When I realized that I needed help with my mom, I had to keep on the doctor and had a sit-down consultation about hospice and/or home health. But, just a few days prior to that, I personally called hospice. It was definitely a hassle for the first several weeks ... coordinating between the doctor's office and hospice, but once he signed off on it, the ball really got rolling. It does sound like your husband may qualify for hospice as he is condition seems to be progressing more rapidly now.
I know how it feels to have a telephone glued to your ear for what seems like forever. But, please, don't give up. Sometimes you really have to hassle them to get the results and help you need and your husband deserves.
Keep in touch, and take care.
