Twitter, algorithme et abus de médicaments

L’augmentation des intoxications et d’abus de médicaments de prescription médicale est un vrai problème aux Etats Unis. La nature croissante de ce problème nécessite de mettre en place des stratégies de surveillance pour calculer la prévalence et les caractères de l’abus de médicaments spécifiques. C’est ainsi que les auteurs d’une étude publiée dans Drug Safety ont évalué la possibilité d’utiliser un réseau social comme Twitter, outil de surveillance et concevoir une technique de classification automatique (algorithme) permettant d’identifier des « posts » d’usage abusif de médicaments.

WASHINGTON JAN. 14, 2016 Federal investigators said Thursday that there were flaws in the way the Food and Drug Administration tracked drugs after they came to market, raising questions about the agency’s effectiveness as the country’s main drug overseer.

The FDA just released a guidance formalizing its practice of notifying the public of « emerging signals, » or situations in which the agency is monitoring risks that have not yet been fully validated, and for which the agency does not have specific recommendations. The latest guidance appears to be inspired by that episode, and includes a list of considerations for determining when to notify the public of an « emerging signal, » as well as the template for communicating the issue. The issuance of a formal policy suggests the FDA anticipates increased communication of emerging signals as it beefs up its surveillance capabilities …

Patty Murray, a Washington Democrat, blames device manufacturers, hospitals, and the Food and Drug Administration for infections that sickened at least 250 people worldwide since 2012 and that may have contributed to dozens of deaths. The series of outbreaks went on for years before safety problems with the endoscopes came to light in the media in 2015. The report says the events expose systemic weaknesses in the FDA’s approach …

In an attempt to gain more health information, United Kingdom-based pharmaceutical company GlaxoSmithKline has begun collecting data from social media sites such as Facebook and Twitter that mention any of a company’s 1,000 different drugs. In its partnership with United States-based informatics company Epidemico, the two found over six million Twitter mentions and more than 15 million Facebook hits.
