Abstract
Background: Safety advisories provide critical information to clinicians and patients on the harms of medicines. Previous research has shown that national regulators vary in their decisions to issue safety warnings. However, it is not known whether clinicians receive similar information when regulators communicate about the same medicines' harms.
Aim: Our aim was to assess whether content provided to clinicians in safety advisories on risk, fatal outcomes, evidence and clinician advice was comparable.
Methods: This retrospective content analysis examines safety advisories issued by the Australian Therapeutic Goods Administration, Health Canada, the United Kingdom Medicines and Healthcare products Regulatory Agency, and the US Food and Drug Administration between 2007 and 2016. Content was extracted from advisories issued on the same medicine and harm (n = 40), including evidence, risk quantification, fatal outcomes and clinician advice. A case study on pioglitazone and bladder cancer illustrates differences in regulatory communications.
Results: Variation was seen in the detail and presentation of information on evidence, deaths, risk quantification and advice to clinicians. Specific advice to clinicians was provided in 70% (96/155) of advisories with no significant differences between regulators (p = 0.19). Evidence of harm was presented in 81% (130/160) of advisories and risk quantification in 61% (98/160). The type of evidence presented and directness of information differed however. In the pioglitazone case study, for example, regulators differed in how bladder cancer risks were characterised and advice provided.
Conclusions: Our analysis of safety advisories on the same harms of medicines indicates that while regulators provide similar content elements in safety advisories, risk messages to clinicians vary. This may lead to differences in knowledge and awareness between countries and potentially impact public health outcomes. Further transparency around regulatory decisions on safety advisories is needed.
期刊介绍:
Pharmaceutical Medicine is a specialist discipline concerned with medical aspects of the discovery, development, evaluation, registration, regulation, monitoring, marketing, distribution and pricing of medicines, drug-device and drug-diagnostic combinations. The Journal disseminates information to support the community of professionals working in these highly inter-related functions. Key areas include translational medicine, clinical trial design, pharmacovigilance, clinical toxicology, drug regulation, clinical pharmacology, biostatistics and pharmacoeconomics. The Journal includes:Overviews of contentious or emerging issues.Comprehensive narrative reviews that provide an authoritative source of information on topical issues.Systematic reviews that collate empirical evidence to answer a specific research question, using explicit, systematic methods as outlined by PRISMA statement.Original research articles reporting the results of well-designed studies with a strong link to wider areas of clinical research.Additional digital features (including animated abstracts, video abstracts, slide decks, audio slides, instructional videos, infographics, podcasts and animations) can be published with articles; these are designed to increase the visibility, readership and educational value of the journal’s content. In addition, articles published in Pharmaceutical Medicine may be accompanied by plain language summaries to assist readers who have some knowledge of, but not in-depth expertise in, the area to understand important medical advances.All manuscripts are subject to peer review by international experts. Letters to the Editor are welcomed and will be considered for publication.
