Dr. Mullins at Johns Hopkins studied robotic prostatectomies at 28 Maryland hospitals from 2000 to 2011. He found that for the 14 hospitals that acquired robotic technology during this period the average length of stay after prostatectomy dropped to one day. Also, the rate of readmissions to the hospital for complications went from 1.2% down to 0.3%. This has a positive impact on recovery after surgery, and makes the technology attractive for many men. It was also shown that robotic-equipped hospitals were more likely to be high-volume centers and have a higher proportion of high-volume surgeons.
