Just as people scan their own shopping or buy their own airline tickets, they can increasingly carry out health-related tasks without attending a medical appointment. These might include entering symptoms before an appointment, monitoring health data or sending a photograph to their family practice for a minor concern.\r\n\r\nRoss gave the example of a recent eye infection. He sent his family nurse a photograph of his eye and received help without an in-person appointment. Such arrangements save time for both patients and healthcare professionals.\r\n\r\nStaff shortages are one reason healthcare is moving in this direction. This does not mean fewer doctors will be needed, Ross said. Complex illnesses, operations and treatment decisions will remain the responsibility of specialists, but digital solutions can allow people to carry out some simpler tasks themselves.\r\n

The current system knows more about illness than health<\/strong><\/h4>\r\nRoss says Estonia\u2019s health information system performs very well internationally, but has one important shortcoming. \u201cWhen we talk about a health information system today, we are essentially talking about an illness information system,\u201d he said.\r\n\r\nMost information entering the system is collected by doctors or other healthcare professionals: diagnoses, examinations and treatment. Much less is known about how people live between appointments.\r\n\r\nYet most illnesses do not develop overnight. Over the years, people may become less active, sleep worse, start smoking or gradually gain weight. Detecting these changes earlier could help prevent illness, Ross believes. \u201cPerhaps we could say ten years earlier: if you changed something in your behaviour now, you might enjoy more years of good health later,\u201d he explained.\r\n

\u201cHealthcare is a service sector, and service sectors are increasingly handing tasks over to customers.\u201d<\/p><\/blockquote>\r\n

Smartwatches collect data that doctors struggle to use<\/strong><\/h4>\r\nToday, information about our health is constantly generated outside hospitals too. Smartwatches and smart rings measure movement, heart rate and sleep; phones also collect data.\r\n\r\nThe problem is that different manufacturers\u2019 information sits in different systems. People who want to show their doctor data from an Apple Watch or another device must somehow extract and send it themselves. Doctors cannot work through files from dozens of different apps one by one.\r\n\r\nTalTech researchers are investigating how to standardise such data so it can be used meaningfully in healthcare.\r\n\r\nRoss used his own experience as an example. Working as a radiologist in hospital, he takes about 4,000 steps a day; lecturing at university, only 2,000; and in the countryside, 15,000. Seeing those figures prompted him to make a conscious effort to walk more on working days.\r\n\r\nThe main value of such data, Ross says, lies in tracking changes in an individual\u2019s health behaviour and offering suitable recommendations. The aim is not to give everyone identical targets. Even the common recommendation of 10,000 steps a day may not suit everyone. For someone who has had a heart attack, regularly taking medication or making a small but lasting dietary change may be far more important.\r\n

The Health Portal could gain a section for personal health data<\/strong><\/h4>\r\nPeople may currently be asked repeatedly by different doctors whether they smoke, but the answer often remains as free text in separate information systems. Meanwhile, the National Institute for Health Development collects smoking data through separate population surveys. Ross says this means the same information is collected several times, while existing data remains difficult to reuse.\r\n\r\nUnder a new solution, smoking data could be brought together in a standard format in the Health Portal and updated by both healthcare professionals and individuals themselves. The same question would not have to be repeated every time, and changes in smoking habits could be tracked over a longer period. The same data could also help assess population health. \u201cInstead of sending a questionnaire to a few thousand people every two years, we would effectively have data on the whole population,\u201d Ross explained.\r\n\r\nSmoking data is the first step. Information on alcohol use, mental health, physical activity and sleep could later be added to people\u2019s personal health data view. Healthcare professionals would gain a better picture of what happens between appointments and could detect changes earlier.\r\n\r\nRoss said the smoking-data solution is hoped to be introduced as early as next year. Automatically bringing smartwatch and other device data into the Health Portal would be a subsequent step, requiring agreement on which data to collect, how to present it and how to use it in healthcare.","image":null,"align":""},{"acf_fc_layout":"image","image":9783},{"acf_fc_layout":"text","type":"text","text":"

In future, individuals could hold the key to their health data<\/strong><\/h4>\r\nRoss and his research group are also exploring ideas further into the future, including how to give individuals greater control over their health data.\r\n\r\nPeople\u2019s medical data is currently held by hospitals and national information systems. Although individuals have a right to access it, obtaining all their data and using it according to their own needs is not always straightforward. For example, an X-ray may not be downloadable from the Health Portal, requiring the person to contact the hospital instead.\r\n\r\nUnder the model being studied at TalTech, individuals would hold a digital key to manage their data and decide whom to share it with. They might give a doctor, carer or loved one access to part of it. Hospitals\u2019 obligation to retain medical data generated during treatment would remain. Ross acknowledges that this is still an idea for the distant future, with legal, funding and data governance questions to resolve. Yet the more his group explores it, the more potential he sees.\r\n\r\n\u201cWhen Skype arrived, it completely changed how we communicate \u2014 previously, we could not even have imagined such a possibility,\u201d Ross said. \u201cWhy could something similar not happen with health data? We cannot predict precisely today how it will be used in twenty years\u2019 time.\u201d\r\n
