DiGA: App on prescription

Fostering healthy behavior, improving preventive care, and managing chronic conditions: medical apps can make personal health easier. After the launch of the Digital Healthcare Act (DVG) in 2019, Germany has turned over a new leaf in healthcare. Physicians in Germany can now prescribe digital health applications with the costs covered by statutory insurance.

The benefits of DiGAs (German: Digitale Gesundheitsanwendungen) are obvious: Patients always have them at their side thanks to mobile devices and can use them to self-manage their condition. Gone are the days when diabetics had to manually track their blood glucose levels and medications in a notebook which they then had to review with their physician. Diabetes data analysis is so much easier if the data is digitally transmitted to the doctor's office for subsequent assessment. Psychological training sessions or behavioral therapies for certain mental health or chronic diseases and conditions can also be managed via a DiGA from anywhere in the world.

DiGAs can showcase their strengths especially during the coronavirus pandemic: as a complementary measure, digital health applications can never replace the treatment by a physician. However, in times of contact restrictions, apps allow patients to self-manage their condition and reduce in-person doctor appointments, thus restricting potential COVID-19 exposure.

Medical apps – keeping things safe and effective!

Unlike many other medical apps, DiGAs are reviewed and CE-certified as medical devices, making them technically secure and compliant as it pertains to data protection regulations and data security requirements. Studies have shown that medical apps improve patient care and health. In Germany, these criteria are carefully examined by the Federal Institute for Drugs and Medical Devices (BfArM). At present, the BfArM temporarily or permanently lists twelve applications in the directory of reimbursable DiGAs ("DiGA directory") for patients, doctors, and health insurance companies.

Developers can use the so-called fast-track procedure for inclusion in the DiGA directory within a few months. In a interview, Dr. Benedikt Zacher, founding partner at DiGA Factory, explains: "One essential requirement is that the application is designed for the patient and not for the medically savvy user or the physician. The DiGA must facilitate communication and patient guidance, thus enabling partial self-management of the diagnosis, therapy, or healing process."

The app receives a preliminary admission into the DiGA directory if it meets various technical requirements, but no so-called positive care effects ("Positive Versorgungseffekte") have yet been demonstrated. The latter must be done in a subsequent test procedure.

"Mika" is one of the apps that has achieved preliminary admission. It targets cancer patients, provides information, and accompanies patients with a personalized support program that reduces levels of depression, anxiety, and disease and treatment-related symptoms. Prof. Anja Mehnert-Teuerkauf from the University Hospital Leipzig is involved in the development of the digital health application. She provides insights from the physician’s perspective in a interview: "We had to address many important questions pertaining to the tracking of the psychosocial effects of cancer on patients or the types of resources that can help patients to cope with their disease. We also discussed how this app can provide emotional support and foster self-management of psychological distress."

Unlike other health apps, the DiGA objective is not to offer a digital product that promotes a healthy lifestyle. A DiGA is intended to provide benefits for the patient and the healthcare system. Zacher also highlights this approach: "During the development process, it is essential to start with the desired end result in mind and work backwards from there. This means that you define the medical purpose of the product, and developers should work backwards and consider the steps that must be completed by the end of the DiGA process."

This means that potential providers of a digital health application must incorporate the certification and medical device approval process right from the start. This includes the plausible justification of the positive care effects, which – as with other medical devices – must be demonstrated in a study. Costs and effort increase exponentially if this study is treated as an afterthought and is conducted retroactively.

A model for other health care systems?

The German health care system tends to struggle with digital innovations. On the one hand, there is often a lack of standards and interfaces between the various sectors of health care, such as offices of physicians, hospitals, and health insurance companies. On the other hand, strict data protection regulations and privacy requirements in the healthcare sector subsequently mean that the introduction of digital products is a slow process.

The Digital Healthcare Act (DVG) and the Digital Health Applications Ordinance (DiGAV), which came into force at the end of 2019 will probably remedy the situation: "Germany is the first country in the world to quickly approve highly sophisticated technical health systems with relatively low hurdles for a preliminary admission into the DiGA directory."

Even though digital medical devices such as DiGAs run into the same limitation as telemedicine in that they do not replace the interaction with the doctor and direct treatment and are only a complementary measure, they offer tangible benefits for patients. They foster self-determination and increase flexibility as they enable disease self-management. This improves the quality of healthcare and patient well-being, while it reduces health care provider burden at the same time.

DiGAs support eh control of one's own health and an improvement in the self-management of chronic diseases. Unlike many other medical apps, their use and safety have been certified.
