CEA is a method used to compare the costs and benefits of different healthcare interventions. It aims to identify the intervention that provides the greatest health benefit at the lowest cost.

ICER is not a component of a CEA. It is a measure of the additional cost per unit of health benefit gained from one intervention compared to another.

HTA is a process that evaluates the clinical effectiveness, cost-effectiveness, and impact of new healthcare technologies on patient outcomes.

Clinical trials are not a type of HTA. They are a type of research study that evaluates the safety and effectiveness of new healthcare interventions.

Economic evaluation plays a crucial role in healthcare decision-making by providing information about the costs, benefits, and impact of different healthcare interventions. This information can be used to make informed decisions about the allocation of healthcare resources.

ROI analysis is not a type of economic evaluation. It is a financial analysis tool used to assess the profitability of an investment.

The primary difference between cost-effectiveness analysis and cost-utility analysis is the measure of health benefit used. Cost-effectiveness analysis uses a measure of health benefit that is specific to the intervention being evaluated, while cost-utility analysis uses QALYs, which are a generic measure of health benefit.

The ICER is a measure of the additional cost per unit of health benefit gained from one intervention compared to another. It is calculated by dividing the difference in costs between the two interventions by the difference in health benefits.

QALYs are a generic measure of health benefit that can be used to measure the health benefits of healthcare interventions, compare the health benefits of different healthcare interventions, and determine the cost-effectiveness of healthcare interventions.

Ethical considerations are not a challenge in conducting health economic evaluations. They are a consideration in the design and conduct of any research study, but they are not specific to health economic evaluations.

Sensitivity analysis is a technique used to assess the impact of uncertainty on the results of a health economic evaluation. It involves varying the values of key input parameters and observing the impact on the results.

Deterministic sensitivity analysis is not a type of sensitivity analysis. It is a method for assessing the impact of uncertainty on the results of a health economic evaluation by varying the values of key input parameters one at a time.

Probabilistic sensitivity analysis is a technique used to assess the impact of uncertainty on the results of a health economic evaluation by varying the values of key input parameters simultaneously and randomly.

One-way sensitivity analysis is not a type of probabilistic sensitivity analysis. It is a method for assessing the impact of uncertainty on the results of a health economic evaluation by varying the values of key input parameters one at a time.
