The study conducted by Einav and colleagues addresses a work-system factor that is perhaps one of the most difficult to improve, namely, teamwork. Indeed, the multidisciplinary nature of teams in many health-care settings poses a challenge to those aiming to optimize performance and improve patient care.4 In particular, teamwork in health care can often involve collaboration among a myriad of health-care specialties, including attending physicians, residents, nurses, technicians, and other associated personnel. Team members are jointly responsible for patient care, yet at the same time they have a wide variety of different tasks to perform. Furthermore, different tasks and activities among the team may interfere with one another such that the conditions necessary for the successful execution of a task by one team member may hinder or delay the actions of others on the team. Compounding the problem is the fact that there are numerous forms of distraction and interruption within health-care settings that can interfere with a team's ability to effectively communicate and coordinate these activities. Therefore, it is often difficult for diverse health-care teams to develop familiarity, trust, and a common understanding of patient needs and then effectively coordinate their activities to achieve safe and effective patient care. Not surprising, the Joint Commission on Health Care Quality and Safety4 reports “communication” as the number one root cause (65%) of reported sentinel events.
