Ethics approval and consent to participate
: The local institutional review board stated, that for this study no submission to the ethics committee is necessary (Ethik-Kommission der Bayerischen Landesärztekammer, Mühlbaurstraße 16, 81677 München ; reference number: 2019-018 fm/h). The study was performed in accordance with the ethical standards laid down in the 1964 declaration of Helsinki and its later amendments. Informed consent of the patients or their relatives was obtained at least verbally during the initial hospital stay or during the telephone interview in the follow up because written consent was not always available in terms of the initial hospital stay or follow up. The local institutional review board approved this procedure and waived a patient informed consent, as the data is fully anonymized (Ethik-Kommission der Bayerischen Landesärztekammer, Mühlbaurstraße 16, 81677 München ; reference number: 2019-018 fm/h).
: Not Applicable.
: Monika Killer-Oberpfalzer is holding a research grant from Microvention Terumo unrelated to this study. Alexander Hammer, Frank Erbguth, Matthias Hohenhaus, Christian M. Hammer, Hannes Lücking, Markus Gesslein, Hans-Herbert Steiner and Hendrik Janssen declare no competing interests.
