2) Semi-standardized Pharmacovigilance Interviews (SPI) which are unscheduled, and are performed in the case of an AE reported by the patient to the CRA, or in the case of a direct phone call to the pharmacovigilance center by the patient or their baclofen prescriber, with the aim to report an AE. Data collected are: current baclofen dose and recent changes in baclofen dosing, recent and current drinking patterns, associated medications, type of AE, 'serious' feature of the AE according to the definition of the Food and Drugs Administration, onset date and occurrence conditions. Patients can be secondarily re-contacted to assess the final outcome of the AE, and to determine the causality score of baclofen regarding the AE, using both the French causality method and the Naranjo's algorithm if applicable.
