Core Tip
Core Tip: There are no standard quality parameters to evaluate Delphi methods in healthcare research. Delphi methods’ vital elements include anonymity, iteration, controlled feedback, and statistical stability of consensus. Published studies have used modified versions of Delphi, and details on methods like expert panel selection, defining consensus, or closing criteria for Delphi rounds are not explicit. We suggest quality assessment tools for readers and researchers for a systematic assessment of Delphi studies.
