The decision to add a new procedure in an ambulatory surgery center (ASC) is a matter of weighing risks and opportunities. A long list of variables must be analyzed and compared. Is the prospect of higher profit worth the investment that will be required in staff and equipment? Is our patient population appropriate, physically and financially, to undergo procedures usually done in hospitals? What do our surgeons, anesthesiologists, and nurses know about the techniques they would have to master? And so on.
