Delphi process. Approval process to the 3 classes of statements is reported: agreement by ≥75% of the panelists was requested. Rephrased, but previously approved, statements were accepted when at least 60% of the panelists agreed on the final phrasing. “Good clinical practice statements” involved actionable recommendations, which were expected to lead to a relevant health care practice improvement and were supported by direct or well-documented and explicit indirect evidence. Rather, “background statements” include nonactionable descriptive assertions or standardized practice actions. Finally, “research statements” include a list of actionable (or nonactionable) suggestions that are not sufficiently supported by evidence or cannot yet be estimated to lead to a large healthcare improvement.
