"Eight Norwegian rehabilitation centers (clusters) in secondary care participated, comprising five rehabilitation institutions and three hospital rheumatology departments. The centers started simultaneously to include patients in the control condition (delivering current rehabilitation) before they one after another introduced the BRIDGE-intervention in a predefined, randomized order. Accordingly, the intervention was rolled out in sequences with an initial period in which all centers provided usual care (control), and a closing period in which all centers provided the BRIDGE-intervention to patients (). The study was registered in ClinicalTrials.gov (NCT03102814) prior to launch."
