How to estimate productivity costs in economic evaluations

Area of Science:

• Health Economics
• Pharmacoeconomics
• Outcomes Research

Background:

• Productivity costs are often excluded from economic evaluations, impacting cost-effectiveness findings.
• Lack of standardized methodology for estimating productivity costs hinders consistent application.

Purpose of the Study:

• To standardize productivity cost methodology in economic evaluations.
• To provide practical guidance on estimating productivity costs.
• To improve the accuracy of cost-effectiveness analyses.

Main Methods:

• Discusses identification, measurement, and valuation of productivity losses.
• Recommends inclusion of both paid and unpaid work productivity losses.
• Suggests using validated instruments like the iMTA Productivity Cost Questionnaire (iPCQ) or Valuation of Lost Productivity (VOLP).

Main Results:

• Highlights the importance of including productivity costs for robust economic evaluations.
• Offers guidance on applying the friction cost and human capital approaches.
• Provides practical steps for deriving final productivity cost estimates.

Conclusions:

• Standardized methodology for productivity costs is essential for reliable economic evaluations.
• Comprehensive measurement including unpaid work enhances cost-effectiveness assessment.
• Practical guidance facilitates consistent and accurate estimation of productivity costs.
