Integrating equity and productivity in health evaluation

Area of Science:

• Health economics
• Outcome measurement
• Public health policy

Background:

• Traditional health outcome measures like QALYs (Quality-Adjusted Life Years) do not fully capture equity or productivity.
• Existing extensions (PALYs, PQALYs) offer partial solutions but lack a unified approach.
• Assessing interventions requires methods that consider both health gains and economic productivity.

Purpose of the Study:

• To develop a unified framework for health outcome evaluation that integrates equity and productivity.
• To extend existing evaluation functions to incorporate both equity- and productivity-sensitive conditions.
• To provide a coherent foundation for assessing interventions where health and productive capacity are interdependent.

Main Methods:

• Developed a novel class of evaluation functions.
• Incorporated normative criteria such as scale independence and Pigou-Dalton transfer principles.
• Derived tractable power-form representations for the evaluation functions.

Main Results:

• Introduced a broader class of evaluation functions beyond QALYs, PALYs, and PQALYs.
• Established power-form representations based on specified normative criteria.
• Demonstrated a framework that balances equity and efficiency in outcome evaluation.

Conclusions:

• The proposed framework offers a coherent method for evaluating health interventions considering both equity and productivity.
• This approach provides a more comprehensive assessment than traditional measures alone.
• It is particularly valuable for analyzing interventions affecting both health status and economic productivity.
