[Indirect cost assessment in health evaluation]

Area of Science:

• Health Economics
• Public Health
• Disease Impact Assessment

Background:

• The inclusion of indirect costs in health economic analyses remains a debated topic.
• Indirect costs, such as lost productivity, significantly contribute to the overall burden of illness.
• Current analyses often underestimate the true societal impact of diseases by excluding these costs.

Purpose of the Study:

• To advocate for the inclusion of indirect costs in health economic evaluations.
• To outline methodologies for calculating indirect disease costs.
• To illustrate the economic impact of diseases, considering both direct and indirect costs.

Main Methods:

• Literature review on the methodologies for calculating indirect costs.
• Case study analysis of HIV/AIDS, focusing on its social and economic relevance.
• Case study analysis of migraine, highlighting its indirect cost burden despite low direct costs.

Main Results:

• Indirect costs represent a substantial, often underestimated, component of the total economic burden of diseases.
• Excluding indirect costs can lead to a misallocation of resources and underestimation of intervention benefits.
• Both high-profile (HIV/AIDS) and seemingly low-burden (migraine) diseases have significant indirect cost implications.

Conclusions:

• Incorporating indirect costs provides a more comprehensive understanding of a disease's societal and economic impact.
• Accurate calculation of indirect costs is essential for informed health policy and resource allocation decisions.
• Reconsidering diseases like migraine through the lens of indirect costs reveals a greater overall burden than previously recognized.
