An Introduction of EVIDEM Framework and Its Application in Healthcare Decision Making / 中国实验方剂学杂志

ABSTRACT

Evidence and value：impact on DEcisionMaking （EVIDEM） framework was developed by EVIDEM collaboration. Its core is the combination of multiple criteria decision analysis （MCDA） model and standardized health technology assessment （HTA） report， which aims to evaluate the overall value of medical interventions. It has been tested and implemented in the real-world evaluation environments. After more than 10 years of development， EVIDEM framework has been updated to version 10， and the relevant operation manuals have been published. More than 40 countries have joined the collaboration and more than 20 countries have carried out relevant studies. The framework is constructed with patients， population and sustainability as the overall goals， combing the evidence and value， forming a relatively complete decision-making framework system composed of 2 levels， 7 dimensions and 20 criteria. The two levels include normative universal criteria and contextual criteria. The normative universal criteria， namely EVIDEM core model， is the quantitative evaluation， consisting of 5 dimensions and 13 criteria. Contextual criteria， namely contextual tools， are qualitative evaluation， consisting of 2 dimensions and 7 criteria. The specific operation steps of EVIDEM framework include selecting and constructing criteria， assigning weights， integrating and evaluating evidence， quantitative and qualitative evaluation of value， comprehensive value estimation and ranking based on value estimation. EVIDEM framework is applicable to disease diagnosis， treatment， management and other fields. Its application scope includes medical insurance reimbursement， clinical practice decision-making， drug selection and so on， which can provide a method for more systematic， transparent and scientific healthcare decision-making. At present， the framework has been introduced into the field of traditional Chinese medicine and can provide a scientific and feasible evaluation tool and methodology system for the clinical comprehensive evaluation of Chinese patent medicine.
