The Innovation Committee of the Federal Joint Committee (G-BA) is funding a study via the Innovation Fund to analyse the process of introducing the ePA for all . The aim is to gain insights into which important factors influence the success of such major digitalisation initiatives in the health care system. In this study, 100 practices and 10 hospitals in North Rhine-Westphalia are being scientifically monitored and surveyed at various times over a period of 1 1/2 years about their experiences with the ePA for all . The study will look at facilities that already took part in the accompanied piloting of the ePA for all in the first half of 2025, as well as facilities that are managing the introduction of the ePA for all independently and unaccompanied.

In addition, 600 AOK Rheinland/Hamburg policyholders will also be asked to take part in a survey on their experience of using the ePA for all .
