Laut Bundesinstitut für Bau-, Stadt- und Raumforschung sind in Deutschland 70 % der Fläche als ländlich ausgewiesen, rund 30 % der deutschen Bevölkerung lebt in diesem Raum. Der Anteil an älteren Menschen ist hier deutlich höher als im städtischen Raum und damit auch die Prävalenzen vieler chronischer Erkrankungen. Gleichzeitig steht jedoch die Sic...

Zusammenfassung Auch während Pandemien müssen die Blutspendedienste kontinuierlich BlutspenderInnen rekrutieren, um die Versorgung mit Blutprodukten zu gewährleisten. Während im Anschluss an andere Katastrophen wie Erdbeben oder Terroranschlägen die Spendebereitschaft meist sprunghaft ansteigt, zeigte sich in der Vergangenheit bei beginnenden Pande...

In empirischen Studien zum Rückkehrverhalten von Erstspendern konnten Erfolgsfaktoren einer gelingend...

Altruism is often reported by repeat donors to be their major motivation. It is, however, unclear whether altruism is relevant for both non-remunerated and remunerated blood donors. To describe donor motivation of non-remunerated and remunerated German first-time donors as well as donor return, we conducted a retrospective analysis of two donor sur...
