Seniors and Digital Clinical Trials - Opportunities and Challenges
Published: 05.12.2021
Germany’s population is aging, and clinical trials are becoming increasingly digital. This evolution opens new doors for involving older adults in research—especially through digital clinical trials and DCTs (Decentralized Clinical Trials). But what do seniors need to actively participate in a digital or decentralized clinical trial? Here's a look at the challenges, solutions, and potential benefits.
Demographic Shifts Are Reshaping Clinical Research
With an average age of 45.7 years, Germany is one of the oldest countries globally. Already in 2019, more than 18 million Germans were 65 years or older—a number that's still rising. By 2060, the population aged over 67 is projected to grow from 16.2 to 21.4 million, while those under 20 and between 20–67 will decline.
At the same time, digital technologies are transforming clinical trial development and execution. More data are being collected remotely using apps and wearables, enabling remote participation and reducing the need for physical site visits—a hallmark of the dct clinical trial model.
As the demographic shift accelerates, so does its impact on digital clinical trial design. Potential patients will continue to age, and with age comes increased risk of serious illness. Already today, many clinical trials use electronic tools for data collection, often via personal mobile devices.
But can this model scale as the average trial participant grows older? How connected are seniors to digital life? And why should they not be excluded from cutting-edge clinical research?

Seniors and Digital Technologies: A Growing Audience for DCTs
Can older people handle these technologies? The answer is yes - with growing potential. In fact, the use of the Internet by senior citizens is increasing year on year. A recent study by Initiative D21 shows that 85% of 60- to 69-year-olds surf the Internet and 72% use it on their mobile devices. More than half of respondents over the age of 70 are online, with 36% using mobile devices.
In addition to age, education also determines access to the Internet, according to D21. People with a high level of education use the Internet 98 percent of the time and 90 percent of them use mobile devices. In contrast, only 70 percent of people with a low level of education use the internet, while 60 percent use mobile devices.
It can also be assumed that the use of the Internet by senior citizens will continue to increase in the coming decades. This is because the Internet has long been part of everyday life for women and men aged between 40 and 60, the senior citizens of tomorrow.
An analysis by the Federal Statistical Office revealed that, with 12.7 million people, the 50 to 59-year-olds are the age group with the most Internet users, followed by the 40 to 49-year-olds with 10.6 million. According to the Federal Statistical Office, almost 100 percent of 14 to 59-year-olds already use the Internet.
DCTs Expand Access to Clinical Trials for Older Adults
Decentralized clinical trials reduce or eliminate site visits, offering new access to clinical research—especially for those with limited mobility. Participating from home in a digital clinical trial makes research more inclusive and patient-friendly.
For this to work, digital technologies must be secure, intuitive, and supportive. Digital tools should be easy to navigate and, if needed, complemented with personal assistance. This ensures that older participants can engage confidently in clinical trials.
Digital Technologies Drive Success in Modern Trials
Studies show that regular use of digital tools like smartphones and tablets can support cognitive health in seniors. The challenge of learning new digital functions boosts mental engagement.
That’s good news for digital clinical trials. To encourage participation, patients should be allowed to use their own devices (BYOD). Familiarity with their own technology simplifies participation and reduces the need for training.
That said, user-friendly app design remains crucial. Clear navigation and simplified data entry increase engagement, while complexity leads to frustration and dropout.
Transparency also plays a key role. Explaining study goals, how data are used, and the potential personal health insights available to participants helps build trust and boosts motivation.
Conclusion: Digital Clinical Trials for All Generations
The rise of digital clinical trials and the adoption of DCTs bring enormous opportunities for modern clinical research. Older adults are both able and willing to take part—when the approach is thoughtful and inclusive.
Today’s seniors are healthier, more active, and more digitally literate than ever before. With clear communication, supportive design, and easy-to-use technologies, they can be valuable contributors to decentralized clinical trials.
In fact, offering seniors meaningful health insights as part of their trial experience—along with convenient, remote access—adds both personal and scientific value to their participation.
An aging population is not a barrier to progress—it’s a call to design smarter digital clinical trials that meet people where they are. When sponsors, researchers, and developers include older patients in their planning, using familiar technologies and ensuring clear support, they unlock a diverse and motivated group of trial participants.
