A triangle that may work well: Looking through the angles of a three-way exchange in cancer medical encounters

Following a discourse analysis approach this study examines triadic encounters of nine medical consultations carried out in an outpatient cancer clinic in Santiago, Chile involving an oncologist, a patient and a patient’s companion. Consultations are fully transcribed and analysed to understand the participatory roles patients’ companions play in the medical exchanges. In addition, the type of linguistic functions associated with each role and the advantages or downsides of companions’ involvement in the encounters are also investigated. The analysis reveals seven prominent roles that companions may engage in during the visits. These are studied in detail. The results show that although companions may not always provide information that is consistent with the patients’ views, they can be of great help. Relieving the patients of many daunting tasks, monitoring their well-being, establishing a partnership and bringing vital information to the clinic are instances where the controlling power that some may exercise in the medical encounter can be outweighed.
