Summary
Guideline Element Model (GEM) constructs effectively analyzed and categorized guideline content, though element application varied among users. Further tool development could enhance its translation capabilities.
Area of Science:
- Medical Informatics
- Health Services Research
- Clinical Guideline Development
Background:
- Clinical guidelines are crucial for evidence-based practice.
- Analyzing and categorizing guideline content presents challenges.
- A structured approach is needed to understand guideline components.
Purpose of the Study:
- To describe the application of the Guideline Element Model (GEM) for analyzing and categorizing clinical guideline content.
- To evaluate the usability and comprehensiveness of GEM constructs.
Main Methods:
- GEM constructs were applied to the American Academy of Pediatrics (AAP) guideline on neurodiagnostic evaluation of febrile seizures.
- Eight subjects used a hierarchical template to mark up guideline content across various categories.
- Subjects were surveyed on the usability of the GEM model.
Main Results:
- Eight subjects utilized between 46 and 149 elements to model the guideline content, with notable variation in application.
- The number of elements used correlated with the time required for the task.
- Subjects found GEM straightforward to apply in most categories and sufficiently comprehensive for modeling information content.
Conclusions:
- GEM constructs demonstrated the ability to model the content of a clinical guideline.
- Enhancements to editing tools are recommended to improve the translation of GEM application.
