Specifically, they developed an approach—named after the Ancient Greek Oracle of Delphi, who could predict the future—which promoted anonymity and avoided direct confrontation between experts, so that the methods employed “…appear to be more conducive to independent thought on the part of the experts and to aid them in the gradual formation of a considered opinion”.1 Though the original Delphi study was linked to the defence industry, the technique has spread to other research areas, including nursing.2 Characteristics of Delphi studies As with all research methods, the Delphi technique has evolved since it was first reported on in the 1960s. ...participants are able to see the results of previous rounds—including their own responses—allowing them to reflect on the views of others and reposition their own opinions accordingly.2 This also gives them the opportunity to consider and feedback on what they perceive to be the strengths and weaknesses of other’s responses. ...the findings of each round are always shared with the broader group anonymously. Analysis of this scoring then allowed for consensus conclusions on the top 10 human factors that contributed to nursing errors (with fatigue, heavy workload and communication problems the top three).3 In another example, nurse practitioners (NPs) were recruited to participate in a Delphi study to achieve consensus related to NP advance care planning competencies.
