Janne Petersen

Janne Petersen is an Associate Professor in the Section of Biostatistics within the Department of Public Health at the University of Copenhagen's Faculty of Health and Medical Sciences (SUND). Her research leverages Denmark's comprehensive national health registries to analyze healthcare utilization, costs, and patient outcomes across multiple disease areas.

Her primary research interests include:

• Biostatistical methodology for registry-based epidemiological studies
• Real-world impact of novel cystic fibrosis therapies (elexacaftor/tezacaftor/ivacaftor) on hospitalizations and treatment patterns
• Cardiovascular disease management pathways and economic burden of myocardial infarction
• Socioeconomic consequences of renal replacement therapies

Analysis of her 2025 publications reveals a strong focus on comparative effectiveness research within universal healthcare systems, particularly examining how new treatments alter resource utilization while maintaining safety. Her work consistently employs large-scale Danish registry data with international collaborations, demonstrating methodological rigor in observational study design.

Dr. Petersen maintains active clinical-academic partnerships with major Danish hospitals and international research consortia including the TransformCF Study Group, with recent work extending to Australian healthcare systems. Her research directly informs health policy decisions regarding high-cost specialty pharmaceuticals and chronic disease management.
