Drug Safety Matters is the pharmacovigilance podcast of Uppsala Monitoring Centre. Its subject is the machinery of medicine safety: how harms get reported, counted, analysed and acted on. Episodes centre on named guests. The titles give the range: 'How to perform better disproportionality analyses' with Michele Fusaroli and Eugene van Puijenbroek, two parts of 'Rethinking medical device safety' with Omar Aimer, an episode with Shanthi Pal on the WHO Global Smart Pharmacovigilance Strategy, and two parts of 'How to use artificial intelligence in pharmacovigilance' with Niklas Norén. That run leans toward method and practice. The disproportionality conversation opens on a method it calls easy and fast, then adds a caveat. Its clearest example is edaravone, a drug prescribed for amyotrophic lateral sclerosis, which shows a huge disproportionality with the disease it treats. The explanation offered is reverse causality: the event is the reason for taking the drug, and spotting that takes clinical understanding. Confounding comes next as a second trap. The medical device episodes widen the frame beyond pills, to everything from bandages to MRI machines. Devices can malfunction, degrade and interact with users in ways drugs cannot, and a software update can shift a device's risk profile. Cybersecurity and usability become safety questions, and health apps that measure signs on phones and smartwatches count as devices too. The fixes proposed are practical. Reporting should be simpler and built into everyday tools such as prescription software. It should also come with follow-up loops that show healthcare professionals what their reports led to. In Shanthi Pal's episode the theme is reliance: countries pooling data to strengthen a study, or one country building on another's results instead of repeating the work. Repeated active surveillance of malaria and HIV medicines is raised as spending that limited resources cannot support. The artificial intelligence conversation, with Niklas Norén, head of research at the centre, is split into two parts. It covers the uneven cost of mistakes. Missing a pair of duplicate reports wastes time, while wrongly removing an important report could delay a signal. Explainability gets the same task-by-task treatment. It is seen as essential for ambiguous work like signal detection and less needed for de-identification, where measured performance may be enough. Several voices present the show, including Federica Santoro and Alexandra Coutinho. Sign-offs credit listeners by first name for the questions they sent in, and a Fan Mail feature lets anyone text the show anonymously through a link in the show notes. The disproportionality episode is a good first listen, because the edaravone case shows in one example why a statistical signal is not yet a verdict.
