What does 5G and the IoT mean for health tech?

What is 5G?

Like many acronyms, they are demystified once you know what they stand for. 5G simply means the fifth generation of wireless technology. In simple terms, it means speeding up the data due to bigger channels, more responsive technology due to the lower latency or less lag, and the ability to connect a lot more devices at once. Within 5G, these qualities can differ depending on the channels used. For example, the speed itself may be slower if the frequency being used is lower and similar to that used in previous technology, such as old TV frequencies or current 4G. It may be all that is available if the physical infrastructure for the new frequencies is not available.

Where can I find it being used in health?

Decreased latency leads to less “lag” and, therefore, a more real-time experience. Whilst a delay during a videocall is annoying, it is generally not life-threatening. Transfer that to an operating theatre and the ability to operate remotely does depend on real-time transfer of what is happening, and vice versa, the ability to react and stop unexpected bleeding or coordinated efforts between various surgeons.

Similarly, the ability to connect more devices at once is of great importance in ever more connected health care settings. Physicians are forever being asked to adopt the latest wireless monitoring and sensors to create a more seamless experience for the patient. However, if you are still in a system that uses fax or in a department where the internet connection is flaky, the real game-changer for day to day use will be the ability to connect all the devices at once with confidence. In telemedicine, this translates into the ability to not only be seeing and communicating with the patient but also monitoring and receiving real-time data about their physical status. Many experts in the digital health space see these qualities as the gateway to 4P medicine, which is a digital version of what clinicians have been doing for years. 4P stands for predictive, preventative, personalised and participatory.

Another bugbear of out of hours care or just seeing a patient who does not usually attend your hospital or surgery is the inability to see their previous images. Imaging studies are notoriously complicated to transfer between systems and the ability for either the patient themselves or another health professional to send over quickly in a compatible format MRI or CT scans. It may surprise you to know that as a clinician in the NHS, I could not access the recent CT head scan of a patient done at a hospital only 25km away. Or maybe it’s no surprise, and you just shake your head as an inevitable reality. But we need to demand from our clinical workspace the same fast internet and communication we get from our Netflix subscription!

What is the IoT?

IoT simply stands for the Internet Of Things. In other words, “objects with computing devices in them that can connect to each other and exchange data using the internet”. In healthcare, this translates into sensors and technology linked to the patient rather than the clinical setting giving a real picture of what is going on in a person’s life and health. From distance monitoring which is set to alarm the clinician when certain parameters are reached, to active ongoing monitoring that transforms the patient’s home into a virtual hospital, the IoT with 5G gives clinicians more confidence to extend already existing hospital at-home projects. Well established in older and more frail patients, hospital at home with CGA (Comprehensive Geriatric Assessment) has already been shown to decrease hospital admissions with similar long-term outcomes and greater patient satisfaction.1 Distance monitoring will open this option up also because the carers and patients themselves will feel more supported and empowered. In France, where cancer patients wishing to stay at home are limited by the clinician not feeling with that confidence, a better solution may be found with real-time monitoring.2

Of course, no one person is just a patient or a disease, but rather a combination of roles, identities and functions. Where the IOT comes into its own is bringing all of this to the clinician, the information from all sources, including non-medical aspects such as travel, air contamination, favourite activities, brings clinicians closer to the original definition of being a doctor. When you would have known your patients, their families and everything else going on in their lives. This lack of continuity and depth brings many clinicians to burnout, and 5G and the IOT should be seen as facilitating a return to that holistic vision of a person or patient who comes to see them. Only then can the clinician use their knowledge base and experience to personalise the treatments and solutions they offer fully. Digital health augments a clinician’s practice. Those who argue that doctors will become irrelevant have clearly not sat in on patient clinics and surgeries, going through the options available based on local resources, the latest advances and patient preference. In medicine there is never one right treatment, and the art remains in the ability to pull it all together, making use of all the information and resources available.

AR in medicine. The future?

What is augmented reality in medicine?

Augmented reality, or AR, is a relatively new technology in which a computer-generated image is superimposed on the user’s vision of the world.1  To create this augmented reality, hardware such as headsets, smart glasses or mobile devices are used. The difference with virtual reality is that the user keeps a link to the surrounding physical world.1

Augmented reality has many uses in medicine. These include medical training, especially anatomy but also simulation training. Surgeons can use AR to plan surgery, and all physicians can use AR to explain complex situations to patients and their relatives.2

Diagnostics

In diagnostics, AR has been used to improve adenoma detection rate. A combination of computer vision algorithms and a large database of colonoscopy polyp images means the endoscopist gets real-time visual assistance. Images are overlaid on the primary monitor they are using or on an adjacent monitor.3

Therapeutics

Therapeutics is another area where AR has been extensively used, especially in rehabilitation. The interactive aspect means that patients are encouraged to improve their motor actions.4 For people with severe mobility issues, including the elderly and paralyzed, AR becomes an integrated part of their daily life as part of a home appliances system. AR interacts with brain-computer interfaces to give back patients a degree of autonomy.5

When ultrasound was brought in, a new 2D perception of a 3D space was needed. Anyone who has ever used an ultrasound knows that this involves retraining your way of looking at spaces in what I felt was initially counterintuitive.  Ultrasound-guided biopsy is a minimally invasive procedure for tumour staging. Still, it requires long training not only on a manual technique level but also taking into account the change in perception of space. AR is used to plan the trajectory of the needle and then execute the process. A robot arm with pressure sensors is used, feeding back high-quality information to the operator. The person undertaking this ultrasound-guided biopsy is then able to overcome any needle deflection or target motion.6 

Training

Anyone who has taken a basic or advanced life support course will remember meeting Resusci Annie, the rubber mannequin used to simulate emergency situations. Although a great resource for many years, there was never any doubt that you were dealing with a floppy doll. High fidelity simulation training uses complex mannequins who can breathe, have a variable heartbeat and affect ECG readings which take training to a level. The ultimate challenge is simulation training with a real person, but there you are limited to one hopefully stable pathology, and obviously, you can’t administer medications or electric shocks. When it comes to training in anatomy, there are financial, ethical and supervisory constraints on the use of cadavers.7

You also can’t see inside the body, and this is where AR takes medical training to a whole new level. One setting is airway training, where learning to intubate often means switching between the student and instructor who attempts to explain what they are seeing and how best to proceed with the tube. In surgery, AR laparoscopic training too has been shown to increase trainee skills, especially when combined with physical models.3 This freedom of sight is also a safety aspect.8 In addition, AR means the training can take place in a professional work environment, undertaking real tasks. Depending on the program used, this training can be independent without the need for an instructor to be constantly there.7 Emergency medicine training has already been done remotely using AR as distances can be a real issue in more remote clinical settings.9

There can be some disadvantages. Sometimes trainees find that AR can lead to dizziness or blurred vision, although less than with VR or virtual reality.7 Cost is another consideration, although this may be less important to students and institutions who see the skill gain as non-negotiable.

How soon will AR come into my practice, and how should I prepare?

Google Glass was the forerunner of easy access VR and which some considered being low-level AR. Some of you may have tried out these glasses in a non-clinical setting. Google Glass is a good entry-level AR due to the familiarity of the concept. Many of us already use normal eyeglasses. The first version is now obsolete, but the 2020 revised version has been launched with an increased facility for developers to build their own software.10 Now more than ever, as a practising clinician, if you think of a solution for an everyday frustration, you can approach developers to build it for you. The hands-free aspect in a sterile or semi sterile environment is an attractive proposition for situations where you need access to information but don’t have the staff, such as in primary care. Being able to easily scan patient records without the need to be looking at a computer all the time would in itself make a lot of patients and doctors happy.10  In the same way as AR has helped with polyp identification in real-time, external dermal or other lesions too will be superimposed with AR and the corresponding algorithms and knowledge databank.

However, machines, like humans, are not infallible and knowing where they may fall down leads to using them more safely. Although some authors claim that AR will be trained to see with fidelity and without bias, bias in algorithms is only now starting to rear its ugly head.3  There have been several high profile cases of algorithms misidentifying people of colour in facial recognition programs.11 The algorithm will only ever be as good as the input data, even if the data is extensive in quantity. Humans choose the data which will be used, and we all have our own unrecognized biases. Hidden or unidentified health inequalities are often a direct result of these biases, whether race, age or other.

Physicians may be concerned with privacy issues. In cultures where scribes writing down the notes are usual practice, the idea of someone doing the same thing remotely as you use google glass or another similar device may not be a problem.10 For other clinicians, this may take a bit more getting used to. The developers need to think like a doctor, like all doctors, to overcome resistance. Perhaps some clinicians prefer to have limited options, not all of them. At least at the beginning.

What do patients think about it?

It’s very hard to know what patients think of their doctors using AR. There is a lot of information available projecting on to patients what they should be thinking and how they should see improvements. Yet this may not be the reality. We need to ask them and listen. Specific AR therapies have good outcomes as defined by the study researchers, but you don’t know what you don’t know. Perhaps dizziness may be too much of an issue, or perhaps there are other side effects or worries which have yet to be voiced. As with telemedicine, these reticences can often be overcome once the real underlying worries are identified.12

So what now?

AR is one more technology that will come to the patient interaction. It’s only a matter of time. Like POCUS, point of care ultrasound, there will be fans and detractors. Individual knowledge and training are the keys, as is listening to patients. Even if you don’t like it, your patient may have heard about great outcomes for their specific condition. Or you may be encouraged by the increased safe prescribing options of AR but find that you lose patient engagement, and much as the course of antibiotics is not finished, the AR stays in the box after the first couple of days.

If you’ve had any feedback or have any thoughts on VR or AR from your patients or yourself, I’d love to hear from you. @alice_bbyram on Twitter or email me abyram@ab-health-solutions.com.

Sorting the wheat from the chaff. Choosing a digital health app.

Why use a digital health app?

With more than 90,000 digital health apps being added in 2020 alone, physicians are bombarded with download options as much in their professional life as in their private life.1 However, not all apps are equal, with the top 110 apps accounting for almost 50% of all downloads.1

So why use a digital health app? It might seem like an obvious question, but like anything related to screens, it is important to think about apps in a meaningful way. Especially in a professional context. The answers to the question include convenience, safety, and extended knowledge. Or do they?

The days of the trainee carrying around a well-thumbed Oxford handbook are over. Now the entire Harrison fits into your phone and then some. However, I’m sure that I’m not the only one who has excitedly downloaded a textbook to never look at it again. The format of the information needs to be easily accessible in a clinical context. Sometimes you need to know the pathology exists to look for it. In a book, you can thumb a few pages forwards and backwards and, serendipitously, come across the diagnosis.

You also need to be able to personalise your reference tool, adding to it as you go along. Whether it is a dedicated notebook or lines in the margin, many clinicians add local protocols, bleep numbers (yes, they still exist), or extra tips learnt along the way. Often this can take form in a digital form of a notes document on your phone.

There is also the credibility aspect of checking a written text in front of a patient. Somehow looking up a dose on a phone is not the same as checking a paper format. Having said that, no one will argue with the fact that a doctor cannot memorise all the medical conditions and drug dosages. Having a digital memory aid, especially when tired, can be a question of safety.

Another argument favouring digital health apps is that they can easily extend your knowledge to any area for which you can download a protocol or handbook. For non-dermatologists, there is a wealth of image banks with or without artificial intelligence to aid diagnostics. Of particular note is Malone Mukwende’s Mind the Gap project with St George’s hospital in London to reduce the health disparities in diagnosing skin pathologies in people of colour. Of course, providing an online platform of images that can be updated is not the traditional definition of a digital health app. Still, it is arguably one of the platforms which will have the most impact. And the app will surely follow.

However, no doctor is an island and conversations between different specialities, whether family medicine and oncologists, further everyone’s knowledge. An app can never replace an interactive discussion about the best treatment for a specific patient, taking into account the available local resources, patient preference and social context, and preferred outcome. Indeed these conversations often lead to recommendations of more specialised resources. In this day and age, these recommendations often include health apps. Anaesthetists have been at the forefront of apps and are particularly good at knowing which apps are best for drug dosage or retrieval. Family and community medicine physicians often can point you to aids to avoid pharmacological interactions or diagnoses that span various organ systems. Physicians use a lot more health apps than you might think. And the ones they use will be the ones that work. If you have any that you would like to recommend, please send them to via Twitter @alice_bbyram or email. This brings us to the question of validating apps and knowing which ones are safe to use in your daily practice.

What do clinicians need to consider when choosing a digital health app?

When you do decide to use a health app, there are several aspects you need to think about before you start using it. First of all, is the device you will be using it on. Whether it is a personal or professional phone or computer, the memory needed for the app may affect the speed your device runs at. All portable devices should have a remote wipe and automatic delete after several unsuccessful login attempts.2 Of course, if the hospital computer is constantly updating windows XP or the websites are blocked by generic hospital controls, there is a natural selection as to which digital resources you have access to anyway. Similarly, suppose the app is a hybrid version that needs online access to give you all the information you need. In that case, you may find yourself limited by the WIFI available at your hospital or health centre.

            The individual using the apps or digital resources needs to recognise their own limitations. Few physicians receive formal digital health training, which is particularly important for prescription-only FDA-regulated digital resources.2 There is no shame in recognising that we have been washed along with the tide of innovation and haven’t any time to stop and steer our own course. This self-knowledge is fundamental when you consider how much health care professional input is required by the app. Some diabetes apps require quite extensive physician input.1

            Much has been made of the advantages of digital resources in aiding both physicians and their patients, with evidence available supporting the inclusion of digital health tools into health pathways. However, independent organisations caution about the need for more in-depth and long-term research to get a true picture.1 Physicians have a history of being cautious when sold new products by pharmaceutical representatives, for example. Digital health solutions are no different, especially when free. If the product is free, you’re the product as was so aptly demonstrated in ‘The Social Dilemma’.3 It is a valid question to think about who has the resources to set up and maintain a digital health resource.

Compliance and regulatory controls are mandatory for certain types of digital health rather than wellness apps. Still, you have to be aware that being American HIPAA compliant may not mean that an app is also compliant with European GDPR. The focus is different as the GDPR are person-centred, whilst the HIPAA regulations are arguably more focused on the business that deal with health data. You need to make sure that the regulations align with your personal requirements and beliefs around health data.

            National societies provide their own guidance. The Royal College of Physicians, for example, clearly states that you should not use web apps that don’t have a CE mark.4 And it is also up to the individual physician to make sure that it is up to date. Indeed, the college cautions against about being lulled into a false sense of security if you see a CE mark and has produced a fact sheet to help you decide whether you can feel confident about using a certain app.4 Even then it is up to the individual physician to exercise professional judgement when using the app. If you do see any calculation errors you are under obligation to report it to the MHRA.

            Digital formularies provide a library of available apps which could be held to a higher standard than an app store. The NHS has such a library of apps that have been passed according to the DTAC or Digital Technology Assessment Criteria for health and social care. This is a good starting point when you want to find an app covering a specific condition. However, users should be mindful of a possible increased cost due to exclusivity deals or newer and potentially better apps being excluded.2

            Finally, physicians are the end-user testers and are in a unique position to identify issues that come up. There is a professional obligation to flag up any prescribing or other issues that may impact patient care, but there is also the possibility of making a real change.5 Just as Dr Mukwende did with his dermatological diagnoses for people of colour, if you identify a need you can approach the innovation department of your hospital. Barcelona is a hotbed of digital health innovation, and places like the Barcelona Health Hub are spaces where digital health solutions are found by linking clinicians and tech companies.

What do patients need?

As physicians, we all know the need for medications to be easy and practical to take, and if not, the patient will understandably find it difficult to feel engaged. Digital health resources are no different. If an app takes up a lot of phone memory or is not easy to navigate, it will be quickly deleted. Conversely, integration with wearables such as smartwatches may lead to greater compliance. Word of mouth is also important amongst patients, and once one person sees the advantages of an app, others may well follow.

            Yet digital health technology can lead to exclusion. In fact, you may not even be aware of the exclusion your patients are facing. Sitting in a doctor’s waiting room recently, I saw a granddaughter teaching her grandmother how to read text messages to make sure she didn’t miss health care appointments. Now that, in some countries, appointment letters are no longer routinely sent out, you may not be aware of the level of patient exclusion. Specifically, newer methods for accessing appointments were found to be the place where most patients gave up.6

            Healthwatch UK found that exclusion can be linked to a lack of digital skills, affordability and trust concerns.6 However, it also found that statements about reluctance to use telehealth should not be taken at face value as once barriers are overcome, patients may be happy with telehealth options.6

Developers listen up!

When it comes to developing a new app you may have been commissioned by a physician who has seen a gap in the market or by a team who come from a more business background. The end-user is still the same. Patients and physicians along with their team, their family, carers, nurses and other health care assistants or HCAs.

Diabetes, mental health and life style change apps are all well established, but have you thought of patients with AIDs, chronic pain and infectious diseases? Also be reactive to what is going on around you. During the COVID pandemic there have been spikes of related apps peaking with each wave.1

The first step as an app developer is to consider what is needed, rather than what you can offer. Your expertise may lead to many functions but if they are not useful in day to day medical and home usage, the app will be quickly deinstalled. Consider also the accessibility and ease of use. Stay up a night or set an alarm every 3 hours to reach a sufficient level of tiredness and you can start to get into the skin of a physician or carer on call. If you use glasses, hide them somewhere in your house that you can’t find just when you need them most. If you don’t use glasses, borrow some to get that sufficiently fuzzy vison that many people have to deal with. Then reconsider if you app design still works.

Overcoming the reluctance of end users is a team effort, right from the start. Not just relevant to the sales team. As a developer you have to make sure that your app is secure by design and complies not only with country wide compliance laws such as HIPAA or GDPR, but also institutional ones such as in the NHS. Go straight to the end requirements that the physicians and patients will be requesting. The NHS Digital Technology Assessment Criteria for health and social care has an entire section on the requirements which should direct your development. These include clinical safety, data protection, technical security and interoperability criteria. To make your life easier as a developer there is tick box exercise for you to work through to make sure you are complying with good practice by design. Apps need to be accessible to all, follow ethics guidelines. From a technical point of view, you need to be up to the IEC 62304 international standard. Your app must undergo verification, validation and load testing as part of the development process. Bias testing is another aspect for which you may need to seek outside expert help. Humans are notoriously bad at recognizing their own biases.

            In the UK the Caldicott guardian principles are the benchmark for physician decisions when it comes to data protection. This is more likely to be used by physicians than the GDPR which post Brexit will be incorporated as UK-GDPR.  

Physicians are under obligation to report to any problems with an app which may lead to error to the MHRA depending on where they are practicing. You need to provide an easy feedback form to make sure you are also informed and react proactively rather than defensively.

You should be aiming for the CE mark whether the app will be free or not.5 and make sure that you have thought ahead how your health technology may evolve but also how the requirements may also evolve. If you are thinking of expanding to different markets, knowing in advance where the security emphasis is placed is invaluable.

Similarly, looking at the digital formulary of apps you may wish to be included in can help you overcome potential problems of being sidelined for not being updated or outpriced, a couple of the potential disadvantages of digital formularies.7

Finally, we’re all patients or carers/family of patients. So take off your designer hat and ask around you what works in an app. If you are working with a specific condition, speaking to the patient associations for people with that condition will not only help your design but also open doors whilst you are doing it.

In a nutshell.

  • Compliancy may come in many different forms – always use professional judgement on any decision taken.
  • Knowing who is behind the app can help you make decisions and even offer feedback.
  • Practicality has to come first be that automatic updates, storage use, interoperability and hybrid options
  • Think of possible patient exclusions to the digital health option you are offering
  • If you develop an app that is intended for use in any medical context in Europe, it will need a CE mark, whether it is free to download or not.
  • Knowing the criteria used for regulatory compliance can help you as a clinician decide if it is an app you feel safe using.
  • If you see a need be reactive and either develop the digital health resource yourself or go to the people who can help you or take it over.

In short, digital health resources are valuable, not necessarily an intrusion. When used mindfully, they can be a help, not a hindrance in your practice.

Straight from the horse’s mouth – or where to go for verified information about #coronavirus or any other medical topics.

If you work in #digitalhealth it is important that you deal only in facts and validated information to retain credibility.

Over the past years, months and days, we’ve all been exposed to #fakenews in one form or another. Some of it is obvious and maybe even funny. Other fake news maybe less obvious, especially if it comes through a friend or colleague. #coronavirus has led to many fast circulating examples of misinformation so here is a quick guide to how to make sure you have up to date validated information and a list of specific #COVID19 resources.

We often don’t know where to go in the middle of so much available information. Newspapers often get their information second hand and report , as is their function, on ever changing situations early on. Blog posts can look surprisingly well referenced but if you go into the references maybe citing animal studies or non peer-reviewed articles. Did you know that many journals now ask authors to pay for their article to be published, knowing they have a willing market in researchers needing to publish a certain amount of articles a year?

Other sources of potentially biased information due to having vested interests are patient information webpages which appear at the top of google. Often pharmaceutical companies or pressure groups have invested a lot of money in making sure that their page appears first when you type in their name. It may take a while to find out who is behind the page – a red flag in itself.

So where should you look?

The best sources are official, have an obligation to be updated regularly and have been reviewed by someone other than the author. Looking at the site where the information is hosted is one of the first steps.

  1. .ac.uk – university sites in the UK
  2. .gov – official government sites
  3. .nhs.uk – the National Health Service in the United Kingdom
    1. NHS Patient Info
    2. NHS Specialist Info
  4. .org – if combined with it being the national college of a medical speciality, it should be a reliable if not always very easy to use source of specific medical information
  5. .edu – a educational institution which may be a university hospital with information for healthcare professionals and patients.

Clinical guidelines and updates are often published by national societies but there are also a few other places to look:

FDA: The U.S Food and Drug Administration website has a lot of regulatory information but also updates on current events such as donating plasma if you have recovered from COVID-19. Use the search option to find information about your topic of interest.

NICE : The National Institute for Health and Clinical Excellence is a UK based organisation on which clinical protocols are based. if you want to check what is the is the latest guidance on a specific health issue, including coronavirus, then this is a good place to start. Don’t be put off by the sometimes dense text, there is always a summary option available.

For research papers you can look at PubMed where almost all research papers are collated, with links out to the originals and links to other articles citing the information provided in your chosen article. You can specify how recent you want the article to be and whether you are interested in just humans or also animals. Using the “review” filter means that you will get an article looking at all the research on a particular topic. This can be very useful for the general public or non-specialists. You can also set up alerts so that you receive an email every time someone publishes something in your field of interest.

If you do receive a whatsapp or facebook message purporting to come from Stamford University for example, copy and paste the first line into google and you will quickly find out if it is a scam or not. Even videos with an MD explaining something may not be validated information. Always fact check anything you receive.

Specific COVID-19 or #coronavirus resources.

In view of the fast changing events it really is best to go straight to the horse’s mouth, or the specific #COVID-19 pages of the ones informing the experts and the general public:

  2. British Medical Journal – Best Practise
  3. John Hopkins Coronavirus Dashboard.
  4. KnowledgeShare compilation of articles and guidelines coming out.

If you want to hear it from those on the ground.

Front-line health workers whether doctors, nursed or paramedics have taken to podcasts as the way of reflecting on their experiences and how it fits in with the evidence. They are ahead of the official guidelines especially in fast-changing situations such as the current coronavirus pandemic.

EMCrit – USA based emergency physician and guests.

The Good GP – Australian Family Medicine Doctors talk about their experiences and latest updates.

Emergency Medicine College explains how to deal with COVID19 for non-EM doctors.

Pondermed – talks about the reality for radiographers amongst other COVID-19 topics.

Paramedic podcasts – prehospital health workers are the first people on the scene and have a unique view on what actually works and is really going on.

Why your #healthtech pizza can’t have too many toppings.

Have you ever been so exhausted with making decisions at work that you decide you just want pizza for dinner (any pizza, as long as someone else decides the toppings)? This decision fatigue (1) is a very real experience for all types of doctors and health professionals who spend their day taking important decisions with life or death consequences immediately or in the future. There has even been a scale developed to assess how health professionals are affected by this (2).

So when you present your amazing healthtech product with its many multiple options to clinicians, don’t feel offended that their eyes glaze over, or even droop. It’s not a case of reducing your offer of special functions available exclusive to your digital health product. Instead, tailor your product to the needs of the health professional in front of you.

What you really need to do is to know which functions will change their practise, decrease their levels of frustration with IT and set it up for them. Of course, they can do it themselves (this and a few more complicated procedures such as saving lives), but if you do it for them, you get a foot in the door. Leave it to them, and it will be pushed to the bottom of the non-urgent pile, and that is how digital health products end up not being implemented.

You can rail against health professionals pushing back against tech, but the reality is that if it doesn’t work for them, you are going to be the one left on the outside.

Lost USB? Hacked? What to do in the case of a data protection breach?

Despite all the best will in the world and processes in places, data breaches can happen. It can be as simple as a lost USB with patient information or a more sustained hacking attempt which affects only your clinic or you as part of a wider organisation which has been maliciously attacked.

Informing the supervisory body.

The most important point is that you have 72h to inform the supervisory body as soon as you are aware of the breach as per Article 33. If you don’t do this within 72h, you must give reasons as to why this wasn’t done. The information you will need to provide is:

  • Nature of the breach:
    • Categories of data subjects
    • Numbers of data subjects.
    • Numbers and categories of data records affected.
  • Data protection officer contact details as well as those of other people who may be able to give relevant information.
  • Explain the potential consequences of this breach.
  • Explain what you have done so far and what you plan to do to mitigate the effects of the breach.

Informing the patient.

Once you have informed the supervisory authority, you need to notify the person whose data has been breached (data subject) in clear and plain language. As per Article 34, you do not need to inform the patient if:

  1. The data was encrypted or used other methods to ensure that it is unintelligible to persons not authorised to access it.
  2. The data controller has taken extra measures to ensure the risks of the data breach are not likely to materialise.
  3. It would involve a disproportionate effort. Public communication would be the alternative in this case.

If the supervisory authority feels that this is a high-risk situation and you have not informed your patient/data subject, they make take on the task of informing patients about the data breach and its potential consequences.

Why you need to clinically validate your #healthtech.

Quoted failure rates of #healthtech start-ups are almost as hysterical as the millions said start-ups are said to be receiving. Numbers vary vastly from 44% to 70%. The actual numbers don’t really matter (unless you are one of the investors or workers losing out), the real issue of how to avoid this happening in the first place in #digitalhealth. #Healthtech projects which have clinicians behind them do well both in the private and public sector; they have inbuilt clinical validation from the start. This is why you too should think about doing it. 

So that the #healthtech actually works.

It may seem an obvious point, but many digital health “solutions” fail because they are not in fact a solution. They are a product which is developed by non-healthcare professionals to answer a perceived need. Innovative technology is showcased brilliantly at industry events but then is either rejected or fails when it comes to the medical profession.

Bias in medicine is a dangerous thing, and as clinicians, we are continually being put in our places by patients who don’t conform to expectations. There has been much talk about Babylon’s diagnosing a woman as having anxiety instead of a heart attack, pointed out incidentally on #medtwitter. However, this is just one of many examples of bias which can mean that your non-clinically validate #healthtech not only doesn’t work but also becomes a liability. And as with Babylon, word spreads fast in the medical community. How many #healthtech developers are employing data scientists to look at potentially dangerous biases in their algorithms?

So that doctors support your #healthtech.

Lack of clinical take-up leads to a lot of “doctors will just have to get used to changing their practise whether they like it or not” comments, implying that they are stuck in their ways. This overlooks the fact that doctors, by definition, are lifelong learners, adapting their clinical practice on a daily basis. Every patient you see is a risk-balance assessment of what works best for that patient based on current evidence but also your own professional opinion. Healthcare professionals are your toughest critics because they are the ones who see the #clinicalreality and the aspects which you don’t. No man is an island and no patient is just one disease.

When you diagnose a patient, you do so not just by looking at a set of tests and variables such as heart rate, but by speaking and looking at the patient. The questions often seem random to a layperson, but sometimes the examination is even superfluous. I know I’m not the only person who has gone back into a cubicle to put a stethoscope on for the patient’s benefit as I’d already understood what was going on by the time we’d finished talking. Just how many #digitalhealth people realise that by the time you are ordering the tests, you are often just confirming the diagnosis. When you “treat” a patient, you do so not just following a protocol but based on many other factors.

However, there are many frustrations which we know technology could help with; having access to all the correct patient information, reducing the decision burden by incorporating protocols. So speak to your target clinicians. Now. Often. In their clinical setting. What they will tell you is that they will enthusiastically take on validated and evidence-based #healthtech which answers their needs. In fact, they will probably be able to tell you what you need to do to make your #digitalhealth technology work. Sometimes they have already done it themselves, and you can work with them.

So that patients go to their doctors asking for your #digitalhealth solutions.

And if you speak to the doctors, and nurses, and healthcare assistants, and receptionists, and porters, don’t stop there. Patients, especially chronic patients, have a very clear idea as to what works, what doesn’t work and which of their #digitalhealth needs aren’t being met. There is a whole #wearenotwaiting movement where type 1 diabetes patients have been going faster than the industry at developing openAPS or open artificial pancreas systems and glucose monitoring. After many years of being treated as dangerous mavericks, they are now being incorporated into paediatric diabetes care in major NHS hospitals. Even the fact that they are not FDA approved has not put off parents and doctors using them. That is what “disruptive” in #healthtech really means. Meanwhile, Medtronic and others who provide the “official” solutions, have recognised the fact that it makes more sense to employ directly the #wearenotwaiting developers rather than play catch-up.

Even patients who are not digitally savvy will be quick to tell you why they will or won’t use an app or technology. And often these are for very different reasons to the doctors. Maybe it is because they are more affected by the short-term side effects of a medication whose dose needs to be changed than targets- and they have to be able to access that information quickly. It may be that your amazing frailty support system doesn’t recognise the fact that being part of the #silvereconomy doesn’t mean being bedbound, and that they too want to go places in the world with no internet connection. Patients are whole persons whose disease lives with them once they leave the consulting room, and any treatment, digital or traditional, needs to take that into account.

So that you can expand into the community.

It is fair to say that in an era of influencers, traditional advertising is being rethought to reflect the age-old concept that you are more likely to follow the recommendation of someone you trust that the manufacturer. Doctors, suspicious as they are (!), prefer to hear about new medications and developments in medicine from other doctors. Pharmaceutical companies have long recognised this fact and this is another advantage of clinically validating your product. You speak the language of your target users, and once clinicians are prepared to listen, it can be a useful two-way conversation and is the way you get your #digitalhealth product to a clinical setting.

Patients too ask friends and family for advice. The reason that the instruction to only take medication which has been prescribed for you is precisely because people still take their family member’s medications for something which may or may not be a similar disease. Once you have patients with a vested interest, then others will follow. The way to do that is to listen, speak to and answer their needs.

It’s an exciting time to be in medicine, both as a professional and a patient or carer. It is in everyone’s interest in making sure that the progress in #healthtech works first time round….and keeps on working and being relevant.
