"The most valuable part of all this is when they are in the car together," says Stephen Plume, MD, professor emeritus of surgery and community and family medicine at Dartmouth Medical School, a retired staff surgeon at the Dartmouth-Hitchcock Medical Center, both in New Hampshire, and one of the founders of NNECDSG.

"The stuff we learn is remarkable," says Plume."For example, a profusionist running the heart-lung machine during surgery noticed and mentioned during a visit that a variation occurring in blood count during surgery might be related to outcomes.Data showed that it did, that there is a direct linear relationship between the red blood cell count and mortality, and that now determines how low we allow the count to go."
Another example is the use of aspirin, which is helpful in avoiding blood clots.According to Plume, the conventional wisdom had been that aspirin therapy should be discontinued weeks before surgery because it could promote internal bleeding.

"There was a big uproar, because it was the first that actually ranked and identified hospitals by mortalities," says Plume."People, including us, said the report was unfair and didn't properly reflect the demographic mix different hospitals contend with.So we set out to gather our own data and prove the HCFA study wrong."
By 1990, Plume, O'Connor, and colleagues had traveled to all the hospitals that performed heart surgery in their region, observing and gathering data on CABG and other procedures.

"We found that in our region, at least, the variation in mortality rates they reported for CABG was not due to patient mix, but was greatly affected by processes and procedures we felt we could do something about," says Plume.
It was a sobering realization, says Plume, and changed the way heart surgery is performed in New England.It was the beginning of an effort that has saved more than 1,000 lives, he says.
