Difference between hospital and out patient surgery center?

There are differences between outpatient surgery settings that should also be considered when outpatient surgery is suggested. Ambulatory Surgical Centers are privately owned, free standing facilities that may or may not be affiliated with a hospital.

Because the ambulatory surgery center is not affiliated with a hospital, the staff may not be "on call." … If you develop complications and require emergency services or hospital admittance after your operation, hospital staff may have difficulty getting information from the ambulatory surgery centers as quickly as they could from an affiliated outpatient facility.
