Co-creating digital health applications and digital therapeutics (DTx)

Why it matters to obtain patient insights along the digital health app and DTx development journey


Digital Health Applications and especially Digital Therapeutics (DTx) are perceived as an opportunity to innovate and create new business – particularly for the life sciences industry.


Within this context, there is a strong trend of moving more and more towards evidence-based digital solutions and away from the numerous life-style or wellness applications. Looking at this picture, one can observe that Life Sciences firms are willing to go much further than “beyond the pill” and into clinically proven digital solutions and applications. Yet, it seems that many application developers and providers (including life sciences firms) do not always fully understand how health apps fit into patients’ lives and how they can obtain clinical and real-world-outcomes to prove the case.


How can this be achieved and how can app developers and providers ensure that the patient voice is included throughout the development and commercial journey of an app?


In contrast to the many wellness and life-style apps, Digital Therapeutics (DTx), are software-based products for the prevention, management and treatment of health conditions. A feature of DTx is that they require both clinical evidence and evidence from real-world outcomes. As such, they need to be reviewed and approved by regulatory bodies for safety, risk and efficacy.


The German fast track process for digital health apps


Germany was one of the first countries that passed a legislative framework for this review process- the so-called fast track process. All digital health applications that have successfully completed the process can be prescribed and reimbursed within the country’s public healthcare system (these apps are often referred to as DiGa’s – Digital Health Applications).


However, in order to obtain DiGa approval, app developers or providers have to create evidence data beyond the Medical Device Regulation (MDR) certification. The needed evidence is usually generated in trials and observational studies (designed as randomized controlled trials) which involve the collection of real-world-patient data.


The following chart gives an overview of the German fast-track / DiGa process.



Key Learnings for digital health app developers & providers


As of August 2022, the total number of health apps submitted to the fast track process amounts to 147. Out of these, 33 apps have been approved and listed as DiGa’s. 93 apps have been withdrawn or received a negative decision.

The most prominent reasons for withdrawal or a negative decision are poor study design, real-world patient data collection which is not in accordance with the criteria for evidence-based medicine or simply the fact that no significant advantages or positive care effects could be demonstrated.


This clearly points to the importance of fully integrating patient insights into the app development right from the start to properly understand the impact of new digital health apps on the lives of patients as well as caregivers.


“Developers & providers should ensure to collect patient insights to get a better understanding of their preferences, daily lives and social contexts”


This will help them to identify the factors that influence patient behavior and enable them to develop apps that are able to show positive outcomes. Patient data collected prospectively would even more strengthen patient engagement and hence paint a very comprehensive picture for app development and sub-sequent regulatory approval.


This is especially true for rare diseases or conditions where there is little known about the outcome. In these cases, patients are often the sole real-world longitudinal source of information on disease progression, impacts on the physical and mental conditions or efficacy of treatment pathways.

It is of course true that the German fast track process for digital health apps is only one example of how apps can move towards becoming DTXs, but already a number of other countries are looking to the German model, so that it can be expected that similar criteria for digital health apps approval will be established on a broader international basis.


Engaging with patients and collecting their insights


Health app developers & providers possess different options to collect patient insights.


Moreover, they should also use a wider range of sources well beyond patients. Friends, family, employers or care providers can even give a wider understanding of the impact an illness has on patients and the difficulties they have in dealing with their condition in daily life.


Working with patient organizations or patient representatives throughout the app development journey can be very fruitful and often leads to higher levels of trust and acceptance among patients and care givers.


Here are some of the most prominent methodologies for engaging with patients and relatives and collecting their insights:


• Available patient preference information and insights • Structured / semi-structured Interviews • Quantitative online surveys • Focus Group Discussions • Patient advisory boards / community advisory boards • Patient round tables • Structured co-creation processes • Companion studies (running concurrently to the original clinical investigation)


Developers & providers need to ensure that collected insights directly and continuously feed into the end-to-end patient experience development and design. Collection of insights has to be done on a continuous basis and include the patient’s entire disease pathway, not just the few times a day when the patient actually uses an app.


Embedding a health app or DTx offering into existing business processes


For app developers & providers such as life sciences companies, health apps or DTx’s open up a chance to innovate.


A health app or DTx offering can act as a differentiator that is able to lead to new and attractive value propositions and resulting business.

In this context, digital solutions can work as a stand-alone therapy or are combined with drugs to improve patient outcomes, deliver value to patients as well as care givers and consequently drive business impact.


However, establishing a digital health offering is much more than just building a nice piece of technology.


“Very often, app providers spend 90% or more of time, effort and budgets on developing an app or finding suitable app partners, whereas they should not neglect the needed business transformation and implementation roadmap”


This area touches items such as organizational change or adjustment, business process review or the alignment of commercial practice. In a nutshell, critically assessing the way organizations have been doing business in the past and how this will change with the arrival of digital apps or DTx’s.


A sound digital strategy has to reflect these elements to avoid frustration and disillusionment from not attaining objectives.


The following graph summarizes and visualizes the different steps for building a sustainable and commercially successful approach – providing value to both, patients as well as app providers.




Setting up a sustainable patient & stakeholder engagement framework


Organizations that are successfully working along the lines of patient & stakeholder engagement look at this area as a strategic opportunity to differentiate themselves and consequently generate business.

To accomplish this, they see and deal with patient & stakeholder engagement as a long-term activity and not as one that is just carried out when the need arises or on a selective base.


Some companies have started to use patients & stakeholders as a “standing sounding board” to collect insights all along the development and commercial journey – not only for digital health applications and DTx, but also for their traditional therapeutic or diagnostic products. This is certainly going to play an increasingly important role for driving innovation in the life sciences industry in the future.
