This study is exploring symptom burden, health experiences and expectations of treatment and survival of seriously ill dialysis patients and their physicians.

Sharing and communicating information with patients is an integral part of medical care, yet research has shown that disparities exist between physicians and patient perceptions of illness severity. In renal medicine, along with many other specialties, expected prognosis can affect treatment offered.Thus appreciating and understanding one's prognosis can influence patients and relatives' expectations for treatment and guide discussions regarding quality of life.

Previous work has highlighted disparities in the United States between expectations of survival of seriously ill haemodialysis patients and their physicians. The investigators plan to repeat this study within the United Kingdom, to see whether similar issues occur and to elucidate current practice on discussions of prognosis, symptom burden and transplant candidacy. The investigators hope to identify where care can be improved and to enable patients to better make informed decisions on treatment and goals of care.

Part one of the study is to repeat this study in haemodialysis patients in the United Kingdom. This has been completed and published (2021) at https://www.kireports.org/article/S2468-0249(21)00103-0/fulltext.

Part two of the study is to extend the study to peritoneal dialysis patients in the United Kingdom.
