The value of extending healthy life expectancy: A framework for healthcare policy evaluation

The widening gap between life expectancy (LE) and healthy life expectancy (HALE) has led to an increase in healthcare burden. Extending HALE presents a promising solution. However, realizing HALE extension requires substantial policy support, necessitating a quantitative and rational assessment of its value. Based on the economic model of the value of a statistical life (VSL), we propose a quantitative framework to measure the value of extending HALE and to assess related policy impacts. This modeling framework incorporates regional characteristics and quality of life (QoL), providing a flexible tool for evaluating healthcare policies. Through numerical analysis, we demonstrate that the value of HALE extension varies across age and QoL scenarios, suggesting the necessity of incorporating these factors to ensure effective policy implementation. Our analysis of policy impact highlights the realistic effect of HALE extension initiatives and potential benefits of narrowing the gap between LE and HALE. From a policy-making perspective, narrowing this gap could significantly alleviate healthcare burdens.
