@gingerw this is true, they do each have their own strengths. For my knee replacement I did not go to MGH, I went to Brigham and Women's which is a "partner hospital" with MGH. My ortho there is wonderful and I wanted him to do the surgery.
Here I am, not that far from Boston, but I consider the hospital care here to be horrible after having been in there about 3 times prior to my liver transplant. I hope to never have to go there again. I told my husband if I was ever in an emergency situation to get me there and then have them send me by ambulance to MGH. Interestingly, I have been through the ER department there and I thought they were good. It's just their inpatient care that is sadly lacking.
