What does a utility function in health economics represent?

In health economics, a utility function is a fundamental concept that captures an individual's preferences and the level of satisfaction they derive from different health states or choices. It quantitatively represents how individuals value various outcomes, allowing economists to analyze decisions related to health care. Utility functions help in understanding how different factors, such as health status or access to services, impact a person's overall well-being.

By estimating utility values, health economists can make comparisons across different health interventions, assess health outcomes, and guide decision-making in resource allocation. A utility function essentially models how individuals weigh the trade-offs between health outcomes and the consumption of health-related goods and services, thereby reflecting their subjective valuation of health and life quality.

In contrast, budget constraints refer to the financial limitations that individuals have in terms of spending on health care, while measures of hospital efficiency assess how well hospitals utilize resources to deliver care. The overall cost of health care services concerns the expenses incurred for medical treatments and procedures, which does not directly relate to individual preferences or satisfaction. Thus, the utility function stands distinct as a representation of individual choices and satisfaction in the context of health economics.
