The Delphi and nominal group techniques in health services research
Abstract
This review examines two methodologies that are being increasingly used in health services research (HSR): the Delphi and nominal group techniques. The Delphi is a survey technique for decision making among isolated respondents while the nominal group technique (NGT) is a highly controlled small group process for the generation of ideas. Typical applications of the techniques are for the development of consensus guidelines or standards in areas where research based evidence is absent or inconclusive. We discuss methodological issues associated with these techniques, namely, sample size and composition, response rates, anonymity, feedback and consensus, and reliability and validity. We also illustrate the range of applications of the techniques in HSR, including pharmacy practice. Although not widely used to date, both methodologies are potentially valuable additions to the practice researcher's toolbox.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
