ObjectiveLittle is known about which attributes the patients need when they wish to maximise their capability to partner safely in healthcare. We aimed to identify these attributes from the perspective of key opinion leaders.DesignDelphi study involving indirect group interaction through a structured two-round survey.SettingInternational electronic survey.Participants11 (65%) of the 17 invited internationally recognised experts on patient safety completed the study.Outcome measures50 patient attributes were rated by the Delphi panel for their ability to contribute maximally to safe health care.ResultsThe panellists agreed that 13 attributes are important for patients who want to maximise the role of safe partners. These domains relate to: autonomy, awareness, conscientiousness, knowledge, rationality, responsiveness and vigilance; for example, important attributes of autonomy include the ability to speak up, freedom to act and ability to act independently. Spanning seven domains, the attributes emphasise intellectual attributes and, to a lesser extent, moral attributes.ConclusionsWhereas current safety discourses emphasise attributes of professionals, this study identified the patient attributes which key opinion leaders believe can maximise the capability of patients to partner safely in healthcare. Further research is needed that asks patients about the attributes they believe are most important.
