As a tool for building consensus among groups, Delphi technique has been widely used in healthcare research which is appropriate for clinical questions where quantitative methods are unlikely to yield results that can be successfully implemented in practice. Researchers in palliative care developed standards for conducting and reporting Delphi studies (CREDES). This paper introduces and interprets the specific content of CREDES standards, with a view to providing reference for the evaluation of Delphi research design quality and report transparency.
