Economic evaluations assuming constant returns to scale are challenged by increasing returns due to fixed capital costs. Cost-effectiveness analysis must consider multiple patient groups simultaneously for optimal investment decisions.

Area of Science:

  • Health Economics
  • Decision Science

Background:

  • Traditional cost-effectiveness analysis (CEA) often assumes constant returns to scale.
  • This assumption is increasingly criticized, questioning CEA's utility in decision-making.

Purpose of the Study:

  • To analyze CEA under increasing returns to scale, specifically due to fixed capital costs.
  • To compare different decision rules within CEA when fixed costs are present.

Main Methods:

  • Economic modeling of cost functions incorporating fixed capital costs.
  • Evaluation of two decision rules: the budget approach and the constant price approach.
  • Analysis of CEA for multiple patient groups sharing an investment.

Main Results:

  • The budget approach can lead to suboptimal outcomes in the presence of fixed capital costs.

  • The constant price approach yields optimal solutions under these conditions.
  • Fixed capital costs create interdependencies between patient groups, necessitating simultaneous analysis.

    • Conclusions:

    • CEA requires careful consideration of returns to scale, particularly fixed capital costs.
    • The constant price approach is superior to the budget approach for optimizing resource allocation.
    • Joint cost-effectiveness analysis across all potential user groups is crucial for investments with fixed capital costs.
