Doctor (career) Frustrations

I wonder why there are so many npcs working at the police station and just 3 (mostly) useless npcs at the hospital, sometimes at least one of them cleans the mess. It sucks because there's the workers area/gym/cafeteria but no one really uses, there's no sense of a hospital team. I wish they had made the assistant "ask" the incoming patients to sit and wait and they would watch tv, buy drinks, use the bathroom, etc There are actually plenty of seats and nobody uses them, sims are sick but do not sit. :| I could use a npc help to admit patients as long as there are available beds. It really is frustrating specially because EA gave that game Theme hospital and you keep wishing that GTW gameplay was more like it.
As if it wasn't already bad that our sims can't visit the hospital to get treatment(when we're playing w/them), when we get to visit a patient at their homes it doesn't matter if you have played sims living at that house, they fill the place w/the same random npcs that were already in a hospital bed before you left to visit patients. It super annoying, we get to see our sims owners of the house and the random homeless npc wandering the lot waiting to be treated. O.o' Idk what's worse, this or that crime scene in the detective career always happens in the same house.
