Financial incentives for Ontario surgeons are likely a key factor driving greater use of laparoscopic colon cancer surgery, says a study led by a McMaster University surgeon.
The research, published online by the Annals of Surgical Oncology, found that between 2002 and 2009 there was an increase in laparoscopic versus traditional open techniques for colon and rectal cancer surgery. These increases were associated with only minimal decreases in how long patients stayed in hospital after surgery and no changes in the survival of patients.
The authors point out that in October 2005, the Ontario physician billing schedule was altered, providing surgeons with a 25% premium if laparoscopic rather than open techniques were used for colon cancer. Most of the incentives went to surgeons already enthusiastic about laparoscopic approaches.
"Our paper highlights two important issues," said principal investigator Dr. Marko Simunovic, an associate professor of surgery of McMaster's Michael G. DeGroote School of Medicine.
"First, in our publicly funded health care system we need to critically review the advantages and disadvantages of new expensive technologies or treatments before they're widely introduced into the province. Second, Ontario physicians provide high quality care to the best of their abilities - one should question the logic of financial incentives."
Simunovic added: "A 25% bonus for laparoscopic surgery sends a strong signal to surgeons that they should provide this service, even though the available evidence to date does not demonstrate superiority for laparoscopic versus open techniques."
The more expensive laparoscopic surgery usually results in a smaller visible scar and a slightly shorter hospital length of stay.
