Communication can be thought of as a message that is sent, received, and understood. Each discipline of the health profession has its own jargon and means of expressing ideas in shorthand. These separate forms of communicating are effective among those of the same background but are often at the root of misunderstandings between professional groups. This article reviews communication theory and traces the difficulties created when inter-disciplinary teams of healthcare try to work together and communicate. As multi-disciplinary teams are increasingly dealing with the complex problems of today's healthcare system, clear communication and understanding has never been more important. If educators could assist in creating an understanding of vocabulary used for decision processes, communication could improve. The authors of this study performed a multi-stage Delphi survey that grouped terms used by administrators and clinicians and produced a lexicon of corresponding terms. An expert panel then reviewed and modified the list. The result is a lexicon that can be useful to assist clinicians and administrators to communicate with each other. By utilizing clinical terminology, or vice versa, instead of management or clinical jargon, some of the translation done by administration or clinicians could be reduced. Examples of how the lexicon can be utilized are provided in the article. This includes using it in health administration education to demonstrate the variances in clinical/managerial terms. It could also be provided as a primer to physicians, nurses, and other health professionals who assume administrative positions to enhance their communication with administrators.
