Potential limits and risk of digitalization in public health will be a core topic of the High profile Research Area Health Sciences at the University of Bremen in coming years. A white paper was developed to support positioning in this dynamic research. The paper describes the Health Sciences viewpoint on core evaluation criteria for digital public health, identifies interfaces and approaches for interdisciplinary cooperation and discusses cross-cutting themes as well as demarcations with respect to digitalization in medicine (digital health). An abbreviated version of the white paper is presented for discussion.
