A multidisciplinary group of researchers and clinicians met in October 2018 to identify evidence and address controversies in potassium management. Here we provide our overview of potassium homeostasis in health and disease and guidance for evaluation and management of dyskalemias in the context of kidney diseases, and indicate research priorities.

The International Society for Peritoneal Dialysis last published a guideline on prescribing peritoneal dialysis (PD) in 2006. This focused on clearance of toxins and used a measure of waste product removal by dialysis using urea as an example. This guideline suggested that a specific quantity of small solute removal was needed to achieve dialysis 'adequacy'. It is now generally accepted, however, that the well-being of the person on dialysis is related to many different factors and not just removal of specific toxins. This guideline has been written with the focus on the person doing PD. It is proposed that dialysis delivery should be 'goal-directed'. This involves discussions between the person doing PD and the care team (shared decision-making) to establish care goals for dialysis delivery. The aims of these care goals are (1) to allow the person doing PD to achieve his/her own life goals and (2) to promote the provision of high-quality dialysis care by the dialysis team. Key recommendations 1. PD should be prescribed using shared decision-making between the person doing PD and the care team. The aim is to establish realistic care goals that (1) maintain quality of life for the person doing PD as much as possible by enabling them to meet their life goals, (2) minimize symptoms and treatment burden while (3) ensuring high-quality care is provided.

3. To reach a consensus that should be given to nephrologists and their patients about the length of time that is advisable to remain on PD. GUIDELINES FOR EPSGuidelines on the topic of EPS have been issued by the Japanese Society for Peritoneal Dialysis (8), the UK Renal Association (9), and the Dutch EPS Registry (10). When reading the guidelines, it is clear that issuing evidence-based guidelines on EPS is being hampered by:

This is the first study to analyze the association between training characteristics and outcomes in a large cohort of PD patients. Low training time (particularly <15 h), smaller center size and the timing of training in relation to catheter implantation were associated with a higher incidence of peritonitis. These results support the recommendation of a minimum amount of training hours to reduce peritonitis incidence regardless of the number of hours trained per day.
