Comprehensive conservative care: what doctors say, what patients hear

The demographic evolution of patients with advanced chronic kidney disease (CKD) has led to the advent of an alternative treatment option to kidney replacement therapy in the past couple of decades. The KDIGO controversies on Kidney Supportive Care called this approach "comprehensive conservative care" (CCC) and defined it as planned holistic patient-centered care for patients with CKD stage 5 that does not include dialysis. Although the benefit of this treatment option is now well-recognized, especially for the elderly, and comorbid and frail patients, its development remains limited in practice. While shared decision-making and advance care planning represent the cornerstones of the CCC approach, one of the main barriers in its development is the perfectible communication between nephrologists and patients, but also between all healthcare professionals involved in the care of advanced CKD patients. As a result, a significant gap has opened up between what doctors say and what patients hear. Indeed, although CCC is reported by nephrologists to be widely available in their facilities, few of their patients say that they have actually heard of it. The objectives of this review are to explore discrepancies between what doctors say and what patients hear, to identify the factors underlying this gap, and to formulate practical proposals for narrowing this gap in practice.
