Purpose: There is a disconnect between how healthcare teams commonly are trained and how they act in reality. The purpose with this paper was to present a learning activity that prepares healthcare students to authentic teamwork where team members are fluent and move between different localities, and to explore how this setting affects learning.Methods: A learning activity Call the On-Call consisting of two elements, workplace team training where team members are separated into different locations, and a telephone communication exercise, was created. A case study approach using mixed methods was adopted to explore medical-, nurse-, physiotherapy- and occupational therapy students and supervisor perspectives of the effects of the learning activity. Data collection involved surveys, notes from reflection sessions, a focus group interview, and field observations. Thematic analysis was applied for qualitative data and descriptive statistics for quantitative data. The sociocultural learning theory, social capital theory, was used to conceptualize and analyse the findings.Results: The majority of the students (n=198) perceived that the learning activity developed their interprofessional and professional competence, but to a varying degree. Especially nursing students found value in the learning activity, above all due to increased confidence in calling a doctor. Physio- and occupational therapy students lacked the opportunity to be active during the telephone exercise, however, they described how it increased their interprofessional competence. Authenticity was highlighted as the key strength of the learning activity from all professions. Concerns that team building would suffer as a result of splitting the student team proved unfounded.Conclusion: The learning activity created new opportunities for students to reflect on interprofessional collaboration. Constant physical proximity during training is not essential for effective healthcare team building. Splitting the student team during training may in fact enhance interprofessional learning and lead to progression in interprofessional communication.
