My brother was healed completely and miraculously as a teenager after we were told time and time and time again to prepare for the fact that he would die within a couple of years, starting when he was an infant. The diagnosis and treatment was by the top Cystic Fibrosis specialist in the east and multiple physicians in the top hospital in West Virginia. He was given a number of treatments and physical therapy daily for his life up until then. God answered prayers and healed Him all by Himself. The details of which many churches have heard to encourage their faith. For that alone, I would expect him to exclude any faith in hospitals.
There were many other miracles, but that was a personal one he experienced. He is an adult and there has been no relapse. There is no medical cure for CF.
God gets all the credit and glory.
