Brock Nelson remembers the final time he stonewalled a family about a hospital error.
Almost ten years ago, a teenage boy had died after doctors misdiagnosed his cancer. The boy's grief-stricken parents asked to meet with Nelson, then CEO of Children's Hospitals and Clinics of Minnesota.
"I was advised 'don't volunteer information, and don't admit or say that we made a mistake,'" he recalled. After the emotional meeting, he walked out shaking, turned to his lawyer and "vowed we're never going to do that again." Weeks later, he met with the parents again, apologized, and "shared everything we knew."
That was, by all accounts, the start of a sea change in Minnesota hospitals, which have been quietly challenging the code of silence surrounding medical mistakes.
Few go as far as the Park Nicollet Health System, which publicly admitted March 17 that the wrong kidney had been removed from a cancer patient at Methodist Hospital in St. Louis Park.
But many of Minnesota's largest hospitals are embracing the idea of fessing up to their mistakes, at least to patients and families, and trying to make amends.
That includes Regions Hospital in St. Paul, where Nelson is now CEO.
"As a whole state, I think the culture has shifted," said Dr. Phil Kibort, vice president and chief medical officer at Children's Hospitals. "In the last five, six years, we've been telling the truth."
