In cooperation with the Maastricht University Medical Centre and Equalis Strategy & Modeling we will investigate whether the use of outcome information (patient reported outcome measures) can stimulate Deciding Together. To this end we are developing a patient platform where outcome information is fed back. In addition, an information package will be developed for doctors and patients with information about ‘shared decision making’ and possible treatment options. By evaluating the discussions between doctor and patient, we will gain insight into the promoting and hindering factors of shared decision-making with patients with back complaints and into the use of outcome information in daily care practice.
