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.

Multiple Criteria Decision Analysis (MCDA) is increasingly used in health care mainly because it moves decision-making from ad hoc to an evidence-based and comprehensive process. Developing countries with more restricted financial and human research capacities, however, should consider their own methods of MCDA development and implementation. Areas covered: An MCDA framework to improve procurement decisions of off-patent pharmaceuticals was developed for developing countries and adapted to Indonesia, Kazakhstan and Vietnam during three policy workshops. Based on the experience of these workshops and one joint workshop with international experts and decision makers from multiple developing countries, general recommendations were formulated on how to implement MCDA specifically in developing countries. We provide 17 practical MCDA implementation recommendations in four major areas, including (1) MCDA objectives; (2) technical considerations of MCDA tool; (3) development and customization of MCDA tool and (4) policy implementation of MCDA in decision-making. Expert commentary: These practical MCDA recommendations for developing countries contribute to feasible, transparent, stepwise, iterative and standardized decision-making in health care.

BackgroundOff-patent pharmaceuticals (OPPs) hold vital importance in meeting public health objectives, especially in developing countries where resources are limited. OPPs are comprised of off-patent originals, branded generics and unbranded generics; nonetheless, these products are not identical and often there are differences in their equivalence, manufacturing quality standards and reliability of supply. This necessitates reconsideration of the lowest price policy objective in pharmaceutical decision making. The aim of this study was to develop a Multi-Criteria Decision Analysis (MCDA) framework through a pilot workshop to inform the national procurement of OPPs in Indonesia.MethodsAn initial list of potentially relevant criteria was identified based on previous work and a literature review. In a 2-day pilot policy workshop, twenty local experts representing different stakeholder groups and decision-making bodies selected the final criteria, approved the scoring function for each criterion, and assigned weights to each criterion.ResultsAn MCDA framework was proposed for OPP drug decision making in developing countries, which included price and 8 non-price criteria. Based on the pilot policy workshop 6 + 1 criteria were considered relevant for Indonesia: pharmaceutical price (40% weight), manufacturing quality (18.8%), equivalence with the reference product (12.2%), product stability and drug formulation (12.2%), reliability of drug supply (8.4%), real world clinical or economic outcomes, such as adherence or non-drug costs (4.2%) and pharmacovigilance (3.6%).ConclusionsAccording to the pilot policy workshop, other criteria apart from price need to be strengthened in the tendering process. The introduction of additional criteria for OPP procurement in an MCDA framework creates incentives for manufacturers to invest into improved manufacturing standards, equivalence proof, product quality, reliability of supply or even additional real-world data collection, which ultimately may result in more health gain for the society.

Off-patent pharmaceuticals (OPPs) represent more than 60% of the pharmaceutical market in many emerging countries, where they are frequently evaluated primarily on cost rather than with health technology assessment. OPPs are assumed to be identical to the originators. Branded and unbranded generic versions can, however, vary from the originator in active pharmaceutical ingredients, dosage, consistency formulation, excipients, manufacturing processes, and distribution, for example. These variables can alter the efficacy and safety of the product, negatively impacting both the anticipated cost savings and the population's health. In addition, many health care systems lack the resources or expertise to evaluate such products, and current assessment methods can be complex and difficult to adapt to a health system's needs. Multicriteria decision analysis (MCDA) simple scoring is an evidence-based health technology assessment methodology for evaluating OPPs, especially in emerging countries in which resources are limited but decision makers still must balance affordability with factors such as drug safety, level interchangeability, manufacturing site and active pharmaceutical ingredient quality, supply track record, and real-life outcomes. MCDA simple scoring can be applied to pharmaceutical pricing, reimbursement, formulary listing, and drug procurement. In November 2015, a workshop was held at the International Society for Pharmacoeconomics and Outcomes Research Annual Meeting in Milan to refine and prioritize criteria that can be used in MCDA simple scoring for OPPs, resulting in an example MCDA process and 22 prioritized criteria that health care systems in emerging countries can easily adapt to their own decision-making processes.
