Data4Life supports the CharitĂ© – UniversitĂ€tsmedizin Berlin in developing a corona app "CovApp"

Technology helps speed up decision-making for anyone worried about a coronavirus infection.

Berlin, March 18, 2020. The coronavirus SARS-CoV-2 continues to spread in Berlin. Uncertainty among the population is increasing, leading more and more people to seek out doctors and hospitals for testing. The university hospital in Berlin, together with the nonprofit organization Data4Life in Potsdam, has made a meaningful contribution to organizing medical care in Berlin by developing the CovApp.

With the CovApp, everyone can fill out a questionnaire from home to decide if they should go to a CharitĂ© examination center for people suspected of having coronavirus or if another contact center is appropriate. The questionnaire is anonymous and is edited and saved directly on the user’s end device. For those who fill out the CovApp questionnaire and visit a CharitĂ© examination center, the CovApp supports their doctors during consultation and helps shorten the waiting period for all arrivals. Additionally, all answers from the questionnaire can be transferred efficiently to the hospital using a QR code. Implementing a QR code for sharing relevant medical information increases efficiency on site, making it possible for more people to get tested daily and receive care in the outpatient clinic.

“We have set out to support the healthcare system with technological solutions and offer people solutions to improve their health and quality of life in the long term,” explains Christian Weiß, CEO of Data4Life, showing the organization’s commitment. “As a nonprofit organization, we have a privilege and duty in times like these to help all relevant actors with our resources and know-how,” Weiß continues.

“By implementing the CovApp, we’re contributing to the protection of our patients and employees. Due to high demand in our examination center, it’s of the utmost importance that we do not endanger people whose symptoms do not indicate SARS-CoV-2, and inversely, that we can swab patients who do need testing as quickly as possible,” explains Prof. Dr. Ulrich Frei, Chief Medical Officer at the CharitĂ©.

The CharitĂ© and Data4Life are receiving legal counsel on this project from Dr. Ulrich Grau and Lisa Zerbe at D+B RechtsanwĂ€lte. Dr. Ulrich Grau, partner at the law firm D+B RechtsanwĂ€lte, adds: “The quickly developed app is not designed to provide a diagnosis. In this crisis situation, however, the app can contribute to optimizing procedures in medical care for the population.”

Data4Life is a nonprofit organization dedicated to improving healthcare and research with technology and data. Data4Life supports actors in the health system, like the Charité, with technological know-how and resources, using technological solutions to make healthcare more efficient. In cooperation with strong partners such as the Hasso Plattner Institute for Digital Engineering gGmbH and financed by the Hasso Plattner Foundation, Data4Life has been successfully working on fast and stable technological solutions for the health sector since 2018. These solutions are currently being applied in this collaboration with the Charité.
