That was in the Pittsburgh region. I've had patients or family members who were told the same thing here in the Johnstown area. The "catholic" physician who treated my friend Fr. Gerard told me that IVs were "against hospice policy" as they "only prolonged the process."
When my father in law was admitted to hospice care, their default order was no assisted hydration or nutrition. No one in our family told them that, and we had to specifically countermand that order.
When my mother in law was finally admitted to the in patient hospice unit in the last 48 hours of her life, her IV came with her from home. The hospice nurse made my wife feel guilty for requesting it. When my wife asked how often this nurse dealt with IVs, the nurse rolled her eyes and huffed, "We never do IVs here!"
Its going on every day across the country.
I did IV’s all the time for dehydration. If the pt has a picc line or a port placed, you can teach the family very easily how to administer IV fluids for hydration. However, I refer you back to my precious post regarding hydration during the dying process and how counterproductive, even harmful it is.
