Milton Keynes Hospital will undergo a three-day inspection by health chiefs in October.
A team from the Care Quality Commission will visit eight key service areas - A&E, medical care (including frail elderly), surgery (including theatres), critical care, maternity, paediatrics, end of life care and outpatients - from October 21-23.
They will be judging if services are safe, effective, responsive, caring and well-led, using a variety of methods including observation, interviews, listening events with staff, patients and local people, and reviewing policies and other documentation.
Hospital chief executive Joe Harrison said: “I look forward to welcoming the Care Quality Commission to our hospital and giving our staff the opportunity to demonstrate their commitment to providing safe care and a good experience to the thousands of patients we see each week.
“We are developing and improving our services all the time, and although we know there is more to do, teams across the hospital have achieved a great deal and work incredibly hard to give every patient the kind, compassionate and professional care they expect and deserve.
“We will take the opportunity through September and early October to ask staff, patients and the local community to talk to us about their experience of care and treatment at the hospital to help us learn when things haven’t been as good as they should have; and to hear about what people really value about their hospital.”
