Making the GRADE: CHEST Updates Its Methodology.

Area of Science:

• Medical Guidelines
• Evidence-Based Practice
• Clinical Decision Making

Background:

• The American College of Chest Physicians (CHEST) has a long history of developing evidence-based clinical practice guidelines.
• CHEST previously utilized a modified Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system since 2006.
• Evolving guideline models and collaborations necessitated methodological improvements.

Purpose of the Study:

• To transition CHEST's guideline development methodology to the standard GRADE approach.
• To enhance consistency and clarity in CHEST's evidence-based clinical practice guidelines.
• To align CHEST's methods with those of other leading organizations.

Main Methods:

• Adoption of the standard GRADE method for rating evidence certainty.
• Application of the standard GRADE approach for grading recommendations in all CHEST guidelines.
• Implementation across new and updated guidelines.

Main Results:

• The standard GRADE approach will be applied to all CHEST guidelines.
• Methodology will become more consistent with international standards.
• Recommendations are expected to be more explicit and easier to understand.

Conclusions:

• CHEST's transition to the standard GRADE method signifies a commitment to rigorous and transparent guideline development.
• This change will improve the alignment of evidence synthesis and the clarity of recommendations.
• The updated methodology supports the delivery of high-quality, evidence-based clinical guidance.
