Based on the results of step 1 and 2, a tailored implementation strategy will be developed to increase the adherence to the recommendations. The different implementation elements will be tailored to the barriers and facilitators found and will probably combine interventions directed at professional and organizational level. This strategy will be implemented and evaluated in a feasibility study. The study will be performed in 3 hospitals where the effect of the implementation strategy, the adherence to the developed indicators will be measured. A process evaluation will be performed to study the experiences of the clinicians and patients with this strategy. A cost analysis of the tested implementation strategy will take place.
