Patients do not have to be a "do not resuscitate" to elect hospice services. They can still be a "full code". Generally, patients and their families come to understand that
resuscitation efforts become futile when faced with terminal or life-limiting illnesses. This is an education issue that both hospice nurses and social workers address with the patient and family on admission.
The hospice philosophy embraces death as simply the closure of the circle of life. We follow the lead of the body, and do all we can to control pain and symptoms so the patient can have some quality of life. This is what we call comfort care. We do not do anything to "speed up the process". Patients and their families elect hospice services because they realize that quality of life is different (now) from quantity of life. We allow a peaceful, respectful life closure in the home setting, on their terms.
If the patient or their family chooses to call 911, that is their right. Paramedics will arrive, perform CPR, and generally transport the patient to the hospital. Hospice is an alternative to an institutionalized death, so being admitted to the hospital would require the patient to discontinue hospice services.
