If you're on hospice, you're typically at home, with a caregiver coming by once or twice a day to see how you're doing, clean up, etc., and to check on the automatic IV drip machines. These machines come with a remote that lets the patient request additional pain meds, and they're supposed to have limits on how often the button can be pressed in a certain time period. But if you're on hospice, with stage IV pancreatic cancer or other no probability of survival and extremely painful illness, those limits are sometimes not set.

When my grandmother was in hospice care at home, there were bottles of liquid morphine in her refrigerator. Her family was free to administer it as needed, for pain.
