"Research consistently shows people prefer to die outside of hospital," said Louise Sharpe, Professor of Clinical Psychology at the University and lead author of the study recently published in the Journal of Clinical Oncology.
"Dying in a non-hospital environment also means savings for our health care system."
"This is the first study to show that providing incurable cancer patients with detailed information about signing do-not-resuscitate (DNR) orders leads to fewer patients ending their life in a hospital."
The high profile death of terminally ill Sydney woman Aina Ranke last week highlighted a case of someone wishing to control their death. Many people may not choose to completely control their deaths, as Ranke did, but increasing numbers don't want to be revived if they go into cardiopulmonary arrest, a common cause of death for cancer patients.
"Terminally ill patients require resuscitation in the event of cardiopulmonary arrest, unless they have a DNR order," Professor Sharpe said.
Up to 67 per cent of patients with terminal cancer who were admitted without a DNR order were administered cardiopulmonary rehabilitation (CPR), with less than five per cent surviving the admission.
"Research shows that terminally ill patients who receive mechanical ventilation are less likely to survive the admission," Professor Sharpe said.
Late DNR orders often result in increased hospital costs and patients receiving inappropriate life-sustaining treatments.
While it is recommended doctors raise the issue with patients early there is no national policy or standardised information on DNRs. In practice there are wide variations in how early a patient is told about the orders. Few patients in the study had already discussed it with their doctor.
"Our study showed that actively informing patients about their DNR options led to earlier DNR orders being made compared to a control group who were not offered that information," Professor Sharpe said.
One hundred and twenty Sydney patients with incurable cancer and a prognosis of three to 12 months took part in the study. The intervention regarding DNRs was a discussion with a psychologist and an information pamphlet. Nineteen per cent of the intervention group died in hospital compared with 50 per cent of the control group.
"Importantly, those who were invited to think about the circumstances and given information were not made more anxious or depressed by the intervention," Professor Sharpe said.
"This is consistent with the literature showing that discussion of end-of-life topics is not harmful to patients."
