To mark #MedSafetyWeek, which takes place from 6–12 November, we’re releasing a special two-part episode on pharmacovigilance communication campaigns. In this first part, we speak to Mitul Jadeja from the Medicines and Healthcare products Regulatory Agency in the UK about under-reporting and how initiatives like #MedSafetyWeek can help. Tune in to find out: Why under-reporting plagues all pharmacovigilance systemsWhat regulators can do to encourage people to report side effectsWhy we need reports from both patients and healthcare professionalsWant to know more?  Here are the studies cited in the episode: A BMJ study in 2022 measured the burden and associated cost of adverse drug reactions, polypharmacy and multimorbidity at a hospital in the UK.In 1976, Inman proposed a theoretical model, known as the ‘seven deadly sins’, to explain why healthcare professionals fail to report adverse drug reactions. This recent systematic review in Drug Safety expands on that. The SCOPE Joint Action project aimed to enhance pharmacovigilance in the EU and delivered practical guidance for regulators.The first UK study to compare Yellow Card reports from patients and healthcare professionals was published in 2012.To join the #MedSafetyWeek campaign next week, follow the hashtag online and check out the campaign website for free social media materials.
