My experiences were at a Catholic hospital (hospital of choice where we lived in CT). No Jewish or government hospitals in the area and far better care than the university affiliated hospital.
As a family law trust attorney I dealt with hospices and associated issues for decades and did not run into what you experienced.
Certainly at the Catholic hospital every effort is made to keep the patient alive as long as possible.
It is terrible to be put in the position to discontinue further medical procedures. It happened to me with the late Mrs. CTL. After coding three times in a few years, 140 surgeries, a dozen long term ICU stays in comas in life support, we were presented with one final medical procedure that could be attempted. Both the surgeon and nephrologist agreed with my observation that she could not survive the procedure. 100% medical opinion that she would die on the table in pain.
Decision made to start hospice care in ICU, remove artificial life support and let her die with me and daughters in dignity. Small doses of morphine to handle pain (not hasten death), she passed in two hours with no further suffering.
The medical establishment would have been happy to keep billing insurance for things that could not have saved her life. Hashem had a way of let us know her time on earth was up
