Learning about the practice of peritoneal dialysis.

Observational studies are valuable and provocative. We are learning about how we practice peritoneal dialysis (PD) and how we might improve on that practice. For example, outcomes of PD therapy are not worse in large patients. Perhaps this will encourage physicians and patients to utilize PD in large patients. In addition, better descriptions of how we practice will help to identify systematic barriers to the advancement of home dialysis.
