What outcome unit does cost-utility analysis use?

  1. Dollars

  2. Natural units

  3. Quality adjusted life year (QALY)

  4. Equivalent outcomes

The correct answer is: Quality adjusted life year (QALY)

Cost-utility analysis utilizes Quality Adjusted Life Years (QALY) as the outcome unit. QALY combines both the quantity and the quality of life lived after a healthcare intervention. It is a standardized measure that considers both the additional years of life that might be gained due to a treatment as well as the quality of life during those years. This makes it a valuable tool for comparing the effectiveness of different healthcare interventions across various health conditions. It is a widely accepted measure in health economics for assessing the value of healthcare interventions.
