New system for detecting adverse effects of medications using social media

Researchers at Carlos III Universidad de Madrid have developed a system for detecting adverse effects of pharmaceutical drugs by tracking information generated by patients on specialized blogs or social networks such as Twitter in real time. The prototype, created by these scientists within the framework of the European research Project TrendMiner, makes it possible to analyze the comments on social media by using natural language processing techniques (NLP). Thanks to these techniques, patients’ colloquial descriptions are « translated » into manageable data in comparatives studies which allow us to identify patterns and trends. » This data may also be combined with data from …

SocialVigilance | Searching social networks to detect adverse reactions

Social Vigilance, Pharmacovigilance

Regulators and pharmaceutical companies are monitoring social media posts for potential adverse drug reaction signals.

Pharmacovigilance et Réseaux Sociaux : Faculté Pharma Paris-Descartes le 06/12/2013

Le système de pharmacovigilance classique (via la notification spontanée) semble s’essouffler.  De nouvelles sources d’informations telles que les forums de discussion patient, blogs, réseaux sociaux (Facebook, twitter) ont été récemment identifiées comme possible sources complémentaires dans le processus de surveillance des effets indésirables susceptibles d’être liés à l’usage d’un médicament. Les moteurs de recherche et les forums Internet spécialisés apparaissent à ce titre comme une mine infinie de renseignements à explorer. Être à l’écoute des réseaux sociaux pourrait permettre de détecter des signaux faibles. L’ANSM a par ailleurs retenu cette année  lors de son  2ème appel à projets « Recherche », un …
