Rheumatoid arthritis (RA) is one of the most frequently occurring autoimmune rheumatic diseases, affecting an estimated 1% of the global population. RA is a chronic inflammatory disease that leads to the development of synovial inflammation and effusion, ultimately followed by joint destruction and permanent disability. The substantial socioeconomic burden and the challenge of RA patients adhering to treatment is an important factor of this disease and its impact on both patients and society. An innovative approach is needed in order to find new ways to assist and truly empower patients to understand their disease, increase compliance and thereby increase quality of life. There is a discrepancy in the understanding of what's of importance when living a life with a chronic disease. The importance of patients' perspectives concerning disease- and treatment related impacts, is of crucial importance when involving patients in decisions about treatment, and to support the patients in optimal medication-taking behaviour to ensure patient health and reduce health care costs. There are still unmet needs that have a huge impact on quality of life (QoL) such as fatigue, pain, sleep and psychological issues, etc, which need to be taken seriously as these can have severe and debilitating consequences for the individual. The aim of this study is to investigate and evaluate the effects of the digital app RheumaBuddy4.1 (RB4.1) and the ability to provide support and increase quality of life in patients with RA
