Narrator: This is Science Today. A new study from the University of California, San Francisco found that heart attack patients die at a higher rate when the nearest emergency room is so overcrowded that their ambulance is diverted to another hospital.
Hsai: This is one of the first studies to actually link how crowding affects outcomes. We were able to show that patient mortality, whether we measure it by 30-day, 60-day, nine-month or one-year, mortality increases when you've been experiencing diversion. So, when your ER is crowded, essentially.
Narrator: Emergency room physician Renee Hsia explains that ER crowding is actually a downstream effect of hospital crowding and could be prevented through better overall management of resources.
Hsia: ER crowding isn't just an ER problem. It's a hospitalwide problem. A lot of the time, we're crowded in the ERs because there's no inpatient beds. So, I think it's important to note that there are policy initiatives that can be made but they can't just be at the ER level, they have to be whole hospitalwide solutions.
