So very sorry for your loss, my heartfelt thoughts and prayers to you and your family. My brother-in-law, too, passed within 24 hours of being taken to a hospice house. I don't think it's all that uncommon. I was sad the staff didn't get to know him as he was quite a hoot, but otherwise it was the best situation, I think. My mother-in-law passed at home and it took a serious toll on several family members - difficult to be a caregiver when what you really need is to be a daughter or son.
My sister is a home hospice nurse (angels on earth) and still (after much discussion and due diligence) my father spent his last few weeks in a hospice house. We all have tough choices to make and we do our best. I know I can live with the choices I made, knowing we did what was best for all in the situation we were given. I'm fairly certain my step-mother is still with us today because of the choices made, and more than likely we were saved from finding my father fallen on the floor (or down the stairs). I also know he had the best care possible at the hospice house, including a lift so he could be moved from bed to chair at least once a day. Medications for pain were also more appropriately provided.
Again, so sorry for your loss.
