Collaborative team-based practice can achieve all four components of the quadruple aim. But teamwork in health care has an identity crisis. Health care professionals refer to their teams as ‘‘multidisciplinary,’’ ‘‘interdisciplinary,’’ ‘‘interprofessional,’’ or the newest phrase, ‘‘transprofessional.’’ These terms are often used interchangeably and indiscriminately. According to the World Health Organization, this lack of clear taxonomy is seen as a major barrier to integrating effective collaborative practice into education and clinical settings. Using confusing terminology heightens the risk of reinforcing traditional hierarchies and power structures that can create a toxic environment that limits team effectiveness to address the needs of the whole patient.
