I don't like to reveal too much about myself on the web but I'll make an exception:
If Atlanta is anything like Boston (where I worked) Grady almost certainly got some,if not many,prisoners as patients.That was certainly the case in Boston...Boston City Hospital (renamed "Boston Medical Center" some years ago) certainly got prisoners as patients,particularly from the Suffolk County lockup...only a couple of miles away.But,as I noted,my hospital...a very "private" one...also received such prisoners,including from Walpole State Prison (AKA: "Cedar Junction"),the home of the state's nastiest criminals.
It seems to me that the location of the state's large prisons could be a factor.Walpole State Prison is located within easy commuting distance of Boston.Georgia is a much bigger state so the same might not be true there.
But one thing I can guarantee is that regardless of distances involved hospitals like Emory would,at the very least,have an agreement with the Georgia Department of Corrections to provide care for the sickest,most "complicated",patients.
Well, to get more specific - Dekalb Medical (formerly Dekalb General) would actually be the public hospital for DeKalb County. Grady is in Fulton County (Atlanta), while the criminal was in Gwinnett County. So the counties would take their prisoners generally to the local county facility. The State prisoners are pretty well spread out. The big prison is at Reidsville (Savannah is the closest major city); death row is at Jackson (halfway between Atlanta and Macon). I don’t think there is a state prison in either Fulton or DeKalb counties.
In addition to its own hospital, Emory also trains doctors at both Grady and the VA in Atlanta. The State med school is in Augusta. Mercer (Baptist) has its med school in Savannah. And there is a med school for Blacks in Atlanta (Morehouse, Baptist).
