But for this new study, published in the Archives of Surgery, the results are not as positive. Despite thorough safeguards in hundreds of different hospitals, major mistakes still happen. And doctors say the errors are likely to be underrepresented and underreported.
"Just like aviation, we want plane crashes reduced to zero," said Stahel. "This is like a jumbo jet crashing once a week. There should be zero tolerance to these complications."
But while no patient wants to be the one to have the wrong foot amputated or have a sponge left in their body, some physicians said the idea of this zero tolerance is simply impossible.
Dr. David Feldman, chief safety officer and vice chair of surgery at Maimonides Medical Center in Brooklyn, N.Y., is an advocate of safety guidelines and regimented protocols. Before each surgery, every person in his operating room introduces themselves. Doctors reiterate the patient's name and surgical site and quickly go over procedures again. Before the patient leaves the room, doctors at Maimonides, among other things, wave a detector over the patient's body designed to spot any soft items like sponges or towels if they have been left in the patient after surgery. Pathology labels are double-checked to be sure the correct name is on the labels.
But despite such cautionary practices, Feldman said he did not think surgery will soon be just right.
"We as a society have an expectation of perfection, but it's unrealistic to think surgeries will be perfect," said Feldman. "Humans are not perfect beings, and there are always going to be mistakes."
Dr. Thor Sundt, professor of surgery at Mayo Clinic, agreed.
"These errors are unfortunately inevitable because of the complexity of the business we're in," said Sundt, another strong advocate of surgery guidelines. "The trick is error management. Everyone on the team must be mindfully engaged and empowered, so they can capture those errors and correct them."
Charles Perrow, professor emeritus of sociology at Yale University, wrote "Normal Accidents," a book that examines the complex systems that surround us. The more complex the system, Perrow says the more likely there will be errors.
"When you move from one person to two persons you get a 'crack' that something might fall into," Perrow said. "With a half a dozen people in the operating room the number of possible cracks increases exponentially. We always make mistakes and we hope that others will catch them before they do too much damage, but with increased specialization the others are less likely to catch our quite specialized mistake."
Sundt and his colleagues at Mayo Clinic, meanwhile, have taken safety guidelines one step further than the university protocol. Before every surgery, Sundt pauses to confirm the name of the patient, the procedure that is about to take place, antibiotics dosage and any special equipment that is needed in the operating room. In 2010, medical briefings were also made mandatory at Mayo Clinic. While a checklist is the same for every surgery, briefings change for different surgeries. The idea is to make everyone, including the patient, comfortable enough to speak up if necessary. Even when a nurse ends a shift, he or she must brief the new nurse on the specific operation at hand.
"Everyone, including patients, needs to be part of the team and be an active participant in the process," Sundt said.
