The scheme, called the Liverpool Care Pathway (LCP), was designed to reduce patient suffering in their final hours.
Developed by Marie Curie, the cancer charity, in a Liverpool hospice it was initially developed for cancer patients but now includes other life threatening conditions.
It was recommended as a model by the National Institute for Health and Clinical Excellence (Nice), the Government’s health scrutiny body, in 2004.
It has been gradually adopted nationwide and more than 300 hospitals, 130 hospices and 560 care homes in England currently use the system.
Under the guidelines the decision to diagnose that a patient is close to death is made by the entire medical team treating them, including a senior doctor.
They look for signs that a patient is approaching their final hours, which can include if patients have lost consciousness or whether they are having difficulty swallowing medication.
