As people live longer and lifestyles change, more people are confronted with chronic disease. In addition to having a major impact on people's quality of life, this puts increased pressure on healthcare systems.

New wearable sensor technologies are rapidly becoming available and could play an important role in healthy lifestyles and treatment compliance. The current challenge is to turn the data these new devices offer into clinically relevant information. This will help build scientifically proven and clinically validated solutions to improve the outcomes of lifestyle intervention programs and medical treatments.

For this purpose, Philips and LUMC will jointly run clinical trials to identify and improve how people respond to lifestyle intervention programs. By analyzing health and wearable sensor data, the partners aim to gain fundamental new insights into how innovative technologies and coaching programs can effectively impact personal lifestyle and health - particularly in people who are at risk of or suffering from chronic conditions.

"We can use the data we obtain to assess new solutions and approaches for personalizing intervention programs that encourage at-risk people to make lifestyle choices, which help prevent the onset of disease, or promote treatment compliance in diagnosed patients," said Simon Mooijaart, MD, PhD, internist-geriatrician at Leiden University Medical Center. "This could help reduce the number of people admitted to hospital for treatment of chronic disease. Furthermore, once people have chronic disease or functional limitations, robust measurement of these lifestyle factors using innovative sensors can help in tailoring healthcare to their specific needs, ultimately improving quality of life in older age."

"The correlation between personal lifestyle and health is key in making the change from a reactive to a proactive healthcare approach in which we help people manage their health before chronic conditions develop and after they are diagnosed," said Henk Valk, General Manager of Philips Healthcare Benelux. "The fastest, most effective way to develop such solutions is to work with expert partners like LUMC, who bring the clinical insights and competencies that complement our own."

The clinical trials run within the Philips and LUMC collaboration will generate key data for developing algorithms to assess physiological and behavioral parameters such as activity, sleep, exercise and sedentary time. The partners will also work on algorithms to translate this information into insights on how users are adhering to their treatment plans and achieve their personal goals. A third focus area will be to develop analytical solutions for predicting parameters such as blood metabolites, blood pressure, blood glucose levels and cardio-respiratory fitness. This could enable the monitoring of health progress in people following a lifestyle intervention program.

While the initial trials will focus on elderly people, the results could lay the foundations for new solutions and services for people of all ages.

Chronic disease already accounts for around 70% of the global healthcare budget[1]. There is overwhelming evidence that lifestyle factors such as unhealthy nutrition, stress, sleep patterns and physical activity levels play a key role in the development of chronic diseases such as diabetes, heart failure and elevated blood pressure. Consequently, supporting people in making healthy lifestyle choices could help significantly relieve the burden on healthcare systems and improve people’s quality of life.

This new collaboration extends an already successful relationship between the two partners. As an example, Philips and LUMC are working together in extensive neuro imaging research programs to gain more insight into Alzheimer's disease.
