Impact of hospitalists' social identities on perceptions of teamwork.

Interprofessional teamwork provides unique opportunities for improving patient care. This study used Social Identity Theory as a conceptual framework to characterize the relationships between the social identities of pediatric hospitalists and their perceptions of interprofessional teamwork. We used qualitative methods including free-listing and semi-structured interviews to examine these relationships. We identified five key themes: (a) Pediatric hospitalists' identities fall along a spectrum ranging from profession-centered to team-centered; (b) Familiarity is conducive to formation of team identity; (c) Co-creation of a shared vision and practice of creating shared mental models strengthens sense of team; (d) Institutional culture acts as both a facilitator for and barrier to formation of team identity; (e) High-functioning teams often epitomize the concept of "flexible leadership." We conclude that Social Identity Theory can be a useful theoretical lens for examining interprofessional teamwork in healthcare settings, including among pediatric hospitalists.
