Developing clinical guidelines: how much rigour is required?

Area of Science:

• Healthcare Quality Improvement
• Clinical Practice Guidelines
• Evidence-Based Medicine

Background:

• Clinical guidelines are crucial for standardizing healthcare and reducing practice variations.
• National bodies cannot meet the demand for guidance on all medical topics.
• Fewer resources exist for locally produced or specialty group guidelines, necessitating a balance between pragmatism and rigor.

Purpose of the Study:

• To introduce key concepts in developing clinical guidelines.
• To provide suggestions for those interested in creating their own guidelines.
• To highlight challenges in generating high-quality clinical guidance.

Main Methods:

• The paper discusses the general principles of guideline development.
• An illustrative case study (Box 1) details the process and challenges faced by a local service.
• The case study involved identifying clinical questions, searching PubMed, and formulating recommendations, including consensus for areas lacking evidence.

Main Results:

• A local Guideline Development Group successfully created a guideline for PAVING syndrome management.
• The guideline development involved evidence searching and consensus-based recommendations.
• The guideline was rejected for endorsement by a professional college due to methodological concerns.

Conclusions:

• Developing rigorous clinical guidelines presents significant challenges, especially for local or specialty groups.
• Methodological rigor is essential for the acceptance and endorsement of clinical guidelines.
• Clearer guidance is needed from professional bodies on developing acceptable clinical guidelines.
