Health Economic Evaluation Basics - Putting a price tag on health -

Summary

This video introduces the concept of health economic evaluation, a tool used to compare health interventions based on their costs and outcomes. It explains the four main types of economic evaluations: cost minimization, cost effectiveness, cost utility, and cost benefit analysis. The video highlights the importance of considering direct, indirect, and intangible costs when assessing interventions. It also explores the concept of quality-adjusted life years (QALYs) for comparing different health outcomes. The video concludes by discussing the complexities involved in conducting economic evaluations, including statistical adjustments and uncertainty management.

Takeaways

• 😀 Health economic evaluations help in making decisions about how limited resources are allocated to health interventions.
• 😀 Opportunity cost is the concept of having to make difficult decisions due to limited resources, which health economic evaluation helps address.
• 😀 There are four main types of economic evaluations: cost minimization, cost effectiveness, cost utility, and cost benefit analysis.
• 😀 Direct costs are those directly linked to an intervention, like medicines, equipment, and healthcare staff salaries.
• 😀 Indirect costs include losses due to illness-related productivity reduction, such as missed wages.
• 😀 Intangible costs are subjective and harder to measure, such as pain, suffering, or grief.
• 😀 Cost minimization analysis is used when comparing interventions with the same outcomes but different costs.
• 😀 Cost effectiveness analysis compares interventions with the same health outcome, such as the reduction in blood pressure or weight loss.
• 😀 Cost utility analysis compares interventions with different health outcomes using a common measure, like the quality adjusted life year (QALY).
• 😀 QALY combines both the number of years lived and the quality of those years to assess the value of an intervention.
• 😀 Cost benefit analysis involves measuring both costs and outcomes in monetary terms, including direct, indirect, and intangible costs.

Q & A

What is the main purpose of health economic evaluations?

Health economic evaluations help to compare different health interventions on the basis of their costs and outcomes, guiding decisions on how to allocate limited health resources effectively.

Why are health economic evaluations necessary despite the availability of effective health interventions?

Health economic evaluations are necessary because there is typically a limited amount of funding for health interventions. Without these evaluations, it would be difficult to prioritize the most beneficial programs given the opportunity cost of not being able to fund all interventions.

What is opportunity cost in the context of health economics?

Opportunity cost refers to the cost of forgoing other potential interventions when funds are allocated to a particular health program, meaning that spending on one intervention reduces the ability to fund others.

What are direct costs in health economic evaluations?

Direct costs are expenses directly associated with a health intervention, such as the cost of medicines, equipment, salaries of healthcare staff, and transport to health centers.

How do indirect costs differ from direct costs in health economic evaluations?

Indirect costs are associated with reduced productivity due to illness or its treatment, such as missed wages from being unable to work, whereas direct costs are directly tied to the intervention itself.

What are intangible costs, and why are they difficult to measure?

Intangible costs refer to subjective factors like pain, suffering, or grief due to illness or treatment. These costs are challenging to quantify in monetary terms, making them difficult to measure in economic evaluations.

What is a cost minimization analysis, and when is it used?

Cost minimization analysis is used when comparing two interventions that produce the same outcome, focusing solely on comparing the costs of the different options.

Can you give an example of a cost-effectiveness analysis?

In a cost-effectiveness analysis, if two weight loss programs are compared—one diet-based and the other medication-based—the cost per kilogram of weight lost is calculated for each. The intervention with the lower cost per kilogram is considered more cost-effective.

What is a quality-adjusted life year (QALY), and why is it important in health economics?

A quality-adjusted life year (QALY) combines both the quantity and quality of life into a single measure, allowing for the comparison of interventions with different health outcomes. It is essential for comparing interventions that affect various aspects of health, such as longevity and quality of life.

What is the difference between cost utility analysis and cost benefit analysis?

Cost utility analysis compares the cost of an intervention relative to health outcomes measured in QALYs or other utility measures, while cost benefit analysis measures both costs and outcomes in monetary terms, accounting for all types of costs, including indirect and intangible ones.
