Erik Nord: Cost-value analysis in health care. Making sense out of QALYs. Cambridge University Press 1999. 145 pages. Available at amazon.com.
The book is hopefully of interest to researchers, health administrators and health professionals. It may also be suitable as a student text book in health economics, political science and medical ethics. Please find below: Summary, specific messages, table of contents.
Summary: A number of empirical studies show strong concerns for fairness and equity in health care in most countries. Current economic evaluation models like the conventional QALY-model (cost-utility analysis) fail to capture these concerns. Ways to incorporate these concerns are outlined. The relevance of formal models for decision making is discussed.
’Among the strengths of the book are its excellent exposition and its success in raising insightful and crucially important issues, making a major contribution to ongoing debates.’ - Amartya Sen
- Cost-utility analysis places too much weight on the probability of treatment success.
- Cost-utility analysis places too much weight on the number of years that patients get to enjoy health improvements.
- Quality of life data obtained from patients should replace hypothetical valuations of health states.
- Standard gamble does not capture all aversion to risk.
- Life years gained in disabled people should be valued as much as life years gained in health people.
- Formal economic evaluation should be restricted to budget decisions (as opposed to clinical decisions).
- Cost-per-QALY league tables falsely assume that ’winners should take all’.
