What is a Ceiling of Care?
This means that doctors should engage with the patient, those close to them and the healthcare team in order to determine what level of treatment is appropriate to give to a specific patient towards the end of their life.
Some treatments can be limited by a ceiling of care plan e.g CPR, limiting what ventilation may be given (e.g. non-invasive, invasive or none), and limiting life-prolonging drugs (e.g. antibiotics). In addition, the decision not to provide artificial nutrition (e.g. via PEG tube) may be taken.
What is an advance statement?
An Advance Statement is sometimes called a “Statement of Wishes and Care Preferences”. It allows an individual to make general statements about their wishes, beliefs, feelings and values and how these influence their preferences for their future care and treatment.
What is an advance decision?
