Before Round 1 of the Modified Delphi process, all NAP members received the following description of methodology:
- Through structured responses, NAP members are requested to indicate their degree of support for draft recommendations. An "N/A" response offers an option for NAP members not able to give an opinion about a specific statement.
- The evidence grade for recommendations lacking Grade A or Grade B evidence will be considered Grade C if NAP reaches consensus.
- The definition of consensus for this Modified Delphi process is:
80% of National Advisory Panel respondents indicate that they Agree or Strongly Agree with the statement “I support this recommendation.”
- Results from the Modified Delphi process will identify:
- recommendations the NAP supports by consensus
- recommendations that require further consultation with NAP.
- Following NOUGG analysis of all NAP replies, each respondent will receive a comparison of their own individual feedback and the aggregate NAP responses.
- The Modified Delphi process will be used in subsequent guideline rounds as required.
- After Round 2 of the Modified Delphi process, recommendations based on Grade C evidence only and failing to reach consensus will be eliminated. However, recommendations based on Grade A and/or B evidence that fail to achieve consensus will undergo further revision for consideration by NAP in a third round.
