Cost Utility Analysis
Cost Utility Analysis (CUA) is a method of economic evaluation that compares the cost and outcomes of different courses of action. CUA measures benefits in terms of Quality Adjusted Life Years (QALYs) or Disability Adjusted Life Years (DALYs). This type of analysis enables comparison across different sectors and interventions. CUA is often used in the health care sector, helping with decisions related to health-related quality of life improvements.
Guide to Cost Utility Analysis
Cost Utility Analysis (CUA) is a form of economic analysis used to guide investment decisions. It compares the relative costs and outcomes (effects) of two or more courses of action, commonly measured in 'utility' units called 'Quality Adjusted Life Years' (QALYs).
In detail, Cost Utility Analysis helps to compare the cost per unit of outcome for each choice of course, making it a powerful tool for determining the most effective use of limited resources.
Why it is important?
CUA provides a methodical approach to making resource-allocation decisions. By quantifying and comparing the expected benefits and costs using a common measure, CUA can reveal the most effective option.
How it works:
CUA involves four key steps:
1. Identification of alternative options2. Measurement of costs (in monetary terms) and benefits (in QALYs) associated with each option3. Conversion of costs and benefits into cost-per-utility ratios4. Comparison of the ratios to identify the option with the best return on investment.
Exam Tips: Answering Questions on Cost Utility Analysis:
1. Understand the fundamental concepts: Make sure you have a firm grasp on the basics of CUA, including QALYs, costs and benefits analysis, conversion to cost-per-utility ratios, and comparison of these ratios.
2. Be able to apply CUA concepts: You should be able to work through a CUA calculation in an exam question. Given information about the costs and benefits of different options, you should be able to calculate the cost-per-utility ratios and identify the most favourable option.
3. Practice: Practising CUA calculations will help you become familiar with the process, and increase your speed and accuracy.
4. Show your work: In an exam, make sure you clearly state your process and assumptions. This shows the examiner that you understand the process, and may earn you partial marks even if your final answer is incorrect.
