Interprofessional training wards are designed to train students’ team and communication competences. Such wards are generally highly valued clinical placements by undergraduate students; however, evidence in the literature suggests that medical students experience a lack of profession-specific tasks on these wards. Moreover, students lack structured training in the complexities of everyday communication where different health professions rarely are present together in stable teams. This paper reviews one strategy to train students in interprofessional communication while letting students perform profession-specific tasks. A qualitative study with ethnographically-collected data was conducted among three interprofessional student teams over three two-week periods, mixing field observations (75 h), interviews (n = 16), and field notes (45 pages). The findings show that students gained insights into new aspects of their professional roles and an appreciation of clear and open interprofessional communication over the telephone. Learning was facilitated through being confronted with new situations and discussing these experiences with each other over time. Call the On-Call as a pedagogic activity provided not just medical students, but also nursing students with new types of profession-specific tasks on the interprofessional training ward.
