Conflicts will arise. I brought in a nurse to support me, and eventually ignored their criticisms and did what I felt was right, according to my and his physician's standards. Don't take things too personally. Your parents should indicate if they prefer hospice in their living wills. I agree with the authors that hospice is a compassionate and dignified approach to care for those who are dying.
Hospice can be in a private facility or at home.
My dad was at his mother's house, where he had lived before the illness, so he felt comfortable. We all had to pitch in and it was taxing. But the hospice service we used also sent a nurse every other day to check in on him and his medication supply. The nurse also taught us things, such as how to administer medicine and the signs of imminent death. Also, the hospice priest helped my dad sort out some issues and to forgive himself and others for past mistakes.
