According to the Act on Patient Insurance, participants in a scientific study who suffer damages in connection with a study generally have the same right to compensation for their damages as other patients.

When the Act on Patient Insurance does not apply to benefits for participants in a scientific study, researchers are generally required to purchase special insurance for participants if participation in the study involves risk.

Before granting a permit for a study, the national bioethics committee or other ethics committee examines whether appropriate guarantees are available for participants. Participants in a scientific study may obtain information on guarantees from the study sponsor or from the ethics committee that granted the study.
