Digital health literacy in Germany: current status, concepts, and challenges

Abstract

A key prerequisite for the successful digital transformation of the healthcare system is a well-developed level of digital health literacy (DHL) among the population. DHL is the ability to deal with health-relevant digital information and information options with the aim of promoting and maintaining health and well-being for oneself and one’s environment. This article examines the discussions about digital health literacy, the existing studies and measurement tools used in them, the data situation in Germany, and current challenges. DHL consists of various sub-competencies that reflect current digital information behavior, opportunities, and risks. The data situation is very heterogeneous due to different study designs and instruments, which limits the informative value. Two representative studies, HLS-Ger‑2 by Bielefeld University and the study by AOK Rheinland/Hamburg and the Leibniz-WissenschaftsCampus, both indicate a high proportion of people with low DHL despite different methods. Both nationally and internationally, DHL is subject to a social gradient and is associated with educational level, social status, financial deprivation, and age. According to the current empirical data, the acquisition of DHL in Germany is still insufficient, so there is a great need for action. The necessary legal framework conditions have been established, but there is still a lack of reliable and financial resources, as well as a solid data basis on DHL at population level. This is essential to identify vulnerability factors and to prepare and evaluate the implementation of measures. In addition, there is a need for an in-depth conceptual discussion on DHL that builds on the established health literacy concept and addresses the emerging health-related infodemic and its consequences for DHL.
