BioSim has organized, in collaboration with the Spanish Patient Forum (FEP), the Information Day "Biosimilars: quality, safety and efficiency". An initiative whose purpose is to train and inform patients about biosimilars and resolve any doubts that may arise. This Conference is divided into two training videos. The second presentation "biosimilars in the clinical practice" by Dr. Adriana Pascual, currently deputy medical director of the Infanta Elena Hospital, describes the implementation of biosimilars in her hospital, her experience with biosimilar medicines in her usual clinical practice and the doctor-patient relationship around this segment of drugs.
