BackgroundThe decision partner concept emerged to describe someone who contributes to healthcare decision-making with a patient. There is a need for greater precision and consensus surrounding its conceptual definition and use in broader populations.ObjectiveTo define and describe the decision partner concept within the context of healthcare decision-making.DesignA concept analysis.Data SourcesWe searched the following databases for articles published between 1990-2017: PsychINFO, PubMed, Embase, and CINAHL. We included qualitative, quantitative, or mixed methods studies that used the term decision partner in the context of healthcare decision-making.MethodsWe applied the Walker and Avant method to identify the antecedents, attributes, related concepts, consequences, and empirical referents of the concept, with major themes identified.ResultsFrom the 112 articles included in this concept analysis, 6 defining attributes of decision partner were identified: (1) has a relationship with the patient, (2) demonstrates a willingness to participate in decision-making, (3) articulates a clear understanding of both the patient's health condition and the decisions that must be made, (4) demonstrates decision-making self-efficacy; (5) exemplifies an emotional capacity to participate in decision-making, and (6) willing to fulfill several supportive roles including patient advocate and the "hub of information".ConclusionsA unifying definition and discussion of the decision partner concept has been developed. Our findings: (1) offer insights into refining the concept across various diseases and healthcare encounters, (2) contribute to developing theoretical models and empirical research to refine antecedents, attributes, consequences, (3) serve as a foundation to develop instruments to measure the concept and (4) highlight the need to design interventions that include and support decision partners in healthcare decision-making.Copyright © 2019 Elsevier Ltd.
