Is machine learning the new buzzword for healthcare?
By now, it’s old news that big data will transform healthcare. Electronic health records and health information systems have arrived, data flows, and there’s a lot of it. However, all this data, is only useful when it has been analyzed, interpreted and acted on. So will it be algorithms that perform this analysis that will really transform healthcare?
Access to lab results via a mobile app, has helped clinicians diagnose and treat patients faster. Imagine how much more useful these results would be if they also showed the patient’s risk for cardiovascular disease or renal failure, based on the last several years of the patient’s lab reports. This is where machine learning might help physicians to make better decisions at point of patient care.
Machine learning is an area of artificial intelligence (AI) that is starting to attract interest in healthcare. It is a set of algorithms that help a system to automatically learn and predict outcomes, after continuous exposure to variable datasets. The value of machine learning in healthcare is its ability to process huge amounts of clinical information, beyond that of human capability, and then reliably convert analysis of that data into clinical insights. This will help physicians plan better and ultimately lead to better outcomes, lower costs of care and increased patient satisfaction.
Machine learning is already making headlines in healthcare. Google has developed a machine learning algorithm to help identify cancerous tumors on mammograms. Stanford is using a machine learning algorithm to identify skin cancer. A JAMA article, last year, reported the results of a deep machine-learning algorithm that was able to diagnose diabetic retinopathy in retinal images. Others, like Philips, are transforming TB screening, using machine learning algorithms that can offer an objective opinion to improve efficiency, reliability, and accuracy.
Machine learning puts a new arrow in the quiver of clinical decision-making.

EU’s BigData@Heart aims to improve heart disease treatments
A report on Cardiovascular Disease (CVD) published by Springer says CVD prevalence in sub-Saharan Africa’s increasing. Limited access to prevention and continuing care are seen as constraints to improvements. The EU’s BigData@Heart project may contribute to the development of treatments for heart disease patients. It has lessons for Africa’s health systems.
It’s a large-scale, five-year, €19 million project. Its aim’s to use data and advanced analytics to develop a translational research platform of phenotypical resolution to improve patient outcomes and reduce societal burdens of atrial fibrillation (AF), heart failure (HF) and acute coronary syndrome (ACS). Data sources include real-world evidence, best-practices in drug development and personalised medicines.
Four outputs are:
· New universal, computable, definitions of diseases and outcomes relevant for patients, clinicians, industry and regulators
· Informatics platforms linking, visualising and harmonising data sources, completeness and structures
· Data science techniques to develop new definitions of disease, identify new phenotypes, and construct personalised predictive models
· Guidelines that allow for cross-border use of big data sources acknowledging ethical and legal constraints and data security.
It can have considerable value for Africa. The continents health systems and cardiologists could move their CVD services ahead in the wake of BigData@Heart’s progress.

Africa’s eHealth isn’t far behind South America and Mexico
Africa’s eHealth has a different profile to the average for South America and Mexico, but it’s not trailing significantly. Comparing findings from the WHO and GEO’s Global eHealth Survey 2015 shows similar simple coverage rates of just over a third. A global average’s near 50%.
Perhaps the most important difference’s the emphasis on Big Data. South America and Mexico are at about 12%. Africa’s at about 2%. The survey didn’t ask for data about Artificial Intelligence (AI) or coverage of cyber-security. It doesn’t provide data about the quality, sophistication or maturity of the coverage. It’s not easy data to assemble, quantify or analyse.
Suffice to say, it highlights the need for Africa’s health systems to catch up on AI. A first step may be using their existing data more extensively. A second may be supporting public health specialists and clinical teams in local AI initiatives. The comparison seems to indicate no need for a sudden rush. A steady, imaginative plod along the AI road should be sufficient.

AI and Big Data will transform healthcare
There’s a substantial progression of digital capacity in which data is produced and stored. In 2013, the amount of available digital data encompassed 4.4 zettabytes and it is estimated to reach 44 zettabytes, which is 44 trillion gigabytes, or ten times more by 2020. There is no denying that the world of Big Data’s enormous. Healthcare’s challenge is how to make best use of it.
Artificial intelligence (AI) is a vital and increasing part of it. It’s quickly becoming a necessity for healthcare. AI’s already widely used in everyday life. It’s in cars, Google searches, Amazon suggestions and other devices, but is yet to extend towards large-scale, routine AI for sophisticated activities such as healthcare and its clinical decisions.
AI services such as Apple’s Siri, Microsoft’s Cortana, Google’s OK Google, and Amazon’s Echo can extract questions from speech using natural-language processing and perform limited set of useful things, such as looking for restaurants, provide directions, find an open slot for a meeting, or run a simple web search. In addition, a 19-year-old British programmer launched a bot last September which is successfully helping people to appeal their parking tickets. It’s an “AI lawyer” that sorts received parking tickets. In both London and New York, the bot has a success rate of 64%, which translate to 160,000 of 250,000 parking tickets successfully appealed.
The same efficiency is essential in healthcare. An article in Medical Futurist reports that in years to come, AI in healthcare and medicine may organise patient pathways and treatment plans, and provide doctors with all information they need to make better informed decision. Several companies have a stake in AI in healthcare. They include Dell, Hewlett-Packard, Apple, Hitachi Data Systems, Luminoso, Alchemy API, Digital Reasoning, Highspot, Lumiata, Sentient Technologies, Enterra, IPSoft and Next IT. Their ultimate goal is to transform medicine and healthcare in way that ensures that it’s widely available to the average, mainstream users and not only the richest medial institutions or to a handful of experts.
AI’s used in several areas in healthcare. It includes mining medical records, designing of medical plans and medication management. Googles AI research branch in cooperation with the Moorfields Eye Hospital NHS Foundation Trust in London has launched a Google Deepmind Health project. It mines medical records to help to provide better and faster health services.
This year, a British subscription, online medical consultation and health service launched Babylon. It offers medical AI consultation based on personal medical history and common medical knowledge. Users report the symptoms of their illness to the app, which checks them against a database of diseases using speech recognition. After taking into account the patients’ histories and circumstances, Babylon offers appropriate courses of action. The app also reminds patients to take their medication and finds out how they’re feeling.
Molly was the first virtual nurse developed by Sense.ly, a medical start-up. It aims to help people to monitor their condition and treatment. Nurses use machine learning to support patients with chronic conditions in-between doctor’s visits. Customised monitoring and follow-up care is part of its service too, with a strong focus on chronic diseases.
The AiCure app maintained by The National Institutes of Health monitors patients’ medication compliance. It uses a smartphone’s webcam and AI to confirm patients’ medication ingestion and helps them to manage their conditions.
AI still has a long way to go. It will be exciting to see how Africa’s health systems adopt it in their eHealth strategies and use it to transform health and healthcare.

eHealth, Google and others are revolutionising healthcare in emerging markets
Access to basic healthcare information is a challenge in many parts of the world. It’s especially demanding in developing countries. Google’s latest move in India may help increase access to healthcare information for millions of people.
An article in The Market Mogul says Google identified this gap in Indian and has added health information to its Knowledge Graph. It’s a sematic search base that Google uses to supplement organic search results with summarised information.
So, the next time someone in India uses Google to search common health conditions, it’ll show information cards illustrated with images. This information will include typical symptoms, details on how common the condition is, whether it’s critical, if it’s contagious and which age groups it affects. Google said that it’ll provide a condensed version if users have limited Internet connections. This goes some way to deal with India’s slow and intermittent mobile connections.
An article in TechCrunch says Google’s initiative is in response to start-ups dedicated to democratising India’s healthcare. Lybrate, an online, web-based healthcare service’s an example. It aims to increase access to doctors and quality healthcare information. It’s app service allows users to ask doctors questions online, search surgeries nearby and make and manage appointments.
Other developing countries benefit from mHealth initiatives too. Successful start-ups include Docway, Beep Health and Dr Vem! in Brazil. These use apps and the web to connect patients and doctors. Doctors have to be registered with the app, and set their own consultation rates. Users can also browse doctor’s resumes before deciding to book appointments. Most users are parents looking for paediatricians. The next big group of users are elderly people with limited mobility.
Are these online initiatives coming to Africa on a big scale? A more appropriate question may be when will they be available?

Big Data is not big in Africa’s eHealth - unpacking the 3rd Global Survey on eHealth
As a relatively new part of eHealth, Big Data has a negligible effect on Africa’s health systems and eHealth programmes. Big Data insights are in Chapter 8 of the WHO and Global Observatory for eHealth (GOe) publication eHealth Report of the third global survey on eHealth Global diffusion of eHealth: Making universal health coverage achievable. WHO Global Survey 2015 provides the data source for the report.
It hasn’t taken off globally yet. Fewer than a fifth of countries say they have a national policy or strategy for regulating Big Data in health and healthcare. In Africa, it’s about 2%. This Big Data deficit isn’t much of a cause for concern. As the eHNA posts about WHO’s report show, Africa’s health systems have many other eHealth priorities. One that wasn’t included in WHO’s survey is stepping up cyber-security. Acfee’s report from its African eHealth Forum (AeF) our priorities include cyber-security and others, such as Interoperability (IOp), cloud computing, eHealth governance, regulation and capacity building are well ahead of Big Data.
WHO found that a lack of integration, privacy and security are major barriers to Big Data adoption. It’s constructive that Africa’s health systems are focusing on these as part of their expanded eHealth initiatives. Acfee’s activities in 2017 will support them.

Big Data needs analytics tools and skills
Africa’s not yet investing much in Big Data compared to the global trend. It’s revealed in the WHO Global eHealth Survey 2015. An article in Healthcare Informatics, by Joe Mario, founder of Healthcare Integration Strategies, sets out two requirements for success that Africa’s health systems should adopt:
- Capture useful data in the proper format needed
- Have the analytic tools needed to extract meaningful information.
He also implies that healthcare organisation’s need to set up a data mining unit. He could’ve added a fourth requirement, having people with the analytic skills to design and run the data capture and use the analytic tools effectively. All four Big Data components are in short supply across Africa.
He sets out two organisational options. One is a centralised Big Data unit of analytic specialists supporting healthcare teams. The other’s decentralised, where each healthcare provider has its own team. For Africa, a decentralised model seems unrealistic until enough analytic specialists are available and affordable.
Setting up a centralised model needs a long-term plan to recruit, develop and retain analytic specialists. Success depends on health ministries working closely with universities to ensure a steady stream to build up a steady stream of health analytics specialists. The pace and scale needs to match the equivalent endeavour for health informatics specialists and the availability of data sources such as EHRs.
There are many other competing demands for these eHealth resources and tight affordability constraints. These combine to create a scenario where Africa’s Big Data programmes are likely to be relatively small, highly focused and provided by small, centralised teams. A big step forward’s including something like this in the next round of eHealth strategies.

Big Data's transforming health and healthcare
Africa’s health systems will always need to adopt modern eHealth for disease surveillance, especially epidemics like Ebola and Zika. The recent WHO eHealth survey reported in eHNA found that Africa’s health systems are well behind in their Big Data and analytics strategies. Most countries have no Big Data strategy. A report on the Information Age shows why they have to catch up.
It says intelligent uses of Big Data in healthcare are helping to predict epidemics, find cures for disease, improve quality of life and avoid preventable deaths. These are big impacts, and even more important as Africa’s population increases and ages. Big Data can help to develop new and changing models of healthcare treatment and delivery.
Big Data blood supply, its data, is expanding rapidly. More data’s been created in the last two years than in the entire previous history of the human race. It’s not stopping. By 2020, about 1.7 megabytes of new information will be created every second for every person on the planet. By then, data’s accumulated digital universe will’ve grown from 4.4 zettabytes today to around 44 zettabytes, or 44 trillion gigabytes, a ten-fold increase in just four years.
Whether it’s the megas, zettas or trillios is less important than adopting, developing and using Big Data for its benefits. Understanding more about individual patients as early in their life as possible offers opportunities to find warning signs of serious illness early enough so treatments can be easier, simpler, cheaper and more successful than later diagnoses.
Big Data’s not a simple solution. It has several challenges. Storing and managing needs big archives to preserve large volumes of data for future research. Security and compliance challenges run alongside this. Ben Rossi, the article’s author suggests that pathology services offer a good way for healthcare organisations to deal with this.
Pathology services are regularly adopting new digital technologies that offer new Big Data opportunities. eHealth’s helping pathology labs to benefit from digital workflows that foster innovation that can transform patient care. A modest pathology lab with one small slide scanner will generate over 15 terabytes of data a year.
It could be a way into Big Data for some African health systems. When will all African countries start on Big Data?

Analytics can help with medication compliance
Once patients are back home, complying with medication regimes seems an continuing intractable challenge for many of them. SMSs have played a valuable role. Now, analytics has emerged on the scene.
A report in Health Analytics says Sanofi has partnered with Duke Clinical Research Institute (DCRI), Massachusetts General Hospital and its Center for Assessment Technology and Continuous Health (CATCH) to improve medication adherence rates for Type 2 diabetes patients. The team’ll use Big Data analytics tools developed by DCRI and CATCH.
Using all available data, including demonstrated behaviour, is seen as an innovation to direct personalised care and engagement programmes and practical tools and services so people with diabetes can engage more proactively with their treatment. Better outcomes are the planned benefits. They’ll be achieved by healthcare provider anticipating medication adherence rates for individual patients, then intervening as needed with appropriate actions.
The project’s part of a trend. Medical researchers are relying increasingly on predictive analytics to improve chronic disease management, especially medication compliance. Failure to comply has a high costs. In the USA, it’s estimated that it cost the healthcare industry approximately US$337b in 2013. It’s also associated with unsatisfactory population health management programmes.
A data challenge’s that healthcare providers are reluctant to integrate data about medication adherence into EHRs, mainly due to data overload. There’s also some dissatisfaction with value of patients’ data from pharmacies and health insurers.
A solution’s seen as semantic data analytics tools. Healthcare providers and Big Data scientists are relying more on semantic databases for comprehensive insights on population health management. They draw from different data sets, such as patient information, socio-economic data and pharmacy information to produce more accurate and reliable predictions about patients’ outcomes. These are from connections of different concepts rather than displayed rows of specific information.
As US healthcare strives to move Big Data ahead, Africa’s health systems can begin to develop their Big Data strategies. WHO’s latest eHealth survey, reported on eHNA, showed a marked lack of progress.

How can Africa catch up with Big Data?
Big Data offers big promises. Even if it’s not true, Big Data does offer new opportunities. eHNA has reported that WHO’s 2015 eHealth Survey found that out of 33 African countries, only one’s started to deal with Big Data.
IBM Watson has released its white paper Social and behavioural determinants of health A look at fundamental drivers of health and disease to help improve population health and reduce costs. It has valuable constructs that can help Africa’s health systems build their Big Data and analytics strategies, plans and services.
It proposes a shift in the approach to Population Health Management (PHM) from a context of patient populations to communities where people live, work and play. Many factors comprising Social Determinants of Health (SDH), such as employment, healthy food and people’s physical environment are beyond doctors’ and hospital’s control, but healthcare organisations can work with communities to help patients deal with SDH factors that affect their health and access to healthcare. A current limitation to progress is knowing how to do it.
The white paper explains:
- What SDHs are
- How they influence people’s health
- What healthcare organisations can do to improve population health
- How behavioural health affects physical health
- Why it should be integrated with primary care
- A new concept of service delivery integrating healthcare with social services
- The kind of eHealth needed to support these.
Five are set out as:
- Model 1: targeting health behaviours where doctors and healthcare teams try to induce
- patients to modify their health behaviour
- Model 2: referral to community services, especially community health centres care for people o lower incomes
- Model 3: limited social support in healthcare frameworks
- Model 4: patient-centred medical homes that emphasise SDH
- Model 5: holistic care management that integrates healthcare and social services.
Advantages of integrating healthcare and social care
It’s shown to produce measurable benefits. They include:
- Twice as effective at treating depression
- Improves physical and social functioning and quality of life
- When behavioural health is engaged, healthcare organisations seeking to address SDH must work with social services and other community resources
- Reduces overall healthcare costs.
An integrated service needs a wider range of information than segmented services. This’s where Big Data’s needed. The range of sources is considerable, and includes:
- Social services adult and child teams
- Functional assessment surveys, even though they’re currently uncommon in mainstream healthcare
- Health insurance databases
- EHRs and administrative systems
- Places of residence
- Administrative records
- Distances to nearest clinics, health centres and food stores from geographical information systems
- Living situations, such as living alone, from social service agencies and public records
- Physical disabilities, from EHRs and disability insurance records
- Employment status from unemployment insurance and social security records
- Environmental hazards, such as poor housing from building reports
- Air quality from weather reports
- Diet and exercise from health risk assessments
- Medication compliance, from prescription records and mHealth reminders.
As African countries are still at the Big Data starting gate, planning to achieve all these isn’t realistic. A more modest approach’s needed to make a start, and communities with potentially high levels of SDH or poor access to healthcare may offer the best returns. These could be urban populations living in poor housing and remote rural communities. From a small start, Africa’s health systems and can learn and grow their Big Data skills, priorities and benefits.
