Cost-benefit analysis (CBA)
CBA compares the costs and bene ts of two interventions quanti ed in common monetary units. It requires that bene ts such as life-years gained, disability days avoided, or medical complications avoided, be represented in a monetary value that could be interpreted with the costs. It may also be useful when we want to determine whether health investment reduces costs. For example, a 2018 study examined whether a Colombian insurer’s investment in preventive programs can reduce work‐related injuries and costs associated (5). Therefore, they conducted a cost-bene t analysis of investments in preventive measures from the insurer’s perspective. Data was based on a group of companies a liated with a private insurer in Bogota, Colombia. Parameters evaluated included the number of employees, level of labour risk, type of sector, and information related to the 5 Shares insurer’s investments in prevention at the company for each month. Researchers also included data related to injuries at work, medical costs, sick-leave costs, legal costs, and insurance compensation. All variables were represented as monetary units for analysis. Results showed a positive relationship between investments and occupational injury reduction. They found a cost-bene t ratio of 1.3 from the insurer’s perspective. As we can see, in this type of cost-bene t analysis ratio, the formula is represented as: The results are usually written as “Cost-bene t ratio of 2”. On the other hand, if you want to calculate a cost-bene t ratio, the following formula must be used: In turn, results of net bene t in cost-bene t are usually written as “Net cost of $35 000”. Cost minimization analysis (CMA) Lastly, there is a type of health evaluation rarely used: Cost-minimization analysis (CMA). This evaluation has an assumption that the results of two or more health interventions are equivalent, so the di erence between them becomes a cost comparison. Commonly, it is used when there is an evidence-based decision history 5 Shares where we know that the outcomes are similar, but the basis remains questionable (6). The analysis tends to be justi able when we evaluate therapies with similar technologies. Therefore, the results of the cost-minimization analysis are usually presented as “Intervention A is less expensive than intervention B”.
