Modifying NICE's Approach to Equity Weighting

Area of Science:

• Health Technology Assessment
• Health Economics
• Public Health Policy

Background:

• The National Institute for Health and Care Excellence (NICE) is consulting on its methods for evaluating new health technologies.
• Equity weighting is a common practice in health technology assessment (HTA) to adjust cost-effectiveness thresholds for specific populations.
• NICE's current approach to equity weighting is under scrutiny for its impact on population health and equity.

Purpose of the Study:

• To analyze the impact of NICE's current equity weighting methods on population health and equity.
• To evaluate alternative approaches for incorporating equity considerations into NICE's HTA processes.
• To provide recommendations for NICE's future use of modifiers in decision-making.

Main Methods:

• Analysis of NICE's current equity weighting methodology.
• Evaluation of two proposed modifications to the existing approach.
• Assessment of a standard 'net benefit' approach as an alternative.

Main Results:

• NICE's current equity weighting approach demonstrably reduces both population health and equity-weighted population health.
• Modifying the current approach presents specific challenges.
• A standard 'net benefit' approach offers greater transparency and avoids the issues associated with modifying the current system.

Conclusions:

• NICE's current equity weighting practices appear to contradict its core principles.
• Adopting a standard 'net benefit' approach is the most desirable option for transparent and effective HTA.
• Balancing equity considerations with cost-effectiveness thresholds is crucial, especially given NICE's obligations under the 2019 Voluntary Scheme.
