Learning from my spouse who is a current medical resident -- some attendings admit and discharge more patients than the capacity because their bonuses are tied to that. That is a twisted incentive and it is in conflict with ACGME's guidelines of not letting residents handle more than 10 patients at a time. The attending/hospitalist at my wife's hospital makes $420K/year + bonus (it's near Miami, FL). They work 8-hours shift for 7 days and then rest 7 days. If one chooses to, s/he can moonlight at another place (a senior friend of my wife works for a hospital in Palmdale, CA and another one nearby for 7 days each; she easily bags $600K/year; she is raking in money when she can work this much while buying houses, and she plans to work half as much in a few years).
I also wonder if hospitals like "The People's Hospital" make patients sign waiver to not sue them. At my wife's hospital, some of the patients (and/or their families) are obviously angling for lawsuit and are always looking for excuses to do that. That legal/liability burden (among may other things like doctor's salaries; bloated administration; etc.) is part of the reasons why hospital bills are exorbitant.
