This is just one personal anecdote, but my son broke his wrist last spring running around in the park after dark. At first he insisted he was fine, so we didn't end up going to the JCMC emergency room until after midnight. Being late, it wasn't too crowded, but they also didn't seem to be all that well-staffed. And someone came in with a gunshot wound and someone else came into the waiting room in labor, so we weren't the priority.

At 4AM I decided my kid needed some sleep, so we went home and went to urgent care in the morning. They wrapped him up and sent him to an orthopedist in the suburbs who put him in a cast, all in less time than we sat in the waiting room at JCMC.

So, moral of the story is less that JCMC is bad, and more that, don't go to the emergency room unless it's life-and-death. Odds are you're going to get better care and faster from urgent care.
