Title: A Cluster Randomised Trial of Alternative Forms of Hydration in Cancer Patients in the Last Days of Life (Feasibility Study)
Brief Summary: It is unclear whether the use of fluids given by a "drip" is beneficial to cancer patients in the last days of life, and as a result many individuals do not receive such treatment (although they do receive fluids by mouth, and regular mouth care). The researchers want to undertake a large study ("main study") to determine the benefits of fluids given by a drip, but first need to undertake a small study ("feasibility study") to ensure that the main study can be done.

The feasibility study will be done in twelve units (hospitals, hospices) in England \& Wales; each unit will be allocated a treatment at random, and all patients in the unit will receive that treatment (if appropriate). Standard treatment A consists of drinking fluids (if possible), regular mouth care, and treatment of any symptoms; standard treatment B consists of drinking fluids (if possible) , regular mouth care, fluids by a drip, and treatment of any symptoms.

Patients will be assessed on a four hourly basis, and any uncontrolled symptoms will be recorded. The main symptom of interest is agitation ("delirium"), which has multiple causes, including dehydration and kidney failure. Uncontrolled symptoms will be appropriately treated, e.g. patients with pain will be given painkillers. Equally, problems relating to the fluids given by a drip will also be recorded. Involvement in the study will not interfere with the patient's general care, and there will be no additional blood or other tests.
