1
Ranking of implementability of 3 recommendations by experts at COGS
Validity of the construct of implementability
Consistent ranking
2
Guideline review with early GLIA versions
To refine GLIA
Demonstrate feasibility of measurement of implementability
3
Expert review of GLIA items and dimensions by HL7 experts
Content validity of GLIA
GLIA items rated generally as relevant and clear. Two new items were added, definitions were clarified, and explanatory material was added.
4
Review of the recommendations ranked in Step 1
