Based on performance, these ratings are a good starting point for patients selecting a surgeon. Thinkstock By Eleanor Laise, Senior Editor From Kiplinger's Retirement Report, September 2015 Need to get your gallbladder removed and not sure which surgeon is top notch? Patients facing major surgery can now use two new tools that rate surgeons based on outcomes such as deaths and hospital readmissions.See Also: SLIDE SHOW: 11 Common Medicare Mistakes SurgeonRatings.org, launched by nonprofit consumer organization Consumers' Checkbook, compares surgeons' results for 14 types of surgery, including gastric surgery and hip replacement. Surgeon Scorecard (https://projects.propublica.org/surgeons), launched by nonprofit news organization ProPublica, shows surgeons' complication rates for eight procedures. The new ratings reveal vast differences among surgeons. Surgeons ranking in the top 10% of their peers for heart valve and bypass surgery, for example, had fewer than 3% of patients die in the hospital or within 90 days of discharge, Consumers' Checkbook found. Surgeons ranking in the bottom 10% for these procedures had death rates of more than 11%.

"We've seen over time that transparency reduces errors," she says. Consumers' Checkbook and ProPublica generated surgeon ratings by analyzing recent Medicare claims data. Both rating systems seek to avoid unfairly penalizing surgeons who have more sick or frail patients by adjusting the outcomes data to allow for patients' health status and other factors. The ratings have limitations. While the ratings focus largely on deaths and hospital readmissions, "being readmitted for a complication is only part of the story," says Dr. Donald Goldmann, chief medical and scientific officer at the Institute for Healthcare Improvement. If you're having prostate surgery, he says, you'd be concerned about complications such as impotence, but "you're not going to be readmitted for that." Find the Best in the Operating Room Still, the ratings are a good starting point for patients. At SurgeonRatings.org, you can enter your zip code and choose a surgery type, and you'll see a list of surgeons and their star ratings. A five-star rating indicates the surgeon's performance was so much better than average that there's only a 2.5% chance it was the result of luck, while four stars indicate a 5% chance the outperformance was just luck. The site identifies only those surgeons with better-than-average performance.

You can enter your location to find surgeons and hospitals in your area, or search for specific surgeons or hospitals. For each surgeon, the site shows a complication rate that's adjusted to account for factors such as the health and age of the surgeon's patients. The site also shows whether that adjusted complication rate is high or low compared to peers. Both Web sites give patients an indication of the volume of procedures performed by each surgeon. "We know volume is related to better outcomes," says Goldmann. Reviewing such ratings is just one step in the process of choosing a surgeon. You'll want to check the safety record of your surgeon's hospital (read Find Hospitals That Score High). Patients should also check a surgeon's background with their state medical board, Henry says. The best state medical board Web sites offer information on the doctor's education, disciplinary history and malpractice payouts. Find links to your state board at the Federation of State Medical Boards' Web site (www.fsmb.org). Many factors that make a good surgeon are "things you can judge yourself," says Robert Krughoff, president of Consumers' Checkbook. Consider whether the doctor takes enough time to explain the procedure, listens to you and encourages you to get a second opinion before undergoing surgery.
