Not sure if this is what OP means, but I think it’s that residencies at Jackson/UM are notoriously difficult. The hospital here is not an academic ivory tower by any stretch - it’s a county hospital that is serving a gigantic underserved population. This has pros and cons, but it means the hours can be long, the system somewhat inefficient, and the patients not always the most rewarding.
Personally I’d rather have a training site that is up to its ears in sick patients (like Jackson) because it’s a place where med students can actually have a roll in patient care.
And while treating the same homeless guy for alcoholic pancreatitis 4 Times in a month can be infuriating, helping someone in need, who really has nowhere else to go is profoundly rewarding. The other day I helped one of my patients get a Jackson card (free healthcare for those in need) so they could have a hysterectomy for painful uterine fibroids. You won’t see that stuff in a lot of places.
