Abstract
Effective interprofessional team function is integral to high-quality care in the intensive care unit (ICU). However, little is known about how familiarity develops among teams, which may be an important antecedent to effective team function and quality care. To examine team familiarity and how it impacts ICU team function and care, we conducted an ethnographic study in four ICUs (two medical ICUs, one mixed medical-surgical ICU, and one surgical ICU) in two community hospitals and one academic medical center. We conducted 57.5 h of observation, 26 shadowing experiences, and 26 interviews across the four ICUs sequentially. We used thematic analysis to examine familiarity among the team. We found that ICU team members become familiar with their team through interpersonal, relational interactions, which involved communication, time working together, social interactions, trust, and respect. Our findings underscore the relational aspect of effective teams and demonstrate that time working together, social interactions, communication, developing trust, and respect are pathways to familiarity and optimal team function. Leveraging unique and creative ways to enhance the relational aspects of ICU teams could be an area for future research and lead to improved ICU outcomes.
