A QALY-based societal health statistic for Canada, 1985

Area of Science:

• Health Economics
• Public Health Policy
• Biostatistics

Background:

• Quality-adjusted life years (QALYs) are commonly used in health economics to measure health outcomes.
• Societal health indices are crucial for guiding healthcare policy decisions.
• Existing QALY-based indices may not fully capture the complexities of population health.

Purpose of the Study:

• To assess the appropriateness of QALYs for a societal health index.
• To evaluate the feasibility of using such an index for healthcare policy.
• To identify potential ethical concerns and data limitations in QALY-based health indices.

Main Methods:

• Analysis of the ethical implications of aggregate QALY indices.
• Examination of data sufficiency for corrected QALY index estimation.
• Construction of a QALY-based index using available Canadian health data.

Main Results:

• Standard aggregate QALY indices may promote health inequality.
• Life expectancy alone overstates Canadian community health by approximately 10% due to morbidity.
• Morbidity's impact on health status is unequal across Canadian regions and genders.
• Role and mobility dysfunctions are key determinants of ill-health.

Conclusions:

• QALYs, while useful, require careful ethical consideration for societal health indices.
• Current data limitations hinder the precise estimation of corrected QALY-based indices.
• A comprehensive QALY-based index reveals significant, unequally distributed impacts of morbidity on Canadian health status.
