Decision-making in healthcare regarding patient care is based on evidence, which is the best multi-faceted knowledge and information available. The information sources to be used are research-based knowledge, customer/patient preferences and expectations, information on the situation and resources of the care context and professional knowledge. Like in other countries in Finland, the evidence-based practice has its roots in medicine and in the interdisciplinary (multidiscipline) and multi-professional collaboration for gathering evidence for organizing healthcare and services for patients.
