In recent years Fracture Liaison Services (FLS) have been established worldwide to reduce the number of fractures due to osteoporosis. Within the framework of the global campaign «Capture the fracture» by International Osteoporosis Foundation (IOF), some questionnaires have been proposed to assess the quality of FLS’ organization. Key Performance Indicators (KPIs) are used to analyze the effectiveness of the FLS working at the patient level. Thanks to their use, it is possible to identify areas that need improvement, evaluate the effectiveness of the changes being made, and compare the quality of work in various FLS at the regional or country level. This article discusses approaches to the use and calculation of each KPI in practical healthcare in the Russian Federation, taking into account epidemiological data, national clinical guidelines, and the specifics of the organization of the healthcare system in our country.
