The evidence obtained in clinical trials (CTs) and real world evidence (RWE) studies represents a joint evidence base for health technology assessment and decision-making in healthcare. The key factors for RWE acceptance by the regulatory authorities and health technology assessment agencies are quality of original data and proper methods for processing of these data. The lack of a unified regulatory framework for planning and conducting the RWE studies significantly complicates this objective. This manuscript is devoted to systematic approach to development and implementation of RWE direction in a company. This approach is aimed at ensuring the quality of results. The authors describe all the key components necessary for development and implementation of RWE direction in a company: strategy, analysis of internal and external environment, quality management system (QMS), partnership model and processes for development and implementation of RWE studies. The main actions and objectives for each stage of RWE are formulated. Relationship of each stage with ensuring the quality of RWE study results is shown. The key internal processes and minimum necessary requirements for each of processes has been described for the first time in the Russian-language scientific literature. The described systematic principles can be leveraged to implement an innovation not only in pharmaceutical companies or contract research organizations, but also in partner companies providing access to data and/or information technologies, healthcare organizations and research institutes. Implementation of principles, requirements, methods and algorithms significantly contribute to establishment of RWE direction in companies and form a systematic approach to ensuring the quality of RWE studies results.
