Robot-assisted surgery for kidney cancer increased access to a procedure that can reduce mortality and renal failure

Abstract

Surgeons increasingly use robot-assisted minimally invasive surgery for a variety of medical conditions. For hospitals, the acquisition and maintenance of a robot requires a significant investment, but financial returns are not linked to any improvement in long-term patient outcomes in the current reimbursement environment. Kidney cancer provides a useful case study for evaluating the long-term value that this innovation can provide. Kidney cancer is generally treated through partial or radical nephrectomy, with evidence favoring the former procedure for appropriate patients. We found that robot-assisted surgery increased access to partial nephrectomy and that partial nephrectomy reduced mortality and renal failure. The value of the benefits of robot-assisted minimally invasive surgery to patients, in terms of quality-adjusted life-years gained, outweighed the health care and surgical costs to patients and payers by a ratio of five to one. In addition, we found no evidence that the availability of robot-assisted minimally invasive surgery increased the likelihood that inappropriate patients received partial nephrectomy.
