BACKGROUND: Telehealth is viewed as a major strategy to address the increasing demand for care and a shrinking care professional population. However, most nurses are not trained or are insufficiently trained to use these technologies effectively. Therefore, the potential of telehealth fails to reach full utilization. A better understanding of nursing telehealth entrustable professional activities (NT-EPAs) and the required competencies can contribute to the development of nursing telehealth education. METHOD: In a four-round Delphi-study, a panel of experts discussed which NT-EPAs are relevant for nurses and which competencies nurses need to possess to execute these activities effectively. The 51 experts, including nurses, nursing faculty, clients and technicians all familiar with telehealth, were asked to select items from a list of 52 competencies based on the literature and on a previous study. Additionally, the panelists could add competencies based on their experience in practice. The threshold used for consensus was set at 80%. RESULTS: Consensus was achieved on the importance of fourteen NT-EPAs, requiring one or more of the following core competencies; coaching skills, the ability to combine clinical experience with telehealth, communication skills, clinical knowledge, ethical awareness, and a supportive attitude. Each NT-EPA requires a specific set of competencies (at least ten). In total, 52 competencies were identified as essential in telehealth. DISCUSSION/CONCLUSION: Many competencies for telehealth, including clinical knowledge and communication skills, are not novel competencies. They are fundamental to nursing care as a whole and therefore are also indispensable for telehealth. Additionally, the fourteen NT-EPAs appeared to require additional subject specific competencies, such as the ability to put patients at ease when they feel insecure about using technology. The NT-EPAs and related competencies presented in this study can be used by nursing schools that are considering including or expanding telehealth education in their curriculum.
