I Live in CT and have worked at both Middlesex Hospital and Hartford Hospital. Both are Magnet Hospitals which is important to look for in my opinion. Middlesex is by far the more relaxed work environment, and much more in tune with promoting good staffing and employee development. However, it is a small hospital, so the acuity is low. You said you were looking for ICU so you may be looking for more action. In that case Hartford is the way to go. Its an innercity teaching hospital and as such is where most other hospitals send patients who are going bad. They have specialty ICU's for each type of medicine as well as step down units. I myself am just switching back to Hartford after 3 years at Middlesex. Pay is pretty comparable with all of CT hospitals. Competition is pretty fierce.
Hope this helped
