Macmillan Cancer Support has launched an online toll allowing newly-diagnosed bowel cancer patients in England to see how other patients rated local hospitals.
They will see feedback from other patients, ranging from whether they felt they were treated with dignity to how high car parking charges are.
It is intended to help inform decisions about treatment, and where to have it, the charity said.
After an initial six-week trial, which started on 21 June, it hopes to introduce the tool for other specific cancers and into other parts of the UK.
Ciarán Devane, chief executive of Macmillan Cancer Support, said: “More people are being given the option to choose where to have treatment – and thanks to Macmillan’s tool, bowel cancer patients will be able to make that decision based on information from people in exactly the same position as them.
“We want to drive standards up in hospitals,” he said. “Allowing patients to see how their nearby hospitals are rated by others who have fought the same illness as them makes this not only a valuable information tool but it’s also deeply reassuring at what can be a very confusing time.”
