Communication The etymology of the word communication is from the Latin’s “communicare”, which means “make something common”, and the word has a multiplicity of meanings and is used in different contexts.17 In healthcare there are many types of communication depending on in which context communication is performed and on whether communication is performed between personnel and patients or between different personnel. In the present thesis, the focus was on studying the communication between healthcare personnel. Barriers to communication are described as both internal (individual) and external (environment). The internal barriers are described as language difference, culture, motivation, expectations, past experiences, prejudice, status, emotion/moods, deafness, and voice level. The external barriers are described as noise, interference and distraction, separation in location, time, and lack of visual cues (e.g., body language, gestures, and facial expressions).18 An error of communication is defined as “missing or wrong information exchange or misinterpretation or misunderstanding”.19 (p. 114)
