Background:In rheumatoid arthritis (RA) care, patients and professionals face treatment decisions regularly due to the high number of treatment options, the chronic character of the disease and challenges around multi-morbidity. Recent studies have underlined the added value of shared decision making (SDM) between patients and professionals in RA care for health outcomes (i.e. disease activity, pain and joint damage) 1-4. Therefore, effort is needed to facilitate the implementation of SDM in daily clinical practice in order to advance patient centred RA care.Objectives:The aim of this implementation project was to improve SDM about treatment options for patients with RA. In addition the use of (Patient Reported) Outcome Measures in the process of SDM was taken into account.Methods:An implementation programme was developed by the National Association ReumaZorg Nederland (RZN) in co-creation with patientpartners and RMD professionals. Three hospital departments of rheumatology in the Netherlands participated in the project between January 2020 and March 2021. The implementation of SDM was supported by a project team of RZN.Results:The implementation programme started with the recording of RMD consultations in three participating departments of rheumatology. The consultations were then evaluated on the process of SDM (OPTION5) and discussed during the training of professionals that followed. Three observed improvements in SDM in RA care were: a. A more explicit introduction of choice for a patient is needed during the consultation; b. Tasks within the process of SDM should be allocated clearly among RMS specialists and nurses working together, in order to avoid unnecessary repetition of the same - or even inconsistent information; c. Besides the use of (patient reported) outcome measures in the SDM process, it is also important to include patients’ values (what matters to them?) when deciding on the best fitting treatment option. After the training, implementation support for SDM was given and aids to support the SDM process (i.e. redesign of health care processes, task allocation, hand card with explanation of the 4 steps of SDM) were developed. The implementation programme was tailored to the needs and stage of change for each hospital. Implementation materials for the hospital teams were developed in co-creation with patientpartners and the professionals. At the end of the project, a second set of consultations was recorded and evaluated on SDM. The hospital teams concluded that a continuous improvement cycle is needed to further enhance SDM.Conclusion:A continuous implementation programme on shared decision making could stimulate the enhancement of patient centred care in daily practice. Patient organisations could take a significant role in such a programme.References:[1]Pablos JL et al. Patient. 2020 Feb;13(1):57-69.[2]Fautrel B et al.
