The aim of this paper is to understand how the role of an mHealth artifact is played out in home care settings. An mHealth artifact, in terms of a mobile app (primarily for tablets) was tested to see how the quality of home care work practice was enhanced and changed. The research question the paper explores is: In what ways is an mHealth artifact re-shaping a home care practice and how does this affect the interaction between the caregivers and the elderly and learning opportunities for the caregivers? This research has an action research approach and it was conducted in a home care organization in a Swedish municipality. The data was collected through semi-structured interviews and observations that were conducted during home visits. Concepts of boundary objects were used to analyze and distinguish interactions and conversations with the designed mHealth artifact. Using the mHealth artifact as a boundary object in the caring situation triggered a caring conversation between the caregivers and the elderly. They grew closer and started having deeper conversations. The shift in responsibility, due to new processes enabled the caregiver to stay for a longer time putting the correct care in centrum. The findings reveal that views of the mHealth artifact as a designated boundary object as well as a boundary object-in-use must co-exist in order to understand the emergent properties situated in a technology mediated caring conversation. The study provides qualitative descriptions from early tests of mHealth applications for home care, an emerging area of concern for both research and practice. It focuses on the interactional and organizational values generated from the actual use of the designed mobile application.
