Constant change in the health care delivery system requires nurses to be flexible in their role. Flexibility is the key to success during periods of change. Professional nurses need to open themselves up to a variety of ideas in order to arrive at a perspective of health care that enhances the practice of nursing. Fundamental to this concept is the ability to work in teams. No single individual can know everything that is required for practice today, and so the team becomes the focus. The Institute of Medicine emphasizes that teams improve skills, communication, participation, and effectiveness and includes use of inter-professional teams as one of the key five core health care professions competencies. Teams play a critical role in ensuring integration and coordination of care for patients.
