GB, as Donna says, most hospice care is delivered at home and that is where most hospice patients die. Think of hospice as more of an adjective than a place. The focus is palliation and a more peaceful exit. But while "hospice" can be administered by a family or an agency, the ultimate project manager should be the patient.
When my husband began to experience air hunger on 24/7 BiPAP, we obtained morphine and other scripts via our PCP and filled them as we would any other prescriptions. [Given the diagnosis, any doc that has seen you within the last year is well within professional scope to do that. There seems to be a myth in some quarters that only hospice can write morphine.] We then administered these rx according to my husband's needs.
He died a few days later, having used that time to say goodbye to the people he cared about most. If he had been unable to communicate, we still would have known what to do because we had talked about it. That is the conversation(s) that I am hoping every PALS on the Forum will have with anyone that might be standing next to your bed, and I know, GB, that you will have it with your wife. And that is your own best hospice, whether you end up working with an agency or not.
