A recent industry report by Fortune Business Insights stated that the global wearable medical devices market size was expected to showcase considerable growth by reaching USD 195.57 billion by 2027. Factors such as the increasing prevalence of chronic diseases and the growing awareness regarding fitness and wellness amongst people are expected to drive the adoption of these devices globally.
Medical wearables have emerged as an innovative tool for improving patient outcomes and advancing medical research. These devices, which are typically worn on the body, are equipped with sensors and other technologies that enable continuous monitoring of a variety of biological and physiological parameters. This provides researchers with a wealth of data that can be used to better understand disease progression, assess treatment efficacy, and more.
So what kind of opportunities do these medical wearables open up specifically for conducting clinical trials?
Patient Care with Real-Time Data
Medical wearables provide researchers with a unique opportunity to gather continuous, real-time data on patient health and well-being. This can be especially valuable in trials that involve chronic diseases, where the effects of the disease and treatment are often slow to develop and difficult to measure. Additionally, they can also be used for remote patient monitoring and tracking of patients’ health status in long-term settings, helping researchers gather information more efficiently and accurately than in a traditional trial setting.
Improved Patient Outcomes
Another major advantage of medical wearables is their potential to improve patient outcomes. By providing real-time data on patient health, these devices can help healthcare providers identify early signs of disease progression, monitor the effects of treatment, and provide timely interventions as needed. This can lead to improved patient outcomes and better health outcomes overall.
Wearables have proved valuable in monitoring many diseases, such as asthma, cancer, diabetes and mental illness. They can be used as ‘event recorders’, for example, to record cardiac arrhythmias and screen patients for atrial fibrillation. In the “WeSeniMuS” project (Wearable Sensors in Multiple Sclerosis), medical wearables are used to continuously monitor the health of patients suffering from multiple sclerosis and provide care as and when required.
However, despite their potential benefits, there are several challenges associated with the use of medical wearables in clinical trials.
Accuracy of the Data Collected
One of the most significant is the accuracy of the data collected. Medical wearables are designed to be non-invasive, but the accuracy of the data they collect is still subject to various limitations. For example, many wearable devices are not able to accurately measure certain physiological parameters, such as body temperature or blood pressure. Additionally, there may be errors associated with the data collection process itself, such as data loss or incorrect device placement.
Patient Engagement
Clinical trials often require patients to adhere to strict protocols, including the use of medical wearables. However, it can be difficult to ensure that patients are motivated to comply with these requirements, especially if they are uncomfortable or cumbersome to wear. In some cases, patients may simply forget to wear the device, or may not understand the importance of doing so. This can lead to gaps in the data that can compromise the accuracy of the results.
Ethical and Privacy Considerations
There are also a number of ethical and privacy considerations associated with the use of medical wearables in clinical trials. For example, there may be concerns about the security of sensitive patient data, as well as the risk of discrimination or stigma associated with certain health conditions. Researchers must take these factors into account when designing and conducting clinical trials that involve the use of medical wearables.
Conclusion: Medical Wearables Are Powerful Tools for Advancing Medical Research
While there are certain limitations and concerns associated with these devices, they also offer a powerful tool for advancing medical research and improving patient outcomes. In order to fully realize the potential of these devices, technology companies and clinical research institutes must collaborate to unite the different demands – in terms of material selection, robustness and measurement accuracy as well as sensor integration, Big Data and cyber security. Exciting opportunities can be unlocked from such collaborations.
