The top 100 hospitals are determined each year by a group called Truven Analytics.  Hospitals do not apply to receive this recognition.  Rather, the distinction of a top 100 hospital is determined by data analysis of previously defined indicators. 

In order to be considered a top 100 hospital, a hospital must be an acute care facility that serves a variety of patients.  Ten indicators are used to rank each of the hospitals.  The indicators include things such as mortality index, core measures scores, 30-day readmission rate, HCAHPS scores, among others.
