This study investigates assistant nurses’ views on and needs for orientation to care robot use in three European countries. The use of care robots is gradually being incorporated into welfare services. Orientation to care robot use (in short, introduction to the use of the care robot technology) has thus become a key issue for care services. A survey was sent to assistant nurses in Finland, Germany, and Sweden, to which 302 participants responded (Finland n = 117; Germany n = 73; Sweden n = 112). Only 11.3% of assistant nurses had experience of giving orientation to care robot use to older adults or colleagues, but over 50% were willing to do so. Those with experience of using care robots should take part in orientation. Orientation to care robot use should be seen as part of care management and an issue that may affect the whole organisation. Management should, firstly, allow assistant nurses to get to know care robots by offering information, and secondly, consider with the assistant nurses the ways care robots can change their work and the implications of this change. Emphasising the social factors and practical orientation to care robot use extends the previous theories and perspectives of technology acceptance, adoption and diffusion.
