EVIDEM Framework
The EVIDEM Framework is a structured method that helps decision-makers evaluate healthcare treatments by considering multiple factors—like clinical benefits, costs, ethical issues, and social impact—especially useful when assessing treatments for rare diseases. It supports fair and transparent decisions by balancing different values and uncertainties.
At a glance
Use when
Evaluating interventions with high uncertainty, ethical complexity, or special policy considerations—such as orphan drugs or treatments for rare diseases; when transparent, multi-stakeholder decision-making is needed; in contexts requiring explicit value-based trade-offs
Avoid when
Rapid, resource-limited assessments where simplicity is prioritized; when only clinical or economic data are required without broader value considerations; in settings without capacity for stakeholder engagement or MCDA methods
Inputs
Clinical evidence, economic data, disease-specific characteristics, stakeholder values, context-specific policies, ethical considerations, uncertainty estimates
Outputs
Structured value assessment scores, transparent trade-off analysis, context-adapted prioritization recommendations, quantitative and qualitative decision support
How it works
The EVIDEM Framework is a multicriteria decision analysis (MCDA) method designed for holistic value assessment of healthcare interventions. It includes criteria and subcriteria covering clinical, economic, ethical, and organizational domains. Adapted in this study for rare diseases, it incorporates enhanced subcriteria for disease severity, treatment outcomes, and economic consequences, along with negative scoring scales for comparative criteria. It enables integration of context-specific policies and population priorities into quantitative decision models, allowing explicit trade-offs between ethical principles such as equity, utilitarian benefit, and resource stewardship, while supporting uncertainty analysis.
- HTA domains
- Clinical Effectiveness, Costs & Economic Evaluation, Patient and Social Aspects
- Assumptions
- Decision-makers seek transparent, ethically informed, and context-sensitive evaluations; stakeholders can meaningfully contribute to value weighting; value is multidimensional and includes non-health outcomes and ethical principles
- Strengths
- Comprehensive integration of clinical, economic, ethical, and social criteria,Adaptable to specific contexts such as rare diseases,Enables explicit trade-offs between competing ethical values,Supports transparency and stakeholder involvement,Includes uncertainty analysis and context-specific policy integration
- Limitations
- Requires expert input and stakeholder engagement, which may be resource-intensive,Subjectivity in scoring and weighting despite structured methods,Complexity may limit ease of use in rapid assessments,Validation in real-world decision-making contexts may vary
