Negligence

Today at work, I was forced to report negligence towards an elderly patient. I feel very sorry for this situation. This is the third time I have seen the same patient in a very short period of time. He always comes in a very poor state of hygiene. It is sad. His family doesn't seem to give him any of the medications necessary, they do not follow our orientations, and most of all they refuse to put him into a home.
They say they have to work and cannot watch him during the day, which is why now he is filled with pressure sores from his occipitus down to his ankles, they do not give him his medications that was prescribed because besides the fact that it is expensive, that will make him evacuate more often (which in fact is part of his treatment), and diapers are expensive as well. Today he came in with two diapers, which the nurse explained to me, make them last longer for the contents of one diaper will spill onto the other.
The most outrageous fact of all is that the family always is hard demanding on the whole staff to watch out for this patient: he is so sick, this is absurd, how could the let him go out of the hospital in this state. He always goes home a little bit better, but a few days later comes back a total wreck.
Which is why I made the choice of reporting him. Doesn't this run away from the medical-patient relationship? Should I have confronted the family more before doing this?
