Lethal variability in surgical outcomes


An analysis shows that the probability of surviving any of four high-risk surgeries can vary by as much as 23 percent depending on the hospital,  Reuters reported today.

The report is by the nonprofit Leapfrog Group, a patient-safety organization supported by large employers, and Castlight Health Inc, which sells software for employers to manage healthcare spending.

Ashish Jha, M.D., of the Harvard School of Public Health, who was not involved in the Leapfrog report, told Reuters. “It’s amazing there is such variability in mortality from these common surgeries, and patients should know that.”

”Leapfrog asked 1,500 hospitals for 2013 data on four risky surgeries, including number of procedures and patient deaths. It adjusted the numbers to come up with a ‘predicted survival estimate for each,” Reuters reported.

”For pancreatectomy (removing all or part of the pancreas, usually to treat cancer), predicted survival rates ranged from 81 percent to 100 percent. Of 487 hospitals reporting data, 203 had rates of at least 91.3 percent, which Leapfrog chose as the benchmark for quality.”

”For esophagectomy (removing all or part of the esophagus), expected survival ranged from 88 percent to 98 percent. Only 182 of 535 hospitals had rates of at least 91.7 percent.”

”For repairs of abdominal aortic aneurysm, survival ranged from 86 percent to 99 percent; 268 of 792 hospitals met the benchmark of 97.3 percent.”

”For replacing the heart’s aortic valve, survival ranged from 92 percent to 97 percent; only 95 of 544 hospitals hit 95.6 percent.”

”The study didn’t analyze which kinds of hospitals – nonprofit or for-profit, in one region or another – excelled, but in general those that performed more procedures did best. National stalwarts such as Brigham and Women’s Hospital in Boston and the Mayo Clinic in Rochester, Minn.,  did well in all four surgeries, but so did Hoag Memorial in Newport Beach, Calif. and Morristown Medical Center, in New Jersey.”
