Presentation
I am a research manager at Kela’s Research Unit, and I am conducting register-based research particularly on medicines and the pharmaceutical sector from a societal perspective. I am responsible for the research related to the Kanta services. I also support other researchers in the use of data from the Kanta services’ Prescription Centre. In addition to research, my work includes expert tasks related to medicines and the pharmaceutical sector, such as evaluation statements on the reimbursement of medicinal products and their reasonable wholesale prices.
Expertise
- register-based research on the prescribing and use of medicines
- research on medicine life cycles
- research on the Kanta services (especially research on the electronic prescription service)
- reimbursement system for medicine expenses
- health economic evaluation
- medication of the elderly
Ongoing research projects
