91 yr old patient was in hospital because of kidney failure caused by diuretics he was taking for edema caused by heart failure. He was taken off the two diuretics in hospital during his 2 week stay and put on lowest dose of one diuretic before discharge. Patient was put on hospice using company recommended by his assisted living facility in California that he returned to. The hospital Dr. discharge instructions for his medication was not followed, and he was immediately put back on the very high dosages of the diuretics he was on that put him in hospital. Died 2 weeks later. I have documentation of error.
