Changes to the way diagnostic tests and screening are carried out in Cheshire and Merseyside mean many more tests are being carried out in more centres around the region. A system-wide transformation programme has streamlined processes and introduced a new, flexible staffing system, while improving access to tests for patients. Guests Liz Bishop and Dr Ash Bassi explain how the transformation is being carried out, in conversation with Caroline Kenyon. Liz is Chief Executive of The Clatterbridge Cancer Centre NHS Foundation Trust and lead for the Cheshire and Merseyside Diagnostic Transformation Programme; and Senior Responsible Officer for Cancer in Cheshire and Merseyside. Ash is a consultant gastroenterologist at St Helens and Knowsley NHS Foundation Trust; Clinical Lead for the Cheshire and Merseyside Endoscopy Network; and North West Transformation Lead for Endoscopy.
