Hospital ethics policy for medical futility in unconscious patients

Although, physicians have a duty to treat their patients, sometimes the cure is not possible in medicine and there is no result in attempt to cure patient. In this situation, we face with two types of patients: first, patients who are conscious but suffering with advanced disease and will survive only for a short time. The second group, are patients who are unconscious and may not be cured with the standard treatment based on physician experience.
The latter are the subject of the present article. So what a Hospital should do in dealing with these patients? How the hospital, should develop a community-based policy on providing care for these patients. Finally, how should inform the public to adhere to these policies.
