Résumé

Multiple sclerosis (MS) is a frequent neurological condition affecting young adults with acute disabling neurological episodes (relapses). MS relapses are not recorded in claims databases despite their importance for (pharmaco)epidemiological studies. This study aimed to validate and improve an algorithm identifying relapses in relapsing-remitting MS initiating disease-modifying therapy (DMT) within the French nationwide claims database (SNDS).
