Abstract: Improvement in end-of-life-care is required for patients dying with chronickidney disease (CKD). The UK government now recommends that tools such as theLiverpool Care Pathway for the Dying Patient (LCP) be used to enhance the care ofthose patients dying with CKD. The LCP was originally developed for patients dyingwith terminal cancer, however has been shown to be transferable to patients dyingwith heart failure or stroke. On this background, in 2005 a UK National Renal LCPSteering Group was formed. The aim was to determine whether or not the genericLCP was transferable to patients dying with CKD. An Expert Consensus sub-groupwas established to produce evidence-based prescribing guidelines to allow safe andeffective symptom control for patients dying with renal failure. These guidelineswere finalised by the Expert Consensus group in August 2007 and endorsed by theDepartment of Health in March 2008. A literature search on symptom control andend-of-life care in renal failure was performed. A summary of the evidence was pre-sented at a National Steering Group meeting. Opinions were given and provisionalguidelines discussed. A first draft was produced and individually reviewed by allmembers of the Expert Group. Following review, amendments were made and a sec-ond draft written. This was presented to the entire National Steering Group and againindividual comments were taken into consideration. A third and fourth draft werewritten and individually reviewed, before the guidelines were finalised by the ExpertConsensus group. Patients dying with advanced CKD suffer symptoms similar topatients dying of cancer. The Renal LCP prescribing guidelines aim to control thesame symptoms as the generic LCP: pain, dyspnoea, terminal restlessness and agita-tion, nausea and respiratory tract secretions. The evidence for the production of theguidelines is discussed and how a consensus was reached. A summary of the guide-lines is given and the complete guidelines document is available via the Marie CuriePalliative Care Institute, Liverpool website. Palliative Medicine (2009); 23: 103–110
