Cost minimization analysis (CMA) compares two interventions or strategies that are assumed to have the same outcomes in order to determine the least costly option. CMA focuses only on costs and assumes equivalence between options' benefits. It is commonly used to compare drugs of equal efficacy and tolerability in pharmacoeconomics. CMA involves calculating and comparing the total costs associated with each option, including acquisition, administration, supplies, personnel, and other direct and indirect costs. It is useful for identifying the most cost-effective alternative when outcomes are equivalent.
