I prefer Elliot to CMC just because they have access to more support imo. The Elliot is part of SolutionHealth which is loosely affiliated with Mass General Brigham iirc.

That said Boston has some of the best teaching hospitals in the world such as MGB, Beth Israel Lahey, and tufts. These health systems provide over 50% of care for Massachusetts and offer their own insurance plans through MassHealth, which may contribute to higher cost of care. Also, as specialty care becomes better further outside of city centers, it reduces the need for acute care in those areas, to a degree. Therefore, these health systems can justifiably funnel acute care patients into higher cost beds around Boston. I'm not saying that it's a bad model, but I can see why some people worry about it. And I'm certainly not a billing & insurance wizard, so if someone has more info please correct me. /Rant

If I had an acute life-threatening illness or trauma there's no doubt I'd want to go to Boston. No knock on Dartmouth, which is a level 1 trauma center and has a great reputation with the med school and Colby-sawyer nursing.
