Mobile health — the future of medicine? Pieter Vandervoort at TEDxUHasseltSalon



about a smartphone and sure the smartphone has been a very successful tool it hasn't been successful because of the technology it has been successful because of the communication and without communication if you do not get feedback if there's no information that is being exchanged even the fanciest of all our smartphones because becomes a useless device now today in medicine the smartphone is hardly being used to exchange information because there is no information that is currently being exchanged between the patient smartphone and the physician now that's going to change first of all iPhones are everywhere or smartphones are everywhere infrastructure is there and computing power is increasing now in order to make the smartphone a really clinical device we have to exchange information that will be relevant for the patient and provides him with information that will improve improve his care now in order to set up this information exchange we can do that in a two-tier system first of all the smartphone will has to be turned into some type of a self monitoring device where the patient can actually look at his own data measure his own blood pressure measure his own glucose levels and his smartphone will give him information how to possibly adjust some of the medications that he needs to take in addition the smartphone can coach him through exercise programs or through a weight loss program but far more importantly is the fact that we need to exchange this information we have to get that information available to caregivers imagine a specialized nurse your family physician or a specialist who will get this information they can look at it they can watch over your shoulder and they can intervene whenever something is going wrong this type of feedback to the patient will make this clinically relevant now as of today your smartphone has already some sensors available that could be good collect clinically useful information it has the camera it has a flashlight it has a microphone the microphone could collect information on your heart sounds or it could register your snoring at night possibly suggesting you have a sleep disorders a sleeping disorder it also has a flashlight and a and a camera and you can put your finger on the on the camera and the flashlight and it will take a few seconds before it is detecting my pulse but then all of a sudden it will start registering my heart rate that heart rate it's important because it does tell me whether my heart rate is within normal range and my heart rate is fast why because I'm not exercising but I'm giving a TED talk and giving that TED talk is important information to actually interpret that result it can be lower it can be higher now giving that information that could be very clinically relevant now let's suppose that someone in the audience were to faint we're not feeling well I have a camera and I could measure with the camera I could look at someone and I can look at the at someone's face and based on technology built in the camera it will register slight differences in in color and it will also register a heart rate so can you imagine what type of information that is available at the tip of your fingers just while you're having your smartphone at hand next to building features building sensors that you have right at hand there are on the market already a wide variety of sensors that you can hook up on to your iPhone this is one to one one thing one sensor that you can measure temperature with their sensors to measure blood glucose and are all a variety of sensors now this one is the one and only FDA approved sensor to measure your electrocardiogram it is like a case that you can hook up on your iPhone it is equipped with two sensors in the back and you can hold it firmly and then your electrocardiogram is available now this is information that in the past was only available in your doctor's office or in the hospital now you can read your you have you really have your electrocardiogram at your fingertips now it doesn't tell me only what my heart rate is and it is still rather fast but it tells me in addition whether it is regular or irregular in addition to the heart rate an electrocardiogram can also give me important information on whether I'm suffering a heart attack and there has been a case report where this type of information diagnosed a passenger and on an airplane having a myocardial infarction so this type of information is now available everywhere sensors don't have to be hooked up sensors can be in your environment and they can communicate with your cell phone short-range communication using Bluetooth high-frequency ultrasound it could be your weight scale it could be a blood pressure measurement but it could also be patches stick-on patches that you are wearing with built in sensors I am actually wearing a patch and it does have a building sensor that's measuring my electrocardiogram that electrocardiogram is being streamed and again now I need to go to my health desk I think oh here it is okay so now I'm wearing a sensor that is streaming my electrocardiogram through my smart phone and I can stream it anywhere now the advantage of a system like this is that it does it in the background as the previous speaker said to measure an electrocardiogram or whatever I don't need to do any action and it's not a snapshot in time if battery life or cost of communication was not a limiting factor I could monitor myself for 24 hours seven days a week using this type of system now patches can be equipped with multiple sensors this one has an electrocardiogram but it can be equipped with a device that measures registers my respiration rate my breathing pattern whether I have fluid buildup in my lungs and might be the first sign of a episode of heart failure so these patches or these sensors can be multi multi-sensorial they can but they can acquire lots of information they can also be built into my clothes imagine that you're going to go for a workout and you're wearing your sport clothes and it's measuring your vital signs this type of sensors could be built into the seat of your car measuring your vital signs while while drive in your car as of today there are already more sophisticated sensors that can be implanted into the heart and they will measure my my blood pressure pressures in the heart electrical activity or even hormone levels that may warn my or my physician that I'm going to have an episode of heart failure multiple sensors will be necessary to evaluate to follow up to monitor patients with complex diseases and multiple comorbidities now how are you going to solve this problem so what do we need to do well first of all the sensors need to be sophisticated reliable and clinically validated I have to be sure that what I'm measuring that that is real that I can make base clinical decisions on the numbers or the data that we collect algorithms have to be to be built to interpret all this information that is being collected and the previous speaker has said we are going to be monitored all the time your device will know whether you're asleep driving your car walking around algorithms we'll have to analyze the data and select the most interesting things so that the date only the clinical or clinically relevant information can be presented to the to the physicians and again we need doctors we need physicians who will interpret the doctors of the day are what we call the digital immigrants they still largely live in the landline era however the doctors of the future and some of them are sitting in the audience they are the digital natives they grew up with smartphones tablet PCs and the internet they embrace new technologies both in their professional and in their personal lives so the build up of a clinical call center with specialized nurses and interested physicians is absolutely necessary to look at these data to interpret them and to give valuable feedback to the patient's so smart phones of the future equipped with multiple sensors together with a smart algorithm and a feedback system to the patient will dramatically change the way we organise healthcare in the future and by the way you'll still be able to make a phone call with it you
