A new tool, the Scientific, Transparent and Applicable Rankings (STAR) tool, effectively evaluates and ranks clinical practice guidelines. It demonstrates strong reliability, validity, and usability for comprehensive guideline assessment.
Area of Science:
- Health Sciences
- Medical Informatics
- Evidence-Based Medicine
Background:
- Clinical practice guidelines (CPGs) are crucial for healthcare decision-making.
- A need exists for standardized tools to evaluate CPG quality and applicability.
- Existing evaluation methods may lack comprehensiveness or practical usability.
Purpose of the Study:
- To develop and validate the Scientific, Transparent and Applicable Rankings (STAR) tool for evaluating and ranking CPGs.
- To assess the reliability, validity, and usability of the STAR tool.
- To provide a robust instrument for enhancing the quality of healthcare guidelines.
Main Methods:
- A multidisciplinary working group developed the STAR tool using scoping review, Delphi methods, and hierarchical analysis.
- The study evaluated intrinsic and interrater reliability, content and criterion validity, and usability.
- Evaluations involved methodological and clinical experts assessing STAR's performance.
Main Results:
- The STAR tool comprises 39 items across 11 domains.
- High reliability was observed: Cronbach's α for intrinsic reliability (0.588) and Cohen's kappa for interrater reliability (0.774 methodological, 0.618 clinical).
- Excellent validity (content validity index 0.905, criterion validity Pearson's r 0.885) and usability (mean score 4.6, 20 min/guideline) were confirmed.
Conclusions:
- The STAR tool is a reliable, valid, and efficient instrument for comprehensive CPG evaluation and ranking.
- STAR facilitates objective assessment and ranking of clinical practice guidelines.
- The tool supports evidence-based practice by improving guideline quality.
