Comparison of weighting methods used in multicriteria decision analysis frameworks in healthcare with focus on low- and middle-income countries

AIM: Criteria weighting is a key element of multicriteria decision analysis that is becoming extensively used in healthcare decision-making. In our narrative review we describe the advantages and disadvantages of various weighting methods. METHODS: An assessment of the eight identified primary criteria weighting methods was compiled on domains including their resource requirements, and potential for bias. RESULTS: In general, we found more complex methods to have less potential for bias; however, resource intensity and general participant burden is greater for these methods. CONCLUSION: The selection of the most appropriate method depends on the decision-making context. The simple multiattribute rating technique (SMART) method combined with swing-weighting technique and the analytic hierarchy process methods may be the most feasible approaches for low- and middle-income countries.
