An affiliated hospital is a hospital where a doctor can practice and admit patients. A doctor can be affiliated with several hospitals. As you compare doctors to find the right one for you, you should also consider the quality of the hospitals where the doctors work. Not all hospitals provide the same level of quality care. You are less likely to suffer a complication and more likely to survive your stay at a 5-star rated hospital. By pairing high-quality hospitals and doctors on your healthcare team, you are increasing your chances of receiving the best healthcare possible and experiencing the best results.
