“The term ‘primary care’ is a misnomer. The first thing citizens and patients do is think what they can do for themselves, the second is to seek advice from friends and family, and in the last twenty years, the internet. Then they seek professional help.”
Professor Sir Muir Gray
“New concepts like pre-primary care are important ...this is the right discussion to have as we seek new approaches to building a genuinely 21st Century health service.”
Rt Hon Jeremy Hunt,
The Secretary of State for Health (England)
Globally healthcare is under pressure. Developed countries are struggling to meet demand and developing nations are battling to retain healthcare professionals to deliver the most basic services.
The challenge for all is how to provide access and quality at an affordable price. For centuries doctors’ waiting rooms have remained unchanged - a time defying tableau - queues of people waiting for medical wisdom delivered face to face. The face-to-face consultation remains the gold standard for primary healthcare globally but the human tide descending on primary care practitioners is fracturing the status quo.
This report looks at how digital technology can help enable and equip a new type of provision. The traditional definitions of primary and secondary care have served us well but in a world of under-resourced and underfunded health systems is it time to define a new area of appropriate, trusted and safe provision? We need to develop a concept of pre-primary care to release the power of technology. This report sets out to make the case for creating a pre-primary care sector and describes how it will contribute to redefining global healthcare.
The 20th century was the century of the doctor, the 21st century is the century of the patient.
The term ‘primary care’ is a misnomer. The first thing citizens and patients do is think what they can do for themselves, the second is to seek advice from friends and family, and in the last twenty years, the internet. Then they seek professional help.
Healthcare is what people do themselves, what we call primary care is the first level of professional care but neither it nor specialist services have grasped the implications of the internet.
The genome is often portrayed as the disruptive innovation, but the mobile phone is much more disruptive, opening up information, giving citizens access to the best current knowledge and offering new opportunities for patients and new challenges for professionals.
The key question for all 21st century industries, including health services, to ask is, in the words of Bill Gates: “What is the function of the human being?” It is not to give information or communicate the implications of a decision about an operation. These tasks and many others can be better done using technology. The function of the human being is to provide empathy but to do this they need to make a huge jump to understand how their role has changed with the advent of what this report describes as pre-primary care.
We are in the third healthcare revolution after the public health and the high tech hospital revolutions and this is driven by three forces – citizens, knowledge and digital technology, epitomised by the smart phone.
Sir Muir has worked in the NHS since 1972. He was Director of the UK National Screening Committee, founded the National Library for Health and was NHS England’s first Chief Knowledge Officer. Together with Sir Ian Chalmers, he was instrumental in establishing the Cochrane Collaboration
As executive chairman of Your.MD I am proud to present our pre-primary care manifesto.
Your.MD is defining pre-primary care, a new and uncontested market based on personalised, trustworthy and actionable health information to complement doctors, the scarcest resource in the healthcare system.
“Pre-primary care is the most important piece of primary care as it is what happens before the patient ever goes to see a doctor and, in many cases, prevents them from having to actually see a doctor”, Molly Coye M.D. former Chief Innovation Officer of UCLA Health and Social Entrepreneur in Residence at the Network for Excellence in Health Innovation.
We have created a breakthrough end-to-end Artificial Intelligence (AI) platform for pre-primary care because there are not enough doctors in the world to deliver healthcare to everyone, a basic human right (article 25 UN Charter of Human Rights).
Pre-primary care is one of the biggest markets in the world, yet it is one of the least recognised. Everyone needs healthcare.
The Your.MD pre-primary care platform:
• helps people understand what’s wrong with them
• connects them with the most relevant healthcare service providers in their area All using AI and technology so it is completely scalable.
Our aim is to build the biggest healthcare company in the world to help every human being have basic healthcare without owning any hospitals or doctors.
“For physicians who trained 20 to 30 years ago it is hard to believe that patients want these services and they are uncomfortable with these new ways of working but for young doctors they are right there already.”
Dr Molly Coye, Social Entrepreneur in Residence at the Network for Excellence in Health Innovation
The world of healthcare is changing. Developed and emerging healthcare systems are being assaulted equally by ageing populations, a tsunami of chronic conditions and increasing demand for the best technological advances.
Western medicine still favours treating illness over promoting wellness and its medical professionals are trained to diagnose, treat and cure rather than prevent. It is an industry not in collapse but at the peak of its scalability. It is a system rooted in bricks and mortar and the bureaucracy that comes with billion pound budgets and profits.
In developing countries ageing is less of a problem but chronic conditions like diabetes and asthma are hitting already chronically under-resourced healthcare systems struggling to provide rudimentary primary care to their populations.
The evidence suggests we live in a world where our existing models of healthcare are both “financially unsustainable and inequitable. 1”
In the words of Dr Fred Hersch, Chief Medical Officer of Telenor Health based in Bangladesh, neither world can “treat themselves” out of the problem 2.
“The smart phone is shaping up to be the dominant computing platform and it’s not hard to imagine that developing countries will leapfrog the PC era in much the same way that mobile communications leapfrogged fixed land lines.”
Dr Fred Hersch, Chief Medical Officer of Telenor Health
There comes a point when you have to fix what’s wrong with you before criticising others. The proverb “Physician heal thyself” encapsulates the sentiment and perhaps the motto of the pre-primary care movement – “Patient Heal Thyself”.
Patients in the developed world are quick to criticise healthcare system failures but not so prompt in correcting their own behaviours that exacerbate the burden on healthcare budgets.
In nationalised health economies like the NHS patients see it as their right to use the system they have paid for and in privatised systems consumers see it as a necessity to get their money’s worth. Different systems same behaviours, driven by different perspectives.
Your.MD – AI Personal Health Assistant
The goal of Your.MD is to democratise healthcare and place a doctor in the pocket of every citizen in the world. Using artificial intelligence the Your.MD application is learning from its users every day. Benchmark tests have shown medical accuracy at 85% for the 20 most common conditions. Medical accuracy for a further 500 conditions now sits at more than 60%.This makes Your.MD the most accurate symptom checker in the market today. Your.MD’s medical accuracy is benchmarked for diagnostic accuracy using externally verified medical test cases from Harvard University and the Royal College of General Practitioners. This is the same method used to test trainee doctors.
Your.MD has also created its own test cases that hold greater relevance to its global database of users, so testing can be more diverse and thus more accurate. Eventually, Your.MD aims to have a case for every condition so Your.MD will be medically more robust.
In developing healthcare systems, populations face scarcity of resources and disparity in provision between rural and urban areas. As a result, millions around the world already care for themselves and would value medical assistance that could be placed in their hands.
What if, in the developed world, we enabled citizens to be more responsible and accountable for their own health? What if our doctors told us we all had to take our blood pressure, weight and pulse before coming to see them?
What if, in the developing world, we trained one person in every village, armed them with a mobile phone, miniaturised testing equipment and showed them how to appropriately diagnose, treat and triage members of their community?
How is asking someone to prepare for a medical appointment different from the substantial assistance we now give to the airline industry in conducting its business: we book online, order our food and seats online and we print out tickets. When we reach the airport we increasingly check ourselves in and, lately, even check in our own bags. Our banking and shopping experiences are no different. Self-checkout at supermarkets is ubiquitous. Our service industries are now less service more self-service. With these examples citizens have been happy to trade contact and familiarity for convenience, utility and savings even if that means new inconveniences further along the customer journey.
How is skipping the primary care stage in the developed world any different from Kenya skipping over universal banking and going straight to mobile money? Paradigms change in order for the world to progress. Developing a concept of pre-primary care represents a paradigm shift for healthcare globally.
Dr Eric Topol, author of The Patient Will See You Now, says medicine has long been dominated by a “priestly class”, beginning with Imhotep, the first physician (and a priest), in Egypt some 4,600 years ago. Things have hardly changed. Two millennia later Hippocrates, widely considered the father of medicine, insisted that most medical information should be concealed from patients.
As a result, citizens continue to sit in waiting rooms with ailments seeking reassurance, diagnosis and treatment. In the 21st Century, if you want a trusted medical opinion you make an appointment with a professional who has had at least seven to 12 years’ training and is backed by an infrastructure that allows them to empirically prove their medical hypothesis through tests. In developing nations, you either suffer, wait or trek to see trained physicians that are mostly concentrated in urban areas.
It is an inefficient system with the primary care physician acting as a gatekeeper to wider healthcare in most systems. Although many countries operate a system of self-triage to specialist primary care physicians the starting point is always a doctor in a room with a stethoscope no matter what the ailment is, its severity or its longevity.
This approach works as long as you have enough physicians to deal with patients in a timely way. If every individual went to the doctor’s surgery once a year even with the growing population the historical approach might hold the line. However, as populations grow and people live longer with chronic conditions the number of consultations per health professional escalates.
The NHS now estimates that the average citizen sees a nurse or general practitioner five-and-a-half times a year, up from three times in the mid 1990s.3 In India, it is estimated that a primary health centre, which is usually run by one doctor, will be responsible for 30,000 residents4.
Over the past ten years, the challenge to meet the pressure of chronic disease in developed countries has focussed on primary care. It was assumed that strong primary care was the most effective and efficient way to address the growing problem.
However, although excellent examples of primary care management of chronic conditions have been developed across the globe scaling them is proving challenging. Inadequate facilities, a short supply of health workers and a lack of knowledge about managing chronic conditions are hampering attempts to hold back the tide.
Even efforts to apply evidence-based interventions are proving a burden in the western world. In the UK, the gold standard for Type 2 diabetes training is DAFNE (Dose Adjustment for Normal Eating) a course that requires the at-risk individual to attend 13 one-hour courses over nine months.
Omada Health – Personalised digital behaviour change
Sean Duffy, the founder and CEO of Omada Health, wants to combine the best of evidence-based behavioural science with the best in design and technology. Omada want to identify what works and then translate it into digital therapeutic approaches designed to generate outcomes. The company’s first product, Prevent, is an online weight loss and lifestyle program for pre-diabetes. It is based on Diabetes Prevention Program (DPP) studies that showed that modest weight loss, the result of regular physical activity and a low fat, low calorie diet did delay or prevent progression to diabetes.
A company-run study, published in Diabetes Educator, documented the following results:
• Participants completed an average of 13.8 out of 16 lessons
• Body weight was recorded in 90% of the core sessions
• Participants lost five per cent of their body weight during the sessions and maintained this wait loss for 12 months
• Baseline blood sugar levels (HbA1c) regressed from the pre-diabetes range to the normal range
Overall, Prevent was found to have performed as well as residential versions of the course.
NHS England has recently commissioned a £100,000,000 five-year Diabetes Prevention Programme that aims to educate 100,000 people a year using DAFNE. That represents £200 a course. Not a huge price until the scale of the problem is understood. There are five million people thought to be at high risk of contracting Type 2 diabetes in England. The cost of applying this evidence-based approach to all of them would be £1bn5.
This is a notional cost because the evidence base suggests although the courses are effective most diabetics will decline to attend because the approach doesn’t fit their lifestyle or perception of themselves. The National Audit Office in the UK reported that only 16% of newly diagnosed diabetics were offered structured education and fewer than four per cent of those offered attended the courses 6.
The provision of healthcare is complex. There are many stakeholders, each with their own objectives, motivations and incentives. Improving health outcomes is as much about provider behaviour change as it is about patient behaviour change and requires buy-in from multiple stakeholders7.
Behaviour change is the marketing concept that has driven the digital consumer revolution over the last 20 years. Retailers and other service industries realised their customers were inherently complex and willing to try a variety of appropriate delivery mechanisms and increased personal involvement to gain quick low cost access to high quality services and products.
If we accept pre-service tasks and behaviour change in the realm of travel, shopping and banking, what would a similar concordat look like between patients and healthcare providers for such a service prior to or after entering primary care?
Dr Molly Coye, former Chief Information Officer for UCLA Health and current Social Entrepreneur in Residence at the Network for Excellence in Health Innovation, explained: “Most doctors think of healthcare in terms of patients coming to visit them and doing lab tests.
“At UCLA we had 250,000 primary care patients but what happened to support them before they came to see the doctor, and what might have prevented them from having to see the doctor? David Lawrence8, the former Chief Executive of Kaiser Permanente, and I began to call that pre-primary care.”
She added: “For physicians who trained 20 to 30 years ago it is hard to believe that patients want these services and they are uncomfortable with these new ways of working, but young doctors are right there, ready for it all (see the Patient.co.uk survey detail on p.16).
“David and I realised if something can be provided by technology it can be delivered by a lower level of healthcare worker or the patient themselves outside the traditional primary care environment. We felt patients and doctors would be more willing to accept these interventions if we could define a different function for the workers and the tools delivering the service.”
In Dr Coye’s vision, pre-primary care has no buildings. It is an interstitial market copying giants like: Amazon, a book seller without book shops; Uber, a taxi firm without cars; AirBnb, a hotel without rooms; Netflix, a cinema without theatres; Google, a content provider with no content and Skype, a phone company without phone lines.
In the same vein, the first truly global provider of pre-primary care will have few doctors and no hospitals. Instead they will have digital devices and tools used at scale in communities often supported by healthcare workers with lower level qualifications.
Far fetched? Twenty million people – a third of the UK population – look up health advice and information on NHS Choices (www.nhs.uk) every month. A trend that Google’s research department says is a global phenomenon. According to the search engine giant 70% of people now look up health symptoms online before going to see a doctor. And an Intel survey in 2013 found 70% of people would use a sensor in their toilet or bottles, 64% want a personalised healthcare regimen and 53% would trust the test they personally administered.
Dr Coye explained: “Primary care is defined as healthcare provided by a medical professional with whom a patient has initial contact, who coordinates their care, and by whom the patient may be referred to a specialist - but in the US a lot of people do not see a primary care provider all year.
“In India they have done a lot of work recruiting workers in the community whose job is to search out individuals and families who might be at risk but aren’t attending primary care. These workers are providing baseline checks, education, and leveraging technology and, where necessary, referring into primary care.”
Dr Coye sees a shift to the patient doing more for themselves as an important component in stimulating large scale behaviour change, and believes that the only way to meet the goal of millions of engaged patients is through technology.
Dr Jorgen Skavlan, a Norwegian specialist in family medicine with 30 years’ experience added: “I now, for the first time, see a shift and a potential for real change by introducing pre-primary care. Medical professionals can in the future focus more on those individuals who really need medical attention and with that increase quality, availability and cost control. I think my colleagues will see that this paradigm change will be advantageous for themselves, their patients and the society as a whole.“
The timing is also important for policy makers. Jeremy Hunt, the UK’s Secretary of State for Health, said: “New concepts like pre-primary care are important given the broad consensus on prevention and the need to improve quality of care just as demand rises from our ageing population. So this is the right discussion to have as we seek new approaches to building a genuinely 21st Century health service.”
The driving force behind a global digital pre-primary care service is the mobile phone. The past decade has seen the mobile phone emerge as one of the most exciting developments in global health. The rate at which mobile phone coverage and access has spread is unparalleled in the history of technology.
Today there are six billion mobile phone subscriptions – the majority in developing countries. Ninety-five per cent of the world is covered by basic voice and text access. India has already surpassed the US with more than 400 million smart phone subscriptions And Ericsson estimate there will be 6.3 billion smart phone subscriptions globally by 20219
The potential for the ubiquity and affordability of mobile technology to democratise healthcare excites pre-primary care entrepreneurs. The convergence of mobile networks with increasing bandwidth capacity for data, the proliferation of low-cost smart devices and cloud computing are opening up new opportunities to support the delivery of pre-primary healthcare
Dr Hersch explained: “The smart phone is shaping up to be the dominant computing platform and it’s not hard to imagine that developing countries will leapfrog the PC era in much the same way that mobile communications leapfrogged fixed land lines.”
At the same time, low-cost point-of-care diagnostic and measurement devices are transforming the capabilities of patients and healthcare workers. Phones can now take ECGs, measure your pulse and blood pressure.
Dr Coye added: “Patient reported data will be vital. Increasingly people will have health monitoring and communication equipment in their home or wear it as they go through their day – and doctors and nurses will become skilled in understanding which patients will benefit from such systems.”
Dr Eric Topol, the author of The Patient Will See You Now highlighted in a Wall Street Journal article10 that wearable sensor tools are now being developed that can: monitor your heart function, check the amount of fluid in your lungs, track your glucose levels, measure eye pressure (to help manage glaucoma), and capture your brain waves. He added: “Someday, socks and shoes might analyze the human gait to, for instance, tell a Parkinson’s patient whether his or her medications are working or tell a caregiver whether an elderly family member is unsteady and at risk of falling.”
In addition, Topol is certain that smart phone attachments will soon enable you to perform an array of routine lab tests via your phone at a fraction of the current cost. Blood electrolytes; liver, kidney and thyroid function; analysis of breath, sweat and urine—all could be checked with small fluid samples in little labs that plug directly into smart phones.
Meanwhile, nearly all sophisticated medical imaging devices are being miniaturised: hand-held ultrasound devices are already available and some medical schools have begun issuing them in the place of the old-school stethoscope. Hand-held MRI (magnetic resonance imaging) machines are not far behind, and engineers at UCLA have come up with a smart phone-sized device that can generate X-rays. Topol claims: “It won’t be long before you can take a smart phone X-ray selfie if you’re worried that you might have broken a bone.”
The decentralisation of healthcare through low-cost and highly portable point-of-care diagnostics has the potential to revolutionise current limitations in patient screening – a development that makes the prospect of the developing world jumping to a pre-primary care model possible and even more likely.
Technology not only opens up the potential of a new pre-primary care diagnostic relationship with medical providers driven by citizens but also the possibility to revolutionise specialities where patients do not necessarily benefit from face-to-face engagement.
Mental health is a leading cause of disability in the western world. The UK Faculty of Public Health estimated in 2009-10 that poor mental health cost England £105bn and the Organisation for Economic Co-operation and Development estimated in 2014 that 40% of all new disability claimants in England had mental health issues amounting to a £70bn drain on the economy.
BigWhiteWall – Patient-Guided Mental Health Management
Access to mental health provision is oversubscribed throughout the developed world. BigWhiteWall (BWW) was developed to provide immediate support for sufferers prior to and after face-to-face referrals. In a survey of BWW members, 46% reported sharing an issue or feelings on BWW for the first time and 70% of members from local health contracts reported that using BWW improved their wellbeing in at least one way. Other findings included:
•People taking BWW GuidedSupport courses for anxiety experienced an average reduction of 3.5 points on the GAD7 (anxiety) scale
• For people taking depression courses, the average reduction in the PHQ9 (depression) scale was 3.5 points
• BWW’s LiveTherapy service has consistently shown recovery rates above the average achieved by Improving Access to Psychological Therapies provision. Of people referred into BWW’s LiveTherapy programme by their GP, 57% were moving to recovery. The national average recovery rate is 45%, according to NHS statistics.
Smart phones can now quantify your state of mind by a composite of real-time data: tone and inflection of voice, facial expression, breathing pattern, heart rate, galvanic skin response, blood pressure, even the frequency and content of your emails and texts.
A recent study by Gale Lucas in the Journal of Computers in Human Behavior11 demonstrated that people are more willing to disclose their inner thoughts to a computer avatar or virtual psychiatrist than a real one. With machines working to quantify moods and even offer virtual counselling to help make up for our profound shortage of mental health professionals, we can glimpse a new pre-primary approach to improving mental health.
While the world is currently focusing on digitally giving citizens access via video, voice or messaging to doctors this trend is quickly abating as suppliers realise the solution does not solve the shortage of qualified health professionals. A telephone or a Skype conversation is more convenient for the patient but probably takes up the same amount of time in a doctor’s day leading to only marginal productivity gains when what is needed to save healthcare is an algorithmic productivity gain.
Bruce Wilcox, a Loebner Prize12 winner and chatbot expert said: “This transfer to digital pre-primary care must happen. Mostly people get sick at night or at weekends when doctors aren’t around. That’s when they need reassurance.
“We are at least five years away but apps like Your.MD will be able to diagnose as well as the average doctor by then and I know that because artificial intelligence systems like the IBM Watson programme are already better than a doctor in specialties like radiology and pathology.
“It is inevitable that these apps are going to get better. Once you start adding sensor technology and giving people the freedom to order tests themselves it is going to be difficult to see what the doctor is adding. The Star Trek tricorder is coming. Doctors know more and they can order a test and narrow down the possibilities but that is an arbitrary restriction. What we are in the process of developing is a digital Dr House.”
At the moment, one barrier to wider adoption, particularly in the western world, is the appetite for apps is not matched by the evidence of their impact on people’s health and their interactions with healthcare providers. There are mixed feelings about them among professionals. In a global survey of doctors, despite their own use of technology (see digital channels table below)13
• 41% agreed with the statement that mobile apps could be a ‘game-changer’ for improving health
• only 36% stated that they would recommend a mobile health app in future to their patients
To date, there has been a real focus on apps and devices to improve wellness – such as step and calorie counters – as well as those focused on a single disease. There has been less of a focus on tools for complex costly patients.
One interviewee said that developers shy away from apps for complex patients. David Blumenthal, president of the Commonwealth Fund, said in a recent Cello Health Insight report: “They’re too complicated, they’re too unappealing, the ROI [return on investment] is too unclear, the time to pay off is too long [and] they need to know too much about these patients in order to develop these applications.”
A systematic review into smart phone apps for the prevention, detection and management of cancer found that, while there are a ‘considerable number’ of apps available, the evidence for them is ‘lacking’ (Bender and others, 2013).
Devices such as Fitbit and smart phones collect a huge amount of data. Patient portals such as Patients Know Best allow patients to integrate these with their EHR (electronic health record), while companies like EMIS Health and Medelinked are able to access data stored in Apple’s Health app once the end user has consented to share it. However, generally speaking there are issues around uploading app data to EHRs and even more so in meaningfully interpreting the results.
Several interviewees in the Cello survey had mixed views on the potential of wearables and apps.
David Furniss, Vice President, Global Government and Health at BT said: “There is an overemphasis on the device that people are using to capture the information and not on what am I going to do with the information now I have captured it.” There also remain security concerns around the use of mobile technology, particularly in unregulated markets.
In 2015, the UK NHS Health Apps Library carried out a systematic assessment of 79 apps certified as clinically safe and trustworthy. It found that 89% transmitted information to online services and that 66% of apps sending identifying information over the internet did not use encryption14.
Dr Hersch admitted the evidence base for digital pre-primary care is slowly evolving but he still believes “the question is not ‘if’ technology can improve access but ‘how’”. Dr Hersch explained: “I envision a technology-assisted pre-primary care eco-system that can support in an integrated manner providers, frontline health workers and patients.”
For Dr Coye the answer is rapid testing cycles: “Where a clinician is doubtful we should be doing a fast six-month test. Pull in the data and then discuss it. This will not answer every doctor’s doubts but it will grow the evidence base. But the strongest evidence over time is doctors saying this really works.”
What is likely to delay the introduction of pre-primary care systems longer than evidential and cultural resistance is money.
Who pays is a central question. Most systems segregate payments for services between primary, secondary and emergency care. Prevention and pre-emptive assessment are not new concepts but governments are reluctant to fund schemes.
Dr Coye explained: “The demand for primary care is such that general practitioners have nothing to fear. Their rice bowl won’t be broken because the demographic is too large. But the money to pay for pre-primary care has to come out of someone’s pocket.
“The evidence is that technology enabled care management can rapidly improve clinical effectiveness and reduce the total cost of care. And there are creative deals to be done. I can see a future where a health system pays a Type 2 diabetic patient $2,000 a year to diet and exercise in order to recoup $3,000 from a health insurer that would have otherwise paid $12,000 dollars in hospital and emergency room charges - and you would have a much healthier individual.” A recent McKinsey report ehealth 2.015 looked at four potential options for payment:
• User payment
• Free in return for data
• Health system payment
• Outcome-based payment
The report concluded that asking users to pay could restrict the market to those willing to pay - a segment that is unlikely to include those who would benefit most. Providing digital services in return for data raises privacy concerns and other data-sharing issues. Where data sharing works the patient is usually making a contribution to research e.g. patientslikeme or Flatiron Health. Payment by healthcare systems via “prescriptions” is an option preferred by developers but only makes sense in developed countries if the application can deliver measureable outcomes. In developing countries, payment by healthcare systems is also unlikely unless there is clear evidence of improved health outcomes to warrant the shifting of budgets. If “cash releasing” savings can be identified then outcome or value-based reimbursement models become sustainable both for the payor and developers. Payors are more likely to embrace enabling technology if their risk is diminished.
Trond Riiber Knudsen, former McKinsey Global Senior Partner and now chairman and CEO of TRK Group, the Oslo-based investment and advisory firm focused on disruptive technology, said: “Smart and high quality AI driven digital health platforms, broadly accessible to the world’s growing population, will be key to a more effective healthcare model in the years ahead - contributing to solving three fundamental challenges:
By attacking these issues early in the patient journey, these platforms will create a whole new market space - the pre-primary care market.“
In the West, pre-primary care technology will emerge as access pressures on primary care become so acute no doctor can ignore the case for change. In developing countries there is a clear need for an eco-system to be developed to plug the gap where no primary care exists or is ever likely to exist.
The World Health Organization (WHO) estimates there is a global workforce shortage of four million healthcare workers16. For developing countries this is further exacerbated by the “brain drain” that has seen an exodus of doctors and nurses to developed countries. The situation is particularly bleak in rural areas where critical workforce shortages can mean one doctor for tens of thousands of people.
The net result is that anywhere between million and billion people cannot get access to healthcare (see graphic below). For decades now the world has recognised that the quality of primary care directly relates to life expectancy
The World Bank Group, the WHO and the Bill and Melinda Gates Foundation “conservatively” estimate 400 million people on the planet do not have access to basic services usually provided by primary care.
All too often, primary healthcare is a weak link in health systems. The recent outbreak of Ebola, a disease that can be prevented through basic health measures, both exacerbated and was partially fuelled by broken or non-existent primary healthcare systems.
A Gates Foundation report also found that across 37 countries 6% of the world’s population was tipped or pushed further into extreme poverty (<$1.25/day) because they had to pay for health services out of their own pockets. When the study factored in a poverty measure of <$2/day, 17% of people in these countries were impoverished, or further impoverished, by health expenses.
Dr. Kaushik Basu, Senior Vice President and Chief Economist at the World Bank Group, commenting on the report17 said: “These high levels of impoverishment, which happen when poor people have to pay out of pocket for their own emergency healthcare, pose a major threat to the goal of eliminating extreme poverty. As we transition to a post-2015 development era, we must act on these findings, or the world’s poor risk being left behind.”
The WHO and the World Bank Group recommend that countries pursuing universal health coverage should aim to achieve a minimum of 80% population coverage for essential health services, and that everyone everywhere should be protected from catastrophic and impoverishing health payments.
Dr Hersch, explained: “In the West we latch onto primary care because it is the first line but the reality for the majority of the world is that primary care doesn’t exist. In Bangladesh where I work, you are lucky if you have three doctors for 10,000 people. The WHO classes anything below one to 1,000 as an unsafe system. The further out you go into the rural community the less primary healthcare you get. Access is a huge issue and the solution isn’t to train more doctors.”
He added: “This idea of defining pre-primary care in the global context is about empowering people to address a market failure, democratising healthcare, giving power back to people and demystifying healthcare for the consumer.
“How can we leverage digital technology to link people and support them through a journey? It doesn’t all have to be digital, it could be a technology-enabled healthcare worker in the community.
“Yes, there are certain things you need a doctor for but all sides have to be reasonable about this. We’re not diagnosing cancer with an app but we could be stopping the spread of non-communicable diseases by efficiently disseminating information. We sometimes over medicalise the medicine when what we are talking about is promoting health.
As a doctor I’m not trying to get rid of myself but I think we’ve forgotten that medicine is an art as much as a science. We’ve buried the art by trying to deliver more care, when what is needed is time for better quality of care. If doctors are pressured for time you cannot expect them to deliver holistic ‘patient-centered’ care. If we can unload pressure in the system and bring in tools to make the workload more manageable then doctors will return to being caregivers rather than reactionary decision makers.”
Dr Hersch added: “If you understand the health risks of a population (through access to good data) then you can begin to intervene more strategically and offer the right “digital therapeutics” at the right time to activate them and begin the (difficult) process of behaviour change.”
Several countries offer examples of high-performing primary healthcare. Brazil’s efforts to train and assign primary healthcare workers to specific neighbourhoods have led to dramatic gains in health, especially in the country’s poorest areas. Ghana’s efforts to implement mobile-based primary healthcare have helped the country achieve reduced infant mortality and increased life expectancy.
“The demand for primary care is such that general practitioners have nothing to fear. Their rice bowl won’t be broken, the demographic is too large.”

In the developed world we have misplaced our self-reliance and our health systems are suffering as generations fail to maintain their bodies or attempt to care for themselves. This over reliance on the medical establishment is estimated to cost the NHS £2bn a year.
In 200718 a study of the medical records of 130 UK general practices over a two-year period found 51m - 90% of the consultations - were for minor ailments and 88% of those were suitable for self-care.
WebGP – Patient Triage
Hurley Group, a London-based GP organisation, has developed a patient self-triage system. On entering the site consumers can either make a face-to-face appointment in several days’ time or fill out one of 100 digital forms that relate to the condition they want to discuss. That form triggers a phone call to the patient either from a nurse or GP within 24 hours (some surgeries call back within an hour). The system was developed after Dr Arvind Madan looked at the Hurley Group’s patient data and realised most people had minor ailments, knew what was wrong with them mostly knew what to do but were seeking reassurance. An analysis of a pilot study of WebGP over six months found that:
• of the e-consults, 40% led to a prescription, 40% led to a GP appointment and 20% led to a telephone consultation
• 18% of patients self-managed an issue for which they had planned to see a GP
• for every WebGP user requiring a GP response via an e-consult, five users required online self-help only (WebGP, 2014).
Even more surprising was that 75% of all the consultations were about ten specific minor ailments: back pain; dermatitis; heartburn; nasal congestion; constipation; migraine; cough; acne; sprain and headache.
All these ailments were considered to be suitable either for a pharmacy visit or self-care but in a staggering 90% of the consultations for minor ailments patients received prescriptions worth £371m when they could have bought cheaper over-the-counter medicine.
In total, the study found that 20% of a GP’s time was being spent on minor ailments that could have been treated by a pharmacist or an individual at home with better information and pre-primary care support. Further studies suggest that between 15% and 40% of all A&E visits are for minor ailments and injuries that could have been treated at home.
In 2004, the European Self-Medication Industry Association (AESGP)19 carried out a detailed economic analysis of a move from prescribed medicines to self-medication in the UK. It concluded that the change would free up an average time of eight minutes per consultation. Time freed up as a result of the lower number of doctor visits for minor ailments represented 2.8 million doctor working hours per annum or 21 hours per doctor per year.
Research carried out by the Proprietary Association of Great Britain (PAGB) and IMS Health suggests that a focus on pre-primary care could reduce GP visits by 40%; outpatient visits by 17%; A&E visits by 50% and hospital admissions by 50%. In addition, two thirds of GP prescriptions could be transferred to cheaper over-the-counter drugs or no medicine at all.
Nicolas Roope, founder of Poke and acclaimed digital designer and entrepreneur, said: “In the NHS the conversation is about money against a seemingly fixed cost resource of doctors, practices, hospitals, beds and drugs. If you want more service, less waiting, you have to pump in more money. Attempts at efficiency gains through management restructuring have turned into a running joke in Whitehall and across the media. There seems to be no way out of this quagmire. But there is a way.
“If we could take a huge chunk of the informational quotient of doctors’ time and replace it with more distributed, more accurate, free service for everyone, doctors would be left to focus on what they really need to be there for. This would allow a refocusing of time and resources that would immediately result in more rapid and accurate solutions and much lower waiting times for those still requiring attention.
“The frontline of primary care that takes up 20% of doctors’ time can be largely improved, sped up and replaced by technology like artificial intelligence. Less cost and less burden on public healthcare, and more focus and attention on when a doctor needs to be in the same room as the patient to resolve the problem.
“Conversational artificial intelligence personalises responses from the very first question, carving up millions of diagnoses rapidly towards the result that is right and accurate for you.”
“Technology like Your.MD is not a challenge to the medical profession. On the contrary, it’s an adrenaline shot to its arm. Seventy per cent of doctors in the UK report they don’t have time to do their job20. For some time patients have gotten used to their doctors looking up symptoms on their PCs, which leaves many wondering why the medical profession hasn’t followed banking and many other services and cut the need for physical premises, with costly physical professionals, enabling what everyone now knows to be standard procedures in smart phone-app-land.”
Jim Dawton, Director of Impeller Ventures and former Lead Specialist Designer at the Technology Strategy Board, described the challenge more prosaically.
“Primary care is like the shed at the bottom of my garden. I’ve put so much stuff in it over the years I now can’t find the space inside to reorganise it. The only approach is to put another shed alongside it and take out the stuff that doesn’t need to be in the first shed anymore.”
Impeller Ventures believes the solution can be found in pre-primary care. The diagram on p36 is based on its Wellness and Wholeness model of care and has been modified to show the practical interventions at each level.
MyDirectives – Patient Voice
Driven by their grandparents’ traumatic end-of-life experiences, MyDirectives’ founders Scott Brown and Jeff Zucker from Dallas, USA have developed a multimedia approach that demedicalises, standardises and demystifies the process of describing your preferences, values and goals in the event of a health crisis. Available 24/7 anywhere in the world it frees clinicians from the burden of sitting down and recording patients’ decisions and statements and makes it easy for doctors to retrieve a patient’s statements anywhere in the world. Coordinate Care Oklahoma (CCO) has now invited more than one million of its 4.2m users in five states to create a MyDirectives’ profile. The directives created can now be accessed in 45 hospitals in the CCO family.

Bill Gates, the founder of Microsoft, predicted: “As more people obtain access to better and cheaper digital technology, an inflection point is eventually reached, at which the benefits of providing digital services like banking and healthcare clearly outweigh the costs.”
Imagine community health workers in the developing world armed with care protocols, low-cost diagnostics and mobile phones with artificial intelligence-driven decision support software.
An army of individuals with the ability to provide care, including advice and treatments, for a range of common conditions, minor ailments and injuries and information about prevention and behaviour change digital therapeutics. Pre-primary care driven by artificial intelligence, natural language programming, high quality content and early intervention. People diagnosing themselves and ordering tests then using doctors to help them interpret the results.
To meet existing and future health challenges we will require increasing investment in pre-primary healthcare driven by digital technology. Healthcare systems will need to do more for less by deploying their biggest assets - patients doing more of the heavy lifting for the service.
As technology transforms it will increasingly be able to meet local needs and deliver multiple approaches that fit individual’s lifestyles and needs. Truly personalised healthcare at scale.
Soon we will see a global health brand based on the provision of trusted pre-primary care. As Dr Topol said in the Wall Street Journal: “Just as the printing press democratized information, the medicalized smart phone will democratize healthcare. Anywhere you can get a mobile signal, you’ll have new ways to practise data-driven medicine. Patients won’t just be empowered; they’ll be emancipated.”
Dr Coye concluded: “Primary care physicians will be more accepting of pre-primary care if they understand that valuable clinical and psychosocial services can be accomplished by technology-enabled health workers and by patients themselves, and that this will reduce the physicians’ workload, improve clinical outcomes and reduce the total cost of care.”
Pre-primary care is the solution – and it is here today.
Doctors know more and they can order a test and narrow down the possibilities but that is an arbitrary restriction. What we are in the process of developing is a digital Dr House.”
