The 2020 National Report "Medicines use in Italy", produced by the National Observatory on the Use of Medicines (OsMed) of the Italian Medicines Agency (AIFA), describes the Italian pharmaceutical assistance through different available information flows that allow to recompose pharmaceutical territorial and hospital assistance, concerning both the national health service and private citizens. In the Report the results of numerous analyzes, both general and focused on specific therapeutic categories and classes, relating to pharmaceutical expenditure and consumption, are reported, but it is also present an in-depth analysis about monitoring registries and conditional reimbursement agreements, and a comparison between the most relevant Italian data and those of nine other European countries.
