ modern behavior techniques to engage people and coax them to change their behaviour.
 

A further HealthPad Commentary, described the growing frustration of the government’s PAC and the National Audit Office (NAO) with the country’s diabetes establishment.
 
DUK: Our ‘Know Your Risk’ volunteers helped over 15,000 people find out their risk of Type 2 diabetes at one of our events, while our online tool was used over 240,000 times.”
 
COMMENT: This represents 0.47% and between 6 to 7.5% respectively of people living with T2DM in England.
 
DUK should report costs and outcomes not costs and the distribution of services

Two points about DUK’s statements of its educational achievements:
  1. The majority of the charity’s education and support services only appear to reach a small percentage of the total number of people either at risk of T2DM or those living with diabetes. We have drawn attention to the fact that a large percentage of people with T2DM are over weight and 40% of obese people reside in deprived areas of the UK. To be effective diabetes education must have the Heineken effect.
  2. For the past decade at least, the DUK has tended to report the costs and distribution of its education and support services. More relevant would be for the charity to report costs and the effects its services have had on reducing the burden of diabetes, slowing complications, improving efficiencies, and enhancing patient outcomes.
Diabetes education providers should adopt school performance measures

For years the UK’s state education service has been using pupil outcome measures to rate the performance of its schools. Why is this not the case for diabetes education? Can you imagine if year-after-year millions of children in England were failing their public examinations, and year-after-year education officers only reported the costs and distribution of their services?  Can you imagine if the public education services only taught a very small percentage of the children eligible for education and there was no information about children’s performance in examinations?
 
Would people accept an education report that said, “This year Worthy schools spent £20m on physics teaching, which only reached 0.3% of pupils who would benefit from the subject, and we have no idea what percentage of those that were taught either took or passed the recommended physics exams”?
 
Technologies facilitate and transform diabetes education

With failing education programs people with diabetes are being driven to self-manage their condition with inadequate support. Inexpensive and ubiquitous technologies facilitate this, and increasingly people are demanding tools that track weight, blood pressure, daily exercise and diet. From apps to wearables, healthcare technology lets people feel in control of their health, while also providing health professionals with more patient data than ever before. 
 
With more than 100,000 health apps, rapid growth in wearables, and 75% of the UK population now owning a smartphone, digital technology is well positioned to significantly improve diabetes education and management. Such technologies while ubiquitous, are ineffective if only used as an adjunct to traditional education. Traditional diabetes education programs have failed to introduce widespread digital support strategies, which significantly enhance the quality of care, increase efficiencies, and improve patient outcomes for the majority of people living with diabetes.
 
In the first video below Richard Lane describes how digital technology is helping people self-manage their diabetes. In the second, Lane and a patient diagnosed with T2DM suggest that the biggest challenge for diabetes care is actually engaging people who are either at risk of the condition or living with diabetes. Only once people are engaged do you stand a chance to raise their awareness of the disease, and encourage them to change their diets and lifestyles in order to slow the progression of the condition and even prevent it.

What are the biggest challenges of diabetes care?
 
Changing the patient-educator relationship
 
Self-management of diabetes should not be viewed simply as developing a website and providing a portfolio of techniques and tools to help people living with diabetes choose healthy behaviours. A necessary pre-requisite for effective education to reduce the burden of diabetes is the actual engagement of people who are either at risk of T2DM or living with diabetes. (Where are the national diabetes registers?). Once engaged education should inform and empower people, and provide them with access to continuous self-management support. This is substantially different to the way traditional diabetes education is delivered as it transforms the patient–educator relationship into a continuous, rich, collaborative partnership. A future HealthPad Commentary will describe an innovative and cost effective Mexican mHealth program, which has radically changed the patient-educator relationship by encouraging people, who are either at risk of T2DM or living with the condition, to take ownership of their own health, and become an integral member of their care team.
 
Takeaways

Diabetes is an out of control killer disease, which experts belief could be stemmed, reduced and prevented with effective education that is significantly cheaper than paying for treatment. Current diabetes education programs are failing miserably, and the prevalence of the disease is increasing rapidly, especially in young children.

Diabetes education and support require a radical overhaul to prevent the disease from spiralling out of control and bankrupting the NHS. This needs leadership to shape and drive a new and effective diabetes engagement/education model. Could DUK provide this?

  • Healthcare systems throughout the world are in constant crisis
  • Attempts to introduce digital infrastructure to improve the quality of care, efficiency, and patient outcomes have failed
  • Modern healthcare systems were built on the idea that doctors provide healthcare with meaning and power, but this is changing
  • Advances in genetics and molecular science are rapidly eating away at doctors’ discretion and power
  • People are loosing their free will and increasingly being driven by big data strategies
  • An important new book suggests that a biotech-savvy elite will edit people's genomes and control health and healthcare with powerful algorithms, and that people will merge with computers
  • Homo sapiens will evolve into Homo Deus
 
Future healthcare shock
 
This book should be compulsory reading for everyone interested in health and healthcare, especially those grappling with strategic challenges. Homo Deus: A brief history of tomorrow, by Yuval Harari, a world bestselling author, published in 2016 is not for tacticians responding to their in-trays, but for healthcare strategists planning for the future.

The book is published a year after an OECD report concluded that NHS England is one of the worst healthcare systems in the developed world; hospitals are so short-staffed and under-equipped that people are dying needlessly. The quality of care across key health areas is “poor to mediocre”, obesity levels are “dire”, and the NHS struggles to get even the “basics” right. The UK came 21st out of 23 countries on cervical cancer survival, 20th on breast and bowel cancer survival and 19th on stroke.


Harari pulls together history, philosophy, theology, computer science and biology to produce an important and thought provoking thesis, which has significant implications for the future of health and healthcare. Homo Deus, more than the 2015 OECD Report will make you think.
 
Healthcare’s legacy systems an obstacle for change

While a large and growing universe of consumers regularly use smartphones, cloud computing, and global connectivity to provide them with efficient, high quality, 24-hour banking, education, entertainment, shopping, and dating, healthcare systems have failed to introduce digital support strategies to enhance the quality of care, increase efficiency, and improve patient outcomes.

Why?

The answer is partly due to entrenched legacy systems, and partly because digital support infrastructure is typically beyond the core mission of most healthcare systems. Devi Shetty, cardiac surgeon, founder and CEO of Narayana Health, and philanthropist, laments how digital technologies have, “penetrated every industry in the world except healthcare”, and suggests doctors and the medical community are the biggest obstaclesto change.
 
 
Doctors’ traditional raison d'être is being replaced by algorithms

Notwithstanding, modern medicine has conquered killer infectious diseases, and has successfully transformed them, “from an incomprehensible force of nature into a manageable challenge . . . For the first time in history, more people die today from old age than from infectious diseases,” says Harari.
 
Further, modern healthcare systems were built on the assumption that individual doctors provided healthcare systems with meaning and power. Doctors are free to use their superior knowledge and experience to diagnose and treat patients; their decisions can mean life or death. This endowed doctors and healthcare systems with their monopoly of power and their raison d'être. But such power and influence is receding, and rapidly being replaced by biotechnology and algorithms.

 
Healthcare systems in crisis

This radical change adds to the crisis of healthcare systems, which lack cash, and have a shrinking pool of doctors treating a large and growing number of patients, an increasing proportion of whom are presenting with complicated co-morbidities. Aging equipment in healthcare systems is neither being replaced nor updated, and additionally, there is a dearth of digital infrastructure to support patient care.
  
A symptom of this crisis is the large and increasing rates of misdiagnosis: 15% of all medical cases in developed countries are misdiagnosed, and according to The Journal of Clinical Oncology, a staggering 44% of some types of cancers are misdiagnosed, resulting in millions of people suffering unnecessarily, thousands dying needlessly, and billions of dollars being wasted. Doing more of the same will not dent this crisis.
 
Computers replacing doctors
 
As the demand for healthcare increases, healthcare costs escalate, and the supply of doctor’s decrease, so big data strategies and complex algorithms, which in seconds are capable of analysing and transforming terabytes of electronic healthcare data into clinically relevant medical opinions, are being introduced.
 
Such digital infrastructure erodes the status of doctors who no longer are expected solely to rely on their individual knowledge and experience to diagnose and treat patients. Today, doctors have access to powerful cognitive computing systems that understand, reason, learn, and do more than we ever thought possible. Such computers provide doctors almost instantaneous clinical recommendations deduced from the collective knowledge gathered from thousands of healthcare systems, billions of patient records, and millions of treatments other doctors have prescribed to people presenting similar symptoms and disease states. Unlike doctors, these computers never wear out, and can work 24-7, 365 days a year.
 
The train has left the station

One example is IBM’s Watson, which is able to read 40 million medical documents in 15 seconds, understand complex medical questions, and identify and present evidence based solutions and treatment options. Despite the resistance of doctors and the medical establishment the substitution of biotechnology and algorithms for doctors is occurring in healthcare systems throughout the world, and cannot be stopped. “The train is again pulling out of the station . . . . Those who miss it will never get a second chance”. For healthcare systems to survive and prosper in the 21st century is to understand and embrace “the powers of biotechnology and algorithms”. People and organizations that fail to do this will not survive, says Harari.
 
The impact of evolutionary science on healthcare systems

Roger Kornberg, Professor of Medicine at Stanford University who won the 2006 Nobel Prize in chemistry, "for his studies of the molecular basis of eukaryotic transcription", describes how human genome sequencing and genomics have fundamentally changed the way healthcare is organized and delivered. “Genomic sequencing enables us to identify every component of the body responsible for all life processes. In particular, it enables the identification of components, which are either defective or whose activity we may wish to edit in order to improve a medical condition,” says Kornberg.



 
The new world of ‘dataism’

Harari’s “new world” describes some of the implications of Kornberg’s discoveries, and suggests that evolutionary science is rapidly eroding doctors’ discretion and freewill, which are the foundation stones of modern healthcare systems and central to a doctors’ modus vivendi. Because evolutionary science has been programmed by millennia of development, our actions tend to be either predetermined or random. This results in the uncoupling of intelligence from consciousness and the “new world” as data-driven transformation, which Harari suggests is just beginning, and there is little chance of stopping it.
 
Over the past 50 years scientific successes have built complex networks that increasingly treat human beings as units of information, rather than individuals with free will. We have built big-data processing networks, which know our feelings better than we know them ourselves. Evolutionary science teaches us that, in one sense, we do not have the degree of free will we once thought. In fact, we are better understood as data-processing machines: algorithms. By manipulating data, scientists such as Kornberg, have demonstrated that we can exercise mastery over creation and destruction. The challenge is that other algorithms we have built and embedded in big data networks owned by organizations can manipulate data far more efficiently than we can as individuals. This is what Harari means by the “uncoupling” of intelligence and consciousness.
 
We are giving away our most valuable assets for nothing

Harari is not a technological determinist: he describes possibilities rather than make predictions. His thesis suggests that because of the dearth of leadership in the modern world, and the fact that our individual free-will is being replaced by data processors, we become dough for the Silicon Valley “Gods” to shape.
 
Just as African chiefs in the 19th Century gave away vast swathes of valuable land, rich in minerals, to imperialist businessmen such as Cecil Rhodes, for a handful of beads; so today, we are giving away our most valuable possessions  - vast amounts of personal data - to the new “Gods” of Silicon Valley: Amazon, Facebook, and Google for free. Amazon uses these data to tell us what books we like, and Facebook and Google use them to tell us which partner is best suited for us. Increasingly, big-data and powerful computers, rather than the individual opinion of doctors, drive the most important decisions we take about our health and wellbeing. Healthcare systems will cede jobs and decisions to machines and algorithms, says Harari.
 
Takeaways

For the time being, because of the entrenched legacy systems, health providers will continue to pay homage to our individuality and unique needs. However, in order to treat people effectively healthcare systems will need to “break us up into biochemical subsystems”, and permanently monitor each subgroup with powerful algorithms. Healthcare systems that do not understand and embrace this new world will perish. Only a relatively few early adopters will reap the rewards of the new technologies. The new elite will commandeer evolution with ‘intelligent’ design, edit peoples’ genomes, and eventually merge individuals with machines. Thus, according to Harari, a new elite caste of Homo sapiens will evolve into Homo Deus. In this brave new world, only the new “Gods”, with access to the ultimate source of health and wellbeing will survive, while the rest of mankind will be left behind.

Harari does not believe this new health world is inevitable, but implies that, in the absence of effective leadership, it is most likely to happen.

Can the obesity epidemic learn from the way Aids was tackled?
 
Obesity is a common chronic health challenge, which is serious and costly.It is one of the biggest risk factors for type-2 diabetes (T2DM) and together - obesity and T2DM - form a rapidly growing global diabesity epidemic, which today affects some 9m people in England.
 
Experts forecast the incidence rate of obesity will rise sharply, and bankrupt the NHS. Conventional strategies to reduce obesity and prevent T2DM have failed. According to the Mayo Clinic it is common to regain weight no matter what weight loss treatment methods you try, and you might even regain weight after weight-loss surgery. This Commentary suggests that extra resources are urgently needed to accelerate and broaden innovative obesity research.
  
Efforts to tackle obesity are low priority and fragmented
 
Overweight and obesity lead to adverse metabolic effects on blood pressure, cholesterol, triglycerides and insulin resistance. Risks of coronary heart disease, ischemic stroke, and T2DM increase steadily with raised body mass index (BMI). High BMI also increases the risk of osteoarthritis; sleep apnoea, gallbladder disease, and some cancers. Cancer Research UK predicts that obesity related cancers are expected to increase 45% in the next two decades, causing 700,000 new cases of cancer. Mortality rates will increase with increasing degrees of obesity. It is therefore important that obesity is treated aggressively. According to a 2014 McKinsey Global Institute study, the UK’s Government efforts to tackle obesity are ''too fragmented to be effective'', while investment in obesity prevention is ''relatively low given the scale of the problem''.
 
A multi-generational problem
 
The 2014 Health Survey found that 61.7% of adults in England (16 years or over) are either overweight or obese, and the prevalence of obesity among adults rose from 14.9% to 25.6% between 1993 and 2014. The number of obese adults in the UK is forecast to soar by a staggering 73% to 26m over the next 20 years.

In 2014-15, there were 440,288 hospital admissions in England due to obesity: 10 times higher than the 40,741 recorded in 2004-5. In England one in five children in their first year at school, and one in three in year 6 are obese or overweight. Also, in the past 10 years there has been a doubling of children admitted to hospital for obesity. Over the past three years 2,015 overweight youngsters needed hospital treatment, and 43 of these have had to undergo weight-loss surgery to reduce the size of their stomachs. Today, diabesity is a multi-generational problem, which suggests that far worse is still to come.
 
Costs and spends
 
The UK spends less than £638 million a year on obesity prevention programs - about 1% of the country's social cost of obesity. But the NHS spends about £8bn a year on the treatment costs of conditions related to being overweight or obese and a further £10bn on diabetes.
 
Obesity is a greater burden on the UK’s economy than armed violence, war and terrorism, costing the country nearly £47bn a year, the 2014 McKinsey study found. Obesity has the second-largest economic impact on the UK behind smoking, generating an annual loss equivalent to 3% of GDP. The current rate of obesity and overweight conditions suggest the cost to NHS England alone could increase from £8bn in 2015 to between £10bn and £12bn in 2020.

 
19th century technologies for a 21st pandemic
 
A year after the publication of the McKinsey study, the UK government launched a national Diabetes Prevention Program (DPP) led by NHS England, Public Health England (PHE), and the charity Diabetes UK (DUK). The program offers people at risk of T2DM an intensive personalised course in weight loss, physical activity and diet, comprising of 13 one-to-one, two-hour sessions, spread over nine months, and is expected to significantly reduce the estimated five million overweight and obese people in England, and thereby prevent them from developing T2DM. A previous Commentary predicted that the DPP would fail because it is using a 19th century labour intensive method to address a 21st epidemic.
 
This suggests that the diabesity epidemic will only get worse unless we take more urgent and effective action. A view supported by Majid Ezzati, Professor of Global Environmental Health at Imperial College, London, and the senior author of the most comprehensive review of obesity ever undertaken, and published in The Lancet in April 2016. According to Ezzati, “The epidemic of severe obesity is too extensive to be tackled with medications such as blood pressure lowering drugs or diabetes treatments alone, or with a few extra bike lanes”.

 
Radical action: weight loss surgery
 
The gravity of the UK’s obesity epidemic is demonstrated by the National Institute for Health and Care Excellence (Nice) 2016 suggestion to lower the threshold at which overweight people are offered weight loss surgery. The UK lags behind other European countries in this regard, and experts argue that lowering the threshold would mean the number of people who qualify for weight loss surgery would increase significantly.

According to a report prepared by English surgeons, weight-loss surgery would make people healthier and save the NHS money. The report concluded that after weight loss surgery obese people are 70% less likely to have a heart attack, those with T2DM are nine times more likely to see major improvements in their condition, and also the surgery has a positive effect on angina and sleep apnoea. If all the 1.4m most severely obese people in the UK had weight loss surgery, which costs the NHS around £6,000 per operation, the total cost would be £8.4bn.

 
Weight loss surgery and the brain
 
Initially it was thought that weight-loss surgery worked by reducing the amount of food that can be held by the stomach. However, some patients were found to have elevated levels of satiety hormones, the chemical signals released by the gut to control digestion and hunger cravings in the brain. Patients who had undergone surgery were also found to prefer less fatty foods, which supports the thesis that the hormones also change the patients’ desire to eat, and reinforce the gut brain relationship. This finding reinforces the important link between the gut and the brain on which some of the most promising obesity research is predicated.
 
Gut brain relationship
 
Dr Syed Sufyan Hussain, Darzi Fellow in Clinical Leadership, Specialist Registrar and Honorary Clinical Lecturer in Diabetes, Endocrinology and Metabolism at Imperial College London describes the gut-brain relationship and explains why we eat and why we stop eating:
 

 
Cheap, safe and scalable treatment for obesity
 
The person who has spent most of his professional life searching for cheap, safe and scalable alternatives to weight loss surgery and ineffective weight loss therapies is Professor Sir Steve Bloom, Head of Diabetes, Endocrinology and Metabolism at Imperial College London. Bloom believes that the answer to the UK’s obesity epidemic lies in the gut-brain relationship, and is working on two innovative methods of appetite control, which he and his colleagues believe could significantly reduce the burden of obesity.
 
Method 1: an implantable microchip
 
One method is comprised of a small implantable microchip attached to the vagus nerve to suppress appetite in a natural way. The chip reads and processes both electrical and chemical signatures of appetite within the vagus nerve, and then sends electrical signals to the brain to either reduce or stop eating. Bloom has proven the method’s concept, and in 2013 was awarded €7m from the European Research Council to continue his research. Early findings suggest that chemical rather than electrical impulses are more selective and precise, and the chip reduces both consumption and hunger pangs. All things being equal, it will take another 10 years before this treatment gets to market.
 
Method 2: naturally occurring hormones
 
Bloom is also working on another method to treat obesity, which uses naturally occurring hormones that reduce appetite. Early clinical studies suggest that people will consume 13% fewer calories when they eat a meal after taking the hormones. In 2013 Bloom received £2m from the Medical Research Council to develop this research. One of the significant challenges he faces is hormones normally last only a few minutes in the human body. To overcome this Bloom and his colleagues have had to develop versions of the hormones that can last up to a week before they start breaking down. This suggests that patients could take a single weekly injection to control their appetites. Another approach would be to develop a device, which delivers the hormones continuously. While promising, this method too will take 10 years to get to market.
 
Takeaway: treat obesity the same as Aids
 
Bloom believes that if we approached obesity as we did Aids, the time to develop a cheap, effective and scalable drug for weight control could be cut by half. "The obesity pandemic is the biggest disease that has hit mankind ever in terms  [of] numbers. It is killing more people than anything else has ever killed, . . . . . . . in terms of disease [there are] more deaths from obesity than anything we have known about. The time needed to develop an effective drug could be cut by more than half if conservative checks and balances were loosened. I think we might need to treat obesity in a hurry, and we are being held up. The Aids lobby forced Aids’ drugs on to the market before they had finished testing, but they turned out to be useful and lives were saved. Something similar should be considered for obesity,” says Bloom.

Will the UK’s diabetes prevention program work?
 
Should we entrust the UK’s clinical establishment with preventing type-2 diabetes (T2DM)?

In March 2015 a consortium spearheaded by NHS England, Public Health England (PHE) and Diabetes UK (DUK) - the UK’s clinical establishment - launched the Diabetes Prevention Programme (DPP). A year later, it has come up with Healthier You, an evidence-based program which it hopes will make a significant contribution towards preventing the 5m people in England at risk of T2DM from developing the disease.

 
What will Healthier You achieve?
 
Previous Commentaries have warned that diabetes will not be prevented by repeating past failures. Despite the fact that we know how to avoid and treat T2DM, and despite the fact that over the past decade some £110bn have been spent on diabetes care and education, the incidence rate of the condition has increased by a staggering 65% over the same period. And still each year In England, there are more than 22,000 avoidable deaths, from diabetes-related illnesses.
 
Because the size of the English population at risk of T2DM is so vast, and because Healthier You is using a variant of past diabetes education programs that have failed, it seems reasonable to suggest that while the DPP may have some limited success, it will fail to make a significant reduction to the overall burden of obesity, which devastates the lives of millions and costs billions.
 

Obesity and T2DM are global epidemics

Currently, in England alone some five million people are either overweight or obese, and therefore at high risk of developing T2DM. The economic cost of obesity is £6.3bn, and expected to rise to £8.3bn in 2025 and £9.7bn in 2050. However, this only reflects costs to the health service, and not wider economic consequences for society. In England in 2014, pharmacies dispensed just over half a million items for treating obesity with a net ingredient cost of £15.3 million. All of these prescriptions were for Orlistat, which prevents the body from absorbing fat from food.
 
If current obesity trends persist, one in three people in England will be obese by 2034, and 1 in 10 will develop T2DM. T2DM is a leading cause of preventable blindness, and is a major contributor to kidney failure, heart attack, and stroke. Each year about 120,000 people in the UK are newly diagnosed with diabetes, and there are about 22,000 avoidable annual deaths from diabetes-related causes. In addition to the human cost, T2DM treatment currently accounts for almost 9% of the annual NHS budget: about £8.8bn a year.
 
Similar trends can be seen in the US, where 86 million people are either overweight or obese and therefore have a high risk of developing T2DM. One in every three American adults has prediabetes, a condition that arises when blood glucose levels are higher than normal, but not high enough for a diagnosis of diabetes. There are 30 million Americans living with T2DM, resulting in two deaths every five minutes.

Obesity is a global epidemic. A study published in The Lancet in 2016 found that in the past four decades, global obesity has more than tripled among men and doubled among women. The study says that if current trends continue, 18% of men and 21% of women worldwide will be obese by 2025. According to Majid Ezzati, Professor of Global Environmental Health at Imperial College London, and the study's senior author, “We have transitioned [to] a world in which  . . . .more people are obese than underweight”. 

Diabetes is a global epidemic. Over the past 35 years 314m more people, making a total of 412m, are now living with the condition: 8.5% of adults worldwide. In 2012, 1.5m people died as a result of diabetes, and 2.2m additional deaths were caused by higher that optimal blood glucose.
 
In England, the rising prevalence of obesity in adults has led, and will continue to lead, to a rise in the prevalence of T2DM. This is likely to result in increased associated health complications and premature mortality, with people from deprived areas and some minority ethnic groups at particular risk. Modelled projections indicate that, all things being equal, costs to the NHS and wider costs to society associated with overweight, obesity and T2DM will rise dramatically in the next few decades.

DPP in the news
 
The launch of Healthier You triggered headlines such as, “Personal trainers on the NHS in war on diabetes”, which raised eyebrows and attracted criticism. Despite mounting evidence to suggest that physical activity alone cannot reduce obesity, and despite being attacked by the National Audit Office (NAO) and the Public Accounts Committee (PAC), the NHS, PHE and DUK are convinced that their DPP will be successful. Professor Jonathan Valabhji, national clinical director for diabetes and obesity at NHS England, and one of the leaders of the DPP, says, “The growing body of evidence makes us confident that our national diabetes prevention programme will reduce the numbers of those at risk of going on to develop the debilitating disease”. Is Valabhji right?

Despite a year of planning and the optimism of the DPP leaders, the UK’s Public Accounts Committee has expressed serious doubts about the way the DPP is setting about its task, and has warned that, "By itself, this [the program] will not be enough to stem the rising number of people with diabetes".

 
Successful pilot studies
 
Behavioral interventions, which nudge people to adopt and maintain a healthy diet and lifestyle, can significantly reduce the risk of developing T2DM. Over the past year, seven demonstrator sites set up by the DPP in England have been testing innovative diabetes educational programs, and have reported the reduction of at-risk people from developing T2DM. One pilot that offered two exercise classes a week, and classroom sessions on diet and lifestyle, found that 100% of its participants lost weight, with more than half reducing their diabetes risk. Intelligence from these studies has informed Healthier You. Three quarters of England’s 211 clinical commissioning groups (CCGs) have already joined forces with local authorities, and will now work with four designated providers to offer personal care to those at high risk of developing T2DM.
 
The service providers
 
The four service providers are: (i) Momenta, which offers weight management for adults, and is part of the Reed Partnership that has already delivered over £0.6bn of publicly funded UK contracts, (ii) Pulse Healthcare, which is part of the ICS Group, an established healthcare service provider that offers health and wellbeing services to local authorities, CCGs and employers, (iii) Health Exchange, which was launched in 2006 as a local authority partnership to provide healthy living advice to local community groups, and (iv) Ingeus, which has evolved from a small Australian rehabilitation company in 1989 to an international provider of employment, training and support services.
 
US has similar diabetes prevention program
 
Healthier You is similar to a US diabetes prevention program, which was developed to improve the health of people at risk of T2DM through improved nutrition and physical activity.  In 2011, through funding provided by the Affordable Care Act, the Centers for Medicare & Medicaid Services (CMS) awarded the National Council of YMCA America more than $11.8m to enrol eligible Medicare beneficiaries at high risk of developing T2DM in a program that could reduce their risk.
 
Participants in the American program attended weekly meetings with a lifestyle coach who trained them in strategies for long-term dietary change, increased physical activity, and behavior changes to control their weight and reduce their risk of T2DM. After the initial weekly training sessions, participants could attend monthly follow-up meetings to help maintain healthy behaviors.
 
Over the course of 15 months, participants lost about 5% of their body weight, which, if maintained, is enough to substantially reduce their risk of future diabetes. Over 80% of participants attended at least four weekly sessions. When compared with similar people not in the program, Medicare estimated savings to be $2,650 for each participant over the 15-month period, which was more than enough to cover the cost of the program.
 
In 2016, independent experts found that the American program saved money and improved peoples’ health, and recommended its expansion into US Medicare. "This program has been shown to reduce health care costs and help prevent diabetes, and is one that Medicare, employers and private insurers can use to help 86 million Americans live healthier,” says US Health Secretary Sylvia Burwell.
 
The results of the US diabetes prevention program are promising, although there is no recognized evidence to suggest that exercise alone reduces obesity. Further, not enough time has elapsed to assess whether the program permanently changed the behavior of participants, and whether they maintained their initial loss of weight.
  
No evidence to suggest exercise can tackle obesity

Despite Healthier You’s emphasis on personal trainers, there is no evidence to suggest that exercise has a role in tackling obesity. A 2015 British Journal of Sports Medicine editorial suggests that it was time to “bust the myth” about exercise. According to the Mayo Clinic,Studies have demonstrated no or modest weight loss with exercise alone, and that, an exercise regime is unlikely to result in short-term weight loss”. The benefits of exercise are on insulin sensitivity and aerobic fitness, not weight loss. Exercise is a good way to keep weight off, but a bad way to lose weight. To put it in perspective, exercise burns calories, but substantially less than people often think. For example, 1lb of fat is 3,500 calories, and to burn 1lb of fat you would need to run about 40 miles.
 
19th century methods for a 21st century epidemic

The US experience and the English pilot studies suggest that Healthier You is likely to produce some improvement in the overall situation, but research suggests that this will more likely come from diet rather than exercise. The logistics and scale of the problem are so great that Healthier You is unlikely to have more than a relatively small impact. One-to-one life coaches are expensive, difficult to scale, and costly to administer. Successfully engaging a substantial proportion of the vast and rapidly growing English population at risk of developing T2DM, and nudging them to change their diets and lifestyles will require 21st century technologies. That the DPP has chosen 19th century labour-intensive methods to deal with a 21st century epidemic raises doubts about its efficacy.  Let us explain.
 
Not well planned

Healthier You’s 2016 objective is to identify 22,000 people at high risk of T2DM out of a population of 26m across 27 geographic regions of England, and offer them an intensive personalised course in weight loss, physical activity and diet, comprising at least 13 one-to-one, two-hour sessions, spread over nine months, which is estimated to cost £320 per person, or some £7m each year for the cost of the coaches alone.  

By 2020, the DPP expects to have rolled out Healthier You to the whole country, and each year thereafter expects to recruit 100,000 at-risk people found to have high blood sugar levels. At this rate, it will take 50 years, at a minimum annual cost of some £35.2m, to provide 26 hours of personal coaching for the 5m people at risk of T2DM in England. In addition to the cost, the logistics of effectively delivering and accounting for such a program is a significant challenge. The four designated service providers are expected to join forces with the 211 English CCGs, which are the cornerstone of NHS England, and with several thousand local authorities to deliver each year 2.6m hours of one-to-one personal coaching to 100,000 people at risk of T2DM drawn from an adult population of some 50m, and spread across nearly 60 geographic regions in England. A significant percentage of the beneficiaries will be in full time employment and therefore have time constraints. Another complexity is that each CCG commission’s primary care for an average of 226,000 people, and there are some 8,000 GP practices, which ‘own’ the patient data.

Moreover, the £35.2m annual cost estimate does not include the administrative costs associated with identifying and triaging the 5m at-risk people to recruit annually 100,000 people most at risk who will be offered personal coaching, and monitoring the impact this will have on patient outcomes. It seems reasonable to suppose that Healthier You will be difficult to manage, given that the current NHS primary care infrastructure is at breaking point, with a shrinking pool of overworked and demoralised GPs. It will also be extremely expensive as well as wholly inadequate for the scale of the problem. Recently, Dr Maureen Baker, chair of the Royal College of General Practitioners, said: “Rising patient demand, excess bureaucracy, fewer resources and chronic shortage of GPs [are] resulting in worn-out doctors, some of whom are so fatigued that they can no longer guarantee to provide safe care to patients.

 
Simple arithmetic
 
Did the leaders of the DPP not only over emphasize the potential impact of exercise on obesity, and their ability to manage the program and underestimate the program's costs; but also get their arithmetic wrong in planning the roll out of Healthier You? The DPP leaders must have known that each year for the past 10 years there have been some 100,000 new diagnoses of T2DM. Even if we assume that: (i) there will be no future increase in the incidence rates of obesity and T2DM, (ii) by 2020 Healthier You will be 100% effective in recruiting its annual target of 100,000 at risk people, (iii) Healthier You will be 100% successful in changing the diets and lifestyles of the 100,000 people it recruits each year, and (iv) the annual death rate from diabetes-related causes will remain constant; the conclusion is unavoidable that although the DPP will be spending a minimum of £35m a year to deploy personal trainers, there will still be millions of overweight and obese people, and the incidence rate of T2DM will still be vast and escalating. The T2DM epidemic will not have been dented.
 
 Accountability
 
The UK’s Secretary of State for Health says, “We will be looking closely at the results of this programme.” Does this mean that its leaders will be accountable? To date, the UK government’s record on making people accountable for diabetes care and education is poor.

An earlier Commentary drew attention to the fact that UK diabetes agencies responsible for spending millions each year on diabetes education and awareness programmes which fail, only report on the distribution of services, rather than on the impact those services have had on patient outcomes, which is the most appropriate way of measuring the Healthier You’s effectiveness.  See, The importance of measuring the impact of diabetes care. 

 
Takeaways
 
What will Healthier You achieve?  Given the success of the English pilot studies and the success of the similar American diabetes prevention program, it seems reasonable to expect Healthier You to produce some improvement in the overall situation. However, the scale of the problem is so vast, its management infrastructure so weak, and the impact of exercise on obesity so little, that Healthier You is unlikely to have more than a relatively small impact. The size of the UK population at risk of T2DM is so great that much more modern and efficient tools are needed to get to grips with the problem and make a real difference. A future Commentary will be devoted to describing some of the technological advances being made to tackle obesity and T2DM.
 
Preventing T2DM is too important to be entrusted to our well-resourced clinical establishment that has failed to dent the large and rapidly rising burden of the condition. Preventing T2DM requires leadership and an efficacious strategy, which in the short term, innovates and leverages the use of mobile technologies to engage millions of at-risk people, and nudge them to become permanently enthusiastic about changing their diets and lifestyles; in the medium term, recruits corporates, educational establishments, restaurants, and faith groups into the overall prevention strategy; and in the long term, promotes changes in our environment so that we are obliged to live healthier lives.
