Study setting
The study is being conducted in nine general practices in rural areas of Rhineland-Palatinate, Germany. GPs interested in participating in the study were invited to apply and were selected by the project team of Catholic University of Applied Sciences (CUAS). The main criteria for selection were the number of suitable multimorbid patients and the willingness of the practice to implement the intervention. The number of treatment cases in the participating general practices ranges between 2000 and 6000 patients per quarter. Approximately 30% of them are multimorbid. With the size of the practice, we have ensured that the number of potentially eligible patients is sufficient to achieve the number of cases targeted in the study.
