A Comparison of National Guidelines for Network Meta-Analysis

Area of Science:

• Health Economics
• Biostatistics
• Evidence Synthesis

Background:

• Network meta-analysis (NMA) is crucial for comparing interventions and informing reimbursement decisions.
• Reimbursement agencies increasingly rely on sophisticated NMA techniques for evidence assessment.
• NMA provides essential comparative efficacy estimates when direct evidence is limited.

Purpose of the Study:

• To compile a comprehensive set of NMA requirements from national guidelines.
• To enable a single NMA to meet the specifications of various reimbursement bodies.
• To streamline the process of submitting NMA evidence for global reimbursement.

Main Methods:

• Systematic review of published and draft guidelines from reimbursement and health technology appraisal agencies.
• Examination of stipulations for NMA conduct, design, bias reduction, and validity measures.
• Inclusion of guidelines from 41 countries, with 13 country-specific documents and one from the European Network of Health Technology Assessment.

Main Results:

• Guidelines from 13 countries and the European Network of Health Technology Assessment were analyzed.
• The aggregated guidelines do not present mutually prohibitive requirements for NMA.
• A unified approach to NMA conduct is feasible for submission to multiple national jurisdictions.

Conclusions:

• It is possible to conduct a single network meta-analysis that satisfies the requirements of numerous national reimbursement bodies.
• This harmonized approach simplifies evidence submission for comparative effectiveness.
• The findings facilitate broader acceptance of NMA evidence in global health technology assessment.
