On 23 September, the Nordic Health Data Summit 2026 brought together policymakers, researchers, experts, and other stakeholders in Oslo to discuss how Nordic health data can be used more effectively for research, innovation, and better health outcomes. Peter Olteanu represented PharmaSafe in the NOR-OMOP session, where he presented the group’s work on mapping Norwegian drug product identifiers to the OMOP common data model.

The end of summer was a busy period for PharmaSafe, bringing together researchers for collaborative work at the iAPOGEE Hackathon before continuing to two major international meetings: the 42nd Annual Meeting of the International Society for Pharmacoepidemiology (ISPE) in Milan, Italy, and the 37th Annual Conference of the European Network of Teratology Information Services (ENTIS) in Leiden, the Netherlands.

A new international study used data from 14 EUROmediCAT registries to identify and prioritize possible medication safety signals in pregnancy. The study applied the Information Component–Bicluster–Bayesian Hierarchical Model (IC-Bic-BHM), a relatively new signal detection method for pharmacovigilance.

PharmaSafe attended the joint NordicEpi & NorPEN Conference in Tromsø, Norway, held 3–5 June 2026.

PharmaSafe is pleased to welcome a new affiliated guest researcher for 2026, Lin-Chieh Meng. Lin has already been collaborating closely with Professor Hedvig Nordeng on projects in perinatal pharmacoepidemiology, and is currently a PhD student in Epidemiology at the University of Pennsylvania.

On 12 February 2026, researchers, students, and industry partners gathered at Ole-Johan Dahls hus for the seminar “Real-World Evidence on Pharmaceuticals – capitalizing on Norwegian health data”. The event highlighted the breadth of real-world evidence (RWE) research at the University of Oslo, spanning drug utilization, effectiveness, and safety studies of pharmaceuticals and vaccines.

The 6th Nordic RWE & AI Conference, held in Helsinki on 27–28 January 2026, showcased several developments highly relevant to pharmacoepidemiology and ongoing work using Norwegian health registry data.

On 28 January, members of our research group had the pleasure of attending Sanitetskvinnene’s annual fastelavnsverksted—a festive and meaningful event celebrating 80 years of the beloved fastelavnsris tradition. Representing the group were Professor Hedvig Nordeng, Professor Anne Gerd Granås, Research Coordinator Maren Mackenzie Olson, and PhD candidate Akhila Reddy.

Our research group is proud to announce two recent publications that provide important insights into medication use during pregnancy in different clinical contexts.
