Treatment trajectories of patients with End Stage Kidney Disease

On the occasion of the 20th anniversary of the REIN (French Renal Epidemiology and Information Network), a summary work on the contributions of the national French ESKD register was carried out. On the issue of trajectory of ESKD patients, the following key messages were retained. Apart from a few rare, absolute or relative contraindications, till date, there is no medical consensus on the indications of one treatment modality as compared to another, and therefore, no recommendations allowing defining criteria for guiding patients, based on their characteristics, to a technique/treatment modality. In addition, the patients' choices and their changing needs over time must be taken into account. Thus, due to the limitations of each of these modalities, a good number of patients with stage 5 renal failure treated with kidney replacement therapy will move between these different modalities. For many years, the REIN registry has endeavoured to represent the patient flows between the different treatment modalities. In order to better understand and then optimise the trajectories followed by patients who have reached stage 5 of their chronic renal failure, it was necessary to develop tools to model these complex trajectories where the treatment modalities are considered as complementary.
