How to use the Delphi method to aid in decision making and build consensus in pharmacy education

As pharmacy educators, we often encounter situations such as designing new curricula or establishing shared values for an organization that may be ambiguous or controversial. To generate effective solutions, it is often necessary to build group consensus with key stakeholders. The purpose of this paper is to describe and provide recommendations for using the Delphi method, a process for facilitating discussions and aiding in decision making. An overview of the Delphi method, including its multiple variations, is presented. Steps necessary to complete a Delphi study (building a protocol, developing a research question, defining panelists and panel size, piloting the protocol, round one item creation and analysis, round two and beyond, consensus, increasing clarity, and reporting) is described. Practical recommendations are provided to support use the Delphi method to build consensus in research. These recommendations include: (1) clarify the purpose of the Delphi, (2) ensure the research questions are grounded in the literature and are relevant, (3) carefully consider panelist processes, (4) determine any definitions that should be given to or developed by panelists, (5) determine methods for enhancing clarity, and (6) employ methods to reduce attrition. The Delphi method provides a systematic approach to generating consensus in pharmacy education for commonly encountered situations such as committee meetings, research studies, faculty retreats, classroom activities, and lab meetings.
