Even though they might not be one of the big name hospitals, (or the oligopolies in the market) they have a successful lifetime in the market due to the high demand for emergency response. that is why the healthcare system is very unique, in most markets where there are leading businesses kind of taking charge of the market, it drastically affects the smaller or less popular businesses in the market. for example if it is a product, a lot of people will explore their options, do research, and go with the best pick, however when an emergency occurs, people don't always have that luxury therefore all hospitals get adequate business from its community.
