Regarding the April 21 cover story (“Surgical-robot costs put small hospitals in a bind,”), if there were randomized, prospective trials demonstrating clear superiority of robotic techniques over conventional surgery, there would be an unambiguous rationale for the use of robotics. It would be a competing technology with a clinical benefit.
However, except for retrospective studies demonstrating a day or two advantage in length of stay, such evidence is lacking, and this technology has become a competitive tool for hospitals in terms of driving volume, which of course, (with the added expense of utilizing the technology without additional reimbursement), is the primary reason that hospitals purchase it.
