The purpose of this collaborative project between “Center for person-centered care” and RISE was to develop an audit that form the basis of a certification process and to analyse organisational prerequisites and obstacles for a certification process. As a support to organizations, the standard “Patient participation in healthcare – minimum requirements for person-centered care” has been developed. It aims to facilitate cooperation between patients and healthcare professionals in the design, execution of care, implementation, and evaluation of healthcare services. In the standard, participation is both about the individual's participation in their own care, and about patient participation at the organizational level. The Standard can be used as an aid for planning, management, implementation, and systematic evaluation of daily activities, and enabling patients to manage their daily lives and empower them in the care process. In addition, it can be used to support patient participation at the system level and thus ensure that the patient perspective is included in the development, implementation and evaluation of services, research, and policies in healthcare. A certification based on the standard gives service providers the opportunity to increase its efficiency and quality regarding the person-centred care that patients receive. A certificate of patient participation in healthcare shows that a healthcare organization has implemented the working methods according to SS-EN 17398 and that it has been reviewed and approved by a certification body.  What did we learn? How can we use the standard in implementation of the participating aspect of person-centred care?
