High-quality compression therapy (CT) trials require specific methodological parameters for chronic venous disease and lymphedema. Combining randomized controlled trials (RCTs) with real-world evidence (RWE) offers a comprehensive understanding of CT effectiveness and outcomes.
Area of Science:
- Vascular Medicine
- Clinical Trial Methodology
- Evidence-Based Practice
Background:
- Compression therapy (CT) is a common treatment for chronic venous disease (CVD), lymphedema, and lipedema.
- Evidence supporting CT effectiveness is robust only in specific clinical scenarios.
- Methodological rigor in CT trials is crucial for reliable results.
Purpose of the Study:
- To outline essential methodological parameters for high-quality scientific trials on compression therapy.
- To provide recommendations for improving the design and reporting of CT randomized controlled trials (RCTs).
Main Methods:
- A preliminary list of methodological flaws and essential parameters for CT trials was drafted by the International Compression Club (ICC) chairman.
- The list was refined through comments and suggestions from ICC board members.
- A consensus meeting with professionals in May 2024 in London finalized the recommendations.
Main Results:
- The ICC recommends reporting specific parameters in CT RCTs: patient selection, sample size, disease classification, CT modality details, and adherence.
- Tailored recommendations for specific conditions and standardized quality-of-life (QoL) tools are emphasized.
- Real-world evidence (RWE) is proposed to complement RCTs by offering insights into routine practice, safety, compliance, and cost-effectiveness.
Conclusions:
- Combining RCTs and RWE provides a holistic evaluation of compression therapy.
- RCTs demonstrate effectiveness in controlled settings, while RWE reflects real-world compliance and economic outcomes.
- This integrated approach addresses knowledge gaps and guides optimal CT utilization in clinical practice.
