Defining monetary values for quality of life improvements: an exploratory study

Area of Science:

• Health Economics
• Quality of Life Research
• Health Intervention Valuation

Background:

• Quality of Life (QOL) improvements often reflect overall health intervention effectiveness.
• Quantifying the monetary value of QOL improvements is crucial for assessing intervention value.
• Establishing a link between QOL and willingness to pay (WTP) can aid economic evaluations.

Purpose of the Study:

• To assess the feasibility of monetizing health interventions.
• To translate Quality of Life (QOL) improvements into monetary values (willingness to pay).
• To explore the relationship between QOL gains and WTP for health interventions.

Main Methods:

• Development of seven hypothetical health state scenarios.
• Distribution of self-administered questionnaires to 545 randomly selected university staff.
• Collection of data on perceived QOL for various health states and WTP for improvement to perfect health.

Main Results:

• A 55% response rate (n=294) was achieved.
• Significant correlations were observed between WTP, anticipated QOL improvement, and respondent income.
• A regression model, while explaining 20% of WTP variance, accurately predicted mean WTP amounts.

Conclusions:

• A clear correlation exists between willingness to pay for health interventions and the degree of Quality of Life improvement.
• Monetizing QOL improvements is a feasible approach for valuing health interventions.
• Further research can refine the predictive power of WTP models for health interventions.
