The objective of GLIA is to provide a tool for the appraisal of the implementability of clinical guidelines. Implementability refers to a set of guideline characteristics that predict potential challenges to effective implementation. In addition to a series of questions that inquire about global aspects of a guideline's implementability, the instrument explores the following dimensions of individual recommendations:

• Executability
• Decidability
• Validity
• Flexibility
• Effect On Process Of Care
• Measurability
• Novelty/Innovation
• Computability

In 2011 we revised the GLIA instrument creating GLIA 2.0 based on user feedback. The revised instrument clarifies several questions, reorders the dimensions for a more logical flow, and streamlines the appraisal process.

A discussion of the original development of GLIA has been published in BMC Medical Informatics and Decision Making at The GuideLine Implementability Appraisal (GLIA): development of an instrument to identify obstacles to guideline implementation.
