Postmarketing surveillance plays a pivotal role in identifying previously undetected adverse events (AEs) that emerge when a drug is used in broader and more diverse patient populations. However, traditional methods of updating drug labeling with new AE information have been manual, time consuming, and error prone. This paper introduces the LabelComp tool, an innovative artificial intelligence (AI) tool designed to enhance the efficiency and accuracy of postmarketing drug safety surveillance.

To achieve this, training, including short-term training (STT) activities, at various levels is required. This article aims to describe the experiences of the authors during the development and implementation of STT in an attempt to improve the PV training landscape of these countries. To identify gaps, a baseline assessment of PV teaching and practices at the national medicines regulatory authorities (NMRAs) and medical universities was conducted. Five successive training sessions, tailored to each country's specific needs and regulatory environments, were conducted; three focusing on fundamental concepts in PV and two dedicated to training-of-trainers courses. The training targeted staff from PV units of the NMRAs and medical universities. Enabling participation from all four countries in the same training fostered cross-country learning and collaboration. The contribution of STT to university education and the operational methodologies within NMRAs are explored, showcasing the impact on knowledge transfer and skill development in each country. In conclusion, by investing strategically in STT activities and fostering partnerships with academic institutions and NMRAs, we demonstrated a sustainable approach to PV capacity strengthening in resource-limited settings.

Spontaneous reporting databases frequently report unresolved outcomes for gustatory, olfactory and auditory (GOA) ADRs. However, such a high volume of unresolved GOA ADRs could reflect an under-investigated clinical issue or an intrinsic difficulty in the outcome assessment.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objectives: &lt;/strong&gt;The objectives of the study were: (1) to investigate whether unresolved outcomes are reported more frequently for GOA ADRs than for other ADRs to systemic antibiotics and (2) to identify possible signals of unresolved GOA ADRs for systemic antibiotics.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;We used the EudraVigilance database to extract the number of ADRs to systemic antibiotics of the Anatomical Therapeutic Chemical class J01 up to February 2019. We classified ADRs in \"non-GOA ADRs\" and \"GOA ADRs\". Adverse drug reactions were categorised in three groups according to the outcome: defined, persistent/permanent (unresolved) and undetermined ADRs. We performed disproportionality analyses with the case/non-case methodology, by calculating the crude reporting odds ratio (ROR) and 95% confidence interval (CI). Cases were all persistent/permanent ADRs, and non-cases were defined and undetermined ADRs. For the first objective, index groups were gustatory or olfactory or auditory ADRs, while reference group included all non-GOA ADRs. For the second objective, we performed a disproportionality analysis by using the sub-set of GOA ADRs. Index and reference groups varied with subgroups of drugs and drug class, so that each drug and drug class was compared with the others. We conducted two sensitivity analyses for each analysis by varying the case definition.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;We extracted 748,798 ADRs, including 10,770 GOA ADRs.

Olfactory ADRs were reported more frequently as unresolved for doxycycline (ROR: 2.4, 95% CI 1.26-4.58, p = 0.0078) and levofloxacin (ROR: 1.92, 95% CI 1.28-2.86, p = 0.0014). Auditory ADRs were reported more frequently as unresolved for doxycycline (ROR: 1.52, 95% CI 1.09-2.12, p = 0.013) and clarithromycin (ROR: 1.31, 95% CI 1.09-1.59, p = 0.0049).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;We tested and used an appropriate expected frequency standard, which allows us to identify possible signals of unresolved GOA ADRs","PeriodicalId":11382,"journal":{"name":"Drug Safety","volume":" ","pages":""},"PeriodicalIF":4.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142603784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
