Remote care: is digital health tech here to stay post-COVID-19?

Digital technology has been poised to transform the way that healthcare is delivered. Yet uptake and implementation has been slow; in the UK alone for example, almost a quarter of hospitals still use paper rather than electronic records.

But when COVID-19 hit, health systems were forced to rapidly adapt and use technology to deliver care remotely, where face to face appointments were no longer possible. While it’s impossible to predict when the COVID crisis will be over, will remote care become the ‘new normal’ post-pandemic? And if digital-first health technologies are here to stay, what are the implications for patients?

Newly launched IGHI research, supported by Imperial’s COVID-19 Response Fund, will explore these important questions. We caught up with project lead, IGHI Research Fellow Dr Ana Luisa Neves, to find out more about the work and what it hopes to achieve.

What are digital-first health technologies?

“These are all means in which the patient’s first point of contact is through a digital channel, rather than face-to-face. For example, phone and video consultations, online services, and mobile apps.”

Why are you interested in these?

“Our idea is that digital technology can help tackle challenges that we had before COVID hit. Like making care more accessible and affordable, and reaching groups of people who may not be confident going to a doctor or nurse.

“Right now we’re in the middle of a massive real-life experiment, which has pushed this closer to reality. We will resume normality at some stage, however it may look. But what can we take from this experience so that we can continue using these models in a better way?”

What are you hoping to find out about these technologies?

“We want to understand the patient experience. In principle these technologies should improve accessibility, but that may not turn out to be true – or at least not true for everyone. So we’ll explore the potential barriers to healthcare access, whether some individuals or groups are somehow excluded from these technologies.

“We also want to look at patients’ attitudes and perceptions. In what circumstances do they want to use digital technologies? How do patients want these to move forward? When do they think that digital tech may work better than more traditional models of care, and how can we create conditions for that to happen?”

And how are you going to answer those questions?

“This work sits within a broader program of work that’s also looking at GPs’ views of these technologies. That’s using a global survey and focus groups, involving 18 countries. We’ll be replicating this method but looking at patients’ perspectives instead.

“We want to make sure we get nationally-representative samples from countries and information about demographics, as well as ‘digital literacy’. Part of digital literacy covers technical aspects, such as Internet access, but also individuals’ ability and experience using digital tools.”

Do you have any assumptions about what you might find?

“I expect we’ll find that certain groups feel excluded. Evidence has shown that elderly individuals, for example, or those with lower digital literacy are less likely to use these technologies. We want to understand what we can do to make it easier for them.”

How will you apply your findings to healthcare settings?

“We’re hoping to bring together the findings from both GPs and patients, and then consider how we can make these technologies better for the future. We’ll then develop a framework for recommendations, a ‘toolkit’ that healthcare professionals can use to support decision-making. For example, when triaging patients, the framework could help doctors identify when digital technologies may be useful and appropriate. This could help doctors decide whether to offer digital solutions as part of patient care, post-COVID-19.”

Older people are no more COVID cautious

Elderly people crossing the road during COVID-19

Grappling with a novel virus that reared its ugly head barely six months ago, the world is facing many uncertainties. The SARS-CoV-2 virus is proving unpredictable and the pandemic is fast-moving. But one thing we do know is that older people bear the brunt of the impacts of COVID-19. The elderly are disproportionately affected, with those over 65 accounting for some 80% of hospitalisations due to the disease. And one in five over-80s with COVID-19 will need to go to hospital, compared with one in 100 individuals under 30. (more…)

What’s it like to… work with wearable sensors?

By Dr Benny Lo, Senior Lecturer, MRes Medical Robotics and Image-Guide Intervention,
Hamlyn Centre, Institute of Global Health Innovation

I started my research on wearable sensors when I was appointed as a researcher in a UK Trade & Investment (now Innovate UK) funded project, while I was working on my PhD on a completely different topic.

When I first started working on sensor research, the concept of wireless sensor networks had just been introduced. I was one of the first few researchers who started the development of body-worn sensors for healthcare and wellbeing applications. Being one of the pioneers in this emerging field, I have developed a number of novel sensing platforms, and some have been widely used in the research community.

In wearable sensing research, we often have to start from scratch. We build our own sensing hardware, compose the embedded software, design the networking infrastructure, and develop the data analysis algorithms, as well as conducting the clinical validation studies. Basically, we have to start from generating the new ideas, turning the ideas into working prototypes, and then carry out the studies to evaluate the technologies’ potential benefits to patients. Although it is very challenging, I have learnt and gained invaluable experience in multi-disciplinary research. Apart from addressing healthcare challenges in the UK, our work has been extended to address some global health challenges.

Currently, I am leading a Bill & Melinda Gates Foundation funded project with a team of researchers from the UK and US to develop wearable and AI technologies to enable accurate assessment of dietary intake. The project aims to develop the technology to support large-scale nutritional studies, in particular assessing family nutritional intakes in low- and middle-income countries.

We plan to deploy and trial our technologies in rural and urban households in African countries. It is a very ambitious and challenging project, but at the same time,

it has given us an opportunity to develop technologies which could potentially transform the field of dietary intake analysis.

While tackling the challenges in conducting field studies in Africa, my research group is also working closely with a research partner in Thailand. This project is deploying and testing our low-cost wearable sensors for fall preventions in local hospitals and residential care homes. Apart from healthcare applications, I have also explored the applications of sensing technologies for elite sport training and other applications.

With the advances in 5G mobile networks and Internet of Things (IoT) technologies, we anticipated that sensors will be widely used in supporting the digital transformation of our society. In particular with the current COVID-19 crisis, pervasive and low-cost sensing technologies could help alleviate the pressure on our healthcare services while providing quality care remotely.

As I started my research in this new field at its infancy, it has been a very exciting journey. It has given me opportunities to investigate novel technologies to tackle major healthcare challenges. The most rewarding part of my work is seeing our technologies being deployed and used to help patients.

Breaking habits: swapping sugary drinks for healthier alternatives

Excess sugar consumption has been a critical public health matter for some years.

Too much sugar in our diet can contribute to health problems such as obesity and diabetes. Large amounts of sugar are often found in soft drinks such as fizzy drinks and fruit juices, as well as many of the foods we commonly eat, from cereals to sauces. For instance, just one can of cola can contain nearly nine teaspoons of sugar when our recommended sugar intake shouldn’t exceed 5-6 teaspoons per day.

Please indicate whether your research will include patient and public involvement.” Ticks box.

Rapidly fading are the days when involving patients and the public in research is merely a tokenistic gesture, in favour of meaningful involvement and co-production.

Patient and public involvement (PPI) is research that’s carried out with and by patients, carers and public members, rather than to, for or about them. Co-production takes this one step further; here, researchers work with these individuals throughout the entire project – from start to finish. (more…)

How IGHI’s Student Challenges Competition helped us in the fight against parasitic worms

By Laura Braun, co-founder of Capta, 2018/19 winners of IGHI’s Student Challenges Competition

Parasitic worms affect more than one sixth of the world’s population (WHO). They target the most marginalised communities that lack safe water, sanitation, and health care. These worms, including hookworm and the flatworms that cause schistosomiasis, are contracted through contaminated water, soil or food.

As the global healthcare community has been consumed with managing the COVID-19 pandemic, a wave of cyber-attacks against healthcare organisations has emerged. Cybercriminals and hackers are upping the ante in creating more havoc and exploiting the fear and confusion that the COVID-19 pandemic has brought with it. The threat is global: Interpol even issued a warning signalling the need for healthcare organisations to be vigilant and aware of the heightened risk of cyber-attacks. (more…)

Tackling Type 2 Diabetes in North West London

Type 2 Diabetes (T2D) is one of the greatest challenges currently facing the NHS, with growing levels of obesity contributing to a large increase in the numbers of people with the condition. The disease can lead to serious long-term health problems – including heart attack, stroke, kidney failure and sight loss – which have an enormous impact on the lives of patients and their families. And it is these complications that account for most of the healthcare activity and cost associated with T2D. (more…)
