Hospitals misleading patients about benefits of robotic surgery, study suggests
Date:5/18/2011

An estimated four in 10 hospital websites in the United States publicize the use of robotic surgery, with the lion's share touting its clinical superiority despite a lack of scientific evidence that robotic surgery is any better than conventional operations, a new Johns Hopkins study finds.

The promotional materials, researchers report online in the Journal for Healthcare Quality, overestimate the benefits of surgical robots, largely ignore the risks and are strongly influenced by the product's manufacturer.

"The public regards a hospital's official website as an authoritative source of medical information in the voice of a physician," says Marty Makary, M.D., M.P.H., an associate professor of surgery at the Johns Hopkins University School of Medicine and the study's leader. "But in this case, hospitals have outsourced patient education content to the device manufacturer, allowing industry to make claims that are unsubstantiated by the literature. It's dishonest and it's misleading."

In the last four years, Makary says, the use of robotics to perform minimally invasive gynecological, heart and prostate surgeries and other types of common procedures has grown 400 percent. Proponents say robot-assisted operations use smaller incisions, are more precise and result in less pain and shorter hospital stays claims the study's authors challenge as unsubstantiated. More hospitals are buying the expensive new equipment and many use aggressive advertising to lure patients who want to be treated with what they think is the latest and greatest in medical technology, Makary notes.

But Makary says there are no randomized, controlled studies showing patient benefit in robotic surgery. "New doesn't always mean better," he says, adding that robotic surgeries take more time, keep patients under anesthesia longer and are more costly.

None of that is apparent in reading hospital websites that promote its use, he says. For examp
