We present analysis of admission/discharge data from insurance provider for Saxony and Thuringia (Germany) for years 2010-2016. Study of such data is necessary to derive a structure of healthcare system transfer network, as no patients' transfer data are available. Hospital network is a basis for simulation of multidrug-resistant bacteriae spread allowing to study the effectiveness of disease-control strategies. In this paper, the properties of the dataset under consideration are presented and discussed. Moreover, the resulting interhospital network structure is analyzed.
