This article describes communication and information between patients and health staff in the Danish Health Service. A number of laws, regulations, rights, and rules have been passed, and in 1998 a new law came into effect concerning patients' rights in the health service. This law protects the rights of patients and provides the health staff with guidelines on communication and information to patients. An analysis of the law is given here. Each profession in the health service has its own regulations and ethic rules. These regulations and rules are reviewed with respect to communication and information in the Danish Health Service.
