OBJECTIVE Explore how partners are involved in treatment-related decision-making within triadic clinical encounters. METHODS Studies were identified via database searches and reference lists. One author assessed eligibility of studies, which were verified by an additional co-author. Data were extracted by one author and cross-checked for accuracy by a second. Quality of articles was assessed using Qualsyst. Retrieved studies were categorised by one author, and agreed through discussion. RESULTS From 2442 records, 14 studies were included and categorised as: (1) Descriptions of partner role and behaviour; (2) Role intentions of partners; (3) Relationship between partner and patient behaviour; (4) HCP-Partner interactions. CONCLUSION Partners are often involved in triadic clinical consultations that have implications for treatment-related decision making. Most studies offered general descriptions but lacked detailed investigation of communicative processes in triads and how these may operate with partners vs. other companions. PRACTICE IMPLICATIONS Existing studies lack detailed investigation through direct observation of the processes of partner involvement. Research in other areas of clinical communication suggests that future interventions could be informed by attention to the following areas: partner behaviour vs. other companion types in triads; relationships between partner involvement and decision-making processes; partner involvement in triads vs. other groups (e.g. quadratic).
