MASSDEVICE ON CALL — Robot-assisted procedures are making up an ever greater portion of hysterectomies, but researchers aren’t sure that the extra cost leads to better outcomes.
"Proponents of robotic surgery have argued that robotic technology allows women who otherwise would undergo laparotomy to have a minimally invasive procedure," according to the report. "However, there is little to support these claims, and because both laparoscopic and robotic-assisted hysterectomy are associated with low complication rates, it is unclear what benefits robotically assisted hysterectomy offers."
Hysterectomy is among the most commonly performed procedures in women, likely to affect 1 in 9 women in their lifetimes, the researchers noted.
Robot-assisted hysterectomies made up 0.5% of such procedures in 2007, but that rate had grown to 9.5% by 2010. Laparoscopic procedures also increased during that time, going from 24.3% in 2007 to 30.5% in 2010, according to the report.
"Would it be a better use of resources to train more surgeons in laparoscopic techniques than to spend the money on more robot machines?" the researchers asked. "When the innovation being advertised is of questionable advantage, direct-to-consumer promotion may only fuel unnecessary utilization."
"In the absence of additional research or decreases in price, the path taken by the medical and payer community should be one of caution," they concluded. "At a minimum, manufacturers might begin by voluntarily restricting their promotional activities."
Plastic surgery grows in 2012
Cosmetic procedures grew in popularity during 2012, with the number of procedures growing 5% in the U.S., especially among minimally invasive procedures such as Botox and microdermabrasion, according to the American Society of Plastic Surgeons.
iPhone EKG may pose more questions than answers
The FDA’s approval of the prescription-ready iPhone EKG system has doctors and mobile health enthusiasts in a flurry over how the hand-held heart monitor will fit into the clinical work flow.
Are docs soft-pedaling the impact of heart implants?
Physicians aren’t properly warning patients of the long-term impacts of having a cardiac implant, leaving patients ill-equipped to handle the potential harm to their quality of life and psychosocial health, researchers said.
