There are a number of ways to look up a hospital's staff on their website, call hospital information in your area to ask for a plastic surgeon on staff, or researching by contacting individual practices you might consider having surgery with to inquire as to where they do their operations. However, you mention this question under the heading of "Brazilian Butt Lift..." every area is different, but there are some pretty consistent trends in that this procedure is generally done in an ambulatory surgery center as an outpatient procedure. This often comes down to economics: hospitals charge much higher fees for the facility, and patients are generally not wiling to pay the additional cost. Another thing is you list your location in California but are asking about Miami...that's a concern. Medical tourism is generally more risky because of the lack of continuity....who is going to take care of you if you have a problem a month later? If the reason behind your question is safety, then the elements you want to know are whether the facility is accredited, whether all standard of care guidelines are followed (such as use of US, staying above muscle, not going over an unsafe maximal amount of liposuction, etc...). Ultimately having this discussion with your surgeon in consultation is what will tell you whether to be comfortable with that healthcare professional.
